Vehicle Warning Lights

Engine Warning Lights

Oil Pressure Light

The oil pressure light is usually an oilcan symbol , although on older vehicles it may be a light with the word “OIL.” It comes on when there is a drop in engine oil pressure. Of all the warning lights, the oil pressure light indicates the greatest potential for serious mechanical damage.

If the oil pressure warning light comes on and stays on, pull off the road at the first safe opportunity, shut off the engine and call for assistance.

Engine Temperature Light

The engine temperature light is usually a thermometer symbol, although in older vehicles it may be a light displaying the word “TEMP.” It comes on when the engine temperature is above the recommended maximum. Unless the temperature is quickly brought under control, major engine damage is likely to occur.

If there are any signs of a cooling system leak, pull off the road at the earliest safe opportunity, shut off the engine and call for assistance.

Be careful when opening the hood in the presence of steam, and never remove the radiator cap when the engine is hot.

Charging System Light

The charging system light is usually a battery symbol, although on older vehicles it may be a light displaying the word “ALT” or “GEN.” It comes on when the vehicle electrical system is no longer being supplied power by the alternator.

If this light comes on, shut down all unnecessary electrical loads such as the radio, heater or air-conditioning, and then drive the vehicle to a repair facility immediately for further inspection.
