WARNING
∙ Your vehicle’s engine should beturned off while programming the
HomeLink® Universal Transceiver. For
additional information, refer to
“Push-button ignition switch” in the
“Starting and driving” section of this
manual. Do not breathe exhaust
gases; they contain colorless and
odorless carbon monoxide. Carbon
monoxide is dangerous. It can cause
unconsciousness 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 de-
tect an object in the path of a closing
garage door and then automatically
stop and reverse does not meet cur-
rent federal safety standards. Using 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 posi-
tion (without starting the engine) when
programming HomeLink®. It is also rec-
ommended that a new battery be placed
in the hand-held transmitter of the de-
vice 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
1in view.

WARNING
∙ Never allow anyone to ride in thecargo area or on the rear seat when it
is in the fold-down position. Use of
these areas by passengers without
proper restraints could result in seri-
ous injury or death in an accident or
sudden stop.
∙ Properly secure all cargo with ropes or straps to help prevent it from sliding
or shif ting. Do not place cargo higher
than the seatbacks. In a sudden stop
or collision, unsecured cargo could
cause personal injury.
∙ When returning the seatbacks to the upright position, be certain they are
completely secured in the latched po-
sition. If they are not completely se-
cured, passengers may be injured in
an accident or sudden stop.
∙ Closely supervise children when they are around cars to prevent them from
playing and becoming locked in the
trunk where they could be seriously
injured. Keep the car locked, with the
rear seatback and trunk lid securely
latched when not in use, and prevent
children’s access to car keys.
