Description
The car is fitted with an electronically-controlled
safety system which, in the case of a front-end crash of some severity,
activates the driver's and passenger Air Bags.The electronic control unit manages the
entire system, checking all the components and when necessary activating
the Air Bags.The control unit is situated on the floor
in a central position under the dashboard, and is secured rigidly
to the bodywork; in this way the deceleration sensors located inside
it are near the baricentre and can detect precisely the deceleration
of the entire car.The driver's Air Bag module is located in
the centre of the steering wheel; it is fitted on a tilting plate
which enables the horn to be operated. The plate houses a metal
container which holds the folded airbag and a gas generator that
inflates the bag.A clockspring cable allows the Air Bag module
connecting cables to follow the rotation of the steering wheel without
the risk of breaking.The two passenger Air Bag modules (two gas
generators which inflate a large single bag) are located in the
dashboard, fixed directly to the vehicle crossmember by a special bracket.The passenger Air Bag can be manually deactivated
via a special switch - which can be operated by a key - located
above the dashboard in the driver's glove compartment.When the key is turned to OFF, the control
unit also controls the activation of a passenger air bag disablement
warning light on the instrument panel.The control unit comes with a self-diagnostic
function.
- it detects and memorizes any faults
- it recognizes the various components and the type of fault
- it signals the onset of these faults via the special warning
light.
System activations following a particularly
serious impact are memorized by the control unit.
