FIAT IDEA LPG
The system extreme operat-
ing temperatures are between
-20°C and 100°C.
Selecting the type of fuel supply
The car is configured to run independently
on either petrol or LPG.
The engine is always started on petrol
with an automatic shift to LPG after about
40 seconds, at the first significant accel-
eration.
This is the time required to reach opti-
mum conditions (engine coolant temper-
ature, minimum revs level) for the switch
to LPG. As far as what has been said
is concerned, there must always be
some petrol in the tank (at least 1/4
full)in order not to compromise fuel
pump operation.
In addition, from time to time it is advis-
able to use up all the petrol in the tank
(until the reserve warning light comes on),
in order to ensure that the petrol does
not become old and possibly deteriorate. When running on LPG, when
the last red LED gas quantity
indicator (visible on the
switch) comes on, you should
refuel. If the LPG runs out during LPG
operation, the system automatically
switches to running on petrol shown by:
the amber LED coming on constantly
and the green LED flashing, the fuel
level LEDs going out and a buzzer
sounded by the switch.
The petrol/LPG switch A - Fig. 1, locat-
ed on the protective fuse compartment
(on the left of the dashboard) allows the
driver to select petrol or LPG operation
at your own discretion.
fig. 1F0H0774m
Please remember that after
filling the LPG tank, you will
need to switch fuel by press-
ing the button A-fig 1 to run
the engine on LPG.
The LPG supply system is
equipped with a "consump-
tion" function linked to the LED display
of LPG level on the switch; this function
activates only after a consistent varia-
tion in fuel level has been detected. You
are therefore advised to fill up with fu-
el at the first LPG refuelling to obtain a
more precise indication of the “level".

When oven painting, the LPG
tank should be removed from
the car and later carefully re-
fitted by a Fiat Dealer. Al-
though the LPG system has numerous
safety features, it is advisable to close
the manual tap on the tank whenever
the car is not used for a long period, is
transported on other vehicles or moved
in an emergency as a result of a break-
down or accident.
Active safety
The car has the same active safety speci-
fications as other versions.
The Fiat Idea LPG is equipped
with a gaseous LPG injection
system designed specifically
for the car: it is therefore
strictly prohibited to alter the config-
uration of the system and components.
The use of other components or ma-
terials could cause malfunctioning and
lead to a reduction in safety. Please re-
fer to a registered Fiat dealer for any
assistance necessary. When towing or
raising the car, to prevent damage to
the gas system parts, follow the in-
structions in the Owner’s Handbook in
the ‘Towing the car’ chapter.
It should be pointed out that
in some countries (including
Italy) there are legal restrictions in
force for parking/garaging motor ve-
hicles with gas that has a higher den-
sity than air. LPG comes under this
category.
WARNINGPASSIVE SAFETY -
ACTIVE SAFETY
Passive safety
The car has the same passive safety spec-
ifications as other versions. Specifically,
tank mountings (located in the spare
wheel housing) have been designed to pass
impact tests in accordance with Fiat safe-
ty standards.
When running on LPG, the flow of gas (in
a liquid state) leaving the tank, passes
through the specific pipe to the pressure
regulator, where there is a safety solenoid
valve that stops the flow of LPG when the
key is turned off or when the driver se-
lects a fuel change (decision to run on
petrol).
Together with the regulator solenoid
valve, a second solenoid valve, in the tank,
closes the LPG pipe at the tank outlet.
In the event of impact, the two solenoid
valves are closed, after which the engine
cuts out due to the fuel cut off system.
The LPG tank meets the legal safety stan-
dards of the countries in which the ver-
sion illustrated in this Supplement is mar-
keted.

