FIAT BRAVO LPG
LPG TANK
The car has a (pressurised) tank A-fig. 3
for collecting LPG in a liquid state. It is
ring-shaped and located in the spare wheel
compartment with suitable protection.
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 increa-
se in temperature of one degree. For this
reason there is a suitable space allowing
for the increase in volume of the liquid for
all foreseeable temperature increases (e.g.
car parked in the full sunlight in the sum-
mer) without compromising the integrity
of the tank.
There is a safety valve that automatically
limits the refilling of the tank (during re-
fuelling) to a maximum level of 80 % (li-
quid) of its total capacity.Periodically (at least once
every six months), it is advi-
sable to let the LPG in the
tank run out and, at the next
refuelling, check that it does not ex-
ceed the maximum capacity of 41 li-
tres (with a tolerance of 2 litres excess)
(see instructions in the “Capacities”
paragraph of this supplement). If the
value is above 41 litres (with a toleran-
ce of 2 litres excess), contact a Fiat Dea-
lership 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 country other than Italy, the dura-
tion and the testing/inspection pro-
cedures of the LPG tank can vary de-
pending on the legal requirements in
that country. In any case, after the ti-
me prescribed by the legal require-
ments in the individual countries, ha-
ve it replaced by a Fiat Dealership.There is a plate on the tank B-fig. 3con-
taining the following information:
– homologation country identification and
homologation number;
– type of gas for which it is designed (LPG);
– name of cylinder manufacturer;
– cylinder test pressure (30 bar);
– maximum refilling percentage (80%);
– tank dimensions;
– nominal tank capacity in litres;
– cylinder manufacture date (month/year);
– cylinder serial number.

FIAT BRAVO LPG
SWITCHING FROM PETROL
TO LPG
With petrol fuel supply: press the button
A-fig 8, the switch to LPG will take pla-
ce automatically at the first significant ac-
celeration.
During switching:
– the LPG gauge Bcomes on;
– the amber OFFLED goes out (petrol
operating mode);
– the green ONLED comes on, switching
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 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 When starting up at outsi-
de temperatures of below −10
°C, the
switching times from petrol to LPG in-
crease to allow the pressure regulator to
heat up.Running out of LPG
If the LPG runs out, switching to petrol
takes place automatically with:
– the amber OFFLED on constantly;
– the green ONLED flashing;
– an acoustic signal from the switch (high
frequency).
IMPORTANT The acoustic signal warns
the driver that the engine is running on pe-
trol; therefore, they must refuel with LPG
before it runs out.
THE acoustic signal can be deactivated by
pressing the switching button A.
Do not switch between the
two operating modes whilst
starting the engine.
Switching from LPG to petrol
With LPG supply: press the buttonA-fig.8.
During switching:
– the LPG gauge Bgoes out;
– the amber OFF LED comes on and
stays on (petrol operating mode);
– the green ONLED goes out (LPG ope-
rating mode).

FUEL CUT-OFF SYSTEM
In the event of an impact to the car, the
petrol and injection supply is cut off im-
mediately, causing 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 “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, amber LED on con-
stantly), and switches from petrol to LPG
automatically soon after.
There must therefore always be some pe-
trol in the tank to protect the petrol
pump.
To carry out the starting manoeuvre cor-
rectly, see the warnings and advice in the
“Starting the engine” chapter of the Ow-
ner Handbook.
In this situation, you can con-
tinue driving, with the car run-
ning on petrol (excluding the
LPG fuel system). To turn off
the acoustic signal, press button A: the
green ON LED will go out and the am-
ber OFF LED will remain on constan-
tly. Go to a Fiat Dealership as soon as
possible to have the system checked.
SYSTEM FAILURE SIGNALLING
The car has a self-diagnosis system capa-
ble of signalling any malfunctions in the
LPG fuel system through the green ON
LED fig. 8flashing. 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
petrol.
This condition will be shown by:
– the amber OFFLED on constantly;
– the green ONLED flashing;
– an acoustic signal from the switch (low
frequency).

REFUELLING THE CAR
LPG FILLER CAP
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. 9, 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 adapter over to the qua-
lified LPG refuelling personnel.
IMPORTANT Before refuelling, the LPG
refuelling personnel must ensure that the
adapter is correctly fitted to the filler.
WHEELS
The car does not have a spare wheel but
a tool box fig. 11that contains the “Au-
tomatic Fix&Go” quick tyre repair kit,
a tow ring and a screwdriver. The box is
located in the boot fig. 10, behind the rear
seat backrest.
To use the “Automatic Fix&Go” kit, see
the instructions in the Owner Handbook
that accompanies this supplement.

fig. 10F0Q0281m
IMPORTANT Different types of fuel pump
adapters exist in the various countries
where the car is sold. The adapter that co-
mes with the car in a special case is spe-
cifically designed for the country in whi-
ch the car is sold. If you are in a different
country, find out what type of adapter is
used there.
IMPORTANT Only use LPG for mo-
tor vehicles.
IMPORTANT Look after the LPG
adapter carefully so that it does not
get damaged.

LPG

capacity (*) . . . . . . . . . . . . . litres 41
(*) The figure already takes into account
the 80% tank filling limit and the residual
fluid required for the pump and the maxi-
mum permitted capacity. In addition,
said figure may vary slightly in diffe-
rent capacities owing to: differences
between network pump supply pres-
sures, pumps with different sup-
ply/stop specifications, tank not com-
pletely in reserve conditions.It should be remembered that when using
a fuel like LPG, the range is very variable
because, in addition to the driving and
maintenance conditions of the car, it also
depends on the different composition of
the gas which may vary, not only seaso-
nally, but also from supplier to supplier.
LPG is, in effect, a composition of gas (bu-
tane and propane) mixed in a way that
may not be standardized.
The Trip Computer’s range is indicative
and refers to petrol operation only.
During LPG operation, the “Instant con-
sumption” and “Average consumption”
readings are not significant, but 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 41litres (with a toleran-
ce of 2 litres in excess), seek as-
sistance immediately from a Fiat Dea-
lership. Periodically (at least once every
six months), it is advisable to let the
LPG in the tank run out and, at the fir-
st refuelling, check that it does not ex-
ceed the maximum capacity.

UP........................ litres 6.3
NOTE In particularly harsh climate con-
ditions, a mixture of 60% PARAFLU
UPand
40% demineralised water is recommen-
ded.
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 variation in fuel level
has been detected. You are therefore
advised to fill up with fuel at the first
LPG refuelling to obtain a more preci-
se indication of the level
