network, which ensures faster placement of
the emergency call and faster transfer of the
accident data.
Measures for rescue, recovery or towing
away can then be initiated in quickly.
R
With a Mercedes-Benz emergency call, the
accident data is only transferred to the pub‐
lic coordination centre with the approval of
the customer.
In the event of an automatically triggered
emergency call in which there is no voice
contact, the accident data is transmitted
immediately to the public emergency call
centre.
R
Should the Mercedes-Benz emergency call
centre not be available, the 112 emergency
call is carried 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
accident site in places that are difficult to
access.
Both emergency call systems can initiate an
emergency call automatically (/ page 409) or
manually .
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 sit‐
uation.
Messages on the display
The following messages appear in the display of
both emergency call systems:
R
SOS NOT READY: the ignition is not on or
eCall is not available. This does not necessa‐
rily indicate complete failure of the emer‐
gency call system. Emergency calls call 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 emergency 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 ignition is switched on.
R
G: The icon appears in the display during
an active emergency call.
%
If there is an emergency call system mal‐
function (e.g. a fault in the loudspeaker,
microphone, airbag, SOS button) a relevant
message appears in the driver display of the
instrument cluster.
