Engine Coolant Temperature Gage
This gage shows the
engine coolant
temperature.
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 5-29 for more information.
Tire Pressure Light
This light comes on briefly
when the engine is started.
This light will also come on when one or more of your
tires are significantly underinflated.
A tire pressure message in the Driver Information Center
(DIC), may accompany the light. See DIC Warnings and
Messages on page 3-80 for more information.
Stop and check your tires as soon as it is safe to
do so. If underinflated, inflate to the proper pressure.
See Tires on page 5-57 for more information.
If a problem is detected with the Tire Pressure Monitor
System, this light will flash for approximately 60 seconds
and then stay on solid for the remainder of the ignition
cycle. See Tire Pressure Monitor System on page 5-68
for more information.
