2020 FIAT 500 petrol tank

33)For safety reasons, the bonnet must
always be properly closed while the car is
travelling. Make sure that the bonnet is
properly closed and that the lock is
engaged. If you notice when driving that
the bonnet has not been properly locked,
stop immediately and close the bonnet
correctly.
34)Use both hands to lift the bonnet.
Before lifting, check that the windscreen
wiper arms are not raised from the
windscreen, that the vehicle is stationary
and that the handbrake is engaged.VERSION WITH LPG
SYSTEM
25)
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 timed, sequential
multipoint type with special injectors.
PASSIVE SAFETY / ACTIVE SAFETY
35) 36)
26) 27)
Passive safety
The car has the same passive safety
specifications as other versions. In
particular, the tank mountings (located
in the spare wheel housing) have been
designed to exceed the Fiat safety
standards for impact tests.
Active safety
The car has the same active safety
specifications as other versions.Although the LPG system has
numerous safety features, it is advisable
to proceed as follows every time the
car is not in use for a long period or
moved in an emergency as a result of a
fault or accident:
unscrew the fixing devices A fig. 41,
then remove the cover B;
close the LPG cock by rotating the
knurled ring nut C fig. 42 clockwise;

refit the cover and retighten the
fastening devices.
LPG TANK
28)
The car has a (pressurised) tank A fig.
43 for accumulating LPG in a liquid
state. It is ring-shaped and located in
the spare wheel compartment with
suitable protection.
The LPG in the tank is always in both a
liquid and gaseous state, in physical
balance between the two stages.The liquid, which cannot be
compressed, dilates by around 0.25%
for each increase in temperature of
one degree. For this reason a suitable
free gap allowing the increase in volume
of the liquid for all expected
temperature increases is guaranteed
(e.g. car parked in the sunshine in
summer), without compromising tank
integrity.
A safety valve has been fitted to this
end, to automatically limit the refilling of
the tank (during refuelling) to a
maximum level of 80% (liquid) of its
total capacity.
LPG tank certification
The LPG tank is certified in accordance
with the regulations in force.
In Italy, the tank has a life of 10 years
starting from the car registration date. If
the vehicle has been registered in a
country other than Italy, the duration
and the testing/inspection procedures
of the LPG tank can vary depending on
the national laws of that country. In all
case, when the time limit for your
country has expired, go to a Fiat Dealer
to have the tank replaced.
The tank identification data are printed
on the tank, under the multivalve unit:
type-approval country identification
and type-approval number;
type of gas for which it is designed
(LPG);
name of tank manufacturer;
tank commissioning pressure (30
bar);
maximum refilling percentage (80%);
tank dimensions;
rated tank capacity in litres;
tank manufacture date (month/year);
tank serial number.
LPG/PETROL SWITCH
37)
29)
It is located in the centre tunnel fig. 44
and includes:
Apetrol/LPG switch.
BLPG quantity indicator; 5 LEDs,
four green and one orange to indicate
reserve. The orange LED turns on when
only one green LED is on.
Cpetrol operating mode indicator:
orange LED next to the switchA.
This function is controlled directly by
the LPG control unit.
DLPG operating mode indicator:
green LED next to the switchA. This
function is controlled directly by the
LPG control unit.

KNOWING YOUR CAR

WARNING
25)The system operates at temperatures
ranging between −20°C and 100°C.
26)The car is equipped with a gaseous
LPG injection system designed specifically
for it: it is therefore absolutely forbidden
to alter the configuration of the system or
its components. The use of other
components or materials could cause
malfunctions and lead to a reduction in
safety; therefore, in the case of problems,
contact a Fiat Dealership. To prevent
damage to the gas system parts when
towing or raising the vehicle, follow the
instructions in the "Towing the vehicle"
paragraph of the Owner Handbook.
27)When painting in an oven, the LPG
tank must be removed from the car and
later refitted by a Fiat Dealership. Although
the LPG system has numerous safety
features, it is advisable to proceed
as follows every time the vehicle is not in
use for a long period or moved in an
emergency as a result of a breakdown or
accident: unscrew the fastening devices A
fig. 41, then remove the cover B. Close
the LPG cock rotating the ring nut C
clockwise fig. 42; refit the cover and tighten
the fixing devices.28)Periodically (at least once every six
months), it is advisable to let the LPG in the
tank run out and, at the next refuelling,
check that it does not exceed the
maximum capacity of 30.5 litres (reserve
included) (with a tolerance of 2 litres
excess) (see instructions in the "Capacities"
paragraph). If the level is above 30.5 litres
(reserve included) contact a Fiat Dealership
immediately.
29)In particular usage conditions, such as
starting and operation at low ambient
temperature or LPG supply with low
propane content, the system may switch
temporarily to petrol operation, without
a visual indication of switching on the
selector. If the level of LPG in the tank is
low or there is a request for high
performance (e.g. overtaking, car fully
laden, steep hills): the system can
automatically switch to petrol operation to
guarantee the required engine
performance; in this event, the performed
switching is shown by the orange (petrol)
LED lit and the green (LPG) LED off on the
switch. When the above conditions stop,
the system automatically restores the LPG
operation; the orange (petrol) LED turns
off and the green (LPG) LED is lit on the
switch. To achieve the automatic switching
described above, make sure that there is
always enough fuel in the petrol tank.
30)It is strictly forbidden to use any
additive in the LPG.

