Automatic Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic): When both the mode knob and the
fan knob are in the AUTO mode and the temperature
is set, the system will automatically control the
inside temperature, the air delivery mode and the fan
speed.
1. Press both the mode and the fan knobs to place
2. Adjust the temperature to

display. 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 floor 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.
To change the automatic climate control display from an
English display to a metric display, push the
OFF
button located in the Driver Information Center (DIC) for
several seconds. The display in the
DIC will also
change from an English to a metric display.
To return to
an English display, repeat the procedure.
Manual Operation
FAN: Turn the right knob clockwise or counterclockwise
to increase or decrease the fan speed. Turning this
knob cancels automatic operation and places the system
in manual mode. Press the knob to return to automatic
operation.
Temperature Control: Maintain the temperature inside
the vehicle using the red and blue arrows located
below the digital display. Push the red arrow for a
warmer temperature level and the blue arrow for
a cooler temperature level. Your selected temperature
setting will be shown on the digital display for five
seconds, and then the outside temperature will be
displayed. To change
the current mode, use the left knob
to select
one of the following:
OFF: Turning the left knob to OFF will cause the fan to
turn
off and the airflow to be directed through the
floor outlets. The display will show the outside
temperature when the system is set to OFF.
/I‘ (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 floor outlets.
Some air may be directed toward the windshield.
In automatic operation, cooler air is directed to the upper
outlets and warmer air to the floor outlets.
I# (Floor): This mode directs most of the air to the
floor outlets with some air directed to the outboard
outlets (for the side windows) and some air directed to
the windshield.
The left knob can also be used to select the defog or
defrost mode. Information on defogging and defrosting
can be found later in this section.

Move the control between the rear outlets up to direct
airflow through the upper outlets. Move the control down
to direct airflow through the floor outlets. Adjust the
direction of the airflow with the levers located in
the center of each rear outlet.
Operation Tips
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into your vehicle.
Use of non-GM approved hood deflectors 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 airflow.
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
airflow 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 3-23.
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 confirm that your selection has
been saved and can now be recalled. For more
information
on the memory feature, see Memory
Seat
and Mkrors on page 2-48.
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
ACC (Accessory) or
ON. The settings will be recalled.

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 specified 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 significantly 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 specified 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, hydroplaninGr or peak traction characteristics.
