Climate Controls
Dual Climate Control System
With this system you can control the heating,
cooling, and ventilation for the 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.
Dual Climate Control System
210

After the 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.
h(AUTO RECIRCULATION):If the AUTO
position is selected on either the fan or mode
control, the system will automatically control the air
inlet to supply fresh outside air or recirculate the
interior air to cool the car faster. The indicator light
on the recirculation button will light whenever the
system switches to recirculation. You may force
outside air by pressing the recirculation button
when the light is lit. For vehicles without rear climate
controls, press the outside air button to force
outside air. The next time AUTO fan or mode is
selected, the air inlet will reset back to AUTO
operation.
Manual Operation
9(Fan):Turn the left control either to the left or
right to adjust the fan speed. Turning this control
completely counterclockwise will turn on the
automatic fan operation. Turning this control to the
“O” position will turn the climate control system off.
If the airow seems low when the fan speed is at
the highest setting, the passenger compartment air
lter may need to be replaced. SeePassenger
Compartment Air Filter on page 220.
9(Off):Turn the left control to this position to
turn the entire climate control system off.
To change the current mode, select one of the
following positions using the right control:
AUTO:Turn the control to this position to turn on
the automatic delivery mode operation.
F(Vent):Turn the control to this mode to direct
air to the instrument panel outlets.
*(Bi-Level):Turn the control to this mode to
direct approximately half of the air to the instrument
panel outlets and most of the remaining air to the
oor outlets. In automatic operation, cooler air is
directed to the upper outlets and warmer air to the
oor outlets.
212

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog or frost from the rear window.
<(Rear Defogger):Press the center of the right
control 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 20 minutes after the button is
pressed if your vehicle is moving at slower vehicle
speeds. At higher vehicle speeds, the rear defogger
may stay on continuously. Each additional press
will run the defogger for approximately 10 minutes.
The heated outside rearview mirrors will heat to
help clear fog or frost from the surface of the mirror
when the rear window defogger is on.
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
For the front outlets, use the thumbwheel located
below each outlet to change the direction of the
airow. Use the thumbwheel located next to the
outlets to shut the airow or to open the outlets
and re-direct the air.
For the rear outlets, slide the lever left or right
and up or down to change 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 your 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 your vehicle more effectively.

When the ignition is on, the brake system warning
light will also come on when you set your parking
brake. The light will stay on if your parking brake
does not release fully. If it stays on after your
parking brake is fully released, it means you
have a brake problem.
If the light comes on while you are driving, pull
off the road and stop carefully. You may notice that
the pedal is harder to push, or the pedal may go
closer to the oor. It may take longer to stop.
If the light is still on, have the vehicle towed for
service. SeeTowing Your Vehicle on page 340.
{CAUTION:
Your brake system may not be working
properly if the brake system warning
light is on. Driving with the brake system
warning light on can lead to an accident.
If the light is still on after you have pulled
off the road and stopped carefully, have
the vehicle towed for service.
Anti-Lock Brake System Warning
Light
With the anti-lock brake
system, the light will
come on when your
engine is started
and may stay on for
several seconds.
That is normal.
If the ABS warning light comes on and stays on,
there may be a problem with the antilock portion
of the brake system. If the red BRAKE light is
not on, you still have brakes, but you do not have
antilock brakes. SeeBrake System Warning
Light on page 229.
If the light stays on, turn the ignition to OFF or
ACCESSORY. If the light comes on when you are
driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset
the system. If the light still stays on, or comes on
again while you are driving, your vehicle needs
service. If the regular brake system warning light
is not on, you still have brakes, but you do not
have anti-lock brakes.
230

If the regular brake system warning light is also
on, you do not have anti-lock brakes and there is
a problem with your regular brakes. SeeBrake
System Warning Light on page 229.
The anti-lock brake system warning light should
come on briey when you turn the ignition key to
RUN. If the light does not come on then, have it
xed so it will be ready to warn you if there is a
problem.
Low Tire Pressure Warning Light
This light will come on
briey when you turn
the ignition to RUN.This light will also come on when one or more of
your tires are signicantly underinated.
A CHECK TIRE PRESSURE DIC message will
accompany the light, seeDIC Warnings and
Messages on page 246
Stop and check your tires as soon as it is safe
to do so. If underinated, inate to the proper
pressure. SeeTires on page 402for more
information.
This light will ash for approximately 60 seconds
and then turn on solid if a problem is detected with
the Tire Pressure Monitor system.
SeeTire Pressure Monitor System on page 414
for more information.
