2018 FIAT 500L fuel reserve

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).

Warning light What it means
ESC SYSTEM
(for versions/markets, where provided)
The warning light switches on when the ignition key is turned to MAR, but it should switch off after a few
seconds.
ESC system activation
Intervention by the system is indicated by the flashing of the warning light: it indicates that the car is in
critical stability and grip conditions.
ESC system failure
If the warning light does not switch off, or if it stays on with the engine running, a failure was found on the
ESC system. Contact a Fiat Dealership as soon as possible.
Hill Holder failure
The warning light turns on to indicate a Hill Holder system failure. Contact a Fiat Dealership as soon as
possible
ASR SYSTEM DEACTIVATION
The warning light comes on if the ASR system is deactivated (see "Active safety systems" point of the
"Safety" system).
FUEL RESERVE
The warning light comes on when the amount of fuel in the tank is 7.5 litres or less.
IMPORTANT The warning light will flash to indicate a system failure. If this is the case, go to a Fiat
Dealership to have the system checked.
57

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.
