StabiliTrak
®

– Stability Control

System

StabiliTrak is an
advanced com-
puter-controlled
vehicle stability
and traction
enhancement
system that
assists with
directional con-
trol of the vehicle
in difficult driving conditions. It turns on
automatically every time your vehicle
is started.
To limit wheelspin and help maintain
directional control, you should always
leave the system on. However, if your
vehicle becomes stuck and rocking the
vehicle is required, the system should
be turned off.
To turn off the traction control part of
the system, press the
(StabiliTrak)
button located on the center of the
instrument panel.
To turn off both the traction control and
stability enhancement systems, press
and hold the button for five seconds.
Both systems are disabled when the
transfer case is in the Four-Wheel-Low
Lock mode. When either system is off,
the StabiliTrak light will illuminate.
See Section 4 of your Owner Manual.

Tire Pressure Monitor

The Tire Pressure Monitor alerts you
when a significant reduction in pressure
occurs in one or more of your vehicle's
tires by illuminating the
Pressure) warning light on the instru-
ment panel cluster. The low tire pressure
warning light will remain on until you
correct the tire pressure. A CHECK TIRE
PRESSURE message may also appear
on the Driver Information Center (DIC).
Correcting the Tire Pressure
When the low tire pressure warning light
illuminates, you must inflate the tire to
the proper tire pressure (just as you
must refuel the vehicle when the low
fuel warning light illuminates). The Tire
and Loading Information label shows the
correct tire pressure for the tires when
they're cold. "Cold" means your vehicle
has been sitting for at least three hours
or driven no more than one mile.
You can temporarily clear the DIC
message by acknowledging it with
your DIC controls. However, at the next
vehicle start-up, the DIC message will
reappear if the tire pressure has not
been corrected.
