provided by the driver. This allows faster and more
powerful operation of the braking system.
IMPORTANT When the Mechanical Brake Assist is
activated, noises may be heard from the system. This
is normal. In any case, while braking keep the brake
pedal firmly depressed.
WARNING
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.
WARNING
If the ABS cuts in, it is a sign that the
grip between tyre and the road surface
has reached the limit : you must slow down to
match the speed to the road grip available.
WARNING
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.FAILURE INDICATIONS
ABS failure
ABS failure is indicated by warning light
in the
instrument panel coming on (together with the
appropriate message on the multifunction display on
some versions) (see “Warning lights and messages”).
In this case, the braking system will work as normal,
but without the extra capacity offered by the ABS
system. Drive carefully to the nearest Fiat Dealership
to have the system checked.
EBD failure
ABS failure is indicated by warning light
andin
the instrument panel coming on (together with the
appropriate message on the multifunction display
on some versions) (see “Warning lights and
messages”).
In this case, the rear wheels may suddenly lock and
the vehicle may swerve when braking sharply. Drive
carefully to the nearest Fiat Dealership to have
the system checked.

WARNING
If only warning lightlights up in the
instrument panel (with a message in the
multifunction display on some versions), stop
the vehicle immediately and contact the nearest
Fiat Dealership. Fluid leaking from the
hydraulic system will compromise the operation
of the braking system, whether it is of the
conventional type or with ABS.
ESC (Electronic Stability Control)
SYSTEM
(for versions/markets, where provided)
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
appropriate wheels. The torque supplied by the
engine can also be reduced in order to maintain
control of the vehicle.
The ESC system uses the sensors in the vehicle to
determine the trajectory required by the driver
through steering and compares it with the real
trajectory of the vehicle. When the real trajectory
deviates from the desired trajectory, the ESC system
intervenes to counter the car’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
The ESC system also includes the following systems:
Hill Holder
ASR
MSR
HBA

SYSTEM INTERVENTION
It is signalled by the blinking of the instrument panel
warning light
, to inform the driver that the car
is in critical stability and grip conditions.
Switching the system on
The ESC system is automatically activated when the
vehicle is started and cannot be deactivated.
Failure indications
In the event of a failure, the ESC system will be
automatically switched off and warning light
will
switch on constantly on the instrument panel along
with a message on the multifunction display (for
versions/markets where provided) (see chapter
"Warning lights and messages"). Contact a Fiat
Dealership as soon as possible.
WARNING
The ESC system can’t overrule the
natural laws of physics, and can’t
increase the grip available according to the
condition of the road.
WARNING
The ESC system cannot prevent
accidents, including those due to
excessive speed on corners, driving on low-grip
surfaces or aquaplaning.
WARNING
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.
HILL HOLDER SYSTEM
(for versions/markets, where provided)
This system is an integral part of the ESC system and
facilitates starting on slopes.
It is automatically activated in the following
conditions:
uphill: vehicle stationary on a road with a gradient
higher than 5%, engine running, brake pedal
pressed and gearbox in neutral or gear other than
reverse;
downhill: vehicle stationary on a road with a
gradient higher than 5%, engine running, brake
pedal 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 two seconds have
elapsed, without starting, the system is automatically
deactivated, gradually releasing the braking pressure.
During this release stage, the typical brake
disengagement noise indicating that the vehicle is
going to move imminently will be heard.

Failure indications
Instrument panel warning light
will light up in the
event of a failure (see “Warning lights and
messages”).
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 first gear.
WARNING
For the ESC and ASR systems to function
correctly, all four tyres must be the
same brand and type, must be in excellent
condition and, above all, must be of the
prescribed type and size.
ASR SYSTEM (Anti-Slip Regulation)
(for versions/markets, where provided)
This is a traction control system that cuts in
automatically every time one or both drive wheels
slip.
Depending on how slippery the road is, two different
control systems are activated:
if slipping involves both driving wheels, the ASR
function intervenes reducing the power
transmitted by the engine;
if the slipping only involves one of the drive
wheels, the ASR intervenes automatically braking
the wheel that is slipping.
The action of the ASR system is especially useful in
the following conditions:
slipping of the inner wheel round bends due to
dynamic variations in the load of excessive
acceleration;
excessive power transmitted to the wheels, also in
relation to road surface conditions;
acceleration on slippery, snowy or icy road
surfaces;
in the case of loss of grip on a wet surface
(aquaplaning).
WARNING
For the ESC and ASR systems to function
correctly, all four tyres must be the
same brand and type, must be in excellent
condition and, above all, must be of the
prescribed type and size.
WARNING
The ASR system cannot overrule the
natural laws of physics, and cannot
increase the grip available according to the
condition of the road.

WARNING
The ASR system cannot prevent
accidents, including those due to
excessive speed on corners, driving on low-grip
surfaces or aquaplaning.
WARNING
The capability of the ASR system must
never be tested irresponsibly and
dangerously, in such a way as to compromise
personal safety and the safety of others.
MSR SYSTEM (engine drive regulation)
This is an integral part of the ESC system that, in the
event of a sudden gear down shift or an ABS braking,
cuts in and provides torque to the engine thus
preventing excessive driving wheel drive which,
especially in poor grip conditions, can lead to a loss
of stability.Engagement/ disengagement of the ASR
system
The ASR system switches on automatically each time
the engine is started.
When travelling, the ASR system can be switched off
and on again pressing button fig. 91 located among
the controls in the instrument panel.
Switching off is shown by the warning light
on the
instrument panel switching on together with a
message shown in the multifunction display, for
versions/markets where provided.
If the ASR is switched off when driving, it is
automatically switched on again when the vehicle is
started up.
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.

