Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, and ventilation for the vehicle.
Automatic Operation
AUTO (Automatic):When this button is pressed
and the temperature is set, the system will
automatically control the inside temperature, the air
delivery mode, the air conditioning compressor, and
the fan speed. AUTO will appear on the display.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable
setting between 70°F (21°C) and 80°F (27°C).Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. If you set the system at the warmest
temperature setting, the system will remain in
manual mode at that temperature and it will not
go into automatic mode.
In cold weather, the system will start at
reduced fan speeds to avoid blowing cold air
into your vehicle until warmer air is available.
The system will start out blowing air at
the oor but may change modes automatically
as the vehicle warms up to maintain the
chosen temperature setting. The length of time
needed for warm up will depend on the
outside temperature and the length of time
that has elapsed since your vehicle was
last driven.
3. Wait for the system to regulate. This may take
from 10 to 30 minutes. Then adjust the
temperature, if necessary.
You can switch from English to metric units through
the Driver Information Center (DIC). If you have the
Base audio system, seeDIC Main Menu on
page 228. If you have the Navigation system, see
“Setup Menu” in the Index of the Navigation System
Owner Manual.

The air-conditioning system removes moisture
from the air, so you may sometimes notice a small
amount of water dripping underneath your
vehicle while idling or after turning off the engine.
This is normal.
Do not cover the solar sensor located in the
center of the instrument panel, near the
windshield. For more information on the solar
sensor, see “Sensors” later in this section.
Manual Operation
yNz(Mode):Pressing the mode switch and
changing the mode cancels automatic operation
and places the system in manual mode. Press

The outboard air outlets will always receive airow
regardless of the mode selected. SeeOutlet
Adjustment on page 194to change this airow
from the outboard outlets.To change the current mode, select one of the
following:
Y(Vent):This mode directs air to the instrument
panel outlets.
\(Bi-Level):This mode directs approximately
half of the air to the instrument panel outlets,
and then directs most of the remaining air to the
oor outlets. In automatic operation, cooler air
is directed to the upper outlets and warmer air to
the oor outlets.
[(Floor):This mode directs most of the air to
the oor outlets with some air directed to the
outboard outlets (for the side windows), and a little
air directed to the windshield.
The mode switch can also be used to select the
defog mode. Information on defogging and
defrosting can be found later in this section.
yAz(Fan):Press this switch to increase or

lter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 195andScheduled Maintenance on
page 462.
h(Recirculation):This mode keeps outside
air from coming in the vehicle. It can be used
to prevent outside air and odors from entering your
vehicle or to help heat or cool the air inside your
vehicle more quickly. Press this button to
switch between recirculation and fresh air. Press
the auto button to have the system select the best
air delivery mode for your temperature setting.
Recirculation is not available in the defrost mode
and will automatically turn off after 10 minutes
when defog is selected.
Using recirculation for long periods of time may
cause the air inside your vehicle to become too dry
or stuffy. To prevent this from happening, after
the air in your vehicle has cooled, turn the
recirculation mode off or press the auto button.
((Heated Seats):Press this button to turn on

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 your windshield.
Use the defog mode to clear the windows of fog
or moisture and warm the passengers. Use
the defrost mode to remove fog or frost from the
windshield more quickly.
yNz(Mode):Press this button until defog
appears on the display.
-(Defog):This mode directs the air between the
windshield, oor outlets and side windows.
When this mode is selected, 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 in defog mode, it will be cancelled after
10 minutes.
If there is fog on the side windows, turn the
thumbwheel on the outboard outlets to the side
window defog position. SeeOutlet Adjustment on
page 194for more information.
0(Defrost):Pressing defrost directs most of the
air to the windshield, with some air directed to
the side windows. In this mode, the system
will automatically turn off recirculation and run the
air-conditioning compressor, unless the outside
temperature is at or below freezing.
This mode may also cause the fan speed and air
temperature to increase.
If there is fogging on the side windows, turn the
thumbwheel on the outboard outlets to the
side window defog position. SeeOutlet Adjustment
on page 194for more information. 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.
The rear window defogger will only work when the
ignition is in ON.
=(Rear Window Defogger):Press this button
to turn the rear window defogger on or off.
Be sure to clear as much snow from the rear
window as possible.
193

