READ THIS CAREFULLY
REFUELLING
Petrol engines: only refuel with unleaded petrol with octane rating (RON) not less than 95 in compliance with the European specification
EN228. Do not use petrol containing methanol or ethanol E85. Using these mixtures may cause misfiring and driving issues, as well as
damage fundamental components of the supply system.
Diesel engines: refuel only with diesel fuel motor vehicles conforming to the European specification EN590. The use of other products or
mixtures may damage the engine beyond repair and consequently invalidate the warranty, due to the damage caused.
LPG engines: refuel only with LPG for motor vehicles conforming to the European specification EN589. The use of other products or
mixtures may damage the engine beyond repair and consequently invalidate the warranty, due to the damage caused.
Refuelling with methane: refuel only with methane for motor vehicles. The use of other products or mixtures may damage the engine
beyond repair and consequently invalidate the warranty, due to the damage caused.
For further details on the use of the correct fuel see the "Refuelling the car" paragraph in the "Starting and driving" chapter.
STARTING THE ENGINE
Version with manual transmission (petrol engines): make sure that the handbrake is engaged; set the gear lever to neutral; fully depress
the clutch pedal without pressing the accelerator, then turn the ignition key to AVV and release it as soon as the engine has started.
Versions with manual transmission (Diesel engines): make sure that the handbrake is engaged; set the gear lever to neutral, fully
depress the clutch pedal without pressing the accelerator, then turn the ignition key to MAR and wait for the
warning light to switch off.
Turn the ignition key to AVV and release it as soon as the engine has started.
Versions with Dualogic gearbox: make sure that the handbrake is engaged and that the gear lever is in P (Park) or N (Neutral). Then
depress the brake pedal, turn the ignition key to AVV and release it as soon as the engine starts.
PARKING ON FLAMMABLE MATERIAL
The catalytic converter develops high temperatures during operation. Do not park the car on grass, dry leaves, pine needles or other
flammable material: fire hazard.
RESPECTING THE ENVIRONMENT
The vehicle is fitted with a system that carries out a continuous diagnosis of the emission-related components in order to help protect the
environment.
ELECTRICAL ACCESSORIES
If, after buying the vehicle, you decide to add electrical accessories (with the risk of gradually draining the battery), contact a Fiat Dealership.
They can calculate the overall electrical requirement and check that the vehicle's electric system can support the required load.
SCHEDULED SERVICING
Correct maintenance of the car is essential for ensuring that it maintains its performance and its safety features, its environmental friendliness
and low running costs for a long time to come.

WARNING
1)Button B fig. 4should only be pressed
when the key is away from the body, in
particular from the eyes and from objects
that can be spoilt (e.g. clothes). Do not
leave the key unattended to avoid the
button being accidentally pressed while it
is being handled, e.g. by a child.
2)Once the safe lock system is engaged, it
is impossible to open the doors from
inside the car. Therefore, before getting out
of the car check that there is no-one left
on board.
WARNING
1)The electronic components inside the
key may be damaged if the key is
subjected to strong shocks. In order to
ensure complete efficiency of the
electronic devices inside the key, it should
never be exposed to direct sunlight.
WARNING
1)Used batteries should be disposed of,
as specified by law, in the special
containers, otherwise take them to a Fiat
Dealership, which will deal with their
disposal.
IGNITION DEVICE
3) 4) 5) 6)
The key can be turned to three different
positions fig. 6:
STOP: engine off, key can be
removed, steering column locked.
Some electrical devices (e.g. central
door locking system, etc.) can operate;
MAR: driving position. All electrical
devices are enabled;
AVV: engine starting.
The ignition device is fitted with a safety
system that requires the ignition key
to be turned back to STOP if the engine
does not start, before the starting
operation can be repeated.STEERING LOCK
Engagement: when at STOP, remove
the key and turn the steering wheel until
it locks.
Disengagement:move the steering
wheel slightly as you turn the ignition
key to MAR.
WARNING
3)If the ignition device has been tampered
with (e.g. an attempted theft), have it
checked by a Fiat Dealership before driving
again.
4)Always remove the key when you leave
your car to prevent someone from
accidentally operating the controls.
Remember to engage the handbrake.
Engage 1
stgear if the car is parked uphill or
reverse if the car is parked downhill. Never
leave children unattended in the vehicle.
5)It is absolutely forbidden to carry out any
after-market operation involving steering
system or steering column modifications
(e.g.: installation of anti-theft device) that
could badly affect performance and safety,
invalidate the warranty and also result in
non-compliance of the car with type-
approval requirements.
6)Never remove the key while the car is
moving. The steering wheel would
automatically lock as soon as you try to
turn it. This holds true for cars being towed
as well.

