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. For calls placed
outside the U.S., Canada, or Puerto
Rico, international rates will apply and
may differ based on landline or mobile
phone.
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. At the same time, press and hold both the hand-held transmitter
button and one of the three
Universal Remote system buttons
to be used to operate the garage
door. Do not release either button until the indicator light changes
from a slow to a rapid flash. Then
release both buttons.
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 programmed Universal 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 light stays
on or the garage door moves,
programming is complete.

124 INSTRUMENTS AND CONTROLS
.If the indicator light blinks
rapidly for two seconds, then
changes to a solid light 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
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. Inside the vehicle, press and hold the newly programmed Universal
Remote system button for
two seconds and then release it. If the garage door does not move
or the lamp on the garage door
opener receiver does not flash,
press and hold the same button a
second time for two seconds, then
release it. Again, if the door does
not move or the garage door lamp
does not flash, press and hold the
same button a third time for
two seconds, then release it.
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. For calls placed
outside the U.S., Canada, or Puerto
Rico, international rates will apply and
may differ based on landline or mobile
phone.
Some gate operators and
radio-frequency laws 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
rapidly. Proceed with Step 3 under
“Programming the Universal Remote
System ”to complete.
Universal Remote System
Operation
Using the Universal Remote
System
Press and hold the appropriate
Universal Remote system button for at
least one-half second. The indicator
light will come on while the signal is
being transmitted.

beams when driving over 40 km/h
(25 mph).
The blue high-beam on light appears
on the instrument cluster when the
high beams are on. There is a sensor near the top center
of the windshield that automatically
controls the system. Keep this area of
the windshield clear of debris to allow
for best system performance.
The high-beam headlamps remain on,
under the automatic control, until one
of the following situations occurs:
.The system detects an approaching
vehicle's headlamps.
.The system detects a preceding
vehicle's taillamps.
.The outside light is bright enough
that high-beam headlamps are not
required.

system is reactivated. The high beams may not turn off
automatically if the system cannot
detect another vehicle's lamps because
of any of the following:
.The other vehicle's lamps are
missing, damaged, obstructed from
view, or otherwise undetected.
.The other vehicle's lamps are
covered with dirt, snow, and/or road
spray.
.The other vehicle's lamps cannot be
detected due to dense exhaust,
smoke, fog, snow, road spray, mist,
or other airborne obstructions.
.The vehicle's windshield is dirty,
cracked, or obstructed by something
that blocks the view of the light
sensor.
.The vehicle is loaded such that the
front end points upward, causing
the light sensor to aim high and not
detect headlamps and taillamps.
.The vehicle is being driven on
winding or hilly roads.
The automatic high-beam headlamps
may need to be disabled if any of the
above conditions exist.
