Integrated HomeLink® Wireless Control
System
The HomeLink® Wireless Control System
provides a convenient way to replace
up to three hand held radio-frequency
transmitters used to activate compatible
devices such as gate operators, garage
door openers, entry door locks, security
systems, and home lighting.
NOTICE
HomeLink® operates while the ignition
switch is in the ACC or ON position
for safety reasons. It is to prevent
unintentional security problems from
happening when the vehicle is parked
outside the garage.
WARNING
Before programming HomeLink® to a
garage door opener or gate operator,
make sure people and objects are out
of the way of the device to prevent
potential harm or damage. Do not
use the HomeLink® with any garage
door opener that lacks the safety
stop and reverse features required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an
object - signaling the door to stop and
reverse - does not meet current U.S.
federal safety standards. Using a garage
door opener without these features
increases the risk of serious injury or
death.
For more information, contact
HomeLink® at www.homelink.com, or
call Home-Link customer support at
1-800-355-3515.
It is also recommended that a new
battery be replaced in the handheld
transmitter of the device being trained
to HomeLink® for quicker training and
accurate transmission of the radio
frequency. 1. Programming HomeLink
®
The following steps show how to
program HomeLink. If you have any
questions or are having difficulty
programming your HomeLink buttons,
refer to the HomeLink website or call the
HomeLink customer support toll-free
number. Do this before going back to the
dealer who sold you the car.