KNOWING YOUR CAR

STARTING THE
ENGINE
121) 122)
36) 37) 39) 40)
Before starting the engine, adjust the
seat, the interior rear view mirrors,
the door mirrors and fasten the seat
belt correctly.
Never press the accelerator pedal for
starting the engine.
The Start&Stop, ECO and AUTO
functions are activated automatically
whenever the engine is started.
PETROL VERSIONS
Starting the engine
Proceed as follows:
engage the handbrake and put the
gear lever in neutral;
fully depress the clutch pedal
without touching the accelerator;
turn the ignition key to AVV and
release it as soon as the engine starts.
If the engine does not start at the
first attempt, return the ignition key to
STOP before repeating the starting
procedure.If, when the ignition key is at MAR, the
instrument panel warning light or the
symbol
remains lit together with
warning light
turn the key to STOP
and then back to MAR. If the warning
light remains on, try with the other keys
provided with the car.
Contact a Fiat Dealership if you still
cannot start the engine.
VERSIONS WITH
DUALOGIC
TRANSMISSION
123)
The system allows the engine to be
started both with a gear engaged and
with the transmission in neutral (N).
However, the brake pedal must always
be pressed first if neutral is not
engaged. It is therefore advisable to
position the gear lever at N before
starting the engine.
LPG VERSIONS
The engine always starts up on petrol
independently of the previously
selected mode.
38)
WARNING
121)It is dangerous to run the engine in
enclosed areas. The engine consumes
oxygen and engine exhaust contains
carbon dioxide, carbon monoxide and
other toxic gasses.
122)Remember that the brake servo and
electrical power steering system are not
operational until the engine is started,
therefore a greater effort will be required to
press the brake pedal or turn the steering
wheel.
123)If the engine fails to start with a gear
engaged, the potentially dangerous
situation due to the fact that the gearbox is
automatically placed in neutral will be
signalled by an acoustic signal.
WARNING
36)It is advisable not to demand maximum
performance from your car (e.g. excessive
acceleration, long distances at maximum
rpm, excessively intense braking, etc.)
when it is first used.
37)When the engine is switched off never
leave the key turned to MAR to prevent
useless current absorption from draining
the battery.
38)There must therefore always be
enough petrol in the tank to protect the
petrol pump and to guarantee temporary
switching from LPG to petrol operation.

Top speed
Fuel consumption considerably
increases as speed increases. Maintain
a constant speed, avoiding
unnecessary braking and acceleration,
which cost in terms of both fuel
consumption and emissions.
Acceleration
Accelerating violently severely affects
consumption and emissions:
acceleration should be gradual and
should not exceed the maximum
torque.
CONDITIONS OF USE
Cold starting
Short journeys and frequent cold starts
do not allow the engine to reach
optimum operating temperature.
Consequently, both consumption (from
+15 to +30% on the urban cycle) and
emissions will increase.
Traffic and road conditions
High fuel consumption is caused by
heavy traffic, for instance when
travelling in a queue with frequent use
of low gears or in cities with many traffic
lights. Winding mountain roads and
rough road surfaces also adversely
affect consumption.Stops in traffic
During prolonged hold-ups (e.g. level
crossings) switch off the engine.REFUELLING THE
VEHICLE
138) 139) 140)
Before refuelling, make sure that the
fuel type is correct. Also stop the
engine before refuelling.
PETROL VERSIONS
Only use unleaded petrol with a number
of octanes (R.O.N.) not lower than 95
(EN228 specification).
IMPORTANT An inefficient catalytic
converter leads to harmful exhaust
emissions, thus contributing to air
pollution.
IMPORTANT Never introduce leaded
petrol to the tank, even in small
amounts in an emergency, as this
would damage the catalytic converter
beyond repair.
REFUELLING CAPACITY
To ensure that you fill the tank
completely, top up twice after the first
click of the fuel supply gun. Further
top-ups could cause faults in the fuel
feeding system.

the qualified personnel must make
sure that the adapter is correctly
screwed onto the filler.
IMPORTANT Depending on the country,
there are various types of adapters for
the refuelling pump. The adapter C
fig. 86 that comes with the car in a
special case is specifically designed for
the country in which the car is sold. If
you are in a different country, find out
what type of adapter is used there.
IMPORTANT Look after the LPG
adapter carefully so that it does not get
damaged.
IMPORTANT Only use LPG for motor
vehicles.
