ESC (Electronic
Stability Control)
system 15)
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 also includes the
following subsystems:
❒ HH (Hill Holder): it activates
automatically when starting with car
stationary, on a road with a
gradient higher than 5%.
❒ ASR (AntiSpin Regulation):
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 both drive
wheels.
The ASR comes on automatically
whenever the engine is started. When
driving it is possible to deactivate and
then reactivate the ASR system by
pressing the button A fig. 50: the
system activation is signalled by the
LED on the same button switching on
and, on some versions, by a message
on the display.
❒ HBA (Hydraulic Brake Assist): it
operates automatically and
improves the braking capacity of the
vehicle during emergency braking.
50DVDF0S0151c
SYSTEM INTERVENTION
It is signalled by the blinking of the
warning light
Ion 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.

iTPMS System
(indirect Tyre
Pressure
Monitoring System)
(for versions/markets, where provided)
48)
RESET PROCEDURE
The iTPMS needs an initial “self-
learning” phase (with length depending
on the driving style and road
conditions: optimal conditions being
driving on a straight road at 80 km/h
for at least 20 minutes) which starts
when the Reset procedure is carried
out.
The Reset procedure must be carried
out:
❒ each time tyre pressure is
modified;
❒ when even only one tyre is
changed;
❒ when tyres are rotated/inverted;
❒ when the space-saver wheel is
fitted.
In a few situations such as sporty
driving, particular conditions of the
road surface (e.g. icy, snowy,
unsurfaced roads...) the signalling may
be delayed or partial in detecting the
contemporary deflation of more than
one tyre.
Under special conditions (e.g. vehicle
loaded asymmetrically on one side,
towing a trailer, damaged or worn tyre,
fitting the space-saver wheel, use of
the “Fix&Go” quick tyre repair kit,
fitting snow chains, fitting different
tyres on the axles) the system may
give false indications or be temporarily
deactivated.
If the system is temporarily
deactivated, the warning light
nflashes for about 75 seconds and then
is continuously on; at the same time,
the display shows a dedicated
message.
This indication is displayed also after
the engine has been switched off and
then on again if the correct operating
conditions are not restored. Before carrying out the “Reset”
procedure, inflate the tyres to the
rated pressure values specified in the
inflation pressure table (see “Wheels”
paragraph in the “Technical
specifications” chapter).
If the Reset procedure is not carried
out, in all above cases, the
nwarning light may give false indications
on one or more tyres.
To carry out the Reset procedure, with
the vehicle stopped and the ignition
key at MAR, use the setup menu (see
the description of the “Display”
paragraph). At the end of the Reset
procedure the display will show the
“Reset saved” message, indicating
that the self-learning has been started.
If the iTPMS self-learning is not
correctly executed, the message is not
displayed.
OPERATING
CONDITIONS
The system is active for speeds above
15 km/h.

FUEL CUT-OFF
SYSTEM 8)
This intervenes in the case of an
impact causing:
❒ the fuel supply cut-off with the
engine consequently switching off
❒ automatically unlocking the doors
❒ switching on of all interior lights.
The intervention of the system is
indicated by a message shown on the
display.
IMPORTANT Carefully check the car
for fuel leaks, for instance in the engine
compartment, under the car or near
the tank area.
After a collision, turn the ignition key to
the STOP position to avoid draining the
battery.
To reset car operation, follow this
procedure:
❒ turn the ignition key to MAR
❒ activate the right direction indicator
❒ deactivate the right direction
indicator
❒ activate the left direction indicator
❒ deactivate the left direction indicator
❒ activate the right direction indicator
❒ deactivate the right direction
indicator
❒ activate the left direction indicator
❒ deactivate the left direction indicator
❒ ignition key turned to the OFF
position
❒ turn the ignition key to MAR.PARKING SENSORS
18) 25
(for versions/markets, where provided)
Located in the rear bumper fig. 51
these detect and inform the driver,
through an intermittent acoustic signal,
of the presence of obstacles at the rear
of the car.
As the distance from the obstacle
behind the car decreases, the acoustic
alarm becomes more frequent. The
buzzer becomes continuous when the
distance separating the vehicle from
the obstacle is less than about 30 cm.
It remains constant if the distance
between the vehicle and the obstacle
is unchanged.
If this situation concerns the side
sensors, the signal will stop after
approximately 3 seconds to avoid, for
example, indications in the event of
manoeuvres along a wall.
If several obstacles are detected by the
sensors, only the nearest one is
considered.

53
START&STOP
SYSTEM 19)
The Start&Stop device automatically
stops the engine each time the vehicle
is stationary and starts it again when
the driver wants to move off.
In this way, the vehicle efficiency is
increased, by reducing consumption,
dangerous gas emissions and sound
pollution.
OPERATING MODE
Stopping the engine
❒ With manual gearbox:with the
car stationary, the engine stops with
the gearbox in neutral and the
clutch pedal released.
❒ With Dualogic gearbox:the
engine stops if the vehicle is at a
standstill and the brake pedal is
pressed. This condition can be
maintained even if the brake pedal
is not depressed, if the gear lever is
in position N.
NOTE: The engine can only be
stopped automatically after exceeding
about 10 km/h, to prevent the engine
from being repeatedly stopped when
driving at walking pace.
❒ The warning light
Uon the
instrument panel indicates that the
engine has stopped, on some
versions this indication is given by
the display.
Restarting the engine
❒ with manual gearbox:press the
clutch pedal.
❒ With Dualogic gearbox:if the gear
lever is in position N, place it in any
other gear, otherwise release the
brake pedal or move the gear lever
to +, – or R.
MANUAL ACTIVATION

❒ The Start&Stop system can be
activated/deactivated using the
button
A - fig. 53 on the dashboard.
When the system is deactivated, the
warning light
or
Tsymbol switches on.
❒ On some versions the information is
given by the display.
