2007 GMC ACADIA light

Entry Lighting
Your vehicle may have courtesy lamps that will
come on and stay on for a set time whenever
the unlock symbol is pressed on the Remote
Keyless Entry (RKE) Transmitter, if the vehicle
has one.
If a door is opened, the lamps will stay on while
it is open and then turn off automatically about
25 seconds after the door is closed. If the
unlock symbol is pressed and you do not
open a door, the lamps will turn off after about
20 seconds.
Entry lighting includes a feature called theater
dimming. With theater dimming, the lamps do not
turn off at the end of the delay time. Instead,
they slowly dim after the delay time until they go
out. The delay time is canceled if you turn the
ignition key to ON or press the power door
lock switch. The lamps will dim right away.
When the ignition is on, illuminated entry is
inactive, which means the courtesy lamps will
not come on unless a door is opened.
Delayed Entry Lighting
Delayed entry lighting illuminates the interior for
a period of time after all the doors have been
closed.
The ignition must be off for delayed entry lighting
to work. Immediately after all the doors have
been closed, the delayed entry lighting feature
will continue to work until one of the following
occurs:
The ignition is in ON.
The doors are locked.
An illumination period of 25 seconds
has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled
and the interior lamps will remain on because a
door is open.
187

Delayed Exit Lighting
This feature illuminates the interior for a period of
time after the key is removed from the ignition.
The ignition must be off for delayed exit lighting to
work. When the key is removed, interior illumination
will activate and remain on until one of the following
occurs:
The ignition is in ON.
The power door locks are activated.
An illumination period of 20 seconds
has elapsed.
If during the illumination period a door is opened,
the timed illumination period will be canceled
and the interior lamps will remain on because a
door is open.
Parade Dimming
The instrument panel has an added feature called
parade mode. It automatically prohibits the
dimming of the instrument panel displays during
the daylight while the headlamps are on so
that you will still be able to see the displays.
Reading Lamps
The vehicle has reading lamps that also act as the
dome lamp. Press the button to turn them on and off.
Electric Power Management
The vehicle has Electric Power Management (EPM)
that estimates the battery’s temperature and state
of charge. It then adjusts the voltage for best
performance and extended life of the battery.
When the battery’s state of charge is low, the
voltage is raised slightly to quickly put the charge
back in. When the state of charge is high, the
voltage is lowered slightly to prevent overcharging.
If the vehicle has a voltmeter gage or voltage
display on the Driver Information Center (DIC),
you may see the voltage move up or down. This
is normal. If there is a problem, an alert will be
displayed.
The battery can be discharged at idle if the
electrical loads are very high. This is true for all
vehicles. This is because the generator (alternator)
may not be spinning fast enough at idle to
produce all the power that is needed for very
high electrical loads.
188

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.

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.
