Engine Oil Pressure Light and Gage If you make a hard stop, the light may come on for a moment. But, when this light cumes on and stays on, it means oil isn't going through your engine properly. You could be low on oil, oryou might have some other oil problem. See your dealer for service. OIL CAUTION: Don't keep driving if the oil pressure is low. If you do, your engine canbecome so hot that it catches fire. You or others could be burned. Check your oil as soon as possible and have your vehicle serviced. These lights tell you if there could be a problem with your engine oil pressure. If your car has the optional gage cluster, you can read your oil pressure directly from the gage on your instrument panel. There arethree ways this light can come on briefly, which is normal and doesn't show a problem. They are: The light comes on when you turn your key to RUN. It goes off once you turn it to START. That's just a check to be sure the light works. If it doesn't, be sure to have it fixed so it will be there to warn you if something goes wrong. If you're "idling" at a stop sign,the light may blink on and then off. I NOTICE: Damage to your engine from neglected oil problems can be costly and is not covered by your warranty. I 1 2-64
