During the use of the space-
saver spare wheel, the ESP
system carries on working. However,
you must remind that the space-saver
spare wheel has dimensions smaller
than the standard tyre and therefore
its grip is reduced as to the other car
tyres.
WARNING
FAILURE INDICATIONS
System failure is indicated by the turning
on of warning light
áon the instrument
panel (together with the message on the
display) (see section “Warning lights and
messages”).
IMPORTANT The Hill Holder system is
not a parking brake. Never get out of the
car without engaging the handbrake,
switching the engine off and engaging the
first gear.
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
ASR SYSTEM
(Antislip Regulation)
It is an integral part of the ESP system, it
controls car drive and cuts in automati-
cally every time one or both driving
wheels slip.
According to slipping conditions, two dif-
ferent control systems are activated:
❒if the slipping involves both the driving
wheels, the ASR function intervenes re-
ducing the power transmitted by the
engine;
❒if the slipping involves only one driving
wheel, the ASR system cuts in auto-
matically braking the wheel that is slip-
ping.
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 conditions
of the road surface;
❒acceleration on slippery, snowy or
frozen surfaces;
❒in the case of loss of grip on a wet sur-
face (aquaplaning).Switching the ASR system on/off
The ASR system switches on automatically
each time the engine is started.
Switching on/off is indicated by the rele-
vant message on the display (see section
“Warning lights and messages”).
The performance of the 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.

DASHBOARD
AND CONTROLS
When using the spare wheel,
the ASR system is excluded
and the warning light
áon the in-
strument panel turns on glowing
steadily (together with the message
on the display) (see section “Warn-
ing lights and messages”).
WARNING
FAILURE INDICATIONS
In the event of malfunctioning, the ASR
system is automatically disconnected and
the warning light
áwill turn on with fixed
light on the instrument panel (together
with the message on the display) (see sec-
tion “Warning lights and messages”). In
this case contact Fiat Dealership as soon
as possible.
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
When travelling ASR can be switched off
and on again by pressing switch ASR OFF
set on the dashboard next to the steer-
ing wheel fig. 101.
When the ASR is switched off this is
shown by the lighting up of the led on the
switch (and by the relevant message on
the display) (see section “Warning lights
and messages”).
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.MSR system (engine braking
torque control)
The car is fitted with a special system, in-
tegral with the ASR system, that in case of
sudden gear shifting, cuts in providing
torque to the engine thus preventing ex-
cessive driving wheel drive that, specially
in poor grip conditions, can lead to loss of
stability.

DASHBOARD
AND CONTROLS
This diagnostic system indicates the pres-
ence of deteriorated components or sys-
tem malfunctioning (see section “Warn-
ing lights and messages”) by the turning on
of the instrument panel warning light U
(together with the message on the dis-
play).
NOTE The car is provided with a diag-
nostic connector that can be interfaced
with appropriate tools, which makes it
possible to read the error codes stored in
the control units, together with a series of
specific parameters for engine operation
and diagnosis. This test can also be per-
formed by traffic controller agents.IMPORTANT: After a servicing operation
at Fiat Dealership aimed to eliminate mal-
functioning connected to the EOBD sys-
tem, in order to check the system thor-
oughly it could be required to run a bench
test and, if necessary, road tests which
may also call for a long journey.EOBD SYSTEM
The European On Board Diagnostic sys-
tem (EOBD), fitted to engine electronic
control units, allows monitoring and warn-
ing of any malfunction to the electronic
systems that could increase exhaust emis-
sions.
The objective is:
❒To keep system efficiency under con-
trol;
❒Warn when a fault causes emission lev-
els to increase;
❒Warn of the need to replace deterio-
rated components.

