Programming the HomeLinkž
Transmitter
Do not use the HomeLinkžTransmitter with any garage
door opener that does not have the ªstop and reverseº
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
žTransmitter.
Read the instructions completely before attempting to
program the HomeLink
žTransmitter. Because of
the steps involved, it may be helpful to have another
person available to assist you in programming the
transmitter.
Keep the original transmitter for use in other vehicles as
well as for future HomeLink
žprogramming. It is also
recommended that upon the sale of the vehicle,
the programmed HomeLink
žbuttons should be erased
for security purposes. Refer to ªErasing HomeLinkž
Buttonsº or, for assistance, contact HomeLinkžon 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.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. Press and hold down the two outside buttons,
releasing only when the 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
transmitter to the remaining two HomeLink
žbuttons.
2. Position the end of your hand-held transmitter about
1 to 3 inches (3 to 8 cm) away from the HomeLink
ž
buttons while keeping the indicator light in view.
3. Simultaneously press and hold both the desired
button on HomeLink
žand 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 ªGate Operator and Canadian
Programmingº later in this section.
2-39

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

Passenger's Side Temperature Knob
The passenger's side knob can be used to change the
temperature of the air coming through the system
on the passenger's side of the vehicle. The temperature
can be adjusted even if the system is turned off. This
is possible since outside air will always ¯ow through the
system as the vehicle is moving forward unless it is
set to recirculation mode. See ªRecirculationº later in this
section.
Turn the knob counterclockwise or clockwise to lower or
increase the cabin temperature. The display will show
the temperature setting decreasing or increasing and anarrow pointing to the passenger will be displayed under
and to the right of the temperature setting.
