Oil Pressure Light If you have a problem with your oil pressure, this light may stay on after you start the engine, or it may come on while you are driving. {CAUTION: Don't keep driving if the oil pressure is low. If you do, your engine can become so hot that it catches fire. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. This indicates that oil is not going through your engine quickly enough to keep it lubricated. The engine could be low on oil or could have some other oil problem. Have it fixed right away. The oil light could also come on in two other situations: Notice: Damage to your engine from neglected oil problems can be costly and is not covered by your warranty. • When the ignition is on but the engine is not running, the light will come on as a test to show you it's working. The light will go out when you turn the ignition to RUN. If it doesn't come on with the ignition on, you may have a problem with the fuse or bulb. See Fuses and Circuit Breakers on page 5-99. • If you make a hard stop, the light may come on for a moment. This is normal. 3-43
