FIAT PANDA LPG
The system extreme operat-
ing temperatures are between
-20°C and 100°C.
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 acceleration.
This is the time required to reach opti-
mum conditions (engine coolant temper-
ature, minimum revs level) for the switch
to LPG. As far as what has been said
is concerned, there must always be
some petrol in the tank (at least 1/4
full)in order not to compromise the op-
eration of the fuel pump.
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. When running on LPG, when
the last red LED on gas quan-
tity indicator (visible on the
switch) comes on, refuelling is
advisable. If LPG runs out when in LPG
mode, the system automatically switch-
es to petrol mode. This is indicated by:
the amber LED coming on constantly
and the green LED flashing, the fuel
level LEDs going out and a buzzer
sounded by the switch.
The petrol/LPG switch A-fig. 1, located
on the protective fuse flap (left side of the
dashboard) allows the driver to select
petrol or LPG operation at his discretion.

Please remember that after
filling the LPG tank, you will
need to switch fuel by press-
ing the button A-fig 1 to run
the engine on LPG.
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 varia-
tion in fuel level has been detected. You
are therefore advised to fill up with fu-
el at the first LPG refuelling to obtain a
more precise indication of the “level".

ELECTRONIC
CONTROL UNIT
The vehicle has a dedicated electronic
control unit for the LPG system; it uses
the incoming signals from the petrol in-
jection control unit and converts them in-
to signals for the injection of the LPG.
The control unit for the injectors has the
same strategy as the petrol control unit
(phased, sequential, multipoint).
LPG/PETROL SWITCH
The LPG/petrol switch fig. 7is located on
the protective fuse flap (left side of the
dashboard) and includes:
