REFUELLING
Petrol engines: only refuel with unleaded petrol with octane rating (RON) not less than 95.
Diesel engines: only refuel with diesel fuel conforming to the European specification EN590.
Using other products or mixtures may damage the engine beyond repair and cause the forfeiture of the warranty cov-
er for caused damages as a consequence.
ENGINE STARTING
Petrol engines: make sure that the handbrake is engaged; set the gearshift lever to neutral (positions P or N with
automatic transmission); fully depress the clutch pedal (or brake pedal with automatic transmission) without press-
ing the accelerator, then turn the ignition key to START and release it as soon as the engine has started.
Diesel engines: make sure that the handbrake is engaged; set the gearshift lever to neutral (positions P or N with
automatic transmission); fully depress the clutch pedal (or brake pedal with automatic transmission) without press-
ing the accelerator, then turn the ignition key to ON and wait for the
Yand mwarning lights to go off; turn the
ignition key to START and release it as soon as the engine has started.
PARKING ON FLAMMABLE MATERIAL
While working, the catalyst develops a very high temperature. Do not park the car over grass, dry leaves, pine nee-
dles or any other inflammable materials: risk of fire.
RESPECTING THE ENVIRONMENT
The car is fitted with a system that allows continuous diagnosis of the components correlated with emissions to en-
sure better respect for the environment.

THE FIAT CODE SYSTEM
To further protect your car from theft, it
has been fitted with an engine immobilising
system. This system is automatically acti-
vated when the ignition key is removed.
An electronic device, in fact, is fitted in each
ignition key grip. The device transmits a ra-
dio-frequency signal when the engine is
started through a special aerial built into the
ignition switch. The modulate signal, which
changes each time the engine is started, is
the “password”, by means of which the
control unit recognises the key and enables
to start the engine.
OPERATION
Each time the key is fitted into the ignition
switch, the Fiat CODE system control unit
sends a recognition code to the engine con-
trol unit to deactivate the inhibitor.
The code is sent only if the Fiat CODE sys-
tem control unit has recognised the code
transmitted from the key.
Each time the ignition key is removed, the
Fiat CODE system deactivates the func-
tions of the engine electronic control unit.
If the code has not been recognised cor-
rectly, the warning light
Yturns on ac-
companied by the related message on the
display (see chapter “Warning lights and
messages”).
SYMBOLS
Special coloured labels have been attached
near or actually on some of the compo-
nents of your car. These labels bear sym-
bols that remind you of the precautions
to be taken as regards that particular com-
ponent.

ALARM
(where provided)
WHEN THE ALARM
IS TRIGGERED
The alarm comes into action in the fol-
lowing cases:
❒unlawful opening of one of the doors,
bonnet or boot (perimetral protec-
tion);
❒attempt to start the engine with unau-
thorised key;
❒battery cable cutting;
❒presence of moving bodies in the pas-
senger’s compartment (volumetric
protection);
❒abnormal raising/sloping of the car.
Depending on the markets, the cutting in
of the alarm causes operation of the siren
and direction indicators (for about 26 sec-
onds). The ways of operating and the num-
ber of cycles may vary depending on the
markets.
A maximum number of sound/sight cycles
is however envisaged.

AND CONTROLS
Volumetric and anti-raising protections
can be cut off by operating the front ceil-
ing light controls (see paragraphs “Volu-
metric protection sensors” and “Anti-rais-
ing sensor” on the following pages).
IMPORTANT The engine immobiliser
function is guaranteed by the Fiat CODE
system, which is automatically activated
when the ignition key is removed.
HOW TO ACTIVATE
THE ALARM fig. 12
With the doors, bonnet and boot shut and
ignition key to OFFor removed, point
the key with remote control or removed,
point the key with remote control in the
direction of the car, then press and release
the button
Á.
With the exception of certain markets,
the system sounds a “beep” and the doors
are locked.
Engagement of the alarm is preceded by
a self-diagnostic test. If a fault is detected
the system sounds a further warning
“beep” and the display shows the relevant
message (see section “Warning lights and
messages”).
In this case, switch the alarm system off by
pressing button Ë, check that the doors,
bonnet and tailgate are properly shut, then
switch the system on again by pressing
button Á.
fig. 12F0L0100m
If the doors, bonnet and boot are shut
correctly and the warning “beep” is re-
peated, the system self-diagnostics has de-
tected a system operating fault. It is there-
fore necessary to contact a Fiat Dealer-
ship.
IMPORTANT Operating a door with the
metal insert of the key will not activate the
alarm.
IMPORTANT The alarm is built in com-
pliance with the law and regulations of the
different destination countries.

