2018 FIAT 500L fuel cap

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.
SELECTION OF
PETROL/LPG SUPPLY
TYPE
The fig. 55 button (petrol/LPG switch)
allows you to select running on petrol or
LPG.
If, during LPG operation, the same runs
out, the car switches to petrol
automatically and all the bars near the
letters LPG on the display switch off.
This condition persists until the next
LPG refuelling.The engine always starts up on petrol,
with automatic switching to LPG when
the best conditions are achieved
(engine water temperature, minimum
engine rpm limit) for switching to LPG.
REFUELLING
LPG
Maximum refuelling capacity (including
reserve): 38.4 litres. The figure already
takes into account the 80% tank filling
limit and the residual fluid required
for priming; this figure represents the
maximum permitted capacity.In
addition, this value may, in different
refuelling situations, give rise to
variations as a result of: differences
between the supply pressures of
the pumps, pumps with different
supply/stopping specifications,
tank not in reserve condition.
IMPORTANT In order to avoid
inconsistent information by the LPG
gauge on the instrument panel, it is
recommended to refill with at least 10
litres each time.
WARNING
34)Note that in some countries (including
Italy) there are legal restrictions in force
for parking/garaging motor vehicles fuelled
by gas that is denser than air; LPG comes
under this category.
35)Do not switch between the two
operating modes whilst starting the engine.
36)If gas is smelt, switch from LPG
operation to petrol operation and
immediately go to a Fiat Dealership to have
the vehicle checked and possible system
faults excluded.
WARNING
16)The car is equipped with a specifically
designed gaseous LPG injection system:
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. When
towing or lifting the vehicle, follow the
instructions in the main handbook under
the paragraph on "Towing the vehicle"
to prevent damage to the gas system
parts.
17)The system operates at temperatures
ranging between -20°C and 100°C.

KNOWING YOUR CAR

18)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 devices fastening
the cover of the LPG tank, then remove it.
Close the LPG cock rotating the ring nut
clockwise (see "Passive safety / active
safety"). Refit the cover and retighten the
fastening devices.
19)Only use LPG for motor vehicles.
20)It is strictly forbidden to use any
additive in the LPG. Periodically (at least
once every six months) it is advisable to let
the LPG in the tank run out and, at the
first refuelling, to check that it does not
exceed the maximum capacity of 38.4 litres
(reserve included) (with a tolerance of 2
litres excess). If the level is above 38.4 litres
(reserve included) contact a Fiat
Dealership immediately.
21)When switching is requested, metallic
noise from the valves which pressurise
the circuit can be heard. For the switching
logic described above, a delay between the
valve ticking and the switching off of the
instrument panel indication is completely
normal.22)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
instrument panel. In the event of low LPG
levels in the tank or request for high
performance (e.g. overtaking, car fully
laden, steep hills) the system may
automatically switch to petrol operation to
guarantee the engine power requested; the
green warning light on the instrument
panel switches on to indicate this. When
the above conditions are no longer
present, the system automatically restores
LPG operation; the green warning light
switches off. To achieve the automatic
switching described above, make sure that
there is always enough fuel in the petrol
tank.VERSION WITH

INTRODUCTION
The "Natural Power" version features
two fuel systems, one for petrol and
one for natural gas (methane).
CYLINDERS
The car is provided with two cylinders
(total capacity approximately 84 litres)
located under the floor (fig. 56 and
fig. 57) and protected by two specific
guards containing compressed
methane in gaseous state (200 bar
nominal pressure at 15°C).
56F0Y0245C
41

The methane, stored in the cylinders at
high pressure, flows through a
dedicated pipe to reach the pressure
regulator/reduction unit which supplies
the two methane injectors at low
pressure (about 9 bar).
Cylinder capacity: about 14 kg. The
total volume of cylinders is about 84
litres.IMPORTANT In order to avoid
inconsistent information by the
methane gauge on the instrument
panel, it is recommended to refill with at
least 10 litres each time.
Cylinder certification
The cylinders are certified according to
ECE Regulation Procedure no. 110,
and must be inspected every 4 years
according to ECE Regulation Procedure
no. 110 from the car registration date
or in accordance with specific
regulations in individual countries.
The plates provided by the Dealership
with the on board documentation
contain the date for the first inspection
of the cylinders.Methane refuelling
stations are not authorised to refill
the cylinders when the inspection
date has expired.
IMPORTANT If the car has been
registered in a country other than Italy,
the certification data, identification
and inspection procedures for
the methane cylinders should comply
with the legislation in that country.
In any case, remember that the life of
the cylinders is 20 years from the
production date as set out in ECE
Regulation no. 110.SELECTION OF
PETROL/METHANE
SUPPLY TYPE
The engine always starts up on petrol,
with automatic switching to methane
when the best conditions are achieved
(engine water temperature, minimum
engine rpm limit) for switching to
methane.
Therefore, there must always be some
petrol in the tank (at least 1/4 full), in
order not to compromise the operation
of the fuel pump.
If you want to run on petrol, press the
fig. 58 button: this can be done both
when the car is stationary with the
engine running or while driving.
The switching on of the LED located on
the button and of the green warning
light
on the instrument panel
indicates that the switching request has
taken place correctly.

