Cadillac 2008 SRX Owner's Manual page 129

Do not use this 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 the instructions completely before attempting to
program the transmitter. Because of the steps involved,
it may be helpful to have another person available to
assist you in programming the transmitter.
Be sure to keep the original remote control transmitter
for use in other vehicles, as well as, for future
programming. You only need the original remote control
transmitter for Fixed Code programming. It is also
recommended that upon the sale or lease termination
of the vehicle, the programmed buttons should be
erased for security purposes. See "Erasing Universal
Home Remote Buttons" later in this section.
When programming a garage door, it is advised to
park outside of the garage. Be sure that people
and objects are clear of the garage door or security
device you are programming.

To program up to three devices:
