For the automatic system to function, the temperature
must be set between 61°F (15°C) and 89°F (32°C).
1. Adjust the temperature to a comfortable setting.
2. Press the PASS button or the up or down arrows
on the passenger side to turn the passenger
temperature set on and off. When turned on, the
passenger temperature will be the same as the driver
setting. Press the up or down arrow on passenger
side to adjust the passenger temperature setting.
When the passenger temperature set is off, the
passenger display will be off and the driver’s
set temperature will be for the driver and passenger.
In cold weather, the system will start at reduced
fan speeds to avoid blowing cold air into the 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 the 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.4. Press OFF to turn the climate control system off.

h(Recirculation):Press this button to turn
recirculation mode on or off. This mode keeps outside
air from coming into the vehicle. It can be used to prevent
outside air and odors from entering your vehicle or to help
cool the air inside the vehicle more quickly.
Recirculation is not available while in the oor, defrost, or
oor/defog modes. Using recirculation for long periods of
time may cause the air inside your vehicle to become too
dry. Recirculation mode has a 5 minute timer after which
the system allows for some fresh outside air into the
vehicle to maintain interior air quality.
#(Air Conditioning):Press this button to turn the air
conditioning compressor on and off. The indicator light
on the button will come on when the air conditioning is
on. Note that the indicator light will change with each
button press even when conditions prevent operation.
The indicator light on the air conditioning button will come
on every time the vehicle is started. The air conditioning
may be turned off by pressing the air conditioner button.
((Heated Seats):Press this button to turn the driver
or passenger heated seats on and off. SeeHeated
Seats on page 1-4for additional information.
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 oor/defog mode to clear the
windows of fog or moisture and warm the passengers.
Use defrost to remove fog or frost from the windshield
more quickly.
-(Floor/Defog):Press this button to direct the air
between the windshield, oor outlets and side windows.
When you select this mode, the system turns recirculation
off and runs the air conditioning compressor unless the
outside temperature is near or below freezing. Pressing
the recirculation button will have no effect other than
turning on the indicator light while in oor/defog mode.
1(Defrost):Press this button to direct most of the
air to the windshield, with some air directed to the side
windows. In this mode, the system will automatically
turn off the recirculation and run the air conditioning
compressor, unless the outside temperature is near or
below freezing. Pressing the recirculation button will have
no effect other than turning on the indicator light while in
defrost mode.
Do not drive the vehicle until all windows are clear.

Sensors
The solar sensor on the vehicle monitors the solar
heat and the air inside of the vehicle. This information is
used 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.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. The rear
window defogger will only work when the engine
is running.
=(Rear Window Defogger):Press this button to
turn the rear window defogger on and off. Be sure
to clear as much snow from the rear window as possible.
The rear window defogger will turn off approximately
20 minutes after the button is pressed. If turned on again,
the defogger will only run for approximately 20 minutes
before turning off. The defogger can also be turned off by
pressing the button again or by turning off the engine.
Do not drive the vehicle until all the windows are clear.Notice:Do not use a razor blade or sharp object to
clear the inside rear window. Do not adhere anything
to the defogger grid lines in the rear glass. These
actions may damage the rear defogger. Repairs
would not be covered by your warranty.
Outlet Adjustment
Use the thumbwheels located between the center
outlets to open and close the outlets. Move the lever in
the center of each air outlet to adjust the direction of
the airow.
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 the 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 the vehicle more
effectively.
If the vehicle has a passenger compartment air lter
and the airow seems low when the fan is at the
highest setting it may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-30.

If things like suitcases, tools, packages, or anything else
are put inside the vehicle, they will go as fast as the
vehicle goes. If you have to stop or turn quickly,
or if there is a crash, they will keep going.
{CAUTION:
Things you put inside your vehicle can strike
and injure people in a sudden stop or turn, or
in a crash.
Put things in the trunk of your vehicle. In
a trunk, put them as far forward as you
can. Try to spread the weight evenly.
Never stack heavier things, like suitcases,
inside the vehicle so that some of them
are above the tops of the seats.
Do not leave an unsecured child restraint
in your vehicle.
When you carry something inside the
vehicle, secure it whenever you can.
Do not leave a seat folded down unless
you need to.
Towing
Towing Your Vehicle
Consult your dealer or a professional towing service if
you need to have your disabled vehicle towed. See
Roadside Assistance Program on page 7-6.
If you want to tow your vehicle behind another vehicle
for recreational purposes (such as behind a motorhome),
see “Recreational Vehicle Towing” following.
Recreational Vehicle Towing
Recreational vehicle towing means towing your vehicle
behind another vehicle — such as behind a motorhome.
The two most common types of recreational vehicle
towing are known as dinghy towing, towing your vehicle
with all four wheels on the ground, and dolly towing,
towing your vehicle with two wheels on the ground and
two wheels up on a device known as a dolly.
With the proper preparation and equipment, many
vehicles can be towed in these ways. See “Dinghy
Towing” and “Dolly Towing,” following.

Tire Size
The following illustration shows an example of a typical
passenger vehicle tire size.
(A) Passenger (P-Metric) Tire:The United States
version of a 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.
(F) Service Description:These characters represent
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.
Aspect Ratio:The relationship of a tire’s height to
its width.
