2015 FIAT 500L LIVING fuel pressure

LPG TANKThe car has a (pressurised) tank A fig.
49 for collecting LPG in a liquid state. It
is located in the spare wheel
compartment with suitable protection.LPG tank certificationThe LPG tank is certified in accordance
with the regulations in force.In Italy, the tank has a life of 10 years
starting from the vehicle 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 any case, when the time limit
in the individual country has run out,
contact a Fiat Dealership to have the
tank replaced.
SELECTION OF
PETROL/LPG SUPPLY
TYPEThe (petrol/LPG switch) button A fig. 50
allows drivers to select petrol or LPG
operation.
If, during LPG operation, the same runs
out, the vehicle switches to petrol
automatically and all the bars of the
digital gauge on the display switch off,
next to the LPG warning. 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.
SUPPLIES
LPGMaximum refuelling capacity (reserve
included): 38.4 litres. The figure already
takes into account the 80% tank filling
limit and the residual fluid required
for correct priming and it is the
maximum permitted capacity. In
addition, after different refuelling
processes, this figure could vary due to
differences between the network pump
supply pressures, pumps having
different supply/locking features, tank
not completely run out of fuel.

VERSION WITH
METHANE SYSTEM
(Natural Power)
38) 39) 40) 41)23) 24) 25) 26) 27)
INTRODUCTIONThe "Natural Power" version features
two fuel systems, one for petrol and
one for natural gas (methane).METHANE CYLINDERSThe vehicle is equipped with two
cylinders (total capacity about 84 litres)
located under the floor of the vehicle
(fig. 51 and fig. 52) protected by two
special guards filled with methane
at compressed gaseous state (rated
pressure 200 bar at 15°C).
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).
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 certificationThe cylinders are certified in
accordance with ECE Regulation no.
110, and they must be inspected,
according to the Procedure of the ECE
Regulation no. 110, every 4 years
from the vehicle 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 vehicle has been
registered in a country other than Italy,
the certification data, identification
and inspection procedures for
the methane cylinders should conform
to 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 TYPEThe engine normally runs on methane
except during starting, when it runs
on petrol. Switching to methane is
automatic.
If you want to run on petrol, press
button A fig. 53: this operation is
allowed both with car at a standstill and
engine running and also 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.
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
38)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 main
handbook under the paragraph on "Towing
the car" to prevent damage to the
methane system parts. If there is a
problem with 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 reduce safety.
39)In the case of painting in an oven, the
cylinders should be removed from the
vehicle and refitted later 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 vehicle is not in
use for a long period, transported on other
transport means or moved in an
emergency as a result of a breakdown or
accident.
40)Do not switch between the two
operating modes whilst starting the engine.41)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 vehicle switches to petrol
automatically and all the bars of the digital
gauge on the display switch off, next to
the CNG warning. This displaying 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 and when starting the engine,
a metal noise is heard from the valves
which pressurise the circuit. As a result of
the switching logic described above, the
delay between the ticking of the valve and
the switching off of the green warning
light
is entirely normal.

Amber warning lights
Warning light What it means
iTPMS
(for versions/markets, where provided)
iTPMS failure/iTPMS temporarily deactivated
The warning light flashes for about 75 seconds and then stays on constantly (together with a message on
the display) to indicate that the system is temporarily deactivated or faulty. The system goes back to normal
operation when the operating conditions allow it. If this is not the case, carry out the "Reset" procedure
after restoring the normal operating conditions.
If the malfunction warning persists, contact a Fiat Dealership as soon as possible.
Tyre pressure low
The warning light switches on continuously to indicate that the tyre pressure is lower than the
recommended value and/or that slow pressure loss is occurring. In these cases, optimal tyre duration and
fuel consumption may not be guaranteed. It is advisable to restore the correct pressure value (see the
"Wheels" paragraph in the "Technical specifications" section).
Once the normal operating conditions of the vehicle are restored, carry out the "Reset" procedure.
IMPORTANT Do not continue driving with one or more flat tyres as handling may be compromised. Stop
the vehicle, avoiding sharp braking and steering.City Brake Control - "Collision Mitigation" SYSTEM DEACTIVATED
(for versions/markets, where provided)
The warning light comes on when the City Brake Control - "Collision Mitigation" system is deactivated
through the Setup menu. On some versions, the activation/deactivation of the system is indicated by a
message shown on the display.

