situations (on vehicles with DISTRONIC
PLUS)
R
in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely
or when having to swerve to avoid an
obstacle at a speed above 85 mph
(140 km/h).
PRE-SAFE
®
takes the following measures
depending on the hazardous situation
detected:
R
the front seat belts are pre-tensioned.
R
under accident conditions, the front-
passenger seat is adjusted if it is in an
unfavorable position.
R
increases the air pressure in the side
bolsters of the seat cushion and seat
backrest of the active multicontour seats in
the front.
R
if the vehicle skids, the sliding roof with
power tilt/sliding panel and the side
windows 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 active multicontour seat
is reduced again. All settings made by PRE-
SAFE
®
can then be reversed.
If the seat belts are not released:
X
When the vehicle is stationary, move the
backrest or seat back slightly.
The belt pretensioning is reduced and the
locking mechanism is released.
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 resetting
the seats. 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"
The NECK-PRO head restraints increase
protection for the driver's and front-
passenger's head and neck. In the event of a
rear collision of a certain severity, the NECK-
PRO head restraints on the driver's and front-
passenger seats are moved forwards and
upwards. This provides better head support.
Do not secure any objects (e.g. coat hangers)
on the NECK-PRO head restraints. Otherwise,
the NECK-PRO head restraints may not
function properly, or in the event of a rear-end
collision may not be able offer the level of
protection they are designed to provide.
Only use seat covers/head restraint covers
that have been tested and approved by
Mercedes-Benz for your model.
Using seat covers and head restraint covers
other than those recommended may cause a
malfunction when NECK-PRO head restraints
are triggered or front side impact air bags/
pelvis air bags may be prevented from
deploying.
Contact an authorized Mercedes-Benz Center
for availability.
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 (
Otherwise, the additional protection will not
be available in the event of another rear-end
collision. You can recognize that NECK-PRO
head restraints have been triggered by the
fact that they have moved forwards and can
no longer be adjusted.
