METHODS OF RESTRAINT IN ADDITION TO THE FRONT SEAT BELTS
These are:
buckle pretensioners,
lap strap pretensioners,
chest force limiters,
driver and passenger
airbags.
These systems are designed to act
independently or together when the
vehicle is subjected to a frontal
impact.
Depending on the force of the
impact the system may activate:
- seat belt locking,
- the buckle pretensioner (which is
triggered to take up the seat belt
play),
- the lap belt pretensioner to keep
the occupant in their seat, the low
volume front airbag and the force
limiters,
- the large volume front airbag.

Pretensioners
With the ignition switched on, if
there is a severe frontal impact and
depending on the force of the
impact, the system may engage:
- piston 1
retracts the seat belt,
- piston 2 on the front seats.
The pretensioners hold the seat belt
against the body, holding the
occupant more securely against the
seat, thus increasing the seat belt's
efficiency.

system checked
• No operation whatsoever is
permitted on any part of the
system (pretensioners, airbags,
computers, wiring)
system components must not be

the pretensioner and airbag
system.
• Testing of the electric trigger
system may only be carried out
by a specially trained technician
using special equipment.
