The engine coolant temperature warning light comes on briefly when the engine is started.

If it does not, have the vehicle serviced by your dealer/retailer. If the system is working normally the indicator light then goes off.

If the light comes on and stays on while driving, the vehicle may have a problem with the cooling system. Stop the vehicle and turn off the engine as soon as possible to avoid damage to the engine. A warning chime sounds when this light is on.

See Engine Overheating for more information.