“DUALDRIVE” ELECTRIC
POWER STEERING
SYSTEM
The car is provided with the electrically
controlled power steering system called
“Dualdrive” working only with ignition key
at MARand engine running, that can be
customised by the driver according to the
driving conditions.
IMPORTANT When turning quickly the
ignition key, power steering full operation
is obtained after 1-2 seconds.
ACTIVATION/DEACTIVATION
(CITY function) (where provided)
To connect/disconnect the CITY func-
tion, press button A-fig. 103set on the
dashboard next to the steering wheel.
Activation of this function is indicated by
the word CITY on the instrument panel
display (on certain versions it is also indi-
cated by the turning on of the CITY warn-
ing light).
When the CITY function is on the steer-
ing wheel effort is lighter and thus parking
operations are easier: therefore this func-
tion is particularly useful for driving in city
centres.FAILURE INDICATIONS
Any failure is indicated by the turning on
of warning light
g, together with the
message on the display (on certain ver-
sions a symbol is displayed) (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.SPORT FUNCTION
(where provided)
The vehicle may be equipped with a sys-
tem that allows a choice between two dri-
ving modes: normal and sports.
Press the SPORT button fig. 104to set
the system for a sporty drive with
prompter acceleration response and stiffer
steering wheel movements for a sportier
feel.
Pressing SPORT button enables the over-
boost function.
This function enables the engine control
unit to reach maximum pressure levels in-
side the turbocharger, depending on the
position of the accelerator pedal and for
a limited time. This enables to achieve an
increased engine torque.
This function is quite useful if maximum
performance is required for a short time
(e.g. overcoming other vehicles).

Acceleration
Accelerating violently increasing the revs
will greatly affect consumption and emis-
sions: to contain fuel consumption accel-
eration should be gradual.
Using the SPORT function, fuel consump-
tion will be slightly higher than the values
stated in paragraph “Fuel consumption” in
this Supplement.
It is absolutely forbidden to
carry out whatever after-
market operation involving steering
system or steering column modifica-
tions (e.g.: installation of anti-theft
device) that could badly affect per-
formance and safety, cause the lapse
of warranty and also result in non-
compliance of the car with homolo-
gation requirements.
WARNING
Always switch the engine off,
remove the key from the
starting device and actuate the steer-
ing lock before carrying out any main-
tenance operation, especially when
the wheels are raised from the
ground. In case this is not possible
(e.g. when the key must be in MAR
position or the engine running), re-
move the electric power steering
main fuse before carrying out any
maintenance operation.
WARNING
When the function is on, the S symbol is
lit on the instrument panel. Press the but-
ton again to turn off the function and re-
store normal steering settings.
IMPORTANT when the SPORT button is
pressed, the function activates after about
5 seconds.
IMPORTANT during acceleration, when
the SPORT function is in use, it is possible
to feel steering judder, which is typical of
this sporty setting.
IMPORTANT The steering may become
slightly stiff following parking manoeuvres
including a great deal of steering. This is
normal and caused by a system to prevent
motor overheating. No servicing is re-
quired. The electric power steering sys-
tem will return to normal operation the
next time the car is used.

TYRE PRESSURE MONITORING SYSTEM (T.P.M.S.)
(where provided)T.P.M.S. cannot indicate sudden tyre pres-
sure drops (e.g.: tyre burst). In this event,
brake the car cautiously and avoid sudden
steering.
Strong radio-frequency disturbances could
inhibit proper TPMS system operation.
This condition will be indicated by the
turning on of warning light nnor symbol
on the instrument panel, together with the
message on the display. This indication will
go off automatically as soon as the radio-
frequency disturbance ceases.
The T.P.M.S. system does
not exempt the driver to
check tyre and spare wheel pressure
at regular intervals (see paragraph
“Wheels” in section “Car mainte-
nance”).
WARNING
The car may be equipped with a Tyre Pres-
sure Monitoring System, which indicates to
the driver the tyre pressure status by two
different indications: “Check tyre pres-
sures” and “Low tyre pressures”. For a de-
tailed description of the two indications,
see the “Warning Lights and Messages” sec-
tion. This system consists of a radio-fre-
quency sensor, installed on each wheel (on
the rim inside the tyre) that sends pressure
information to the control unit.IMPORTANT NOTES
Failure indications will not be stored and
therefore will not be displayed when turn-
ing the engine off and on again. If failure
persists, the control unit will send warn-
ing indications to the instrument panel on-
ly after a few seconds when the car is
moving.
Tyre pressure should be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
hot tyres, do not reduce pressure al-
though it is higher than the prescribed val-
ue but repeat the check when tyres are
cold (see section “Wheels” in section
“Technical Specifications”).

