System self-check
Initially, after switching on the ignition,
malfunctions 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 to
workshop
appears in the multifunction dis-
play.
Emergency calls
An emergency call is initiated
automatically following an accident in
which the emergency 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 (
୴ page 291) 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
Connecting call
appears in the multifunction display and
the audio system is muted. When the
connection 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.
i
The Tele Aid system utilizes the cellular
network for communication and the
GPS (G
lobal Positioning System) satel-
lites for vehicle location. If either of
these signals is unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.

the Roadside Assistance button and/or in
the Information button remain illuminated
constantly in red and/or message

is displayed in the multifunction
display after the system self-check, a mal-
function in the system has been detected.
If a malfunction is indicated as outlined
above, the system may not operate as
expected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.
