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 road
with 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,
the tyres must be the same make and
type on all wheels, in perfect condi-
tion and, above all, of the type, make
and size recommended.

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 systemon/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 buttonAlo-
cated on the dashboardfig. 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,
the tyres must be the same make and
type on all wheels, in perfect condi-
tion and, above all, of the type, make
and size recommended.

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 drive
wheels, 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 the
wheels in relation to the conditions of
the road surface;
❒acceleration on slippery, snowy or
icy surfaces;
❒loss of grip on a wet surface (aqua-
planing).

AND DEVICES
Do not take unnecessary
risks, even if your vehicle is
fitted with this system. Your driving
style must always be suited to the

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,
theUwarning 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 theUwarning light may
be checked by traffic police using ap-
propriate equipment. Follow the laws
in force in the country where you are
driving.

STARTING
AND DRIVING
IMPORTANT When snow tyres are used
with a maximum speed index below the
one that can be reached by the car (in-
creased by 5%), place a notice in the pas-
senger compartment, plainly in view, which
states the maximum permissible speed of
the snow tyres (as per an EC Directive).
All four tyres should be the same (brand
and profile) to ensure greater safety when
driving and braking as well as making the
car more responsive.
Remember that you should not change the
rotation direction of the tyres.SNOW CHAINS
The use of snow chains should be in com-
pliance with local regulations.
Snow chains may be fitted only to the
front wheel tyres (drive wheels). Use of
Lineaccessori Fiat snow chains is recom-
mended.
Check the tension of the chains after the
first few metres have been driven.
IMPORTANT When the snow chains are
on, use the accelerator with extreme
care to prevent, or to limit as much as
possible, the driving wheels from skid-
ding. This could cause the chains to
break, resulting in damage to the vehicle
body or mechanical components.
IMPORTANT Use compact 9 mm snow
chains.
SNOW TYRES
Use snow tyres of the same size as the
normal tyres provided with the car.
A Fiat Dealership will be happy to provide
advice concerning the most suitable type
of tyre for the customer’s requirements.
For the type, pressures and specifications
of the snow tyre to be used, follow care-
fully the instructions given in the “Wheels”
paragraph of the “Technical specifications”
section.
The performance of these tyres is con-
siderably reduced when the tread depth
is less than 4 mm. If this is the case, replace
them.
Due to their specific features, the perfor-
mance of snow tyres is much lower than
that of standard tyres in normal condi-
tions or on long motorway stretches. You
should therefore use them only in the
conditions for which they were designed.
The maximum speed for
snow tyres marked “Q” is
160 km/h, while it is 190 km/h for “T”
tyres and 210 km/h for “H” tyres. You
should, however, always stick to the
speed limits of the highway code.
