To avoid blowing cold air in cold weather, the
system will delay turning on the fan until warm
air is available. The length of delay depends on
the engine coolant temperature. Pressing the
fan switch will override this delay and change
the fan to a selected speed.
O(On/Off):Press this button to turn off the
climate control system. Outside air will still enter
the vehicle, and will be directed to the oor.
This direction can be changed by pressing the
mode button. Recirculation can be selected once
you have selected vent or bi-level mode. The
temperature can also be adjusted using either
temperature button. If you adjust the air delivery
mode or temperature settings with the system
off, the display will illuminate brie y to show
you the settings and then return off. Press the
on/off button or the up down arrows on the
fan switch, the defrost button, AUTO button,
or the air conditioning button to turn the system
on when it is off.
Manual Operation
You may manually adjust the air delivery mode
or fan speed.
y9z(Fan):The buttons with the fan symbols
allow you to manually adjust the fan speed.
Press the up arrow to increase fan speed and
the down arrow to decrease fan speed.
Pressing one of these buttons when the system
is off will turn the system on. Pressing one of these
buttons when in automatic control will place the
fan under manual control. The fan setting will
remain displayed and the AUTO light will turn off.
The air delivery mode will remain under
automatic control.
yNz(Mode):Press the mode up and down
buttons to manually change the direction of
the air ow in your vehicle. Repeatedly press the
button until the desired mode appears on the
display. Pressing one of these buttons when the
system is off will change air delivery mode without
turning the system on. Pressing one of these
buttons when in automatic control will place the
mode under manual control.

In order to prevent false temperature readings
at startup, the displayed temperature will not
change until the following occurs:
Vehicle speed is above 10 mph (16 kmh)
for 5 minutes.
Vehicle speed is above 32 mph (51 kmh)
for 2 and a half minutes.
The climate control system uses the information
from these sensors to maintain your comfort
setting by adjusting the outlet temperature, fan
speed, and the air delivery mode. The system
may also supply cooler air to the side of the
vehicle facing the sun. The recirculation mode
will also be used as needed to maintain cool
outlet temperatures.
Defogging and Defrosting
Fog on the inside of the 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 mode up and down arrows to select the
defog or defrost modes.
-(Defog):The defog mode is used to clear
the windows of fog or moisture and warm
the passengers. This mode directs air to the
windshield, oor outlets, and side window vents.
When you select this mode, the system turns
off recirculation and runs the air conditioning
compressor unless the outside temperature is
close to freezing. The recirculation mode cannot
be selected while in the defog mode. Do not
drive the vehicle until all the windows are clear.
0(Defrost):Press this button to remove fog
or frost from the windshield more quickly.
This mode directs a portion of the air to the
windshield and side window vents and some to
the oor vents. In this mode, the system will
automatically force outside air into your vehicle.
The recirculation mode cannot be selected
while in the defrost mode. The air conditioning
compressor will run automatically in this setting,
unless the outside temperature is close to
freezing. Do not drive the vehicle until all the
windows are clear.

If the system fails to turn on or activate, the
StabiliTrak®light along with one of the following
messages will be displayed on the Driver
Information Center (DIC): TRACTION CONTROL
OFF, SERVICE TRACTION CONTROL,
STABILITRAK OFF, SERVICE STABILITRAK.
If these DIC messages appear, make sure
the StabiliTrak
®system has not been turned off
using the StabiliTrak®on/off button. Then turn the
steering wheel clockwise from the nine o’clock
position to the three o’clock position. If this clears
the message(s), your vehicle does not need
servicing. If this does not clear the message(s),
then turn the vehicle off, wait 15 seconds, and then
turn it back on again to reset the system. If any
of these messages still appear on the Driver
Information Center (DIC), your vehicle should be
taken in for service. For more information on
the DIC messages, seeDriver Information
Center (DIC) on page 257.The StabiliTrak
®light
will ash on the
instrument panel cluster
when the system is
both on and activated.
You may also feel or hear the system working;
this is normal.
The traction control
disable button
is located on
the instrument
panel below the
climate controls.
The traction control part of StabiliTrak
®can
be turned off by pressing and releasing the
StabiliTrak
®button if both systems (traction control
and StabiliTrak®) were previously on. To disable
both traction control and StabiliTrak®, press
and hold the button for ve seconds.

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 (NHTSA), 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 (UTQG)
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 speci ed
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 signi cantly 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 speci ed
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.
