mand)
The Tele Aid system consists of three
types of response:
automatic and manual emergency
roadside assistance
information.
The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the multifunction steering wheel. To
raise, press buttonæ and to lower,
press buttonç.
To activate, press the SOS button, the
Roadside Assistance button• or
the Information button¡, depend-
ing on the type of response required.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is
covering a distance of 44 feet
(approximately 14 m) every second.
!The initial activation of the Tele Aid sys-
tem may only be performed by com-
pleting the subscriber agreement and
placing an acquaintance call using the
SOS button. Failure to complete either
of these steps will result in a system
that is not activated. If the system is
not activated, the indicator lamp in the
SOS button stays on after switching on
the ignition and the message
Tele Aid
not activated
will appear in the multi-
function display for approximately
ten seconds.
If you have any questions regarding ac-
tivation, please call the Response
Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).

Upgrade Signals
The Tele Aid system processes calls using
the following priority.
Automatic emergency – First priority
Manual emergency – Second priority
Roadside assistance – Third priority
Information – Fourth priority
Should a higher priority call be initiated
while you are connected, an upgrade (al-
ternating) tone will be heard, and the ap-
propriate indicator lamp will flash. If
certain information such as vehicle identi-
fication number or customer information is
not available, the operator may need to re-
transmit.
During this time you will hear a beep and
voice contact will be interrupted. Voice
contact will resume once the retransmis-
sion is completed. Once a call is conclud-
ed, a beep will be heard, and the respective
indicator lamp will stop flashing. The
COMAND system operation will resume. Response Center was established, then
the Tele Aid system could not initiate
an Information call (e.g. the relevant
cellular phone network is not avail-
able). The message
Info Call failed
appears in the multifunction display.
Information calls can be terminated us-
ing the ìbutton on the multifunc-
tion steering wheel.!If the indicator lamps do not start flash-
ing after pressing one of the buttons or
remain illuminated (in red) at any time,
the Tele Aid system has detected a
malfunction or the service is currently
not active, and may not initiate a call.
Visit your Mercedes-Benz Center and
have the system checked or contact
the Response Center at
1-800-756-9018 (in the USA) or
1-888-923-8367 (in Canada) as soon
as possible.

Programming or reprogramming the in-
tegrated remote control
Step 1:
Switch on ignition.
Step 2:
If you have previously programmed an
integrated signal transmitter button
and wish to retain its programming,
proceed to step 3. Otherwise, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when the indicator light be-
gins 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 trans-
mitter to the remaining two signal
transmitter buttons, do not repeat this
step and begin directly with step 3.Step 3:
Hold the end of the hand-held remote
control transmitter6 of the device
you wish to train approximately 2 to
5 in (5 to12 cm) away from the surface
of the integrated remote control locat-
ed on the interior rear view mirror,
keeping the indicator lamp1 in view.
Step 4:
Using both hands, simultaneously
press the hand-held transmitter
button5 and the desired integrated
signal transmitter button (2, 3
or4). Do not release the buttons until
completing step 5.
The indicator lamp1 on the integrat-
ed remote control will flash, first slowly
and then rapidly.Step 5:
When the indicator lamp1 flashes
rapidly, release both buttons.
Step 6:
Press and hold the just-trained inte-
grated signal transmitter button and
observe the indicator lamp1.
If the indicator lamp1 stays on con-
stantly, programming is complete and
your device should activate when the
integrated signal transmitter button is
pressed and released.iThe indicator lamp1 flashes 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 sec-
onds.
