The Tele Aid system
(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 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 using the volume control on
the MCS unit.
To activate, press the SOS button, the
Roadside Assistance button • or
the Information button ¡ , depend-
ing on the type of response required.

The SOS button, the Roadside Assis-
tance button • and the Information
button ¡ are located in the over-
head control panel.
Shortly after the completion of your ac-
quaintance 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.

The Tele Aid system utilizes the cellu-
lar 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 sum-
moned by other means.
