ACTIVE SAFETY SYSTEMS
ABS (Anti-lock Braking 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 car can be controlled
even during emergency braking and
optimising stopping distances.
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 (Electronic Brake Force
Distribution) SYSTEM
This system manages the distribution of
the braking torque between the front and
rear axles by limiting braking pressure
to the rear axle. This is done to prevent
overslip of the rear wheels to avoid car
instability, and to prevent the rear axle
from entering ABS before the front axle.
ASR (AntiSlip Regulation) SYSTEM
The system automatically operates in
the event of slipping, loss of grip on wet
roads (aquaplaning) and acceleration on
slippery, snowy or icy roads, etc. on one
or more drive wheels.
DTC (Drag Torque Control) SYSTEM
The DTC (Drag Torque Control) system
prevents the drive wheels from possibly
locking, which could happen, for example,
if the accelerator pedal is released
suddenly or in the case of a sudden
downshifting in conditions of poor grip.
In these conditions, the engine braking
effect could cause the drive wheels to
slip, resulting in a loss of car stability.
In these situations, the DTC system
intervenes, restoring torque to the motor
in order to conserve car stability and
increase car safety.
ESC (Electronic Stability Control)
SYSTEM
The ESC system improves directional
control and vehicle stability under
different driving conditions, correcting
understeering and oversteering and
distributing the brakeforce on the
appropriate wheels.
System intervention
The system intervention is signalled
by the flashing of the instrument panel
warning light
, to inform the driver
that the car is in critical stability and grip
conditions.

TC (Traction Control) SYSTEM
The system automatically operates in
the event of slipping, loss of grip on wet
roads (aquaplaning) and acceleration on
slippery, snowy or icy roads, etc. on one
or both drive wheels.
System intervention
The system intervention is signalled
by the flashing of the instrument panel
warning light
, to inform the driver
that the car is in critical stability and grip
conditions.
49) 50) 51) 52) 53)
PBA (Panic Brake Assist) SYSTEM
The PBA system is designed to improve
the car’s braking capacity during
emergency braking.
The brake pedal should be pressed
continuously during braking, avoiding
intermittent presses, to get the most out
of the system. Do not reduce pressure on
the brake pedal until braking is no longer
necessary.
The PBA system is deactivated when the
brake pedal is released.
49) 50) 51)
BLD (Brakes Lock Differential)
SYSTEM
The BLD system, acting on the brakes,
distributes engine torque to the wheel
with the most grip so as to disengage the
car in low-grip conditions.
