tentionally (e.g. SmartKey inside vehicle),
and the reserve SmartKey is not handy:
Contact the Mercedes-Benz Response

approximately 10 seconds during the system
self-check after switching on the ignition (togeth-
er with the SOS button and the Roadside
Assistance button•).
See system self-check (
page 332) if the indi-
cator lamp does not come on in red or stays on
longer than approximately 10 seconds.
If the indicator lamp in the Information
button¡ is flashing continuously and there
was no voice connection to the Response Center
established, then the Tele Aid system could not
initiate an Information call (e.g. the relevant cel-
lular phone network is not available). The mes-
sage

Information calls can be terminated using
thet button on the multifunction steering
wheel or the END button on the COMAND sys-
tem.
!If the indicator lamps do not start flashing

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.
