❒lower the bonnet to about 20 cen-
timetres above the engine compart-
ment and then let it drop. Make sure
that the bonnet is closed correctly and
not just in the safety position by trying
to lift it. If it is not perfectly closed, do
not try to press the bonnet lid down
but open it and repeat the procedure.
IMPORTANT Always check that the bon-
net is closed properly to avoid it opening
while the car is travelling.

ESP SYSTEM (Electronic
Stability Program)
(for versions/markets, where provided)
This is an electronic system that controls
car stability in the event of tyre grip loss,
helping to maintain directional control.
The ESP system is therefore particularly
useful when road surface grip changes.
In addition to the ESP system, ASR system
and Hill Holder, the MSR system (adjusting
the engine braking torque) and the HBA
system (improving the braking force dur-
ing emergency braking) are also provided
(for versions/markets, where provided).
SYSTEM INTERVENTION
This is signalled by the flashing of warn-
ing light
áon the instrument panel, to in-
form the driver that the car is in critical
stability and grip conditions.
When the ABS cuts in and
you feel the brake pedal pul-
sating, do not remove your foot, but
keep the pedal pushed down; in do-
ing so you, will stop in the shortest
distance possible under the road con-
ditions at the time.
WARNINGEBD failure
This is indicated by the
>and xwarn-
ing lights on the instrument panel togeth-
er with the dedicated message on the mul-
tifunction display (for versions/markets,
where provided) coming on (see “Warn-
ing lights and messages” section).
In this case, the rear wheels may sudden-
ly lock and the vehicle may swerve when
braking sharply. Drive carefully to the
nearest Fiat Dealership to have the system
checked.
If only the xwarning light
on the instrument panel
lights up (together with a message in
the multifunction display, for ver-
sions/markets, where provided) 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.

SYSTEM ACTIVATION
The ESP system is automatically activat-
ed when the car is started and cannot be
de-activated.
FAILURE INDICATIONS
In the event of a failure, the ESP will be au-
tomatically switched off and the
áwarn-
ing light will come on permanently on the
instrument panel along with a message on
the multifunction display (for versions/
markets, where provided) (see “Warning
lights and messages” section). The LED on
the ASR OFF button will also light up.
Contact a Fiat Dealership as soon as pos-
sible if this happens.
HYDRAULIC BRAKE ASSIST
(integrated ESP emergency
braking assistance)
(for versions/markets, where provided)
This system (which is compulsory) recog-
nises emergency braking according to the
speed of operation of the brake pedal and
provides additional hydraulic braking pres-
sure to support that applied by the driver.
This allows faster and more powerful op-
eration of the braking system.
The Hydraulic Brake Assist is deactivat-
ed on versions equipped with ESP, in the
event of an ESP system failure (indicated
by warning light
áswitching on together
with the message in the multifunctional
display, for versions/markets, where pro-
vided).
Do not take unnecessary
risks, even if your vehicle is
fitted with an ESP system. Your dri-
ving style must always be suited to the
road conditions, visibility and traffic.
The driver is always ultimately re-
sponsible for road safety.
WARNING
HILL HOLDER SYSTEM
This is an integral part of the ESP system,
making hill-starts easier.
It is automatically activated in the follow-
ing conditions:
❒uphill: vehicle stationary on a road with a gradient higher than 5%, engine run-
ning, brake pedal pressed and gearbox
in neutral or gear other than reverse;
❒downhill: vehicle stationary on a roadwith a gradient higher than 5%, engine
running, brake pedal pressed and re-
verse gear engaged.
At pick-up, the ESP system control unit
will maintain the braking pressure at the
wheels until the necessary engine torque
for moving away is reached or, in any case,
for a maximum of 2 seconds in order to
move easily from the brake pedal to the
accelerator pedal. If the vehicle has not departed after this
time, the system will deactivate automat-
ically by gradually releasing the brake
force.
At release, the typical brake disengage-
ment noise indicating that the car is go-
ing to move will be heard.
Failure indications
System failure is indicated by the turning
on of warning light *
on the instrument
panel with digital display and warning light
áon the instrument panel with multi-
function display (for versions/markets,
where provided) (see section “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 se-
lected first gear.
For the correct operation of
the ESP and ASR systems it
is vital that the tyres are the same
type on all the wheels, in perfect con-
dition and, above all, the recom-
mended size.

MSR system
(engine braking regulation)
This is an integral part of the ASR system
that, in case of sudden gear shifting, cuts
in to provide torque to the engine, thus
preventing excessive driving wheel drag
that, especially in poor grip conditions, can
lead to loss of stability.
Switching the system on/off fig. 97
The ASR system switches on automatically
each time the engine is started.
When travelling, the ASR can be switched
off and on again by pressing button Alo-
cated on the dashboard fig. 97. If the system is off, the LED on the button
lights up together with a message shown
on the multifunction display (for versions/
markets, where provided).
If the ASR is switched off when travelling,
it will turn on again automatically the next
time the engine is started.
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
makes it possible to get better traction.
For the correct operation of
the ESP and ASR systems it
is vital that the tyres are the same
type on all the wheels, in perfect con-
dition and, above all, the recom-
mended size.

ASR OFF
F0M0109m
ASR SYSTEM (Anti-slip Regulator)
This function controls car drive and cuts
in automatically every time one or both
driving wheels skid.
Depending on how skiddy the road is,
two different control systems are acti-
vated:
❒if the skidding involves both drivewheels, the ASR function intervenes
by reducing the power transmitted by
the engine;
❒if the skidding involves only one dri-ving wheel, the ASR system cuts in by
automatically braking the wheel that
is sliding.
The ASR system is particularly helpful in
the following circumstances:
❒skidding of the inner wheel when cor- nering due to the effect of dynamic
load changes or excessive acceleration;
❒too much power transmitted to thewheels in relation to the conditions of
the road surface;
❒acceleration on slippery, snowy oricy surfaces;
❒loss of grip on a wet surface (aqua- planing).

