Engine Overheating

The vehicle has several indicators to warn of engine overheating.

You will find a warning light about a hot engine as well as an engine coolant temperature gage on the instrument panel cluster.

You may decide not to lift the hood when this warning appears, but instead get service help right away.

See Roadside Assistance Program.

If you do decide 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, both fans should be running. If they are 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.

Notice: If the engine catches fire while driving with no coolant, the vehicle can be badly damaged.
The costly repairs would not be covered by the vehicle warranty. See Overheated Engine Protection Operating Mode for information on driving to a safe place in an emergency.
