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.
When your vehicle is first started, the display will show
the driver’s temperature setting, the fan speed and
the air delivery mode.
When the ENG/MET (English/metric) button on the
Driver Information Center (DIC) is pressed, the display
will show readings in Fahrenheit or Celsius. Use the
ENG/MET button to toggle between them.
Manual Operation
SMODET:Pressing the MODE switch and changing
the mode cancels automatic operation and places the
system in manual mode. Press AUTO to return to
automatic operation.
To change the current mode, select one of the following:
G(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.
8(Floor):This mode directs most of the air to the
floor outlets with some air directed to the outboard
outlets (for the side windows) a little air directed to the
windshield.
The MODE switch can also be used to select the
floor/defog mode. Information on defogging and
defrosting can be found later in this section.
y9z(Fan):Press this switch to increase or
decrease the fan speed. Pressing this switch cancels
automatic operation and places the system in manual
mode. Press AUTO to return to automatic operation.
If the airflow seems low when the fan speed is at
the highest setting, the passenger compartment air filter
may need to be replaced. For more information, see
Passenger Compartment Air Filter on page 3-35
andScheduled Maintenance on page 6-4.

?(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 air-conditioning compressor also
comes on.
TEMP (Driver’s Temperature Knob):Press this knob
to turn the climate control system on or off. Turn this
knob clockwise or counterclockwise to manually
increase or decrease the temperature inside your
vehicle.
TEMP (Passenger’s Temperature Knob):Press this
knob to turn the passengers’ climate control system
controls on or off. Turn this knob to manually increase
or decrease the temperature for the front passenger.
If the passenger’s climate controls are turned off,
the driver’s temperature knob will control the
temperature for the entire vehicle.
A/C (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.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:
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.
6. Open all outlets.
Using these settings together for long periods of time
may cause the air inside 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.
If your vehicle has the memory option, it can be used to
recall your climate control settings. For more information,
seeClimate Controls Personalization on page 3-36.

SensorsThe solar sensor on your vehicle monitors the solar
radiation inside your vehicle, then uses the information
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 middle of the instrument panel, near the windshield
or the system will not work properly.
There is also an outside temperature sensor located
under the front bumper and an inside temperature
sensor located to the left of the ignition switch. These
sensors read the outside and inside air temperature and
help to maintain the selected temperature inside the
vehicle. If you cover these sensors, it could cause
a false reading in the temperature.
3-31

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 floor/defog mode to clear
the windows of fog or moisture and warm the
passengers. Use the defrost mode (FRONT) to remove
fog or frost from the windshield more quickly.
SMODET:Press this switch until floor/defog
appears on the display.
/(Floor/Defog):This mode directs the air equally
between the windshield and the floor 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 floor/defog mode.
1FRONT (Defrost):Pressing FRONT directs most of
the air to the windshield and the side window outlets, with
some air directed to the floor 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.
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
ignition is in ON.
=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 approximately 10
minutes after the button is pressed. If turned on
again, the defogger will only run for approximately five
minutes before turning off. The defogger can also
be turned off by pressing the button again or by turning
off the engine.
The heated outside rearview mirrors will heat to help
clear fog or frost from the surface of the mirror when the
REAR 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.

Outlet Adjustment
Use the levers located in the center of each outlet to
change the direction of the airflow. Use the thumbwheels
to open or close the outlets.
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.
•If the airflow seems low when the fan speed is at
the highest setting, the passenger compartment
air filter may need to be replaced. For more
information, seePassenger Compartment Air Filter
on page 3-35andScheduled Maintenance on
page 6-4.

Rear Climate Control System
Your vehicle has a rear climate-control system that
allows the rear-seat passengers to adjust the direction
of the airflow and the fan speed for the rear seating
area. This system also works with the main
climate-control system in your vehicle.
The control panel for this system is located on the back
of the center console.
OFF:Turn the mode knob located on the rear climate
control panel to this position to turn off the airflow.
If the passenger’s temperature knob located on the main
climate control panel is off, the rear climate control
system will be turned off and the settings selected for
the main climate control panel will also be selected
for the rear seat passengers.For more information on how to use the climate control
system, seeDual Climate Control System on
page 3-28. For more information on the air outlets, see
Outlet Adjustment on page 3-33.
Operation
Mode Knob:Turn the knob to direct the airflow in the
rear-seating area.
To change the current mode, select one of the following:
G(Vent):This mode directs air to the upper outlets,
with some air directed to the floor outlets.
+(Bi-Level):This mode directs half the air to the
upper outlets, and then directs the remaining air to the
floor outlets.
8(Floor):This mode directs the air to the floor
outlets.
9(Fan):Slide this lever to the left or right, between
LO and HI, to decrease or increase the fan speed.

Passenger Compartment Air Filter
Passenger compartment air, both outside air and
recirculated air, is routed through a passenger
compartment filter. The filter removes certain
contaminants from the air, including pollen and dust
particles.The filter is located inside the air control module, with
an access panel under the instrument panel near
the accelerator pedal.
Reductions in airflow, which may occur more quickly in
dusty areas, indicate that the filter needs to be
replaced. The filter also should be replaced as part of
routine scheduled maintenance. SeeScheduled
Maintenance on page 6-4for replacement intervals. See
your dealer for assistance when changing the filter.
Your vehicle will not be damaged if you choose not to
replace the filter once the old one is removed.

Warning Lights, Gages and
Indicators
Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages that may
be on your vehicle. The pictures will help you locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or is a
problem with one of your vehicle’s functions. As you will
see in the details on the next few pages, some
warning lights come on briefly when you start the
engine just to let you know they are working. If you are
familiar with this section, you should not be alarmed
when this happens.Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there is a problem with your vehicle.
When one of the warning lights comes on and stays on
when you are driving, or when one of the gages
shows there may be a problem, check the section that
tells you what to do about it. Follow this manual’s
advice. Waiting to do repairs can be costly – and even
dangerous. So please get to know your warning
lights and gages. They are a big help.
Your vehicle also has a Driver Information Center (DIC)
that works along with the warning lights and gages.
SeeDriver Information Center (DIC) on page 3-52for
more information.

Instrument Panel Cluster
The instrument panel cluster is designed to let you know at a glance how your vehicle is running. You will know how
fast you are going, how much fuel you are using and many of the other things you will need to know to drive safely
and economically.