Switch from petrol to LPG
When running on petrol: press button A
- Fig 7, the switch to LPG will take place
automatically at the first significant accel-
eration.
During switching:
– the LPG gauge Bcomes on;
– the yellow OFFLED goes out (petrol
operating mode);
– the green ONLED comes on, switch-
ing 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 falls
below about 1/5 of the capacity of the
tank, only the red (reserve) LED remains
on, signalling the need to refuel.
IMPORTANT Where starting the engine
in external temperatures of below -10°C,
switching times from petrol to LPG in-
crease to allow the pressure regulator to
become warm enough.IMPORTANT The buzzer warns the dri-
ver that the engine is running on petrol;
therefore they must refuel with LPG be-
fore it runs out.
THE buzzer can be deactivated by press-
ing switching button A.
Do not switch between the
two operating modes whilst
starting the engine.Switching from LPG to petrol
When running on LPG: press buttonA -
fig. 7.
During switching:
– the LPG gauge Bgoes out;
– the yellow OFF LED comes on con-
stantly (petrol operating mode);
– the green ONLED goes out (LPG op-
erating mode).
LPG used up
If the LPG runs out, switching to petrol
takes place automatically with:
– the yellow OFFLED on constantly;
– the green ONLED flashing;
– an acoustic warning sounded by the
switch buzzer (fast frequency).

FUEL CUT-OFF SYSTEM
In the event of an impact to the vehicle,
the petrol supply is cut off immediately,
causing the engine to cut out and, as a re-
sult, the LPG safety solenoid valves to
close.
For further information, please see the
‘Fuel cut off system’ paragraph in the
‘Dashboard and Controls’ chapter in the
Owner’s Handbook.
STARTING THE
ENGINE
The engine is always started on petrol,
even with the switch in the LPG position
(green LED flashing, yellow LED on con-
stantly) and switches automatically soon
after.
There must always be some petrol in the
tank to protect the petrol pump.
To carry out the starting manoeuvre cor-
rectly, see the warnings and advice in the
Owner Handbook under the chapter
“Starting the engine” enclosed with this
Supplement.
In this situation, you can con-
tinue driving, with the car run-
ning on petrol (excluding the
LPG fuel system). To stop the
buzzer, press button A: the green ON
LED will go out and the yellow OFF
LED will remain on constantly. Go to a
Fiat Dealer as soon as possible to have
the system checked.
System failure signalling
The car has a self-diagnostic system ca-
pable of signalling any malfunctions in the
LPG fuel system through the green ON
LED Fig. 7flashing. In the event of faults
that could affect correct engine operation,
the LPG control unit will automatically
switch from LPG operation to running on
petrol.
This situation will be shown by:
– the yellow OFFLED on constantly;
– the green ONLED flashing;
– an acoustic warning sounded by the
switch buzzer (slow frequency).

(*) The figure already takes into account
the 80% tank filling limit and the residual
fluid required for the pump, it is the max-
imum permitted capacity. There may be
slight variations to this figure as a re-
sult of: differences between the supply
pressures of pumps in the network,
pumps with different supply/cut off
specifications, tank not completely in
reserve condition.Note than when using a fuel such as LPG,
the range is very variable because, in ad-
dition to the vehicle driving and mainte-
nance conditions, it also depends on the
composition of the gas which may vary,
not only seasonally, but also from suppli-
er to supplier. LPG is, in effect, a compo-
sition of gas (butane and propane) mixed
in a way that may not be standardised.
The trip meter indication on range is in-
dicative and refers to petrol operation on-
ly.
During LPG operation, the ‘Instant con-
sumption’ and ‘Average consumption’
readings are not significant, whereas all
other functions remain valid.
IMPORTANT Only use LPG for mo-
tor vehicles. If, when refuelling with LPG,
the tank is filled with more
than the 31 litres, seek imme-
diate assistance from a Fiat
Dealer. Periodically (at least once
every six months) it is advisable to let
the LPG in the tank run out and, at the
first refuelling, check that it does not
exceed the maximum capacity of 31
litres.
The LPG supply system is
equipped with a "consump-
tion" function linked to the LED display
of LPG level on the switch; this function
activates only after a consistent varia-
tion in fuel level has been detected. You
are therefore advised to fill up with fu-
el at the first LPG refuelling to obtain a
more precise indication of the “level".
