Safety
Airbags
The airbags are designed to help enhance the
safety of occupants in the event of a serious
collision. They complement the action of the
safety belts equipped with force limiters.
If a collision occurs, the electronic detectors
record and analyse the front and side impacts
sustained in the impact detection zones:
- if there is a violent impact, the airbags
deploy instantly and help better protect
occupants of the vehicle; immediately after
the impact, the airbags deflate rapidly
in order not to hinder the visibility or the
possible exit of the occupants.
- in the case of a minor or rear impact or in
certain roll-over conditions, the airbags
may not be deployed; the seat belt
alone contributes towards ensuring your
protection in these situations.
The airbags do not operate when the
ignition is switched off.
This equipment will only deploy once. If a
second impact occurs (during the same or
a subsequent accident), the airbag will not
be deployed again.

Impact detection zones
A. Front impact zone.
B. Side impact zone.
Airbag deployment generates slight
smoke emissions and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
This smoke is not harmful, but sensitive
individuals may experience slight irritation.
The detonation noise associated with the
deployment of an air bag may result in a
slight loss of hearing for a short time.

Front airbags
This system protects the driver and front
passenger from the risk of injury to the head
and chest in the event of a severe frontal
impact.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger's airbag is
fitted in the dashboard above the glove box.
Activation
The airbags are deployed (except the
passenger's front airbag if it is deactivated) in
the event of a severe frontal impact to all or part
of the frontal impact zone A, in the longitudinal
centreline of the vehicle on a horizontal plane
and directed from the front to the rear of the
vehicle.
The front airbag inflates between the front
occupant of the vehicle and the dashboard, to
cushion their forward movement.