KNOWING YOUR CAR

In Italy, the tank has a life of 10 years
starting from the car registration date. If
the vehicle has been registered in a
country other than Italy, the duration
and the testing/inspection procedures
of the LPG tank can vary depending on
the national laws of that country. In all
case, when the time limit for your
country has expired, go to a Fiat Dealer
to have the tank replaced.
SELECTION OF
PETROL/LPG SUPPLY
TYPE
The fig. 55 button (petrol/LPG switch)
allows you to select running on petrol or
LPG.
If, during LPG operation, the same runs
out, the car switches to petrol
automatically and all the bars near the
letters LPG on the display switch off.
This condition persists until the next
LPG refuelling.The engine always starts up on petrol,
with automatic switching to LPG when
the best conditions are achieved
(engine water temperature, minimum
engine rpm limit) for switching to LPG.
REFUELLING
LPG
Maximum refuelling capacity (including
reserve): 38.4 litres. The figure already
takes into account the 80% tank filling
limit and the residual fluid required
for priming; this figure represents the
maximum permitted capacity.In
addition, this value may, in different
refuelling situations, give rise to
variations as a result of: differences
between the supply pressures of
the pumps, pumps with different
supply/stopping specifications,
tank not in reserve condition.
IMPORTANT In order to avoid
inconsistent information by the LPG
gauge on the instrument panel, it is
recommended to refill with at least 10
litres each time.
WARNING
34)Note that in some countries (including
Italy) there are legal restrictions in force
for parking/garaging motor vehicles fuelled
by gas that is denser than air; LPG comes
under this category.
35)Do not switch between the two
operating modes whilst starting the engine.
36)If gas is smelt, switch from LPG
operation to petrol operation and
immediately go to a Fiat Dealership to have
the vehicle checked and possible system
faults excluded.
WARNING
16)The car is equipped with a specifically
designed gaseous LPG injection system:
it is therefore absolutely forbidden to
alter the configuration of the system or its
components. The use of other
components or materials could cause
malfunctions and lead to a reduction
in safety; therefore, in the case of
problems, contact a Fiat Dealership. When
towing or lifting the vehicle, follow the
instructions in the main handbook under
the paragraph on "Towing the vehicle"
to prevent damage to the gas system
parts.
17)The system operates at temperatures
ranging between -20°C and 100°C.

KNOWING YOUR CAR

18)When painting in an oven, the LPG
tank must be removed from the car and
later refitted by a Fiat Dealership. Although
the LPG system has numerous safety
features, it is advisable to proceed
as follows every time the vehicle is not in
use for a long period or moved in an
emergency as a result of a breakdown or
accident: unscrew the devices fastening
the cover of the LPG tank, then remove it.
Close the LPG cock rotating the ring nut
clockwise (see "Passive safety / active
safety"). Refit the cover and retighten the
fastening devices.
19)Only use LPG for motor vehicles.
20)It is strictly forbidden to use any
additive in the LPG. Periodically (at least
once every six months) it is advisable to let
the LPG in the tank run out and, at the
first refuelling, to check that it does not
exceed the maximum capacity of 38.4 litres
(reserve included) (with a tolerance of 2
litres excess). If the level is above 38.4 litres
(reserve included) contact a Fiat
Dealership immediately.
21)When switching is requested, metallic
noise from the valves which pressurise
the circuit can be heard. For the switching
logic described above, a delay between the
valve ticking and the switching off of the
instrument panel indication is completely
normal.22)In particular usage conditions, such as
starting and operation at low ambient
temperature or LPG supply with low
propane content, the system may switch
temporarily to petrol operation, without
a visual indication of switching on the
instrument panel. In the event of low LPG
levels in the tank or request for high
performance (e.g. overtaking, car fully
laden, steep hills) the system may
automatically switch to petrol operation to
guarantee the engine power requested; the
green warning light on the instrument
panel switches on to indicate this. When
the above conditions are no longer
present, the system automatically restores
LPG operation; the green warning light
switches off. To achieve the automatic
switching described above, make sure that
there is always enough fuel in the petrol
tank.VERSION WITH

INTRODUCTION
The "Natural Power" version features
two fuel systems, one for petrol and
one for natural gas (methane).
CYLINDERS
The car is provided with two cylinders
(total capacity approximately 84 litres)
located under the floor (fig. 56 and
fig. 57) and protected by two specific
guards containing compressed
methane in gaseous state (200 bar
nominal pressure at 15°C).

