Ashtray(s) and Cigarette Lighter
If your vehicle has this feature it is located in the center
console or on the instrument panel. Pull up on the
ashtray door to open it if it is in the console or pull the
door open it if it is on the instrument panel.
Notice:If papers, pins, or other ammable items
are put in the ashtray, hot cigarettes or other
smoking materials could ignite them and possibly
damage the vehicle. Never put ammable items
in the ashtray.
To remove the ashtray, pull it out from the console or
from the slide out door. To reinstall the ashtray,
slide it back to the original position.
To use the cigarette lighter, if the vehicle has one, push
it in all the way, and let go. When it is ready for use,
it will pop back out by itself.
Do not use the lighter to plug in accessory devices. Use
the power outlets provided.
Notice:Holding a cigarette lighter in while it is
heating does not let the lighter back away from the
heating element when it is hot. Damage from
overheating can occur to the lighter or heating
element, or a fuse could be blown. Do not hold a
cigarette lighter in while it is heating.

Driver’s Side Temperature Control
The driver side temperature buttons are used to adjust
the temperature of the air coming through the system
on the drivers side. The temperature can be adjusted
even if the system is turned off. This is possible
since outside air will always ow through the system as
the vehicle is moving forward unless it is set to
recirculation mode. See “Recirculation” later in this
section.

Sensors
The solar sensor, located in the defrost grille, middle of
the instrument panel, monitors the solar heat. Do not
cover the solar sensor or the system will not work
properly.There is also an interior
temperature sensor
located next to the steering
wheel that measures the
temperature of the air
inside your 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 your comfort setting by
adjusting the outlet 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.

4. Press the trip/fuel button until the vehicle heading, for
example, N for North, is displayed in the DIC. Or, if
the vehicle does not have DIC buttons, press and
hold the trip odometer reset stem for two seconds to
select the next available variance zone. Repeat this
step until the appropriate variance zone is displayed.
5. If calibration is necessary, calibrate the compass.
See “Compass Calibration Procedure” following.
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 COMPAS (Compass)
displays. Or, if the vehicle does not have DIC
buttons, press the trip odometer reset stem until
CALIBRATE COMPASS displays.
3. Press the set/reset button to start the compass
calibration. Or, if the vehicle does not have DIC
buttons, press and hold the trip odometer reset stem
for two seconds 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, STABILITRAK OFF, SERVICE
STABILITRAK. If these DIC messages appear, make
sure the StabiliTrak system has not been turned
off using the StabiliTrak on/off button. Then turn the
steering wheel clockwise from the nine o’clock position
to the three o’clock position. If this clears the
message(s), the vehicle does not need servicing. If this
does not clear the message(s), then 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 3-46.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 StabiliTrak button if
both systems (traction control and StabiliTrak) were
previously on. To disable both traction control and
StabiliTrak, press and hold the button for ve seconds.

CAUTION: (Continued)

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.
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, see
Engine Exhaust on page 2-53.
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.Run the engine for short periods only as needed to
keep warm, but be careful.
To save fuel, run the engine for only short periods as
needed to warm the vehicle and then shut the engine off
and close the window most of the way to save heat.
Repeat this until help arrives but only when you
feel really uncomfortable from the cold. Moving about to
keep warm also helps.
If it takes some time for help to arrive, now and then
when you run the engine, push the accelerator
pedal slightly so the engine runs faster than the idle
speed. This keeps the battery charged to restart
the vehicle and to signal for help with the headlamps.
Do this as little as possible to save fuel.

If either the CHECK TRAILER WIRING or SERVICE
TRAILER BRAKE SYSTEM message is displayed while
driving the vehicle, power is no longer available to
the trailer brakes. When traffic conditions allow, carefully
pull the vehicle over to the side of the road and turn
the ignition off. Check the wiring connection to the trailer
and turn the ignition back on. If either of these
messages continues, either the vehicle or trailer needs
service.
An authorized GM dealer may be able to diagnose
and repair problems with the trailer. However, any
diagnosis and repair of the trailer is not covered under
the vehicle warranty. Please contact your trailer
dealer for assistance with trailer repairs and trailer
warranty information.Driving with a Trailer
{CAUTION:
When towing a trailer, exhaust gases may collect
at the rear of the vehicle and enter if the liftgate,
trunk/hatch, or rear-most window is open.
Engine exhaust contains carbon monoxide (CO)
which cannot be seen or smelled. It can cause
unconsciousness and even death.
To maximize safety when towing a trailer:
Have the exhaust system inspected for leaks
and make necessary repairs before starting a
trip.
Never drive with the liftgate, trunk/hatch, or
rear-most window open.
Fully open the air outlets on or under the
instrument panel.
Adjust the Climate Control system to a setting
that brings in only outside air and set the fan
speed to the highest setting. See Climate
Control System in the Index.
For more information about carbon monoxide, see
Engine Exhaust on page 2-53.

Uniform Tire Quality Grading
Quality grades can be found where applicable on
the tire sidewall between tread shoulder and
maximum section width. For example:
Treadwear 200 Traction AA
Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration (NHTSA), which
grades tires by treadwear, traction, and
temperature performance. This applies only to
vehicles sold in the United States. The grades are
molded on the sidewalls of most passenger car
tires. The Uniform Tire Quality Grading (UTQG)
system does not apply to deep tread, winter-type
snow tires, space-saver, or temporary use
spare tires, tires with nominal rim diameters of
10 to 12 inches (25 to 30 cm), or to some
limited-production tires.While the tires available on General Motors
passenger cars and light trucks may vary with
respect to these grades, they must also conform
to federal safety requirements and additional
General Motors Tire Performance Criteria (TPC)
standards.
Treadwear
The treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specied
government test course. For example, a tire
graded 150 would wear one and a half (1.5) times
as well on the government course as a tire
graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from
the norm due to variations in driving habits, service
practices, and differences in road characteristics
and climate.
