2008 GMC ACADIA display

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.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 this mode is selected,
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.

To clear fog from the rear seat side windows, select the
bi-level mode on the rear climate control system and
direct the headliner outlets toward the side windows.
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 the 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.
While in defrost mode, if the PASS button is pressed,
the PASS button indicator will ash three times to
let you know that the passenger climate control system
cannot be activated. If the passenger temperature
buttons are adjusted while in defrost mode, the driver
temperature indicator will change. The passenger
temperature will not be displayed.

rear heating and air conditioning on. SeeRear Air
Conditioning and Heating System on page 3-36or
Rear Air Conditioning and Heating System and
Electronic Climate Controls on page 3-38.
Rear Window Defogger
The rear window defogger uses a warming grid to
remove fog from the rear window.
<(Rear Window Defogger):Press this button to
turn the rear window defogger on or off. The rear
window defogger stays on for about 10 minutes after
the button is pressed, before turning off. The defogger
can also be turned off by pressing the button again
or by turning off the engine. Do not drive the vehicle
until all the windows are clear.
If your vehicle has heated outside rearview mirrors,
the mirrors will heat to help clear fog or frost from the
surface of the mirror when the rear window defog
button is pressed.
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.

Warning Lights, Gages,
and Indicators
This section describes the warning lights and gages
on your vehicle.
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 also save you
or others from injury.Warning lights come on when there may be or is
a problem with one of your vehicle’s functions. As the
details show on the next few pages, some warning lights
come on briey when you start the engine just to let
you know they are working. If you are familiar with
this section, you should not be alarmed when this
happens.
Gages can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know
when there is a problem with your vehicle.
When one of the warning lights comes on and stays
on as you are driving, or when one of the gages shows
there may be a problem, check the section that tells
you what to do about it. Please follow this manual’s
advice. Waiting to do repairs can be costly and even
dangerous. So get to know your vehicle’s warning lights
and gages. They can be a big help.

The speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
The odometer shows how far your vehicle has been
driven, in either miles or kilometers.
Your vehicle has a tamper-resistant odometer. If your
vehicle needs a new odometer installed, the new
one will be set to the mileage total of the old odometer.
If this is not possible, it will be set at zero and a
label must be put on the driver’s door to show the
old mileage reading when the new odometer was
installed. If the mileage is unknown, the label should
then indicate “previous mileage unknown”.
Tachometer
The tachometer displays the engine speed in
revolutions per minute (rpm).
Safety Belt Reminders
Safety Belt Reminder Light
When the engine is started, a chime will come on for
several seconds to remind people to fasten their safety
belts, unless the driver’s safety belt is already buckled.
The safety belt light
will also come on and stay
on for several seconds,
then it will ash for
several more.
This chime and light is repeated if the driver remains
unbuckled and the vehicle is in motion. If the driver’s
belt is already buckled, neither the chime nor the
light will come on.
