FIAT PUNTO LPG
The system extreme operat-
ing temperatures are between
-20°C and 100°C.
Selecting the type of fuel supply
The car is configured for running inde-
pendently 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 acceler-
ation.
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 the op-
eration of the fuel pump. When running on LPG, when
the last red LED on gas quan-
tity indicator (visible on the
switch) comes on, refuelling is
advisable. If the LPG runs out during
LPG operation, the system automati-
cally 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 in the switch.
In addition, it is advisable to periodically
use up the petrol in the tank (until the re-
serve warning light comes on) in order to
ensure that the petrol does not become
old and possibly deteriorate.
The petrol/LPG switch A-fig. 1, located
on the protective fuse flap (left side of the
dashboard) allows the driver to select
petrol or LPG operation at their discre-
tion.

When painting in an oven, the
LPG tank should be removed
from the car and later care-
fully refitted by a Fiat Dealer.
Although the LPG system has numer-
ous safety features, it is advisable to
close the manual tap on the tank every
time the car is not in use for a long pe-
riod, transported on other vehicles or
moved in an emergency as a result of a
breakdown or accident.
Active safety
The car has the same active safety speci-
fications as other versions.
The Fiat Punto LPG is equipped
with 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 malfunctions and
lead to a reduction in safety therefore,
in the case of problems, go to a Fiat
Dealer. When towing or raising the
car, to prevent damage to the gas sys-
tem parts, follow the instructions in the
Owner 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. In particular,
the tank mountings (located in the spare
wheel housing) have been designed to ex-
ceed the Fiat safety standards for impact
tests.
When running on LPG, the flow of gas (in
a liquid state) leaving the tank, passes
through the dedicated pipe to the pres-
sure regulator where there is a safety so-
lenoid valve that stops the flow of LPG
when the key is turned off or when a
change of fuel is selected by the driver (de-
cision 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.
The two solenoid valves are closed in the
case of an impact after which the engine
cuts out caused by the fuel cut off system.
The LPG tank meets the legal safety stan-
dards of the countries in which the ver-
sion illustrated this Supplement is mar-
keted.

Switching from petrol to LPG
When running on petrol: press the 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 is a series of 5 LEDs B(1 red and
4 green) on the left side 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 In the case of starting at
outside temperatures of below -10°C, the
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.
It is possible to deactivate the buzzer by
pressing 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 the button
A-fig. 7.
During switching:
– the LPG gauge Bgoes out;
– the yellow OFFLED 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 from the switch
buzzer (fast frequency).

FUEL CUT-OFF SYSTEM
In the case of an impact to the vehicle, the
petrol supply is immediately cut off caus-
ing 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 “Dashboard
and 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, 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 condition it is possible
to continue driving running on
petrol (excluding the LPG fu-
el 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 an autodiagnostic system ca-
pable of signalling any malfunctions in the
LPG fuel system through the green ON
LED fig. 7flashing. 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
running on petrol.
This condition will be shown by:
– the yellow OFFLED on constantly;
– the green ONLED flashing;
– an acoustic warning from the switch
buzzer (slow frequency).
