ESC SYSTEM
(Electronic Stability Control)This is an electronic system that controls car 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 also includes the following
subsystems:
❒Hill Holder
❒ASR
❒HBA
❒DST
❒ERM
SYSTEM INTERVENTION
It is signalled by the flashing of theESCwarning light
on the instrument panel, to inform the driver that
the car is in critical stability and grip conditions.
SYSTEM ACTIVATION
The ESC system switches on automatically when the
engine is started and cannot be switched off.HILL HOLDER SYSTEM
This system is an integral part of the ESC system and
facilitates starting on slopes.
It is activated automatically in the following instances:
❒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 braking pressure on the wheels until the
torque required for starting is reach or, in any case,
for a maximum of 2 seconds so that the right foot
can be moved easily from the brake pedal to the
accelerator pedal.
When 2 seconds have elapsed, without any
departure having taken place, the system is
automatically deactivated, gradually releasing the
braking pressure. During this release stage, a typical
mechanical brake release noise can be heard,
indicating that the car is about to move.
IMPORTANT The Hill Holder system is not a parking
brake; therefore, never leave the vehicle without
having engaged the handbrake, turned the engine off
and engaged the 1
stgear, so that the vehicle is parked
in safe conditions (for further information read
paragraph "When parked" in the chapter "Starting
and driving").

ASR SYSTEM (AntiSlip Regulation)
It is an integral part of the ESC system. It
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.
Activation/deactivation of the ASR system
The ASR system activates automatically each time
the engine is started.
Whilst driving, the ASR can be deactivated and
subsequently activated again by pressing the ASR
OFF button fig. 109.
On some versions, the intervention of the system is
indicated by a message shown on the display.
When the system is deactivated, the LED on the
button ASR OFF turns on and, on some versions, a
message appears on the display.
If the ASR is disengaged during driving, this is
automatically reactivated at the following car starting.
When travelling on snowy roads with snow chains,
it may be helpful to turn the ASR off: in fact, in these
conditions, slipping of the drive wheels when moving
off makes it possible to obtain better traction.
WARNING
For the ESC and ASR systems to operate
correctly, all four tyres must , above all,
be the prescribed brand and type, they must be
in excellent condition and feature the
prescribed type and size.
WARNING
The ESC functions even when the
space-saver wheel is being used. Always
remember that the space-saver wheel, being
smaller than the original wheel, provides less
grip.

WARNING
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.
HBA SYSTEM
(Hydraulic Brake Assist)
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 stopping distance, the HBA
system therefore completes the ABS.
Max. assistance from 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 not necessary anymore.
The HBA system is deactivated when the brake pedal
is released.
WARNING
The HBA system cannot increase tyre
grip on the road over the limits imposed
by laws of physics: always drive carefully
according to the conditions of the road surface.
WARNING
The HBA system cannot prevent
accidents, including those due
to excessive speed on bends, travelling on
low-grip surfaces or aquaplaning.
WARNING
The HBA system is an aid for the driver,
who must always pay full attention
while driving.The responsibility always rests
with the driver.The features of the HBA system
must never be tested in imprudent or dangerous
ways, with the possibility of putting the safety
of the driver, occupants or other road users
at risk.

DST SYSTEM
(Dynamic Steering Torque or steering
corrector)
The DST (steering corrector) function uses the
integration of the ESC system with the electric
power steering to increase the safety level of the
whole car.
In critical situations (understeering, oversteering,
braking 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 brakes and steering
increases the safety and car control feeling.
WARNING
The DST is a driving aid system and does
not replace the driver's actions while
driving the car.ERM ELECTRONIC ROLLOVER
MITIGATION SYSTEM
(Electronic Rollover Mitigation)
The system monitors the raising tendency of the
wheels from the ground if the driver performs
extreme manoeuvres like quick steering to avoid an
obstacle, especially in poor road conditions.
If such conditions occur the system intervenes on
brakes and engine power to reduce the possibility for
the wheels to be raised from the ground.
It is not possible to avoid tendency to roll over if the
phenomenon is due to reasons such as driving on
high side gradients, collision with objects or other
vehicles.
WARNING
The performance of a car with ERM
must never be tested in imprudent
or dangerous ways, with the possibility of
putting the safety of the driver or other people
at risk.

