SYSTEM INTERVENTION
This is indicated by the flashing of the
warning light on the instrument
panel, to inform the driver that the car is
in critical stability and grip conditions.
ABS
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 car
can be controlled even during
emergency braking and optimising
stopping distances.
The system intervenes when braking
and the wheels are about to lock,
typically in emergency braking or
low-grip conditions, when locking may
be more frequent.
The system also improves control and
stability of the car when braking on a
surface where the grip of the left and
right wheels varies, or on corners.

System intervention
A slight pulsing of the brake pedal and
noise indicates the intervention of the
ABS: this is completely normal when
the system intervenes.
EBD SYSTEM
The EBD system is an integral part of
the ABS system and intervenes during
braking, distributing the brake force
optimally between front and rear
wheels.
This guarantees greater braking stability
for the vehicle, preventing sudden
locking of the rear wheels and
the consequent instability of the vehicle.
CBC (Cornering Brake
Control) SYSTEM
The system acts when braking on
corners, optimising the distribution of
brake pressure on the four wheels: the
system prevents the wheels on the
inside of the corner (less affected by the
weight of the car) from locking,
ensuring better stability and direction
for 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.
ASR (AntiSlip
Regulation) SYSTEM
29) 30) 38) 39) 40)
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.
Depending on the slipping conditions,
two different control systems are
activated:
❒ if the slipping involves both drive
wheels, the ASR system intervenes,
reducing the power transmitted by
the engine;
❒ if the slipping only involves one of the
drive wheels, it also intervenes
automatically, braking the wheel that
is slipping.
