Engine Overheating
The vehicle has an indicator to warn of engine overheating.
There is an engine coolant temperature warning light on the vehicle's instrument panel.
See Engine Coolant Temperature Gauge.
If the decision is made not to lift the hood when this warning appears, but instead get service help right away. See Roadside Service (U.S. and Canada) or Roadside Service (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, 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 because of being driven with no coolant, the vehicle can be badly damaged. The costly repairs would not be covered by the vehicle warranty.
