ACTIVE SAFETY SYSTEMS
ABS 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 and optimising stopping
distances.
System intervention
The driver can feel that the ABS system
has come into action because the brake
pedal pulsates slightly and the system
gets noisier: this is entirely normal with
the system operating.
30) 31) 32) 33) 34) 35) 36)
ASR (AntiSlip Regulation) SYSTEM
37) 38) 39)
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.
System intervention
The system intervenes on the engine
power and the brakes.
It is indicated by the flashing of the
warning light on the instrument panel,
to inform the driver that the vehicle is
in critical stability and grip conditions.
HBA (Hydraulic Brake Assist) SYSTEM
40) 41) 42)
The HBA system is designed to improve
the car’s braking capacity during
emergency braking: the HBA system
therefore completes the ABS system.
Maximum assistance from the HBA
system is obtained by continuously
pressing the brake pedal very quickly.
EBD SYSTEM
The EBD system is an integral part of the
ESC system and intervenes during
braking, distributing the brake force
optimally between front and rear wheels.
This guarantees greater braking stability
for the car, preventing sudden locking of
the rear wheels and the consequent
instability of the car.
DTC (Drag Torque Control) SYSTEM
This is an integral part of the ABS
system and intervenes in the case of
sudden downshifting, or during braking
when the ABS intervenes, restoring
torque to the engine and thus preventing
excessive drag at the drive wheels, which
may lead the wheels to lock and a loss of
car stability, above all in low-grip
conditions.

51
ESC SYSTEM
The ESC system improves the
directional control and stability of the
car in various driving conditions.
The ESC system corrects the car’s
understeer and oversteer, distributing
the brake force on the appropriate
wheels. The torque supplied by the
engine can also be reduced in order to
maintain control of the vehicle.
25) 26) 27) 28) 29)
The ESC system comprises the active
safety systems such as: ABS, EBD, ASR,
HILL HOLDER, etc.
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.
CBC
(Cornering Braking Control) SYSTEM
This system acts when braking on
corners, optimising the distribution of
brake pressure on the four wheels: the
system prevents the wheels on the
inside of the corner (less affected by the
weight of the car) from locking, ensuring
better stability and direction for the car.
HILL HOLDER SYSTEM
This is an integral part of the ESC system
and facilitates starting on uphill or
downhill slopes by operating the brakes:
IMPORTANT The Hill Holder system is
not a parking brake, therefore do not
leave the car without activating the
handbrake, switched the engine off and
engaged first gear, so that the car is
parked in safety conditions (for further
information read paragraph
“When parked” in the chapter “Starting
and driving”).
IMPORTANT There may be situations on
small gradients (less than 8%), with car
laden, in which the Hill Holder system
may not activate thus causing a slight
reversing motion and increasing the risk
of collision with another vehicle or
object. The driver is, in any case,
responsible for safe driving.
“ELECTRONIC Q2” SYSTEM (“E-Q2”)
The DTC 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 this conditions, the engine braking
effect could cause the drive wheels to
slip, resulting in a loss of vehicle stability.
In these situations, the DTC system
intervenes, restoring torque to the
engine in order to conserve vehicle
stability and increase vehicle safety.

SAFETY
52
“PRE-FILL” SYSTEM
(RAB - Ready Alert Brake)
(only with “Dynamic” mode engaged)
This function activates automatically if
the accelerator pedal is released rapidly,
reducing the brake pad travel (both at
front and back), with the aim of preparing
the braking system and enhancing its
responsiveness, thus reducing the
stopping distance in the event of
subsequent braking.
25)The ESC system cannot alter the
natural laws of physics, and cannot
increase grip, which depends on the
condition of the road.
26)The ESC system cannot prevent
accidents, including those due to
excessive speed on corners, driving on
low-grip surfaces or aquaplaning.
27)The capability of the ESC system
must never be tested irresponsibly and
dangerously, in such a way as to
compromise personal safety and the
safety of others.
28)For the correct operation of the ASR
system, 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.
IMPORTANT
29)Do not take unnecessary risks, even if
your vehicle is fitted with the ESC and
ASR systems.
Your driving style must always be suited
to the road conditions, visibility and
traffic.
The driver is always responsible for road
safety.
30)When the ABS intervenes and you
notice the brake pedal pulsating, do not
reduce the pressure, but hold it firmly and
confidently; in doing so you will brake in
the shortest distance possible, depending
on the road conditions.
31)For 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.
32)If the ABS intervenes, this indicates
that the grip of the tyres on the road is
nearing its limit: you must slow down to a
speed compatible with the available grip.
33)The ABS cannot overrule the natural
laws of physics, and cannot increase the
grip available according to the condition
of the road.
34)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.35) 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.
36)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.
37)The ASR cannot overrule the natural
laws of physics, and cannot increase the
grip available according to the condition
of the road.
38)The ASR system cannot prevent
accidents, including those due to
excessive speed on corners, driving on
low-grip surfaces or aquaplaning.
39) The capability of the ASR must never
be tested irresponsibly and dangerously,
in such a way as to compromise personal
safety and the safety of others.
40)The HBA system can’t overrule the
natural laws of physics, and can’t increase
the grip available according to the
condition of the road.
41)The HBA system cannot prevent
accidents, including those due to
excessive speed on corners, driving on
low-grip surfaces or aquaplaning.
42) The capability of the HBA system
must never be tested irresponsibly and
dangerously, in such a way as to
compromise the safety of the driver, the
other occupants of the vehicle or any
other road user.

TPMS
(Tyre Pressure Monitoring
System)
(where provided)
DESCRIPTION
The tyre pressure monitoring system
(TPMS) warns the driver of low tyre
pressure on the basis of the cold
inflation pressure prescribed for the car.
Changes in outside temperature may
cause tyre pressure to vary.
This means that a decrease in the
outside temperature corresponds to a
decrease in the tyre pressure.
The tyre pressure must always be
adjusted according to the cold tyre
inflation pressure.
Cold tyre inflation pressure is the tyre
pressure after letting the car at a
standstill for at least three hours or a
travel shorter than 1.6 km after an
interval of three hours.
The cold tyre inflation pressure must not
exceed the maximum pressure indicated
on the tyre sidewall.Tyre pressure increases also while
driving: this is a normal condition and no
pressure adjustment is needed.
The TPMS continues to advise the driver
of the low tyre pressure condition until
this is corrected; the warning continues
until the pressure corresponds or
exceeds the pressure prescribed for the
cold tyres. When the low tyre pressure
warning light
nappears on the
instrument panel, the inflation pressure
must be adjusted up to the prescribed
cold inflation value.
The tyre pressure warning light switches
off after the system refreshes
automatically. You may need to drive the
car for about 20 minutes at a speed
higher than 20 km/h to allow the TPMS
to receive this information.
NOTE
❒ The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
❒ The TPMS must not be used as a
pressure gauge while adjusting tyre
pressure❒ Driving with low tyre pressure causes
overheating and may cause a fault in the
tyres themselves. The low inflation
pressure reduces fuel efficiency and tyre
tread life and may also affect handling
and braking performance of the car.
❒ The TPMS does not replace the
correct tyre maintenance.
It is up to the driver to maintain the
correct tyre pressure level measuring it
with a suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not cause
the tyre pressure control warning light to
switch on.
❒ The TPMS warns the driver of any
condition of insufficient tyre pressure.
If this drops below the insufficient
pressure limit for any reason including
low temperature and normal pressure
loss of the tyre.
❒ The seasonal temperature changes
affect tyre pressure.
