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.

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).

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.

tor vehicles.
IMPORTANT Look after the LPG
adapator carefully so that it does not
get damamged.

CAPACITIES

(*) 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.
