Engine Coolant Temperature Warning Light The engine coolant temperature warning light will come on when the engine has overheated. Engine Coolant Temperature Gage The vehicle has a gage that shows the engine coolant temperature. If this happens you should pull over and turn off the engine as soon as possible. See Engine Overheating on page 5-30 for more information. Notice: Driving with the engine coolant temperature warning light on could cause your vehicle to overheat. See Engine Overheating on page 5-30. Your vehicle could be damaged, and it might not be covered by your warranty. Never drive with the engine coolant temperature warning light on. This light will also come on briefly when starting your vehicle. If it does not, have your vehicle serviced. If the gage pointer moves towards the H, the engine is too hot. This reading indicates the same thing as the warning light. It means that the engine coolant has overheated. If the vehicle has been operating under normal driving conditions, pull off the road, stop the vehicle, and turn off the engine as soon as possible. See Engine Overheating on page 5-30. 3-40
