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).
