Airstream Touring Coach Interstate 19 2023 Introduction and Precautions User Manual

Introduction: 2023 Airstream Touring Coach Interstate 19 Safety Precautions User Manual


A warning is used for a hazardous situation that, if not avoided, could result in death or serious injury to persons.

Caution is used to advise caution when performing actions that could result in minor or moderate injury to persons and/or damage to equipment.

A note is used to address practices not related to personal injury. This applies to hazardous situations involving property damage only.
Optional items may be available on all, or particular models. Additionally, some optional items can only be included during the manufacturing phase and cannot later be added to the touring coach. The inclusion of optional items information in this manual does not imply or suggest the availability, application, suitability, or inclusion for any specific unit.

Your Mercedes-Benz Sprinter Van Operator’s and Warranty Manuals contain important cautions, warnings, and operational, and warranty information on the Sprinter and its components. All information in the Sprinter manual should be reviewed and followed for your safety. The Airstream Owner’s Manual may provide additional information and tips on the use of the van as a touring coach; however, no information in the Airstream manual should be interpreted as advice or directions to disregard or void the warnings, cautions, or other information contained in the Sprinter’s manuals.

Safety Precautions

Many things can be construed as safety-related, but the most important is your common sense. If you are careless with matches, cigarettes, flammable material, or any other hazardous material, you surely realize your potential for accidents is greatly increased. You will find many safety recommendations in this section and throughout the manual. The following recommendations are the ones we consider to be the most important.

Weight Distribution

The touring coach has fresh water and waste water tanks, a water heater, and storage areas. It gives
you great flexibility in loading. With flexibility comes responsibility. If you want to load down all the storage compartments, the amount of fluids may have to be reduced. It is a trade so plan wisely. Distribute your additional cargo as evenly as possible with the heaviest objects located as low as possible.
Do you really want to carry a full freshwater tank to an RV park 1,000 miles away and then hook up to a city water supply? Even if you’re going to a remote area, you can usually fill your water tank shortly before entering the area. Just reducing your load by 10 gallons of water lets you carry an additional 83.5 pounds of cargo.

Tire Safety

Properly maintained tires improve the steering, stopping, traction, and load-carrying capability of your vehicle. Refer to Section 9 – Maintenance for tire care and safety information.

Appliances and Equipment

The appliances (stove) and equipment (hot water heater/furnace, generator, etc.) typically operate on liquefied petroleum (LP) gas. LP gas is flammable and is contained under high pressure. Improper use may result in a fire and/or explosion. Make sure to follow all instructions and warnings in this manual as well as those in the specific owner’s manuals of the appliances and equipment.

Airstream Touring Coach Interstate 19 2023 Chemical Sensitivity User Manual

2023 Airstream Touring Coach Interstate 19 Chemical Sensitivity User Manual

Chemical Sensitivity

Immediately after the purchase of your new recreational vehicle and sometimes after it has been closed up for an extended period of time, you may notice a strong odor and/or experience a chemical sensitivity. This is not a defect in your recreational vehicle. Like your home, there are many different products used in the construction of recreational vehicles, such as carpet, linoleum, plywood, insulation, upholstery, etc. Formaldehyde is also the by-product of combustion and numerous household products, such as paints, coatings, and cosmetics. However, recreational vehicles are much smaller than your home and therefore, the exchange of air inside a recreational vehicle is significantly less than in a home. These products, when new or when exposed to elevated temperatures and/or humidity, may off-gas different chemicals, including formaldehyde. This off-gassing, in combination with the minimum air exchange, may cause you to experience irritation of the eyes, nose, and throat, as well as sometimes headache, nausea, and a variety of asthma-like symptoms. Elderly persons and young children, as well as anyone with a history of asthma, allergies, or lung problems, may be more susceptible to the effects of off-gassing.

Formaldehyde is a naturally occurring substance and is an important chemical used widely by industries to manufacture building materials and numerous household products. It is also a by-product of combustion and certain other natural processes. Thus, it may be present inside the touring coach. Ventilation of the unit normally reduces the exposure to a comfortable level. Trace levels of formaldehyde are released from smoking, cooking, use of soaps and detergents, such as carpet shampoos and cosmetics, and many other household products. Some people are very sensitive to formaldehyde while others may not have any reaction to the same levels of formaldehyde. Amounts released decrease over time.

Your Airstream touring coach was manufactured using low formaldehyde-emitting (LFE) wood products, the use of which is typical in the recreation vehicle industry. Formaldehyde has an important role in the adhesives used to bind wood products used in recreation vehicles. The wood products in your coach are designed to emit formaldehyde at or lower than industry guidelines and should not produce symptoms in most individuals.

While LFE wood products typically do not emit formaldehyde at a level that would cause symptoms in most individuals, it is possible, though not likely, for symptoms to occur when the touring coach is not properly ventilated. Ventilation is an essential requirement for touring coach use for many reasons. Any effects of formaldehyde can be greatly reduced by actions such as opening windows, opening roof vents, running the air conditioner, or some combination thereof. In addition, the emission of formaldehyde by these products naturally decreases rapidly over time. Airstream strongly suggests you take measures to properly ventilate your touring coach on a regular basis. If you have any questions with respect to proper ventilation of your touring coach, please do not hesitate to contact your dealer or Airstream.


To reduce or lessen exposure to chemicals from off-gassing, it is of the utmost importance that you ventilate your recreational vehicle. Ventilation should occur frequently after purchase and at times when the temperatures and humidity are elevated. Remember, off-gassing is accelerated by heat and humidity. Open windows, exhaust vents, and doors. Operate ceiling and/or other fans, roof AC, and use a fan to force stale air out and bring fresh air in. Decreasing the flow of air by sealing the recreational vehicle increases the formaldehyde level in the vehicle’s indoor air.

Do Not Smoke

It is recommended you do not smoke inside your recreational vehicle. In addition to causing damage to your recreational vehicle, tobacco smoke releases formaldehyde and other toxic chemicals.

Medical Advice

Questions regarding the effects of formaldehyde on your health should be submitted to your doctor or local health department.

Airstream Touring Coach Interstate 19 2023 Carbon Monoxide User Manual

2023 Airstream Touring Coach Interstate 19 Carbon Monoxide Detector User Manual

Carbon Monoxide Detector

If you hear the Carbon Monoxide alarm move everyone to a source of fresh air. When Carbon Monoxide is detected you will be alerted by 4 beeps, pause, 4 beeps, pause and the detectors LED will flash red as the alarm is sounding. If the alarm does sound exit immediately and call the Fire Department. The manual pertaining to the smoke/Carboaiven to you at the dealership. Please read and follow all care, maintenance, and safety information contained in the manual.
Carefully read and understand the contents of the provided instruction manual before using the detector. Store the manual in a safe place for future reference. Pay particular attention to the safety warnings. Pass the manual on to any subsequent users of the alarm.

Smoke/Carbon Monoxide detectors have a limited life. The unit should be replaced immediately if it is not operating properly. You should always replace an alarm after 5 years from the date of purchase. Write the purchase date on the space provided on the back of unit.

This product is intended for use in ordinary, indoor locations of family living units. It is not designed to measure compliance with occupational safety and health administration (OSHA) commercial or industrial standards. Individuals who are at special risk from Carbon Monoxide exposure by reason of age, pregnancy, or medical condition may consider using warning devices that provide audible and visual signals for Carbon Monoxide concentration under 30 ppm. If in doubt, consult your medical practitioner.

This Carbon Monoxide Detector Is Not

  • Designed to detect any gas other than Carbon Monoxide.
  • To be seen as a substitute for the proper servicing of fuel-burning appliances.
  • To be used on an intermittent basis, or as a portable alarm for spillage of combustion products from fuel-burning appliances.

This Carbon Monoxide detector is designed for indoor use only. Do not expose to rain or moisture. Do not knock or drop the alarm. Do not open or tamper with the alarm as this could cause malfunction. The detector will not protect against the risk of Carbon Monoxide poisoning when the batteries are dead or missing. The alarm will only indicate the presence of Carbon Monoxide gas at the sensor. Carbon Monoxide gas may be present in other areas.

Important Safety Precautions

  • Ideally, it is recommended that a Carbon Monoxide detector should be installed in or near every room that has a fuel burning appliance such as any room heaters, water heaters, cookers, grills, etc.
  • Ensure that the alarm horn can be heard by all those who are intended to hear it. Seek medical help if it is suspected that a user of the RV is suffering from Carbon Monoxide poisoning.
  • If the alarm sounds, make sure to investigate the problem. Ignoring the alarm may result in sickness, injury or death. (CO may be present even if nothing is seen or smelled by the user.)
  • Room spaces should be well-ventilated when household cleaning supplies are used as these may cause a false alarm.
  • The alarm should be tested once per week. If further details are required, which do not appear in this manual, contact BRK Brands Inc. First Alert.

Activation of your Carbon Monoxide alarm’s audible horn indicates the presence of Carbon Monoxide that can kill you. Leave the area immediately!

What Is Carbon Monoxide

Carbon Monoxide (CO) is a highly poisonous gas that is released when fuels are burned. It is invisible, has no smell, and is therefore very difficult to detect with the human senses. Under normal conditions, in a room where fuel-burning appliances are well maintained and correctly ventilated, the amount of CO released into the room by appliances is not dangerous. These fuels include wood, coal, charcoal, oil, natural gas, gasoline, kerosene, and propane. Common appliances are often sources of CO. If they are not properly maintained, are improperly ventilated, or malfunction, CO levels can rise quickly. CO is a real danger in air-tight vehicles with added insulation, sealed windows, and other weatherproofing that can trap CO inside.
Conditions that can result in potentially dangerous CO situations

  1. Excessive spillage or reverse-venting of fuel-burning appliances caused by outdoor conditions, such as:
    • Wind direction and/or velocity, including high gusts of wind.
    • Heavy air in the vent pipes (cold/humid air with extended periods between cycles).
    • Negative pressure differential resulting from use of exhaust fans.
    • Simultaneous operation of several fuel-burning appliances competing for limited internal air.
    • Vent-pipe connections vibrate loose from clothes dryers, furnaces, or water heaters.
    • Obstructions in or unconventional vent-pipe designs can amplify the above situations.
  2. Extended use of un-vented fuel-burning devices.
  3. Temperature increase that can trap exhaust gases near the ground.

