G WARNING
If the 45 indicator lamp does not illuminate or remains out with the weight of a typical
12-month-old child in a standard child restraint or less, or is unoccupied, on the front-passenger

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:
R if BAS PLUS intervenes powerfully on
vehicles with DISTRONIC PLUS
R if, on vehicles with DISTRONIC PLUS, the
radar sensor system detects an imminent
danger of collision in certain situations
R in critical driving situations, e.g. when
physical limits are exceeded and the
vehicle understeers or oversteers severely
PRE-SAFE ® takes the following measures
depending on the hazardous situation
detected:
R the front seat belts are pre-tensioned.
R on vehicles with memory function for the
front-passenger seat: the front-passenger
seat is adjusted if it is in an unfavorable
position.
R if the vehicle skids, the sliding sunroof,
panorama 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 pre-tensioning. 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 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 (
Y
page 56).
NECK-PRO head restraints/NECK-
PRO luxury head restraints (except
AMG vehicles)
G WARNING
The function of the head restraint may be
impaired if you:
R attach objects such as coat hangers to the
head restraints, for example
R use head restraint covers
If you do so, the head restraints cannot fulfill
their intended protective function in the event
of an accident. In addition, objects attached
to the head restraints could endanger other
