OnStar service cannot work unless
the 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 the vehicle is 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 the
vehicle is only available if the GPS
satellite signals are unobstructed
and available.
The vehicle must have a working
electrical system, including adequate
battery power, for the OnStar
equipment to operate. There are
other problems OnStar cannotcontrol that may prevent OnStar
from providing OnStar service at
any particular time or place.
Some examples are damage to
important parts of the vehicle in a
crash, hills, tall buildings, tunnels,
weather or wireless phone network
congestion.
Your Responsibility
Increase the volume of the radio
if the OnStar advisor cannot
be heard. If the light next to the
OnStar buttons is red, the system
may not be functioning properly.
Press the OnStar button and request
a vehicle diagnostic. If the light
appears clear (no light is appearing),

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.

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 times out and you
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 erases 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 the 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 the 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 ashes
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 the 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.
6. After Steps 1 through 5 have
been completed, locate inside
the garage the garage door
opener receiver (motor-head
unit). Locate the “Learn” or
“Smart” button. The name and
color of the button may vary by
manufacturer.

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.
