Engine Coolant Temperature Warning Light
The engine coolant temperature warning light comes on briefly when the vehicle is started.
If it does not, have the vehicle serviced by your dealer. 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 and turn off the vehicle to avoid damage to the engine.
A warning chime sounds when this light is on.
See Engine Overheating for more information.
