ADDITIONAL SYSTEMS TO THE FRONT SEAT BELTS (continued)
Force 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.
Driver and passenger airbags
An airbag may be provided for both
the driver and the front passenger.
An “Airbag” marking on the
steering wheel and dashboard
(airbag area A)andalabelinthe
lower section of the windscreen
inform you of the presence of
additional means of restraint
(airbags, pretensioners, etc.) in the
passenger compartment.
Each airbag system consists of:
- an airbag and gas generator fitted
on the steering wheel for the
driver and in the dashboard for the
front passenger,
- a computer for both systems,
which includes the impact sensor
and a monitor controlling the
electrical trigger system for the gas
generator;
- a single indicator light on
the instrument panel.

principles of pyrotechnics. This
explains why, when the airbag
inflates, it will generate heat,
produce smoke (this does not mean
that a fire is about to start) and
make a noise upon detonation. In a
situation where an airbag is
required, it will inflate
immediately and this may cause
some minor, superficial grazing to
the skin or other problems.
