OnStar Steering Wheel Controls
Your vehicle may have a Talk/Mute button that can
be used to interact with OnStar Hands-Free Calling.
SeeAudio Steering Wheel Controls on page 3-124for
more information.
On some vehicles, you may have to hold the button for
a few seconds and give the command “ONSTAR” to
activate the OnStar Hands-Free Calling.
On some vehicles, the mute button can be used to
dial numbers into voicemail systems, or to dial phone
extensions. See the OnStar Owner’s Guide for
more information.
How OnStar Service Works
Your vehicle’s OnStar system has the capability
of recording and transmitting vehicle information.
This information is automatically sent to an OnStar
Call Center at the time of an OnStar button press,
Emergency button press or if your airbags or AACN
system deploys. The vehicle information usually includes
your GPS location and, in the event of a crash, additional
information regarding the accident that your vehicle has
been involved in (e.g. the direction from which your
vehicle was hit). When you use the Virtual Advisor feature
of OnStar Hands-Free Calling, your vehicle also sends
OnStar your GPS location so that we can provide you
with location-based services.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.
2-58

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
that is being programmed.
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
For questions or 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 starting. Otherwise, the device will time out and
the procedure will have to be repeated.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).

8. Immediately return to the vehicle. Firmly press and
hold the Universal Home Remote button, chosen in
Step 3 to control the garage door, for two seconds,
and then release it. If the garage door does not
move, press and hold the same button a second time
for two seconds, and then release it. Again, if the
door does not move, press and hold the same button
a third time for two seconds, and then release.
The Universal Home Remote should now activate
the garage door.
To program the remaining two Universal Home Remote
buttons, begin with Step 2 of “Programming the Universal
Home Remote System.” Do not repeat Step 1, as this will
erase all previous programming from the Universal Home
Remote buttons.
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 UniversalHome 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.
