these signals are unavailable, the Tele
Aid system may not function and if this
occurs, assistance must be summoned

Emergency calls
An emergency call is initiated automatical-
ly:
following an accident in which the
emergency tensioning devices (ETDs)
or airbags deploy,
if the anti-theft alarm or the tow-away
alarm stays on for more than
20 seconds. See anti-theft alarm sys-
tem (
page 75) and tow-away alarm
(
page 77).
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 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 multifunc-
tion display. All information relevant to the
emergency, such as the location of the ve-
hicle (determined by the GPS satellite loca-
tion system), vehicle 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 pre-
cisely the nature of the accident provided
they can speak to an occupant of the vehi-
cle.
