ACTIVESAFETY
SYSTEMS
The vehicle has the following active
safety systems:
ABS (Anti-lock Braking System);
EBD (Electronic Brake force
Distribution);
DTC (Drag TorqueControl);
ESC (Electronic Stability Control);
HH (Hill Holder);
ASR (Antislip Regulation);
PBA (Panic Brake Assist);
TTC (Torque Transfer Control)
For the operation of the systems, see
the following description.
ABS(Anti-lockBraking
System)
This system, which is an integral part
of the braking system, prevents one
or more wheels from locking and
slipping in any roadsurface condition,
irrespective of theintensity of the
braking action, ensuring that the
car can be controlled even during
emergency braking thus optimising
stopping distances.
The system intervenes during braking
when the wheelsare 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 carwhen braking on a
surface where thegrip of the left and
right wheels varies, or on corners.
The Electronic Braking Force
Distribution (EBD) system completes
the system allowing the brake force to
be distributed between the front and
rear wheels.
Systemintervention
A slight pulsing of the brake pedal and
noise indicates theintervention of the
ABS: this is completely normal when
the system intervenes.

DTC(DragTorque
Control)SYSTEM
The 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
engine in order to conserve vehicle
stability and increase vehicle safety.
ESC(ElectronicStability
Control)SYSTEM
The ESC systemimproves the
directional controland stability of
the car in various driving conditions.
The ESC systemcorrects the car’s
understeer and oversteer, distributing
the brake force onthe wheels
appropriately. Thetorque supplied by
the engine can also be reduced in
order to maintain control of the vehicle.
The ESC systemuses sensors installed
on the car to determine the trajectory
that the driver intends to follow and
compares it with the car’s effective
trajectory. When the real trajectory
deviates from the desired trajectory, the
ESC system intervenes to counter the
vehicle’s understeer or oversteer.
Oversteer:occurs when the car is
turning more thanit should with
respect to the angle of the steering
wheel.
Understeer: occurs when the caris
turning less than itshould with respect
to the angle of thesteering wheel.
Systemintervention
The system intervention is signalled
by the blinking of the instrument panel
warning light
, to inform the driver
that the car is in critical stability and
grip conditions.

HH(HillHolder)SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activatingautomatically in the
