Rear Window Defogger
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off.
The rear window defogger
turns off automatically after
about 10 minutes. If turned on
again it runs for about five minutes
before turning off. The defogger
can also be turned off by turning
the ignition to ACC/ACCESSORY
or LOCK/OFF.
The rear window defogger can
be set to automatic operation.
See “Climate and Air Quality”
under Vehicle Personalization on
page 5‑39. When auto rear defog is
selected, the rear window defogger
turns on automatically when the
interior temperature is cold and
the outside temperature is about
4°C (40°F) and below. The auto
rear defogger turns off automatically after about 10 minutes, or after
five minutes if the outside
temperature is not as cold.
For vehicles with heated outside
rearview mirrors, they turn on when
the rear window defogger button
is on and help to clear fog or frost
from the surface of the mirror.
See
Heated Mirrors on page 2‑17.
Notice: Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This
may damage the rear window
defogger grid and affect your
radio's ability to pick up stations
clearly. The repairs wouldn't be
covered by your warranty.

Operation Tips
.Keep all outlets open whenever
possible for best system
performance.
.Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
.Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Maintenance
Air Intake
Clear away any ice, snow, or leaves
from the air intake at the base of the
windshield that can block the flow of
air into the vehicle.
Passenger Compartment
Air Filter
The filter removes dust, pollen, and
other airborne irritants from outside
air that is pulled into the vehicle.
The filter should be replaced as part
of routine scheduled maintenance.
See Scheduled Maintenance on
page 11‑2 for replacement intervals.
To find out what type of filter to use,
see Maintenance Replacement
Parts on page 11‑9. The passenger compartment air
filter can be accessed by removing
the entire glove box.
1. Open the passenger side door.
Remove the end cover located
on the side of the instrument
panel in the top right corner.
Remove the screw affixed to
the side of the glove box.
2. Open the glove box door and remove the attached screws
from around the glove box.
3. Lower the loosened glove box housing.
4. Unplug both wire cables and remove the glove box.

9-10 Driving and Operating
Blizzard Conditions
Being stuck in snow can be a
serious situation. Stay with the
vehicle unless there is help nearby.
If possible, use theRoadside
Assistance Program (U.S. and
Canada) on page 13‑8 orRoadside
Assistance Program (Mexico) on
page 13‑10. To get help and keep
everyone in the vehicle safe:
.Turn on the hazard warning
flashers.
.Tie a red cloth to an outside
mirror.
{WARNING
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)
WARNING (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
5 cm (2 in) 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.(Continued)
WARNING (Continued)
For more information about
carbon monoxide, see Engine
Exhaust on page 9‑27.
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.

Driving and Operating 9-31
Uplevel Display Shown,Base Model Similar
The display on the instrument panel
cluster will show which gear the
vehicle is in. The number indicates
the requested gear range when
moving the shift lever forward or
rearward. The transmission will only allow
you to shift into gears appropriate
for the vehicle speed and engine
revolutions per minute (rpm). The
transmission will not automatically
shift to the next lower gear if the
engine rpm is too high, nor to the
next higher gear when the maximum
engine rpm is reached.
While in the DSC mode, the
transmission will automatically
downshift when the vehicle comes
to a stop. This will allow for more
power during take-off.
When accelerating the vehicle from
a stop in snowy and icy conditions,
you may want to shift into second
gear. A higher gear allows you to
gain more traction on slippery
surfaces.
Drive Systems
All-Wheel Drive
Vehicles with this feature always
send engine power to all four
wheels. It is fully automatic, and
adjusts itself as needed for road
conditions.
When using a compact spare
tire on an AWD vehicle, the
system automatically detects
the compact spare and disables
AWD. To restore AWD operation
and prevent excessive wear on
the system, replace the compact
spare with a full-size tire as soon as
possible. See
Compact Spare Tire
on page 10‑85 for more information.

Press and release
gand the traction
control system turns off and the
traction control system warning light
comes on. Press
gagain to turn the
system back on. For information on
turning StabiliTrak off and on, see
Electronic Stability Control (ESC) on

Adding non‐GM accessories can
affect the vehicle's performance.
See Accessories and Modifications
on page 10‑3 for more information.
Electronic Stability
Control (ESC)
The vehicle has a vehicle
stability enhancement system
called StabiliTrak. It is an advanced
computer controlled system that
assists with directional control of the
vehicle in difficult driving conditions.
StabiliTrak activates when the
computer senses a difference
between the intended path and
the direction the vehicle is actually
traveling. StabiliTrak selectively
applies braking pressure at any one
of the vehicle's brakes to help steer
the vehicle in the intended direction.
When the stability control system
activates, the Traction Control
System (TCS)/StabiliTrak light
flashes on the instrument panel.
This also occurs when traction
control is activated. A noise might
be heard or vibration might be felt
in the brake pedal. This is normal.
Continue to steer the vehicle in the
intended direction.
If there is a problem detected with
StabiliTrak, the TCS/StabiliTrak light
comes on and the system is not
operational. See Electronic Stability
Control (ESC)/Traction Control
System (TCS) Indicator/Warning
Light on page 5‑22. Driving should
be adjusted accordingly.
