Engine Coolant Temperature Gage This gage measures the temperature of the vehicle's engine. If the indicator needle moves into the shaded area, the engine is too hot. A temperature indicator light will turn on and a chime will sound. Low Coolant Warning Light This light comes on briefly when you turn your ignition on. If you have been operating your vehicle under normal driving conditions, and the temperature indicator light comes on, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. If this light comes on and stays on, the coolant level in your vehicle is low. If the light is on along with an overheat warning, you may have a serious overheating problem. See Engine Coolant Temperature Gage on page 3-33. Notice: Driving with the low coolant warning light on could cause your vehicle to overheat. See "Engine Overheating" under Engine Coolant on page 5-23. Your vehicle could be damaged and the damages might not be covered by your warranty. See Engine Coolant on page 5-23 for information on what to do. Your vehicle should be serviced as soon as possible. 3-33
