Before You Begin Programming
HomeLink
For efficient programming and accurate
transmission of the radio-frequency signal, it
is recommended that a new battery be placed
in the hand-held transmitter of the device
that is being programmed to the HomeLink
system. Make sure your hand-held transmit-
ter is programmed to activate the device you
are trying to program your HomeLink button
to.
Ensure that your vehicle is parked outside of
the garage before you begin programming.

It is recommended that you erase all the
channels of your HomeLink before you use it
for the first time.
If you have any problems, or require assis-
tance, please call toll-free 1-800-355-3515
or, on the Internet at HomeLink.com for in-
formation or assistance.

Erasing All The HomeLink Channels

To erase the channels, follow this procedure:
1. Place the ignition switch into the ON/RUN
position.
2. Push and hold the two outside HomeLink
buttons (I and III) for up to 20 seconds, or
until the HomeLink indicator
flashes.
NOTE:
Erasing all channels should only be per-
formed when programming HomeLink for the
first time. Do not erase channels when pro-
gramming additional buttons.
Identifying Whether You Have A Rolling
Code Or Non-Rolling Code Device
Before programming a device to one of your
HomeLink buttons, you must determine
whether the device has a rolling code or
non-rolling code.
Rolling Code Devices
To determine if your device has a rolling code,
a good indicator is its manufacturing date.
Typically, devices
1995 have rolling codes. A device with a
rolling code will also have a "LEARN" or
"TRAIN" button located where the antenna is
attached to the device. The button may not
be immediately visible when looking at the
light
device. The name and color of the button may
vary slightly by manufacturer.
NOTE:
The "LEARN" or "TRAIN" button is not the
button you normally use to operate the de-
vice.
