Overview of the Mercedes-Benz emergency
call system
eCall can help to reduce the time between an
accident and the arrival of emergency services
at the site of the accident. It helps locate an
accident site in places that are difficult to
access. However, even if a vehicle is equipped
with eCall, this does not mean the system is ON.
As such, eCall does not replace dialing 911 in the
event of an accident.
An emergency call can be made automatically
( page 301) or manually ( page 302). Only
/ /
make emergency calls if you or others are in

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.
Displays in the media display:
SOS READY: eCall available