To guarantee switching in full safety, the
actual change to the chosen fuel
system takes place depending on the
car usage conditions; it may not
therefore be immediate.
In addition, when starting at outside
temperatures below approximately
-10°C, the switching times from petrol
to methane increase to allow the
pressure regulator/reduction unit to
heat up.
WARNING
37)The car is equipped with a high-
pressure methane system designed to
operate at 200 rated bar. It is dangerous to
force the system to run at higher
pressures. When towing or lifting the car,
follow the instructions in the "Towing
the car" paragraph to prevent damage to
the methane system parts. If there is a fault
in the methane system, only contact a
Fiat Dealership. Do not modify
configuration or components of the
methane system; they have been designed
exclusively for this car. The use of other
components or materials could cause
malfunctions and prejudice safety.38)When oven painting, the cylinders must
be removed from the vehicle and
subsequently refitted by a Fiat Dealership.
Although the methane system has
numerous safety features, it is advisable to
close the manual cocks for the cylinders
every time the car is not in use for a long
period, transported on other cars or moved
in an emergency as a result of a fault or
accident.
39)Do not switch between the two
operating modes whilst starting the engine.
40)If gas is smelled, switch from methane
operation to petrol operation and
immediately go to a Fiat Dealership to have
the vehicle checked and possible system
faults excluded.
WARNING
23)If, during methane operation, the same
runs out, the car switches to petrol
automatically and all the bars near the
letters CNG on the display switch off. This
display remains until the next methane
refuelling.
24)Regardless of the last fuel system
used, at the following engine starting, after
the initial petrol stage, the system will
automatically switch to methane.
25)When switching from petrol to methane
is requested, a metal noise from the valves
which pressurise the circuit can be heard,
as it happens while starting the car. For the
switching logics described above, a delay
between the valve ticking and the switching
off of the green warning light
is
absolutely normal.26)In particular usage conditions, such as
starting and operation at low ambient
temperature, the system may switch
temporarily to petrol operation, without
indicating the performed switching. In the
event of low methane levels in the tank
or request for high performance (e.g.
overtaking, car fully laden, steep hills) the
system may automatically switch to petrol
operation to guarantee the engine power
requested; the green icon
switches
on to indicate this. When the above
conditions are no longer present, the
system automatically restores methane
operation. The green warning light
turns
off. To achieve the automatic switching
described above, make sure that there is
always enough fuel in the petrol tank.
27)The other plates (provided with the
vehicle documents) show the date when
the first cylinder inspection/test is due.
Methane refuelling stations are not
authorised to refill the cylinders when the
inspection date has expired.

Warning light What it means
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light turns on when the engine is overheated. On some versions the display shows the
dedicated message.
In normal driving conditions: stop the car, switch off the engine and check that the water level in the
reservoir is not below the MIN mark. In this case, wait for the engine to cool down, then slowly and
carefully open the cap, top up with coolant and check that the level is between the MIN and MAX marks on
the reservoir itself. Also check visually for any fluid leaks. If, when restarting, the warning light (or display
symbol) switches on again, contact a Fiat Dealership.
If the car is used under demanding conditions (e.g. in high-performance driving):slow down and, if
the warning light stays on, stop the car. Wait for 2 or 3 minutes with the engine running and slightly
accelerated to further favour the coolant circulation. Then stop the engine. Check that the coolant level is
correct as described above.
IMPORTANT On demanding routes, it is advisable to keep the engine on and slightly accelerated for a few
minutes before stopping it.
53

Warning light What it means
ESC SYSTEM
(for versions/markets, where provided)
The warning light switches on when the ignition key is turned to MAR, but it should switch off after a few
seconds.
ESC system activation
Intervention by the system is indicated by the flashing of the warning light: it indicates that the car is in
critical stability and grip conditions.
ESC system failure
If the warning light does not switch off, or if it stays on with the engine running, a failure was found on the
ESC system. Contact a Fiat Dealership as soon as possible.
Hill Holder failure
The warning light turns on to indicate a Hill Holder system failure. Contact a Fiat Dealership as soon as
possible
ASR SYSTEM DEACTIVATION
The warning light comes on if the ASR system is deactivated (see "Active safety systems" point of the
"Safety" system).
FUEL RESERVE
The warning light comes on when the amount of fuel in the tank is 7.5 litres or less.
IMPORTANT The warning light will flash to indicate a system failure. If this is the case, go to a Fiat
Dealership to have the system checked.
57

Warning light What it means
INJECTION/EOBD SYSTEM FAILURE
The warning light switches on when the ignition key is turned to MAR, but it should switch off after a few
seconds.
If the warning light remains on, or it switches on while driving, the injection system is not working properly.
Warning light constantly on: signals a malfunction in the supply/ignition system which could cause high
exhaust emissions, a possible loss of performance, poor driveability and high consumption. Under these
conditions, the vehicle can continue travelling at moderate speed but without demanding excessive effort
from the engine or high speed. Prolonged use of the car with the warning light on fixed may cause
damage: contact a Fiat Dealership as soon as possible.
The warning light switches off if the malfunction disappears, but is still stored by the system.
Warning light flashing (petrol engines only): signals that the catalytic converter is probably damaged.
Release the accelerator pedal to lower the speed of the engine until the warning light stops flashing.
Continue the journey at moderate speed, trying to avoid driving conditions that may cause further flashing
and contact a Fiat Dealership as soon as possible.
28)
WARNING
28)If, when the ignition key is turned to MAR, the warning light does not switch on, switches on constantly or flashes while driving, contact a
Fiat Dealership as soon as possible. The exhaust emission levels may be checked by the traffic control authorities using the appropriate
equipment. Comply with the laws and regulations of the country where you are driving.