Airstream Touring Coach Interstate 19 2023 Maintenance User Manual

2023 Airstream Touring Coach Interstate 19 Regular Maintenance User Manual

Regular Maintenance

The Smoke/CO detector has been designed to be as maintenance-free as possible, but there are a few simple things you must do to keep it working properly. Use only listed replacement batteries. The unit may not operate properly with other batteries. Never use rechargeable batteries since they may not provide a constant charge.

The battery door will resist closing unless batteries are installed. This warns you that the unit will not operate without batteries.

Carbon Monoxide is poisonous and can cause confusion, unconsciousness, and death. Follow all instructions, cautions, and warnings in this section and the generator operator’s manual.

NEVER ignore any alarm. Failure to respond can result in injury or death. The Silence Features are for your convenience only and will not correct a problem. Always check your touring coach for a potential problem after any alarm. Failure to do so can result in injury or death.

Liquid Propane Gas (LPG)/Carbon Monoxide (CO) Detector
Airstream Travel Trailer Bambi 2023 Tire Inspection and Storage User Manual 02

This detector has a five-year life; see end-of-life notification in the detectors manual. Please read the entire detector manual before operating the unit. The LPG/CO detector is located in the galley area. LPG is a mixture of gases produced and sold commercially as a fuel for heating and cooking appliances. LPG is highly flammable and, as a result, can be explosive if ignited under certain circumstances. LPG is heavier than air and, if confined in a closed space, will accumulate close to the floor. The LPG/CO detector is designed to alarm when propane gas exceeds 10% of the lower-explosive-limit for more than 30 seconds or if CO gas reaches unsafe levels. When propane gas is detected the horn will sound with constant beeps and the red LED will be on. If CO gas is detected the horn will sound with 4 rapid chirps followed by a 4 second pause and the red LED will flash rapidly. Your LPG/CO detector is wired directly to your touring coach battery and incorporates a 1-amp, in-line fuse. It has no internal battery backup. In normal stand-by mode, the LED indicator will be green.

Low Voltage
The operating voltage for the detector is 12 VDC. The actual voltage supplied to the detector in a recreational vehicle may drop below the minimum 8 VDC. The detector provides the user with a low voltage warning before reaching that level and will provide additional distinct, clear warnings and alarms after the 8 VDC level is reached. However, if available power supplied to the unit is below the operating voltage of 8 VDC, the detector will not detect gas or provide protection against dangerous levels of LPG.

If the low voltage warning sounds, the detector will need to be reset by disconnecting the battery, before normal operation will occur.

Detector Test
If the Silence/Test button is pressed while in normal operation, the alarm will perform a self test of the CO sensor, propane sensor and battery voltage. It is recommended to perform a self-test weekly, after powering up from storage, and before each trip. If the self test passes, the alarm will perform 2 cycles of the CO horn pattern (4 rapid chirps followed by a 4-second pause), followed by 2 cycles of the propane horn pattern (constantly beeping).

Activation of this detector indicates the possible presence of LPG, which can cause an explosion and/or fire, causing serious injury or death. This normally indicates a leak in the LPG installation or an LPG appliance. Extinguish all open flames, open your windows and door, and evacuate the unit immediately. Do not activate any electrical switch. Turn off the LPG using the remote shut off switch. Do not re-enter your unit until a qualified repair technician has corrected the problem and certified the system as safe.

It is not recommended that the detector be disconnected from the battery during periods of storage. There is a small heater on the sensor of the device that burns away impurities in the air during periods of normal use. During periods when power is interrupted, impurities can build up on the sensor. When power is returned to the detector, the detector alarm may activate until the impurities are burned off. This could take a number of hours, during which time the alarm will be constantly on.

Have a qualified technician check your LPG system annually or if you detect any signs of leaks or malfunctions.

Refer to Section 5 – Interior and Section 6 – Exterior for additional LPG warnings and safety information.

Basic LPG Safety Information
A warning label has been positioned in the cooking area to remind you to provide an adequate supply of fresh air for combustion. Unlike homes, the amount of oxygen supply is limited due to the size of the recreational vehicle, and proper ventilation when using the cooking appliances will avoid dangers of asphyxiation. It is especially important that cooking appliances not be used for comfort heating as the danger of asphyxiation is greater when the appliance is used for long periods of time. Portable fuel-burning equipment, including wood and charcoal grills and stoves, shall not be used inside the recreational vehicle. The use of this equipment inside the recreational vehicle may cause fires or asphyxiation. A Warning Label has been located near the LP gas container. This label reads: DO NOT FILL CONTAINER(S) TO MORE THAN 80% PERCENT OF CAPACITY. Overfilling the LP gas container can result in uncontrolled gas flow that can cause a fire or explosion. A properly filled container will contain approximately 80 percent of its volume as liquid LP gas.

  2. ONLY those portions of a NEW motorhome not excluded under the section “What is Not Covered”, when sold by an authorized dealership; and,
  3. ONLY defects in workmanship performed and/or materials used to assemble those portions of your motorhome not excluded under the section “What is Not Covered”. “Defect” means the failure of the workmanship performed and/or materials used to conform with the design and manufacturing specifications and tolerances of Airstream. The Limited Warranty is transferable and the subsequent owner’s warranty coverage period shall be the unexpired balance of the original warranty coverage period. A completed copy of the Warranty Transfer Form must be submitted to Airstream at the time of resale.

When you request and accept the performance of warranty repairs under the terms of this Limited Warranty, you are accepting all terms of this Limited Warranty, including by way of example, warranty limitations and disclaimers, the forum selection clause and the clause reducing the time period when suit must be filed for breach. If any term of condition in this limited warranty conflicts with your state’s Uniform Commercial Code (“UCC”) as interpreted by courts within your state, the provisions of your state’s UCC are varied as allowed for by USS 1-302.

Coverage Ends
36 months after the first retail owner first takes delivery of the motorhome from an authorized dealership or after the odometer reaches 36,000 miles, whichever occurs first. Any action for breach of this warranty or any implied warranties must be commenced not more than 37 months after the breach. Some states do not allow the reduction of the time when a breach of a warranty claim must be commenced, so the reduction in time when a breach of a warranty claim must be commenced may not apply to you.

Limitation Of Implied Warranties

Implied warranties arising under applicable law, if any, including but not limited to implied warranties of merchantability or fitness for a particular purpose, are hereby limited in duration to the term of this limited warranty and are limited in the scope of coverage to those portions of the motorhome covered by this limited warranty. There are no express warranties or any implied warranties of merchantability on those portions of the motorhome excluded from coverage. There is no warranty of any nature made by Airstream beyond that contained in this limited warranty. No person has the authority to enlarge, amend or modify this limited warranty. The dealer is not airstream’s agent. Airstream is not responsible for any undertaking, representation or warranty made by any dealer or others beyond those expressly set forth within this limited warranty. Some states do not allow limitations on how long an implied warranty lasts, so the above limitations may not apply to you.

Disclaimer Of Incidental And Consequential Damages

Airstream disclaims any and all incidental and consequential damages, including but not limited to expenses such as transportation to and from dealerships and Airstream repair facilities, loss of time, loss of pay, loss of use, inconvenience, commercial loss (including but not limited to lost profits), towing charges, bus fares, vehicle rental, service call charges, gasoline expenses, incidental charges such as telephone calls and facsimile transmissions, and expenses for lodging and moisture damage such as mold and mildew as well as rust and corrosion. This disclaimer is independent of any failure of the essential purpose of any warranties provided with the motorhome and shall survive any determination that a warranty failed of its essential purpose. Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation or exclusion may not apply to you.

Repair Remedy

Airstream’s sole and exclusive obligation is to repair any covered defects discovered within the warranty coverage period if:

  1. within 10 days of your discovery of a defect you notify Airstream OR an authorized dealership of the defect; AND
  2. you deliver your Motorhome to Airstream OR an authorized dealership at your cost and expense.

Back-Up Remedy

If the primary repair remedy fails to successfully cure any defect after a reasonable number of repair attempts, your sole and exclusive remedy shall be to have Airstream pay an independent service shop of your choice to perform repairs to the defect OR if the defect is incurable, have Airstream pay diminution in value damages. The repair remedy and the backup remedy must both be exhausted and these remedies must fail to fulfill their essential purpose before you can seek other legal or equitable remedies for breach of this express warranty or for breach of any implied warranty. This limited warranty is not a warranty that promises or extends to future performance because the warranty does not make a representation on how your motorhome will perform in the future but instead represents only what the remedy will be if a defect exists.

Unless prohibited by state law, repairs will not extend the time when you must commence a breach of warranty claim and shall not extend the warranty coverage period. Any performance of repairs after the warranty coverage ends OR any performance of repairs to those portions of your motorhome excluded from coverage shall be considered “goodwill” repairs. Warranty repairs should be expected. Airstream may use new and/or remanufactured parts and/or components of substantially equal quality to complete a repair. Damage to the interior or exterior surfaces, trim, upholstery and other appearance items may occur at the factory during assembly, during delivery of the motorhome to your selling dealer or on the selling dealer’s lot. Normally, any damage is detected and corrected at the factory or by the selling dealer during the inspection process. If you discover any damage when you take delivery of your motorhome, you MUST notify your dealer OR Airstream within 10 days of the date of purchase to have the damage repaired at no cost to you. Minor adjustments, such as adjustments to the interior or exterior doors, drawers, and latches will be performed at no cost to you by your selling dealer during the first 90 days of warranty coverage; thereafter, such adjustments are your exclusive responsibility as normal maintenance.

