Operation CHARM: Car repair manuals for everyone.

While Operating The Vehicle

Automatic Transmission Shift Indicator Operation (if equipped)
Make sure the indicator points to the gear chosen.

Windshield Wiper And Washer Operation
Note the operation and condition of the wiper blades and the flow and aim of the washer spray.

Defroster Operation
Periodically check the air flow from the ducts at the inside base of the windshield. Do this with the heater controls set in the defrost position and the fan on high.

Horn Assembly Operation
Blow the born assembly occasionally to make sure it works. Check all button locations.

Brake System Operation
Be alert to abnormal sounds, increased brake pedal travel or repeated pulling to one side when braking. Also, if the brake warning lamp or antilock brake system warning lamp goes on or flashes, something may be wrong with part of the brake system.

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

Tires, Wheel Assemblies And Alignment Operation
Be alert to a vibration of the steering wheel or seat at normal highway speeds. This may mean a wheel assembly balance is needed. Also, a pull right or left on a straight and level road may show the need for a tire pressure adjustment or a wheel alignment.

Steering System Operation
Be alert to changes in steering action. An inspection is needed when the steering wheel is harder to turn, or has too much free play, or if unusual sounds are noted when turning or parking.

Headlamp Aim
Take note of the light pattern occasionally. If beams seem to be improperly aimed, headlamps should be checked and adjusted as necessary.
