Warning Light
This light will also come on briefly when the
vehicle is started.
If the light does not go out or comes on and stays
on while driving, there may be a problem with
the cooling system. Driving with engine coolant
temperature light on could cause your vehicle
to overheat, see Overheated Engine Protection
Operating Mode on page 395. See Engine
Overheating on page 393 and DIC Warnings and
Messages on page 264 for more information.
The engine coolant
temperature warning
light will come on when
the engine is very hot.

Engine Coolant Temperature Gage

It can be used to see when your engine has
warmed up and to make sure your cooling system
is operating properly. If the gage pointer moves
into the shaded area, the engine coolant is too hot
and the engine coolant temperature warning
light will come on. See Engine Overheating on
page 393 for more information.
This gage shows the
engine coolant
temperature.
