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 vehicle stability in the event of
tyre grip loss, 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
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.

HH (Hill Holder) SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
uphill: car stationary on a road with
a gradient higher than 5%, engine
running, brake pressed and gearbox in
neutral or gear (other than reverse)
engaged;
downhill: car stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and reverse
gear engaged.
When setting off, the ESC system
control unit maintains the braking
pressure on the wheels until the engine
torque necessary for starting is
reached, or in any case for a maximum
of 2 seconds, allowing your right foot
to be moved easily from the brake
pedal to the accelerator.
When the 2 seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure.
During this release stage, the typical
mechanical brake release noise can be
heard, indicating that the car is about
to move.Moving the car on sloping roads
For optimal starting on very steep
gradients, as follows:
Press the brake pedal to activate the
Hill Holder;
completely press the clutch pedal;
engage the gear;
remove your foot from the brake
pedal;
completely press the accelerator
pedal.
In this manner, the engine goes to the
optimal rpm for taking off uphill. The Hill
Holder remains engaged (car braked)
until the clutch is gradually released
(holding the accelerator pedal pressed):
at this point, the system switches off
and the car starts moving. The Hill
Holder function switches off
automatically if the cars does not
take-off within 2 seconds.
The manoeuvre makes it possible to
avoid pressing the accelerator (because
it must remain fully pressed during the
manoeuvre) and to operate only the
clutch, by gradually releasing it.
Operating the handbrake is not
necessary.
On less steep gradients, the system is
active also with the accelerator pedal
not completely pressed.

ASR (AntiSlip
Regulation) SYSTEM
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.
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.
