■Before programming HomeLink®
●During programming, it is possible that garage doors, gates, or other
devices may operate. For this reason, make sure that people and objects
are clear of the garage door or other devices to prevent injury or other
potential harm.
●It is recommended that a new battery be placed in the remote control
transmitter for more accurate programming.
●Garage door opener motors manufactured after 1995 may be equipped
with rolling code protection. If this is the case, you may need a stepladder
or other sturdy, safe device to reach the “Learn” or “Smart” button on the
garage door opener motor.
The garage door opener can be programmed to operate garage doors, gates,
entry doors, door locks, home lighting systems, security systems, and other
devices.

■Replacing light bulbs
●Turn off the lights. Do not attempt to replace the bulb immediately after turning off the
lights.
The bulbs become very hot and may cause burns.
●Do not touch the glass portion of the light bulb with bare hands. When it is unavoid-
able to hold the glass portion, use and hold with a clean dry cloth to avoid getting
moisture and oils on the bulb.
Also, if the bulb is scratched or dropped, it may blow out or crack.
●Fully install light bulbs and any parts used to secure them. Failure to do so may result
in heat damage, fire, or water entering the headlight unit. This may damage the head-
lights or cause condensation to build up on the lens.
■To prevent damage or fire
●Make sure bulbs are fully seated and locked.
●Check the wattage of the bulb before installin g to prevent heat damage.
