Engine Coolant Temperature Warning Light This light tells you that the engine coolant has overheated. A warning chime will sound if this light comes on. Engine Coolant Temperature Gage This gage shows the engine coolant temperature. If the gage pointer moves into the shaded area, the engine is too hot. As a check, the light should come on for a few seconds when you start your vehicle. If the light comes on and the chime sounds while you are driving, you should stop your vehicle and turn the engine off as soon as possible. See "Engine Overheating" in the Index for more information. When the pointer is in the shaded area, that means the same thing as when the engine coolant temperature warning light comes on and the chime sounds. See "Engine Coolant Temperature Warning Light" previously in this section and "Engine Overheating" in the Index for more information. 2-72
