▌ 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 573) or man-
ually (
/
page 574).
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 for both emergency call systems:
R
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 call still be transmitted.
The display only refers to the vehicle and does
not take account of the availability of mobile
