PRE-SAFE
®
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 pre-emptive measures to
protect occupants in certain hazardous
situations.
PRE-SAFE
®
intervenes:
R
in emergency braking situations, e.g. if BAS
is activated or, in vehicles with DISTRONIC
PLUS, where BAS PLUS intervenes
powerfully
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
PRE-SAFE
®
takes the following measures
depending on the hazardous situation
detected:
R
the front-passenger seat is adjusted if it is
in an unfavorable position.
R
it 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 side windows and
sliding sunroof are closed so that only a
small gap remains.
If the sliding sunroof or a side window is
obstructed when closing, the closing
procedure is stopped. The obstructed sliding
sunroof or side window then opens again
slightly.
If the hazardous situation passes without
resulting in an accident, all settings made by
PRE-SAFE
®
can be reversed. The air pressure
in the side bolsters on the active multicontour
seat is reduced again.
If the seat belts are not released:
X
Move the backrest back slightly, but only
when the vehicle is stationary.
The belt pretensioning 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.
Seat belts
Important safety notes
The use of infant or child restraint systems is
required by law in all 50 states, the District of
Columbia, the U.S. territories and all
Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened when the vehicle is in motion.
i
See "Children in the vehicle"
(
Y
page 56) for more information on
infants and children traveling with you in
the vehicle and restraints for infants and
children.
G
Warning!
Always fasten your seat belt before driving off.
Always make sure all of your passengers are
properly restrained. You and your passengers
should always wear seat belts.
Failure to wear and properly fasten and
position your seat belt greatly increases your
risk of injuries and their likely severity in an
accident.
If you are ever in an accident, your injuries can
be considerably more severe without your
Occupant safety
