Vehicle Operation

2023 RV owner’s guide

Your motor home will travel safely and comfortably at highway speed limits. However, it will take longer than a passenger automobile to reach that speed. Allow more time to go around the vehicle you are passing. Avoid situations that might require sudden momentum changes as the length of the motor home affects your ability to quickly cut back into traf-fic. Swerves and sharp turns, especially at high speeds, could result in loss of control of the motor home.
The motor home has a longer turning radius. When turning, check the road clearance and be aware of others, especially if towing a vehicle behind your motor home.
Adverse weather conditions and extremes in terrain may affect the performance and handling of your vehicle. Do not operate the cruise control on icy or extremely wet roads, gravel roads, winding roads, in heavy traffic, or in any other traffic situation where a constant speed cannot be maintained. Use care when accelerating or decelerating on a slippery surface. Abrupt speed changes can cause skidding and loss of control.


Braking and Stopping
Even though your motor home is equipped with brakes designed for its Gross Vehicle Weight Rating (GVWR) we suggest you practice stopping away from traffic until you become accustomed to your motor home’s stopping distance. Your motor home is equipped with a third brake light that activates when the brakes are engaged.
When descending a long hill, shift the transmission into a lower gear and engage the auxiliary engine braking. If your motor home is equipped with an auxiliary engine brake, engagement is activated by a switch on the driver’s console. See the chassis owner’s manual for additional information. The transmission and engine will help in controlling downhill speed and can lengthen brake life. The distance required to stop the motor home is greater than automobiles.
Driving through water deep enough to wet the brakes may affect stopping distance or cause the vehicle to pull to one side. Check the motor home’s brake operation in a safe area to be sure they have not been affected. Never operate any vehicle if a difference in braking efficiency is noticeable.

Parking Brake
The parking brake should be engaged when the motor home is parked. Never drive your motor home with the parking brake engaged as this will reduce braking effectiveness and cause excessive driveline wear. Refer to your Chassis guide for more information on the parking brake.

Towing Behind Your Motor Home

Towing will affect vehicle handling, durability and fuel economy. Exceeding any of the listed weight ratings will result in unacceptable overall vehicle performance. Your safety and satisfaction require proper use of correct equipment.

For maximum pulling load and vertical tongue weight, refer to the label located on the rear hitch. A hitch bar of appropriate strength and steel should be selected to meet the capacities of the towing receptor.
Always use safety chains between the motor home and the towed trailer or vehicle. Cross the chains under the tongue and allow for slack when turning corners. Connect the safety chains to the vehicle frame or hook retainers. Never attach the safety chains to the bumper.
Before descending a steep or long grade when towing a trailer or vehicle, reduce speed and shift the motor home into a lower gear to control vehicle speed. Avoid frequent or prolonged brake application, which can cause overheating or brake failure.
By definition, the GCWR is “the maximum total weight rating allowed for a vehicle and any attachment, such as a trailer or towed vehicle. To determine the total allowable weight for a towed item, subtract the GVWR from the GCWR.


  • Total weight of your motor home and any trailer or vehicle towed by it must not exceed the GCWR. Do not assume that you can tow a vehicle that happens to be within the capacity of the hitch. By doing so, you may exceed the total GCWR of the motor home.
  • The total weight of your motor home (including cargo, passengers, fluids, etc.) in addition to the vertical (tongue) weight must not exceed the GVWR and/or any GAWR. Once again, do not assume that you can tow a trailer or vehicle that happens to be within the vertical (tongue) weight capacity of the hitch. By doing so, you may exceed the GVWR and/or GAWR of the motor home.
  • Your motor home chassis braking system is rated for operation at GVWR, NOT GCWR. Any trailer or vehicle being towed by your motor home must have adequate brakes as required by all state (or province) and local regulations for towing with your motor home, including areas you may be travelling through. Failure to follow the towing guidelines may result in property damage or injury.

In addition, a separate supplemental braking system must be installed if the towed trailer or vehicle meets or exceeds the minimum weight determined by the chassis manufacturer (this minimum weight rating will vary by chassis and chassis manufacturer).
Contact your dealer for assistance in determining whether a separate braking system is recommended for your towing and travelling safety. Failure to follow these instructions will create a safety hazard and may result in an accident.

Keep the hitch clean along with your general frame maintenance.

  • At the beginning of the season, and monthly or thereafter, clean the inside of the receiver tube with a wire brush and spray with a silicone spray.
  • Always remove the utility mount from the receiver when it is not in use. This will help prevent the utility mount from rusting to the tube.
  • Periodically check the bolts for tightness. They need to be torqued to the proper setting (refer to your Chassis Guide).

Power Entrance Step

The electric doorstep opens automatically when the screen door is opened. Constant 12-volt power to the electric step is supplied through a circuit breaker.


  • When opening the door from the outside, make sure you are not obstructing the path of the entrance step. Step deployment takes approximately two seconds. Keep hands and fingers clear while extending or retracting.
  • Look before you exit. Make sure the steps are fully deployed before exiting the motor home. Stepping on a partially extended step can cause damage to the step frame.

Entrance Door

Always hold onto the entrance door when opening or closing it. Damage caused because you failed to do so is not covered by the Limited Warranty.

Make sure the entrance door is completely closed and locked when travelling. Locking the door helps prevent it from opening unintentionally and keeps intruders from your recreation vehicle.

The entrance screen door may be equipped with a slide panel that allows access to the entrance door handle and locks. The entrance door may also be equipped with both a regular door lock and a deadbolt lock.

