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.

Sensors
There is a solar sensor located on the instrument
panel, near the windshield.There is also an interior
temperature sensor
located to the right of
the steering wheel
on the instrument panel.
These sensors monitor the solar radiation and the
air inside your vehicle, they use the information to
maintain the selected temperature by adjusting to
the temperature, the fan speed, and the air delivery
system. The system may also supply cooler air to
the side of the vehicle facing the sun. The
recirculation mode will also be activated, as
necessary. Do not cover the sensors or the
automatic climate control system will not work
properly.

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.

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.
