using thet button on the multi-
function steering wheel or the END But-
ton on the Modular COMAND System.
!If the indicator lamps do not start flash-
ing after pressing one of the buttons or

Programming the integrated remote
control
Step 1:
Switch on the ignition (
page 38).Step 2:

If you have previously programmed an
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 the 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 be-
gin 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 outside the garage.
Do not run the engine while programming
the integrated remote control. Inhalation of
exhaust gas is hazardous to your health. All
exhaust gas contains carbon monoxide, and
inhaling it can cause unconsciousness and
possible death.


322 Controls in detailUseful featuresStep 3:
Hold the end of the hand-held remote
control5 of the device you wish to
train approximately 2 to 5 in
(5 to12 cm) away from the signal trans-
mitter button (2, 3 or4) to be pro-
grammed, while keeping the indicator
lamp1 in view.
Step 4:

Using both hands, simultaneously
press the hand-held remote control
button6 and the desired signal trans-
mitter button (2, 3 or4). Do not
release the buttons until step 5 is com-
pleted.
The indicator lamp1 will flash, first
slowly and then rapidly.Step 5:

After the indicator lamp1 changes
from a slow to a rapidly flashing light,
release the hand-held remote control
button and the signal transmitter but-
ton.
Step 6:

Press and hold the just-trained signal
transmitter button (2, 3 or4) and
observe the 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 re-
leased.
Step 7:

To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.
iThe indicator lamp1 flashes immedi-
ately the first time the signal transmit-
ter button is programmed. If this button
has already been programmed, the in-
dicator lamp will only start flashing af-
ter 20 seconds.
iIf the 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.

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. Step 9:

Press the “training” button on the ga-
rage door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the follow-
ing two steps.
Step 10:

Return to the vehicle and firmly press,
hold for 2 seconds and release the pro-
grammed signal transmitter button
(2, 3 or4).
Step 11:

Press, hold for 2 seconds and release
same signal transmitter button a sec-
ond time to complete the training pro-
cess.Step 12:

Confirm the garage door operation by
pressing the programmed signal trans-
mitter button (2, 3 or4).
Step 13:

To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.iSome garage door openers (or other
rolling code equipped devices) may
require you to press, hold for 2 seconds
and release the same signal transmit-
ter button a third time to complete the
training process.