IGNITION SWITCH
The key can be turned to 3 different po-
sitions fig. 17:
❒OFF: engine off, key can be removed,
steering column locked. Certain elec-
trical devices (e.g.: sound system, pow-
er windows…) can work.
❒ON: driving position. All electrical de-
vices are powered.
❒START: engine starting.
The ignition switch is fitted with an elec-
tronic safety system that, in the event the
engine is not started, turns back the igni-
tion key to OFFbefore repeating the
starting operation.
fig. 17F0L0004m
If the ignition device is tam-
pered with (e.g.: attempted
theft), have it checked over by a Fiat
Dealership as soon as possible.
WARNING
When getting out of the car,
always remove the key to
prevent any occupants from acci-
dentally activating the controls. Re-
member to engage the handbrake
and if the car is parked on uphill slope
to engage the first gear. If the car is
facing downhill, engage the reverse
gear (position P with automatic trans-
mission). Never leave unsupervised
children in the car.
WARNING
STEERING COLUMN LOCK
Engaging
The steering column lock will engage 5
seconds after removing the key from the
ignition switch (engine off).
Disengaging
The steering column lock will disengage
after fitting the key into the ignition switch.
IMPORTANT Switching the engine off
when the car is running will not engage the
steering column lock. The multifunction
display will show the relevant message
(see section “Warning lights and Mes-
sages”).
IMPORTANT If, after trying to turn the
instrument panel on and/or to start the
engine, the display will show the message
“Check vehicle protection system”, repeat
the operation rocking the steering wheel
to facilitate steering unlocking. Displaying
of this message does not impair steering
column lock operation.

When the engine is idling, the rev counter
may indicate a gradual or sudden higher-
ing of the speed.
This is normal as it takes place during nor-
mal operation, for example when activat-
ing the climate control system or the fan.
In particular a slow change in the speed
preserves the battery charge.

INSTRUMENTS
REV. COUNTER fig. 18
Rev counter shows engine rpm.
IMPORTANT The electronic injection
control system gradually shuts off the flow
of fuel when the engine is “over-revving”
resulting in a gradual loss of engine pow-
er.
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.

ENGINE COOLANT
TEMPERATURE GAUGE fig. 20
The turning on of the warning light Bin-
dicates that the coolant fluid temperature
is too high; in this case, stop the engine
and contact a Fiat Dealership.
This shows the temperature of the engine
coolant fluid and begins working when the
fluid temperature exceeds approx. 50°C.
Under normal conditions, the needle
should move to different positions of the
scale according to the working conditions
and engine cooling conditions. FUEL LEVEL GAUGE fig. 19
This shows the amount of fuel left in the
fuel tank.
The reserve warning light Aturns on to
indicate that approx. 7 to 9 litres of fuel
are left in the tank.
E- tank empty.
F- tank full (see the indications given in
paragraph “At the filling station").
Do not travel with the fuel tank almost
empty: the gaps in fuel delivery could dam-
age the catalyst.
fig. 19F0L0006m
IMPORTANT If the needle sets at the bot-
tom of the scale (low temperature) with
warning light Bon, it means that the sys-
tem is malfunctioning. Contact a Fiat Deal-
ership to have the system inspected.
