air conditioning GMC ACADIA 2007 Owner's Manual

4. Snap the front and the back of the transmitter
together.
5. Test the operation of the transmitter with the
vehicle.
Remote Vehicle Start
Your vehicle may have a remote starting feature.
This feature allows you to start the engine
from outside of the vehicle. It may also start up
the vehicle’s heating or air conditioning systems
and rear window defogger. Normal operation of the
system will return after the key is turned to the
ON position.
If your vehicle has an automatic climate control
system, during remote start, the climate control
system will default to a heating mode during colder
outside temperatures and a cooling mode during
warmer outside temperatures. If your vehicle
does not have an automatic climate control
system, during remote start, the climate control
system will turn on at the setting the vehicle was
set to when the vehicle was last turned off.During a remote start, if your vehicle has an
automatic climate control system and heated
seats, the heated seats will turn on during colder
outside temperatures and will shut off when
the key is turned to RUN. If your vehicle does not
have an automatic climate control system,
during remote start, you will need to manually turn
the heated seats on and off. See Heated Seats
for additional information
Laws in some communities may restrict the use of
remote starters. For example, some laws may
require a person using the remote start to have the
vehicle in view when doing so. Check local
regulations for any requirements on remote starting
of vehicles.
The RKE transmitter with the remote start button,
provides an increased range of operation. However,
the range may be less while the vehicle is running.
As a result, you may need to be closer to your
vehicle to turn it off, than you were to turn it on.
There are other conditions which can affect the
performance of the transmitter, seeRemote
Keyless Entry (RKE) System on page 98for
additional information.

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 of center
and right rear of the vehicle while idling or
after turning off the engine. This is normal.
201

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.
AUX (Auxiliary):Press this button to turn the
rear heating and air conditioning on. SeeRear Air
Conditioning and Heating System on page 211
orRear Air Conditioning and Heating System and
Electronic Climate Controls on page 212.
202

When AUTO is selected, the air conditioning
operation and air inlet are automatically
controlled. The air conditioning compressor
runs when the outside temperature is
over about 40°F (4°C). The air inlet is normally
set to outside air. If it is hot outside, the air
inlet can automatically switch to recirculate
inside air to help quickly cool down your
vehicle. The light comes on the recirculation
button while in recirculation.
2. Set the driver’s and passenger’s temperature.
To nd your comfort setting, start with a
73°F (23°C) temperature setting and allow
about 20 minutes for the system to regulate.
Use the driver’s or passenger’s temperature
buttons to adjust the temperature setting
as necessary. If you choose the temperature
setting of 60°F (15°C), the system remains
at the maximum cooling setting. If you choose
the temperature setting of 90°F (32°C), the
system remains at the maximum heat setting.
Choosing either maximum setting will not
cause the vehicle to heat or cool any faster.Do not cover the solar sensor located on the
top of the instrument panel near the windshield.
This sensor regulates air temperature based
on sun load and also turns on your vehicle’s
headlamps. For more information on the solar
sensor, see “Sensors” later in this section.
To avoid blowing cold air 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. Press the fan switch
to override this delay and change the fan to a
selected speed.
O(On/Off):Press this button to turn off the
climate control system. Outside air still enters
the vehicle, and is directed to the oor. This
direction can be changed by pressing the mode
button. Recirculation can only be selected in
vent or bi-level mode. The temperature can also
be adjusted using either temperature button.
If you adjust the air delivery mode or temperature
settings with the system off, the display comes
on briey to show the settings and then turns off.
Press the on/off button or the up down arrows
on the fan switch, the defrost button, AUTO button,
or the air conditioning button to turn the system
on when it is off.
205

This mode keeps outside air from entering the
vehicle. It can be used to reduce outside air and
prevent odors from entering your vehicle.
Recirculation can also help cool the air inside your
vehicle more quickly once the temperature inside
the vehicle is less than the outside temperature.
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. 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.
Press the button again to turn off the recirculation
mode. It automatically turns off when the engine is
turned off and must be re-selected when the engine
is turned on again.
Air Conditioning
#
(Air Conditioning):Press this button to turn
the air conditioning (A/C) compressor on and off.
When air conditioning is selected, an indicator light
comes on to let you know that the air conditioning
has been activated.The air conditioning compressor does not work
when outside temperatures fall below 40°F (4°C).
Pressing this button when the outside temperature
is too cool makes the air conditioning indicator ash
three times and turn off to let you know the air
conditioning mode is not available. If the air
conditioning is on and the outside temperature
drops below a temperature which is too cool for air
conditioning to be effective, the air conditioning light
turns off to show that the air conditioning mode has
been canceled.
On hot days, open the windows long enough to let
hot inside air escape. This helps to reduce the
time it takes for your vehicle to cool down. It also
helps the system to operate more efficiently.
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.
207

The climate control system uses the information
from these sensors to maintain your comfort
setting by adjusting the outlet temperature, fan
speed, and the air delivery mode. The system may
also supply cooler air to the side of the vehicle
facing the sun. The recirculation mode will also
be used as needed to maintain cool outlet
temperatures.
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 mode up and down arrows to select
the defog mode. Use the defrost button to
select the 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
close to freezing. The recirculation mode cannot
be selected while in the defog mode. Do not
drive the vehicle until all the windows are clear.
0(Defrost):Press this button 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
automatically forces outside air into your vehicle.
The recirculation mode cannot be selected
while in the defrost mode. The air conditioning
compressor runs automatically in this setting,
unless the outside temperature is close to freezing.
Do not drive the vehicle until all the windows
are clear.
209
