automation devices. These

Cadillac CT4 Owner Manual (GMNA-Localizing-U.S./Canada-13183937) -

122 INSTRUMENTS AND CONTROLS
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

INSTRUMENTS AND CONTROLS 123
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.
. 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.
