system

PRE-SAFE ® (anticipatory occupant protec‐

PRE-SAFE is able to detect certain critical driv‐
ing situations and implement pre-emptive meas‐
ures to protect the vehicle occupants.
PRE-SAFE ® can implement the following meas‐
ures independently of each other:
Tightening the seat belts on the driver's seat
R
and front passenger seat.
Closing the side windows.

Vehicles with sliding sunroof: close the
R
sliding sunroof.
Internal use only
Occupant safety
Vehicles with memory function: move the
R
front passenger seat to a more favourable
seat position.
Vehicles with multicontour seat: increase
R
the air pressure in the seat side bolsters of
the seat backrest.
PRE-SAFE ® Sound: provided that the multi‐
R

brief noise signal to stimulate the innate pro‐
tective mechanism of a person's hearing.
