FIAT BRAVO LPG
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 accele-
ration.
This is the time required to reach opti-
mum conditions (engine coolant tempe-
rature, minimum revs level) for the swit-
ch to LPG. Therefore, there must
always be some petrol in the tank (at
least 1/4 full)in order not to compro-
mise the operation of the fuel pump. When running on LPG, when
the last red LED on the gas
gauge (visible on the switch)
comes on, refuelling is advisa-
ble. If the LPG runs out when in LPG mo-
de, the system automatically switches to
petrol mode. This is indicated by: the
amber LED staying on and the green
LED flashing, the fuel level LEDs going
out and an audio signal from 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 fig. 1, located on
the central tunnel (next to the gear lever)
allows the driver to select petrol or LPG
operation as they see fit.

Remember that, once LPG re-
fuelling is complete, it is ne-
cessary to switch again by
pressing the button fig. 1 to
run the car on gas.
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”.

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.

(*) 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.
