114 Instruments and Controls
Universal Remote System
Programming
If equipped, these buttons are in the
overhead console.
This system can replace up to three remote
control transmitters used to activate devices
such as garage door openers, security
systems, and home automation devices.
These instructions refer to a garage door
opener, but can be used for other devices.
Do not use the Universal Remote system
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 these instructions completely before
programming the Universal Remote system.
It may help to have another person assist
with the programming process.
Keep the original hand-held transmitter for
use in other vehicles as well as for future
programming. Erase the programming when
vehicle ownership is terminated. See
“Erasing Universal Remote System Buttons”
later in this section.
To program a garage door opener, park
outside directly in line with and facing the
garage door opener receiver. Clear all people
and objects near the garage door.
Make sure the hand-held transmitter has a
new battery for quick and accurate
transmission of the radio-frequency signal.
Programming the Universal Remote
System
For questions or programming help, see
www.homelink.com/gm or call
1-800-355-3515.
Programming involves time-sensitive actions,
and may time out causing the procedure to
be repeated.
To program up to three devices:
1. Hold the end of the hand-held transmitter about 3 to 8 cm (1 to 3 in)
away from the Universal Remote system
buttons with the indicator light in view.
The hand-held transmitter was supplied
by the manufacturer of the garage door
opener receiver.
2. Press and release one of the three Universal Remote system buttons to be
programmed. Press and hold the
hand-held transmitter button. Do not
release the hand-held transmitter button
until the indicator light changes from a
slow to a rapid flash or continuous light.
Then release the hand-held transmitter
button.
Some garage door openers may require
substitution of Step 2 with the procedure
under “Radio Signals for Some Gate
Operators” later in this section.

3. Press and hold the newly programmedUniversal Remote system button for
five seconds while watching the indicator
light and garage door activation.
.If the indicator light stays on
continuously or the garage door
moves when the button is pressed,
then programming is complete. There
is no need to complete Steps 4–6.
.If the indicator light does not come
on or the garage door does not
move, a second button press may be
required. For a second time, press
and hold the newly programmed
button for five seconds. If the
indicator light is continuously lit,
or the garage door moves,
programming is complete.
.If the indicator light flashes rapidly
and the garage door does not move,
continue with programming
Steps 4–6.
Learn or Smart Button
4. After completing Steps 1–3, locate the Learn or Smart button inside the garage
on the garage door opener receiver. The
name and color of the button may vary
by manufacturer.
5. Press and release the Learn or Smart button. Step 6 must be completed within
30 seconds of pressing this button.
6. Return to the vehicle and firmly press and hold the trained Universal Remote
system button for two seconds and
release. Repeat the “press/hold/release”
sequence up to three times to complete
the training process.
The Universal Remote system should now
activate the garage door.
Repeat the process for programming the
two remaining buttons.
Radio Signals for Some Gate Operators
For questions or programming help, see
www.homelink.com/gm or call
1-800-355-3515.
Some radio–frequency laws and gate
operators require transmitter signals to time
out or quit after several seconds of
transmission. This may not be long enough
for the Universal Remote system to pick up
the signal during programming.
If the programming did not work, replace
Step 2 under “Programming the Universal
Remote System” with the following:
Press and hold the Universal Remote system
button while pressing and releasing the
hand-held transmitter button every
two seconds until the signal has been
successfully accepted by the Universal
Remote system. The Universal Remote
system indicator light will flash slowly at
first and then change to a rapid flash or
continuous solid-light. Proceed with Step 3
under “Programming the Universal Remote
System” to complete.
