2008 GMC ACADIA light

When the System Does Not Seem to
Work Properly
The driver disables the system.
The parking brake pedal is depressed.
The ultrasonic sensors are not clean. Keep your
vehicle’s rear bumper free of mud, dirt, snow,
ice and slush. For cleaning instructions, see
Washing Your Vehicle on page 5-92.
A trailer was attached to your vehicle, or a bicycle
or an object was hanging out of your liftgate
during your last drive cycle, the red light may
illuminate in the rear display. Once the attached
object is removed, URPA will return to normal
operation.
A tow bar is attached to your vehicle.
The vehicle’s bumper is damaged. Take the vehicle
to your dealer/retailer to repair the system.
Other conditions may affect system performance,
such as vibrations from a jackhammer or the
compression of air brakes on a very large truck.
If the system is still disabled, after driving forward at
least 15 mph (25 km/h), take your vehicle to your
dealer/retailer.
Rear Vision Camera
Your vehicle may have a Rear Vision Camera system.
Read the entire section before using the system.
The rear vision camera system is designed to help the
driver when backing up. See “Rear Vision Camera”
in the Index of the navigation manual.
OnStar®System
OnStar uses several innovative technologies and live
advisors to provide you with a wide range of safety,
security, information, and convenience services. If your
airbags deploy, the system is designed to make an
automatic call to OnStar Emergency advisors who can
request emergency services be sent to your location.
If you lock your keys in the vehicle, call OnStar at
1-888-4-ONSTAR and they can send a signal to unlock
your doors. If you need roadside assistance, press
the OnStar button and they can contact Roadside
Service for you.

OnStar service cannot work unless your vehicle is in a
place where OnStar has an agreement with a wireless
service provider for service in that area. OnStar
service also cannot work unless you are in a place
where the wireless service provider OnStar has hired for
that area has coverage, network capacity and reception
when the service is needed, and technology that is
compatible with the OnStar service. Not all services are
available everywhere, particularly in remote or
enclosed areas, or at all times.
Location information about your vehicle is only available if
the GPS satellite signals are unobstructed and available.
Your vehicle must have a working electrical system
(including adequate battery power) for the OnStar
equipment to operate. There are other problems OnStar
cannot control that may prevent OnStar from providing
OnStar service to you at any particular time or place.
Some examples are damage to important parts of your
vehicle in an accident, hills, tall buildings, tunnels,
weather or wireless phone network congestion.
Your Responsibility
Increase the radio volume if you cannot hear the OnStar
advisor. If the light next to the OnStar buttons is red, this
means that your system is not functioning properly and
should be checked by your dealer/retailer. If the light
appears clear (no light is appearing), your OnStar
subscription has expired. You can always press the
OnStar button to conrm that your OnStar equipment is
active.

Universal Home Remote System
Operation (With One Triangular LED)
If there is one triangular Light Emitting Diode (LED)
indicator light above the Universal Home Remote
buttons, follow the instructions below.
This system provides a way to replace up to three
remote control transmitters used to activate devices
such as garage door openers, security systems,
and home automation devices.
Do not use the Universal Home Remote with any
garage door opener that does not have the stop and
reverse feature. This includes any garage door opener
model manufactured before April 1, 1982.
Read the instructions completely before attempting to
program the Universal Home Remote. Because of
the steps involved, it may be helpful to have another
person available to assist you in the programming
the Universal Home Remote.Keep the original hand-held transmitter for use in other
vehicles as well as for future Universal Home Remote
programming. It is also recommended that upon the sale
of the vehicle, the programmed Universal Home
Remote buttons should be erased for security purposes.
See “Erasing Universal Home Remote Buttons” later
in this section.
When programming a garage door, park outside of the
garage. Park directly in line with and facing the
garage door opener motor-head or gate motor-head. Be
sure that people and objects are clear of the garage
door or gate you are programming.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.
Programming the Universal Home
Remote System
If you have questions or need help programming the
Universal Home Remote System, call 1-800-355-3515 or
go to www.homelink.com.
Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before you begin. If you do not follow these actions, the
device will time out and you will have to repeat the
procedure.
2-51

