9(Fan Control):Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
The fan must be on to run the air conditioning
compressor.
Temperature Control:Turn the knob clockwise or
counterclockwise to increase or decrease the
temperature inside the vehicle.
When it is cold outside−18°C (0°F) or lower, use the
engine coolant heater, if the vehicle has one, to quickly
provide warmer air. An engine coolant heater warms
coolant that the engine uses to warm the inside of the
vehicle. For more information, seeEngine Coolant
Heater on page 3-23.
Air Delivery Mode Control:Turn the knob clockwise
or counterclockwise to change the air delivery settings.
Select from the following modes:
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level):Air is divided between the air to the
instrument panel and floor outlets. Some air may
be directed toward the side windows.
6(Floor):Air is directed to the floor outlets with
some air directed to the side window outlets and
windshield.
-(Defog):This mode clears the windows of fog or
moisture. Air is directed to the windshield and floor
outlets, with some air directed to the side windows.
When this mode is selected, the system automatically
turns off recirculation and tuns the air conditioning
compressor unless the outside temperature is at
or below freezing. The air conditioning compressor
operates although the indicator light is not on. The air
conditioning indicator light turns off when defog is
selected. If the air conditioning button is pressed while
in defog mode, the indicator light turns on. If the
button is pressed again, the light turns off. The
recirculation mode cannot be selected while in the defog
mode. Do not drive the vehicle until all the windows
are clear.
1(Defrost):This mode clears the windshield of fog
or frost more quickly. Air is directed to the windshield,
with some air directed to the floor vents. In this
mode, the system automatically forces outside air into
the vehicle. The air conditioning compressor runs unless
the outside temperature is at or below freezing. The
air conditioning compressor operates although the
indicator light is not on. The air conditioning indicator
light turns off when defrost is selected. If the air
conditioning button is pressed while in defrost mode, the
indicator light turns on. If the button is pressed again,
the light turns off. Recirculation cannot be selected while
in the defrost mode.

Also be careful not to cover the sensor grille on the
lower right side of the climate control faceplate.
This senses the inside vehicle temperature needed
for proper regulation.
To avoid blowing cold air at start-up in cold weather,
the system delays turning on the fan until warm
air is available. The length of delay depends on the
engine coolant temperature. Turning the fan
knob overrides this delay and change the fan to a
selected speed.
If the vehicle has the remote start feature, the climate
control display initially shows “RS” in place of the
temperature to indicate the remote start has been
activated. The remote start system turns on using the
last temperature selected before the vehicle was
last turned off.
For best performance, turn the fan and mode knobs to
the AUTO position. The fan speed and air delivery
modes will change to achieve the best comfort.
If the outside air temperature is below 7°C (45°F) and
the air delivery mode knob is set to AUTO, the automatic
climate control system starts in the defrost mode to
clear the window.
The automatic climate control changes back to manual
operation by turning the vehicle on with the key.Manual Operation
The air delivery mode or fan speed can be manually
adjusted.
9(Off):Turns off the entire climate control system.
Outside air still enters the vehicle, and is directed to the
floor. This direction can be changed by adjusting the
air delivery mode position.
9(Fan Control):Turn the knob clockwise or
counterclockwise to increase or decrease the fan speed.
xwTemperature Control:Press the up and down
arrows to increase or decrease the temperature
inside the vehicle.
Air Delivery Mode Control:Turn the knob clockwise
or counterclockwise to change the air delivery settings.
Select from the following modes:
H(Vent):Air is directed to the instrument panel
outlets.
)(Bi-Level):Air is divided between the instrument
panel and floor outlets.

Outlet Adjustment
Rotate the instrument panel outlets and move the
louvers on the outlets to change the direction and
amount of airflow inside the vehicle.
Operation Tips
•Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that can
block the flow of air into the vehicle.
•Use of non-GM approved hood deflectors can
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.
•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.
Warning Lights, Gages, and
Indicators
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
the warning lights and gages could prevent injury.
Warning lights come on when there might be or there is
a problem with one of the vehicle’s functions. Some
warning lights come on briefly when the engine is started
to indicate they are working.
Gages can indicate when there might be or there is a
problem with one of the vehicle’s functions. Often gages
and warning lights work together to indicate a problem
with the vehicle.
When one of the warning lights comes on and stays on
while driving, or when one of the gages shows there
could be a problem, check the section that explains what
to do. Follow this manual’s advice. Waiting to do
repairs can be costly and even dangerous.

When the ignition is on, the brake system warning light
also comes on when the parking brake is set. The
light will stay on if the parking brake does not fully
release. If it stays on after the parking brake is fully
released, it means there is a brake problem.
{WARNING:
The brake system might not be working properly if
the brake system warning light is on. Driving with
the brake system warning light on can lead to a
crash. If the light is still on after the vehicle has
been pulled off the road and carefully stopped,
have the vehicle towed for service.
If the light comes on while driving, pull off the road and
stop carefully. The pedal can be harder to push, or
the pedal could go closer to the floor. It could take
longer to stop. Try turning off and restarting the vehicle
one or two times, if the light is still on, have the
vehicle towed for service. SeeTowing Your Vehicle on
page 5-23.
Antilock Brake System (ABS)
Warning Light
The Antilock Brake
System (ABS) light comes
on briefly when the
engine is started.
If it does not, have the vehicle serviced by your
dealer/retailer. If the system is working normally the
indicator light then goes off.
If the ABS light stays on, turn the ignition off. If the light
comes on while driving, stop as soon as it is safely
possible and turn the ignition off. Then start the engine
again to reset the system. If the ABS light stays on,
or comes on again while driving, the vehicle needs
service. If the regular brake system warning light is not
on, the vehicle still has brakes, but not antilock
brakes. If the regular brake system warning light is also
on, the vehicle does not have antilock brakes and
there is a problem with the regular brakes. SeeBrake
System Warning Light on page 4-30.
For vehicles with a Driver Information Center (DIC), see
DIC Warnings and Messages on page 4-42for all
brake related DIC messages.
