light GMC ACADIA 2007 Workshop Manual

The HUD information appears as an image
focused out toward the front of the vehicle.
When the ignition key is turned to RUN, the HUD
will display an introductory message for a short
time, until the HUD is ready.
The following indicator lights come on the
instrument panel when activated and will also
appear on the HUD:
Turn Signal Indicators
High-Beam Indicator SymbolThe HUD will temporarily display CHECK GAGES
and ICE POSSIBLE when there are messages
on the DIC trip computer.
The HUD will also display the following messages
when these systems are active:
TRACTION CONTROL ACTIVE
STABILITRAK ACTIVE
Notice:If you try to use the HUD image as a
parking aid, you may misjudge the distance
and damage your vehicle. Do not use the
HUD image as a parking aid.
When the HUD is on, the speedometer reading
will continually be displayed. The current radio
station or CD track number will display for a short
period of time after the radio or CD track status
changes. This will happen whenever radio
information is changed. The speedometer size
will be reduced when radio, CD information,
warnings, or turn-by-turn navigation information
are displayed on the HUD.
191

Format Two:This display includes the information
in Format One without the transmission information
and the outside air temperature.
Format Three:This display includes all the
information in Format One along with a circular
tachometer, but without outside air temperature.
All formats will show the turn-by-turn navigation
information and provide details about the next
driving maneuver to be made. When you near your
destination, the HUD will display a distance bar
that will ll in the closer you get to your destination.All navigation information is provided to the HUD
by the navigation radio, if the vehicle has one.
The HUD image displayed on the windshield will
automatically dim and brighten to compensate
for outside lighting.
The HUD image can temporarily light up
depending on the angle and position of the
sunlight on the HUD display. This is normal and
will change when the angle of the sunlight on
the HUD display changes.
Polarized sunglasses could make the HUD image
harder to see.
Care of the HUD
Clean the inside of the windshield as needed to
remove any dirt or lm that could reduce the
sharpness or clarity of the HUD image.
To clean the HUD lens, use a soft, clean cloth
that has household glass cleaner sprayed
on it. Wipe the HUD lens gently, then dry it.
Do not spray cleaner directly on the lens
because the cleaner could leak into the unit.

{CAUTION:
The Ultrasonic Rear Park Assist (URPA)
system does not replace driver vision.
URPA does not:
Operate above speeds of
5 mph (8 km/h).
Detect objects more than 8 feet
(2.5 meters) behind the vehicle. This
distance may be less during warmer
or humid weather.
Detect objects that are below the
bumper, underneath the vehicle, or
that are very close to the vehicle.
Detect children, pedestrians,
bicyclists, or pets.
So if you do not use proper care before
backing up, you could hit a vehicle, child,
pedestrian, bicyclist, or pet, resulting in
vehicle damage, injury, or death. Even
though the vehicle has the URPA system,
always check carefully before backing up
by checking behind your vehicle.The URPA display is
located in the headliner
and can be seen by
looking over your right
shoulder.
The URPA display has three color-coded lights.
The lights are used to provide distance and system
information, along with beeps that will be heard
through the speakers.
The red light in the URPA display will be lit if the
vehicle is in REVERSE (R). If the vehicle has a
Driver Information Center (DIC), PARK ASSIST
OFF will display on the DIC when the vehicle has
been started and shifted out of PARK (P). SeeDIC
Warnings and Messages on page 244for more
information.
How the System Works
When the shift lever is moved into REVERSE (R),
the rear display will briey come on to let you
know the display is operating correctly. URPA
comes on automatically when the shift lever
is moved into REVERSE (R).
195

The system does not work at a reverse speed
greater than 5 mph (8 km/h). To remind you of this,
the red light on the rear display will ash.
To disable URPA, seeDIC Operation and Displays
(With DIC Buttons) on page 233andDIC
Operations and Displays (Without DIC Buttons)
on page 239.
URPA automatically turns back on each time
the vehicle is started.
How the System Works when Backing
If the shift lever is in REVERSE (R), URPA
detects objects close to the rear bumper. The
rst time an object is detected a single beep will
sound. If an object is detected at a REVERSE (R)
speed between 0 mph (0 km/h) and 5 mph
(8 km/h), the following describes what will occur
based on your distance to a detected object
located behind the vehicle:
At distances between 40 inches (1 m) and 8 ft
(2.5 m), a single amber light will come on.
At distances between 23 inches (0.6 m) and
40 inches (1 m), both amber lights will be on.
At distances between 12 inches (0.3 m) and
23 inches (0.6 m), all three lights (amber/
amber/red) will be on.
At distances less than 12 inches (0.3 m), a
beeping sound will repeat for a short time and
all three lights (amber/amber/red) will ash.
When the System Does Not Seem to
Work Properly
If the URPA system will not activate due to a
temporary condition, the message PARK ASSIST
OFF will display on the DIC screen and a red
light will come on the URPA display when the shift
lever is moved into REVERSE (R). This occurs
under the following conditions:
The parking brake pedal is depressed.
A trailer was attached to your vehicle, or a
bicycle or an object was hanging out of
your trunk during your last drive when you
turned off the vehicle. If the attached objects
are removed from your vehicle before the start
of your next drive, the system will return to
normal operation unless an object is detected
when the vehicle is shifted into REVERSE (R).

Temperature Control:Turn the center knob
clockwise or counterclockwise to increase
or decrease the temperature of the air owing
from the system.
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.
200

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

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

Manual Operation
The air delivery mode or fan speed can be
manually adjusted.
DC(Fan):The buttons with the fan symbols let
you manually adjust the fan speed. Press the
up arrow to increase fan speed and the down
arrow to decrease fan speed.
Pressing a fan button while the system is off will
turn the system on. Pressing a fan button
while in automatic control places the fan under
manual control. The fan setting remains displayed
and the AUTO light turns off. The air delivery
mode remains in automatic control.
yNz(Mode):Press the mode up and down
buttons to manually change the direction of
the airow in the vehicle. Repeatedly press the
button until the desired mode appears on the
display. Pressing a mode button while the system
is off will change air delivery mode without
turning the system on. Press one of these buttons
while in automatic control to place the mode
under manual control.The air delivery mode setting displays and the
AUTO light turns off. The fan remains under
automatic control.
H(Vent):This setting delivers air to the
instrument panel outlets.
)(Bi-Level):This mode directs air to the
instrument panel outlets and 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 in oor mode.
-(Defog):See “Defogging and Defrosting” later
in this section.
@(Recirculation):Press this button to turn
the recirculation mode on. When the button
is pressed, an indicator light comes on.
206

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

Mode Knob
The right knob on the control panel lets you
choose 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.
Rear Air Conditioning and
Heating System and Electronic
Climate Controls
If your vehicle has this rear climate control system
there are rear seat audio controls located in the
center console.
The rear system can be controlled through the
AUX button on the front climate control panel.
Press the AUX button to turn the rear climate
