interior rear view mirror labeled SOS, then
briefly pressing the button located under
the cover. See (

tions on initiating an emergency call man-
ually.

indicator lamp in the SOS button will begin
to flash. The message
Connecting call
appears in the multifunction display and
the audio system is muted. When the con-
nection is established, the message

tion display. All information relevant to the
emergency, such as the location of the ve-

lites for vehicle location. If either of
these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.
