StabiliTrak Off
In this mode, both stability control and part of the
traction control system are disabled. The vehicle will still
have brake-traction control, but will not be able to use
the engine speed management system. System
noises maybe heard as a result of the brake-traction
control coming on. If the controller detects excessive
wheel spin in this mode, the StabiliTrak indicator
light may blink and the STABILITRAK ACTIVE message
may be displayed to warn the driver that damage
may occur to the transfer case.It is recommended to leave the system on for normal
driving conditions, but it may be necessary to turn the
system off if the vehicle is stuck in sand, mud, ice or
snow, and you may want to “rock” the vehicle in an
attempt to free it. It may also be necessary to turn off the
system when driving in extreme off-road conditions where
high wheel spin is required. SeeIf Your Vehicle is Stuck
in Sand, Mud, Ice, or Snow on page 4-20for more
information.
The following chart describes the StabiliTrak system
events and the corresponding messages and lights that
will be displayed on the instrument panel cluster.

Tire Pressure Monitor Operation
This vehicle may have a Tire Pressure Monitor System
(TPMS). The TPMS is designed to warn the driver when
a low tire pressure condition exists. TPMS sensors are
mounted onto each tire and wheel assembly, excluding
the spare tire and wheel assembly. The TPMS sensors
monitor the air pressure in the vehicle’s tires and
transmits the tire pressure readings to a receiver
located in the vehicle.
The TPMS is designed to alert the driver if a low tire
pressure condition exists. Tire pressure levels may also
be checked using the Driver Information Center (DIC)
steering wheel control buttons. See “Tire Pressures”
underDIC Operation and Displays on page 3-42.
When a low tire pressure
condition is detected, the
TPMS will illuminate the
low tire pressure warning
light located on the
instrument panel cluster.
At the same time a message to check the pressure in a
speci c tire appears on the Driver Information Center
(DIC) display. The low tire pressure warning light and the
DIC warning message come on at each ignition cycle
until the tires are in ated to the correct in ation pressure.For additional information and details about the DIC
operation and displays seeDIC Operation and Displays
on page 3-42andDIC Warnings and Messages on
page 3-45.
The low tire pressure warning light may come on in
cool weather when the vehicle is rst started, and then
turn off as you start to drive. This could be an early
indicator that the air pressure in the tire(s) are getting
low and need to be in ated to the proper pressure.
A Tire and Loading Information label, attached to
your vehicle, shows the size of your vehicle’s original
equipment tires and the correct in ation pressure for your
vehicle’s tires when they are cold. SeeInflation - Tire
Pressure on page 5-65. For the location of the Tire and
Loading Information label, seeLoading the Vehicle on
page 4-21. Also seeInflation - Tire Pressure on
page 5-65.
Your vehicle’s TPMS can alert you about a low tire
pressure condition but it does not replace normal tire
maintenance. SeeTire Inspection and Rotation on
page 5-72andTires on page 5-59.
Notice:Using non-approved tire sealants could
damage the Tire Pressure Monitor System (TPMS)
sensors. TPMS sensor damage caused by using
an incorrect tire sealant is not covered by the
vehicle warranty. Always use the GM approved tire
sealant available through your dealer/retailer.
