FIAT BRAVO LPG
ELECTRONIC CONTROL
UNIT
The car has a dedicated electronic control
unit for the LPG system fig. 7; it uses the
incoming signals from the petrol injection
control unit and converts them into signals
for the injection of the LPG.
The control unit for the injectors has the
same strategy as the petrol control unit
(timed, sequential, multipoint).
LPG/PETROL SWITCH
The LPG/petrol switch fig. 8is located on
the central console near the handbrake
and includes:
A. LPG/petrol operating mode request
button;
B. LPG gauge: 5 LEDs (4 green and 1 red
to indicate the reserve). The red LED only
comes on when the last green LED goes
out.
The red LED indicates the reserve status;
ON. LPG operating mode indicator: green
LED on continuously, located under but-
tonA;
OFF. petrol operating mode indicator:
amber LED on continuously, located abo-
ve buttonA.
IMPORTANT When the ignition key is
turned to the MAR – ONposition, the
LEDs on the switch come on as follows:
– with petrol operation mode selec-
ted: amber OFFLED on;
– with LPG operation mode selected:
all LEDs on the switch are on continuou-
sly and the green ONLED flashes.
To select the type of fuel system desired
(LPG or petrol), press button A-fig. 8.
To change the type of fuel system, it is ad-
visable to operate the button with the car
stationary and the engine running or, whil-st driving, after having released the acce-
lerator.
If switching takes place during acceleration
or pick-up, there may be a brief flat spot
(drop in power).
Do not switch between the two operating
modes when starting the engine.

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).

CAPACITIES
Petrol
Petrol . . . . . . . . . . . . . . . . . litres 57
– including a reserve of . . . litres 8÷10
LPG
– maximum refuelling
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.
Engine cooling system

50% PARAFLU
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
