Occupant safety

Have roll bars checked immediately at a quali-
fied specialist workshop.
G WARNING
If you place objects or clothing on the roll bar
covers, these could impair roll bar extension.
The roll bars may then not protect the vehicle
occupants as intended. In addition, objects
could endanger the vehicle occupants when
the roll bar is extending. This poses an
increased risk of injury or even fatal injury.
Ensure that the movement area of the roll bar
covers is kept clear. Always stow all objects in
the vehicle correctly.
The roll bars are located in the rear area of the
vehicle under the two outer rear compart-
ment trim covers.
The roll bars are extended automatically if
systems detect that the vehicle is in danger of
overturning. The two rear compartment trim
covers are opened and the roll bars are exten-
ded within fractions of a second.
Once the roll bars are extended, you can no
longer lower them. An open roof can no lon-
ger be closed. In this case, visit the nearest
qualified specialist workshop.

PRE-SAFE (anticipatory occupant
protection)
Introduction
®
PRE-SAFE takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
Important safety notes
! Make sure that there are no objects in the
footwell or behind the seats when moving
the seat back. There is a risk that the seats
and/or the objects could be damaged.
Although your vehicle is equipped with a PRE-
®
SAFE system, the possibility of injury in the
event of an accident cannot be ruled out.
Always adapt your driving style to suit the
prevailing road and weather conditions and
maintain a safe distance from the vehicle in
front. Drive carefully.
Function
®
PRE-SAFE intervenes:
in emergency braking situations, e.g. when
R
BAS is activated
in critical driving situations, e.g. when phys-
R
ical limits are exceeded and the vehicle
understeers or oversteers severely
on vehicles with DISTRONIC PLUS: if
R
BAS PLUS brakes hard or the radar sensor
system detects an imminent danger of col-
lision in certain situations
®
PRE-SAFE takes the following measures
depending on the hazardous situation detec-
ted:
the seat belts are pre-tensioned.
R
if the vehicle skids, the side windows are
R
closed so that only a small gap remains.
the front-passenger seat is adjusted if it is
R
in an unfavourable position.
Vehicles with a multicontour seat or
R
active multicontour seat: the air pres-
sure in the side bolsters of the backrest is
increased.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE
the belt pre-tensioning. All settings made by
®
PRE-SAFE can then be reversed.
