the emergency call and faster transfer of the
accident data.
Measures for rescue, recovery or towing away
can then be initiated in quickly.
With a Mercedes-Benz emergency call, the
R
accident data is only transferred to the public
coordination centre with the approval of the
customer.
In the event of an automatically triggered
emergency call in which there is no voice con-
tact, the accident data is transmitted immedi-
ately to the public emergency call centre.
If the Mercedes-Benz emergency call centre is
R
not available, the 112 emergency call is car-
ried out automatically.
Overview of emergency call systems
Both the Mercedes-Benz emergency call system
as well as the 112 emergency call system (EU
eCall) can help to reduce the time between an
accident and the arrival of emergency services at
the site of the accident. They help locate an acci-
dent site in places that are difficult to access.
Both emergency call systems can initiate an emer-
gency call automatically ( page 369) or man-
/
ually ( page 370).
/
Only make emergency calls if you or others are in
need of rescue. Do not make an emergency call in
the event of a breakdown or a similar situation.
Indicators in the displays
The following messages appear on the central dis-
play or the media display of both emergency call
systems:
SOS NOT READY: the vehicle is not switched

on or the emergency call system is malfunc-
tioning. This does not necessarily indicate
complete failure of the emergency call system.
Emergency calls can still be transmitted.
The display only refers to the vehicle and does
not take account of the availability of mobile
phone networks and the Mercedes-Benz emer-
gency call centre.
The functional readiness of the emergency call
system on the vehicle can be seen when the
SOS NOT READY display disappears once the
vehicle is switched on.
