The vehicle has a gage that shows the engine coolant temperature.

If the gage pointer moves into the shaded area, the engine is too hot. That reading means the engine coolant has overheated. If you have been operating the vehicle under normal driving conditions, you should pull off the road, stop the vehicle, and turn off the engine as soon as possible.

See Cooling System for more information.
