FIAT PUNTO LPG
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.

FIAT PUNTO LPG
LPG TANK
The vehicle has a (pressurized) tank A-
fig. 3for LPG in a liquid state that is
toroidal in shape and located in the hous-
ing for the spare wheel with suitable pro-
tection.
The LPG in the tank Ais always in a liquid
and gaseous state, in physical equilibrium
conditions.
The liquid, which cannot be compressed,
dilates by around 0.25% for each increase
in temperature of one degree. For this
reason a suitable space allowing the in-
crease in volume of the liquid for all
forseeable temperature increases is guar-
anteed (e.g. car parked in the full sun in
summer) without compromising the in-
tegrity of the tank.
In effect, there is a safety valve that auto-
matically limits the refilling of the tank
(during refuelling) to a maximum level of
80% (liquid) of its total capacity.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 max-
imum capacity of 38 litres (see instruc-
tions in “Capacities” paragraph in this
Supplement). If the value is above 38
litres, go to a Fiat Dealer immediately.
LPG TANK CERTIFICATION
The LPG tank is certified in accor-
dance with the regulations in force.
In Italy the tank has a life of 10 years
from the registration date of the car.
If the car has been registered in a dif-
ferent country from Italy, the life of
the LPG tank and test/inspection
procedures may vary depending on
the laws in force in that particular
country. In any case, when the time
limit in the individual country has run
out, go to a Fiat Dealer to have the
tank replaced.There is a plate on the tank B-fig. 3con-
taining the following information:
– homologation country identification and
homologation number;
– type of gas designed for (LPG);
– name of tank manufacturer;
– tank test pressure (30 bar);
– maximum refilling percentage (80%);
– tank dimensions;
– nominal tank capacity in litres;
– tank manufacture date (month/year);
– tank serial number.

AT THE FILLING
STATION
LPG filler
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. 8, 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 adaptor over to the
qualified LPG refuelling personnel.
IMPORTANT Before refuelling with LPG,
the qualified personnel should make sure
that the adapator is correctly tightened
onto the filler fitting.
IMPORTANT Depending on the country,
there are two types of adaptors for refu-
elling pumps. The adaptor that comes with
the car in a special case is specifically de-
signed for the country in which the car is
sold. If you are in a different country, find
out what type of adapator is used there.
WHEELS
Wheel repair
The car does not have a spare wheel but
comes with a quick tyre repair kit known
as Fix&Go.
The kit is located on the left side of the
luggage compartment and is fastened by
velcro.
See the instructions in the booklet that
this supplement comes with.
The tool box fig. 9is located under the
driver’s seat and fastened by velcro.
FUSE REPLACEMENT
The LPG system components are pro-
tected by a 20A fuse F81 (power supply +
battery) installed, depending on the ver-
sion, near the battery or in the engine
compartment junction unit and a 5A fuse
F16 (power supply + ignition) in the en-
gine compartment junction unit.
For all the other fuses, consult the Own-
er Handbook that this supplement comes
with.

IMPORTANT Only use LPG for mo-
tor vehicles.
IMPORTANT Look after the LPG
adapator carefully so that it does not
get damamged.