Warning light What it means
GENERIC FAILURE INDICATION
The warning light switches on in the following circumstances. In these cases contact a Fiat Dealership to
have the fault fixed as soon as possible:
❒Limit speed exceeded: on some versions, when the limit speed is exceeded, a message and a symbol
are displayed, along with a buzzer;
❒Fuel cut-off system intervention/failure
❒External light failure: the warning light switches on when a failure is detected in one of the following lights:
daytime running lights (DRL) (where provided)/side lights/direction indicator/rear fog light/reversing light/
number plate light/brake lights (for versions with multifunction display only). The fault relating to these lights
could be: one or more blown bulbs, a blown protection fuse or a break in the electrical connection;

37)Sensor operation may also be
compromised by the presence of dust,
condensation, dirt or ice on the
windscreen, by traffic conditions (e.g.
vehicles that are driving not aligned with
yours, vehicles driving in a transverse
or opposite way on the same lane, bend
with a small radius of curvature), by road
surface conditions and by driving
conditions (e.g. off-road driving). Make sure
the windscreen is always clean. Use
specific detergents and clean cloths to
avoid scratching the windscreen. The
sensor operation may also be limited or
absent in some driving, traffic and road
surface conditions.
38)Projecting loads on the roof of the
vehicle may interfere with the correct
operation of the sensor. Before starting
make sure the load is correctly positioned,
in order not to cover the sensor operating
range.
39)If the windscreen must be replaced
due to scratches, chipping or breakage,
contact exclusively a Fiat Dealership.
Do not replace the windscreen on your
own, risk of malfunction! It is advisable to
replace the windscreen if it is damaged
in the area of the laser sensor.
40)Do not tamper with nor operate on the
laser sensor. Do not close the openings
in the aesthetic cover located under the
interior rear view mirror. In the event of
a sensor failure, contact a Fiat Dealership.
41)If you are driving on roads close to
trees with protruding branches it is
advisable to deactivate the system to
prevent the branches at the height of the
bonnet or the windscreen from interfering
with the system.42)Do not cover the operating range of the
sensor with stickers or other objects. Also
pay attention to other objects on the
bonnet (e.g. a layer of snow) and make
sure they do not interfere with the light
emitted by the laser.
43)If a trailer or a vehicle is towed, the
system must be deactivated with the
display Setup Menu.
44)If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
45)iTPMS does not relieve the driver from
the obligation to check the tyre pressure
every month; it is not to be considered
a system to replace maintenance or a
safety system.
46)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.
47)The iTPMS only warns that the tyre
pressure is low: it is not able to inflate
them.
48)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect the capacity to drive safely.
49)Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even
though it is higher than the prescribed
value, but repeat the check when tyres are
cold.
OCCUPANT

operators.IMPORTANT Depending on the country,
there are various types of adapters for
LPG refuelling pumps. Filler adapter,
supplied with the vehicle and located in
a special case, is specifically designed
for the country in which the vehicle is
sold. If you are in a different country,
find out what type of adaptor is used
there.
Natural Power versions
62)
For refuelling, open the flap A fig. 103,
undo cap B turning it counterclockwise
and reach the filler C.
The profile of the filler for refilling is the
universal type compatible with Italian
and NGV1 standards. In some
European countries adapters are
considered ILLEGAL (e.g. in Germany).
WARNING
115)Do not apply any object/plug to the
end of the filler which is not provided
for the vehicle. Using non-approved
objects/plugs may cause pressure
increase in the tank, leading to dangerous
conditions.
116)Do not get close to the filler of the
tank with naked flames or lit cigarettes: risk
of fire. Do not get too close to the filler
with your face, in order not to inhale
harmful vapours.
117)Do not use a mobile phone near the

120)Vehicle handling is modified with the
space-saver wheel fitted. Avoid violent
acceleration and braking, abrupt steering
and fast cornering. The overall duration
of the space-saver wheel is about 3000
km, after which the relevant tyre must be
replaced with another one of the same
type. Never install a standard tyre on a rim
that is designed for use with a space-saver
wheel. Have the wheel repaired and refitted
as soon as possible. Using two or more
space-saver wheels at the same time
is forbidden. Do not grease the threads of
the stud bolts before fitting them: they
might slip out when driving.
121)The jack shall only be used for raising
the car model it has been supplied with.
Never use the jack for other purposes,
such as raising other car models. Never
use the jack for repair operations under the
vehicle. Incorrect positioning of the jack
may cause the vehicle to fall. Do not use
the jack for loads higher than the one
shown on its label. The space-saver wheel
cannot be fitted with snow chains. If a
front (drive) tyre is punctured and chains
are needed, use a standard wheel from the
rear axle and install the space-saver wheel
on the rear axle. This way, with two
standard front driving wheels, you can
install the snow chains on them.
122)Incorrect hub cap assembly may
cause it to come off when the vehicle is
moving. Never tamper with the inflation
valve. Never introduce tools of any kind
between rim and tyre. Check tyre and
space-saver wheel pressures regularly,
complying with the values given in the
"Technical specifications" chapter.123)At the end of the operation of
raising/locking the spare wheel, the ignition
key must be extracted, taking care not to
turn it in the wrong direction to facilitate the
extraction of the key itself, to prevent the
attachment device from being released and
the wheel assembly not being securely
retained.
WARNING
63)Contact a Fiat Dealership as soon as
possible to have the correct tightening
of the wheel stud bolts checked.
