Oil Pressure Light/Gage There are three ways the oil pressure light can come on briefly, which are normal and don'tshow a problem. They are: 0 F Z OIL The light comes on when you turn your keyto RUN. It goes off once you turn the key to START. That's just a check to be sure the light works. If doesn't, it 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. If you make a hard stop, the light may come on for a moment. If your car has the optional gage cluster, the oil pressure gage shows the engine oil pressure in pounds per square inch (psi). Canadian vehicles indicate pressure in kilopascals ( P a ) . When this light comes on and stays on, it means oil isn't going through yourengine properly. You could be low on oil, or you might havesome other oil problem. See your dealer for service. 2-78
