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.

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.

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).

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.

(*) The figure already takes into account
the 80% tank filling limit and the residual
fluid required for the pump and 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 standardized.
During LPG operation, the “Instant con-
sumption” and “Average consumption”
readings are not significant, but remain
valid for all other functions.
IMPORTANT Only use LPG for mo-
tor vehicles. If, when refuelling with LPG,
the tank is filled with more
than the 38 litres, seek assis-
tance immediately from a Fi-
at 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 38
litres.
