Low Oil Level Light Your engine isequipped with an oil level monitoring system. When the ignition key is turned on, the LOW OIL LEVEL light will briefly flash. If the light does not flash, have it fixed so it will be ready to warn you if there's a problem. Engine Coolant TemperatureLight This lighttells you that your engine coolant has overheated or yourradiator cooling fan is not working. TEMP If the light stays on, stop th'evehicle 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 you have been operating your vehicle under normal driving conditions, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. The oil level monitoring system only checks oil level during the brief period between key 'onand engine crank. It does not monitor engine oil level when the engine is running. Additionally, an oillevel 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. In "Problems on the Road," this manual shows what to do. See "Engine Overheating" in the Index. 2-74
