Scheme 1: SERVICE INDICATOR & WARNING LIGHTS

OIL PRESSURE WARNING LIGHT

Light comes on with the ignition switch in the "ON" position as a bulb check and goes out shortly after engine is started. Light indicates low oil pressure, but does not indicate amount of oil in engine. Occasionally, light may come on when engine is hot and idling slowly after a hard drive. This is normal, provided light goes out after engine speed is increased. If it remains on or comes on while driving, stop vehicle, turn off engine and check oil level. If oil level is sufficient, there may be a fault in the lubricating system. Have the system checked and serviced immediately to locate and correct cause. Do not operate vehicle until problem has been corrected.

ALTERNATOR WARNING LIGHT

Light comes on with the ignition switch in the "ON" position as a bulb check and should go out shortly after engine is started to indicate that alternator is operating properly. If light remains on or comes on while driving, it indicates possible fault in the electrical charging system. The alternator belt may be loose or broken. Have the system checked and serviced promptly. Due to the design of the system, a "no charge" condition will also cause the Lambda-sond, parking brake, brake failure, and bulb failure warning lights to also light.

"BRAKE FAILURE" WARNING LIGHT

Light comes on with the ignition switch in the "ON" position as a bulb check and goes out after engine is started. If it remains on or comes on while driving, it indicates low fluid level or fault in one of the brake circuits. If light comes on while driving, check brake fluid level and have the system checked and serviced immediately. Do not continue driving if fluid in reservoir is empty.

PARKING BRAKE WARNING LIGHT

With the parking brake fully or partially engaged, light should come on with the ignition switch in the "ON" position as a bulb check and goes out after engine is started and parking brake fully released. If light does not come on as designed or comes on at any other time, the bulb may be burned out or the parking brake switch may be damaged. Have the system checked and serviced as necessary to correct problem.

BULB FAILURE WARNING LIGHT

Light comes on when the ignition is turned on as a bulb check and goes out after engine is started. If light comes on with engine running, it indicates that one of the bulbs in the low beam headlights, tail lights or brake lights (comes on when brake pedal is depressed) is burned out.
