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.
fig. 1F0Z0802m
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".

SOLENOID VALVES
AND SAFETY DEVICES
The system has a solenoid valve located
on the pressure reduction unit and a so-
lenoid valve fitted inside the multiple valve
assembly on the tank.
The main function of these solenoid valves
is to interrupt/allow the flow of LPG to
the supply circuit.
The solenoid valves are open when:
– a request to run on LPG has been made;
– the optimum engine conditions are sat-
isfied (engine coolant temperature, mini-
mum revs level) for running on LPG;– there is enough LGP in the tank for op-
eration;
– the inertia switch has not been tripped.
The multivalve assembly fitted on the tank
includes:
– a valve that automatically stops the sup-
ply of LPG when the maximum permitted
filling level is reached (80% of the total
tank capacity);
– a flow limiter which, if a pipe is broken,
prevents the complete and sudden escape
of LPG;
– a one-way valve, located on the gas re-
turn pipe in the tank, which prevents LPG
reflux;
– a safety solenoid valve on the LPG sup-
ply, which either gives the go ahead or
prevents the escape of gas to the pressure
reduction unit; – a manual tap, upstream of the solenoid
valve, that separates the tank from the
LPG system to allow maintenance opera-
tions;
– a fuse pad which, in the event of
overheating (temperature above 120 °C),
totally eliminates the danger of excess
pressure making the LPG in the tank flow
out as quickly as possible in a controlled
manner;
– an analogue gauge showing the level of
LPG in the tank.

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:
A. LPG/petrol operating mode request
button;
B. LPG gauge: 5 leds of which 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 con-
dition;
ON. LPG operation mode indicator:
green LED on continuously, under the
buttonA;
OFF. petrol operation mode indicator:
yellow LED on continuously, under the
buttonA.
IMPORTANT When the ignition key is
turned to the MARposition the LEDs on
the ignition switch come on in accordance
with the following rule:
–with petrol operation mode se-
lected: yellow LED OFF activation;
–with LPG operation selected: all
LEDs on the switch are on continuously
and the green LED ONflashes.To select the type of fuel system desired
(LPG or petrol), press button A-fig. 7.
To change the type of fuel system, it is ad-
visable to operate the button with the ve-
hicle stationary and the engine running or,
whilst driving, after having released the ac-
celerator.
If the switching takes place during accel-
eration or pick-up, there may be a brief
flat spot (fall in power).

Do not switch between the
two operating modes whilst
starting the engine.

AT THE FILLING
STATION
LPG filler fitting
The gas filler is located next to the petrol
filler cap. It has a one-way valve, located
in the actual filler body.
To access the filler B-fig. 8, open the ac-
cess hatch Aand undo the cap C.
Observe the following precautions during
the refuelling operation:
– switch off the engine;
– apply the handbrake;
– turn the ignition key to the STOPpo-
sition;
– do not smoke;
– hand the special adaptor over to the
qualified LPG refuelling personnel.
IMPORTANT Before refuelling with LPG,
the qualified personnel should make sure
that the adaptor is correctly tightened on-
to the filler fitting.
IMPORTANT Depending on the country,
there are two types of adaptors for refu-
elling pumps. The adaptor that comes with
the car in a special case is specifically de-
signed for the country in which the car is
sold. If you are in a different country, find
out what type of adaptor is used there.
WHEELS
Wheel repair
The car does not have a spare wheel but
comes with a quick tyre repair kit known
as Fix&Go.
The kit is located on the left side of the
luggage compartment and is fastened by
Velcro.
For use, see the instructions in the main
Owner Handbook associated with this
supplement.
The tool box fig. 9is located under the
driver’s seat and fastened by Velcro.
FUSE REPLACEMENT
The LPG system components are protec-
ted by specific fuses. Contact a Fiat Dea-
lership if a fuse needs replacing.
For all other fuses, consult the Owner
Handbook that this supplement comes
with.
fig. 8F0Z0808m
fig. 9F0Z0607m
IMPORTANT Only use LPG for mo-
tor vehicles.
IMPORTANT Look after the LPG
adaptor carefully so that it does not
get damaged.
