Automatic Operation
AUTO (Automatic):The system
automatically controls fan speed, air
delivery, and air conditioning in
order to heat or cool the vehicle to
the desired temperature. When the
indicator light is on, the system is in
full automatic operation. If the air
delivery mode or fan setting is
manually adjusted, the auto
indicator turns off and displays will
show the selected settings.
1. Press the AUTO button.
2. Adjust the temperature to a comfortable setting between
21°C (70°F) and 27°C (80°F).
Choosing the coldest or warmest
temperature setting will not
cause the system to heat or cool
any faster.
To avoid blowing cold air in cold
weather, the system delays
turning on the fan until warm air is available. The system starts
out blowing air at the floor, but
can automatically change modes
as the vehicle warms up to
maintain the chosen temperature
setting. The length of time
needed for warm up depends on
the outside temperature and the
length of time that has elapsed
since the 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.
English can be changed to metric
units through the Driver Information
Center (DIC). See Driver
Information Center (DIC) on
page 5‑27.
Q/R(Temperature Control): The
temperature can be adjusted
separately for the driver and the
passenger. Press to increase or
decrease the automatic temperature
settings. PASS (Passenger Climate
Control):
Press to set a different
temperature for the passenger.
Then adjust the passenger
temperature buttons to a
comfortable setting.
Pressing the PASS button again
automatically sets the passenger's
temperature to the driver's setting.
Turning the passenger's
temperature display off does not
shut the passenger's climate control
system off.
Manual Operation
O(Power): Press to turn the
climate control system on or off.
When the climate control system is
turned off the air inlet defaults to
outside air.
D C(Fan Control): Press the
buttons to increase or decrease the
fan speed. Pressing either button
cancels automatic fan control. Press
AUTO to return to automatic

operation. The blower may reduce
during an Onstar®session to limit
background noise.
If the airflow seems low when the
fan speed is at the highest setting,
the passenger compartment air filter
might need to be replaced. For more
information, see Passenger
Compartment Air Filter on page 8‑6.
H G(Air Delivery Mode Control):
Press the buttons to change the
direction of the airflow. The current
mode appears in the display screen.
Changing the mode cancels the
automatic air delivery. Press AUTO
to return to automatic operation.
The outboard air outlets always
receive some airflow in every mode,
except defrost.
To change the current mode, select
one of the following:
Y(Vent): Air is directed to the
instrument panel outlets.
\(Bi-Level): Air is divided
between the instrument panel
outlets and the floor outlets. In automatic operation, cooler air is
directed to the upper outlets and
warmer air to the floor outlets.
[(Floor):
Air is directed to the
floor outlets, with some air directed
to the windshield and outboard
outlets.
-(Defog): This mode clears the
windows of fog or moisture. Air is
directed to the windshield, floor, and
side window outlets. 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 is
selected while in defog mode, it is
cancelled after 10 minutes.
0(Defrost): This mode clears the
windshield of fog or frost more
quickly. Air is directed to the
windshield, with some air directed to
the side windows. In this mode, the
system automatically turns off
recirculation and runs the air-conditioning compressor, unless
the outside temperature is at or
below freezing.
This mode can also cause the fan
speed and air temperature to
increase.
#(Air Conditioning):
Press to
turn the air conditioning system on
or off and override the automatic
system. When in AUTO, the air
conditioning compressor comes on
automatically, as needed.
The air conditioning system
removes moisture from the air, so
water might drip under the vehicle
while idling or after turning off the
engine. This is normal.
M(Recirculation): Press to turn
on recirculation. An indicator light
comes on. Air is recirculated inside
the vehicle. It helps to quickly cool
the air inside the vehicle or prevent
outside air and odors from entering.
Press the AUTO button to have the
system select the best air delivery
mode for the temperature setting.

Recirculation is not available in the
defrost mode and automatically
turns off 10 minutes after defog is
selected. This helps to limit window
fogging in the vehicle.
Using recirculation for long periods
of time could 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 outside
air or press the auto button.
F(Outside Air):Press to turn
on the outside air. An indicator light
turns on. The outside air mode pulls
fresh air from outside the vehicle.
Outside air is always selected in
defrost mode to prevent fogging.
Rear Window Defogger
The rear window defogger uses a
warming grid to remove fog or frost
from the rear window. It only works
when the ignition is in ON/RUN.
=(Rear Window Defogger):
Press to turn the rear window
defogger on or off. The rear window defogger stays on
for about 15 minutes, before turning
off if the vehicle is moving at a
slower speed. At higher speeds, the
rear window defogger may stay on
continuously. With each additional
press, the defogger runs for about
10 minutes. The defogger can also
be turned off by turning off the
engine.
The heated outside rearview mirrors
turn on when the rear window
defogger button is on and helps to
clear fog or frost from the surface of
the mirrors. See
Heated Mirrors on
page 2‑27.
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 the
radio's ability to pick up stations
clearly. The repairs would not be
covered by the vehicle warranty.
z/{(Heated and Ventilated
Seats, If Equipped): Press to heat
or ventilate the seat. See Heated
and Ventilated Front Seats on
page 3‑9.
Remote Start Climate Control
Operation: For vehicles with
remote vehicle start, the climate
control system automatically heats
and cools the vehicle based on the
temperature inside and outside of
the vehicle. The climate control
displays will be blank. See Remote
Vehicle Start on page 2‑10.
In cold weather the windshield
defroster and/or rear window
defogger automatically turn on.
If the vehicle has heated seats, they
will also turn on.
When the ignition is turned to ON/
RUN, the climate control system
returns to the settings used before
the vehicle was last turned off. The
heated seats will turn off,
if equipped.

Sensors
The solar sensor on the instrument
panel, near the windshield, monitors
the solar heat.
The interior temperature sensor, on
the instrument panel to the right of
the steering wheel, measures the
temperature of the air inside the
vehicle.The climate control system uses the
information from these sensors to
adjust the fan speed and the air
delivery, in order to maintain the
selected temperature. 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.
Air Quality Sensor
For vehicles with an air quality
sensor, the climate control system
adjusts to limit some exhaust fumes
from being pulled inside your
vehicle.
Press the AUTO button on the
climate control to activate the air
quality sensor. The recirculation
indicator light comes on when poor
quality air is detected. The air
quality sensor will not maintain
recirculation for an extended period
to prevent the air inside the vehicle
from becoming too dry or stuffy.
Under certain conditions, the air
quality sensor will not activate, such
as during cold weather or with
extreme odors. Press
Mto
activate recirculation.
The air quality sensor system does
not protect against carbon monoxide
(CO), which you cannot see or
smell. See Engine Exhaust on
page 9‑24.

Air Vents
Use the air outlets in the center and
on the side of the instrument panel
to direct the airflow. Use the
thumbwheels near the air outlets to
open or close off the airflow.
Operation Tips
.Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
block the flow of air into the
vehicle.
.Keep the path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
.Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
Maintenance
Passenger Compartment
Air Filter
The passenger compartment air
filter traps most of the dust and
pollen from the air entering the
vehicle. The filter will need to be
changed periodically. See
Maintenance Schedule on
page 11‑3.
Using the climate control system
without the passenger air filter
installed could let water or other
debris enter the system. This could
cause a water leak or noises. Make
sure a new air filter is installed after
removing the old one.
The passenger compartment air
filter is under the hood below the
windshield wiper arm and the
screen on the passenger side of the
vehicle. SeeEngine Compartment
Overview on page 10‑5 for more
information on location.
