VENT (Ventilation):This mode brings in outside air
and directs it through the instrument panel outlets.
BI-LEV (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 oor outlets.
Some air may be directed toward the windshield.
HTR (Heater):This mode directs most of the air to the
oor outlets, with some air directed to the outboard
outlets, for the side windows, and some air directed to
the windshield.
BLEND:This mode directs half of the air to go to the
oor outlets and half to the defroster and side window
outlets. The air-conditioning compressor will run
automatically in this setting unless the outside
temperature is below 40°F (4°C).
The right knob can also be used for the defrost mode.
Information on defrosting and defogging can be
found later in this section.
9FAN:The left knob controls the fan speed.
OFF:Turn the knob all the way counterclockwise to
turn off the fan.
LO (Low Fan Speed):This setting creates the lowest
fan speed.HI (High Fan Speed):This setting creates the highest
fan speed.
DRIVER (Driver’s Side Temperature):The lever on
the left adjusts the air temperature for the driver’s
side outlets. Slide the lever up to raise the temperature
and down to lower the temperature.
PASSENGER (Passenger’s Side Temperature):The
lever on the right adjusts the air temperature for the
passenger’s side outlets. Slide the lever up to raise the

"(Air Conditioning):Press this button to turn the
air-conditioning on and off. An indicator light above the
button will come on when the air conditioning is on.
During daylight hours the interior lighting control might
need adjustment to the highest setting in order for the
indicator light to be seen. The system will cool and
dehumidify the air inside the vehicle when the A/C
indicator light is on.
On very hot days, open the windows long enough to let
hot, inside air escape. This reduces the time for the
vehicle to cool down.
For a quick cool-down on a very hot day, use MAX with
the temperature levers all the way in the blue area. If this
setting is used for long periods of time, the air in the
vehicle may become too dry.
For normal cooling on hot days, use VENT with the
temperature levers in the blue area. The system will bring
in outside air and cool it.

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 3-25andScheduled Maintenance on
page 6-4.
Passenger Compartment Air Filter
The passenger compartment air lter is located in
the engine compartment below the inlet grille, near the
passenger’s side of the windshield wiper arm.
The lter traps most of the pollen from the air entering
the air conditioning module. Like the engine’s air
cleaner/lter, it may need to be changed periodically.
For information on how often to change the passenger
compartment air lter, seeScheduled Maintenance
on page 6-4.To change the passenger compartment air lter, use the
following steps:
1. Put the ignition in ACCESSORY and turn 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 air inlet grille.
5. Remove the hood weather-strip from the
passenger’s side of the vehicle and peel it back to
the center of the hood.
6. Remove the three air inlet grille retainers.
7. Remove the air inlet grille.

When the ignition is on, the brake system warning light
will also come on when the parking brake is set.
The light will stay on if the parking brake does not
release fully. If it stays on after the parking brake is fully
released, it means there is a brake problem.
If the light comes on while the vehicle is being driven,
pull off the road and stop carefully. The pedal may
be harder to push. or it 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 4-31.
{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
If the vehicle has anti-lock brakes, this warning light will
come on for a few seconds when the ignition key is
turned to RUN. If the anti-lock brake system warning light
stays on longer than normal after the engine has been
started, turn the ignition off. Or, if the light comes on and
stays on while the vehicle is being driven, 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 driving, the anti-lock brake system
needs service. If the light is on and the regular brake
system warning light is not on, the vehicle still has brakes,
but it does not have anti-lock brakes.
The anti-lock brake system warning light will come on
briey when the ignition key is turned to RUN. This
is normal. If the light does not come on then, have it
xed so it will be ready to warn you if there is a problem.United States

Theft-Deterrent Feature
THEFTLOCK®is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is removed and the
radio is placed in a different vehicle. This feature
requires no user input to be activated. It is automatically
armed when it is put into the vehicle for the rst time.
When the ignition is turned off, the blinking red light
indicates that THEFTLOCK
®is armed.
If THEFTLOCK
®is activated, your radio will not operate
if stolen. The radio will display LOCKED and a red
LED indicator light will come on above the key symbol
to indicate a locked condition. If this occurs, the radio will
need to be returned to the dealer.

Anti-lock Brake System (ABS)
Your vehicle may have anti-lock brakes. ABS is an
advanced electronic braking system that will help
prevent a braking skid.
If your vehicle has anti-lock brakes, this warning light on
the instrument panel will come on briey when you
start your vehicle.
When you start your engine, or when you begin to drive
away, your anti-lock brake system will check itself.
You may hear a momentary motor or clicking noise while
this test is going on, and you may even notice that
your brake pedal moves or pulses a little. This is normal.Let us say the road is wet and you are driving safely.
Suddenly, an animal jumps out in front of you. You slam
on the brakes and continue braking. Here is what
happens with ABS:
A computer senses that wheels are slowing down. If
one of the wheels is about to stop rolling, the computer
will separately work the brakes at each wheel. United States
Canada
4-7

The anti-lock system can change the brake pressure
faster than any driver could. The computer is
programmed to make the most of available tire and road
conditions. This can help you steer around the obstacle
while braking hard.
As you brake, your computer keeps receiving updates
on wheel speed and controls braking pressure
accordingly.Remember: Anti-lock does not change the time you
need to get your foot up to the brake pedal or always
decrease stopping distance. If you get too close to
the vehicle in front of you, you will not have time to apply
your brakes if that vehicle suddenly slows or stops.
Always leave enough room up ahead to stop, even
though you have anti-lock brakes.
Using Anti-Lock
Do not pump the brakes. Just hold the brake pedal
down rmly and let anti-lock work for you. You may feel
a slight brake pedal pulsation or notice some noise,
but this is normal.
Braking in Emergencies
At some time, nearly every driver gets into a situation
that requires hard braking.
If you have anti-lock, you can steer and brake at the
same time. However, if you do not have anti-lock, your
rst reaction — to hit the brake pedal hard and hold
it down — may be the wrong thing to do. Your wheels
can stop rolling. Once they do, the vehicle can not
respond to your steering. Momentum will carry it
in whatever direction it was headed when the wheels
stopped rolling. That could be off the road, into the very
thing you were trying to avoid, or into traffic.