WARNING
Do not take unnecessary risks, even if
your vehicle is fitted with this system.
Your driving style must always be suited to the
road conditions, visibility and traffic .The driver
is always responsible for road safety.
FAILURE INDICATIONS
In the event of a failure, the ASR system will be
automatically switched off and warning light
will
appear permanently on the instrument panel along
with a message on the multifunction display (for
versions/markets where provided) (see “Warning
lights and messages” section). In this case, contact a
Fiat Dealership as soon as possible.
HYDRAULIC BRAKE ASSIST (assistance
during emergency braking)
(for versions/markets, where provided)
The HBA system is an integral part of the ESC
system and 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 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
The HBA system cannot overrule the
natural laws of physics, and cannot
increase the grip available according to the
condition of the road.
WARNING
The HBA system cannot prevent
accidents, including those due
to excessive speed on corners, driving on
low-grip surfaces or aquaplaning.
WARNING
The capability of the HBA must never
be tested irresponsibly and dangerously,
in such a way as to compromise personal safety
and the safety of others.

iTPMS System (indirect Tyre
Pressure Monitoring System)
(for versions/markets, where provided)
The indirect Tyre Pressure Monitoring System iTPMS
can monitor the tyre inflation status through the
wheel speed sensors. The system warns the driver if
one or more tyres are flat by switching on the
warning light on the instrument panel and
a warning message on the display, along with an
acoustic signal.
If one tyre only is flat, the system can indicate its
position: it is in any case recommended to check the
pressure on all four tyres. This indication is displayed
also when turning the engine off and on until the
“Reset” procedure is carried out.
“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. 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
warning light may give false
indications on one or more tyres.
To carry out the “Reset” procedure, with the vehicle
stopped and the ignition device at MAR, use the
Setup Menu as follows:
briefly press thebutton: the display will show
"Reset";
press thebutton or thebutton to select
("Yes" or "No");
briefly press thebutton: the display will show
"Confirm";
pressbutton orto select ("Yes" to
“Reset” or "No" to exit the video page);
press thebutton again to return to the standard
screen or to the main menu according to where
you are in the menu.
After the “Reset” the display will show the "Reset
saved" message, indicating that the "self-learning" has
been started.

Operating conditions
The system is active for speeds above 15 km/h. 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 Automatic"
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
flashes 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.
WARNING
The system is an aid for the driver, who
must always pay full attention while
driving.The responsibility always rests with the
driver, who must take into account the traffic
conditions in order to drive in complete safety.
The driver must always maintain a safe distance
from the vehicle in front .
WARNING
If the driver depresses the brake pedal
fully or carries out a fast steering during
system operation, the automatic braking
function may stop (e.g. to allow a possible
manoeuvre to avoid the obstacle).
WARNING
The laser beam is not visible at the
naked eye. Do not look directly, or with
optical instruments (e.g. lenses), at the laser
beam from a distance lower than 10 cm: this
may cause damage to the sight .The laser beam
is also present when the key is at MAR but its
operation is off, not available or manually
deactivated with the display Setup Menu.
WARNING
The system intervenes on vehicles
travelling in the same lane. Small sized
vehicles (e.g. bicycles or motorbikes) or people,
animals and things (e.g. pushchairs) and more in
general all those obstacles with a low reflection
of the light emitted by the laser (e.g. vehicles
soiled with mud) are not taken into
consideration.

WARNING
If the car must be placed on a roller
bench (at a speed within 5 and 30 km/h)
for maintenance interventions or if it is washed
in an automatic roller washing tunnel with an
obstacle in the front part (e.g. another car, a
wall or another obstacle), the system may
detect its presence and activate. In this case the
system must be deactivated through the
display Setup Menu.
The laser sensor may have limited or
absent operation due to weather
conditions such as: heavy rain, hail, thick
fog, heavy snow, formation of ice layers on the
windscreen.
Sensor operation may also be
compromised by the presence of dust ,
condensation, dirt or ice on the
windscreen, by traffic conditions (e.g. vehicles
that are driving not aligned with your car, vehicle
driving in a transverse or opposite way on the
same lane, bend with a small radius of curvature),
by road surface conditions and by driving
conditions (e.g. off-road driving). Make sure the
windscreen is always clean. Use specific
detergents and clean cloths to avoid scratching
the windscreen.The sensor operation may also be
limited or absent in some driving, traffic and
road surface conditions.
Projecting loads on the roof of the car
may interfere with the correct operation
of the sensor. Before starting make sure
the load is correctly positioned, in order not to
cover the sensor operating range.
If the windscreen must be replaced due to
scratches, chipping or breakage, contact
exclusively a Fiat Dealership. Do not
replace the windscreen on your own, risk of
malfunction! It is advisable to replace the
windscreen if it is damaged in the laser sensor
area.
Do not tamper nor operate on the laser
sensor. Do not close the openings in the
aesthetic cover located under the interior
rear view mirror. In the event of a sensor failure,
contact a Fiat Dealership.
If you are driving on roads close to trees
with protruding branches it is advisable to
deactivate the system to prevent the
branches at the height of the bonnet or the
windscreen from interfering with the system.

Do not cover the operating range of the
sensor with stickers or other objects.
Also pay attention to other objects on the
bonnet (e.g. a layer of snow) and make sure they
do not interfere with the light emitted by the
laser.
If a trailer or a vehicle is towed the system
must be deactivated with the display
Setup Menu.
If the system signals a loss of pressure on
a specific tyre, it is recommended to
check the pressure on all four tyres.
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 in the best
way over the front axle when one wheel is slipping.
In effect, 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 more grip on the ground.
This function can be activated manually by pressing
button T+ on the side control panel fig. 92 and
operates under 50 km/h. When this speed is
exceeded, it is automatically deactivated (the LED on
the button is still on) and it is reactivated again
when the speed falls below 50 km/h.
