WARNING
• Your vehicle's engine should be
turned off while programming the
HomeLink® Universal Transceiver. For
additional information, see “Push-
button ignition switch” (P. 5-12). Do
not breathe exhaust gases; they con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconscious-
ness or death.
• Do not use the HomeLink® Universal
Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982.) A
garage door opener which cannot
detect an object in the path of a clos-
ing garage door and then automati-
cally stop and reverse does not meet
current federal safety standards. Us-
ing a garage door opener without
these features increases the risk of
serious injury or death. •
During the programming procedure
your garage door or security gate will
open and close (if the transmitter is
within range). Make sure that people
or objects are clear of the garage
door, gate, etc., that you are
programming.
PROGRAMMING HOMELINK®
If you have any questions or are having
difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site at:
www.homelink.com or call 1-800-355-3515.
NOTE:
Place the ignition switch in the ON or ACC
position (without starting the engine)
when programming HomeLink®. It is also
recommended that a new battery be
placed in the hand-held transmitter of
the device being programmed to
HomeLink® for quicker programming
and accurate transmission of the radio
frequency. 1. Position the end of your hand-held
transmitter 1–3 in (2–8 cm) away from
the HomeLink® surface, keeping the
HomeLink® indicator light
O1in view.
