2008 GMC ACADIA lock

Airow Mode Control:Turn the right knob clockwise
or counterclockwise to direct the airow inside of
the vehicle.
To change the current mode, select one of the following:
H(Vent):This mode directs air to the instrument
panel outlets.
)(Bi-Level):This mode directs about half of the
air to the instrument panel outlets and half to the oor
outlets. A little air is directed towards the windshield
and side window outlets. Cooler air is directed to
the upper outlets and warmer air to the oor outlets.
6(Floor):This mode directs most of the air to
the oor outlets, with some of the air directed to the
windshield, side window outlets, and second row
oor outlets. In this mode, the system automatically
selects outside air. Recirculation cannot be selected
when in Floor Mode.
The right knob can also be used to select defog or
defrost mode. For more information, see “Defogging
and Defrosting” later in this section.
By positioning the right knob between two modes,
a combination of those two modes is selected.
@(Recirculation):Press this button to turn the
recirculation mode on or off. The indicator light on
the button turns on when this mode is selected.This mode keeps outside air from entering the vehicle.
It can be used to reduce the outside air and odors
entering the vehicle. Recirculation may also help cool the
air inside the vehicle more quickly once the temperature
inside the vehicle is less than the outside temperature.
The recirculation mode can be turned off in vent
and bi-level modes by pressing the button again.
Recirculation mode automatically turns off when the
engine is turned off and must be re-selected when the
engine is turned on again.
The recirculation mode cannot be used with oor, defrost,
or defogging modes. If you try to select recirculation in
one of those modes, the indicator ashes three times
and turns off. The air conditioning compressor also
comes on when this mode is activated unless the
outside air temperature is less than 40°F (4°C). While
in recirculation mode the windows may fog when the
weather is cold and damp. To clear the fog, select either
the defog or defrost mode and increase the fan speed.
#(Air Conditioning):Press this button on the left
knob to turn the air conditioning system on or off.
When A/C is pressed, an indicator light comes on to
show that the air conditioning has been activated. The air
conditioning compressor does not operate when outside
temperatures fall below 40°F (4°C). The indicator light
ashes three times and turns off when outside conditions
affect air conditioning operation. This is normal.

For quicker cool down on hot days, do the following:
1. Open the windows to let hot air escape.
2. Select the vent mode.
3. Select the air conditioner.
4. Select the coolest temperature.
5. Select the highest fan speed.
6. Close the windows after the hot air has escaped.
7. Once the vehicle’s interior temperature is below
the outside temperature, select recirculation
mode for better cooling.
This helps to reduce the time it takes for the vehicle
to cool down. It also helps the system to operate
more efficiently.
Using recirculation for long periods of time may
cause the air inside of the vehicle to become too dry.
To prevent this from happening, after the inside of
the vehicle has cooled, turn the recirculation mode off.
The air conditioning system removes moisture from
the air, so you might notice a small amount of water
dripping underneath the front center and right rear
of the 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 the windshield. Turn the right knob
clockwise to select the defog or defrost mode.
-(Defog):The defog mode is used to clear the
windows of fog or moisture and warm the passengers.
This mode directs air to the windshield, oor outlets,
and side window vents. When you select this mode,
the system turns off recirculation and runs the air
conditioning compressor unless the outside temperature
is less than 40°F (4°C). The recirculation mode
cannot be selected while in the defog mode. Do not
drive the vehicle until all the windows are clear.
0(Defrost):The defrost mode is used to remove fog
or frost from the windshield more quickly. This mode
directs most 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 defrost mode. The air conditioning compressor
will run automatically in this setting, unless the outside
temperature is less than 40°F (4°C). Do not drive
the vehicle until all the windows are clear.

Outlet Adjustment
Use the slider switch in the center of the outlet,
to change the direction of the air ow. Use the
thumbwheel near the outlet to control the amount
of air ow or to shut off the airow completely.
Keep all outlets open whenever possible for best
system performance.
Operation Tips
Clear away any ice, snow, or leaves from the
air inlets at the base of the windshield that can
block the ow of air into the vehicle.
Use of non-GM approved hood deectors can
adversely affect the performance of the system.
Keep the path under all seats clear of objects
to help circulate the air inside the vehicle more
effectively.
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.
Rear Air Conditioning and
Heating System
If your vehicle has this system, the rear controls are
three knobs located on the rear of the center console.
The system can be controlled from the front controls
as well as the rear controls.
To turn the system on, press the AUX button on the
front climate control system, an indicator will be
lit. Pressing the AUX button the rst time will turn the
rear system on in a mimic mode. In this mode, the
airow in the rear will be approximately the same
direction, temperature, and fan speed as the front.
Pressing the AUX button again will turn the rear system
and the indicator off.
If the rear controls are adjusted, the system turns
on in a rear independent mode. Airow in the rear
will then be directed according to the settings of the
rear controls. The rear system can be turned off
by pressing the AUX button on the front climate control
system and the indicator will turn off. The system
can be turned back on, by adjusting any of the rear
air conditioning control knobs.

the direction of the air ow.
H(Vent):This setting directs the air through the
headliner outlets.
)(Bi-Level):This setting directs the air through the
rear oor outlets under the third row seat, as well as
the headliner outlets. The ow can be divided between
headliner and oor outlets depending upon where
the knob is placed between the settings.
6(Floor):This setting directs the air through the
oor outlets. The rear system oor outlets are located
under the third row seats.
