ACTIVE SAFETY
SYSTEMS
The car has the following active safety
systems:
ABS (Anti-lock Braking System);
EBD (Electronic Brake force
Distribution);
MBA (Mechanical Brake Assist);
ESC (Electronic Stability Control);
HH (Hill Holder);
ASR (Antislip Regulation);
BA (Brake Assist);
MSR (Motor Schleppmoment
Regelung);
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 all road surface conditions,
irrespective of the intensity of the
braking action, ensuring that the vehicle
can be controlled even during
emergency braking.IMPORTANT To obtain the maximum
efficiency of the braking system, a
bedding-in period of about 500 km is
needed: during this period it is better to
avoid sharp, repeated and prolonged
braking.
System intervention
The driver can feel that the ABS has
come into action because the brake
pedal pulsates slightly and the system
gets noisier: it means that the vehicle
speed should be altered to suit the type
of road surface.41) 42) 43) 44) 45) 46) 47) 48)
EBD (Electronic
Brakeforce Distribution)
SYSTEM
The EBD system allows the brake force
to be distributed between the front
and rear wheels.
MBA (Mechanical brake
assist) 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.
49)
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
It is signalled by the flashing of theESC
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:
66
SAFETY

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 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.
IMPORTANT The Hill Holder system is
not active with engaged parking brake.IMPORTANT The Hill Holder system is
not a parking brake, therefore do not
leave the car without activating the
handbrake, switching off the engine,
and engaging first gear, with the car
parked in safe conditions.
IMPORTANT The Hill Holder system is
not active with engaged parking brake.
If the parking brake is engaged and
at the same time you press the brake
pedal, the Hill Holder system is
activated only if the parking brake is
disengaged before releasing the brake
pedal.
56)
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 intervenes reducing
the power transmitted by the engine;
if the slipping only involves one of
the drive wheels, it intervenes
automatically braking the wheel that is
slipping.
Turning the ASR system on/off
The ASR is switched on automatically
each time the engine is started.
While driving, the ASR can be switched
off and subsequently switched on
again by pressing the ASR OFF button
fig. 47.
On some versions, the intervention of
the system is indicated by a dedicated
message shown on the display.
When the system is not active, the LED
on the button ASR OFF turns on and,
on some versions, a message appears
on the display. When the ASR is
deactivated while driving, the next time
the car is started the ASR is
automatically activated.

When travelling on snowy roads with
snow chains, it may be helpful to turn
the ASR off: in fact, in these conditions,
the driving wheels skidding when
moving off gives you better traction.
57) 58) 60) 60) 61) 62)
BA (Brake Assist)
SYSTEM
The system, which cannot be turned
off, recognises emergency braking (on
the basis of the brake pedal operating
speed) and speeding up the response
of the braking system. The Brake Assist
device is deactivated if there is a ESC
system failure.
MSR (Motor
Schleppmoment
Regelung) SYSTEM
This system is an integral part of the
ABS that intervenes, if there is a
sudden downshifting, 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 car.HBA (Hydraulic Brake
Assist) SYSTEM
It is an integral part of the ESC system.
The HBA system is designed to
improve the car’s braking capacity
during emergency braking.
The system detects an emergency
braking by monitoring the speed and
strength with which the brake pedal
is pressed, thereby applying the optimal
brake pressure. This can reduce the
braking distance: the HBA system
therefore completes the ABS.
Maximum assistance of the HBA
system is obtained pressing the brake
pedal very quickly; in addition, the
brake pedal should be pressed
continuously during braking, avoiding
intermittent presses, to obtain benefits
from the system.
Do not reduce pressure on the brake
pedal until braking is no longer
necessary.
The HBA system is deactivated when
the brake pedal is released.

WARNING
41)The ABS gets the most from the
available grip, but it cannot improve it; you
should therefore take every care when
driving on slippery surfaces and not take
unnecessary risks.
42)When the ABS cuts in and you feel the
brake pedal pulsating, do not remove
your foot, but keep the pedal pushed
down; in doing so you, will stop in the
shortest distance possible under the road
conditions at the time.
43)If the ABS system intervenes, this
indicates that the traction of the tyres on
the road is nearing its limit. You must slow
down to a speed compatible with the
available traction.
44)The ABS cannot overrule the natural
laws of physics, and cannot increase
the grip available according to the
condition of the road.
45)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
46)The capability of the ABS must never
be tested irresponsibly and dangerously, in
such a way as to compromise personal
safety and the safety of others.
47)For the correct operation of the ABS,
the tyres must of necessity be the same
make and type on all wheels, in perfect
condition and, above all, of the prescribed
type and dimensions.
