Dual Automatic Climate
Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):Press the AUTO button for
automatic control of the inside temperature, the air
delivery mode and the fan speed.
1. Press the AUTO button.2. Adjust the temperature to 75°F (24°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.
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
Pressing the FAN or AIR FLOW buttons cancels
automatic operation and places the system in
manual mode. Press the AUTO button to return to
automatic operation.
TEMP (Temperature):To manually adjust the
temperature inside the vehicle, push the TEMP arrow.
Push the TEMP up arrow for warmer temperature
settings and the TEMP down arrow for cooler
temperature settings. The setting will be shown on the
display. The display will return to the outside
temperature after a few seconds.
9FAN:Pressing the FAN button will display and hold
the current fan speed while in manual mode. If you
want the fan to run at a lower speed, push the down
arrow on the FAN button. If you want to increase the fan
speed, push the up arrow on the FAN button.
AIR FLOW:Pressing the AIR FLOW button will display
and hold the current setting while in manual mode.
Use the up and down arrows on the AIR FLOW button
to cycle through the available modes.
WINDSHIELD-FLOOR:This mode directs most of
the airow to the windshield with some airow to
the outboard outlets (for the side windows) and the
oor outlets.
MID:This mode directs airow through the
instrument panel outlets.
MID-FLOOR:This mode directs airow through
both the oor and the instrument panel outlets.
There is also a small amount of air directed to the
windshield and the outboard outlets (for the
side windows).
FLOOR:This mode directs most of the airow to
the oor outlets with some directed to the outboard
outlets (for the side windows) and the windshield.
OFF:Press the OFF button once to turn off the
passenger climate control, if it has been activated.
Pressing the OFF button a second time will turn off the
main system. The outside temperature will be shown
on the display when the system is off.
VENT (Flow-Through Ventilation):Pressing the VENT
button allows outside air to ow through your vehicle
without the air conditioning compressor working. To turn
VENT off, press the VENT button again.
Selecting the VENT and AUTO buttons at the same
time allows the system to control the airow
automatically without using the air conditioning
compressor or the recirculation mode.
3-28

RECIRC (Recirculation):Press this button to limit the
amount of outside air coming into 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 turn the
recirculation mode on or off. When the button is
pressed, an indicator light will come on. The recirculation
mode cannot be used with the FRONT defrost or
VENT modes.
On hot days, open the windows to let hot air escape;
then close them. This helps to reduce the time it takes
for your vehicle to cool down. It also helps the system
to operate more efficiently.
For quick cool down on hot days, press the AUTO
button and the system will automatically enter
recirculation mode and the temperature will be at the full
cold position for maximum cooling.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become too
dry. To prevent this from happening, after the air in
your vehicle has cooled, turn the recirculation mode off.
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.Sensors
The solar sensor on your vehicle monitors the solar
radiation and the air inside of your vehicle, then uses the
information to maintain the selected temperature by
initiating needed adjustments 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 solar sensor located in the
center of the instrument panel, near the windshield, or the
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.
1FRONT (Defrost):Press the FRONT button to
defrost the windshield by directing airow toward the
windshield and outboard outlets for the side windows. To
turn off FRONT, press the AUTO or AIR FLOW buttons.
If the AIR FLOW up button is pressed while in the FRONT
defrost mode, the system will direct the air toward the
instrument panel outlets. If the AIR FLOW down button is
pressed while in the FRONT defrost mode, the system
will direct the air toward the oor, and the FRONT defrost
mode will cancel. 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 (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.
At speeds above 35 mph (55 km/h), the defogger will
operate continuously until you press the REAR
button again. After 10 minutes of driving below 35 mph
(55 km/h), the defogger will turn off automatically. If
you need additional warming time, push the button
again. The system will then operate for ve minutes
before going off by itself.
If your vehicle has heated outside rearview mirrors, the
mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defogger
button is pressed.
Notice:Using a razor blade or sharp object to clear
the inside rear window may damage the rear
window defogger. Repairs would not be covered by
your warranty. Do not clear the inside of the rear
window with sharp objects.
Passenger Temperature Control
If your vehicle has this feature, then the driver and the
front-seat passenger can select separate temperature
settings. This feature allows the passenger to select
a temperature that is 5°F (3°C) warmer or cooler than
the driver’s selected temperature. The control is located
on the passenger’s door armrest.
Press the red button for a warmer temperature or the
blue button for a cooler temperature. Press the
OFF button on the main system once to turn off the
passenger’s temperature control. Press the OFF button
twice to turn off the entire climate control system.

Outlet Adjustment
Use the levers located in the middle of the front outlets
to change the direction of the airow.
In vehicles equipped with rear seat outlets, you can
adjust the direction of the airow using the lever in the
center of each outlet. Use the thumbwheel located
between the outlets to turn them on and off.
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.
Steering Wheel Climate Controls
If your vehicle has this
feature, you can control
the temperature function
by using the switch located
on your steering wheel.
wTEMPx(Temperature):Press the up or
down arrow on this switch to increase or decrease
the temperature.

Climate Controls Personalization
If your vehicle is equipped with this feature, up to
two drivers are able to store and recall climate control
settings for the temperature, the fan speed and the
direction of the airow.
Memory buttons 1 and 2 are located on the driver’s
door armrest and correspond to the numbers 1
or 2 found on the back of each remote keyless
entry transmitter.
To store settings, do the following:
1. Select the desired temperature, fan speed and
airow mode. If desired, a separate temperature
setting may also be selected for the front seat
passenger. For information on how to do this, see

Uniform Tire Quality Grading
Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:
Treadwear 200 Traction AA Temperature A
The following information relates to the system
developed by the United States National Highway
Traffic Safety Administration, which grades tires by
treadwear, traction and temperature performance. (This
applies only to vehicles sold in the United States.)
The grades are molded on the sidewalls of most
passenger car tires. The Uniform Tire Quality Grading
system does not apply to deep tread, winter-type
snow tires, space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12 inches
(25 to 30 cm), or to some limited-production tires.
While the tires available on General Motors passenger
cars and light trucks may vary with respect to these
grades, they must also conform to federal safety
requirements and additional General Motors Tire
Performance Criteria (TPC) standards.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specied government test course.
For example, a tire graded 150 would wear one and
a half (1.5) times as well on the government course as
a tire graded 100. The relative performance of tires
depends upon the actual conditions of their use,
however, and may depart signicantly from the norm
due to variations in driving habits, service practices and
differences in road characteristics and climate.
Traction – AA, A, B, C
The traction grades, from highest to lowest, are AA, A,
B, and C. Those grades represent the tire’s ability
to stop on wet pavement as measured under controlled
conditions on specied government test surfaces of
asphalt and concrete. A tire marked C may have poor
traction performance. Warning: The traction grade
assigned to this tire is based on straight-ahead braking
traction tests, and does not include acceleration,
cornering, hydroplaning, or peak traction characteristics.
