For 1990-2009 cars only

Listed below are inspections and services which should be performed by either the owner or a qualified technician to help ensure proper dependability, emission control performance, an safety of your vehicle. These inspections and services are grouped into categories that indicate when the service should be performed.

Promptly take any problems to your retailer or another qualified technician for correction. Any safety-related or emission-related parts that could have been damaged in an accident should be inspected, and all needed repairs to the damaged parts should be done before operating your vehicle.

While Operating Your Vehicle

Automatic Transmission Shift Indicator Operation:

Make sure the indicator points to the gear you are in.

Horn Operation:

Operate the horn occasionally to make sure it works.

Brake System Operation:

Be alert to abnormal sounds, increased brake pedal travel, or repeated pull to one side when braking. Also, if the brake warning light goes on, something may be wrong with part of the brake system; have it inspected and repaired at once.

Restraint System Operation:

Now and ten, make sure all belts, buckles, latch plates, retractors, anchorages, and reminder systems are working properly. Look for any loose parts or damage. If you see anything that might keep a restraint system from doing its job, have it serviced as necessary.

Exhaust System Operation:

Be alert to any changes in the sound of the exhaust system or any smell of fumes. These are signs the system may be leaking or overheating. Have it inspected and repaired at once.

Tire and Wheel Operation:

Be alert to a vibration of the steering wheel or the seat at normal highway speeds, or a pull to the right or left on a straight, level road. This may indicate the need for a tire pressure check. If the tire pressure is correct, and you will notice any of these conditions, see your retailer.

Steering System Operation:

Be alert to changes in steering actions. An inspection is needed when the steering wheel is harder to turn or has more free play than normal. If abnormal sounds are noted when turning or parking, the steering system should be inspected. Be alert to any rattles or squeaks that may occur at different engine speeds or over different road conditions.

Headlight Aim Adjustment:

Take note of the light pattern occasionally. If beam aim appears different than normal, headlight adjustment should be checked.
