Control and operation of radio transmitters
COMAND, radio and telephone
1 Observe all legal requirements.
Telephones and two-way radio
Radio transmitters, such as a portable telephone or a
citizens band unit should only be used inside the
vehicle if they are connected to an antenna that is
installed on the outside of the vehicle.
Refer to the radio transmitter operation instructions
regarding use of an external antenna.
Wa r n i n g !
Please do not forget that your primary
responsibility is to drive the vehicle. Only operate
the COMAND (Cockpit Management and Data
System), radio or telephone
1 if road and traffic
conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is covering
a distance of approximately 50 feet (approximately
14 m ) e v e r y s e c o n d .
Wa r n i n g !
Never operate radio transmitters equipped with a
built-in or attached antenna (i.e. without being
connected to an external antenna) from inside the
vehicle while the engine is running. Doing so could
lead to a malfunction of the vehicle’s electronic
system, possibly resulting in an accident and
personal injury.

Te l e A i d (optional for Canada)
Important!
The initial activation of the Tele Aid system may only be
performed by completing 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 turning electronic key in starter switch to
position 2 and the message “TELE AID – NOT
ACTIVATED” will be shown in the multifunction display
for approx. 10 seconds.
If you have any questions regarding activation, please
call the Response Center at 1-800-756-9018 (in the USA)
or 1-888-923-8367 (in Canada).
(Te l ematic Alarm Identification on Demand)
The Tele Aid system consists of three types of response;
automatic and manual emergency, roadside assistance
and information.
The Tele Aid system is operational providing that the
vehicle’s battery is charged, properly connected, not
damaged and cellular 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, for raising press buttonæ and for
lowering press buttonç.
To activate, press the SOS button, the Roadside
Assistance button• or the Information button¡,
depending on the type of response required.
Shortly after the completion of your Acquaintance Call,
you will receive a user ID and password via first call
mail. By visiting www.mbusa.com and selecting “Tele
Aid” (USA only), you will have access to account
information, remote door unlock, profile and more.
Important!
Tele Aid utilizes the cellular network for
communication and the GPS (Global Positioning
System) satellites for vehicle location. If either of these
signals are unavailable, the Tele Aid system may not
function and if this occurs, assistance must be
summoned by other means.

established, the message “EMERGENCY CALL – 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.
A voice connection between the Response Center and
the occupants of the vehicle will be established
automatically soon after the emergency call has been
initiated. When a voice connection is established the
audio system mutes and the message “TELE AID –
EMERGENCY CALL ACTIVE” appears in the
multifunction display. The Response Center will attempt
to determine more precisely the nature of the accident
provided they can speak to an occupant of the vehicle.
The Tele Aid system is available if:
•it has been activated and is operational. Activation
requires a subscription for monitoring services and
cellular air time,
•the relevant cellular phone network and GPS signals
are available and pass the information on to the
response center.Note:
Location of the vehicle on a map is possible if the
vehicle is able to receive signals from the GPS satellite
network and pass the information on to the response
center.
Wa r n i n g !
If the indicator lamp in the SOS button is
illuminated continuously and there was no voice
connection to the Response Center established,
then the Tele Aid system could not initiate an
emergency call (e.g. the relevant cellular phone
network is not available). The message
“EMERGENCY CALL – CALL FAILED” appears in
the multifunction display for approx. 10 seconds.Should this occur, assistance must be summoned
by other means.

Important!
If the indicator lamps do not start flashing after
pressing one of the buttons or remain illuminated (in

or the service is not currently 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.Upgrade Signals
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 (alternating) tone will be heard,
and the appropriate indicator lamp will flash. If certain
information such as vehicle identification number or
customer information is not available, the operator may
need to retransmit. During this time you will hear a
beep and voice contact will be interrupted. Voice contact
will resume once the retransmission is completed. Once
a call is concluded, a beep will be heard and the
appropriate indicator lamp will stop flashing. The
COMAND system operation will resume (only vehicles
with COMAND).