Do not take unnecessary
risks, even if your vehicle is

The driver is always responsible for
road safety.
WARNING
For correct operation of the ASR system,
the tyres must be of the same brand and
type on all wheels, in perfect conditions
and, above all, of the type, brand and size
recommended.
FAILURE INDICATIONS
In the event of a failure, the ASR system
will be automatically switched off and
warning light
áwill appear permanently
on the instrument panel along with a mes-
sage on the multifunction display (for ver-
sions/markets, where provided) (see
“Warning lights and messages”). In this
case, contact a Fiat Dealership as soon as
possible.
EOBD SYSTEM
The EOBD (European On Board Diagno-
sis) system allows continuous diagnostics
of the emission-related components of the
car.
It also alerts the driver, by turning on the
Uwarning light on the instrument panel
(together with a relevant message in the
multifunction display, for versions/mar-
kets, where provided) (see “Warning
lights and messages” section), when these
components are no longer in peak con-
dition.
The goal of the system is to:
❒keep the system efficiency under con- trol;
❒warn when a fault causes emissions lev- els to increase;
❒warn of the need to replace non-per-forming components.
The system also has a connector that can
be interfaced with appropriate equipment,
which makes it possible to read the er-
ror codes stored in the control unit, to-
gether with a series of specific parameters
for engine operation and diagnosis. This
check can also be carried out by traffic
authorities. IMPORTANT After resolving the prob-
lem, to check the system completely, Fi-
at Dealerships are obliged to run a bench
test and, if necessary, road tests which
may call for a long journey.
If, when the ignition key is
turned to the MAR position,
the
Uwarning light either
does not come on or, when
driving, it comes on permanently or
flashes (along with a message in the
multifunction display for versions/mar -
kets, where provided), contact a Fiat
Dealership as soon as possible. The
operation of the Uwarning light may
be checked by traffic police using ap-
propriate equipment. Follow the laws
in force in the country where you are
driving.

ELECTRIC
POWER
STEERING SYSTEM
The car is equipped with an electrically
controlled power steering system called
“Dualdrive”, working only with the igni-
tion key at MARand the engine running,
that customises steering force according
to the driving conditions.
ACTIVATION/DEACTIVATION
(CITY function)
To activate/deactivate the function, press
the button on the dashboard.
Activation is indicated by:
❒the word CITYon the instrument
panel (for versions with multifunction
display);
❒the word CITY lit up on the button
after it has been pressed fig. 98.When the CITY
function is on, the steer-
ing wheel effort is lighter, making parking
easier: therefore, this function is particu-
larly useful for driving in city centres.
For the Sport version, this function guar-
antees improved driving comfort because
the accelerator pedal is better calibrated
for gradual acceleration/deceleration.

FAILURE INDICATIONS
Any failure of the electric power steering
system is indicated by instrument panel
warning light
gcoming on together with
a message on the multifunction display (for
versions/markets, where provided) (see
section “Warning lights and messages”).
In the event of electric power steering sys-
tem failure, the car can be driven with me-
chanical steering.
IMPORTANT In some circumstances, fac-
tors independent of the electric power
steering could cause the
gwarning light
in the instrument panel to come on.
In this case, stop the car immediately,
switch off the engine for about 20 seconds
and then restart the car. If the warning
light
gis still on, along with the message
on the multifunction display (for ver-
sions/markets, where provided), contact
a Fiat Dealership. IMPORTANT The steering may become
stiffer during parking manoeuvres that re-
quire a lot of turns of the wheel. This is
normal and is caused by the electric con-
trol motor overheating protection system.
No repairs are needed. The power steer-
ing system will start working properly
again the next time the car is used.
It is absolutely forbidden to
carry out any after-market
operation involving steering system or
steering column modifications (e.g. in-
stallation of anti-theft device) that
could badly affect performance and
safety, invalidate the warranty and
also result in the car failing to com-
ply with regulations.
WARNING
Before servicing the car,
switch off the engine and re-
move the key from the ignition to ac-
tivate the steering lock. This is espe-
cially important when the car wheels
are not touching the ground. If this
is not possible (for example if the key
needs to be turned to MAR or the en-
gine must be running), remove the
main fuse that protects the electric
power steering.

START&STOP SYSTEM
(for versions/markets, where provided)
FOREWORD
The Start&Stop device automatically stops
the engine each time the vehicle is sta-
tionary and starts it again when the driver
wants to move off.
This improves the efficiency of the vehicle
by reducing fuel consumption, the emis-
sion of harmful gases and noise pollution.
The system is activated each time the car
is started.
OPERATING MODES
Engine cut-out mode
With manual transmission
With the vehicle stationary, the engine
cuts out with the gearbox in neutral and
the clutch pedal released. With Dualogic gearbox
(for versions/markets, where provided)
The engine cuts out if the car stops with
the brake pedal pressed.
This condition can be maintained even if
the brake pedal is not pressed, if the gear
lever is in position N.
NB
The engine can be stopped automat-
ically only after a speed of about 10 Km/h
is reached, to prevent the engine from be-
ing repeatedly stopped when driving at
walking pace.
The engine being stopped is signalled by
the warning light fig. 99 on the instrument
panel, depending on the configuration. Engine restarting mode
With normal transmission
Press the clutch pedal to allow the engine
to be restarted.
With Dualogic gearbox
(for versions/markets, where provided)
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 .
