Safety Latch Location

To Close The Hood

Lower the hood to approximately 12 inches (30 cm)

GARAGE DOOR OPENER — IF EQUIPPED
HomeLink® replaces up to three hand-held
transmitters that operate devices such as
garage door openers, motorized gates, lighting
or home security systems. The HomeLink® unit
is powered by your vehicle’s 12 Volt battery.
The HomeLink® buttons that are located on the
sun visor designate the three different Home -
Link® channels.

HomeLink® Buttons
NOTE:
HomeLink® is disabled when the Vehicle Secu
-
rity Alarm is active.
WARNING!
Be sure the hood is fully latched before
driving your vehicle. If the hood is not fully
latched, it could open when the vehicle is in
motion and block your vision. Failure to follow
this warning could result in serious injury or
death.
CAUTION!
To prevent possible damage, do not slam the
hood to close it. Use a firm downward push at
the front center of the hood to ensure that
both latches engage.
WARNING!
Your motorized door or gate will open and
close while you are programming the
universal transceiver. Do not program the
transceiver if people, pets or other objects
are in the path of the door or gate. Only use
this transceiver with a garage door opener
that has a “stop and reverse” feature as
required by Federal safety standards. This
includes most garage door opener models
manufactured after 1982. Do not use a
garage door opener without these safety
features.
Vehicle exhaust contains carbon monoxide,
a dangerous gas. Do not run your vehicle in
the garage while programming the trans -
ceiver. Exhaust gas can cause serious
injury or death.

tance.
Before You Begin Programming HomeLink®
Be sure that your vehicle is parked outside of
the garage before you begin programming.
For more 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.
To erase the channels, place the ignition in the
ON/RUN position, and push and hold the two
outside HomeLink® buttons (I and III) for up to
20 seconds or until the orange indicator
flashes. NOTE:
Erasing all channels should only be
performed when programming HomeLink®
for the first time. Do not erase channels when
programming additional buttons.
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 infor-
mation or assistance.

It is NOT the button that is normally used to
open and close the door. The name and color of
the button may vary by manufacturer.
Training The Garage Door Opener

1. Place the ignition in the ON/RUN position.

To reprogram a channel that has been previ -
ously trained, follow these steps:

1. Place the ignition in the ON/RUN position.

2. Push and hold the desired HomeLink® button until the indicator light begins to
flash after 20 seconds. Do not release the
button.
3. Without releasing the button proceed with “Programming A Rolling Code” step 2 and
follow all remaining steps.

light changes from slow to rapid.
5. Press and hold the programmed Home -
Link® button and observe the indicator
light.
If the indicator light stays on constantly,
