For quick cool down on hot days, do the following:
1. Select the vent mode.
2. Select the outside air.
3. Select A/C.
4. Select the coolest temperature for both zones.
5. Select the highest fan speeds.
6. Once the vehicle’s interior temperature is below the
outside temperature, select recirculation mode for
enhanced cooling.
Using these settings together for long periods of time
may cause the air inside of your vehicle to become
too dry. To prevent this from happening, after the
air inside of 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.Defogging and Defrosting
Fog on the inside of the 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 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.
Turn the right knob clockwise to select the defog or
defrost mode. Do not drive the vehicle until all the
windows are clear.
-(Defog):This mode directs air equally to the
windshield and the oor outlets. When you select this
mode, the system turns off recirculation and runs the air
conditioning compressor unless the outside temperature
is below 40°F (4°C). The recirculation mode cannot
be selected while in the defog mode.
0(Defrost):This mode directs a portion of the air
to the windshield and side window vents and some
to the oor vents. In this mode, the system will
automatically force outside air into your vehicle.
The recirculation mode cannot be selected while in
the defog mode. The air conditioning compressor will
run automatically in this setting, unless the outside
temperature is below 40°F (4°C).

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<:The rear window defogger will turn off automatically
after it has been activated. The duration the rear window
defogger is on will be longer if the vehicle is being driven.
The defogger can also be turned off by pressing the
button again or by turning off the engine.
If your vehicle has heated outside rearview mirrors, the
mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog button
is pressed.
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.
Outlet Adjustment
Use the thumbwheel located below or to the side of the
outlet, to change the direction of the air ow.
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 de ectors may
adversely affect the performance of the system.
Keep the path under the front seats clear of objects
to help circulate the air inside your vehicle more
effectively.
If the air ow seems low when the fan is at the
highest setting, the passenger compartment
air lter, if equipped, may need to replaced. For
more information, seePassenger Compartment Air
Filter on page 3-23andScheduled Maintenance
on page 6-4.
If fogging reoccurs while in vent or bi-level modes
with mild temperature throughout the vehicle, turn
on the air conditioner to reduce windshield fogging.

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 4-34.
{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
Your vehicle may have an
Anti-Lock Brake System
(ABS) warning light.
It should come on for a few seconds when you turn the
ignition key to RUN.
If the ABS warning light stays on longer than normal
after you have started your engine, turn the ignition off
or, if the light comes on and stays 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, the ABS needs service and you do not have
anti-lock brakes.
The ABS warning light should come on brie y when you
turn the ignition key 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.
