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”.

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.

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.

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.

NOTE In particularly harsh climate con-

40% demineralised water is recommen-
ded.
The LPG supply system is

the switch; this function activates only
after a consistent variation in fuel level
has been detected. You are therefore