Warning light What it means
DEACTIVATION OF CITY BRAKE CONTROL - "Collision Mitigation" SYSTEM
(for versions/markets, where provided)
The warning light comes on when the City Brake Control - "Collision Mitigation" system is deactivated by
the driver or in the event of automatic deactivation following a temporary system failure. Contact a Fiat
Dealership as soon as possible.
GLOW PLUG PREHEATING (Diesel versions)
This warning light switches on when the key is turned to MAR. It will switch off as soon as the heater plugs
have reached a preset temperature. The engine can be started as soon as the warning light switches off.
IMPORTANT In mild or high ambient temperature conditions, the warning light comes on for a very short
time only.
Glow plug preheating failure
The warning light will flash to indicate an anomaly in the glow plug preheating system. Contact a Fiat
Dealership as soon as possible.
LPG FUEL RESERVE (LPG versions)
(for versions/markets, where provided)
The warning light switches on when the residual quantity of LPG drops below 1/5 of the tank capacity. On
some versions, a specific message is shown on the display.
METHANE RESERVE (Natural Power versions)
(for versions/markets, where provided)
The warning light switches on when the residual quantity of Methane drops below 1/5 of the tank capacity.
On some versions, a specific message is shown on the display.

45)The iTPMS cannot indicate sudden tyre
pressure drops (for example when a tyre
bursts). In this case, stop the vehicle,
braking with caution and avoiding abrupt
steering.
46)The iTPMS system only warns that the
tyre pressure is low: it cannot inflate
them.
47)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect the capacity to drive safely.OCCUPANT
PROTECTION
SYSTEMS
Some of the most important safety
equipment of the car comprise the
following protection systems:
seat belts;
SBR (Seat Belt Reminder) system;
head restraints;
child restraint systems;
Front airbags and side bags.
Read the information given the
following pages with the utmost care. It
is of fundamental importance that the
protection systems are used in the
correct way to guarantee the maximum
possible safety level for the driver and
the passengers.
For the description of the head restraint
adjustment see the "Head restraints"
paragraph in the "Knowing your car"
chapter.
SEAT BELTS
69) 70)
All vehicle seats are equipped with seat
belts with three anchor points and a
retractor.
The reel mechanism operates locking
the belt in the event of sharp braking or
strong deceleration due to an impact.
This allows the seat belt strap to slide
freely and to adapt to the body of
the occupant. In the event of an
accident, the seat belt will lock reducing
the risk of impact inside the passenger
compartment and of being projected
outside the car.
The driver is responsible for respecting,
and ensuring that all the other
occupants of the vehicle also respect,
the local laws in force in relation to
the use of the seat belts.
Always fasten the seat belts before
setting off.
USING THE SEAT BELTS
The seat belt should be worn keeping
the chest straight and rested against
the backrest.
To fasten the seat belts, hold the
tongue A fig. 69 and insert it into the
buckle B, until it clicks into place.
If the belt jams while being removed, let
it rewind for a short stretch, then pull
it out again without jerking.

SAFETY

IMPORTANT NOTES
For towing caravans or trailers the car
must be fitted with an approved tow
hook and an adequate electrical
system. Installation must be carried out
by specialised technicians.
Install any specific and/or additional
door mirrors as specified by the
Highway Code.
Remember that, when towing a trailer,
steep hills are harder to climb, braking
distances increase and overtaking
takes longer depending on the overall
weight of the trailer.
Engage a low gear when driving
downhill, rather than constantly using
the brake.
The weight the trailer exerts on the car
tow hook reduces the car's loading
capacity by the same amount. To make
sure that the maximum towable weight
is not exceeded (given in the vehicle
registration document) account should
be taken of the fully laden trailer,
including accessories and luggage.
Do not exceed the speed limits specific
to each country you are driving in, in
the case of vehicles towing trailers.
In any case, the top speed must not
exceed 100 km/h.Any electric brake (or electric winch,
etc.) should be supplied directly by the
battery through a cable with a section
of at least 2.5 mm
2.
In addition to the electrical branches,
the car electrical system can only
be connected to the supply cable for an
electric brake and to the cable for an
internal light for the trailer, not
exceeding 15 W. For connections, use
the preset control unit with a battery
cable with section not less than 2.5
mm
2.
IMPORTANT The use of auxiliary loads
other than external lights (electric brake,
winch, etc.) must take place with
engine running.
IMPORTANT To install a tow hook
contact a Fiat Dealership.
WARNING
116)The ABS with which the car is
equipped will not control the braking
system of the trailer. Particular caution is
required on slippery roads.
117)Never modify the braking system of
the vehicle to control the trailer brake. The
trailer braking system must be fully
independent of the vehicle’s hydraulic
system.
118)After fitting, screw holes must be
sealed to prevent a exhaust gas inlet.
REFUELLING THE
