The engine coolant temperature warning light comes on when the engine has overheated.

If this happens pull over and turn off the engine as soon as possible. See Engine Overheating for more information.

Notice: Driving with the engine coolant temperature warning light on could cause the vehicle to overheat. See Engine Overheating. The vehicle's engine could be damaged, and it might not be covered by the vehicle warranty. Never drive with the engine coolant temperature warning light on.

This light also comes on briefly when starting the vehicle. If it does not, see your delear/retailer.