Overnight Stop

In time you will develop a knack for spotting wonderful little roadside locations by turning off the main highway and exploring. There are many modern recreational vehicle parks, including State, County, and Federal parks with good facilities, where you may obtain electrical, water, and sewer hookups and connections. Directories are published which describe in detail these parks and tell what is available in the way of services and hookups. All you need to do to enjoy the self-contained luxury while boondocking is to:

  1. Turn on the 12-volt battery disconnect switch to provide power to your components.
  2. Turn on the exterior LP gas supply, if you need to cook or start the generator.
    • Generator must be started to run the air conditioner.
    • Inverter will need to be turned on to power the entertainment devices. To conserve battery power, turn off the inverter when not in use.
  3. Turn on the water pump and open faucets until air is expelled from the system. Before moving on, turn off the LP gas and water pump. Check your campsite, both for cleanliness and to be sure you have not left anything behind. Make sure everything is properly stowed.

overnight or Weekend Trips
On overnight or weekend trips, chances are you will not use up the capacity of the holding tanks. Deplete the water supply, if using the system moderately or conservatively. You will need to maintain the level of your battery during this time. The batteries will shut down at 10.5 volts. It is recommended you charge the batteries, by plugging into shore power or by starting your generator, when they reach 12 volts.

Airstream Touring Coach Interstate 19 2023 Leveling User Manual


When you plan to stay in the same place for several days, weeks, or months, you will want your touring coach to be as level as possible. Check the attitude with a small spirit level set on the inside work counter. If a correction is necessary, then you must first level from side to side. This can be done most easily by driving up a small ramp consisting of 2 in. x 6 in. boards tapered at both ends. Airstream does not recommend placing tires in a hole for leveling. Refer to Section 7 – Sprinter Van for more information on tires.

Effects of Prolonged Occupancy
Your touring coach was designed primarily for recreational use and short-term occupancy. If you expect to occupy the touring coach for an extended period, be prepared to deal with condensation and the humid conditions that may be encountered. The relatively small volume and tight compact construction of modern recreation vehicles mean that the normal living activities of even a few occupants will lead to rapid moisture saturation of the air contained in the touring coach and the appearance of visible moisture, especially in cold weather. Just as moisture collects on the outside of a glass of cold water during humid weather, moisture can condense on the inside surfaces of the touring coach during cold weather when relative humidity of the interior air is high. This condition is increased because the insulated walls of a recreation vehicle are much thinner than house walls. Estimates indicate that two adults can vaporize up to one-and-a-half gallons of water daily through breathing, cooking, bathing, and washing.

Unless the water vapor is carried outside
by ventilation or condensed by a dehumidifier, it will condense on the inside of the windows and walls as moisture, or in cold weather as frost or ice. It may also condense out of sight within the walls or the ceiling where it will manifest itself as warped or stained panels. The appearance of these conditions may indicate a serious condensation problem. When you recognize the signs of excessive moisture and condensation in the touring coach, action should be taken to minimize their effects.

Your touring coach is not designed, nor intended, for permanent housing. Use of this product for long-term or permanent occupancy may lead
to premature deterioration of the structure, interior finishes, fabrics, carpeting, and drapes. Damage or deterioration due to long-term occupancy may not be considered normal, and may under the terms of the warranty constitute misuse, abuse, or neglect, and may therefore reduce the warranty protection.

To avoid condensation problems, try to follow these tips to help alleviate excess moisture:

  • Allow excess moisture to escape to the outside when bathing, washing dishes, hair drying, laundering, and using appliances and non-vented gas burners. Always use an exhaust fan when cooking.
  • Keep the bathroom door closed and the vent or window open when bathing and for a period of time after you have finished.
  • If you are experiencing condensation, you may want to reconsider hanging wet clothes in the touring coach to dry.
  • In hot weather, start the AC early as it removes excess humidity from the air while lowering the temperature.
  • Keep the temperature as reasonably cool during cold weather as possible. The warmer the vehicle, the more cold exterior temperatures and warm interior temperatures will collide on wall surfaces, thus creating condensation.
  • Use the ceiling vent to keep air circulating inside the vehicle so condensation and mildew cannot form in dead air spaces. Allow air to circulate inside closets and cabinets (leave doors partially open). Please keep in mind that a closed cabinet full of stored goods prevents circulation and allows the exterior temperature to cause condensation.
  • The natural tendency would be to close the vehicle tightly during cold weather. This will actually compound the problem. Simply put, you need to remove some of the warm air and allow some cool outside air to get inside the vehicle so the furnace will not recycle the humid interior air.
  • Minimize the use of incandescent lights, which produce heat and contribute to condensation.

About Molds

What are molds
Molds are microscopic organisms that naturally occur in virtually every environment, indoors and out. Outdoors, mold growth is important in the decomposition of plants. Indoors, mold growth is unfavorable. Left unchecked, molds break down natural materials, such as wood products and fabrics. Knowing the potential risks is important for any type of homeowner to protect their investment.

What factors contribute to mold growth
For mold growth to occur, temperatures, indoors or outdoors, must be between 40°F and 100°F and also, there must be a source of moisture, such as humidity, standing water, damp materials, etc. Indoors, the most rapid growth occurs with warm and humid conditions.

How can mold growth be inhibited?
By controlling relative humidity, the growth of mold and mildew can be inhibited. In warm climates, use of the air conditioner will reduce the relative humidity. Vents are located in the bathing and cooking areas and constant use is advised during food preparation and bathing, even during colder weather. Additionally, opening a window during these activities will assist in ventilation. In extremely humid conditions, the use of a dehumidifier can be helpful. If using a dehumidifier, please read and follow all manufacturer instructions and recommendations to the use and cleaning of the dehumidifier. Frequent use of your touring coach or cleaning regularly is an important preventive measure. Further, any spills should be wiped up quickly and dried as soon as possible. Avoid leaving damp items lying about. On safe surfaces, use mold or mildew-killing cleaning products. Check sealants regularly, and reseal when necessary to avoid water leaks. Proper preventive maintenance to the touring coach and its accessories, as described both in this manual and in the Airstream Touring Coach Interstate 19 2023 Information and Cleaning User Manualaccompanying literature, will provide the best protection to the touring coach.

Airstream Touring Coach Interstate 19 2023 Information and Cleaning User Manual

2023 Airstream Touring Coach Interstate 19 Cleaning Tips User Manual

General Information and Cleaning

The interior of each Airstream Touring Coach has been designed for comfort, convenience, durability, and appearance. How you use it and how you take care of it, naturally, depends on you. However, if you learn to operate the interior components and take care of them and the touring coach properly, this knowledge will add to your pleasure, as well as the long life of your touring coach. All material should be professionally dry cleaned to remove any overall soiled condition.


The best way to keep your Ultra leather seating looking great is regular cleaning to prevent excess dirt from accumulating. To help extend the life of the fabric, wipe up spills as soon as they occur. Clean with soap and water. Sanitize using disinfectants such as (1:5) bleach/water solution. For stubborn stains, wipe them off with isopropyl alcohol as soon as possible. Thoroughly rinse all solution residue with clean water and air dry.

Never remove cushion covers for separate dry cleaning or washing. Any tumble cleaning method can destroy the backing, and/or shrink or otherwise damage upholstery fabric.

Cabinets and Overhead Lockers
The furniture is manufactured from a high-pressure laminate and can be cleaned with soap and water, or you can use a common solvent on tough spots. Furniture polish can be used sparingly. Plexiglass doors must be cleaned with an anti-static cleaner and cloth. Windex or common ammonia products will damage the coating on the surface.

Do not use any abrasive material, abrasive cleaners, cloths, and pads as there is the possibility they could scratch the surface.

Aluminum Interior Skin

The metal interior skin on the ceiling is coated with a baked-on acrylic coating. Use soft rags or wash mitts always moving lengthwise with the grain of the aluminum. NEVER rub hard on the coating. Oil, grease, dust, and dirt may be removed by washing with a 5 percent solution of commonly used commercial and industrial multi-purpose detergent in water. Cleaning should be followed by a thoroughly clean water rinse. Drying the metal with a chamois or a soft cloth may prevent spots and streaks. When washing or waxing the metal, always wipe “with” the grain of the metal. A good grade of nonabrasive automotive paste or liquid wax once a year will increase the life of the finish. Abrasive polishes or cleaning solvents such as automatic dishwashers or acid etch cleaners are too strong and should never be used. Rinse all grit from the surface prior to washing. Use soft rags always moving lengthwise with the unit. NEVER rub with excessive pressure on the coating. Even the softest rag will damage the coating if excessive pressure is applied.

Counter Area

The countertops are made of a solid surface and can be cleaned with soap and water, or you can use a common solvent on tough spots. Do not use abrasive cleaners since they could scratch the surface. A protective pad should always be used under hot utensils or pans. Light sanding of minor damaged areas can repair the counters. The color of the material is constant and not just a surface coat.


Cleaning can be accomplished using a mild liquid detergent on a soft cloth. A complete homeowner’s guide for your sinks is supplied in your owner’s packet. Please read these instructions before use.

Luxury Woven Vinyl Floor

One of the best ways to keep the floor looking good is to wipe fabrics off on a weekly basis with clean water. This helps prevent dirt from becoming deeply embedded in the fabric and eliminates the need for more vigorous cleaning. For general or light cleaning, brush off loose dirt and wipe down the floor. Prepare a solution of water and mild soap such as dishwashing liquid or household cleaner. Using a soft bristle brush to clean, apply a small amount of water and soap mixture to the stain. Rinse thoroughly until all soap residue is removed. Allow the floor to air dry. For more stubborn stains and mildew, prepare a solution of 1 cup bleach and 1/4 cup mild soap per gallon of water. Apply a small amount of bleach and soap mixture to the stain and blot with a sponge or clean towel. Rinse thoroughly to remove all soap residue. Allow airing dry. A citrus-based cleaner like D-Limonene can be used for tough dirt and grease spots. Ammonium-based products are NOT recommended. All cleaning products need to be rinsed off thoroughly and air-dried after cleaning.

Rubber backing on doormats may result in yellow discoloration of the floor immediately beneath. Choose a natural fiber mat. Mats provided by Airstream are intended for use outside of the travel trailer. Rubber feet on furniture may cause staining. Remove them altogether or place coasters or felt pads between them and the floor.

Airstream Touring Coach Interstate 19 2023 Electrical User Manual

2023 Airstream Touring Coach Interstate 19 Interior Electrical Guide


12-Volt System
The major portion of electrical power in your Airstream is 12 volt. The 12-volt current powers almost every thing except the roof A/C, water heater, 120-volt receptacles, and microwave oven. However, some of these appliances have 12-volt electronic boards. All 12-volt current is routed to a 12-volt fuse block. The fuse block is the hub of the 12-volt system tying together the inverter/charger and house batteries. Power from the fuse block goes to a buss bar holding Type 2 thermal breakers. The thermal breakers then feed electrical components throughout the touring coach. One of the thermal breakers is fed by the house solar controller, providing some supplemental power, under ideal weather conditions. Power is routed from the battery disconnect to the 12-volt distribution panel and through its branch circuits to the rest of the touring coach.

