2007 GMC ACADIA sensor

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.

Sensors
The solar sensor, located in the defrost grille in
the middle of the instrument panel, monitors
the solar radiation. Do not cover the solar sensor
or the system will not work properly.The interior temperature sensor located on the
instrument panel to the right of the steering column,
measures the temperature of the air inside the
vehicle.
There is also an exterior temperature sensor
located behind the front grille. This sensor reads
the outside air temperature and helps maintain
the temperature inside the vehicle. Any cover on
the front of the vehicle could cause a false reading
in the displayed temperature.
208

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.

Passenger Safety Belt
Reminder Light
Several seconds after the key is turned to ON or
START, a chime will sound for several seconds
to remind the front passenger to buckle their
safety belt. This would only occur if the passenger
airbag is enabled. SeePassenger Sensing
System on page 85for more information. The
passenger safety belt light will also come on
and stay on for several seconds, then it will ash
for several more.
This chime and light
are repeated if the
passenger remains
unbuckled and
the vehicle is
in motion.
If the passenger’s safety belt is buckled,
neither the chime nor the light will come on.
Airbag Readiness Light
There is an airbag readiness light on the
instrument panel cluster, which shows the
airbag symbol. The system checks the airbag’s
electrical system for malfunctions. The light
tells you if there is an electrical problem.
The system check includes the airbag sensor,
the pretensioners, the airbag modules, the wiring
and the crash sensing and diagnostic module.
For more information on the airbag system,
seeAirbag System on page 76.
This light will come on
when you start your
vehicle, and it will ash
for a few seconds.
Then the light should
go out. This means
the system is ready.
