PAPER FILTER
The filter fig. 5, located on the pressure
regulator outlet pipe, has the task of fil-
tering the LPG in a gaseous state during
the LPG injectors supply stage.

LPG INJECTORS
There are four injectors fig. 6, specially
designed for LPG, mounted on a special
bracket on the cylinder head and connec-
ted, by means of dedicated pipes, to the
individual intake ducts; they are supplied
with LPG in a gaseous state at a constant
pressure and are operated by a dedicated
electronic control unit.
A gas pressure and temperature sensor
mounted on the injectors sends an elec-
trical signal to determine the LPG injec-
tion time.

ELECTRONIC CONTROL
UNIT
The car has a dedicated electronic control
unit for the LPG system fig. 7; it uses the
incoming signals from the petrol injection
control unit and converts them into signals
for the injection of the LPG.
The control unit for the injectors has the
same strategy as the petrol control unit
(timed, sequential, multipoint).
LPG/PETROL SWITCH
The LPG/petrol switch fig. 8is located on
the central console near the handbrake
and includes:
A. LPG/petrol operating mode request
button;
B. LPG gauge: 5 LEDs (4 green and 1 red
to indicate the reserve). The red LED only
comes on when the last green LED goes
out.
The red LED indicates the reserve status;
ON. LPG operating mode indicator: green
LED on continuously, located under but-
tonA;
OFF. petrol operating mode indicator:
amber LED on continuously, located abo-
ve buttonA.
IMPORTANT When the ignition key is
turned to the MAR – ONposition, the
LEDs on the switch come on as follows:
– with petrol operation mode selec-
ted: amber OFFLED on;
– with LPG operation mode selected:
all LEDs on the switch are on continuou-
sly and the green ONLED flashes.
To select the type of fuel system desired
(LPG or petrol), press button A-fig. 8.
To change the type of fuel system, it is ad-
visable to operate the button with the car
stationary and the engine running or, whil-st driving, after having released the acce-
lerator.
If switching takes place during acceleration
or pick-up, there may be a brief flat spot
(drop in power).
Do not switch between the two operating
modes when starting the engine.

SWITCHING FROM PETROL
TO LPG
With petrol fuel supply: press the button
A-fig 8, the switch to LPG will take pla-
ce automatically at the first significant ac-
celeration.
During switching:
– the LPG gauge Bcomes on;
– the amber OFFLED goes out (petrol
operating mode);
– the green ONLED comes on, switching
from intermittent to on constantly (LPG
operating mode);
There are 5 LEDs B(1 red and 4 green)
on the left of the switch that display the
amount of LPG in the tank.
When the amount of LPG remaining goes
below about 1/5 of the capacity of the
tank, only the red (reserve) LED remains
on to signal the need for refuelling.
IMPORTANT When starting up at outsi-
de temperatures of below −10
°C, the
switching times from petrol to LPG in-
crease to allow the pressure regulator to
heat up.Running out of LPG
If the LPG runs out, switching to petrol
takes place automatically with:
– the amber OFFLED on constantly;
– the green ONLED flashing;
– an acoustic signal from the switch (high
frequency).
IMPORTANT The acoustic signal warns
the driver that the engine is running on pe-
trol; therefore, they must refuel with LPG
before it runs out.
THE acoustic signal can be deactivated by
pressing the switching button A.
Do not switch between the
two operating modes whilst
starting the engine.
Switching from LPG to petrol
With LPG supply: press the buttonA-fig.8.
During switching:
– the LPG gauge Bgoes out;
– the amber OFF LED comes on and
stays on (petrol operating mode);
– the green ONLED goes out (LPG ope-
rating mode).

FUEL CUT-OFF SYSTEM
In the event of an impact to the car, the
petrol and injection supply is cut off im-
mediately, causing the engine to cut out
and, as a result, the LPG safety solenoid
valves to close.
For further information, see the “Fuel cut-
off system” paragraph in the “Controls”
chapter in the Owner Handbook.
STARTING THE ENGINE
The engine is always started on petrol
even with the switch in the LPG position
(green LED flashing, amber LED on con-
stantly), and switches from petrol to LPG
automatically soon after.
There must therefore always be some pe-
trol in the tank to protect the petrol
pump.
To carry out the starting manoeuvre cor-
rectly, see the warnings and advice in the
“Starting the engine” chapter of the Ow-
ner Handbook.
In this situation, you can con-
tinue driving, with the car run-
ning on petrol (excluding the
LPG fuel system). To turn off
the acoustic signal, press button A: the
green ON LED will go out and the am-
ber OFF LED will remain on constan-
tly. Go to a Fiat Dealership as soon as
possible to have the system checked.
SYSTEM FAILURE SIGNALLING
The car has a self-diagnosis system capa-
ble of signalling any malfunctions in the
LPG fuel system through the green ON
LED fig. 8flashing. In the case of faults
that could affect the correct operation of
the engine, the LPG control unit will au-
tomatically switch from LPG operation to
petrol.
This condition will be shown by:
– the amber OFFLED on constantly;
– the green ONLED flashing;
– an acoustic signal from the switch (low
frequency).

REFUELLING THE CAR
LPG FILLER CAP
The gas filler is located next to the petrol
filler cap. It has a one-way valve, located
in the actual filler body.
To access the filler B-fig. 9, open the ac-
cess flap Aand undo the cap C.
Observe the following precautions during
the refuelling operation:
– switch off the engine;
– apply the handbrake;
– turn the ignition key to the STOPpo-
sition;
– do not smoke;
– hand the special adapter over to the qua-
lified LPG refuelling personnel.
IMPORTANT Before refuelling, the LPG
refuelling personnel must ensure that the
adapter is correctly fitted to the filler.
WHEELS
The car does not have a spare wheel but
a tool box fig. 11that contains the “Au-
tomatic Fix&Go” quick tyre repair kit,
a tow ring and a screwdriver. The box is
located in the boot fig. 10, behind the rear
seat backrest.
To use the “Automatic Fix&Go” kit, see
the instructions in the Owner Handbook
that accompanies this supplement.

fig. 10F0Q0281m
IMPORTANT Different types of fuel pump
adapters exist in the various countries
where the car is sold. The adapter that co-
mes with the car in a special case is spe-
cifically designed for the country in whi-
ch the car is sold. If you are in a different
country, find out what type of adapter is
used there.
IMPORTANT Only use LPG for mo-
tor vehicles.
IMPORTANT Look after the LPG
adapter carefully so that it does not
get damaged.