Thermal breakers break contact when overheated by a short or overload in the wiring. These breakers automatically reset when cooled down. A breaker continually overheating and breaking contact should be investigated by a qualified service technician.

12-Volt Operation
The only thing you have to do is make sure the house batteries do not run down. This should not be an issue if you are plugged into an external AC power source at night or when camping. When you’re plugged into shoreline power, or running the generator, the converter charges the batteries and carries much of the load. Some nights you may not find a place to plug into city power. This should not be a problem as well; you can continuously run your interior lights, water pump, and vents for about 8 hours on a full charge. However, you should monitor your battery voltage and start the generator, if needed. Fully charged house batteries will provide approximately 8 hours of moderate 12-volt usage. If the inverter is being used extensively the house batteries will be depleted much quicker. If you are not plugged into city power, and you plan on staying longer than a day or two, you will want to conserve your batteries by using as few lights and appliances as possible. Check the monitor system regularly. It’s much easier on the batteries if you start the generator or run the chassis engine before the batteries run down. The generator starts from the house batteries so it must be started before they are depleted. If the house batteries become depleted, the chassis engine can be started to charge them. It could take a few minutes before the house batteries are charged enough to start the generator. The engine battery and house batteries are isolated from each other by a DC-DC converter, preventing the two systems from drawing down simultaneously.

Ceiling and Directional Lighting
The Multiplex System touchscreens control the LED lighting throughout your Airstream. The “Home” and
“Lights” screens have a “Light Master” switch that will allow you to instantly turn all the interior lighting in your touring coach, on or off.

Light Master Memory Feature:
The Light Master function has a memory. If you turn off individual lights and then press Light Master OFF, it will recall what lights were on the next time you press Light Master ON, and only those lights will come on. Hold the Light Master ON for more than 1 second to reset the memory and turn on all the interior lights.

Light Master LOCK Feature:
If Light Master OFF is held or pushed twice, the Light Master On will not respond. Hold the Light Master ON to resolve.

Since your Airstream has LED lighting, there are no lights to change. If an LED light stops functioning, it will require service or replacement.

Multiplex System
The Firefly Multiplex System provides advanced automation and mobile electrical solutions for your touring coach. Firefly is a multiplex network system that combines multiple signals across a media to reduce wires and simplify end-user control. The system combines all desired functions and controls of the touring coach into a simple touchscreen interface that allows you to control many systems. Each button illuminates when pressed, indicating the circuit is either ON or OFF. The button will turn white when the circuit is OFF and blue when it is ON. Buttons controlling circuits such as Light Master and Panel Lights typically do not change from blue to white.

Systems Controlled By Firefly

  • All lights (inside and outside)
  • Power awning and awning lights
  • Shades
  • Roof vent
  • Climate

Airstream Touring Coach Interstate 19 2023 Energy Management User Manual

2023 Airstream Touring Coach Interstate 19 Energy Management User Manual

Energy Management System (EMS)

The Energy Management System is located in the rear roof locker above the TV. A complete, detailed EMS manual is included with your owner’s packet.
The ENERGY MANAGEMENT SYSTEM controls 120-volt operated circuits to help keep the total 120-volt current draw to less than 30 amps. When operating on generator power the 120-volt draw will be less than 20 amps. These circuits may be any type load, but are typically heavier loads, those whose use can be “postponed” until a time when current is available for their use.

Circuit Protection

Circuit protection for ALL 120 VAC loads are standard residential resettable circuit breakers install in the Power Center (120 VAC section). Airstream has pre-installed the correct breakers per RVIA (NEC) listing requirements for the touring coach. The MAIN breaker for the touring coach is 30 amp and feeds the branch-breakers in the breaker box. Shutting off the MAIN breaker will remove power to all branch loads, except for receptacles on the Inverter circuit when the inverter mode is “ENABLED”. The Inverter/converter contains a resettable 20 amp input breaker and a 15 amp output breaker. The remaining power center branch-breakers feed individual loads and are defined by the label affixed next to the breakers. The source for 120 VAC power to the power center can come from either the shoreline plug when connected to a campsite or the touring coach’s generator, when running. If plugged into shoreline power, and the generator is started, the power feed to the power center will be coming from the generator.
The main and general load branch-breakers are operated similar to a light switch with up as “ON” and down as “OFF”. If an overload condition or a short occurs the switch will snap to the “OFF” position.

The load for this breaker will now be “OFF”. Before resetting the breaker be aware of any device that may have been plugged in or turned “ON” which may have caused the breaker to overload. Unplug or turn “OFF” the possibly faulty device before resetting the breaker. To reset the breaker, you will need external AC power going to the breaker box (shoreline or generator), then firmly push the breaker switch to the “OFF” position then back to the “ON” position. If the breaker snaps back to the “OFF” position while resetting, a fault condition still exists and should be serviced by a qualified Service Technician. If the breaker stays “ON” but snaps back to “OFF” after plugging in or turning ON the possibly faulty device a fault condition may exist in that device and should be serviced by a qualified Technician.
The power center Ground Fault Interrupt Circuit (GFCI) breaker is a special breaker that will provide additional safety to the occupants of the touring coach on the following receptacles; external, galley, lavatory, and entertainment. In addition to short circuit and overload protection the GFCI will shut off the breaker if any current feeding out of the breaker does not return to it. As in the case of a person contacting the electrical energized part of the GFCI circuit and an electrically conductive object not associated with the circuit. Refer to Ground Fault Circuit Interrupter and GFCI Breaker Test in this section for more information.

In operation, when 120 VAC and 12 VDC are initially applied, the system will energize the relays at one second intervals, closing the normally open contacts on each of the relays while monitoring the total current. If the total should exceed the service limit, the system will turn off the last load that was turned on. As it does this, it calculates the amount of current that was removed, which is the value for that load. This value is placed in memory. The system has “learned” the amount of current that particular appliance draws. This feature compensates for the difference in current draw over a range of line voltage and ambient temperature, by relearning the load each time it is turned off. The system now waits until the total current is lower than the service limit, by the amount in memory, before it will turn that load back on. This ensures that there is sufficient current to operate the load.

Display Panel
Airstream Touring Coach Interstate 19 2023 Energy Management System (EMS) User Manual 01

The display panel requires little user interaction and is provided to help the user understand power management. The display monitors the total AC current of the touring coach and prevents circuit breaker tripping by momentarily shedding loads. As additional appliances are turned on the system will begin to shed loads. As appliances are turned off, and a minimum of two minutes has expired, the system will automatically restore power to each of the shed loads.

The “Select” button allows the service type to be set to either 15, 20, or 30 amps to match the incoming service. When power is first applied, the system will be in the 30 amp mode and the screen will display “Service 30A”. Momentarily pressing the “SELECT” button will switch the system to the 20 amp mode. Momentarily pressing the button again will switch the system to the 15 amp mode. Press the “SELECT” button to switch to either 15 or 20-amp service if it is necessary to use an adaptor or you know the shoreline power is 15 or 20 amps, The screen will display either “Service 15A” or “Service 20A”.
The generator supplies 20 amp service and is set to switch the system automatically to the 20 amp mode whenever the generator is the power source. The screen will display “Generator 20A” when the generator is supplying power.

2023 Airstream Touring Coach Interstate19 Auto Generator Start User Manual

Automatic Generator Start (AGS)

Airstream Touring Coach Interstate 19 2023 Automatic Generator Start (AGS) User Manual 01

Your touring coach is equipped with an Automatic Generator Start System (AGS) which provides an optional automatic control of your onboard generator The purpose of an AGS system is to automatically start (and run) the generator when the 12 volt electrical system (house batteries) drops to a pre-determined level. The AGS can be enabled to monitor the house battery bank and when it reaches a certain level, the generator will automatically start, sending a charge to your batteries. This protects the system so that your batteries will not go down farther. Once the batteries receive a sufficient amount of charge, the generator will automatically turn off. If you are in a location for an extended period of time, this can help protect battery bank when shore power is not available. You may also have the ability to set predetermined times so that it will not start during the night or during posted quite times in a campground. Once enabled, AGS will remain enabled until the Sprinter Ignition is cycled or the generator is manually operated. Carbon Monoxide (CO) is a highly poisonous gas. Moving Parts and electricity can cause severe personal injury or death.

To reduce exposure to these hazards, always disable AGS before

  1. Sleeping in the vehicle, unless equipped with a working Carbon Monoxide detector
  2. Parking vehicle in a garage or confined space
  3. Parking vehicle for storage
  4. Servicing generators, batteries or other electrical appliances
  5. Fueling vehicle

Exposure to carbon monoxide, moving parts, and electricity hazards are possible due to the unexpected starting of the generator while in Auto Start mode.

120-Volt Power
When you’re plugged into shoreline power or starting your generator, a 120-volt current is fed to an Automatic Switch Over Box. Power from the box runs to the 120-volt circuit breakers on the Energy Management System

Make sure to read, understand, and follow all electrical component owner’s manuals provided in the owner’s packet before operating the touring coach. Observe all operating instructions and Warnings as well as all recommended maintenance schedules and procedures.

120-Volt Automatic Switch Over Box
The switchover box automatically switches the 120-volt feed to the Energy Management System Module from shoreline to generator and back as you choose which way to power the touring coach. You simply decide whether to plug into a 120-volt shoreline or start the generator and the box will do the rest. If the generator is accidentally started while plugged into the shoreline the box will sense the generator incoming power, contact points inside the box will switch cutting the shoreline connection, and establishing the generator connection. This protects the system from a possible overload from dual power sources.

2023 Airstream Touring Coach Interstate 19 Exterior Care User Manual

Exterior Care

The exterior of your Airstream Interstate 19 Touring Coach, except for the body kit, has been painted by Sprinter. The care of the paint is detailed in the Sprinter manual. The following additional information is provided by Airstream to help you understand the finish and its care. Following these instructions will provide a long-lasting, high-gloss finish for your recreational vehicle. These same procedures can also be applied to your everyday automobile, producing the same long-lasting results.

