For time and/or mileage intervals of scheduled maintenance items, refer to Maintenance Schedule - Short Trip/City or Maintenance Schedule - Long Trip/Highway .

The following text and illustrations describe the details of the required scheduled maintenance services.

For information on the proper fluids and lubricants to use, refer to Fluid and Lubricant Recommendations .

Engine Oil and Filter Change

For the engine oil and filter changing procedure, refer to Engine Oil and Oil Filter Replacement in Engine Mechanical - 1.6 L or Engine Oil and Oil Filter Replacement in Engine Mechanical - 2.0 L.

For information on the correct engine oil quality and viscosity, refer to the following:

Engine Oil Quality

Notice: Use only engine oil with the American Petroleum Institute Certified for Gasoline Engines starburst symbol. Failure to use the recommended oil can result in engine damage not covered by the warranty.


Object Number: 65538  Size: SH

The STARBURST symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry the STARBURST symbol.

Engine Oil Viscosity


Object Number: 65536  Size: MH

Engine oil viscosity (thickness) has an effect on fuel economy and the cold-weather operation (engine starting and oil flow). Lower viscosity engine oils can provide better fuel economy and cold-weather performance. However, higher temperature weather conditions require higher viscosity engine oils for satisfactory lubrication.

SAE 5W-30 is best for your vehicle. However, use 10W-30 if the outside temperature is higher than 18°C (0°F). Do not use other viscosity oils, such as SAE 20W-50.

Notice: Using oils of any viscosity other than those recommended could result in engine damage. When choosing an oil, consider the range of temperatures the vehicle will be operated in before the next oil change. Then, select the recommended oil viscosity.

Important: If your vehicle is operated in an area where the temperature falls below -29°C (-20°F), consider using a SAE 5W-30 synthetic oil or a SAE 0W-30. Both will provide easier cold starting and better protection for the engine at extremely low temperatures.

Chassis Lubrication

Notice: Do not lubricate the parking brake cables. Lubrication destroys the plastic coating on the cable.

Lubrication Points (Rear-Wheel Drive)


Object Number: 179739  Size: MF
(1)Propeller Shaft-Slip Joint
(2)Rear Axle Differential
(3)Clutch Actuator
(4)Master Cylinder
(5)Oil Filter
(6)Steering Gear
(7)Engine
(8)Steering Linkage
(9)Wheel Bearings
(10)Air Cleaner
(11)Transmission

Refer to the illustration for the location of the lubrication points for the chassis. Lubricate transmission shift linkage. Lubricate the park brake guides, underbody contact points and linkage.

Tire and Wheel Inspection and Rotation

Check the tires for abnormal wear for damage. Rotate the tires to equalize the wear and obtain maximum tire life. Refer to Tire Rotation in Tires and Wheels. If irregular or premature wear exists, refer to Tire Diagnosis - Irregular or Premature Wear or Tire Diagnosis - Waddle Complaint in Tires and Wheels.

Drive Belt Inspection

Inspect the drive belt for the following:

    • Cracks
    • Fraying
    • Wear
    • Proper tension
        Belts can have small cracks in individual ribs without affecting performance. Refer to Drive Belt Replacement in Engine Mechanical - 1.6 L or Drive Belt Replacement in Engine Mechanical - 2.0 L for drive belt removal and installation procedures.

Automatic Transaxle Service

Change both the transaxle fluid and the fluid filter. Refer to Automatic Transmission Fluid and Filter Replacement in Automatic Transmission - 4 Speed - M41.

Spark Plug Replacement

For information on the correct type of spark plug, refer to Maintenance Items .

Replace the spark plugs. Refer to Spark Plug Replacement in Engine Electrical.

Spark Plug Wire Inspection

Clean the spark plug wires and inspect for burns, cracks or other damage. Ensure that the fit between the spark plug wire boots at the spark plugs and at the coils is snug. Replace the spark plug wires as needed. Refer to Spark Plug Wire Harness Replacement in Engine Electrical.

Air Cleaner Filter Replacement

For information on the correct type of air cleaner filter, refer to Maintenance Items .

Replace the air cleaner filter. Refer to Air Cleaner Element Replacement in Engine Controls - 1.6 L or Engine Controls - 2.0 L.

Fuel Tanks, Cap and Lines Inspection

Inspect the following components for damage or leaks:

    • The fuel lines
    • The cap
    • The lines
    • The fuel rails
    • The injection assemblies

Inspect the fuel cap gasket for an even filler neck imprint and any damage. Replace parts as needed.

Cooling System Service

Drain, flush and refill the cooling system with new coolant. Refer to Cooling System Draining and Filling and Flushing in Engine Cooling.
