Climate Controls
Dual Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle. To avoid window fogging
on rainy and humid days at temperatures above
freezing, run the air conditioning compressor. Also, it is
best to avoid the use of recirculation mode except
when maximum air-conditioning performance is needed
for a short amount of time to avoid exterior odors
and fogging.

Automatic Operation
AUTO9(Automatic Fan):When this position is
selected on the fan control, the system will adjust the fan
speed. If the OnStar
®system is activated when this
position is selected, the climate control fan speed
will lower.
AUTO (Automatic Mode):
1. Turn the fan control to the AUTO position.
2. Turn the mode control to the AUTO position.
3. Adjust the temperature to a comfortable setting
between 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool any
faster. 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 to warm
the interior will depend on the outside temperature
and temperature of the vehicle.
4. Wait 20 to 30 minutes for the system to stabilize in
order for the system to regulate automatically. Then
adjust the temperature as necessary to nd your
comfort setting.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.
After your vehicle is started, the display will show the
interior temperature settings and the outside
temperature.
If the AUTO position is selected on the fan or mode
control, the system will automatically control the
air conditioning compressor. The A/C compressor will
run automatically even at cool outside temperatures
in order to dehumidify the air. The A/C indicator light
will be lit when the system is operating automatically,
even at near freezing outside temperatures. Press
the A/C button on the fan control to turn off the A/C.
For improved window clearing performance in defog
or defrost modes, the A/C compressor will run
automatically in damp cool conditions.

?(Recirculation):Press this button to keep outside
air from coming in the vehicle. It can be used to
prevent outside air and odors from entering your vehicle
or to help 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.
«ª(Driver’s Temperature Controls):Press these
buttons next to the fan control to manually increase
or decrease the temperature inside your vehicle.
«ª(Passenger’s Temperature Controls):Press
these buttons next to the mode control to manually
increase or decrease the temperature for the front
passenger. If the passenger’s climate control system
is off, pressing one of these buttons will turn it on.
PASS (Passenger’s Climate Control):Press
this button to turn the passenger’s climate control
systems on or off. The temperature selected by the
front passenger will also control the rear system
air temperature unless the rear seat passengers select
their own comfort setting.If the PASS button is pressed to turn the Passenger
temperature setting off, the driver’s temperature
knob will control the temperature for the entire vehicle.

control fan on for automatic operation. After the AUX
button is pressed, the indicator light will come on.
Press the button again to turn the auxiliary fan off.
#(Air Conditioning):Press this button to override
the automatic system and turn the air-conditioning
system on or off. When in AUTO, the air-conditioning
compressor will come on automatically, as necessary.
The air-conditioning system removes moisture from
the air, so you may notice a small amount of water
dripping underneath your vehicle while idling or after
turning off the engine. This is normal.
3-47

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 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 from
your windshield. Use the oor/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.
W(Floor/Defog):Turning the control to this mode
directs approximately half of the air to the oor outlets
and the remaining air is directed to the side window
outlets and to the windshield. 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 oor/defog mode.
0(Defrost):Turning the control to this mode directs
most of the air to the windshield and the side window
outlets. In this mode, the system will automatically turn
off recirculation and run the air-conditioning compressor,
unless the outside temperature is at or below freezing.
Recirculation cannot be selected while in the defrost
mode. Do not drive the vehicle until all the windows
are clear.
For professional vehicles, air will be allowed to ow
through the rear outlets. For quicker defrost, press the
AUX button on the front climate control system so
that the light is not lit.

metric tire sizing system. The letter P as the rst
character in the tire size means a passenger vehicle tire
engineered to standards set by the U. S. Tire and
Rim Association.
(B) Tire Width:The three-digit number indicates the
tire section width in millimeters from sidewall to sidewall.
(C) Aspect Ratio:A two-digit number that indicates
the tire height-to-width measurements. For example, if
the tire size aspect ratio is 60, as shown in item C of the
illustration, it would mean that the tire’s sidewall is
60 percent as high as it is wide.
(D) Construction Code:A letter code is used to
indicate the type of ply construction in the tire. The
letter R means radial ply construction; the letter D means
diagonal or bias ply construction; and the letter B means
belted-bias ply construction.(E) Rim Diameter:Diameter of the wheel in inches.

the load range and speed rating of the tire. The load
index represents the load carry capacity a tire is certied
to carry. The load index can range from 1 to 279. The
speed rating is the maximum speed a tire is certied
to carry a load. Speed ratings range from A to Z.
Tire Terminology and Denitions
Air Pressure:The amount of air inside the tire pressing
outward on each square inch of the tire. Air pressure
is expressed in pounds per square inch (psi) or
kilopascal (kPa).
Accessory Weight:This means the combined weight
of optional accessories. Some examples of optional
accessories are, automatic transmission, power steering,
power brakes, power windows, power seats, and air
conditioning.
