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.

the Universal Home Remote.
2-52

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.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-held
transmitter 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.
