Oil Pressure Light If your vehicle has the standard instrument panel cluster, this light will come on if there is a problem with your vehicle's engine oil pressure. When this light comes on and stays on, and a chime sounds, it means oil isn't going through the engine properly. The oil could be low, or there might be some other oi' roblem. See your dealer for service. m Don't keep arlvlng if the oil pressure islow. If you do, your engine can becomeso hot that it catches fire. You or others could be burned. Check your oil as soonas possible and have your vehicle serviced. Notice: Damage to your engine from neglected oil problems can be costly ands not covered i by your warranty. OIL If your vehicle has the optional gage cluster, you can read your oil pressure directly from the Driver Information Center (DIC). See DIC Controls and Displays on page 3-47. The oil pressure light will come on briefly when you turn your key to RUN. That's just a check to be sure the light works. This is normal and doesn't show a problem. If it doesn't come on and then go off, be sure to have it fixed so it will be there to warn you if there is a problem. 3-44
