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 acci-
dent 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 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 situation.
Messages on the display
