Engine Coolant Temperature Gage

This gage shows the engine coolant temperature. If the pointer moves towards the H (United States) or shaded in thermostat symbol area (Canada), the engine is too hot.
A temperature indicator light will turn on and a chime will sound.
If the vehicle has been operating under normal driving conditions, and the temperature indicator light comes on, pull off the road, stop the vehicle and turn off the engine as soon as possible.
