Universal Home Remote System

Operation (With Three Round LED)
This vehicle may have the Universal Home Remote
System. If there are three round Light Emitting
Diode (LED) indicator lights above the Universal
Home Remote buttons, follow the instructions below.
This system provides a way to replace up to
three remote control transmitters used to activate
devices such as garage door openers, security
systems, and home automation devices.
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 assist with
programming the transmitter.

Be sure to keep the original remote control transmitter for
use in other vehicles, as well as, for future programming.
Only the original remote control transmitter is needed for
Fixed Code programming. The programmed buttons
should be erased when the vehicle is sold or the lease
ends. See "Erasing Universal Home Remote Buttons"
later in this section.
Park the vehicle outside of the garage when
programming a garage door. Be sure that people and
objects are clear of the garage door or gate that is
being programmed.

Most garage door openers sold after 1996 are

Programming a garage door opener involves
time-sensitive actions, so read the entire procedure
before starting. Otherwise, the device will time out
and the procedure will have to be repeated.
