Useful features
All information relevant to the emergency,
such as the location of the vehicle (deter-
mined by the GPS satellite location sys-
tem), vehicle model, identification number
and color are generated.
i
During the emergency call message "Emer-
gency Call Activated" is displayed, operation
from COMAND is not possible. The automatic cli-
mate control can be still adjusted using the
switches on the climate control panel.
A voice connection between the Response
Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
The Response Center will attempt to deter-
mine more precisely the nature of the acci-
dent provided they can speak to an
occupant of the vehicle.
i
If no vehicle occupant responds, an ambu-
lance will be sent to the vehicle immediately.

sible if the vehicle is able to receive signals from
the GPS satellite network and pass the informa-
tion on to the Response Center.
Warning!
If the indicator lamp in the SOS button is
flashing continuously and there was no
voice connection to the Response Center
established, then the Tele Aid system could
not initiate an emergency call (e.g. the rele-
vant mobile phone network is not available).
The message:
"Call failed" appears in the multifunction
display for approximately 10 seconds.
A pop-up window with the message:
"Call could not be connected! Please dial

play. Confirm the message pressing

moned by other means.
