automatically

following an accident in which the
emergency tensioning devices (ETDs)
or airbags deploy


if the anti-theft alarm or the tow-away

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

tion display. When the connection is estab-
lished, the message

emergency, such as the location of the ve-
hicle (determined by the GPS satellite loca-
tion system), vehicle model, identification

Center and the occupants of the vehicle
will be established automatically soon af-
ter the emergency call has been initiated.
