Engine Coolant Temperature
Warning Light
This light will come on
when you first start the
vehicle as a check
to let you know that the
light is working.
It will go out after a few seconds. If the light does not
come on, see your dealer/retailer.
If the light does not go out or if the light comes on and
stays on while you are driving, your vehicle may
have a problem with the cooling system. You should
stop the vehicle and turn off the engine as soon
as possible to avoid damage to the engine. A warning
chime will also sound when this light is on.
See Engine Overheating on page 5-30 for more
information.

engine coolant overheats the engine coolant
temperature warning light will come on. See Engine
