The interior temperature sensor
located on the instrument panel to
the right of the steering column,
measures the temperature of the
air inside the vehicle.
There is also an exterior
temperature sensor located behind
the front grille. This sensor reads the
outside air temperature and helps
maintain the temperature inside the
vehicle. Any cover on the front of the
vehicle could cause a false reading
in the displayed temperature.The climate control system uses
the information from these sensors
to maintain comfort settings by
adjusting the temperature, fan
speed, and the air delivery mode.
The system may also supply cooler
air to the side of the vehicle facing
the sun. The recirculation mode will
also be used as needed to maintain
cool outlet temperatures.
Outlet Adjustment
Use the slider switch in the center
of the outlet, to change the direction
of the air ow. Use the thumbwheel
near the outlet to control the amount
of air ow or to shut off the air ow.
Keep all outlets open whenever
possible for best system
performance.
Operation Tips
Clear away any ice, snow, or
leaves from the air inlets at
the base of the windshield that
can block the ow of air into
the vehicle.
Use of non-GM approved hood
de ectors can adversely affect
the performance of the system.
Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle
more effectively.
If fogging reoccurs while in
vent or bi-level modes with mild
temperature throughout the
vehicle, turn on the air conditioner
to reduce windshield fogging.

Compass Calibration
The compass can be manually
calibrated. Only calibrate the
compass in a magnetically clean
and safe location, such as an
open parking lot, where driving
the vehicle in circles is not a danger.
It is suggested to calibrate away
from tall buildings, utility wires,
manhole covers, or other industrial
structures, if possible.
If CAL should ever appear in the
DIC display, the compass should
be calibrated.
If the DIC display does not show a
heading, for example, N for North,
or the heading does not change after
making turns, there may be a strong
magnetic eld interfering with the
compass.Such interference may be caused by
a magnetic CB or cell phone antenna
mount, a magnetic emergency light,
magnetic note pad holder, or any
other magnetic item. Turn off the
vehicle, move the magnetic item,
then turn on the vehicle and calibrate
the compass.
To calibrate the compass, use the
following procedure:
Compass Calibration Procedure
1. Before calibrating the compass,
make sure the compass zone
is set to the variance zone in
which the vehicle is located.
See “Compass Variance (Zone)
Procedure” earlier in this section.
Do not operate any switches
such as window, sunroof, climate
controls, seats, etc. during the
calibration procedure.2. Press the vehicle information
button until PRESS
VTO
CALIBRATE COMPASS
displays.
3. Press the set/reset button to start
the compass calibration.
4. The DIC will display
CALIBRATING: DRIVE IN
CIRCLES. Drive the vehicle
in tight circles at less than
5 mph (8 km/h) to complete the
calibration. The DIC will display
CALIBRATION COMPLETE for a
few seconds when the calibration
is complete. The DIC display will
then return to the previous menu.

If the system fails to turn on or
activate, the StabiliTrak light along
with one of the following messages
will be displayed on the Driver
Information Center (DIC):
TRACTION CONTROL OFF,
SERVICE TRACTION CONTROL,
SERVICE STABILITRAK. If these
conditions are observed, turn the
vehicle off, wait 15 seconds, and
then turn it back on again to reset the
system. If any of these messages still
appear on the Driver Information
Center (DIC), the vehicle should be
taken in for service. For more
information on the DIC messages,
seeDriver Information Center (DIC)
on page 3-44.
The StabiliTrak light will ash on the
instrument panel cluster when the
system is both on and activated.The system may be heard or felt
while it is working; this is normal.
The traction control disable button is
located on the instrument panel
below the climate controls.
The traction control part of
StabiliTrak can be turned off by
pressing and releasing the traction
control disable button.
Traction control can be turned on by
pressing and releasing the traction
control disable button if not
automatically shut off for any other
reason.
When the traction control system is
turned off, the StabiliTrak light
and the appropriate traction control
off message will be displayed on
the DIC to warn the driver. The
vehicle will still have brake-tractioncontrol when traction control is off,
but will not be able to use the engine
speed management system. See
“Traction Control Operation” next for
more information.
When the traction control system
has been turned off, system noises
may be heard and felt as a result
of the brake-traction control working.
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 want to “rock” the
vehicle to 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 4-17.

Blizzard Conditions
Being stuck in snow can be in a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program on page 7-6.
To get help and keep everyone
in the vehicle safe:
Turn on theHazard Warning
Flashers on page 3-5.
Tie a red cloth to an outside
mirror.
{CAUTION
Snow can trap engine exhaust
under the vehicle. This may cause
exhaust gases to get inside.
Engine exhaust contains carbon
monoxide (CO) which cannot be
seen or smelled. It can cause
unconsciousness and even death.
(Continued)
CAUTION (Continued)
If the vehicle is stuck in the snow:
Clear away snow from
around the base of your
vehicle, especially any that is
blocking the exhaust pipe.
Check again from time to
time to be sure snow does
not collect there.
Open a window about two
inches (5 cm) on the side of
the vehicle that is away from
the wind to bring in fresh air.
Fully open the air outlets on
or under the instrument
panel.
(Continued)
CAUTION (Continued)
Adjust the Climate Control
system to a setting that
circulates the air inside the
vehicle and set the fan speed
to the highest setting. See
Climate Control System in
the Index.
For more information about
carbon monoxide, seeEngine
Exhaust on page 2-30.
Snow can trap exhaust gases
under your vehicle. This can
cause deadly CO (carbon
monoxide) gas to get inside.
CO could overcome you and kill
you. You cannot see it or smell it,
so you might not know it is in your
vehicle. Clear away snow from
around the base of your vehicle,
especially any that is blocking the
exhaust.
