vehicles with the memory function: the
front-passenge rseat is adjusted if it is in an
unfavourable position.
R vehicles with amulticontour seat or active
multicontour seat: the air pressure in the
side bolsters of the backrest is increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE ®
slackens
the beltp re-tensioning. On vehicles with mul-
ticontour seats/active multicontour seats,
the air pressure in the side bolsters is reduced
again. All settings made by PRE-SAFE ®
can
then be reversed.
If the seat beltp re-tensioning is not reduced:
X Move the seat backrest or seat back
slightly when the vehicl eisstationary.
Seat beltp re-tensioning is reduced and the

Introduction PRE-SAFE
®
PLUS is only available in vehicles
with the Driving Assistance package.

PRE-SAFE ®
PLUS does not perform braking
actions while the vehicl eisinmotion or when
Parking Guidance is active.
Function PRE-SAFE
®

tions if the rada rsensor system detects an
imminent head-on or rear-end collision.
PRE-SAFE ®
PLUS takes the following meas-
ures depending on the hazardous situation
detected:
R If the rada rsensor system detects that a
head-on collision is imminent, the seat
belts are pre-tensioned.
R If the rada rsensor system detects that a
rear-end collision is imminent:
- the rear hazard warning lamp sare acti-
vated and flas hatahigher frequency.
- the brake pressure is increase difthe
drive rappliest he brakes when the vehi-
cle is stationary.
- the seat belts are pre-tensioned.
The PRE-SAFE ®
PLUS braking application is
cancelled:
R if the accelerator peda lisdepressed when
ag earise ngaged
