Engine Coolant Temperature Gage
United States Canada
Your vehicle has a gage that shows the engine coolant
temperature. If the gage pointer moves into the shaded
area, the engine is too hot.
That reading means the same thing as the warning light.
It means that the engine coolant has overheated. If you
have been operating the vehicle under normal
conditions, you should pull off the road, stop the
vehicle, and turn off the engine as soon as possible.
See “Engine Overheating” in the Index.
Low Coolant Warning Light
If this light comes on,
the system is low on
coolant and the engine
may overheat.
See “Engine Coolant” in the Index and have the vehicle
serviced as soon as possible.
