If you're "idling" at a stop sign, the light may blink on and then off. "Check Oil Level" Light (Option) The "Check Oil Level" light is lit for three seconds as a bulb check each time the ignition key is turned to the RUN position. If the light doesn't come on, have your vehicle serviced. If you make a hard stop, the light may come on for a moment. When this light comes on and stays on, it means oil isn't going through your engine properly, You could be low on oil, or you might have some other oil problem. CHECK OIL LEVEL If the engine oil is more than one quart low, the light will come on briefly, then go off for 15-25 seconds, and then come back on for 20-40 seconds. However, the system will not register low engine oil if it has not been more than eight minutes since the engine was last shut off. NOTICE: Damage to your engine from neglected oil problems can be costly and is not covered by your warranty. If the "Check Oil Level" light comes back on, the engine oil should be checked at the.dipstick then brought up to the proper level if necessary. See "Engine Oil" in the Index.
