Your vehicle is equipped with one of these gages. With the ignition in RUN, this gage shows the engine coolant temperature.

If the gage pointer moves into the red area, your engine is too hot! It means that your engine coolant has overheated. The CHECK GAGES light should come on if this condition exists. See Check Gages Warning Light for more information. If you have been operating your vehicle under normal conditions, you should pull off the road, stop your vehicle and turn off the engine as soon as possible. See Engine Overheating for more information.