Information on finish care may provide additional information and tips on the use of the Sprinter Van as a touring coach, however, no information about the exterior finish of your touring coach in this manual should be interpreted as advice or directions to disregard or void the warnings, cautions, or other information contained in the Sprinter’s manuals.

Waxes and Polishes

Over 90 percent of all automotive finishes are clear coat. The finish on your touring coach is a state-of-the-art Acrylic Urethane Basecoat/Clear Coat. This means you will wash and polish a clear urethane coating designed to protect the basecoat: the pigmented coating that provides color. As its main function is protecting the basecoat, the clearcoat needs to be maintained especially in harsh environments. Clearcoats do not fade themselves but appear to fade or lose gloss as the surface becomes contaminated by the environment. If this contamination is not removed frequently, the result will be a dull or low-gloss finish. Occasional washing alone will not adequately remove some forms of contamination and polishing will be required.

Polishes and waxes primarily serve the following purposes:

  1. To remove minor surface imperfections caused by water spots and acid rain
  2. To remove minor scratches by filling them and leveling the surface
  3. To beautify the paint finish appearances with more depth and high-gloss
  4. To protect the paint finish from the elements

Do not use products that contain harsh abrasives such as rubbing or polishing compounds. These products should be used by experienced technicians with the proper training and equipment. Most polishes and waxes are designed to clean and polish in one application.
A hand-applied polish or wax will offer outstanding performance and protect the touring coach finish. When applying polish or wax, do so in a shaded area making sure the surface is at the specified temperature according to the polish manufacturer’s recommendations. Due to the variations of polishes and waxes, incorporate the following suggestions into the polishing technique:

  1. Condition the polishing pad by rubbing a slight amount of polish on it.
  2. Use only the amount of polish specified in the label directions.
  3. Work a small area at a time.

Sections 6 and 9 contain additional information about these components. Mid-production changes may affect the exact location of the features shown above.

  1. . Solar Port: designed as a quick plug-in for a  portable solar charging kit.
  2. The exterior 120-volt outlet provides an exterior GFCI-protected electrical source when plugged into shore power or when the generator is running.
  3. LP tank remote fill and shutoff location.
  4. Sliding step with auto retract has a step-out warning buzzer and a lock extended switch for easy entry into the touring coach.
  5. The power-boosted omnidirectional TV antenna is wired into TV outlets on the exterior of the coach and inside unit at the entertainment center cabinet.


Clean your touring coach windows the same way you clean the windows in your home. Clean the seals with a damp cloth and mild detergent every 3 to 6 months. Do not use strong solvents, as they will damage the seals. A coat of natural silicone lubricant applied after the seal has dried will keep it flexible. Spread the lubricant evenly with a brush or finger, working it into the surface. This is good practice for all rubber seals in your touring coach.

Failure to properly clean and lubricate the window seals could result in the window sticking to the jamb and should only be released by a qualified technician trained in the procedure. Do not force, pry, or apply great pressure to open the window. Failure to heed this warning may cause the window to shatter and/or cause personal injury. For replacement of a damaged window, contact an Airstream Service Center.

Gravity Water Fill

The gravity water fill is located on the backside of the galley cabinet. It is used to fill the fresh water tank with potable water. A small vent is located next to the port to allow air to expel from the tank as it is filled.
Fill the water tank by opening the sliding door. A high-pressure RV/Marine FDA-approved drinking water hose of at least ½-in. diameter made from material that is tasteless, odorless, and non-toxic can now be inserted. It’s a good idea to let the water run through a hose for a short time to flush it out. RVers sometimes fill their tanks with “home” water to avoid strange water that may be distasteful to them on short outings. Remember, the more water you carry in the Fresh Water tank, the less cargo-carrying capacity you have for other items. The amount of water in the tank may be checked on the Multiplex Control Panel.

Since the freshwater tank fill is essentially in the interior of the unit. Please monitor the amount of water you are putting into the tank to ensure that you do not have overflow into the coach.

City Water HookupAirstream Touring Coach Interstate 19 2023 Curbside Exterior Components User Manual 04

The city water hookup is located on the roadside of the touring coach. For consistent water flow and plumbing line safety, an in-line regulator limits pressure to 50 psi. Use a tasteless, odorless, non-toxic, high-pressure hose of at least 1/2 in. diameter designed for touring coach use. The city water inlet is a standard garden hose thread. We suggest you carry two lengths of hose in order to reach hookups farther away than normal, as well as to have a spare.
After hooking up the hose and turning on the city water valve provided in the park, slowly open a faucet. There will be a lot of spurts and sputtering until all the air is expelled from the touring coach system. It may take some time before all the air is expelled and a steady flow of water occurs. Once a steady flow is achieved at one faucet, the others should be opened long enough to expel the air in the lines going to them.

Airstream Touring Coach Interstate 19 2023 Solar Ports User Manual

2023 Airstream Touring Coach Interstate 19 Solar Ports User Manual

Solar Ports

In addition to the 150 watts of solar power dedicated to your house batteries, your Airstream has two external ports that allow for the plug-and-play connection of additional solar panel arrays. There is a solar port on each side of the touring coach. There are limitations when considering which aftermarket panels to buy or how to build an external array. First, ensure the aftermarket solar panels do NOT include a solar controller/regulator. The system already has a controller. Connecting a second portable controller will negatively affect the system. The maximum total input for all solar power is 500 watts, and the touring coach is already factory-equipped with 150 watts (4.2 amps at 35 volts). Therefore, the maximum input for external solar power through the ports is limited to 350 watts. To achieve optimum results, the voltage of your external array should closely match the 35 volts of the existing rooftop array. If not, the circuit will dump and waste the lower voltage supply. Check the aftermarket solar panel manufacturer’s information on the solar panels you intend to use. Airstream recommends mimicking the factory-installed rooftop solar array using Merlin-manufactured solar panels, wired in “series,” when constructing your setup. Wiring the panels in “parallel” could potentially exceed the controller’s rating.

Portable solar panels/arrays must not exceed 20-amps or the 100-volt rating of the solar controller.

The awning manufacturer provides a complete Owner/Operator Manual for the awning located in your owner’s packet. The multiplex panels control the awning’s extend/retract feature as well as the awning lights.

The awning must be retracted before driving the Touring Coach. Damage may occur if the awning is not properly retracted. The awning will not extend while the vehicle’s engine is running.

Rear doors must be closed when operating the awning or if the vehicle is left unattended, due to a seismic sensor, with the awning extended. Damage may occur if the awning is extended or retracted with the rear doors open.

Awning Use In Wind and Rain
The automatic extra strong awning comes with a Direct Response™ System seismic sensor. The Direct Response™ System is an innovative seismic sensor system that automatically activates the 12V motor and retracts the awning in strong winds, thus avoiding possible damage to the awning.

If wind or extended periods of rain are expected, retract the awning and secure as for travel. The effects of wind and rain on any awning are unpredictable. Severe damage to the vehicle and or the awning may result and cannot be covered by warranty.

Never use the awning with damaged fabric. Make sure the awning can be correctly retracted.

Awning Manual Override
If the power to the vehicle is not available, the awning can be safely retracted using the manual override located on the idler (right) end of the case. A ratchet and socket extension has been included and is located under the passenger side compartment floor.Airstream Touring Coach Interstate 19 2023 Solar Ports User Manual 01

  1. Remove the thumb screw from the backside of the decorative awning cap. The cap will be held in place by Velcro which must be released before removing.
  2. Remove the cover from the right end of the awning and save.
  3. Insert the 3/8” socket drive extension and handle into the square drive hole inside the end cap.
  4. Turn the handle clockwise until the awning is retracted.
  5. Replace the end cap.

After closing the awning with the manual override, the lead rail may move out from the case 1/4”-1/2”. This is normal and the awning is secure for travel until power is restored or repairs are completed. Do NOT attempt to force the lead rail in with the override, serious damage can occur to the awning.

Airstream Touring Coach Interstate 19 2023 Changing Tire User Manual

How to Change Tire: 2023 Airstream Touring Coach Interstate 19

Changing A Tire

(Partially excerpted from the Mercedes-Benz Sprinter Van Operator’s Manual)
After changing a wheel, the wheel nuts must be tightened once the vehicle has been driven for about 30 miles.
If new or repainted wheels are fitted, the wheel nuts must be retightened again after about 600 to 3000 miles. Do not use remolded tires.

Fitting wheel sizes other than those supplied by Sprinter to the vehicle will change the Sprinter’s handling characteristics and may lead to an accident resulting in severe personal injuries, death and property damage.

Read the Sprinter manual for wheel torque and wheel tightening procedures.

The Mercedes-Benz Sprinter Operator’s Manual contains important cautions, warnings, specifications, and operational information on changing, maintaining, and replacing of the tires and wheels. Read, understand, and follow the Sprinter manual sections for changing a tire.

Changing a tire on a touring coach chassis is a physically demanding procedure. It requires specialized tools and knowledge of safety procedures. Only you can determine your knowledge base and physical ability. Don’t take any unnecessary risks. Find a safe area to park your unit, and call a tire service center and supply them with the information in the Sprinter Manual if you have any doubts about changing a tire.

Flat Tire
If you get a flat tire while driving, gradually decrease your speed. Hold the steering wheel firmly and slowly move to a safe place on the side of the road. The pressure of the spare wheel (sold separately) should be checked regularly (at least after every tenth time at the filling station). The vehicle tool kit is located in a hatch under the front passenger foot well.

Use a jack (sold separately) designed exclusively for jacking up the vehicle at the jack take-up brackets built into either side of the vehicle. To help avoid personal injury, use a jack only to lift the vehicle during a wheel change. Never get beneath the vehicle while it is supported by a jack.

