FIAT PANDA LPG
KNOWING YOUR CAR
Introduction
The LPG version of the car features two
fuel systems, one for petrol and one for
LPG.
Like the petrol system, the LPG system
is phased, sequential multipoint type with
special injectors.LPG
Multipoint injection system
This product is produced in strict collab-
oration with prestigious suppliers in the
LPG sector.
The injection system used on the car is an
efficient system in terms of engine per-
formance and is based on the injection of
LPG in a gaseous state.
In this system with four injectors, one for
each intake manifold, the fuel is injected
directly into the engine heat transfer
ducts thereby metering the LPG very pre-
cisely improving combustion and, at the
same time, excluding any possibility of
flame return.
By adapting the electronic control tech-
nology of petrol engines to meet the spec-
ifications of LPG, it has been possible to
achieve important results in terms of dri-
veability and controlling exhaust emissions.
Engines running on LPG have almost the
same torque/power specifications as when
running on petrol and, as a result, the per-
formance of the car is also comparable. What is LPG?
LPG (the abbreviation of liquefied petro-
leum gas) is a mixture of gas used as an
economical and safe primary energy
source.
Its main components are: propane gas and
butane gas mixed in various proportions.
These gases are a product of petroleum
refinement and are also present naturally
in oil fields and methane-producing de-
posits.
In its natural state this mixture is in a
gaseous state but, as the pressure in-
creases, at ambient temperature, it can
easily be turned into a liquid state.
LPG is a fuel with a low environmental im-
pact because it reduces the pollution pro-
duced by vehicle exhaust gases.

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".

LPG TANK
The vehicle has a (pressurized) tank A-fig. 3
for LPG in a liquid state that is toroidal
in shape and located in the housing for the
spare wheel with suitable protection.
The LPG in the tank Ais always in a liquid
and gaseous state, in physical equilibrium
conditions.
The liquid, which cannot be compressed,
dilates by around 0.25% for each increase
in temperature of one degree. For this
reason a suitable space allowing the in-
crease in volume of the liquid for all fore-
seeable temperature increases is guaran-
teed (e.g. car parked in the full sun in
summer) without compromising the in-
tegrity of the tank.
In effect, there is a safety valve that auto-
matically limits the refilling of the tank
(during refuelling) to a maximum level of
80% (liquid) of its total capacity.Periodically (at least once
every six months) it is advis-
able to let the LPG in the tank
run out and, at the first refu-
elling, check that the maximum ca-
pacity of 31litres is not exceeded
(27 litres for the VAN version) (surplus
of 2 litres is allowed) (see contents of
Capacities” paragraph in this supple-
ment). If the level is above 31litres
(27 litres for the VAN version) (surplus
of 2 litres is allowed) go to a Fiat deal-
er immediately.
LPG TANK CERTIFICATION
The LPG tank is certified in accor-
dance with current regulations.
In Italy the tank has a life of 10 years
from the registration date of the car.
If the vehicle has been registered in
a country other than Italy, the dura-
tion and the testing/inspection pro-
cedures of LPG tank can vary de-
pending on the national provisions in
force in that country. In any case,
when the time limit in the individ-
ual country has run out, go to a Fiat
Dealer to have the tank replaced.B-fig. 3containing the following infor-
mation:
– homologation country identification and
homologation number;
– type of gas for which it is designed (LPG);
– name of tank manufacturer;
– tank test pressure (30 bar);
– maximum refilling percentage (80%);
– tank dimensions;

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).

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.

FUEL CONSUMPTION
The fuel consumption figures given in the
table below are determined on the basis
of the homologation tests set down by
specific European Directives.
The procedures below are followed for
measuring consumption:
– urban cycle: begins with cold starting,
then follows a driving path simulating the
usage of the vehicle in town;
– extra-urban cycle: driving that simulates
using the vehicle out of town with fre-
quent acceleration in all gears; the speed
varies from 0 to 120 km/h;
– combined consumption: the weighting is
around 37% urban cycle and 63% extra-
urban cycle.IMPORTANT The type of route, traffic
situations, weather conditions, driving
style, general car condition, trim lev-
el/equipment/accessories, use of the cli-
mate control system, vehicle load, roof
rack and other situations that affect air
drag may lead to different fuel consump-
tion levels than those measured. (See
Saving fuel in the Starting and driving
chapter in the handbook).
LPG range
With reference to the combined con-
sumption figures, the range while running
on LPG is 433 km (378 km for the VAN
version).
According to the European Directive in force
Petrol LPG
(litres x 100 km) (litres x 100 km)
Urban 7.0 9.0
Extra-urban 4.6 5.9
Combined 5.5 7.0
If, when refuelling with LPG,
there is an irregularity and the
tank is filled to more than the
31litres (27 litres for the VAN
version) (allowing for a surplus of 2 litres)
get help immediately from a Fiat Deal-
er. Periodically (at least once every six
months) it is advisable to let the LPG
in the tank run out and, at the first re-
fuelling, check that it does not exceed
the maximum permitted capacity.
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".
