Dependingontheseverityoftheim
pact, the system can cause:
– blocking of the seat belt;
– the seat belt inertia reel pretensioner
which is triggered to correct seat belt
slack;
– the lap seat belt pretensioner to hold
the occupant in their seat;
– the front airbag.
Pretensioners
The pretensioners hold the seat belt
against the body, holding the occupant
more securely against the seat, thus
increasing the seat belt's efficiency.
In the event of a severe frontal impact
and if the ignition is switched on, the

– Only qualified personnel from
our Network may work on the
Airbags; otherwise the system
may trigger accidentally and
cause injury.
– The electrical trigger system
may only be tested by a specially
trained technician using special
equipment.
– When the vehicle is scrapped,
contact an approved dealer for
disposal of the pretensioner and
Airbags gas generators.
Load limiter
Above a certain severity of impact, this
mechanism is used to limit the force of
the belt against the body so that it is at
an acceptable level.
