Engine coolant temperature gauge NOTICE zDo not remove the thermostat in the engine cooling system as this may cause the engine to overheat. The thermostat is designed to control the flow of coolant to keep the temperature of the engine within the specified operating range. zDo not continue driving with an overheated engine. See "If your vehicle overheats" in Part 4. The gauge indicates the engine coolant temperature when the ignition switch is on. The engine operating temperature will vary with changes in weather and engine load. If the needle points to the red zone or higher, stop your vehicle and allow the engine to cool. Your vehicle may overheat during severe operating conditions, such as: S Driving up a long hill on a hot day. S Reducing speed or stopping after high speed driving. S Idling for a long period with the air conditioning on in stop-and-go traffic. S Towing a trailer. Oil pressure gauge The oil pressure gauge indicates engine oil pressure when the ignition switch is on. Check it while driving to make sure that the needle is in the proper range. If the oil pressure should stay below the normal range, pull off the road to a safe place and stop the engine immediately. Call a Toyota dealer or qualified repair shop for assistance. Oil pressure may not build up when the oil level is too low. The oil pressure gauge is not designed to indicate oil level, and the oil level must be checked using the level dipstick. 50
