Mercedes-Benz B 250 e 2015, Owner'S Manual

Page: 39 / 293

The seat belt system consists of:
R
seat belts
R
belt tensioners for the front seat belts and the
outer seat belts in the rear
R
belt force limiters for the front seat belts and
the outer seat belts in the rear
If the seat belt is pulled quickly or sharply from
the belt outlet, the inertia reel locks. The belt
strap cannot be pulled out any further.
The belt tensioner tightens the seat belt in the
event of a collision so that it fits tightly across
your body. However, it does not pull the vehicle
occupants back in the direction of the seat
backrest.
The belt tensioner does not, however, correct an
incorrect seat position or correct the routing of
a seat belt that is worn incorrectly.
When triggered, seat belt force limiters help to
reduce the peak force exerted by the seat belt
on the vehicle occupant.
The belt force limiters on the front seats are
synchronised with the front airbags, which take
on a part of the deceleration force. This can
reduce the forces to which the vehicle occu-
pants are subjected during an accident.
!
If the co-driver's seat is not occupied, do not
engage the seat belt tongue in the buckle on
the co-driver's seat. Otherwise, the belt ten-
sioner could be triggered in the event of an
accident and would have to be replaced.
Important safety notes
G
WARNING
The seat belt cannot perform its intended pro-
tective function if it is not fastened correctly.
Also, an improperly fastened seat belt can
cause additional injuries in the event of an
accident, sudden braking or abrupt changes
of direction. There is an increased risk of
injury, possibly even fatal.
Always make sure that all vehicle occupants
are wearing their seat belt properly and are
seated correctly.
G
WARNING
The seat belt does not offer the intended level
of protection if you have not moved the back-
rest to an almost vertical position. When brak-
ing or in the event of an accident, you could
slide underneath the seat belt and sustain
abdomen or neck injuries, for example. This
poses an increased risk of injury or even fatal
injury.
Adjust the seat properly before beginning
your journey. Always ensure that the backrest
is in an almost vertical position and that the
shoulder section of your seatbelt is routed
across the centre of your shoulder.
G
WARNING
Persons under 1.50 m tall cannot wear the
seat belts correctly without a suitable, addi-
tional restraint system. The seat belt cannot
perform its intended protective function if it is
not fastened correctly. Also, an improperly
fastened seat belt can cause additional inju-
ries in the event of an accident, sudden brak-
ing or abrupt changes of direction. There is an
increased risk of injury, possibly even fatal.
Secure persons less than 1.50 m tall in a suit-
able restraint system.
If a child younger than twelve years old and
under 1.50 m in height is travelling in the vehi-
cle:
R
always secure the child in a child restraint
system suitable for this Mercedes-Benz vehi-
cle. The child restraint system must be appro-
priate to the age, weight and size of the child.
R

notes on the automatic front-passenger front
airbag deactivation system (
