2018 FIAT 500L engine

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.

KNOWING YOUR CAR

To guarantee switching in full safety, the
actual change to the chosen fuel
system takes place depending on the
car usage conditions; it may not
therefore be immediate.
In addition, when starting at outside
temperatures below approximately
-10°C, the switching times from petrol
to methane increase to allow the
pressure regulator/reduction unit to
heat up.
WARNING
37)The car is equipped with a high-
pressure methane system designed to
operate at 200 rated bar. It is dangerous to
force the system to run at higher
pressures. When towing or lifting the car,
follow the instructions in the "Towing
the car" paragraph to prevent damage to
the methane system parts. If there is a fault
in the methane system, only contact a
Fiat Dealership. Do not modify
configuration or components of the
methane system; they have been designed
exclusively for this car. The use of other
components or materials could cause
malfunctions and prejudice safety.38)When oven painting, the cylinders must
be removed from the vehicle and
subsequently refitted by a Fiat Dealership.
Although the methane system has
numerous safety features, it is advisable to
close the manual cocks for the cylinders
every time the car is not in use for a long
period, transported on other cars or moved
in an emergency as a result of a fault or
accident.
39)Do not switch between the two
operating modes whilst starting the engine.
40)If gas is smelled, switch from methane
operation to petrol operation and
immediately go to a Fiat Dealership to have
the vehicle checked and possible system
faults excluded.
WARNING
23)If, during methane operation, the same
runs out, the car switches to petrol
automatically and all the bars near the
letters CNG on the display switch off. This
display remains until the next methane
refuelling.
24)Regardless of the last fuel system
used, at the following engine starting, after
the initial petrol stage, the system will
automatically switch to methane.
25)When switching from petrol to methane
is requested, a metal noise from the valves
which pressurise the circuit can be heard,
as it happens while starting the car. For the
switching logics described above, a delay
between the valve ticking and the switching
off of the green warning light
is
absolutely normal.26)In particular usage conditions, such as
starting and operation at low ambient
temperature, the system may switch
temporarily to petrol operation, without
indicating the performed switching. In the
event of low methane 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 icon
switches
on to indicate this. When the above
conditions are no longer present, the
system automatically restores methane
operation. The green warning light
turns
off. To achieve the automatic switching
described above, make sure that there is
always enough fuel in the petrol tank.
27)The other plates (provided with the
vehicle documents) show the date when
the first cylinder inspection/test is due.
Methane refuelling stations are not
authorised to refill the cylinders when the
inspection date has expired.

DASHBOARD AND INSTRUMENT PANEL
The instrument background colour and type may vary according to the versions.
A. Speedometer / B. Digital fuel level gauge / C. Display / D. Digital engine coolant thermometer / E. Tachometer
The warning lights on the instrument panel may change according to the version/trim level (e.g. LPG, Natural Power, Dualogic
gearbox, etc.) of the vehicle. The
warning light is present on Diesel versions only. On Diesel versions, the maximum engine
speed (red range on the rev counter) corresponds to 7000 rpm.

TRIP COMPUTER
The Trip computer is used to display
information on car operation when the
key is turned to MAR.
The Trip computer comprises:
Instantaneous info(except LPG
and Natural Power versions): display of

“Average speed”
48
KNOWING THE INSTRUMENT PANEL
“Trip A” and “Trip B” monitor the car's
"complete missions" (trips) separately
from each other. The “Trip B” function
may be excluded.

The "Range" is also calculated and
displayed with the car at a standstill
and the engine running.
Reset “Trip A” / “Trip B”
Both functions can be reset (reset
means start of a new journey). To reset
the values, press and hold down the
OKbutton on the steering wheel (see
"Control buttons" section). The reset
only applies to the values displayed
(“Trip A” or “Trip B”).
LPG and Natural Power versions
Only the “Travel Distance”, “Travel
Time” and “Average speed” values are
displayed on LPG and Natural Power
versions.
NOTE “Range” and “Current
Consumption" parameters cannot be
reset.

Warning light What it means
EBD FAILURE
The warning light switches on when the ignition key is turned to MAR, but it should switch off after a few
seconds.
The simultaneous switching on of the
(red) and(amber) warning lights with the engine on
indicates either a failure of the EBD system or that the system is not available. In this case, the rear wheels
may suddenly lock and the vehicle may swerve when braking sharply. On certain versions a dedicated
message is displayed.
Drive very carefully to the nearest Fiat Dealership to have the system inspected immediately.
51

Warning light What it means
ENGINE COOLANT TEMPERATURE TOO HIGH
The warning light turns on when the engine is overheated. On some versions the display shows the
dedicated message.
In normal driving conditions: stop the car, switch off the engine and check that the water level in the
reservoir is not below the MIN mark. In this case, wait for the engine to cool down, then slowly and
carefully open the cap, top up with coolant and check that the level is between the MIN and MAX marks on
the reservoir itself. Also check visually for any fluid leaks. If, when restarting, the warning light (or display
symbol) switches on again, contact a Fiat Dealership.
If the car is used under demanding conditions (e.g. in high-performance driving):slow down and, if
the warning light stays on, stop the car. Wait for 2 or 3 minutes with the engine running and slightly
accelerated to further favour the coolant circulation. Then stop the engine. Check that the coolant level is
correct as described above.
IMPORTANT On demanding routes, it is advisable to keep the engine on and slightly accelerated for a few
minutes before stopping it.
