Emergency calls
G
An emergency call is initiated automatical-
ly following an accident in which the emer-
gency tensioning devices (ETDs) or
air bags deploy.
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 264) for instruc-
tions on initiating an emergency call man-
ually.
Once the emergency call is in progress, the
indicator lamp in the SOS button will begin
to flash. The message
appears in the multifunction display and
the audio system is muted. When the con-
nection is established, the message
appears in the multifunc-
Call connected
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.