Several keys are provided when you purchase your vehicle. Most keys have an individual key number stamped on the plate. Record these key numbers and keep the information in a safe place. You can order a key blank from your dealer to have duplicate keys made. If you lose the keys, contact your dealer or a locksmith for assistance.

Locks on entrance and baggage doors need biannual lubrication using a light coat of silicone spray. Conditions such as rain, salt, dust and pollution may increase the maintenance needs.

2023 Jayco Precept Prestige Fuel System

Exhaust Gas Fumes


  • Avoid inhaling exhaust gases as they contain carbon monoxide, which is a potentially toxic gas that is colourless and odourless.
  • If you are in a parked motor home with either the engine running or a generator running there is a potential for exhaust fumes to filter back into the motor home.

To avoid breathing exhaust gases, follow these precautions:

  • Do not run the engine in confined areas, such as a closed garage, any longer than needed to move your motor home in or out of the area.
  • Windows should be closed while driving or running the generator (if so equipped) to avoid drawing dangerous exhaust gases into the motor home.
  • If you suspect that exhaust fumes are entering the passenger compartment, have the cause determined and corrected as soon as possible.

If you must drive under these circumstances, close all the windows, and adjust the heating or cooling system to force outside air into the motor home (set the blower on high speed).
The best protection against carbon monoxide entry into the motor home is a properly main-tained ventilation system and an active carbon monoxide detector. To allow for proper operation of the motor home ventilation system, keep the ventilation inlet grill(s) clear of snow, leaves or other obstructions at all times.

It is recommended that the exhaust system and vehicle body be inspected by a qualified mo-tor home service center:

  • Each time the engine is ready for an oil change.
  • Whenever a change in the sound of the exhaust is noticed.
  • Whenever the exhaust system, underbody or rear of the vehicle is damaged.

Propane Gas System

Propane or LP (liquefied petroleum) gas is an efficient form of energy when proper handling and safety precautions are observed. The propane system in your motor home furnishes the fuel for cooking, heating, hot water and can be an alternative energy source for refrigeration. Propane is heavier than air and tends to flow to lower areas and will sometimes pocket in these low areas, such as the floor. Your motor home is equipped with a propane alarm (refer to Safety Precautions, Combination Carbon Monoxide (CO)/Propane Alarm).

The propane fuel system is comprised of numerous components such as the propane container, hoses, propane gas regulator, piping and copper tubing to each appliance.
Your motor home has been carefully tested at the factory and by your selling dealer for leakage. Travel vibrations can loosen fittings. Have the vehicle propane system checked at all connections soon after the purchase of your vehicle, and after the initial filling of the propane tanks.
Continued periodic checks of the propane system at 5,000 miles of travel (or at least once a year) by a qualified propane service representative as part of your normal maintenance is recommended. Hand-tighten the LP gas system valves only, do not use a wrench or pliers as over-tightening may damage the valve seals and cause them to leak.

NOTE: All propane lines have been checked with air pressure at the time of manufacture. Dealers are required to recheck and adjust pressure before retail delivery.

Propane Gas Container
Propane is a true gas compressed into a liquid form. As the fuel is released from the container, it changes to vapor which is then used for the operation of the appliances. Propane will not run through the appliances in the liquid state.
A permanently mounted A.S.M.E.-approved propane container is located under the floor of the motor home.

Servicing or Filling
Because the container is not removable, the motor home will need to be driven to a qualified propane facility for servicing or filling.
Only the authorized gas service technician(s) should be near the motor home while the pro-pane tank is being filled. The new propane container must be carefully purged for proper appliance performance and operation. The propane tank must NEVER BE OVERFILLED.
Replace all protective covers and caps on the propane system and/or container after filling. Make sure the valve is closed and the compartment door is securely latched.

LP Gas Container Overfill
Never allow your propane tank to be filled above the maximum safe level as indicated by the fixed liquid level gauge.
Do not allow the visible gauge to be used for filling. Overfilling the propane container above the liquid capacity indicated on the container could allow liquid propane to enter the system that is designed for vapor only creating a hazardous condition.
The following warming label has been placed by the propane container.

Single stage regulator
Some models are equipped with a single-stage regulator.
Two-stage regulator
The two-stage regulator has the only moving component in the propane system. Its sole function is to reduce the pressure from the propane containers to a safe and consistent low operating pressure. The first stage reduces the container pressure to 10-13 lbs. The second stage reduces the 10-13 lbs. of pressure further to an operating pressure of 11” W.C. (water column) or 6.35 oz. of outlet pressure to your appliances.
The second stage is adjustable and will need to be adjusted by your dealer or qualified pro-pane service technician for optimum performance (this adjustment should always be made with a properly calibrated manometer).

If the pressure is too high, it affects performance and safety; if the pressure is too low, your appliances will not operate correctly.
If your recreation vehicle is equipped with the “automatic” two-stage regulator, with both cylinders full of propane, turn the lever on the regulator towards the cylinder you wish to use first. This will be the “supply” cylinder and the other the “reserve”. Slowly open both cylinder valves. The indicator on top of the regulator will turn bright green. When the cylinder becomes empty, the indicator will change to bright orange. Turn the regulator lever to the side of the “reserve” cylinder and the green signal should return. You may now remove the empty cylinder to have it refilled without interrupting the flow from the full bottle. After filling the cylinder, connect the pigtail hose and slowly open the bottle valve.
Refer to the manufacturer’s pamphlet included in your warranty packet and follow all safety instructions and warnings listed.
