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 10 seconds or do not come on). The
message
Malfunction Service Required
appears in the multifunction display.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 258) for
instructions on initiating an emergency call
manually.
Once the emergency call is in progress, the
indicator lamp on the SOS button will
begin to flash. The message
Connecting Call
appears in the multi-
function display. When the connection is
established, the message
Call Connected
appears in the multifunction display. All in-
formation relevant to the emergency, such
as the location of the vehicle (determined
by the GPS satellite location system), vehi-
cle model, identification number and color
are generated.
!The Tele Aid system utilizes the cellular net-
work for communication and the GPS (G
lobal Po-
sitioning S
ystem) satellites for vehicle location. If
either of these signals are unavailable, the
Tele Aid system may not function and if this oc-
curs, assistance must be summoned by other
means.
iWhen a Tele Aid call has been initiated, the
COMAND System audio is muted and the select-
ed mode (radio, tape or CD) pauses. The optional
cellular phone (if installed) and inserted in cradle
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 naviga-
tion* system (if engaged) will continue to run.
The multifunction display in the instrument clus-
ter is available for use, and spoken commands
are only available by pressing the RPT button on
the COMAND System. A pop-up window will ap-
pear in the COMAND System display to indicate
that a Tele Aid call is in progress. After the Tele
Aid call has ended, the optional cellular phone
switches on again. A PIN entry might be neces-
sary.
Warning!G
If the indicator lamps on the SOS button, on
the Roadside Assistance button, and/or on
the Information button remain illuminated
continuously in red and/or the message
Malfunction Service Required 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
expected. Have the system checked at the
nearest Mercedes-Benz Center as soon as
possible.
