Low Oil Level Light Your engine is equipped with an oil level monitoring system. When the ignition key is turned on, the LOW OIL light will briefly flash. Change Oil Soon Light The CHG OIL SOON light should come on as a bulb check when you start the engine. If the light doesn't come on, have it serviced. If the light does not flash, have it fixed so it will be ready to warn you if there's a problem. If the light stays on, stop the vehicle on a level surface and turn the engine off. Check the oil level using the engine oil dipstick. (See "Engine Oil" in the Index.) If the light does not flash, have the low oil level sensor system repaired so it will be ready to warn you if there's a problem. The oil level monitoring system only checks the oil level during the brief period between key on and engine crank. It does not monitor the engine oil level when the engine is running. Additionally, an oil level check is only performed if the engine has been turned off for a considerable period of time, allowing the oil normally in circulation to drain back into the oil pan. If the CHG OIL SOON light comes on and stays on after you start the engine, have the oil changed. For additional information, see "Engine Oil, When to Change" in the Index. To reset the CHG OIL SOON light, see "Oil Life System" in the Index. 2-57