TRACTION PLUS SYSTEM(for versions/markets, where provided)
Traction Plus is a driving aid, useful for setting off in
poor grip conditions (snow, ice, mud, etc.), which
allows the drive force to be distributed optimally on
the front axle.
The activation of the Traction Plus system generates
the differential locking effect on the front axle
through the braking system, to optimise traction on
irregular terrain.
Traction Plus acts by braking the wheels with poor
grip (or those slipping more than the others),
thereby transferring the drive force to those which
have greater grip on the ground.
OPERATION
When the engine is started the system is
deactivated.
To activate the system, press the T+ button fig. 110:
the LED on the button switches on and the display
shows a dedicated message.
The system operates at speeds below 30 km/h: when
this speed is exceeded, it deactivates automatically
(the LED on the button stays on) and reactivates
as soon as the speed drops below 30 km/h.
To deactivate the system, once activated, press the
T+ button again.Traction Plus system fault
If the system is faulty, theESCwarning light on the
instrument panel switches on constantly.

ENGINE STOPPING FAILURE CONDITIONS
When the system is operating, due to comfort,
emission control and safety reasons, the engine does
not stop in some conditions, among which:
❒engine still cold;
❒especially cold outside temperature;
❒battery not sufficiently charged;
❒particulate filter regeneration (DPF) in progress
(diesel engines only);
❒driver's door not shut;
❒driver's seat belt not fastened;
❒reverse gear engaged (for example, for parking
manoeuvres);
❒for versions equipped with automatic climate
control (for versions/markets, where provided), if
an adequate level of thermal comfort has not
been reached or with MAX-DEF mode active;
❒during the first period of use, to initialise the
system.
If climate comfort is to be favoured, the
Start&Stop system can be disabled, for
a continuous operation of the climate
control system.ENGINE RESTARTING CONDITIONS
For reasons of comfort, limiting harmful emissions
and safety purposes, the power unit can restart
automatically without any action on behalf of the
driver if certain conditions are met, including:
❒battery not sufficiently charged;
❒reduced braking system vacuum (e.g. if the brake
pedal is pressed repeatedly);
❒car moving (e.g. when driving on roads with a
gradient);
❒engine stopping by Start&Stop system for over 3
minutes;
❒for versions equipped with automatic climate
control (for versions/markets, where provided), if
an adequate level of thermal comfort has not
been reached or with MAX-DEF mode active.
With gear engaged, automatic engine restarting is
possible only by fully depressing the clutch pedal. The
operation is signalled to the driver with a message
shown on the display.
Notes
If the clutch is not pressed, about 3 minutes after the
engine stops, the engine can be restarted only using
the ignition key.
In cases of unwanted engine stop, due for example to
the clutch pedal being released sharply with a gear
engaged, if the Start&Stop system is active, the
engine can be restarted by fully depressing the clutch
pedal or by placing the gear lever in neutral.

CITY BRAKE CONTROL -
"Collision Mitigation" SYSTEM(for versions/markets, where provided)
This is a driving assistance system that can detect the
presence of cars before the vehicle at a close
distance and, in case of imminent collision,
intervenes automatically braking the car to prevent
the impact or lower its effects.
The system only works if:
❒the ignition key is at MAR-ON;
❒the car speed is between 5 and 30 km/h;
❒the front seat belts are fastened.
The system can be deactivated (and then reactivated)
with the display setup menu (see paragraph “Menu
items” in this chapter).
The system activates if there is risk of imminent
collision and the driver does not press the brake
pedal promptly.
If the system detects that the vehicle ahead could be
hit, it may prepare the car to a possible emergency
braking.
If the driver does not carry out any action to prevent
the collision, the system may automatically slow
down the car, in order to prepare it to a possible
impact.
When there is risk of impact, if the action on the
brake pedal by the driver is not sufficient, the system
may intervene in order to improve the reaction of
the braking system, therefore reducing car speed
further.When driving uphill on a steep slope, the system may
intervene, activating the braking system.
Versions equipped with Start&Stop system:at
the end of the automatic braking, the Start&Stop
system will activate as described in paragraph
"Start&Stop system" of this chapter.
Versions equipped with manual gearbox:atthe
end of the automatic braking the engine may stall
and turn off, unless the driver presses the clutch
pedal.
Versions equipped with Dualogic automatic
transmission(for versions/markets, where
provided): at the end of braking the last gear stored
remains engaged.
IMPORTANT Both on versions equipped with
manual gearbox and on those with automatic
transmission (for versions/markets, where provided),
after the car is stopped the brake calipers may be
stuck for about 2 seconds for safety reasons. Make
sure you press the brake pedal if the car moves
slightly forwards.
IMPORTANT The system is only active with a car
speed between 5 and 30 km/h.
IMPORTANT The system doesNOTactivate
engaging the reverse. The system doesNOTactivate
if the front seat belts are not fastened.
