ACTIVE SAFETY
SYSTEMS
The vehicle has the following active
safety systems:
ABS (Anti-lock Braking System);
DTC (Drag Torque Control);
ESC (Electronic Stability Control);
TC (Traction Control);
PBA (Panic Brake Assist);
HHC (Hill Hold Control);
DST (Dynamic Steering Torque);
ERM (Electronic Rollover Mitigation);
TSC (Trailer Sway Control).
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 and 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 andstability of the vehicle when braking on
a surface where the grip 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.
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.
31) 32) 33) 34) 35) 36) 37)
DTC (Drag Torque
Control) SYSTEM
The DTC (Drag Torque Control) 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 car
stability. In these situations, the DTC
system intervenes, restoring torque to
the engine in order to conserve car
stability and increase car safety.
ESC (Electronic Stability
Control) SYSTEM
The ESC system improves the
directional control and stability of the
vehicle in various driving conditions.
The ESC system corrects the vehicle’s
understeer and oversteer, distributing
the brake force on the wheels
appropriately. The torque supplied by
the engine can also be reduced in order
to maintain control of the vehicle.
The ESC system uses sensors installed
on the vehicle to determine the
trajectory that the driver intends to
follow and compares it with the
vehicle’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 vehicle is
turning more than it should according
to the angle of the steering wheel.
Understeer: occurs when the vehicle
is turning less than it should according
to the angle of the steering wheel.

System intervention
The intervention of the system 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.
38) 39) 40) 41) 42)
TC (Traction Control)
SYSTEM
The system automatically operates in
the event of slipping, loss of grip on wet
roads (aquaplaning) and acceleration on
slippery, snowy or icy roads, etc. on
one or more drive wheels. Depending
on the slipping conditions, two different
control systems are activated:
if the slipping involves both drive
wheels, the system intervenes, reducing
the power transmitted by the engine;
if the slipping only involves one of the
drive wheels, the BLD (Brake Limited
Differential) function is activated,
automatically braking the wheel which
is slipping (the behaviour of a
self-locking differential is simulated).
This will increase the engine torque
transferred to the wheel which isn't
slipping. This function remains active
even if the "Systems partially disabled"
and "Systems disabled" modes are
selected (see description in the
following pages).System intervention
The intervention of the system 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.
43) 44) 45) 46) 47)
PBA (Panic Brake
Assist) SYSTEM
The PBA system is designed to improve
the vehicle’s braking capacity during
emergency braking.
The system detects emergency braking
by monitoring the speed and force with
which the brake pedal is pressed, and
consequently applies the optimal brake
pressure. This can reduce the braking
distance: the PBA system therefore
completes the ABS.
Maximum assistance from the PBA
system is obtained by pressing the
brake pedal very quickly. In addition, the
brake pedal should be pressed
continuously during braking, avoiding
intermittent presses, to get the most
out of the system. Do not reduce
pressure on the brake pedal until
braking is not necessary anymore.
The PBA system is deactivated when
the brake pedal is released.
48) 49) 50)
HHC (Hill Hold Control)
SYSTEM
This is an integral part of the ESC
system and facilitates starting on
slopes, activating automatically in the
following cases:
uphill: vehicle stationary on a road
with a gradient higher than 5%, engine
running, brake pressed and
transmission in neutral or gear other
than reverse engaged;
downhill: vehicle 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 two seconds have elapsed,
without starting, the system is
automatically deactivated, gradually
releasing the braking pressure. During
this release stage it is possible to hear a
typical mechanical brake release noise,
indicating the imminent movement of
the vehicle.

72
SAFETY

DST SYSTEM (Dynamic
Steering Torque)
The DST function uses the integration
of the ESC system with the electric
power steering to increase the safety
level of the whole vehicle.
In critical situations (braking on surfaces
with different grip conditions), through
the DST function the ESC system
controls the steering to implement an
additional torque contribution on the
steering wheel, to suggest the most
correct manoeuvre to the driver.
The coordinated action of the brakes
and steering increases the sensation of
safety and control of the vehicle.
53)
ERM (Electronic Rollover
Mitigation) SYSTEM
The system monitors the tendency of
the wheels to rise from the ground if the
driver performs extreme manoeuvres
like quick steering to avoid an obstacle,
especially in poor road conditions.
If these conditions occur, the system
intervenes on the brakes and engine
power to reduce the possibility that the
wheels are raised from the ground. It is
not possible to avoid tendency to roll
over if the phenomenon is due toreasons such as driving on high side
gradients, collision with objects or other
vehicles.
54)
TSC (Trailer Sway
Control) SYSTEM
The system employs a series of sensors
located on the vehicle to identify
excessive swerving of the trailer and
take the necessary precautions to
eliminate it.
To counteract the effect of trailer sway,
the system can reduce the engine
power and intervene on the wheels
involved. The TSC system activates
automatically once excessive sway of
the trailer is detected.
System intervention
When the system is active, the
warning light flashes on the
instrument panel, the engine power is
reduced and braking can be felt on the
individual wheels, following the attempt
to eliminate the swerving of the trailer.
55) 56)
WARNING
31)When the ABS intervenes and you feel
the brake pedal pulsating, do not reduce
the pressure, but hold it down firmly and
confidently; in doing so you will brake in the
shortest distance possible, depending on
the current road conditions.
32)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.
33)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.
34)The ABS cannot overrule the natural
laws of physics, and cannot increase the
grip available according to the condition of
the road.
35)The ABS cannot prevent accidents,
including those due to excessive speed on
corners, driving on low-grip surfaces or
aquaplaning.
36)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.
37)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.
38)The ESC system cannot alter the
natural laws of physics, and cannot
increase grip, which depends on the
condition of the road.

