Engine Overheating

The vehicle has several indicators to warn of engine overheating.

There is an engine coolant temperature gauge on the instrument panel cluster.

See Engine Coolant Temperature Gauge on page 5‑14.

The vehicle may also display an ENGINE OVERHEATED IDLE ENGINE and ENGINE OVERHEATED STOP ENGINE message in the Driver Information Center (DIC). See Engine Cooling System Messages on page 5‑39.

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

See Roadside Assistance Program (U.S. and Canada) on page 13‑8 or Roadside Assistance Program (Mexico) on page 13‑10.

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 on page 10‑20 for information on driving to a safe place in an emergency.
