An indicator light to the right of the button will
come on to show that the recirculation button has
been pressed. The instrument panel brightness
control may have to be adjusted to the highest
setting to see the indicator.
The recirculation mode has a timer. After
ve minutes, the system’s air inlet door will move
slightly to allow for ten percent fresh outside
air to maintain interior air quality. The only way to
reset the system to full recirculation is to restart
the ve minute timer by selecting vent/outside air
and recirculation again.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Be
sure to clear as much snow from the rear window
as possible.

Dual Automatic Climate Control
System
With this system you can control the heating,
cooling, and ventilation for your vehicle.
Automatic Operation
AUTO (Automatic):Turn both the fan and mode
knob to AUTO for automatic control of the inside
temperature, the air delivery mode and the fan
speed. You may notice a delay of two to
three minutes before the fan comes on when the
automatic operation is used in cold weather.For the automatic system to function, the
temperature must be set between 60°F (15°C) and
90°F (32°C).
1. Adjust the temperature to a comfortable
setting.
2. Press the PASS button to turn the passenger
climate control system on and off. When the
passenger system is off, the driver’s
temperature setting is also used for the
passenger and the passenger display is off.
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 for the air to
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.
162

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.
Manual Operation
xw
(Temperature):To manually adjust the
temperature inside the vehicle, press the up arrow
on the temperature control to raise the temperature

When one temperature is displayed, the driver
temperature is set. When both temperatures are
displayed, the temperature for both the driver
and passenger are set. Pressing PASS will turn
the passenger temperature setting on and
off. If only the driver temperature is set, the driver
temperature is used for the passenger and the
passenger display is off.
9(Fan):Turn the fan knob clockwise to increase
the fan speed and counterclockwise to decrease
the fan speed. Turning the fan knob cancels
the automatic fan operation and places the systemin manual. Turn the knob to AUTO to return to
automatic fan operation. If the airow seems low
when the fan is at the highest setting, the
passenger compartment air lter, if equipped, may
need to be replaced. SeePassenger Compartment
Air Filter on page 166for additional information.
9(Off):Turning the fan knob off will turn
the controller completely off.
Mode:This control has several settings to control
the direction of airow.
To change the current mode, select one of the
following:
AUTO:This mode is automatically set depending
on the temperature in the vehicle and solar
sensor information.
H(Vent):This mode directs air to the
instrument panel outlets.
%(Bi-Level):This mode directs airow to the
instrument panel outlets and to the oor outlets.
A small amount of air is also directed to the
windshield and the side window outlets.
163

6(Floor):This mode directs most of the air to
the oor outlets with some air directed to the
side window outlets, and a little air directed to the
windshield.
#(Air Conditioning):Press this button to turn
the air conditioning compressor on or off. The
indicator light on the button will come on when the
air conditioning is on.
?(Recirculation):Press this button to turn
the recirculation mode on or off. This mode keeps
outside air from coming in the vehicle. It can be
used to help reduce the outside air and odors that
may enter the vehicle or help to cool the air
inside the vehicle quicker.
Recirculation is not available in defrost or
oor/defog mode. Pressing the recirculation button
will turn on the indicator light.
Using recirculation 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.
z(Heated Seats):Press this button to turn the
heated seats on and off. The button on the left
controls the driver’s seat and the button on
the right controls the passenger’s seat. See
Heated Seats on page 10for additional
information.
Sensors
The solar sensor on your vehicle monitors the
solar radiation and the air inside of 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 center of the instrument panel, near the
windshield, or the system will not work properly.
164

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 the defrost mode to remove fog
or frost from the windshield more quickly.
-(Floor/Defog):This mode directs the air
between the windshield, oor outlets and side
windows. When you select this mode, the system
turns off recirculation and runs the air-conditioning
compressor unless the outside temperature is near
or below freezing. Pressing the recirculation button,
while in this mode, will have no effect other than
turning on the indicator light.
1(Defrost):This mode directs 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, while in this mode, will have no
affect other than turning on the indicator light.
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 about
20 minutes after the button is pressed. If turned
on again, the defogger will only run for about
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 anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the repairs
would not be covered by your warranty. Do not
attach a temporary vehicle license, tape, a decal
or anything similar to the defogger grid.
165

Outlet Adjustment
Turn the air outlets, located in the middle and at
each outboard side of the instrument panel,
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 airow seems low when the fan is at the
highest setting, the passenger compartment
air lter may need to be replaced. See
“Passenger Compartment Air Filter” following,
for more information.
Passenger Compartment Air Filter
The passenger compartment air lter is located
near the passenger’s side windshield wiper
arm, under the inlet grille.
The lter traps most of the pollen from entering
the climate control system. Similar to the engine’s
air lter, it may need to be changed periodically
to insure system performance. SeeScheduled
Maintenance on page 473for more information.
To change the passenger compartment air
lter, do the following:
1. Turn the ignition to ACC and the windshield
wipers on.
2. Turn the ignition to OFF when the windshield
wipers are in the upright position.
3. Raise the hood.
4. Disconnect the windshield washer pump hose
from the fender rail and the air inlet grille.
5. Remove the hood weather-strip from the
passenger’s side of the vehicle, peeling it
back halfway.
166

6. Remove the two air inlet grille retainers using
a at tool to rst pry up on the center post
and then the remainder of the fastener can be
pulled out.
7. Remove the air inlet grille by sliding it down to
disengage the two tabs that hold it to the
bottom of the windshield glass. Place the grille
on the windshield while you remove the
lter. Do not try to remove the grille from the
vehicle because it is still attached on the
right side of the vehicle by a fastener.8. Remove the water deector.
9. Remove the passenger compartment air lter
by pulling on the tab.
10. Install a new passenger compartment air lter.
Make sure it slides under the compartment
retainers. Be sure the long rubber water
deector above the lter stays in place.
11. Reverse steps 1 through 8.

Warning Lights, Gages, and
Indicators
This part describes the warning lights and gages
that may be on the vehicle. The pictures help
to 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 the 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 the vehicle’s functions. As
the details show on the next few pages, some
warning lights come on briey when the engine is
started just to indicate 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 the vehicle’s functions. Often
gages and warning lights work together to
indicate when there is a problem with the vehicle.
When one of the warning lights comes on and
stays on while the vehicle is being driven, 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 the vehicle’s warning lights
and gages. They can be a big help.
The vehicle also has a Driver Information
Center (DIC) that works along with the warning
lights and gages. SeeDriver Information
Center (DIC) on page 186for more information.
