21_DT_OM_EN_USC_t.book Page 49

50GETTING TO KNOW YOUR VEHICLE
Rolling Code Devices
To determine if your device has a rolling code, a
good indicator is its manufacturing date.
Typically, devices manufactured after 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 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 device.
Non-rolling Code Devices
Most devices manufactured before 1995 will
not have a rolling code. These devices will also
not have a “LEARN” or “TRAIN” button.
PROGRAMMING HOMELINK® TO A
G
ARAGE DOOR OPENER
To program any of the HomeLink® buttons to
activate your garage door opener motor, follow
the steps below: NOTE:
All HomeLink® buttons are programmed using
this procedure. You do not need to erase all
channels when programming additional
buttons.

1. Place the ignition switch into the ON/RUN
position.

2. Place the garage door opener transmitter 1 to 3 inches (3 to 8 cm) away from the
HomeLink® button you wish to program,
while keeping the HomeLink® indicator
light in view.

ISCELLANEOUS DEVICE
The procedure on how to program HomeLink®
to a miscellaneous device follows the same
procedure as programming to a garage door
opener Úpage 50. Be sure to determine if the
device has a rolling code, or non-rolling code
before beginning the programming process.
NOTE:
Canadian radio frequency laws require trans -
mitter signals to time-out (or quit) after several
seconds of transmission, which may not be long
enough for HomeLink® to pick up the signal
during programming. Similar to this Canadian
law, some U.S. gate operators are designed to
time-out in the same manner. The procedure
may need to be performed multiple times to
successfully pair the device to your HomeLink®
buttons.
REPROGRAMMING A SINGLE
H
OMELINK® BUTTON
To reprogram a single HomeLink® button that
has been previously trained, without erasing all
the channels, follow the procedure below. Be
sure to determine whether the new device you want to program the HomeLink® button to has
a Rolling Code, or Non-rolling Code.

1. Place the ignition in the ON/RUN position,
without starting the engine.

2. Push and hold the desired HomeLink® button until the HomeLink® Indicator light
begins to flash after 20 seconds. Do not
release the button.
3. Without releasing the button , proceed with
Step 2 in “Programming HomeLink® To A
Garage Door Opener” Ú page 50, and
follow all remaining steps.
CANADIAN/GATE OPERATOR
P
ROGRAMMING
For programming transmitters in Canada/
United States that require the transmitter
signals to “time-out” after several seconds of
transmission.
Canadian radio frequency laws require
transmitter signals to time-out (or quit) after
several seconds of transmission – which may
not be long enough for HomeLink to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators are
designed to time-out in the same manner.
WARNING!
Your motorized door or gate will open and
close while you are programming the
universal transceiver. Do not program the
transceiver if people or pets are in the path
of the door or gate.
Do not run your vehicle in a closed garage
or confined area while programming the
transceiver. Exhaust gas from your vehicle
contains Carbon Monoxide (CO) which is
odorless and colorless. Carbon Monoxide is
poisonous when inhaled and can cause you
and others to be severely injured or killed.
