Explanation Of Scheduled Maintenance Items

Engine Oil and Filter

The engine oil and filter should be changed at the intervals specified in the maintenance schedule. If the vehicle is being driven in severe conditions, more frequent oil and filter changes are required.

Drive Belts
Inspect all drive belts for evidence of cuts, cracks, excessive wear, or oil saturation and replace them if necessary. Drive belts should be checked periodically for proper tension and adjusted as necessary.

When you are inspecting the belt, turn the engine off. Fuel Lines, Fuel Hoses, and Connections Check the fuel lines, fuel hoses, and connections for leakage and damage. We recommend an authorized HYUNDAI dealer replace any damaged or leaking parts immediately.

Fuel Filter (for gasoline engine)
The fuel filter is considered to be maintenance but periodic inspection is recommended for this maintenance depending on fuel quality. If there are some important matters like fuel flow restriction, surging, loss of power, hard starting problems, etc., replace the fuel filter immediately. Consult an authorized HYUNDAI dealer for details.

Vapor Hose and Fuel Filler Cap
The vapor hose and fuel filler cap should be inspected at the intervals specified in the maintenance schedule. Make sure a new vapor hose or fuel filler cap is correctly replaced.

Vacuum Crankcase Ventilation Hoses (if equipped)
Inspect the surface of the hoses for evidence of heat and/or mechanical damage. Hard and brittle rubber, cracking, tears, cuts, abrasions, and excessive swelling indicate deterioration. Particular attention should be paid to examining those hose surfaces nearest to high heat sources, such as the exhaust manifold. Inspect the hose routing to ensure that the hoses do not come in contact with any heat source, sharp edges or moving component which might cause heat damage or mechanical wear. Inspect all hose connections, such as clamps and couplings, to make sure they are secure, and that no leaks are present. Hoses should be replaced immediately if there is any evidence of deterioration or damage.

Air Cleaner Filter
Have the air cleaner filter replaced by an authorized HYUNDAI dealer.

Spark Plugs
Make sure to install new spark plugs of the correct heat range. When assembling parts, be sure to wipe the inside and outside of the boot bottom of the ignition coil and the insulator of the spark plug with a soft cloth to prevent contamination of the spark plug insulator.

Checking the Engine Oil Level
Engine oil is used for lubricating, cooling, and operating various hydraulic components in the engine. Engine oil consumption while driving is normal, and it is necessary to check and refill the engine oil regularly. Also, check and refill the oil level within the recommended maintenance schedule to prevent deterioration of oil performance. Check the engine oil following the below procedure.

Engine Oil4

  1. Follow all of the oil manufacturer’s precautions.
  2. Be sure the vehicle is on level ground in P (Park) with the parking brake set and the wheels blocked.
  3. Turn the engine on and warm the engine up until the coolant temperature reaches a constant normal temperature.
  4. Turn the engine off, remove the oil filler cap, and pull the dipstick out. Wait for 15 minutes for the oil to return to the oil pan.
  5.  Wipe the dipstick clean and re-insert it fully.
  6. Pull the dipstick out again and check the level. The level should be between F (Full) and L (Low).
  7. If the oil level is below the L, add enough oil to bring the level to F.

Use only the specified engine oil (Refer to the “Recommended Lubricants and Capacities” section in Chapter 2).

To prevent damage to your engine:

  • Do not spill engine oil when adding or changing engine oil. Wipe off spilled oil immediately.
  •  The engine oil consumption may increase while you break in a new vehicle and it will be stabilized after driving 4,000 miles (6,000 km). The engine oil consumption can be affected by driving habits, climate conditions, traffic conditions, oil quality, etc. Therefore, it is recommended that you inspect the engine oil level regularly and refill it if necessary.

Checking the Engine Oil and Filter

Engine Oil3

  • The lubrication, rust prevention, cooling, and cleaning effect of the engine oil will gradually degrade during its use. Have the engine oil and filter changed by an authorized HYUNDAI dealer according to the Oil Life Management System instructions or the Maintenance Schedule at the beginning of this chapter.
  • If the maintenance schedule to replace engine oil is exceeded,
    the engine oil performance may deteriorate, and the engine condition may be affected. Therefore, replace the engine oil according to the maintenance schedule.
  • To keep the engine in optimal condition, use the recommended engine oil and filter. If the recommended engine oil and filter are not used, replace it according to the maintenance schedule under severe usage conditions.
  • The purpose of the maintenance schedule for engine oil replacement is to prevent oil deterioration and it is irrelevant to oil consumption. Check and refill engine oil regularly.

