Climate Controls
Dual Climate Control System
The heating, cooling, defrosting, and ventilation for the
vehicle can be controlled with this system.
Automatic Operation
The climate control system automatically adjusts the
air temperature, air delivery mode, fan speed, and air
conditioning for best comfort in the vehicle. To activate
the automatic system:
AUTO (Automatic Mode):
1. Turn the fan and mode controls to the AUTO
position. This also sets the recirculation mode
to automatic operation on the display.
2. Press the up or down arrows to adjust the
temperature to a comfortable setting between
70°F (21°C) and 80°F (27°C).
3. Allow the system time to stabilize. This might take
several minutes in very hot or cold weather. Then
adjust the temperature, as needed for best comfort.
Choosing the coldest or warmest temperature setting
will not cause the system to heat or cool any faster.
In cold weather, the system starts at reduced fan
speeds to avoid blowing cold air into the vehicle until
warmer air is available. The automatic system starts
out blowing air at the oor, but changes modes
automatically as the vehicle warms up to maintain
the chosen temperature setting. The length of time
needed to warm the interior depends on the outside
temperature and the amount of time that has passed
since the vehicle was last driven. Dual Climate Control System

«ª(Driver’s Temperature Controls):Press the up
or down buttons closest to the driver to manually increase
or decrease the temperature inside the vehicle.
«ª(Passenger’s Temperature Controls):Press
the up or down buttons closest to the passenger to
manually increase or decrease the temperature for
the front passenger. If the passenger’s climate control
system is off, pressing either of these buttons turns it on.
Manual Operation
9(Fan):Turn the left control to adjust the fan speed
manually if the automatic setting is higher or lower than
desired. The fan speed remains at this level until you
return to AUTO or adjust to a different level. In the
automatic position, the blower might go to a lower speed
during an OnStar
®session to limit the background noise.
To change the current mode, select one of the following
positions using the right control:
AUTO:Turn the control to this position to turn on the
automatic delivery mode operation.
F(Vent):Turn the control to this position so that air is
directed to the instrument panel outlets.
*(Bi-Level):Turn the control to this position so
that the air is directed to the instrument panel outlets
and the oor outlets. The temperature of the air to
the oor will be warmer than the air to the upper outlets.
7(Floor):Turn the control to this position so that most
of the air is directed to the oor outlets with some air
directed to the outboard outlets, side window outlets,
and defroster outlet.
W(Defog):Turn the control to this position so that air
is directed between the windshield and oor outlets,
with some air going to the outboard outlets and
side window outlets. More information of defogging
can be found later in this section.
0(Defrost):Turn the control to this position so
that most of the air is directed to the windshield with
some air going to the side window outlets. More
information on defrosting can be found later in this
section.
O(On/Off):Press this button to turn the climate
control system on or off. While off, adjusting any button or
control, except recirculation and rear window defog turns
the system back on. The air inlets default to outside air
when the climate control system is turned off.
3-24

PASS (Passenger’s Climate Control):Press this
button to turn the passenger’s climate control system on
or off. Then press the up or down buttons to choose the
desired setting. Pressing the button again automatically
sets the passengers temperature to the drivers setting.
Turning the passenger’s temperature display off does not
turn off the climate control system for the passenger.
Recirculation Operation
There are three options for bringing air into the
climate control system. They are controlled by
pressing the center button on the climate control panel.
The climate control display indicates one of the following
three modes:
9(Auto Air Inlet):This mode lets the automatic
climate control system choose the best air inlet position
for cooling or warming the vehicle. To have full automatic
climate control, the fan and mode controls must be set to
the AUTO position. Generally, recirculation will only
automatically be selected on hot days.Your vehicle may have an optional Air Quality Sensor.
To activate the air quality sensor, the auto air inlet setting
must be used. For more information, see Air Quality
Sensor found later in this section.
?(Recirculation):This mode recirculates air inside
the vehicle and keeps outside air from coming into
the vehicle. It can be used to help cool the vehicle more
quickly or to prevent odors from entering the vehicle.
Recirculation is not available in the defrost mode.
It is also cancelled when oor or defog mode is selected.
In some conditions using recirculation for long periods
of time can cause the air inside the vehicle to become
too dry or stuffy. To prevent this from happening,
after the air in the vehicle has cooled, select auto
air inlet or outside air.
:(Outside Air):This mode pulls fresh air from
outside the vehicle. Outside air is always selected
in defrost mode to prevent fogging.
3-25

