In this case, visit a qualified specialist work-

PRE-SAFE system
®
PRE-SAFE takes pre-emptive measures to
protect you in certain hazardous situations.
®
PRE-SAFE intervenes:
in emergency braking situations, e.g. if the
R
BAS Brake Assist System is activated or the
BAS PLUS Brake Assist System intervenes
powerfully
if the radar sensor system detects an immi-
R
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
in critical situations involving driving
R
dynamics, e.g. if the vehicle oversteers or
understeers significantly due to physical
limits being exceeded or if the vehicle
swerves to avoid an obstacle at a speed of
over 140 km/h.
®
PRE-SAFE takes the following measures
depending on the hazardous situation detec-
ted:
the front seat belts are pre-tensioned.
R
vehicles with memory functions: under
R
accident conditions, it adjusts the front-
passenger seat if it is in an unfavourable
position.
vehicles with a multicontour seat: the air
R
pressure in the seat side cushions and in
the backrest side bolsters 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
If the seat belts are not released:
Move the backrest or the seat back slightly
X
until the belt pretensioning is reduced.
The locking mechanism releases.
G Warning
Make sure that nobody can become trapped
as you adjust the seat.
!
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.
More information about belt adjustment, a
convenience function integrated into PRE-

NECK-PRO head restraints
The NECK-PRO head restraints increase pro-
tection to the driver's and front-passenger's
head and neck. To this end, the head
restraints on the driver's and front-passenger
seats are moved forwards and upwards in the
event of a rear-end collision of a certain
severity. This provides better head support.
G
Risk of injury
Head restraint covers prevent the NECK-PRO
head restraints from triggering correctly. Con-
sequently, the NECK-PRO head restraints
cannot provide the intended level of protec-
tion. Do not use head restraint covers.
If the NECK-PRO head restraints have been
triggered in an accident, you must reset the
NECK-PRO head restraints on the driver's and
front-passenger seat (
wise, the additional protection will not be
available in the event of another rear-end col-

lision. You can recognise when NECK-PRO
head restraints have been triggered by the
fact that they have moved forwards and can
no longer be adjusted.
