?(Recirculation):Press the left side of the button
to turn the recirculation mode on. When recirculation
mode is selected, the air inside the vehicle will be
recirculated through the climate control system and the
vehicle, not from outside your vehicle. This mode is
helpful when you are trying to limit odors from entering
your vehicle and for maximum air conditioning
performance in hot weather. When the button is pressed,
an indicator light above the button will come on to let you
know that it is activated. The recirculation indicator light
will blink three times if you try to use recirculation in a
mode that it can not be used in. Only use this mode when
it is needed for comfort, since window fogging will rapidly
occur if the air conditioning compressor is not engaged.
Pressing this button will cancel the outside air mode.
When you switch to the defog or defrost modes the
system will automatically move from recirculation to
outside air. When you move the mode knob back to
another air delivery mode, the system will move back into
recirculation. When the vehicle or fan is turned off and
back on, the system will default to outside air
automatically. Only use recirculation mode when it is
needed for comfort, since window fogging may occur.
Temperature Control:Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside your vehicle.
When it’s cold outside 0°F (−18°C) or lower, use the
engine coolant heater, if equipped, to provide warmer air
faster to your vehicle. An engine coolant heater warmsthe coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
seeEngine Coolant Heater on page 2-27.
#(Air Conditioning):Press this button to turn the air
conditioning system on or off. When the air conditioning
button is pressed, an indicator light will come on to let you
know that air conditioning is activated.
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, do the following:
1. Select the vent mode.
2. Select the highest fan speed.
3. Select air conditioning.
4. Select the recirculation mode.
5. Select the coolest temperature.
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 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.

Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear):Press this button to turn the rear window
defogger on or off. An indicator light above the
button will come on to let you know that the rear window
defogger is activated.
If driving below 50 mph (80 km/h), the rear window
defogger will turn off about 15 minutes after the button
is pressed. If you need additional warming time,
press the button again.
If your vehicle’s speed is maintained above 50 mph
(80 km/h), the rear window defogger will remain on once
the button is pressed.
If your vehicle has the remote start feature, the rear
defogger will automatically be turned on if it is cold
outside. The indicator light will not be on. When
the vehicle transitions out of remote start mode the rear
defogger will turn off.
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
Rotate the instrument panel outlets and move the
louvers on the outlets to change the direction and
amount of air ow in your vehicle.
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 of your vehicle more
effectively.
When an objectionable odor outside the vehicle is
encountered, use the recirculation mode, with the
temperature knob at a comfortable setting to prevent
the odor from entering the vehicle through the
ventilation system. This can be helpful when driving
through a long tunnel with poor ventilation.
However, extended usage of this mode in cold or
cool weather can cause window 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 doesn’t
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 4-38.
{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 your vehicle has the
anti-lock brake system, the
light will come on when
your engine is started
and may stay on for
several seconds.
That’s normal.
If the light stays on, turn the ignition to OFF. Or, if the
light comes on when you’re 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’re driving, your vehicle
needs service. If the regular brake system warning
light isn’t on, you still have brakes, but you don’t have
anti-lock brakes. If the regular brake system warning
light is also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
Brake System Warning Light on page 3-36.
The anti-lock brake system warning light will come on
brie y when you turn the ignition key to ON. This is
normal. If the light doesn’t come on then, have it xed
so it will be ready to warn you if there is a problem.