To program up to three devices:
1. From inside the vehicle, press and hold down the
two outside buttons at the same time, releasing
only when the Universal Home Remote indicator
light begins to ash, after 20 seconds. This step will
erase the factory settings or all previously
programmed buttons.
Do not hold down the buttons for longer than
30 seconds and do not repeat this step to program
the remaining two Universal Home Remote
buttons.
2. Hold the end of your hand-held transmitter about 1
to 3 inches (3 to 8 cm) away from the Universal
Home Remote buttons while keeping the indicator
light in view. The hand-held transmitter was
supplied by the manufacturer of your garage door
opener receiver (motor head unit).
3. At the same time, press and hold both the Universal
Home Remote button that you would like to use to
control the garage door and the hand-heldtransmitter button. Do not release the Universal
Home Remote button or the hand-held transmitter
button until Step 4 has been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
4. The indicator light on the Universal Home Remote
will ash slowly at rst and then rapidly after
Universal Home Remote successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained Universal Home
Remote button and observe the indicator light.
If the indicator light stays on continuously,
the programming is complete and your garage door
should move when the Universal Home Remote
button is pressed and released. You do not need to
continue the programming Steps 6 through 8 and
can stop here.
If the Universal Home Remote indicator light blinks
rapidly for two seconds and then turns to a
constant light, continue with the programming Steps
6 through 8.
It may be helpful to have another person available
to assist with the remaining steps.

Gate Operator and Canadian
Programming
If you have questions or need help programming the
Universal Home Remote System, call 1-800-355-3515 or
go to www.homelink.com.
Canadian radio-frequency laws require transmitter
signals to time out or quit after several seconds of
transmission. This may not be long enough for Universal
Home Remote to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
time out in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator or garage door opener by
using the “Programming Universal Home Remote”
procedures, regardless of where you live, replace Step 3
under “Programming Universal Home Remote” with the
following:
Continue to press and hold the Universal Home Remote
button while you press and release every two seconds
(cycle) the hand-held transmitter button until the
frequency signal has been successfully accepted by the
Universal Home Remote. The Universal Home Remote
indicator light will ash slowly at rst and then rapidly.
Proceed with Step 4 under “Programming Universal
Home Remote” to complete.
Using Universal Home Remote
Press and hold the appropriate Universal Home Remote
button for at least half of a second. The indicator light
will come on while the signal is being transmitted.
Erasing Universal Home Remote
Buttons
Erase the programmed buttons when you sell or
terminate your lease.
To erase all programmed buttons on the Universal
Home Remote device:
1. Press and hold down the two outside buttons until
the indicator light begins to ash, after 20 seconds.
2. Release both buttons.

If a bulb is burned out, replace it to help avoid an
accident. If the arrows do not go on at all when you
signal a turn, check for burned-out bulbs and then check
the fuse. SeeFuses and Circuit Breakers on
page 5-100.
Turn Signal On Chime
If either one of the turn signals are left on and you have
drove more than 3/4 mile (1.2 km), a chime will sound.
Headlamp High/Low-Beam
Changer
To change the headlamps from low beam to high beam,
push the turn signal/multifunction lever toward the
front of the vehicle.
This light on the instrument
panel cluster comes on
if the high beam lamps
are turned on while
the ignition is on.
To change the headlamps from high beam to low beam,
pull the turn signal lever toward the rear of the vehicle.
Flash-to-Pass
With the turn signal lever in the low-beam position,
pull the lever toward you momentarily to switch
to high-beam, to signal that you are going to pass.
If the headlamps are on, they will return to low-beam
when the lever is released.
Windshield Wipers
Clear ice and snow from the wiper blades before
using them. If they are frozen to the windshield, gently
loosen or thaw them. Damaged wiper blades may
not clear the windshield well, making it harder to see
and drive safely. If the blades do become damaged,
install new blades or blade inserts. For more information,
seeWindshield Wiper Blade Replacement on page 5-47.
Heavy snow or ice can overload the wiper motor.
A circuit breaker will stop the motor until it cools down.
Clear away snow or ice to prevent an overload.
Turn the band with the wiper symbol to control the
windshield wipers.
