The light illuminates when the trunk lid is
opened. When the trunk lid is closed, the
light goes off.
The light will go off af ter a period of time if
the trunk lid is lef t open, unless the ignition
switch is placed in the ON position.
For additional information, refer to “Exterior
and interior lights” in the “Do-it-yourself ”
section of this manual.The HomeLink® Universal Transceiver pro-
vides a convenient way to consolidate the
functions of up to three individual hand-
held transmitters into one built-in device.
HomeLink® Universal Transceiver:
• Will operate most radio frequency de-
vices such as garage doors, gates, home
and office lighting, entry door locks and
security systems.
• Is powered by your vehicle's battery. No separate batteries are required. If the ve-
hicle's battery is discharged or is discon-
nected, HomeLink® will retain all pro-
gramming.
When the HomeLink® Universal Trans-
ceiver is programmed, retain the original
transmitter for future programming pro-
cedures (Example: new vehicle pur-
chases). Upon sale of the vehicle, the
programmed HomeLink® Universal
Transceiver buttons should be erased for
security purposes. For additional infor-
mation, refer to “Programming
HomeLink®” in this section.WARNING
• Your vehicle's engine should be
turned off while programming the
HomeLink® Universal Transceiver. Do
not breathe exhaust gases; they con-
tain colorless and odorless carbon
monoxide. Carbon monoxide is dan-
gerous. It can cause unconscious-
ness or death.
• Do not use the HomeLink® Universal
Transceiver with any garage door
opener that lacks safety stop and re-
verse features as required by federal
safety standards. (These standards
became effective for opener models
manufactured af ter April 1, 1982). A
garage door opener which cannot
detect an object in the path of a clos-
ing garage door and then automati-
cally stop and reverse, does not meet
current federal safety standards. Us-
ing a garage door opener without
these features increases the risk of
serious injury or death.

NOTE:
Some devices may require you to replace
Step 2 with the cycling procedure noted
in “Programming HomeLink® for Cana-
dian customers and gate openers” in this
section.
3. Press and hold the programmedHomeLink® button and observe the indi-
cator light.
• If the indicator light
O1is solid/
continuous, programming is com-
plete and your device should activate
when the HomeLink® button is
pressed and released.
• If the indicator light
O1blinks rapidly
for 2 seconds and then turns to a
solid/continuous light, continue
with Steps 4-6 for a rolling code de-
vice. A second person may make the
following steps easier. Use a ladder or
other device. Do not stand on your ve-
hicle to perform the next steps. 4. At the receiver located on the garage
door opener motor in the garage, locate
the “learn” or “smart” button (the name
and color of the button may vary by
manufacturer but it is usually located
near where the hanging antenna wire is
attached to the unit). If there is difficulty
locating the button, reference the ga-
rage door opener’s manual.
5. Press and release the “learn” or “smart” button.
NOTE:
Once the button is pressed, you have ap-
proximately 30 seconds to initiate the
next step.
6. Return to the vehicle and firmly press and hold the trained HomeLink® button
for 2 seconds and release. Repeat the
“press/hold/release” sequence up to
three times to complete the training
process. HomeLink® should now acti-
vate your rolling code equipped device.
7. If you have any questions or are having difficulty programming your HomeLink®
buttons, refer to the HomeLink® web site
at: www.homelink.com or call
1-800-355-3515.
PROGRAMMING HOMELINK® FOR
CANADIAN CUSTOMERS AND GATE
OPENERS
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
af ter several seconds of transmission –
which may not be long enough for
HomeLink® to pick up the signal during
training. Similar to this Canadian law, some
U.S. gate operators are designed to “tim-
eout” in the same manner.
If you live in Canada or you are having diffi-
culties training a gate operator orgarage
door opener by using the “Training” proce-
dures, replace “Programming HomeLink®”
step 2 with the following:
NOTE:
When programming a garage door
opener, etc., unplug the device during
the “cycling” process to prevent possible
damage to the garage door opener
components.

gramming HomeLink®” step 1 in this
section.
