Garage door opener
The integrated remote control is capable of
operating up to three separately controlled
devices. It provides a convenient way to re-
place up to three hand-held remote con-
trols used to operate devices such as
garage door openers, gate openers, or oth-
er devices compatible with HomeLink
® or
some other systems.
Before the integrated remote control can
be used, it must be programmed to the ga-
rage door opener, gate operator or other
device you wish to operate. See the follow-
ing instructions for programming informa-
tion.iThe remote door unlock feature is available
if the relevant cellular phone network is avail-
able.

Step 1:
Switch on the ignition (page 42).
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,
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 exhaust gas contains carbon monoxide
(CO), and inhaling it can cause unconscious-
ness and possible death.

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 be-
gin directly with step 3.Step 3:Hold end of the hand-held remote
control5 of the device you wish to
train approximately 2 to 5 in
(5 to 12 cm) away from the signal
transmitter button (2, 3 or4) to be
programmed, while keeping the indica-
tor 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 com-
pleted.
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 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.
iIndicator lamp1 flashes immediately the
first time the signal transmitter button is
programmed. 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.

Step 4:
Press and hold the signal transmitter
button (2, 3 or4). Do not release
this button until it has been successful-
ly 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,
indicator lamp1 will flash slowly and
then rapidly after several seconds.
Proceed with programming step 5 and
step 6 to complete.Reprogramming a single signal trans-
mitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:
Switch on the ignition (page 42).
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 42).
Select and press the appropriate inte-
grated signal transmitter button (2,
3 or4) to activate the remote con-
trolled 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 42).
Simultaneously press and hold outer
signal transmitter buttons2 and4,
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.
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.

Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:

Check the frequency of 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.

If another hand-held remote control is
available for the same device, try the
programming steps again using that
other hand-held remote control. Make
sure new batteries are in the hand-held
remote control before beginning the
procedure.

Straighten the antenna wire from the
garage door opener assembly. This
may help improve transmitting and/or
receiving signals.
iCertain types of garage door openers are in-
compatible with the integrated remote control. If
you should experience further difficulties with
programming the integrated remote control,
contact an authorized Mercedes-Benz Light
Truck Center, or call Mercedes-Benz Customer
Assistance Center (in the USA only) at
1-800-FOR-MERCedes, or Customer Service (in
Canada) at 1-800-387-0100.
