ACTIVE SAFETY SYSTEMS

ABS SYSTEM
This system, which is an integral part of
the braking system, prevents one or
more wheels from locking and slipping in
all road surface conditions, irrespective
of the intensity of the braking action,
ensuring that the vehicle can be
controlled even during emergency
braking and optimising stopping
distances.
System intervention
The driver can feel that the ABS system
has come into action because the brake
pedal pulsates slightly and the system
gets noisier: this is entirely normal with
the system operating.

ASR (AntiSlip Regulation) SYSTEM
37) 38) 39)
This is an integral part of the ESC system
and automatically operates in the event
of one or both drive wheels slipping, loss
of grip on wet roads (aquaplaning) and
acceleration on slippery, snowy or icy
roads, etc.
System intervention
The system intervenes on the engine
power and the brakes.
It is indicated by the flashing of the
warning light on the instrument panel,
to inform the driver that the vehicle is
in critical stability and grip conditions.
HBA (Hydraulic Brake Assist) SYSTEM
40) 41) 42)
The HBA system is designed to improve
the car's braking capacity during
emergency braking: the HBA system
therefore completes the ABS system.
Maximum assistance from the HBA
system is obtained by continuously
pressing the brake pedal very quickly.
EBD SYSTEM
The EBD system is an integral part of the
ESC system and intervenes during
braking, distributing the brake force
optimally between front and rear wheels.
This guarantees greater braking stability
for the car, preventing sudden locking of
the rear wheels and the consequent
instability of the car.
DTC (Drag Torque Control) SYSTEM
This is an integral part of the ABS
system and intervenes in the case of
sudden downshifting, or during braking
when the ABS intervenes, restoring
torque to the engine and thus preventing
excessive drag at the drive wheels, which
may lead the wheels to lock and a loss of
car stability, above all in low-grip
conditions.
