System self-check
Initially, after switching on the ignition,
malfunctions are detected and indicated
(the indicator lamps in the SOS button, the
Roadside Assistance button• and the
Information button ¡ stay on longer
than 10 seconds or do not come on). The
message
Tele Aid inoperative appears
in the multifunction display. Emergency calls
An emergency call is initiated auto-
matically following an accident in which
the emergency tensioning devices (ETDs)
or air bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 231) for
instructions on initiating an emergency call
manually.
Once the emergency call is in progress, the
indicator lamp on the SOS button will
begin to flash. The message
Connecting
call
appears in the multifunction display.
When the connection is established, the
message
Call connected appears in the
multifunction display. All information
relevant to the emergency, such as the
location of the vehicle (determined by the
GPS satellite location system), vehicle
model, identification number and color are
generated.
iWhen a Tele Aid call has been initiated,
the COMAND system audio is muted and the
selected mode (radio, CD etc.) pauses.
The optional cellular phone (if installed) inserted
in cradle switches off. If you must use this
phone, we recommend that you use it only with
the vehicle at a standstill in a safe location.
Remove the phone from the cradle and place the
call. The navigation system (if engaged) will con-
tinue to run. The display in the instrument cluster
is available for use, and spoken commands are
only available by pressing the RPT button on the
COMAND system. A pop-up window will appear
in the COMAND system display to indicate that a
Tele Aid call is in progress. After the Tele Aid call
has ended, the optional cellular phone inserted
in the cradle switches on again. A PIN entry
might be necessary.
Warning!G
If the indicator lamps on the SOS button, on
the Roadside Assistance button, and/or on
the Information button remain illuminated
continuously in red and/or the message
Tele Aid inoperative is displayed in the
multifunction display after the system
self-check, a malfunctio n in the system has
been detected.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Light Truck Center
as soon as possible.

Garage door opener
The integrated remote control is capable of
operating up to three separately controlled
devices. It provides a convenient way to
replace up to three hand-held remote
controls used to operate devices such as
garage door openers, gate openers, or
other devices compatible with HomeLink
®
or some other systems.
Before the integrated remote control can
be used, it must be programmed to the
garage door opener, ga te 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 available.
The SOS button will flash and the message
Connecting call will appear in the multi-
function display to indicate receipt of the door
unlock command.

Step 1:
Switch on the ignition (page 39).
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 th
e device to prevent
potential harm or damage. When program-
ming a garage door opener, the door moves
up or down. When programming a gate oper-
ator, 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 co ntrol. 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 outer signal transmitter
buttons2 and 4 and release them
only when indicator lamp 1 begins to
flash after approximately 20 seconds
(do not hold the button for longer than
30 seconds). This procedure 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. Step 3:Hold end of hand-held remote
control
5 of the device you wish to
train approximately 2 to 5 in
(5 to12 cm) away from signal trans-
mitter button ( 2, 3 or 4) to be
programmed, while keeping indicator
lamp 1 in view.
Step 4:
Using both hands, simultaneously
press hand-held remote control
button 6 and the desired signal
transmitter button ( 2, 3 , or 4). Do
not release the buttons until step 5 is
completed.
Indicator lamp 1 will flash, first slowly
and then rapidly. Step 5:
After indicator lamp
1 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 , or 4) and
observe indicator lamp 1.
If indicator lamp 1 stays on
constantly, programming is complete
and your device should activate when
the respective signal transmitter
button ( 2, 3 , or 4) is pressed and
released.
Step 7:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.
iIndicator lamp 1 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 lamp 1 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
garage door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the
following steps.
Step 10:
Return to the vehicle and firmly press,
hold for 2 seconds and release the
programmed signal transmitter button
( 2 ,3 ,or 4).
Step 11:
Press, hold for 2 seconds and release
same signal transmitter button a
second time to complete the training
process. Step 12:
Confirm the garage door operation by
pressing the programmed signal
transmitter button (
2,3 ,or 4).
Step 13:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with step 3.
Gate operator/Can adian 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.
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.
