Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle. If your vehicle has
the remote start feature, the climate control system will
function as part of the remote start feature. The
system will return to the last settings the vehicle was at
when it was turned off.
Operation
9
(Fan):Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
The fan must be on to run the air-conditioning
compressor.
To change the air delivery settings, turn the right knob
to select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs half of the air to the
instrument panel outlets, and the remaining air to
the oor outlets. Some air may be directed toward the
side windows.
3-22

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 warms
the coolant that the engine uses to provide heat to
warm the inside of your vehicle. For more information,
seeEngine Coolant Heater on page 2-24.
#(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.
3-24

If your vehicle has the remote start feature, the rear
defogger and heated mirrors 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 and heated mirrors will
turn off.
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
Use the thumbwheels on the air outlets, located on the
center and on the sides of the instrument panel, to
change the horizontal direction of the air ow. Use the
tabs on the outlet vanes to change the vertical direction
of the air ow. Use the tabs on the outlet vanes to
shut off air ow to the outlets.
The two upper outlets in the center of the instrument
panel are dedicated to the rear seats. These outlets
are xed to aim air ow into the rear seats to help
cool the rear occupants in hot weather. Air ow can
be shut off at the upper outlets by turning the vertical
thumbwheel. The louvers are xed, do not attempt
to move them or they may break.
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 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.

The Driver Information Center (DIC) may display a
Low Brake Fluid or Push Park Pedal message. These
messages might help to determine why the brake
system warning light is on. SeeDIC Warnings and
Messages on page 3-55.
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
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. If the light
comes on and the chime sounds 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. 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 3-40earlier in this section.
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 does not come on then, have it xed
so it will be ready to warn you if there is a problem.

CB radio, mobile telephone, or two-way radio, make
sure that it can be added by checking with your
dealer. Also, check federal rules covering mobile
radio and telephone units. If sound equipment can
be added, it is very important to do it properly.
Added sound equipment may interfere with
the operation of your vehicle’s engine, radio, or
other systems, and even damage them. Your
vehicle’s systems may interfere with the operation
of sound equipment that has been added.
Figure out which audio system is in your vehicle, nd
out what your audio system can do, and how to operate
all of its controls.
