This gage shows the engine coolant temperature.

If the indicator on the gage moves towards the shaded area on the thermostat , it means that the engine coolant has overheated. If the vehicle has been operating under normal driving conditions, pull off the road, stop the vehicle and turn off the engine as soon as possible.