The rear window defogger will turn off about
10 minutes after the button is pressed, but if the
vehicle’s speed is above 30 mph (48 km/h),
the rear defogger will stay on continuously.
If turned on again, the defogger will only run for
about ve minutes before turning off. The defogger
can also be turned off by pressing the button
again or by turning off the engine.
The heated outside rearview mirrors will heat to
help clear fog or frost from the surface of the mirror
when the rear window defogger button is on.
SeeOutside Heated Mirrors on page 141.
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.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.
j(Side Window Defog):Turn the thumbwheel
to this symbol to use the side window defog
setting. The air coming through the outlets will be
directed toward the side windows to clear fog.
k(Open):Turn the thumbwheel to this symbol to
open the outlets completely and allow the
maximum amount of air to enter your vehicle.
A small amount of air will still be directed to the
side windows.
l(Closed):Turn the thumbwheel to this symbol
to close the outlets and minimize the amount
of air entering the vehicle.

Operation Tips

Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the ow of air into your 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
your vehicle more effectively.
Passenger Compartment Air Filter
The passenger compartment air lter traps most of
the pollen from the air entering your vehicle.
Like your vehicle’s engine air cleaner/lter, it needs
to be changed periodically. SeeScheduled
Maintenance on page 462.
Using the climate control system without the
passenger air lter installed may allow water or
other debris to enter the system. This could cause
a water leak or noises. Make sure to install a
new air lter after removing the old one.The passenger compartment air lter is located
underneath the hood below the windshield
wiper arm on the passenger’s side of the vehicle.
SeeEngine Compartment Overview on page 342
for more information on location.
Use the procedure listed below to replace the
passenger compartment air lter:
1. Turn the ignition to ON with the engine off.
2. Turn on the windshield wipers and turn them
off again when the wipers are straight on the
windshield.
This allows you access to the leaf screen.
The passenger compartment air lter is
located under the leaf screen.
195

3. Open the hood to access the engine
compartment. SeeHood Release on page 341
for more information.
4. Remove the four screws that hold the leaf
screen in place and lift off the screen by
lifting and sliding toward the center of
the vehicle.
5. Pull out on the two tabs located on each end
of the lter cover.
6. Lift the lter cover off by pulling it straight
upward.
7. Remove the old lter and insert a new one.
Make sure the arrow on the lter is pointing
toward the passenger compartment.
SeeNormal Maintenance Replacement Parts
on page 475for the correct part number
for the lter.
8. Reverse Steps 1 through 6 to reinstall
the cover.Steering Wheel Climate
Controls (CTS)
Your vehicle may have four controls that can be
programmed for use with the climate control
system.
The controls are located
on the left side of the
steering wheel.
SeeRecongurable Steering Wheel Controls
(SWC) (CTS) on page 169for more information on
programming these controls.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages on
your vehicle. The pictures help to locate them.
Warning lights and gages can signal that something
is wrong before it becomes serious enough to
cause an expensive repair or replacement. Paying
attention to the warning lights and gages could also
save you or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As
the details show on the next few pages, some
warning lights come on briey when you start the
engine just to let you know they are working. If
you are familiar with this section, you should
not be alarmed when this happens.Gages can indicate when there may be or is a
problem with one of your vehicle’s functions. Often
gages and warning lights work together to let you
know when there is a problem with your vehicle.
When one of the warning lights comes on and
stays on as you are driving, or when one of the
gages shows there may be a problem, check
the section that tells you what to do about
it. Please follow this manual’s advice. Waiting to
do repairs can be costly and even dangerous.
So please get to know your vehicle’s warning lights
and gages. They can be a big help.
Your vehicle may also have a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information Center
(DIC) on page 222for more information.
197

Speedometer and Odometer
The speedometer lets you see your speed in
either miles per hour (mph) or kilometers
per hour (km/h). The odometer shows how far
your vehicle has been driven, in either miles
(used in the United States) or kilometers (used in
Canada).
If your vehicle has to have a new odometer
installed, the new one may read the correct
mileage. This is because your vehicle’s computer
has stored the mileage in memory.
While the Driver Shift Control (DSC) feature is
active, the odometer will change to show the gear
range. SeeAutomatic Transmission Operation
on page 122for more information.
Trip Odometers
The trip odometer can record the number of miles
or kilometers traveled for up to two trips.
The trip odometer is part of the Driver Information
Center (DIC), for more information seeStatus
of Vehicle Systems on page 223.
For vehicles that have the navigation system,
see your Navigation System manual for more
information.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Notice:If you operate the engine with the
tachometer in the shaded warning area, your
vehicle could be damaged, and the damages
would not be covered by your warranty. Do not
operate the engine with the tachometer in
the shaded warning area.
