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. 2. Using both hands, simultaneously press
and hold the desired HomeLink® button
and hand-held transmitter button. DO
NOT release until the HomeLink® indica-
tor light
O1flashes slowly and then rap-
idly. When the indicator light flashes rap-
idly, both buttons may be released. (The
rapid flashing indicates successful
programming.)
NOTE:
Some devices may require you to replace
Step 2 with the cycling procedure noted
in “Programming HomeLink® for gate
openers” (P. 2-92).