Precautions When Changing a Wheel

  • Keep hands and feet away from the area under the lifted vehicle.
  • Always firmly set the parking brake and block wheels before raising the vehicle with the jack.
  • Do not disengage the parking brake while the vehicle is raised.
  • Always use the jack on a level surface.
  • Do not jack the vehicle up more than 1-2 in. between the tire and the surface. Otherwise, the vehicle may tip over and may cause serious injury or death to you or others.
  • Be sure that the jack arm is fully seated in the jack take-up bracket.
  • Always lower the vehicle onto the sufficient capacity jack stands before working under the vehicle.
  • Do not damage, grease, or oil wheel nuts or stud threads.


  • Park the vehicle on a firm, level, non-slippery surface.
  • Switch on the hazard warning flasher switch, apply the parking brake, and place the transmission selector in “P”.
  • Everyone must leave the vehicle before you jack it up.
  • Everyone must leave the danger zone before you jack up the vehicle. Danger zones vary with location. Take a minute and look at what might happen if the vehicle falls off the jack and rolls. Set up your danger zone.
  • The vehicle must be safeguarded in accordance with legal regulations (such as using a warning triangle).
  • Prevent the vehicle from rolling away by blocking wheels with wheel chocks (not supplied with the vehicle) or sizable woodblocks or stones. On a level road place one chock in front of and one behind the wheel that is diagonally opposite to the wheel being changed. When changing a wheel on mild uphill or downhill grade, place chocks on the downhill side blocking both wheels of the other axle. Do not jack the vehicle up on a steep grade.

Airstream Touring Coach Interstate 19 2023 Loading User Manual

2023 Airstream Touring Coach Interstate 19 Loading User Manual


One of the most critical aspects of safely operating a touring coach is knowing the weight involved and where it is placed. The first thing to determine is how much cargo is being loaded and confirming that it is within the capacity of the equipment being used. Determining WHERE that load is placed is critical to the way your rig will handle on the road. Do not try to guess what your touring coach weighs loaded. Load your touring coach including water, propane, etc and take it to a public scale. Weigh each axle of your vehicle. Refer to your axle weight and tire limits to see if you are within a safe range. Total all axle weights and make sure you are below the GVWR. If you are not overloaded, make sure your load is balanced. Do not load too much on one side. A balanced load is much easier to tow or drive. Front to back balance is also important. Step back and look at your touring coach. Make sure there is not too much weight in the front or on the rear of the touring coach. Be sure to secure all items. Loose items can cause damage and can be a safety issue. The Cargo Carrying capacity tag shown below is installed on every touring coach and can be found on the inside of the door on your vehicle.


A full load of water equals XXX kg or XXX l bs of cargo @ 1 kg/L (8.3 lb/gal) and the tongue weight of a towed trailer counts as cargo To arrive at “THE COMBINED WEIGHT OF OCCUPANTS AND CARGO SHOULD NEVER EXCEED” number, Airstream weighs the vehicle as finished and adds the weight of full tanks of LP and chassis fuel.

That number is subtracted from the GVWR of the touring coach and listed on the tag, The total weight of any and all cargo, including but not limited to dealer or customer modifications or additions, fluids (fresh water and holding tanks), food, clothes, tools, tongue weight of a towed trailer or vehicle, and passengers should never exceed the number listed while the touring coach is in transit. The “SAFETY BELT SEATING CAPACITY” is the number of passengers that seat belts are provided for. The “A FULL LOAD OF WATER EQUALS” number is arrived at by multiplying the fresh water tank and water heater capacities by 1Kg/L or 8.34 lb/gal.

When loading the vehicle it is important to keep
the GVWR, GAWR, Tire Weight Ratings (listed on the vehicle tire Information placard), and the cargo and occupant capacity in mind and not to exceed these specifications. Your safety depends on not overloading the touring coach, axles, and tires. See the specification section for the weight rating list of these items.

To determine the actual weight of your vehicle with personal cargo and water, it must be weighed on scales as you plan to travel. The most common scales are those used by states to weigh trucks along the highway. In rural areas, grain elevators, cement outlets and gravel pits are a good source.

Weighing instructions for this touring coach are explained on the next page. If you have trouble locating scales, a call to your State Highway Patrol will usually find them cooperative in assisting you. Vehicle and Trailer Weights and Rating Definitions Gross Vehicle Weight Rating (GVWR) is the maximum permissible weight of the touring coach. Gross Vehicle Weight (GVW) comprises weight of vehicle including tools, installed accessories, passengers, cargo, and trailer tongue weight. It must never exceed the GVWR. Gross Axle Weight Rating (GAWR) is the maximum permissible axle weight. Gross Trailer Weight (GTW) is the maximum permissible trailer weight to be towed. Trailer Tongue Weight Rating (TWR) is the maximum permissible weight of the trailer tongue. This counts as cargo when loading a touring coach.

Check the Sprinter manual for all weights and the tire information placard location.

Trailer Towing and Driving

(Some text is partially excerpted from Mercedes-Benz Sprinter Operators Manual.)

Failure to use proper equipment and driving technique can result in a loss of vehicle control when towing a trailer. Improper towing or failure to follow the instructions contained in this section can result in serious injury. Follow the guidelines below carefully to assure safe trailer operation. Ask your authorized Mercedes-Benz Sprinter or Airstream dealer if you require an explanation of information contained in the manuals.

Trailer Hitches
Units have hitches and wiring installed from the Mercedes-Benz manufacturer. The Sprinter 7- way connector is used for lights and charge line on a trailer. For further information, please see your authorized Mercedes-Benz Sprinter dealer. To reduce the possibility of damage, remove the hitch ball adapter from the receiver when not in use. Since this vehicle is designed and intended primarily as a load-carrying vehicle, towing a trailer will affect handling, durability and economy. Maximum safety and satisfaction depends upon proper use of correct equipment and avoiding overloads and other abusive operation.

The total weight of the touring coach and trailer must not exceed the GCWR listed in the specification section of this manual. The maximum towing capacity varies according to the size of the touring coach and its GCWR. Vehicles should be properly equipped for towing trailers. Information on trailer hauling capabilities and special equipment required may be obtained from your Mercedes-Benz Sprinter and/or Airstream dealer.

Loading a Trailer
When loading a trailer, you should ensure neither the permissible GTW (Gross Tongue Weight), nor the trailer GVWR are exceeded.
Maximum permissible values are listed on the safety compliance certification labels for the vehicle and for the trailer to be towed. For their location, see the Mercedes-Benz Sprinter Operator’s Manual. The lowest value listed must be selected when determining how the vehicle and trailer are loaded. To assist in attaining good handling of the vehicle/trailer combination, it is important that the tongue weight be maintained at approximately 10-15 percent of the loaded trailer weight, but not to exceed the hitch rating. Tongue loads can be adjusted by proper distribution of the load in the trailer, and can be checked by weighing separately the loaded trailer and then the tongue. The tongue weight at the hitch ball must be added to the GVW to prevent exceeding your Sprinter towed vehicle’s rear GAWR. When towing trailers, touring coach tires should be inflated to the highest pressures shown on the Sprinter Tire Information Placard. See Mercedes-Benz Sprinter Operator’s Manual for its location. The Cargo Carrying Capacity (CCC) of this vehicle is reduced by the amount that equals the trailer tongue load on the trailer hitch.

Checking Weights of Vehicle and Trailer
To assure that the tow vehicle and trailer comply with the maximum permissible weight limits and to know the actual weights, have the loaded vehicle-trailer combination (tow vehicle including driver, passengers, cargo, and trailer fully loaded) weighed on a commercial scale as explained earlier in this section. Also, check the vehicle’s front and rear axle weights and tongue weight. The values as measured must not exceed the Sprinter weight ratings listed on vehicle information placards and in the Mercedes-Benz Sprinter manual. These ratings are also listed in section 4 – Floor Plans, Specification Chart of this manual.

Check the Mercedes-Benz Sprinter manual for all weights and tire information placard locations.

Attaching a Trailer
Please observe the maximum permitted trailer dimensions (weight and length). Most states and all Canadian provinces require safety chains between your tow vehicle and trailer. The chains should be crisscrossed under the trailer tongue. They must be attached to the hitch receiver and not to the vehicle’s bumper or axle. Be sure to leave enough slack in the chains to permit turning corners. Most states and all Canadian provinces required a separate brake system for towing trailers.

The towing vehicle’s braking system is rated for operation at GVWR, NOT at the GCWR. A separate, functioning brake system is required for any towed vehicles or trailers weighing more than 1000 lb (450 kg) when fully loaded. NEVER exceed the GVWR or the GAWR specified on a touring coach certification label. Also, NEVER exceed the weight ratings of a trailer hitch installed on a touring coach. Failure to heed any part of this warning could result in loss of control of the touring coach and towed vehicle or trailer which may cause an accident and serious injury. For specified towed vehicle braking requirements, consult the Mercedes-Benz Sprinter Operator’s Manual that comes with this vehicle.

Do not connect a trailer brake system (if the trailer is so equipped) directly to the vehicle’s hydraulic brake system if your vehicle is equipped with anti-lock brakes. If you do, neither the vehicle’s brakes nor the trailer’s brakes will function properly. Property damage, injury, or death to you or others may be the result. The provided vehicle electrical wiring harness for trailer towing has a brake signal wire for hookup to a brake controller. Most states and all Canadian provinces require a breakaway switch on trailers with a separate brake system. The switch activates the trailer brakes in the possible event that the trailer might separate from the tow vehicle. Please consider using a trailer sway control system. For further information, see your authorized Mercedes-Benz Sprinter or Airstream dealer.

Towing a Trailer
There are many different laws, including speed limit restrictions, having to do with trailer towing. Make sure that your vehicle-trailer combination will be legal not only for where you reside but also for where you’ll be driving. A good source for this information can be the State Attorney General, State Police, or local authorities. Before you start driving with a trailer, check the trailer’s hitch, breakaway switch, safety chains, electrical connections, lighting, and tires. Also, adjust the mirrors to permit an unobstructed view beyond the rear of the trailer. If the trailer has brakes using an electric brake controller, start your vehicle and trailer moving slowly, and then apply the brakes manually using the brake controller to be sure the brakes are working properly. Read and follow the controller manufacturer’s recommendations. When towing a trailer, check occasionally to be sure the load is secure, and lighting and trailer brakes (if so equipped) are functioning properly. Always secure items in the trailer to prevent load shifts while driving. Take into consideration that when towing a trailer, the handling characteristics are different and less stable than those when operating the vehicle without a trailer. It is important to avoid sudden maneuvers. The vehicle and trailer combination is heavier, and therefore is limited in acceleration ability and requires longer stopping distances. It is more prone to reacting to side wind gusts and requires more sensitive steering input. In order to gain skill and an understanding of the vehicle’s behavior, you should practice turning, stopping, and backing up in an area that is free from traffic. If possible, do not brake abruptly, but rather engage the brake slightly at first to permit the trailer to activate its brake. Then increase the braking force. We want every owner to be a safe and courteous driver. A few hours of towing practice in a large empty parking lot will make pulling your trailer over the road much easier. Line out two corners for left and right turns. You may also use these corners to practice backing and parking.

