ESP SYSTEM ACTIVATION
The ESP system is automatically activat-
ed when the vehicle is started and cannot
be de-activated.
FAILURE INDICATIONS
In the event of failure, the ESP system is
automatically disconnected, the warning
light
á, comes on with fixed light on the
instrument panel, together with the mes-
sage on the multifunction display (where
provided) (see section “Warning lights and
messages”) and with the button led ASR.
In this case contact a Fiat Dealership as
soon as possible.
Performance of the ESP sys-
tem, in terms of active safe-
ty should not induce the driver to take
pointless and unnecessary risks. The
style of driving must in any case al-
ways be adapted to the conditions of
the road surface, visibility and traffic.
Road safety is always the driver’s re-
sponsibility.
WARNING
HILL HOLDER SYSTEM
This system is an integral part of the ESP
system and it is provided to facilitate start-
ing on slopes.
It will activate automatically with the fol-
lowing conditions:
❒uphill: vehicle at a standstill on a road
with a gradient higher than 5%, engine
running, clutch and brake pedal
pressed, gearbox to neutral or en-
gaged gear other than reverse.
❒downhill: vehicle at a standstill on a
road with a gradient higher than 5%,
engine running, clutch and brake ped-
al pressed and reverse gear engaged.
At pickup the ESP system control unit will
keep brake force on wheels until reaching
the torque suitable for starting, or in any
case for max. 2 seconds in order to pass
easily from the brake pedal to the accel-
erator pedal.
After two seconds without starting, the
system will deactivate automatically by re-
leasing gradually the brake force.
At releasing, the typical brake disengage-
ment noise indicating that the vehicle is
going to move will be heard.Failure indications
System failure is indicated by the turning
on of warning light
á(see section “Warn-
ing 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 en-
gaged the first speed.
For correct operation of the
ESP and ASR systems, the
tyres must absolutely be of the same
brand and type on all wheels, in per-
fect conditions and, above all, of
type, brand and size specified.

MSR system
(engine braking torque control)
It is an integral part of the ASR system that
in case of sudden gear shifting, cuts in pro-
viding torque to the engine thus prevent-
ing excessive driving wheel drive that, spe-
cially in poor grip conditions, can lead to
loss of stability.
Switching the systemon/off fig. 126
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 switch Alo-
cated on the dashboard fig. 126. When the ASR is switched off this is
shown by the lighting up of the led on the
switch and by relevant message on the
multifunction display, where provided.
Versions equipped with ASR system on-
ly, at deactivation (ASR OFF) the warn-
ing light Vwill always stay on.
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, slip-
ping of the driving wheels when moving off
makes it possible to obtain better drive.
For correct operation of the
ESP and ASR systems, the
tyres must absolutely be of the same
brand and type on all wheels, in per-
fect conditions and, above all, of
type, brand and size specified.
WARNING
fig. 126F0N0077m
ASR SYSTEM (Antislip Regulator)
The ASR function controls vehicle drive
and cuts in automatically every time one
or both driving wheels slip.
According to slipping conditions, two dif-
ferent control systems are activated:
❒if slipping involves both driving wheels,
the ASR function intervenes reducing
the power transmitted by the engine;
❒if the slipping involves only one dri-
ving wheel, the ASR system cuts in au-
tomatically braking the wheel that is
slipping.
The action of the ASR is particularly help-
ful in the following circumstances:
❒slipping of the inner wheel due to the
effect of dynamic load changes or ex-
cessive acceleration;
❒too much power transmitted to the
wheels also in relation to the condi-
tions of the road surface;
❒acceleration on slippery, snowy or
frozen surfaces;
❒in the case of loss of grip on a wet sur-
face (aquaplaning).

For correct operation of the ASR system,
the tyres must absolutely be of the same
brand and type on all wheels, in perfect
conditions and, above all, of type, brand
and size specified.
FAILURE INDICATIONS
In the event of failure, the ASR system is
automatically disconnected, the warning
light
á, comes on with fixed light on the
instrument panel, together with the mes-
sage on the multifunction display (where
provided) (see section “Warning lights and

In this case contact a Fiat Dealership as
soon as possible.
EOBD SYSTEM
The EOBD system (European On Board
Diagnosis) allows continuous diagnosis of
the components of the vehicle correlat-
ed with emissions.
It also alerts the driver, by turning on the
warning light
Uon the instrument panel
(together with relevant message on the
multifunction display, where provided)
(see section “Warning lights and mes-
sages”), when these conditions are no
longer in peak conditions.
The objective is:
❒to keep the system efficiency under
control;
❒warn when a fault causes emissions
levels to increase;
❒warn of the need to replace deterio-
rated components.
The system also has a diagnostic connec-
tor that can be interfaced with appropri-
ate tools, which makes it possible to read
the error codes stored in the control unit,
together with a series of specific parame-
ters for engine operation and diagnosis.
This check can also be carried out by the
traffic police.IMPORTANT After eliminating the in-
convenience, to check the system com-
pletely, Fiat Dealerships are obliged to run
a bench test and, if necessary, road tests
which may also call for a long journey.
If turning the ignition key to
MAR, the warning light
Udoes not turn on or if, while
travelling it turns on glowing
steadily or flashing (together with the
message on the multifunction display,
where provided), contact Fiat Dealer-
ship as soon as possible. Warning light
Uoperation can be checked by means
of special equipment by traffic agents.
Always comply with the traffic regula-
tions in force in the country where you
are travelling.

CORRECT USE
OF THE VEHICLE
IMPORTANT When snow tyres are used
with a max speed index below the one
that can be reached by the vehicle (in-
creased by 5%), place a notice in the pas-
senger’s compartment, plainly in the dri-
ver’s view which states the max permis-
sible speed of the snow tyres (as per EC
Directive).
All four tyres should be the same (brand
and track) to ensure greater safety when
driving and braking and better driveability.
Remember that it is inappropriate to
change the direction of rotation of tyres.SNOW CHAINS
Use of snow chains should be in compli-
ance with local regulations.
Snow chains should only be applied to the
driving wheels (front wheels). We rec-
ommend using Lineaccessori Fiat snow
chains.
Check the tension of the chains after the
first few metres have been driven.
IMPORTANT With snow chains, use the
accelerator with extreme care to prevent
or to limit as much as possible slipping of
the driving wheels that could cause chain
breaking resulting in damages to the ve-
hicle body or mechanical components.
IMPORTANT Use snow chains with re-
duced size.
SNOW TYRES
Fiat Dealership will be happy to provide
advice concerning the most suitable type
of tyre for the customer’s requirements.
The winter features of these tyres are re-
duced considerably when the tread depth
is below 4 mm. In this case, they should
be replaced.
Due to the snow tyre features, under nor-
mal conditions of use or on long motor-
way journeys, the performance of these
tyres is lower than that of normal tyres. It
is therefore necessary to limit their use to
the purposes for which they are certified.
The max speed for snow
tyres with “Q” marking is
160 km/h; 190 km/h for tyres with “T”
marking and 210 km/h for tyres with
H marking. The Road Traffic Code
speed limits must however be always
strictly observed.
