IMPORTANT If the ignition key is turned
to MAR, all the device LEDs will stay
on for approximately 4 seconds (check
function).
Engine starting always occurs on petrol;
then, depending on the position of the
switch A fig. 44 the following occurs:
the switch A pressed on the right
side (identified by the symbol)
indicates petrol operation with
activation of the associated amber LED
C;
switch A pressed on the left side
(identified by the symbol G) indicates
LPG operation with activation of the
associated green LED D.
Five LEDs B (one amber and four
green) on the top part of the switch
display the amount of LPG in the
cylinders.
If the LPG runs out, the system
automatically switches to petrol: the
orange LED C next to the switch
comes on and the green LED D
indicating LPG operation goes off.
When the car is refuelled with LPG after
a standard start-up on petrol, the fuel
system automatically returns to LPG:
the orange LED C next to the switch
goes off and the green LED D for LPG
F0S0673
operation turns on.
If you specifically wish to run on petrol,
press the switch A on the right-hand
side.
The amber LED C next to the switch
will turn on to indicate that switching
has taken place (the LPG fuel system
has been entirely disabled).
The fuel supply can only be returned to
LPG by operating switch A again,
green LED D next to the switch will turn
on to indicate that switching has taken
place.
In addition, when starting at outside
temperatures below approximately
–10°C, the switching times from petrol
to LPG increase to allow the pressure
regulator/reduction unit to heat up.
IMPORTANT If switching takes place
during acceleration or pick-up, there
may be a brief drop in power.

WARNING
35) Note that in some countries (including
Italy) there are legal restrictions in force
for parking/garaging motor vehicles fuelled
by gas that is denser than air; LPG comes
under this category.
36) If gas is smelt, switch from LPG
operation to petrol operation and
immediately go to a Fiat Dealership to have
the vehicle checked and possible system
faults excluded.
37) Do not switch between the two
operating modes whilst starting the engine.
38) The LPG supply system is equipped
with a "consumption" 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. It is therefore advisable to fill
up with fuel at the first LPG refuelling
to obtain a more "precise" indication of the
level.
