Seats, restraints43Seat belts
The seat belts are locked during
heavy acceleration or deceleration of
the vehicle, holding the occupants in
the seat position. Therefore the risk of injury is considerably reduced.

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 52.
Periodically check all parts of the belt
system for damage, soiling and
proper functionality.
Have damaged components
replaced. 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 X 3 91.
Belt force limiters
On the front seats, 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 or rear-end
collision of a certain severity, the front seat belts are tightened.9 Warning
Incorrect handling ( e.g. removal or
fitting of belts) can trigger the belt
pretensioners.