The car must only be filled
with diesel fuel for motor ve-
hicles, in compliance with Eu-
ropean Specification EN590.
The use of other products or mixtures
may irreparably damage the engine
with invalidation of the warranty due
to the damage caused. In the event of
accidentally filling with another type
of fuel, do not start the engine and
empty the tank. If the engine has been
run even for only a very short time, in
addition to the tank, it is also necessary
to drain out the whole fuel circuit.DIESEL ENGINES
If the outside temperature is very low, the
diesel thickens due to the formation of
paraffins and could clog the diesel fuel fil-
ter.
In order to avoid these problems, differ-
ent types of diesel are distributed ac-
cording to the season: summer type, win-
ter type arctic type (mountains/cold ar-
eas).
If refuelling with diesel fuel not suitable for
the current temperature, mix diesel fuel
with TUTELA DIESEL ART additive in the
proportions stated on the can, putting first
the antifreeze in the tank and then the
diesel fuel.
Refuel with local diesel fuel if the car is
used/parked in the mountains or in cold
areas for a long period. In this event you
are recommended to keep an amount of
fuel higher than 50% in the tank.AT THE FILLING
STATION
PETROL ENGINES
Use only unleaded petrol.
To prevent errors, the diameter of the fu-
el tank filler is too small to introduce a lead
petrol pump filler.
Use petrol with a rated octane number
(R.O.N.) not lower than 95.
IMPORTANT An inefficient catalyst leads
to harmful exhaust emissions, thus con-
tributing to air pollution.
IMPORTANT Never use leaded petrol,
even in small amount or in an emergency,
as this would damage the catalyst beyond
repair.REFUELLING
To ensure full tank refuelling, carry out
two top-up operations once the delivery
gun has turned off twice. Avoid further
top-up operations which could cause faults
in the fuel system.

During normal service the
catalyst and the diesel par-
ticulate filter (DPF) reach high tem-
peratures. Do not therefore park the
car over inflammable materials (grass,
dry leaves, pine needles, etc.): fire
hazard.
WARNING
Diesel Particulate Filter clogged
If the warning light hon the instru-
ment panel turns on (together with the
message on the display) refer to section
“Warning lights and messages”. DIESEL PARTICULATE FILTER
(DPF) (where provided)
The Diesel Particulate Filter is a mechan-
ical filter, integral with the exhaust system,
that physically traps particulate present
in the exhaust gases of Diesel engines.
The diesel particular filter has been adopt-
ed to eliminate almost totally particulates
in compliance with current / future law
regulations.
During normal use of the car, the engine
control unit records a set of data (e.g.:
travel time, type of route, temperatures,
etc.) and it will then calculate how much
particulates has been trapped by the filter.
Since this filter physically traps particulates,
it shall be cleaned (reclaimed) at regular
intervals by burning carbon particles. Re-
claiming procedure is controlled auto-
matically by the engine control unit ac-
cording to the filter conditions and the
conditions of use of the car.
During reclaiming the following phenom-
ena could take place: idling slight increase,
fan activation, slight smoke increase, high
exhaust temperatures. These situations
shall not be considered as faults and they
do not affect car performance and envi-
ronment.PROTECTING THE
ENVIRONMENT
The devices for curtailing petrol engine
emissions are the following:
❒three-way catalytic converter;
❒Lambda sensor;
❒fuel evaporation system.
In addition, do not let the engine run, even
for a test, with one or more spark plugs
disconnected.
The devices for curtailing diesel fuel en-
gine emissions are the following:
❒oxidising catalytic converter;
❒exhaust gas recirculation system
(E.G.R.);
❒Lambda sensors;
❒diesel particulate filter (DPF) (where
provided it is fitted instead of the Lamb-
da sensor).
