R
vehicles with the memory function: the
front-passenger seat is adjusted if it is in an
unfavourable position.
R
vehicles with a multicontour 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 belt pre-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 belt pre-tensioning is not reduced:
X
Move the seat backrest or seat back
slightly when the vehicle is stationary.
Seat belt pre-tensioning is reduced and the
locking mechanism is released.
The seat-belt adjustment is an integral part of
the PRE-SAFE
®
convenience function. Infor-
mation about the convenience function can
be found under "Belt adjustment"
(

PRE-SAFE
®
PLUS (anticipatory occu-
pant protection PLUS)
Introduction
PRE-SAFE
®
PLUS is only available in vehicles
with the Driving Assistance package.
Using the radar sensor system, PRE-SAFE
®
PLUS is able to detect that a head-on or rear-
end collision is imminent. In certain hazard-
ous situations, PRE-SAFE
®
PLUS takes pre-
emptive measures to protect the vehicle
occupants.
Important safety notes
The intervention of PRE-SAFE
®
PLUS cannot
prevent an imminent collision.
The driver is not warned before the interven-
tion of PRE-SAFE
®
PLUS.
PRE-SAFE
®
PLUS does not intervene:
R
if the vehicle is reversing
R
when the vehicle is towing a trailer and
there is a risk of a rear-end collision
PRE-SAFE
®
PLUS does not perform braking
actions while the vehicle is in motion or when
Parking Guidance is active.
Function
PRE-SAFE
®
PLUS intervenes in certain situa-
tions if the radar sensor 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 radar sensor system detects that a
head-on collision is imminent, the seat
belts are pre-tensioned.
R
If the radar sensor system detects that a
rear-end collision is imminent:
-
the rear hazard warning lamps are acti-
vated and flash at a higher frequency.
-
the brake pressure is increased if the
driver applies the 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 pedal is depressed when
a gear is engaged
R
if the risk of a collision passes or is no lon-
ger detected
R
if DISTRONIC PLUS indicates an intention
to pull away
If the hazardous situation passes without
resulting in an accident, the original settings
are restored.
