The following information covers the checks and services required to retain the safety, dependability, and emission control performance of the vehicle.

Make sure any necessary repairs are completed on time. Whenever any fluids or lubricants are added to the vehicle, make sure that they are the proper ones. Refer to Fluid and Lubricant Recommendations .

It is important to perform these underhood check at each fuel fill.

Engine Oil Level

Check the engine oil level and add the proper oil if necessary.In order to select the proper fluids and lubricants, refer to Fluid and Lubricant Recommendations .

Engine Coolant Level

Check the engine coolant levels and add the proper coolant mixture, if necessary. Refer to Fluid and Lubricant Recommendations .

Windshield Washer Fluid Level

Check the windshield washer fluid level in the windshield washer reservoir and add the proper fluid, if necessary. Refer to Fluid and Lubricant Recommendations .

Tire Inflation

Check tire inflation. Make sure the tires are inflated to the pressures specified on the Certification/Tire label located on the driver's door lock pillar. Refer to Tire Inflation Pressure Specifications .

Cassette Deck

Clean the playback heads and capstan on the cassette deck. Cleaning should be done every 50 hours of tape play. Refer to Cassette Player Care and Cleaning in Entertainment.

Restraint System Check

For seat belt diagnosis information, refer to Operational and Functional Checks in Seat Belts.

Also look for any opened or broken Supplemental Inflatable Restraint (SIR) covers. (The SIR system does not need regular maintenance.)

For SIR Diagnosis refer to SIR General Diagnosis in SIR.

Wiper Blade Check

Inspect wiper blades for wear or cracking. Replace any wiper blade inserts that appear worn, cracked, damaged or that streak or miss areas of the windshield. Refer to Windshield Wiper Blade Replacement in Windshield Wiper/Washer System.

Automatic Transaxle Check

Check the transaxle fluid level; add if needed. Refer to Fluid and Lubricant Recommendations .

A fluid loss may indicate a problem. Check the system and repair if needed.

For the 4T65-E transaxle fluid level inspection Transmission Fluid Check in Transmission/Transaxle-4T65-E. If fluid was added, refer to Transmission Component Fluid Leak Diagnosis in Automatic Transmission/Transaxle-4T65-E.

Weatherstrip Lubrication

Lubricate all door, rear compartment and glass weatherstrips. Refer to Fluid and Lubricant Recommendations for the proper type of lubricant. Colder more damp climates will require more frequent applications.

Key Lock Cylinder Service

Lubricate the lock cylinders with the recommended lubricant. Refer to Fluid and Lubricant Recommendations .

Body Lubrication

Lubricate all of the following areas:

More frequent lubrication may be required when exposed to a corrosive environment. In order to locate the proper lubricant, refer to Fluid and Lubricant Recommendations .

Park/Neutral Position Switch Check

Caution: When performing this check, the vehicle could move suddenly. Personal injury or property damage may result. Make sure there is enough room around the vehicle, in case the vehicle does move. Do not use the accelerator pedal, and be ready to turn OFF the engine immediately if it starts.

1. Make sure there is enough room around the vehicle to allow for any possible vehicle movement.
2. Firmly apply both the parking brake and the regular brake.
3. Try to start the engine in each position. The starter should work only in PARK (P) or NEUTRAL (N).

If the starter operates with the transaxle in any other position, refer to Starting System Circuit Description .

Brake Transmission Shift Interlock (BTSI) Check

Caution: When performing this check, the vehicle could move suddenly. Personal injury or property damage may result. Make sure there is enough room around the vehicle, in case the vehicle does move. Be ready to apply the regular brake immediately should the vehicle begin to move.

1. Park the vehicle on a level surface with enough room around the vehicle to allow for any possible movement.
2. Firmly apply the parking brake. Be ready to apply the regular brake immediately if the vehicle begins to move.
3. With the engine OFF, turn the ignition lock cylinder to the RUN position, but do not start the engine. Without applying the regular brakes, try to move the transmission shift lever out of the PARK position with normal effort.

If the shift lever moved out of PARK, refer to Automatic Transmission Shift Lock Control System Check

Steering Column Park Lock Check

1. With the vehicle parked, set the parking brake.
2. Insert the ignition key into the ignition lock cylinder and turn the ignition lock cylinder to OFF.
3. Move the transmission shifter to REVERSE.
4. Try to turn the ignition lock cylinder to LOCK.
5. Repeat Steps 3 and 4 with the transmission shifter in every possible position. If the ignition lock cylinder turns to LOCK when the transmission shifter is in ANY position other than PARK, repair the park lock system. Refer to Automatic Transmission Shift Lock Control System Check
6. Turn the ignition lock cylinder to OFF.
7. Try to remove the key from the ignition lock cylinder.
8. Repeat Steps 6 and 7 with the ignition lock cylinder in every possible position. If the key comes out of the ignition lock cylinder in ANY position other than LOCK, repair the system. Refer to Automatic Transmission Shift Lock Control System Check

Parking Brake and Automatic Transmission PARK Mechanism Check

Caution: When performing this check, the vehicle could begin to move. Personal injury or property damage may result. Make sure there is enough room in front of the vehicle, in case the vehicle begins to roll. Be ready to apply the regular brake immediately should the vehicle begin to move.

To check the parking brake, perform the following steps:

1. Park on a fairly steep hill, with the vehicle facing downhill.
2. Apply the regular brake and set the parking brake.
3. Start the engine.
4. Shift the transmission to NEUTRAL.
5. Slowly remove your foot from the regular brake pedal. Do this until the vehicle is held ONLY by the parking brake.

If the parking brake fails to hold the vehicle, repair the system. For shoe adjustment refer to Parking Brake Shoe Adjustment and for cable adjustment refer to Park Brake Cable Service/Adjustment in Parking Brake.

To check the transmission park mechanism, perform the following steps:

1. Start the engine.
2. Shift the transmission to PARK.
3. Release all of the vehicle brakes.

If the park mechanism fails to hold the vehicle, repair the system.

For the 4T65-E transmission, refer to No Park Range in Transmission/Transaxle-4T65-E.

Underbody Flushing Service

Use plain water to flush any corrosive materials from the underbody. Take care to clean thoroughly any areas where mud and other debris can collect.