2023 Airstream Touring Coach Interstate 19 Inspection and Storage User Manual

Tire Inspection and Storage

Before taking your touring coach on a trip or when removing it from an extended storage period, make it a practice to inspect the overall condition of your tires. Check for any type of condition or damage that might result in failure. A thorough check should include both inside and outside sidewalls, tread area, and the condition of hardware such as valve stems, valve caps, and wheels. The tread should be checked for any unusual wear, cracking, penetrations, and/or cuts. An uneven wear pattern can indicate misalignment or worn suspension parts. Since many touring coach’s are used seasonally and sometimes stored for extended times, it is possible that tires will take many years to wear out. Tires, as any rubber product, will age over time. If tires show cracking in the sidewall or tread surfaces that are more than 2/32-in. deep, they should be replaced before your next trip or vacation. Store your touring coach in a cool, dry area away from major heat sources and extreme cold. An enclosed storage area is best with no exposure to electromagnetic sources such as generators or transformers. If you must keep your touring coach outside, cover your tires from direct sunlight. Take your touring coach to your tire dealer for service to check or correct any of these conditions.

California Tire Chain notice: Your motorhome may not be operated with tire chains.

For safety reasons, the wheel tightening torque must be checked immediately after changing a tire and again after 30 miles to 140 ft-lbs. The wheels could otherwise come loose.

Lithium Iron Phosphate Batteries (House Batteries)Airstream Touring Coach Interstate 19 2023 Tire Inspection and Storage User Manual 01

Your Airstream Touring Coach is factory-equipped with two 100Ah 12V LiFePO4 deep-cycle batteries. The house batteries are located under the coach behind the driver’s and passenger’s step well.

Lithium Technology
Airstream’s lithium batteries require no new hardware, or complicated setup, and are a drop-in upgrade. They are designed to outperform traditional lead acid batteries and offer more usable energy. Lithium batteries have a life span of approximately 3000-5000 cycles. A cycle is determined by a discharge and a charge. How many cycles a lithium battery can sustain is determined by how depleted a battery is discharged, before it is charged. A battery that is only discharged 50% will have more cycles than a battery that is constantly discharged to 0%. Lithium batteries provide longer life and faster charging than lead acid batteries, while still providing 80% of the rated capacity, after thousands of cycles. If the batteries are completely depleted, it will take approximately 8 hours to charge the 200Ah battery bank, at 25 amps. Unlike lead-acid batteries, which require water replacement, lithium batteries require no active maintenance. The use of lithium batteries in Airstream’s Touring Coach also provides the benefit of delivering more energy at typically half the weight of a traditional battery.

An owner’s manual for lithium batteries is provided in the Airstream Owner’s Packet. Make sure to read, understand, and follow all information, such as Notes, Cautions, and Warnings, before operating.

Battery Management System (BMS)
A BMS is crucial in ensuring safe operation of any lithium battery. The BMS monitors cell voltages, currents, and temperatures to make sure they are operating in a safe range. The BMS is sealed internally and will shut the battery down should any fault condition occur. The battery will restart once the fault condition is cleared.

The following, are features of the BMS:

  • Over/under voltage protection
  • High current protection/short circuit
  • High-temperature protection
  • Low-temperature charging protection
  • Cell balancing

Even though the BMS will protect against issues from overcharging, it should be avoided. The recommended specs are 14.4-14.6 bulk/absorb and below 13.6 floats. The BMS will shut the batteries down when the battery voltage drops below approximately 11.5 VDC. When the batteries shut down, due to Low.

Battery Cut Off
(LBCO), both the main battery disconnect switch and the inverter power switch will remain in the positions they were in, prior to the batteries shutting down. To bring the batteries out of LBCO Mode, a voltage of approximately 11 VDC or greater needs to be applied across the battery terminals. There are two ways of doing this:

  1. Start and run the vehicle engine. This will provide an alternator voltage of approximately 14.5 VDC across the battery terminals and provide a charge current through the DC-DC converter. The DC-DC converter will limit the charge current to the house batteries to approximately 40 amps. This should take approximately 1 minute.2
  2. Jump the house batteries with an external battery charger (only one battery will need to be jumped).

When the inverter/charger display turns on, the vehicle’s engine can be turned off, if the coach is plugged in or the generator is started. Otherwise, the engine will need to be run long enough to fully charge the house batteries. If the coach is not plugged into shore or generator power, to charge the house batteries, the batteries can go back into LBCO Mode soon after the vehicle’s engine is turned off. Bringing the batteries out of LBCO Mode is only “waking up” the batteries and allowing them to take a charge. If wanting to use the generator to charge, the vehicle’s engine will need to be ran for several minutes before the house batteries are charged enough to start the generator.

If the batteries are in LBCO Mode and it is below 35°F, turn the “Battery Heater” switch to “ON” before performing the wake up procedure.

The BMS will not allow a charging current if the internal temperature is below 25°F and it will not allow a charging or discharging current above 135°F.

Battery State of Charge
The heated batteries consume an average of 1.8 amps. Testing indicates, that at 0°F, with no insulation, the heater would be on about 30% of the time. With no other loads or charging, the batteries would give approximately 185 hours of heat capability before the batteries would go into LBCO shutdown.

Airstream Touring Coach Interstate 19 2023 LPG User Manual

2023 Airstream Touring Coach Interstate 19 LPG User Manual

LPG System

Your touring coach is equipped with a permanently-mounted tank for LPG with a remote fill and remote gas supply shut off switch. LPG burns with a clean blue flame. LPG is used where subfreezing temperatures are common since it boils at -44°F. Keep in mind at these temperatures the BTU is lower than at 30°F. How long a full tank of gas will last is dependent on usage. In cold weather, when you are using the furnace, using large amounts of hot water, or cooking extensively, you will naturally use more LPG than you will in warm weather, or when doing limited cooking. On average, with normal cooking and other appliance use, you can probably count a few weeks of usage from the tank, if you are not running your generator. If you have allowed the tank to run out, air may have gotten into the lines. In this event, the air must be allowed to bleed from the lines before lighting appliances. Follow the appliance manufacturer’s instructions and light the appliance closest to the LPG supply tank. Then move to the next closest, etc.

LPG Tank Remote Fill
The LPG tank is filled by accessing the remote fill hookup located in the compartment under the passenger side rear fender behind the rear wheels. Be sure the fill is free of dirt. It may help to remind your LPG supplier to only use a clean fill hose to fill your tank. Turn off the remote switch when the LPG system is not in use, as it draws a 12-volt current from the batteries.

Only certified LPG suppliers should fill the LPG tank. Turn the remote gas supply switch off before filling or refilling LPG tank.

Always shut off the LPG gas when refueling the touring coach.

Remote Gas Supply SwitchAirstream Touring Coach Interstate 19 2023 LPG System User Manual 01

A remote switch for shutting off the gas to all appliances is located in the rear passenger’s side compartment. The switch activates an electric solenoid which opens and closes, shutting the gas off at the tank. This switch should be turned off during the filling of the LPG tank or when LP is not needed to fuel appliances. Gas lines should be checked periodically for leaks with ammonia-free soapy water.

Be careful when working around electricity, as it can carry dangerous amperage and cause sparks or combustion.

The electric gas shut-off solenoid closes automatically when 12-volt power is disconnected. It will reopen when power is restored.

All LP gas appliances must be turned off during refueling of the touring coach fuel tank and permanently-mounted LPG tank.

Do not use an open flame to search for problems. If gas can be smelled, appliance pilots fail to stay on, or any other abnormal situation occurs, use the remote supply switch to shut off the tank valve immediately and call on a qualified LPG service center or Airstream Service Center.

LPG Regulator
The LPG regulators used on Airstream Touring Coach are designed for low-pressure service, with a normal outlet pressure setting of 11”-14” water column. Only personnel trained in the proper procedures, codes, standards, etc., should service regulators. Has the regulator inspected each time the tank is refilled? Replace any regulator that has had water in the spring case, or shows evidence of external corrosion or corrosion inside the spring case.

Moisture in the LPG tank will cause a malfunction of the regulator in controlling proper pressure. This may result in the flame lifting off the burner or going out frequently. Many refueling stations will add approximately ¼ to ½ gal of alcohol allowing moisture to pass through the regulator without the formation of ice crystals.

Exterior LP Port
A quick-connect, low-pressure LPG connection is located under the passenger side rear quarter panel behind the dual wheels. It is a utility connection to use for an outside grill or other LPG appliance. Check that the remote LPG shut-off switch is turned off. Slide the collar on the female end back and plug the male hose into the connection. Release the collar and check that the hose is properly connected by giving a firm pull on the hose. Turn the LPG remote shut-off switch on and recheck all connections to the appliances and quick connection to be sure no leaks are present. Follow all instructions, cautions, and warnings in this manual when connecting and disconnecting appliances.


Water System (Self-Contained)
The freshwater system consists of a city water hookup, fresh water tank gravity fill, fresh water tank and drain valve, water pump, hot and cold water lines, water heater, fresh water line low point drain valves, and faucets. Full explanations on the locations and use of these features are explained in this section. Before using the water system, check that the water heaters drain valve is closed. See Winterizing and Storage for further information on the drain valve. Close all low point drain valves and the fresh water tank drain valve.

