StabiliTrak Indicator Light
If the warning light does not come on then, have it
fixed so it will be ready to warn you if there is a
problem. If it stays on, or comes on when you are
driving, there may be a problem with your
®
StabiliTrak system and your vehicle may need
service. When this warning light is on, the system
is off and will not limit wheel spin. Adjust your
driving accordingly.
This light will also flash when the StabiliTrak
system is active.
®
If the StabiliTrak system warning light comes on
and stays on for an extended period of time
when the system is turned on, your vehicle needs
service. See StabiliTrak
for more information.

If equipped, this warning

Engine Coolant Temperature Gage

United States
This gage shows the engine coolant temperature.
It also provides an indicator of how hard your
vehicle is working. During a majority of the
operation, the gage will read 210°F (100°C) or
less. If you are pulling a load or going up hills, it is
normal for the temperature to fluctuate and
approach the 250°F (122°C) mark. If the gage
reaches the 260°F (125°C) mark, it indicates that
the cooling system is working beyond its
capacity.
See Engine Overheating on page 452.
