Tele Aid (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).
(Telematic 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, Info Services* profile
and more.

switch 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). The message “TELE AID – VISIT
WORKSHOP” appears for approx. 10 seconds in the
multifunction display.

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 43 and 44.
An emergency call can also be initiated manually by

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. The
message “EMERGENCY CALL – CONNECTING CALL”

connection is 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.
