Automatic comfort-fit feature seat belt
The automatic comfort-fit feature reduces the
retracting force of the seat belts when they
are in normal use. It is available for the front
seats and for the rear outer seats (only for
vehicles with rear power seats).
Preventive occupant safety (PRE-
SAFE ®
)
GWarning!
The PRE-SAFE ®
system is intended to reduce
the effects of an accident on vehicle
occupants who are wearing their seat belt
properly. Despite your vehicle being equipped
with the PRE-SAFE ®
system, the possibility of
personal injuries occurring as a result of an
accident cannot be eliminated. Therefore,
always drive carefully and adjust your driving
to the prevailing road, weather, and traffic
conditions.
The PRE-SAFE ®
system takes preventive
measures to better protect the occupants
from the possibility of personal injuries in the
following hazardous situations:
R emergency braking situations, e.g. if the
Brake Assist System (BAS) ( Y page 64) is
activated
or when
vehicles with DISTRONIC PLUS:
the BAS PLUS ( Y page 64) or the PRE-
SAFE ®
Brake ( Y page 69) is strongly
engaging
R when the radar sensors recognize the
immediate risk of collision in certain
situations (vehicles with DISTRONIC PLUS)
R critical dynamic driving situations, e.g.
when the vehicle has been caused to
understeer or oversteer because it has
exceeded its physical limitations or in case
of evasive steering maneuvers at speeds
above approximately 85 mph (140 km/h)
The PRE-SAFE ®
system takes the following
measures when it is activated:
R The front seat belts are pre-tensioned
automatically.
R If the front passenger seat is in an
unfavorable position, the seat will be
adjusted to a position that seeks to better
protect the occupant.
R If a rear outer power seat (if so equipped)
is in an unfavorable position, the seat will
be adjusted to a position that seeks to
better protect the occupant.
R The system increases the air pressure in
the air pockets (on the sides of the seat
cushion and backrest) of the multicontour
and/or drive-dynamic multicontour front
seats.
R If the vehicle is equipped with multicontour
rear seats, the system increases the air
pressure in the air pockets (on the sides of
the seat backrest) of the multicontour rear
outer seats.
R If the vehicle is in a critical dynamic driving
situation, the door windows and the tilt/
sliding sunroof or panorama roof with tilt/
sliding panel also closes, except for a
minimal gap that remains open.
If the closing procedure of any of these
elements is blocked, it will stop and open
slightly.
Once the hazardous situation no longer exists
and an accident has been avoided, the PRE-
SAFE ®
system loosens the seat belt pre-
tension and decreases the air pressure in the
air pockets of the multicontour and/or drive-
dynamic multicontour seats. All of the PRE-
SAFE ®
system settings can be re-adjusted
following the critical driving event.
If the seat belts do not release:XAdjust the seat backrest to the rear until
the seat belt tension is reduced.
The locking mechanism releases.54Occupant safetySafety and security

XVehicles with rear center seat: Make sure
that the seat belt for the rear center seat
can operate freely with a child seat
installed.
GWarning!
Vehicles with rear power seats:
Never change the rear seat position after
installing the child restraint. This could
Rdamage the child restraint
Rintroduce undesirable slack or tension into
the seat belt
Rloosen the child restraint
Rmisposition the child restraint
All of the above will lessen the
effectiveness of the child restraint and thus
increase the chance or severity of injury in
an accident.
Child safety
Child safety locks
GObserve Safety notes, see page 56.GWarning!
Children could open a rear door from the
inside. This may cause serious personal injury
or an accident. Therefore, secure the rear
doors with the child safety locks whenever
children are riding in the back seats of the
vehicle.
The child safety locks on the rear doors
enable you to secure each rear door
individually. You cannot open a secured rear
door from the inside. You can open the rear
door from the outside when the vehicle is
unlocked.
XSecuring: Press the lever up in direction of
arrow \000F.
XCheck to make sure the child safety locks
are working properly.
XReleasing: Press the lever down in
direction of arrow \000G.
Override switch
GObserve Safety notes, see page 56.
You can disable select functions in the rear
passenger compartment for added safety.
This can be useful, for instance, when you
have children riding in the rear passenger
compartment.
You can disable the following functions:
Rrear door window operation
Radjustment of front passenger seat from
the rear
Rrear center console lighter
Rrear roller sunblind for panorama roof
Rrear window sunshade and rear door
window sunshades
GWarning!
Activate the override switch when children
are riding in the back seats of the vehicle. The
children may otherwise injure themselves,
e.g. by becoming trapped in the rear door
window opening.
