However, some common warning lights you might see include:
* Check Engine Light (CEL): This is probably the most common. It indicates a problem detected by the car's onboard diagnostic system (OBD). This requires a diagnostic scan to determine the specific code and cause.
* Oil Pressure Light: Illuminates if the oil pressure is too low. This is a serious problem and requires immediate attention to prevent engine damage. Don't drive the car if this light is on.
* Battery Light: Indicates a problem with the charging system. This could be a bad alternator, battery, or related wiring.
* Brake Warning Light: Usually illuminates if the parking brake is engaged, but can also indicate low brake fluid or a problem with the brake system.
* Temperature Light (Overheating): Indicates the engine is overheating. Pull over immediately and let the engine cool down before attempting to diagnose the problem.
* Alternator Light: Indicates a problem with the alternator.
* Seat Belt Light: A reminder to fasten your seat belt.
* Airbag Light: Indicates a potential problem with the airbag system. This should be checked by a mechanic.
To find out what your specific warning lights mean:
1. Locate your owner's manual: This is the most reliable source of information. It will have a section showing illustrations of the warning lights and explaining their meanings.
2. Check online resources: Websites like Haynes and Chilton often have repair manuals and information for older vehicles. Search for "1992 Pontiac Grand Prix warning lights" to find relevant resources.
3. Have it scanned: A mechanic can plug a diagnostic scanner into your car's OBD port to read any trouble codes stored by the computer. This can greatly help in identifying the cause of any illuminated warning lights.
Don't ignore any warning lights. They are there to alert you to potential problems that could lead to costly repairs or even accidents.