Air Quality Sensor:Your vehicle may have an air
quality sensor to help limit the climate control system
from pulling in irritating or harmful exhaust fumes from
other vehicles. This sensor, when active, monitors the
air quality in front of your vehicle and switches to air
recirculation when poor quality air is detected outside
your vehicle. The air quality sensor does not activate
due to organic odors like skunk, and may not activate on
many chemical-related odors. If you wish to limit these
types of odors, manually select recirculation.
To activate the air quality sensor, if your vehicle has one,
select the Auto Air Inlet on your climate control display.
The word AUTO is shown in the center of the display
under the outline shape of a vehicle. While the air quality
sensor senses poor quality air, the recirculation graphic
appears above the AUTO symbol.
Under some conditions, the air quality sensor system
does not operate. In cold weather, the system might
not be active (even if AUTO is displayed) because of
concerns of fogging your windows, which may occur by
activating recirculation mode. Also, the air quality sensorsystem does not remain in recirculation mode for
extended periods of time that could cause stuffy or very
dry conditions in the vehicle. Following a poorly running
vehicle for an extended period of time may not keep
recirculation active indenitely.
The air quality sensor system does not protect against
carbon monoxide (CO), which you cannot see or smell.
SeeEngine Exhaust on page 2-39.
Air Conditioning
#
(Air Conditioning):Press this button to turn the
air conditioning on or off, and override the automatic
system. When selecting the AUTO fan or AUTO mode,
the air conditioning compressor comes on automatically,
as necessary.
The air conditioning system removes moisture from the
air, so water might drip underneath the vehicle while
idling or after turning off the engine. This is normal.
3-26

Sensors
There is a solar sensor located on top of the instrument
panel, near the windshield.There is an interior
temperature sensor
located below the climate
control system next to
the steering wheel.
An ambient sensor is located behind the grille in front of
the vehicle.
These sensors help the climate control system
automatically control the temperature setting. The
system can 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.
Do not cover any of the sensors or the climate control
system might not work properly.
3-27

Defogging and Defrosting
Fog on the inside of windows is a result of high humidity
(moisture) condensing on the cool window glass.
This can be minimized if the climate control system
is used properly. There are two modes to clear fog
from the windshield.
W(Floor/Defog):Use this mode to clear the windows
of fog and warm the passengers. The system turns off
recirculation and runs the air conditioning compressor
unless the outside temperature is at or below freezing.
If recirculation mode is selected while using the defog
mode, the system recirculates air initially but returns to
the fresh air mode after 10 minutes.
0(Defrost):Use this mode to remove fog or frost
from the windshield more quickly. When selected, the
system turns off recirculation and runs the air conditioning
compressor, unless the outside temperature is at or
below freezing.
Do not drive the vehicle until all the windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press the center of the right
control to turn the rear window defogger on or off.
Be sure to clear as much snow from the rear window
as possible. The rear window defogger turns off
about 20 minutes after the button is rst pressed if the
vehicle is moving at slower speeds. At higher vehicle
speeds, the rear defogger can stay on continuously.
Each additional press runs the defogger for about
10 minutes.
The heated outside rearview mirrors also heat to help
clear fog or frost from the surface of the mirror when the
rear window defogger is on.
Notice:Do not use a razor blade or sharp object to
clear the inside rear window. Do not adhere anything
to the defogger grid lines in the rear glass. These
actions may damage the rear defogger. Repairs
would not be covered by your warranty.

Outlet Adjustment
Use the knobs located in the center of each outlet to
change the direction of the airow. Use the thumbwheels
to open or close the outlets.
Operation Tips

Clear away any ice, snow, or leaves from the air
inlets at the base of the windshield that could
block the ow of air into the vehicle.
Use of non-GM approved hood deectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside of the vehicle more
effectively.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment
air lter might need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-30.
Set the climate control system to AUTO fan and
mode and then adjust the temperature setting
up or down a few degrees for best comfort.
Rear Air Conditioning System
If your vehicle has the rear air conditioning system it
has two fan speed selectors. One fan speed selector is
located in the front overhead console and the other is
located in the headliner above the second row seats.
The rear air conditioning system is designed to provide
cooled air only.
To operate the rear system using the front control, just
turn the knob to the fan position you want.
To use the rear control, rst turn the front control to
AUX, then the rear control can be used to increase and
decrease the airow.Front Control

Notice:Do not repeatedly brake or accelerate
heavily when the TCS is off. You could damage your
vehicle’s driveline.
When the TCS is switched off on AWD vehicles, you
may still feel the system working. This is normal
and necessary with the AWD hardware on your vehicle.
You should turn the system off if your vehicle ever
gets stuck in sand, mud or snow and rocking the vehicle
is required. SeeRocking Your Vehicle to Get It Out
on page 4-33andIf Your Vehicle is Stuck in Sand, Mud,
Ice, or Snow on page 4-32for more information. See

Press this button, located
below the climate control
system, to enable/disable
the tow/haul mode.
A light on the instrument
panel will illuminate to
indicate that tow/haul
mode has been selected.
The vehicle will automatically turn off tow/haul every
time it is started.
Driving with tow/haul activated without a heavy load or
with no trailer will cause reduced fuel economy and
unpleasant engine and transmission driving
characteristics, but will not cause damage.Operating the vehicle in tow/haul when lightly loaded or
with no trailer at all will not cause damage. However,
there is no benet to the selection of tow/haul when the
vehicle is unloaded. Such a selection when unloaded
may result in unpleasant engine and transmission driving
characteristics and reduced fuel economy. Tow/haul
is recommended only when pulling a heavy trailer or a
large or heavy load.
Weight of the Trailer
How heavy can a trailer safely be?
It depends on how you plan to use your rig. For
example, speed, altitude, road grades, outside
temperature and how much your vehicle is used to pull
a trailer are all important. It can also depend on any
special equipment that you have on your vehicle,
and the amount of tongue weight the vehicle can carry.
See “Weight of the Trailer Tongue” later in this
section for more information.
