UNIVERSAL GARAGE DOOR OPENER
(HOMELINK®)

HomeLink® Buttons And Indicator Light

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 in the
overhead console or sunvisor designate the
three different HomeLink® channels.
To operate HomeLink®, push and release any
of the programmed HomeLink® buttons. These
buttons will activate the devices they are
programmed to with each press of the corre
-
sponding HomeLink® button.
The HomeLink® indicator light is located above
the center button.
BEFORE YOU BEGIN PROGRAMMING
H
OMELINK®
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 transmitter is programmed to
activate the device you are trying to program your
HomeLink® button to.
Ensure that your vehicle is parked outside of the
g a

rage before you begin programming.
It is recommended that you erase all the channels
of
your HomeLink® before you use it for the first
time.
ERASING ALL THE HOMELINK®
C
HANNELS
To erase the channels, follow this procedure:

1. P lace the ignition switch into the ON/RUN
p
osition.

2. Push and hold the two outside HomeLink® b
uttons (I and III) for up to 20 seconds, or until
the HomeLink® indicator light flashes.
NOTE:
Erasing all channels should only be performed
w h
en programming HomeLink® for the first time.
Do not erase channels when programming addi -
tional buttons.
IDENTIFYING WHETHER YOU HAVE A
R
OLLING CODE OR NON-ROLLING CODE
D
EVICE
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
g ood

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
y ou
normally use to operate the device.
Non-rolling Code Devices
Most devices manufactured before 1995 will not
h a

ve a rolling code. These devices will also not
have a “LEARN” or “TRAIN” button.

GETTING TO KNOW YOUR VEHICLE 39
NOTE:
Canadian radio frequency laws require transmitter
s i
gnals 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,
w
ithout starting the engine.

2. Push and hold the desired HomeLink® button u
ntil 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
G a
rage Door Opener” 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 (RF) laws require
t r

ansmitter 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 US gate operators are
designed to time-out in the same manner.
It may be helpful to unplug the device during the
c y

cling process to prevent possible overheating of
the garage door or gate motor.

1. P lace the ignition in the ON/RUN position.

2
. P lace the hand-held 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.

3. Continue to press and hold the HomeLink® bu
tton, while you press and release (cycle) your
hand-held transmitter every two seconds until
HomeLink® has successfully accepted the
frequency signal. The indicator light will flash
slowly and then rapidly when fully trained.

4. Watch for the HomeLink® indicator to change f
lash rates. When it changes, it is programmed. It may take up to 30 seconds or
longer in rare cases. The garage door may
open and close while you are programming.
5. P ress and hold the programmed HomeLink®
b
utton and observe the indicator light.
NOTE:
If the indicator light stays on constantly,
programming is complete and the garage
door/device should activate when the
HomeLink® button is pressed.

To program the two remaining HomeLink®
buttons, repeat each step for each remaining
button. DO NOT erase the channels.

If you unplugged the garage door opener/device
f or

programming, plug it back in at this time.
Reprogramming A Single HomeLink® Button
(C
anadian/Gate Operator)
To reprogram a channel that has been previously
tr
ained, follow these steps:

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

2
. P ress and hold the desired HomeLink® button
u
ntil the indicator light begins to flash after 20
seconds. Do not release the button.
3. W ithout releasing the button, proceed with
“
Canadian/Gate Operator Programming”
step 2 and follow all remaining steps
Ú page 254.

The Rain Sensing system has protection features
for the wiper blades and arms, and will not operate
under the following conditions:
Low Ambient Temperature — When the ignition
is first placed in the ON position, the Rain
Sensing system will not operate until the wiper
switch is moved, vehicle speed is greater than
3 mph (5 km/h), or the outside temperature is
gr

eater than 32°F (0°C).
Transmission In NEUTRAL Position — When the
ignition is ON, and the automatic transmission
is in the NEUTRAL position, the Rain Sensing
system will not operate until the wiper switch is
moved, vehicle speed is greater than 3 mph
(5

km/h), or the gear selector is moved out of
t h
e NEUTRAL position.
Remote Start Mode Inhibit — On vehicles
equipped with a Remote Start system, Rain
Sensing wipers are not operational when the
vehicle is in Remote Start mode.

activate the cupholder. Push the symbol a second
time to turn off the cupholder.
POWER SUNSHADE — IF EQUIPPED
Your vehicle may be equipped with a power
sunshade that will reduce the amount of sunlight
that will shine through the rear windshield.
The power sunshade can be operated using the
U c

onnect system Ú page 122.
Press the “Controls” button and then press the

POWER OUTLETS
Your vehicle is equipped with one 12 Volt (13 Amp)
power outlet on the instrument panel and one
12 Volt (13 Amp) power outlet in the center
c on

sole that can be used to power cellular phones,
small electronics and other low powered electrical
accessories. The power outlets are labeled with
either a “key” or a “battery” symbol to indicate how
the outlet is powered. Power outlets labeled with a
“key” are powered when the ignition switch is in
the ACC or ON/RUN position, while the outlets
labeled with a “battery” are connected directly to
the battery and powered at all times.
WARNING!
When using the cupholder in the “Hot” position,
avoid contact with the heated portion of the
cupholder in order to reduce the possibility of
burns. Persons who are unable to feel pain to
the skin because of advanced age, chronic
illness, diabetes, spinal cord injuries,
medication, alcohol use, exhaustion or other
physical condition must exercise particular care
in order to prevent serious burn injury. Keep the
cupholder free of debris or stray objects when
operated in the “Hot” position.
