50Seats, restraintsSeat belts
The seat belts are locked during
heavy acceleration or deceleration of
the vehicle, holding the occupants in
the seat position. Thereby the risk of
injury is considerably reduced.
9 Warning
Fasten seat belt before each trip.
In the event of an accident, people
not wearing seat belts endanger their fellow occupants and
themselves.
Seat belts are designed to be used by only one person at a time. Child
restraint system 3 58.
Periodically check all parts of the belt
system for damage, soiling and
proper functionality.
Have damaged components replaced by a workshop. After an accident,
have the belts and triggered belt
pretensioners replaced by a
workshop.
Notice
Make sure that the belts are not
damaged by shoes or sharp-edged objects or are trapped. Prevent dirt
from getting into the belt retractors.
Seat belt reminder
Each seat is equipped with a seat belt reminder, indicated for front seats by
control indicators X and k, or for rear
seats by the symbol X in the Driver
Information Centre 3 96.
Belt force limiters
Stress on the body is reduced by the
gradual release of the belt during a
collision.Belt pretensioners
In the event of a head-on, rear-end or
side-on collision of a certain severity,
the front and rear seat belts are
tightened. The front seat belts and the outer rear seat belts are tightened by
one pretensioner per seat.9 Warning
Incorrect handling (e.g. removal or
fitting of belts) can trigger the belt
pretensioners.
Deployment of the belt pretensioners
is indicated by continuous illumination
of control indicator v 3 97.
Triggered belt pretensioners must be replaced by a workshop. Belt
pretensioners can only be triggered
once.
Notice
Do not affix or install accessories or
other objects that may interfere with
the operation of the belt
pretensioners. Do not make any
modifications to belt pretensioner components as this will invalidate
the operating permit of your vehicle.

rear part of the bonnet will be lifted to
reduce pedestrians head injuries.
In addition the front bumper is
designed to reduce leg injuries of
pedestrians.
The active bonnet can be triggered
only once and remains in the raised
position. A message is displayed in
the Driver Information Centre.
Seek the assistance of a workshop as soon as possible, thereby adapting
the driving style, to have the
actuators, hinges and bonnet
replaced.9 Warning

damaged. Consult a workshop to
verify proper functionality of the
sensors.
