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.
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 and properly connected, not
damaged and cellular and GPS coverage is available. 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 and more.
System self-check
Initially, after turning the key in steering lock to
position 2, 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).
Important!
Always make sure that the indicator lamps in the
“SOS” button, in the “Roadside Assistance” button and
in the “Information” button do not remain illuminated
constantly in red after the system self check.
If a malfunction is indicated as outlined above, have the
system checked at the nearest Mercedes-Benz Center as
soon as possible.

Te ch n i c a l

and controlsOperationDrivingInstrument
cluster displayPractical hints Car care Index Emergency calls
An emergency call is initiated automatically:
•following an accident in which the Emergency
Tensioning Retractors (ETR’s) or airbags deploy,
•if the antitheft alarm or the tow away alarm stays on
for more than 20 seconds, see pages 35 and 37.
An emergency call can also be initiated manually by
opening the cover next to the inside rear view mirror
labeled “SOS”, then briefly pressing the button located
under the cover. See below for instructions on initiating
an emergency call manually.
Once the emergency call is in progress, the indicator
lamp in the “SOS” button will begin to flash. 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. 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).Should this occur, assistance must be summoned
by other means.
