Mercedes-Benz E-Class Coupe Owner's Manual page 48

When the roll bars are extended, the rear
head restraints also extend automatically.
Once the roll bars are extended, you can no
longer lower the rear head restraints. The soft
top can no longer be operated. In this case,
visit the nearest qualified specialist work-
shop.
G WARNING
If the roll bar is malfunctioning, the A
Malfunction Consult workshop
appears in the multifunction display. The roll
bars will then not be extended in the event of
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 (preventative occupant
protection)
®
PRE-SAFE takes pre-emptive measures to
protect occupants in certain hazardous sit-
uations.
®
PRE-SAFE intervenes:
in emergency braking situations, e.g. if BAS
R
is activated or for vehicles with DISTRONIC
PLUS, BAS PLUS 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 driving situations, e.g. when phys-
R
ical limits are exceed and the vehicle under-
steers 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: it
R
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
message
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:
Move the backrest or seat back slightly, but
X
only when the vehicle is stationary.
The belt pretensioning is reduced and the
locking mechanism is released.
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.

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 NECK-PRO
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.