Fill the water tank by opening the main sliding door to access the gravity feed water fill cap. A high-pressure RV/Marine FDA approved drinking water hose of at least ½-in. diameter made from material that is tasteless, odorless, and non-toxic can now be inserted. It’s a good idea to let the water run through a hose for a short time to flush it out. Reveres sometimes fill their tanks with “home” water to avoid strange water that may be distasteful to them on short outings. Remember, the more water you carry in the Fresh Water tank, the less cargo carrying capacity you have for other items. The amount of water in the tank may be checked on the Multiplex Control Panel. Keep watch of the water level as the water fill is essentially on the interior of the unit. Open the hot side of the galley faucet and turn on the water pump switch located on the monitor panel. For some time, the open faucet may only sputter.

This is because the water heater is being filled and air is being pushed out through the lines. Once the water heater is full, a steady stream of water will flow from the faucet. Now, open a cold faucet. It may sputter for a short time, but will soon expel a steady stream. All other faucets can now be opened until all air is expelled. Once the system is filled with water and the faucets closed, the water pump will shut off. When a faucet is opened, the pump will come back on automatically. If the faucet is just barely open, it is normal for the pump to cycle on and off rapidly. It is normal for a pump to occasionally cycle when all faucets are off to keep the water pressure at the set point. However, if it cycles frequently (e.g. more than a few times an hour) the plumbing system, pump, and pump strainer should be checked to be sure it is not losing pressure through a slow water leak or back through the pump.

To prevent equipment damage, the water heater should only be started after the water system is primed and ready for use.

Turn the water pump off when the touring coach is left unattended or in motion.

Airstream Touring Coach Interstate 19 2023 Drain and Waste User Manual

Drain Waste System: 2023 Airstream Touring Coach Interstate 19

Drain and Waste System

Your touring coach has a drain and waste system that includes waste-holding tanks made from corrosion-free, molded plastic, with trouble-free dump valves. The main (Black Water) holding tank enables you to use the toilet for several days away from disposal facilities. The waste water from the sink, shower, bath, and lavatory drains into the auxiliary (Gray Water) holding tank. Each tank has its own dump valve with both tanks draining through a common outlet. Therefore, only one sewer hose connection is needed when hooking up to a dump station. Almost all campgrounds will have dumping facilities. Park directories, such as Woodall’s and Rand McNally, also list dumping stations. Furthermore, the navigation system’s GPS can be used to locate nearby dumping stations or highlight stations along your route. Check the levels on your multiplex screen regularly. When the Black Water holding tank is completely full, sewage cannot be emptied from the toilet bowl. If the Gray Water holding tank is overfilled, drain water will back up into the shower floor pan and cause an unpleasant cleaning job. Never drain the tanks at any place other than an approved dumping station.

Never put wet-strength paper towels or tissues in your holding tank since they will not dissolve and can catch in the mechanism of the dump valve. Colored toilet tissue is slower to dissolve than white. Most motorhome accessory stores offer tissue designed for RVs that will completely dissolve.

Macerator Pump
The waste pump is the ideal solution for emptying holding tanks on touring coaches. The macerator section grinds waste down to a particle size of 1/8-in. maximum. The waste pump will macerate and pump all waste and tissue normally found in recreational vehicle waste systems.

The waste hose is pressurized when operating the macerator pump. Secure the loose hose end at the disposal facility with a supplied inlet adaptor before turning on pump. The high-pressure waste hose is stored on an electric hose reel and connected to the Discharge Port Adaptor. It has a threaded, drip-proof valve with a versatile, two-size, threaded adaptor allowing the valve to be connected to 3 sizes of threaded inlets, including an exterior home sewer clean-out. The adaptor snaps over the valve threads.

A rubber ring is also provided to lodge into a non-threaded inlet. If the rubber ring seems loose when used, Airstream recommends using some type of weight to further secure the hose. Each holding tank, the macerator pump, and the macerator pump electric hose reel have individual switches which are located in the roadside utility compartment. Each valve switch has a light that illuminates to let you know the valve is opened. Pressing a dump valve switch and holding it for 2-3 seconds until it is lit opens a holding tank valve. Pressing it again for 2-3 seconds closes it. The macerator pump has an ON/OFF toggle switch. The reel has a switch for releasing and retracting the hose, once the hose is released it is deployed manually by pulling the hose out. To retract the hose, press and hold the retract button while guiding the hose back and forth onto the reel evenly.

Do not run Macerator pump more than 15 minutes continuously. Do not run the Macerator pump dry for more than 30 seconds. THE MACERATOR WILL NOT HANDLE HARD SOLID OBJECTS, SANITARY NAPKINS OR RAGS. Never put wet strength paper towels, tissues, or sanitary napkins in your holding tank. They will not dissolve and will jam the mechanism of the dump valve and the macerator pump impeller.

Emptying the Black and Gray Water Holding Tanks
Airstream Touring Coach Interstate 19 2023 Drain and Waste System User Manual 01

  1. Remove the high pressure waste hose by opening the hose reel compartment door and momentarily pressing the “release” switch. Once released, the hose can be manually pulled out. Secure the hose at the disposal facility inlet using the threaded or rubber adaptor and open the drip proof valve on the end of the hose.
    The pressure from the macerator pump may push the hose from the inlet if the hose is not secured properly.
  2. Open the Black Water valve. Empty the Black Water tank first and the Gray Water tank second, using the Gray Water to help flush the pump and hose of Black Water sewage.
  3. Turn on macerator pump to liquefy and pump out the solids in the tank.
  4. When black tank is empty, turn off the pump.
  5. Open the Gray Water tank valve and turn on the pump. Run until just before the pump runs dry. Any trickle of gray water left will remain in discharge hose behind drip proof valve and is typical. Remember, running the pump dry for more than 30 seconds could damage the pump.
  6. Turn the drip-proof valve off and remove the hose adaptor from the dump station inlet. Retract the hose into the hose reel by holding the switch in the “retract” position. Be sure to guide the hose back and forth onto the reel evenly. Close the compartment door.
    Watch all connections while dumping. Close the dump valve immediately, turn off pump, and close hose drip-proof valve if a leak is noticed.

Macerator Impeller Release FeatureAirstream Touring Coach Interstate 19 2023 Drain and Waste System User Manual 02

After long periods of non-use, a stuck impeller can be easily broken loose with a screwdriver inserted in the motor shaft slot. Remove the rubber boot, turn the shaft clockwise, and replace the rubber boot. The impeller can usually be found under the touring coach, near the macerator hose reel.

Manual Operation
In case the electric dump valves fail to open, manually pull/push the arm once, to open and close the valve. The manual arm is located under the vehicle, near the macerator hose reel.Airstream Touring Coach Interstate 19 2023 Drain and Waste System User Manual 03

Airstream Touring Coach Interstate 19 2023 Drain and Waste System User Manual 04

Extended Stays
When you are in a park with a disposal facility, empty the tanks every few days or whenever they become almost full. Pumping a large volume of liquid through the tanks at a time will keep toilet paper and other solids completely washed away. Remember to empty the Black Water tank first and then the Gray Water tank using the Gray Water to flush the system. This practice will avoid the accumulation of solids in the tank, which could lead to an unpleasant cleaning job. Should solids accumulate, fill the tank about half full with water using the black tank flush inlet, and then drive the touring coach for a few miles. Don’t wait until the tank is packed solid. The turbulence and surging of the water will usually dissolve the solids into a suspension so the tank can be drained. Draining the tanks as described will protect them from freezing during storage.

Macerator Pump Winterizing

Plan your winterizing and storage ahead, and be sure the holding tanks are drained and flushed thoroughly. This is very important, as the frozen sewage and water could seriously damage the system. After dumping the tanks, add RV, non-toxic antifreeze to one of the holding tanks and start the macerator pump. Run the pump until the RV, non-toxic antifreeze comes out the end of the pump hose, then close the dump valve. As an extra protection, open the toilet valve and add RV, non-toxic antifreeze through the toilet into the Black Water tank and pour RV, non-toxic antifreeze into a sink drain to protect the holding tanks, valves, and pump from residual water freezing.

Restoring Service

  1. Re-install the fully charged house batteries.
  2. Close the low point drain valves, holding tank dump valve, water faucets, and freshwater tank drain.
  3. Reconnect the water pump line.
  4. Add water to the freshwater tank.
  5. Turn the water pump on.
  6. Open and close faucet valves one at a time until the water runs clear at all faucets signaling the RV, and non-toxic antifreeze is flushed out of lines. Go back and recheck water clarity at all faucets.
  7. Turn off the water pump.
  8. Hook up city water, open faucet valves, and recheck water clarity.
  9. Close the water heater drain valve and reset the water heater valve to its normal operating position.


Toilet Winterizing
Draining Method: Turn off the touring coach’s water supply. Drain the toilet bowl. Disconnect the supply line at the water valve. Completely drain the toilet’s water supply line.
Antifreeze Method: Use RV, non-toxic antifreeze only.

To avoid damage when using air pressure to blow water from the lines, make sure the toilet valve is in the open position.

If water is frozen in the toilet, do not attempt to flush until the ice thaws. Never use automotive-type antifreeze.

If the bowl-sealing blade does not operate freely after extended use, it may be restored to its original, smooth operating condition by applying a light film of silicone spray to the blade. To clean the toilet use Thetford Aqua Bowl or any other high-grade, non-abrasive cleaner. Do not use highly concentrated or high acid-content household cleaners. They may damage the rubber seals.


  1. Leaks:
    • Back of toilet: check the water supply line connection at the water valve. Secure or tighten as necessary. If the leak persists from the water valve, replace.
    • Vacuum breaker leaks while flushing: replace the vacuum breaker or water module, depending on the model.
    • Between closet flange and toilet: check flange nuts for tightness. If the leak continues, remove the toilet and check the flange height. Use Thetford spacers to adjust, if necessary, to 7/16-in. above floor. Replace the flange seal.
  2. The toilet won’t hold water:
    • Check for and remove any debris from the blade ball seal track.
    • Check the blade/ball seal compression mechanism. If the blade/ball seal is worn, replace it.
  3. Harder than normal pedal operation: Apply a light film of Thetford Toilet Seal Lubricant & Conditioner or silicone spray to the blade/ball.
    (Note: To avoid damage, do not use spray lubricants other than silicone.)
  4. Poor flush: The pedal must be held completely down to flush. A good flush should be obtained within 2 to 3 seconds. If the problem persists, remove the water supply line and check the flow rate.
