An emergency call is initiated automatical-
ly:

following an accident in which the
emergency tensioning detractors
(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 (

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 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

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. The Response Center
will attempt to determine more precisely
the nature of the accident provided they
can speak to an occupant of the vehicle.

ter or other liquid in this area, the Tele Aid
control unit could suffer an electrical short
circuit making the system inoperative. In
this case the indicator lamp in the SOS but-
ton does not illuminate during or remains il-
luminated after the system self-check. Have

cedes-Benz Center as soon as possible.
