Useful features
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 TO WORKSHOP!
appears for approximately ten seconds in
the multifunction display.
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 257) 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 con-
nection is established, the message
CALL
CONNECTED appears in the multifunction
display. All information relevant to the
emergency, such as the location of the ve-
hicle (determined by the GPS satellite loca-
tion system), vehicle model, identification
number and color are generated.
i
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 summoned
by other means.
Warning!
G
If the indicator lamps in the SOS button, in
the Roadside Assistance button and/or in
the Information button do not come on dur-
ing the system self-check, or if any of these
indicators remain illuminated continuously
in red and/or the message
TELE AID MALFUNCTION
DRIVE TO WORKSHOP!
is displayed in the multifunction display af-
ter the system self-check, a malfunction in
the system has been detected.
If a malfunction is indicated as outlined
above, the system may not operate as ex-
pected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.
