Engine Coolant Temperature
Warning Light
Engine Coolant Temperature Gage
This light comes on briefly
while starting the vehicle.
If it does not, have the vehicle serviced by the
dealer/retailer. If the system is working normally the
indicator light goes off.
Notice: Driving with the engine coolant temperature
warning light on could cause the vehicle to overheat.
See Engine Overheating on page 6-35. The vehicle’s
engine could be damaged, and it might not be
covered by the vehicle warranty. Never drive with
the engine coolant temperature warning light on.
The engine coolant temperature warning light comes on
when the engine has overheated.
If this happens pull over and turn off the engine as soon
as possible. See Engine Overheating on page 6-35
for more information.
United States
Canada
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.
