There is a coolant temperature gauge and a engine coolant temperature warning light on the instrument panel cluster that indicate an overheated engine condition. See Engine Coolant Temperature Gauge and Engine Coolant Temperature Warning Light for more information.

If the decision is made not to lift the hood when this warning appears, get service help right away. See Roadside Assistance Program (U.S. and Canada) or Roadside Assistance Program (Mexico).

If the decision is made to lift the hood, make sure the vehicle is parked on a level surface.

Then check to see if the engine cooling fans are running. If the engine is overheating, the fans should be running. If not, do not continue to run the engine and have the vehicle serviced.

Notice:
Engine damage from running the engine without coolant is not covered by the warranty.