DRIVE MODE
The device allows the driver to
select three different driving
modes (car response) according to their
needs and to the road and traffic
conditions, by manually adjusting the
central tunnel knob ring nut A fig. 104.
- "Auto" mode
- "Traction" mode (4x4 or
4x2 versions depending on the trim
level)
- "All Weather" mode (only
4x2 versions depending on the trim
level)
- "Sport" mode.The device, through the on-board
electronic system, operates on the
dynamic control systems of the car:
engine, steering, ESC system,
4x4 system (if available),
gearbox/transmission, and is interfaced
with the instrument panel.
The rotating ring nut is monostable
type. In other words, it always returns
to the central position when released.
The acceptance by the system of the
requested driving mode is signalled by
the LED, located besides the symbol,
coming on, and by the corresponding
symbol appearing on the instrument
panel display.
When the engine is started, the system
usually maintains the driving mode that
was active before the engine was
stopped. For versions/markets where
provided, on start-up, the system is set
to the "Auto" mode.
"Auto" MODE
Recommended mode for normal
driving, aimed at comfort and safety in
normal grip and driving conditions. On
4x4 versions, this mode also reduces
fuel consumption, since it automatically
disconnects the transmission from the
rear wheels if the road and driving
conditions allow it, in addition to
changing drive torque distribution
between the front and rear axles.
Activation
Starting from the active "Traction/All
Weather" mode, turn the ring nut
anticlockwise, keeping it in this position
for at least half a second, and in any
case until the relevant LED turns on,
and the selected mode is shown on the
display. The LED for the previously set
mode will simultaneously turn off. Upon
release, the ring nut will return to the
central position.
Starting from the active "Sport" mode,
turn the ring nut clockwise, keeping it in
this position for at least half a second,
and in any case until the relevant LED
turns on, and the selected mode is
shown on the display. The LED for the
previously set mode will simultaneously
turn off. Upon release, the ring nut will
return to the central position.

MOOD SELECTOR/

LANE ASSIST
SYSTEM (lane
crossing warning)
DESCRIPTION
57) 58) 59) 60) 61) 62)
The Lane Assist system makes use of a
camera located on the windscreen to
detect the lane limits and calculate the
position of the vehicle within such limits,
in order to make sure that it remains
inside the lane.
When both limits of the lane are
detected and the vehicle crosses one of
them without the awareness of the
driver (direction indicator off), the Lane
Assist system provides a tactile warning
by applying torque to the steering wheel
(vibration), thus advising the driver that
he must take an action to remain in the
lane.
IMPORTANT The torque applied to the
steering wheel by the system is
sufficient for the driver to notice it, but
always limited, so that they can easily
override it, and the driver always
maintains control of the vehicle. The
driver can therefore turn the steering
wheel as required at all times.
If the vehicle continues going beyond
the line of the lane without anyintervention from the driver, the
warning light (or the icon on the
display) will be displayed on the
instrument panel to urge the driver to
bring the vehicle back into the limits of
the lane.
IMPORTANT The system monitors the
presence of the driver's hands on the
steering wheel. If they are not detected,
the system emits an acoustic signal and
deactivates until it is reactivated by
pressing the dedicated button (see
description below).
When one limit of the lane is detected
and the vehicle crosses it (direction
indicator off), warning light
(or the
icon on the display) will be displayed on
the instrument panel to urge the driver
to bring the vehicle back into the lane.
In this case, the tactile warning
(vibration on the steering wheel) is not
provided.
SYSTEM ACTIVATION/
DEACTIVATION
The Lane Assist system can be
enabled/disabled using button A
fig. 106, located on the left stalk.Each time the engine is started, the
system keeps the activation status
there was when it was previously
switched off.
On some versions, a dedicated
message appears on the display when
it is activated and deactivated.
Activation conditions
Once switched on, the system
becomes active only if the following
conditions are met:
the driver always keeps at least one
hand on the steering wheel;
vehicle speed ranges between
60 km/h and 180 km/h;
the lane limit lines are perfectly visible
on both sides;
there are suitable visibility conditions;
the road is straight or with wide
radius bends;
