head restraints have been triggered by the
fact that they have moved forwards and can
no longer be adjusted.
Mercedes-Benz recommends that you have
the NECK-PRO head restraints checked at a
qualified specialist workshop after a rear-end
collision.

PRE-SAFE (anticipatory occupant
protection)
G WARNING
When adjusting the seat, make sure that
nobody can become trapped.
! 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.
®
PRE-SAFE takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
®
PRE-SAFE intervenes:
when BAS activates, e.g. in emergency
R
braking situations
when BAS PLUS intervenes powerfully on
R
vehicles with DISTRONIC PLUS
if, on vehicles with DISTRONIC PLUS, the
R
radar sensor system detects an imminent
danger of collision in certain situations
in critical driving situations, e.g. when phys-
R
ical limits are exceeded and the vehicle
understeers or oversteers severely
®
PRE-SAFE takes the following measures
depending on the hazardous situation detec-
ted:
the front seat belts are pre-tensioned.
R
vehicles with the memory function: the
R
front-passenger seat is adjusted if it is in an
unfavourable position.
vehicles with a multicontour seat: the air
R
pressure in the side bolsters of the seat
cushion and backrest is increased.
if the vehicle skids, the front side windows
R
and, on the Coupé, the panorama sliding
sunroof, are closed so that only a small gap
remains.
If the hazardous situation passes without
resulting in an accident, PRE-SAFE
the belt pretensioning. The air pressure in the
side bolsters on the multicontour seat is
reduced again. All settings made by PRE-
®
SAFE can then be reversed.
