Programming the integrated remote
control
Step 1:
Switch on the ignition (page 40).Step 2:
If you have previously programmed a
signal transmitter button and wish to
retain its programming, proceed to
step 3.
If you are programming the integrated
remote control for the first time, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when indicator lamp1
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory.
If you later wish to program a second
and/or third hand-held transmitter to
the remaining two signal transmitter
buttons, do not repeat this step and
begin directly with step 3.Warning!G
Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent po-
tential harm or damage. When programming
a garage door opener, the door moves up or
down. When programming a gate operator,
the gate opens or closes.
Do not use the integrated remote control
with any garage door opener that lacks
safety stop and reverse features as required
by U.S. federal safety standards (this
includes any garage door opener model
manufactured before April 1, 1982).
A garage door that cannot detect an object
- signaling the door to stop and reverse -
does not meet current U.S. federal safety
standards.
When programming a garage door opener, it
is advised to park the vehicle outside the
garage.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
gas contains carbon monoxide (CO), and in-
haling it can cause unconsciousness and
possible death.

mitter button (2, 3 or4) to be
programmed, while keeping indicator
lamp1 in view.
Step 4:
Using both hands, simultaneously
press hand-held remote control
button6 and the desired signal trans-
mitter button (2, 3 or4). Do not
release the buttons until step 5 is
completed.
Indicator lamp1 will flash, first slowly
and then rapidly.Step 5:
After indicator lamp1 changes from a
slow to a rapidly flashing light, release
the hand-held remote control button
and the signal transmitter button.
Step 6:
Press and hold the just-trained signal
transmitter button (2, 3 or4) and
observe indicator lamp1.
If the indicator lamp1 stays on
constantly, programming is complete
and your device should activate when
the respective signal transmitter
button (2, 3 or4) is pressed and
released.
Step 7:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.Rolling code programming
To train a garage door opener (or other
rolling code devices) with the rolling code
feature, follow these instructions after
completing the “Programming” portion
(steps 1 through 6) of this text. (A second
person may make the following training
procedures quicker and easier.)
Step 8:
Locate “training” button on the garage
door opener motor head unit.
Exact location and color of the button
may vary by garage door opener brand.
Depending on manufacturer, the
“training” button may also be referred
to as “learn”or “smart” button. If there
is difficulty locating the transmitting
button, refer to the garage door opener
Operator’s Manual.
iIndicator lamp1 flashes immediately the
first time the signal transmitter button is pro-
grammed. If this button has already been
programmed, the indicator lamp will only start
flashing after 20 seconds.
iIf indicator lamp1 flashes rapidly for about
2 seconds and then turns to a constant light,
continue with programming steps 8 through 12
as your garage door opener may be equipped
with the “rolling code” feature.

Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the
integrated signal transmitter 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.
If you live in Canada or if you are having
difficulties programming a gate operator
(regardless of where you live) by using the
programming procedures, replace step 4
with the following:Step 4:
Press and hold the signal transmitter
button (2, 3 or4). Do not release
this button until it has been success-
fully trained.
While still holding down the signal
transmitter button (2, 3 or4),
“cycle” your hand-held remote control
button6 as follows: Press and hold
button6 for 2 seconds, then release
it for 2 seconds, and again press and
hold it for 2 seconds. Repeat this se-
quence on the hand-held remote con-
trol until the frequency signal has been
learned. Upon successful training, indi-
cator lamp1 will flash slowly and then
rapidly after several seconds.
Proceed with programming step 5 and
step 6 to complete.
iSome garage door openers (or other rolling
code equipped devices) may require you to
press, hold for 2 seconds and release the same
signal transmitter button a third time to
complete the training process.

Reprogramming a single signal
transmitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:
Switch on the ignition (page 40).
Press and hold the desired signal
transmitter button (2, 3 or4).
Do not release the button.
Indicator lamp1 will begin to flash af-
ter 20 seconds. Without releasing the
signal transmitter button, proceed with
programming starting with step 3.Operation of integrated remote control
Switch on the ignition (page 40).
Select and press the appropriate inte-
grated signal transmitter button (2,
3 or4) to activate the remote
controlled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.
Erasing the integrated remote control
memory
Switch on the ignition (page 40).
Simultaneously press and hold outer
signal transmitter buttons2 and 4,
for approximately 20 seconds, until
indicator lamp1 flashes rapidly. Do
not hold for longer than 30 seconds.
The codes of all three channels are
erased.Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:

Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 280-390 MHz.

Put a new battery in hand-held remote
control5. This will increase the likeli-
hood of the hand-held remote control
sending a faster and more accurate sig-
nal to the integrated remote control.

While performing step 3, hold
hand-held remote control5 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying
angles at the distance of 2 to 5 in
(5 to 12 cm) away or the same angle at
varying distances.
iUpon completion of programming the inte-
grated remote control, make sure you retain the
hand-held remote control that came with the ga-
rage door opener, gate operator or other device.
You may need it for use in other vehicles, for fu-
ture programming of an integrated remote con-
trol, or simply for continued use as a hand-held
remote control to operate the respective device
in other situations.
iIf you sell your vehicle, erase the codes of all
three channels.