Engine oil contains chemicals known to the State of California to cause cancer, birth defects and reproductive harm. Used engine oil may cause irritation or cancer of the skin if left in contact with the skin for prolonged periods of time. Always protect your skin by washing your hands thoroughly with soap and warm water as soon as possible after handling used oil.

The engine oil is very hot immediately after the vehicle has been driven and can cause burns during replacement. Replace the engine oil after the engine oil has cooled down.

The high-pressure cooling system has a reservoir filled with year-round antifreeze coolant. The reservoir is filled at the factory. Check the antifreeze protection and coolant level at least once a year, at the beginning of the winter season and before traveling to a colder climate.

Checking the Coolant Level

Engine Oil1

Check the condition and connections of all cooling system hoses and heater hoses. Replace any swollen or deteriorated hoses. The coolant level should be filled between the MAX and the MIN marks on the side of the coolant reservoir when the engine is cool. If the coolant level is low, add enough distilled (deionized) water to bring the level to the MAX mark, but do not overfill. If frequent additions are required, see an authorized HYUNDAI dealer for a cooling system inspection.

Never remove the engine coolant cap and/or water-cooled intercooler coolant cap or the drain plug while the engine and radiator are hot. Hot coolant and steam may blow out under pressure, causing serious injury. Turn the vehicle off and wait until the engine cools down. Use extreme care when removing the engine coolant cap and/or water-cooled intercooler coolant cap. Wrap a thick towel around it, and turn it counterclockwise slowly to the first stop. Step back while the pressure is released from the cooling system. When you are sure all the pressure has been released, press down on the cap, using a thick towel, and continue turning counterclockwise to remove it.

The coolant level is influenced by the engine temperature. Before checking or refilling the coolant, turn the engine off.

The electric motor for the cooling fan may continue to operate or start-up when the engine is not running and can cause serious injury. Keep hands, clothing, and tools away from the rotating fan blades of the cooling fan. The electric motor for the cooling fan is controlled by engine coolant temperature, refrigerant pressure, and vehicle speed. As the engine coolant temperature decreases, the electric motor will automatically shut off. This is a normal condition. If your vehicle is equipped with GDI, the electric motor for the cooling fan may begin to operate at any time and continue to operate until you disconnect the negative battery cable

Make sure the coolant cap is properly closed after refilling the coolant. Otherwise, the engine could be overheated while driving.

Engine Oil4

  1. Check if the coolant cap label is straight in front.
  2. Make sure that the tiny protrusions inside the coolant cap are securely interlocked.

Recommended coolant

  • When adding coolant, use only deionized water, distilled water, or soft water for your vehicle and never mix hard water in the coolant filled at the factory.
  • An incorrect coolant mixture can result in severe malfunction or engine damage.
  •  The engine in your vehicle has aluminum engine parts and must be protected by a phosphate-based ethylene glycol coolant to prevent corrosion and freezing.
  •  Do not use alcohol or methanol coolant or mix them with the specified coolant.
  • Do not use a solution that contains more than 60% antifreeze or less than 35% antifreeze, which would reduce the effectiveness of the solution.

For mixing percentage, refer to the following table:

Ambient Temperature Mixture Percentage (volume)
Antifreeze Water
5°F (-15°C) 35 65
-13°F (-25°C) 40 60
-31°F (-35°C) 50 50
-49°F (-45°C) 60 40


If in doubt about the mix ratio, a 50% water and 50% antifreeze mix is the easiest to mix together as it will be the same quantity of each. It is suitable to use for most temperature ranges of -31°F (-35°C) and higher.

Changing Coolant
Have the coolant changed by an authorized HYUNDAI dealer according to the Maintenance Schedule at the beginning of this chapter.

Do not use engine coolant or antifreeze in the washer fluid reservoir. Engine coolant can severely obscure visibility when sprayed on the windshield and may cause loss of vehicle control resulting in an accident. Engine coolant may also cause damage to paint and body trim.

To prevent damage to engine parts, put a thick towel around the engine coolant cap and/or inverter coolant cap before refilling the coolant to prevent the coolant from overflowing into engine parts, such as the alternator.
