Section 2 Features and Controls

HomeLink®Transmitter
HomeLink®
If your vehicle has this feature, the control buttons are
located on the driver’s sun visor.
HomeLink
®Wireless Control System provides a way to
replace up to three hand-held radio-frequency (RF)
transmitters used to activate devices such as gate
operators, garage door openers, entry door locks,
security systems, and home lighting. Additional
Homelink
®information can be found on the Internet at
www.homelink.com or by calling 1-800-355-3515.This device complies with Part 15 of the FCC Rules.
Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation.
This device complies with RSS-210 of Industry Canada.
Operation is subject to the following two conditions:
1. This device may not cause interference.
2. This device must accept any interference received,
including interference that may cause undesired
operation of the device.
Changes or modications to this system by other than
an authorized service facility could void authorization to
use this equipment.
Programming the HomeLink®
Do not use HomeLink®with any garage door opener
that does not have the “stop and reverse” feature. This
includes any garage door opener model manufactured
before April 1, 1982. If you have a newer garage
door opener with rolling codes, please be sure to follow
Steps 6 through 8 to complete the programming of
your HomeLink
®Transmitter.
2-36

Read the instructions completely before attempting to
program HomeLink®. Because of the steps involved, it
may be helpful to have another person available to
assist you in the programming steps.
Keep the original hand-held transmitter for use in other
vehicles as well as for future HomeLink
®programming.
It is also recommended that upon the sale of the
vehicle, the programmed HomeLink
®buttons should be
erased for security purposes. See “Erasing HomeLink®
Buttons” later in this section or, for assistance,
contact HomeLink®on the Internet at:
www.homelink.com or by calling 1-800-355-3515.
Be sure that people and objects are clear of the garage
door or gate operator you are programming. When
programming a garage door, it is advised to park outside
of the garage.
It is recommended that a new battery be installed in
your hand-held transmitter for quicker and more
accurate transmission of the radio-frequency signal.
Programming HomeLink®
Your vehicle’s engine should be turned off while
programming HomeLink®. Follow these steps to program
up to three channels:
1. Press and hold down the two outside HomeLink
®
buttons, releasing only when the HomeLink®
indicator light begins to ash, after 20 seconds. Do
not hold down the buttons for longer than
30 seconds and do not repeat this step to program
a second and/or third hand-held transmitter to
the remaining two HomeLink
®buttons.
2. Position the end of your hand-held transmitter
about 1 to 3 inches (3 to 8 cm) away from the
HomeLink
®buttons while keeping the indicator light
in view.
3. Simultaneously press and hold both the desired
HomeLink
®button and the hand-held transmitter
button. Do not release the buttons until Step 4 has
been completed.
Some entry gates and garage door openers may
require you to substitute Step 3 with the procedure
noted in “Gate Operator and Canadian
Programming” later in this section.
2-37

4. The indicator light will ash slowly at rst and then
rapidly after HomeLink®successfully receives the
frequency signal from the hand-held transmitter.
Release both buttons.
5. Press and hold the newly-trained HomeLink
®button
and observe the indicator light.
If the indicator light stays on constantly,
programming is complete and your device should
activate when the HomeLink
®button is pressed and
released.
To program the remaining two HomeLink
®buttons,
begin with Step 2 under “Programming HomeLink®.”
Do not repeat Step 1 as this will erase all of the
programmed channels.
If the indicator light blinks rapidly for two seconds
and then turns to a constant light, continue with
Steps 6 through 8 following to complete the
programming of a rolling-code equipped device,
most commonly, a garage door opener.6. Locate in the garage, the garage door opener
receiver (motor-head unit). Locate the “Learn”
or “Smart” button. This can usually be found where
the hanging antenna wire is attached to the
motor-head unit.
7. Firmly press and release the “Learn” or “Smart”
button. The name and color of the button may
vary by manufacturer.
You will have 30 seconds to start Step 8.
8. Return to the vehicle. Firmly press and hold the
programmed HomeLink
®button for two seconds,
then release. Repeat the press/hold/release
sequence a second time, and depending on the
brand of the garage door opener, or other rolling
code device, repeat this sequence a third time
to complete the programming.
HomeLink
®should now activate your rolling-code
equipped device.
To program the remaining two HomeLink
®buttons,
begin with Step 2 of “Programming HomeLink®.” You do
not want to repeat Step 1, as this will erase all
previous programming from the HomeLink
®buttons.
2-38

Gate Operator and Canadian
Programming
Canadian radio-frequency laws require transmitter
signals to time out or quit after several seconds of
transmission. This may not be long enough for
HomeLink
®to pick up the signal during programming.
Similarly, some U.S. gate operators are manufactured to
time out in the same manner.
If you live in Canada, or you are having difficulty
programming a gate operator or garage door opener by
using the “Programming HomeLink
®” procedures,
regardless of where you live, replace Step 3 under
“Programming HomeLink
®” with the following:
Continue to press and hold the HomeLink
®button while
you press and release every two seconds (cycle) the
hand-held transmitter button until the frequency
signal has been successfully accepted by HomeLink
®.
The HomeLink®indicator light will ash slowly at
rst and then rapidly. Proceed with Step 4 under
“Programming HomeLink
®” to complete.
Using HomeLink®
Press and hold the appropriate HomeLink®button for at
least half of a second. The indicator light will come
on while the signal is being transmitted.
Erasing HomeLink®Buttons
To erase programming from the three HomeLink®
buttons do the following:
1. Press and hold down the two outside buttons until
the indicator light begins to ash, after 20 seconds.
Do not hold the two outside buttons for longer
than 30 seconds.
2. Release both buttons.
HomeLink
®is now in the train (learning) mode and can
be programmed at any time beginning with Step 2
under “Programming HomeLink
®” shown earlier in
this section.
Individual buttons cannot be erased, but they can be
reprogrammed. See “Reprogramming a Single
HomeLink
®Button” following this section.
2-39

Reprogramming a Single HomeLink®
Button
To program a device to HomeLink®using a HomeLink®
button previously trained, follow these steps:
1. Press and hold the desired HomeLink
®button. Do
not release the button.
2. The indicator light will begin to ash after
20 seconds. While still holding the HomeLink
®
button, proceed with Step 2 under “Programming
HomeLink®” shown earlier in this section.
For questions or comments, contact HomeLink
®at
1-800-355-3515, or on the internet at
www.homelink.com.
Storage Areas

To open the glove box, lift up on the lever. The glove
box has a light inside and a shelf for storing manuals.
The shelf is located at the top of the glove box.

If your vehicle has the
ve-passenger console,
there is a cupholder in front
of the center console. The
cupholder has an arm that
adjusts to two positions to
t either a large cup or
two smaller cups.
If your vehicle has the
six-passenger console, a
front console cupholder
