DESCRIPTION

When operations are carried out to the Air Bag system the recommended safety instructions must be followed precisely. For further details see PROCEDURES 5580C

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’s 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 located under the centre console and is rigidly fixed to the bodyshell: in this way the deceleration sensors located inside it are close to the centre of gravity and detect deceleration for the entire vehicle accurately.

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 clock spring device allows the airbag module connection leads to turn with the steering wheel without the risk of breakage.

The passenger airbag is located on the facia, above the glove compartment, and is fastened directly to the car crossmember via a special bracket.

The passenger Air Bag can be deactivated via a special switch, which can be operated by a key, located under the dashboard in the centre. 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.
