FIAT PUNTO LPG
FUEL CUT-OFF SYSTEM
In the case of an impact to the vehicle, the
petrol supply is immediately cut off caus-
ing 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 “Dashboard
and 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, yellow LED on con-
stantly) and switches automatically soon
after.
There must always be some petrol in the
tank to protect the petrol pump.
To carry out the starting manoeuvre cor-
rectly, see the warnings and advice in the
Owner Handbook under the chapter
“Starting the engine” enclosed with this
Supplement.
In this condition it is possible
to continue driving running on
petrol (excluding the LPG fu-
el system). To stop the
buzzer, press button A: the green ON
LED will go out and the yellow OFF
LED will remain on constantly. Go to a
Fiat Dealer as soon as possible to have
the system checked.
System failure signalling
The car has an autodiagnostic system ca-
pable of signalling any malfunctions in the
LPG fuel system through the green ON
LED fig. 7flashing. 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
running on petrol.
This condition will be shown by:
– the yellow OFFLED on constantly;
– the green ONLED flashing;
– an acoustic warning from the switch
buzzer (slow frequency).
