Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
FAN:Turn the left knob clockwise or counterclockwise
to increase or decrease the fan speed. Push this
knob to turn the fan on and off. The fan must be on in
order for the air conditioning compressor to run.
TEMP (Temperature Control):Turn the right knob
clockwise or counterclockwise to manually increase or
decrease the temperature inside your vehicle.To change the current mode, select one of the following:
6(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 some air directed
to the windshield.
)(Bi-Level):This mode directs about half of the air to
the instrument panel outlets, and then directs most of the
remaining air to the oor outlets. There is also a small
amount of air directed to the windshield and outboard
outlets (for the side windows). This mode directs cooler
air to the upper outlets and warmer air to the oor outlets.
H(Vent):This mode directs air to the instrument
panel outlets.
?RECIRC (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 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 mode.
3-27

#A/C (Air Conditioning):Press this button to turn
the air conditioning compressor on and off. When A/C is
pressed, an indicator light in the button will come on
to let you know that air conditioning is activated. If your
climate control system is off, you may also turn it
back on in vent mode by selecting the A/C button.
On hot days, open the windows to let hot inside
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, do the following:
1. Select the vent mode.
2. Select the recirculation mode.
3. Select A/C.
4. Select the coolest temperature.
5. Select the highest fan speed.
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.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 or frost 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.
Press one of the available mode buttons to select the
defog or defrost mode.
-(Defog):This mode directs most of the air to the
windshield and the oor outlets. A small amount of air is
also directed to the outboard outlets (for the side
windows). When you select this mode, the system turns
off recirculation and runs the air conditioning compressor
unless the outside temperature is at or below freezing.
The recirculation mode cannot be selected while in the
defog mode.

0FRONT (Defrost):Pressing this button directs
most of the air to the windshield and the outboard outlets
(for the side windows), with some air directed to the
oor outlets. When you select this mode, the system
turns off recirculation and runs the air conditioning
compressor unless the outside temperature is at
or below freezing. The recirculation mode cannot be
selected while in the FRONT defrost mode. Do not drive
the vehicle until all windows are clear.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
=REAR: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.
The rear window defogger will turn off about 10 minutes
after the button is pressed. If turned on again, the
defogger will only run for about ve minutes before
turning off. If you maintain a speed above 30 mph (48
km/h), the rear defogger will not turn off automatically to
help keep the rear glass clear. The defogger can also
be turned off by pressing the button again or by turning
off the engine.If your vehicle has outside heated 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.

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.
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 panel 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
Automatic Climate Control System on page 3-29.
2. Locate memory buttons 1 and 2 on the driver’s
door panel.
3. Press the memory button on the door panel that
corresponds to the number on the back of the
transmitter you are programming, until you hear two
beeps. The beeps conrm that your selection has
been saved and can now be recalled. For more
information on the memory feature, seeMemory
Seat and Mirrors on page 2-50.
Follow these steps each time you want to change the
stored settings.
To recall the climate control settings last stored on your
transmitter, press the unlock button on your remote
keyless entry transmitter and put the ignition in

Security Feedback
Delayed Locking
Perimeter Lighting
Memory Seats
Outside Curb View Assist Mirror
Driver ID
The DIC is used to program the personal choices of two
drivers. The drivers are recognized as DRIVER #1 and
DRIVER #2. You will let the DIC know which driver you
are by using your remote keyless entry transmitter or by
pressing the appropriate memory seat control button
located on the driver’s door or by choosing the driver with
the DIC. Each remote keyless entry transmitter was
preprogrammed to belong to DRIVER #1 or DRIVER #2.
Each transmitter may be programmed differently.When you press the unlock button on your transmitter,
the DIC will change driver numbers and the vehicle
will recall the personalization settings that were
last made to correspond to your transmitter, including
your radio and climate control settings. SeeClimate
Controls Personalization on page 3-35.
If you unlock the vehicle using your door key instead of
your transmitter, the DIC will not change drivers and
will recall the information from the last transmitter use or
the last driver change using the memory seat controls.
If this happens and you were not the last driver of
the vehicle, press your correct driver number on the
memory seat controls or press the unlock button on your
transmitter or select the personalization programming
mode and choose the correct driver number.
Use the following steps for personalization programming
instructions.

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.
