PRE-SAFE (anticipatory occupant
protection system)
G WARNING
®
The PRE-SAFE system reduces the impact of
an accident on vehicle occupants, as long as
their seat belts have been fastened correctly.
Although your vehicle is equipped with a PRE-
®
SAFE system, the possibility of injury in the
event of an accident cannot be ruled out. You
should therefore always drive carefully and
adapt your driving style to the prevailing road,
weather and traffic conditions.
®
PRE-SAFE takes preemptive measures to
protect occupants in certain hazardous
situations.
®
PRE-SAFE intervenes:
if 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
R
physical limits are exceeded and the
vehicle understeers or oversteers severely
®
PRE-SAFE takes the following measures
depending on the hazardous situation
detected:
the front seat belts are pre-tensioned.
R
on vehicles with memory function for the
R
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavorable
position.
if the vehicle skids, the panorama roof with
R
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
the belt pre-tensioning. All settings made by
®
PRE-SAFE can then be reversed.
If the seat belts are not released:
When the vehicle is stationary, move the
X
backrest or seat back slightly.
The seat belt pre-tensioning is reduced and
the locking mechanism is released.
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 resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
More information about seat belt adjustment,
a convenience function integrated into PRE-
®
SAFE , can be found in the "Seat belt
adjustment" section (
NECK-PRO head restraints
The NECK-PRO head restraints increase
protection 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.
G
WARNING
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.
G WARNING
Seat or head restraint covers can cause a
malfunction when the NECK-PRO head
®
slackens
restraints are activated or when the side
impact air bags or pelvis air bags are
deployed, or they can prevent this completely.
The NECK-PRO head restraints or side impact
air bags/pelvis air bags can therefore not
