mand)
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
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. To
raise, press button æ and to lower,
press button ç. The volume can also
be adjusted using the volume knob on your
audio system or COMAND* head unit.
To activate, press the SOS button, the
Roadside Assistance button • or
the Information button ¡, depend-
ing on the type of response required. Shortly after the completion of your Tele
Aid acquaintance call, you will receive a
user ID and password. 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 switching on ignition, mal-
functions are detected and indicated (the
indicator lamps in the SOS button, the
Roadside Assistance button
• and the
Information button ¡ stay on longer
than ten seconds or do not come on). The
message
Tele Aid malfunction. Drive

appears for approximately
ten seconds in the multifunction display.
iThe SOS button is located above the in-
side rear view mirror.
The Roadside Assistance button •
and the Information button ¡ are
located below the center armrest
cover.!The Tele Aid system utilizes the cellular
network for communication and the
GPS (Global Positioning System) satel-
lites 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.

Emergency calls
An emergency call is initiated automatical-
ly following an accident in which the emer-
gency tensioning devices (ETDs) or air
bags deploy.
An emergency call can also be initiated
manually by opening the cover next to the
interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (
page 264) for instruc-
tions on initiating an emergency call man-
ually.
Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message
Connecting call
appears in the multifunction display and
the audio system is muted. When the con-
nection is established, the message
Call connected
appears in the multifunc-
tion display. All information relevant to the
emergency, such as the location of the
vehicle (determined by the GPS satellite
location system), vehicle model, identifica-
tion 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 initiat-
ed. The Response Center will attempt to
determine more precisely the nature of the
emergency provided they can speak to an
occupant of the vehicle.
The Tele Aid system is available if:
it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection
and cellular air time
the relevant cellular phone network
and GPS signals are available and pass
the information on to the Response
Center

nearest Mercedes-Benz Center as soon as
possible.
iLocation of the vehicle on a map is only
possible if the vehicle is able to receive
