Dashboard
The constraints deriving from correct set-up in passive safety perspective was taken into account for designing the
dashboard.
The passenger airbag flap is on the top of the dashboard is positioned to make it impossible to place objects on top
which could be thrown about if the airbag is deployed. This arrangement also ensures that the passenger's airbag is
inflated towards the windscreen rather than towards the occupant and only later stretches into the position where it
provides the best protection.
The lower part of the dashboard is designed to ensure that there is no contact between the occupants' knees and
hard parts which could cause injury to lower limbs in a frontal collision. Furthermore, this risk is additionally reduced
by the presence of a knee bag.
The area underneath the steering column, typically the most dangerous for knees, is protected by an energy
absorber arranged between the column and the upholstery.
The retractable steering column angular adjustment lever and the absence of an ignition switch block (the vehicle is
fitted with a standard electrical steering lock and the start button is located on the dashboard) additionally reduce the
possible areas of contact with the driver's knees in a collision.
Door panels
The arrangement of the functional elements of the panel (i.e. the armrest and the upper part) are designed to ensure
correct interaction with occupant's body in the event of a side collision. The upper part is smooth and soft while the
necessary projection of the armrest is made harmless by collapsing at a load level well under that which may cause
internal injury.
Interior upholstery
Interior upholstery is characterised by soft materials with cover also the necessarily stiff parts, such as front seatbelt
height adjuster. Fireproof material is used (fire propagation speed slower than 100 mm/min) to limit risks in the event
of a fire.
Fire protection
The entire car, from the bodyshell to the various components, was designed in accordance with the Alfa most recent,
strictest fire protection standards. The fuel feed system components are carefully arranged to protect the possible
areas concerned by a collision. Furthermore, the layout of the various systems, followed in detail from the beginning,
is very protected and referenced to prevent criticalities.
Pedestrian protection
The style of the front of the car was developed considering pedestrian protection. Shapes are smooth and rounded.
No risky projections for pedestrians are present. The wide surface of the bonnet minimises the risk of contact
between the pedestrian's head and the stiff front pillars. Inside the engine compartment, the stiffest components are
arranged at a suitable distance from the bonnet to prevent it from absorbing the energy derived from the impact with
the pedestrian's head.

1.2.11 Alarm system

The electronic system consists of the following: transmitter, receiver, ECU with siren, volumetric sensors and anti-
lifting sensors.
The alarm is armed and disarmed by radiofrequency using electronic keys that send an encrypted, variable code. The
electronic alarm monitors: illicit attempt to open doors, bonnet or boot (peripheral protection), operation of the ignition
key, cutting of the battery wires, presence of moving bodies inside the passenger compartment (volumetric
protection) and anomalous lifting/slanting of the vehicle (for versions/markets where fitted).
Volumetric protection can be cut-out.
CAUTION. The engine immobilizer function is ensured by the Alfa Romeo Code system which is activated
automatically when the key is removed from the switch.
The operation of the electronic alarm is adapted at the plant to the standards in force in the various countries.
The approval number of the transmitter is marked on the component for respecting the law in the matter of radio-
frequency devices in countries where this is required. The code marking may also be written on the transmitter and/or
receiver, according to the version/market.
