Useful features
Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message
EMERGENCY CALL –
CONNECTING CALL
appears in the MCS dis-
play. When the connection is established,
the message
EMERGENCY CALL –
CALL CONNECTED
appears in the MCS dis-
play. All information relevant to the emer-
gency, such as the location of the vehicle
(determined by the GPS satellite location
system), vehicle model, identification num-
ber and color are generated.
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.
When a voice connection is established,
the audio system mutes and the message
TELE AID – EMERGENCY CALL ACTIVE
appears in the MCS display. The Response
Center will attempt to determine more pre-
cisely the nature of the accident provided
they can speak to an occupant of the vehi-
cle.
The Tele Aid system is available if:
ț it has been activated and is operation-
al. Activation requires a subscription
for monitoring services, connection
and cellular air time.
ț the relevant cellular phone network
and GPS signals are available and pass
the information on to the response cen-
ter.
i
Location of the vehicle on a map is only
possible if the vehicle is able to receive
signals from the GPS satellite network
and pass the information on to the re-
sponse center.
Warning! G
If the indicator lamp in the SOS button is
illuminated 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 cellular phone network is not available).
The message
EMERGENCY CALL –
CALL FAILED
appears in the MCS display
for approx. ten seconds.
Should this occur, assistance must be sum-
moned by other means.
