Backglass Antenna
The AM-FM antenna is integrated
with the rear window defogger,
located in the rear window. Make
sure that the inside surface of the
rear window is not scratched and
that the lines on the glass are not
damaged. If the inside surface is
damaged, it could interfere with
radio reception. For proper radio
reception, the antenna connector
needs to be properly attached to the
post on the glass.
If a cellular telephone antenna
needs to be attached to the glass,
make sure that the grid lines for the
AM-FM antenna are not damaged.
There is enough space between
the grid lines to attach a cellular
telephone antenna without
interfering with radio reception.Notice:
Using a razor blade or
sharp object to clear the inside
rear window can damage the rear
window antenna and/or the rear
window defogger. Repairs would
not be covered by the vehicle
warranty. Do not clear the inside
rear window with sharp objects.
Notice: Do not apply aftermarket
glass tinting with metallic film.
The metallic film in some tinting
materials will interfere with or
distort the incoming radio
reception. Any damage caused to
your backglass antenna due to
metallic tinting materials will
not be covered by the vehicle
warranty.
Satellite Radio Antenna
The XM Satellite Radio antenna is
located on the roof of the vehicle.
Keep the antenna clear of
obstructions for clear radio
reception.
If the vehicle has a sunroof, the
performance of the XM system may
be affected if the sunroof is open.

Air Delivery Mode Control:Turn
clockwise or counterclockwise to
change the direction of the airflow
inside the vehicle.
To change the current mode, select
one of the following:
H(Vent): Air is directed to the
instrument panel outlets.
)(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets.
6(Floor): Air is directed to the
floor outlets, with some of the air
directed to the windshield and side
window outlets. In this mode, the
system automatically selects
outside air.
-(Defog): This mode clears the
windshield of fog or moisture. Air is
directed equally to the windshield
and the floor outlets. When defog is
selected, the system turns off
recirculation and runs the air
conditioning compressor unless the
outside temperature is below
4°C (40°F).
0(Defrost): This mode clears
the windshield of fog or frost more
quickly. Air is directed to the
windshield with some air to the side
window vents and the floor vents.
When defrost is selected, the
system automatically forces outside
air into the vehicle. The air
conditioning compressor will run
automatically in this setting, unless
the outside temperature is below
4°C (40°F).
#(Air Conditioning): Press to
turn the air conditioning system on
or off. An indicator light comes
on to show that it is on. The air
conditioning can be selected in any
mode as long as the fan is on and
the outside temperature is above
freezing. A flashing indicator light
indicates that the air conditioning
compressor is currently not
available.
On hot days, open the windows to
let hot inside air escape; then close
them. This helps to reduce the time it takes for the vehicle to cool down.
It also helps the system to operate
more efficiently.
For quick cool down on hot days, do
the following:
1. Select the
Hmode.
2. Press the
#button.
3. Select the coolest temperature for both zones.
4. Select the highest
9speed.
5. When the coolest temperature is selected in the A/C mode, the
system automatically goes into
the recirculation mode to
improve cooling.
Using these settings together for
long periods of time may cause the
air inside the vehicle to become too
dry. To prevent this from happening,
after the air inside the vehicle has
cooled, turn the recirculation
mode off.

8-4 Climate Controls
The air conditioning system
removes moisture from the air,
so a small amount of water may drip
under the vehicle while idling or
after turning off the engine. This is
normal.
:(Outside Air):Press to turn
on outside air. An indicator light
comes on to show that it is on.
Outside air will circulate throughout
the vehicle.
?(Recirculation): Press to
turn on the recirculation mode.
An indicator light comes on to
show that it is on. This mode helps to quickly heat or
cool the air inside the vehicle once
the temperature inside the vehicle is
equal to or better than the outside
temperature. It can be used to
prevent outside air and odors
from entering the vehicle. The
recirculation mode is not available in
outside air, floor, defog, or defrost
modes. If the button is selected
while in these modes, the indicator
flashes three times.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog from the
rear window.
<(Rear Window Defogger):
The
rear window defogger turns off
automatically after it has been
activated for 10 minutes. It can be
turned off manually, by pressing the
button again or by turning the
ignition to the LOCK/OFF position.
The rear window defogger can be
turned on again for additional
window clearing. The length of
defogger operation will increase if
the vehicle is being driven.

For vehicles with heated outside
rearview mirrors, the mirrors heat to
help clear fog or frost from the
surface of the mirror when the rear
window defog button is pressed.
SeePower Mirrors on page 2‑15.
Do not drive the vehicle until all the
windows are clear.
Notice: Do not use anything
sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs would not be covered
by the vehicle warranty. Do not
attach a temporary vehicle
license, tape, a decal or anything
similar to the defogger grid.Air Vents
Use the thumbwheel located below
or to the side of the outlet, to
change the direction of the air flow.
Operation Tips
.Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
may block the flow of air into
the vehicle.
.Use of non-GM approved hood
deflectors may adversely affect
the performance of the system.
.Keep the path under the front
seats clear of objects to help
circulate the air inside the
vehicle more effectively.
.If the airflow seems low when
the fan is at the highest setting,
the passenger compartment air
filter, if equipped, may need to
replaced. For more information,
see Passenger Compartment Air
Filter on page 8‑6 and
Scheduled Maintenance on
page 11‑2.
.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.

9-10 Driving and Operating
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 13‑7.
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 9‑24.
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.

Retained Accessory
Power (RAP)
These vehicle accessories can be
used for up to 10 minutes after the
engine turned off:
.Audio System
.Power Windows
The radio will work when the key is
in ON/RUN or ACC/ACCESSORY.
Once the key is turned from ON/
RUN to LOCK/OFF the radio will
continue to work 10 minutes or until
the driver door is opened. The
power windows will continue to work
for up to 10 minutes or until any
door is opened.
Starting the Engine
Move the shift lever to P (Park) or
N (Neutral). The engine will not start
in any other position. To restart the
engine when the vehicle is already
moving, use N (Neutral) only.
Notice: Do not try to shift to
P (Park) if the vehicle is moving.
If you do, you could damage the
transmission. Shift to P (Park)
only when the vehicle is stopped.
Starting Procedure
1. With your foot off the accelerator pedal, turn the ignition to START.
When the engine starts, let go of
the key. The idle speed will slow
down as the engine warms. Do
not race the engine immediately
after starting it. Operate the
engine and transmission gently
to allow the oil to warm up and
lubricate all moving parts. The vehicle has a
Computer-Controlled Cranking
System. This feature assists in
starting the engine and protects
components. If the ignition key is
turned to the START position,
and then released when the
engine begins cranking, the
engine will continue cranking for
a few seconds or until the
vehicle starts. If the engine does
not start and the key is held in
START, cranking will be stopped
after 15 seconds to prevent
cranking motor damage. To
prevent gear damage, this
system also prevents cranking if
the engine is already running.
Engine cranking can be stopped
by turning the ignition switch to
the ACC/ACCESSORY or
LOCK/OFF position.
