Emergency calls
An emergency call is initiated automatical-
ly:
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 sys-
tem (
page 78)and tow-away alarm
(
page 79).
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. See below for instructions on
initiating an emergency call manually.
Once the emergency call is in progress, the
indicator lamp in the “SOS” button will be-
gin to flash. The message
EMERGENCY CALL
– CONNECTING CALL
appears in the multi-
function display. When the connection is
established, the message
EMERGENCY CALL
– CALL CONNECTED
appears in the multi-
function display. All information relevant to
the emergency, such as the location of the
vehicle (determined by the GPS satellite lo-
cation system), vehicle model, identifica-
tion 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
ap-
pears in the multifunction display. The Re-
sponse 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 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.
