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 10 seconds or do not come on). The
message
Tele Aid – Drive to workshop
appears for approximately 10 seconds in
the multifunction display.
Emergency calls
An emergency call is initiated
automatically following an accident in
which the emergency tensioning devices
(ETDs) or airbags have deployed.
An emergency call can also be initiated
manually by opening the cover next to the
inside rear view mirror labeled SOS, then
briefly pressing the button located under
the cover.
For more information, see “Initiating an
emergency call manually” (
୴ page 211).

When a Tele Aid call has been initiated,
the audio system is muted and the se-
lected mode (radio or CD) pauses. The
cellular phone (if installed) switches
off. If you must use this phone, we rec-
ommend that you use it only with the
vehicle at a standstill in a safe location.
Remove the phone from the cradle and
place the call. The multifunction display
in the instrument cluster is available for
use. After the Tele Aid call has ended,
the optional cellular phone switches on
again. A PIN entry might be necessary.
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 -
Drive to workshop
is displayed in the
multifunction display after 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.
