Emergency calls
An emergency call is initiated
automatically:
ț following an accident in which the
emergency tensioning devices (ETDs)
or airbags deploy.
ț if the anti-theft alarm or the tow-away
alarm stays on for more than
20 seconds. See anti-theft alarm
system (
page 80) and tow-away
alarm (
page 81).
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 225) 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
EMERGENCY CALL –
CONNECTING CALL
appears in the multifunc-
tion display. When the connection is estab-
lished, the message
EMERGENCY CALL – 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.
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 multifunction display. The
Response Center will attempt to determine
more precisely the nature of the accident
provided they can speak to an occupant of
the vehicle.
The Tele Aid system is available if:
ț it has been activated and is
operational. 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
center
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
response center.
