ACTIVE SAFETY
SYSTEMS
The vehicle has the following active
safety systems:

ABS (Anti-lock Braking System);

EBD (Electronic Brake force
Distribution);
MSR (Motor Schleppmoment
Regelung);
ESC (Electronic Stability Control);
HH (Hill Holder);
ASR (Antislip Regulation);
HBA (Hydraulic Brake Assist);
For the operation of the systems, see
the following description.
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 any road surface condition,
irrespective of the intensity 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 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 (Electronic
Brakeforce Distribution)
SYSTEM
This system (which cannot be
deactivated) recognises emergency
braking conditions according to the
speed of operation of the brake pedal
and provides an additional hydraulic
braking pressure to support that
provided by the driver. This allows
faster and more powerful operation of
the braking system.
MSR (Motor
Schleppmoment
Regelung) SYSTEM
The MSR system is an integral part of
the ABS, that intervenes, if there is
a sudden change to a lower gear,
restoring torque to the engine, thereby
preventing excessive drive at the drive
wheels which, especially in poor grip
conditions, could lead to a loss in
stability of the vehicle.
ESC (Electronic Stability
Control) SYSTEM
This is an electronic system that
controls car stability in the event of loss
of tyre grip, helping maintain directional
control.
The system is capable of recognising
potentially dangerous situations in
terms of the stability and intervenes
automatically on the brakes in a
differentiated manner for the four
wheels in order to provide a stabilising
torque.
The ESC system switches on
automatically when the engine is
started and cannot be switched off.
System intervention
It is signalled by the blinking of the
instrument panel warning light
inform the driver that the car is in
critical stability and grip conditions.

HH (Hill Holder) SYSTEM

This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:

a gradient higher than 5%, engine
running, brake pressed and gearbox
