The HomeLink
®Universal
Transceiver built into your vehicle can
be programmed to operate up to three
remote controlled devices around
your home, such as garage doors,
lighting, or home security systems.
General Safety InformationBefore programming your HomeLink
to operate a garage door opener,
confirm that the opener has an
external entrapment protection
system, such as an‘‘electronic eye,’’or
other safety and reverse stop features.
If your garage door was manufactured
before April 1, 1982, you may not be
able to program HomeLink to operate
it. These units do not have safety
features that cause the motor to stop
and reverse it if an obstacle is
detected during closing, increasing
the risk of injury. Do not use
HomeLink with any garage door
opener that lacks safety stop and
reverse features.Units manufactured between April 1,
1982 and January 1, 1993 may be
equipped with safety stop and reverse
features. If your unit does not have an
external entrapment protection
system, an easy test to confirm the
function and performance of the safety
stop and reverse feature is to lay a 2
╳4 under the closing door. The door
should stop and reverse upon
contacting the piece of wood.
As an additional safety feature, garage
door openers manufactured after
January 1, 1993 are required to have
external entrapment protection
systems, such as an electronic eye,
which detect an object obstructing the
door.
Important Safety PrecautionsRefer to the safety information that came
with your garage door opener to test that
the safety features are functioning
properly. If you do not have this
information, contact the manufacturer of
the equipment.
Before programming HomeLink to a
garage door or gate opener, make sure
that people and objects are out of the way
of the device to prevent potential injury or
damage.
When programming a garage door opener,
park just outside the garage.Training HomeLinkBefore you begin
－If you just
received your vehicle and have not
trained any of the buttons in
HomeLink before, you should erase
any previously learned codes before
training the first button.
To do this, press and hold the two
outside buttons on the HomeLink
transceiver for about 20 seconds,
until the red indicator flashes.
Release the buttons, then proceed to
step 1.
