an accident. This could result in severe or
even fatal injuries to you and other occupants.
In this case, visit a qualified specialist work-
shop immediately and have the roll bar
checked.
PRE-SAFE
®
system
PRE-SAFE ® takes pre-emptive measures to
protect you in certain hazardous situations.
PRE-SAFE
®
intervenes:
R
in emergency braking situations, e.g. if the
BAS Brake Assist System is activated or the
BAS PLUS Brake Assist System intervenes
powerfully
R
if the radar sensor system detects an immi-
nent danger of collision in certain situa-
tions (on vehicles with DISTRONIC PLUS)
R
in critical situations involving driving
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:
R
the front seat belts are pre-tensioned.
R
vehicles with memory functions: under
accident conditions, it adjusts the front-
passenger seat if it is in an unfavourable
position.
R
vehicles with a multicontour seat: the air
pressure in the seat side cushions and in
the backrest side bolsters is increased.
R
if the vehicle skids, the front side windows
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
®
slackens
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.
If the seat belts are not released:
X
Move the backrest or the seat back slightly
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-
SAFE
®
, can be found in the "Belt adjustment"
section (

page 42).
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 (
Y
page 40). Other-
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.
