2017 FIAT 500L LIVING gas type

SELECTION OF
PETROL/METHANE
SUPPLY TYPE
The 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.

WARNING
105)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
57)Avoid keeping your hand on this lever
between gear change or AUTO/MANUAL
mode requests.
STOP/START
SYSTEM
106) 107)58)
The Start&Stop system automatically
stops the engine each time the car
is stationary and starts it again when
the driver wants to move off.
In this way, the efficiency of the car is
increased, by reducing consumption,
emissions of harmful gases and noise
pollution.
OPERATING MODE
Engine stopping mode
With the car stopped, the engine stops
with gearbox in neutral and clutch
pedal released.
NoteThe engine can only be stopped
automatically after exceeding a speed
of about 10 km/h, to prevent the engine
from being repeatedly stopped when
driving at walking pace.
Restarting the engine
Press the clutch pedal to restart the
engine.
MANUAL SYSTEM

internal trailer light, though not more
than 15 W. To connect, use the preset
control unit with a battery cable with
cross-section no less than 2.5 mm
2.
IMPORTANT The use of auxiliary loads
other than external lights (electric brake,
winch, etc.) must occur with engine
running.
IMPORTANT To install a tow hook
contact a Fiat Dealership.
WARNING
112)The ABS with which the vehicle is
equipped will not control the braking
system of the trailer. Take particular care
when travelling on slippery roads.
113)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.
114)After fitting, fixing screw holes must
be sealed to prevent an exhaust gas inlet.
REFUELLING THE

CLIMATE CONTROL
SYSTEM MAINTENANCE
In winter, the climate control system
must be turned on at least once a
month for about 10 minutes. Before
summer, have the system checked at a
Fiat Dealership.
WARNING
148)Never smoke when performing
operations in the engine compartment.
Flammable gases and fumes may be
present and risk igniting.
149)Be very careful when working in the
engine compartment when the engine
is hot: you may get burnt.
150)If the engine oil is being topped up,
wait for the engine to cool down before
loosening the filler cap, particularly for
vehicles with aluminium cap (where
provided). IMPORTANT: risk of burns!
151)The cooling system is pressurised. If
necessary, only replace the cap with
another original one or the operation of the
system may be adversely affected. Do
not remove the reservoir cap when the
engine is hot: risk of burns.
152)Do not travel with the washer fluid
reservoir empty: the washer operation
is essential for improving visibility. Repeated
operation of the system without fluid could
damage or cause rapid deterioration of
some system components.153)Certain commercial additives for
washer fluids are inflammable. The engine
compartment contains hot components
which may set it on fire.
154)Brake fluid is poisonous and highly
corrosive. In the event of accidental
contact, immediately wash the affected
parts with water and mild soap. Then rinse
thoroughly. Call a doctor immediately if
swallowed.
155)The
symbol on the container
indicates a synthetic brake fluid, which is
different from a mineral fluid. Using a
mineral fluid will damage the special rubber
seals of the braking system beyond repair.
156)Battery fluid is poisonous and
corrosive. Avoid contact with the skin and
eyes. Keep open flames away from the
battery and do not use objects that might
create sparks: risk of explosion and fire.
157)Using the battery with insufficient
fluid irreparably damages the battery and
may cause an explosion.
158)If the vehicle must remain unused for
a long time at a very low temperature,
remove the battery and take it to a warm
place, to avoid freezing.
159)When performing any operation on
the battery or near it, always protect your
eyes with special goggles.
WARNING
69)Be careful not to confuse the various
types of fluids while topping up: they
are not compatible with each other!
Topping up with an unsuitable fluid could
severely damage your vehicle.70)The oil level should never exceed the
MAX mark.
71)Do not add oil with specifications other
than those of the oil already in the engine.
72)PARAFLU
UPanti-freeze fluid is used
in the engine cooling system; use the same
fluid type as that already in the cooling
system when topping up. PARAFLU
UP
may not be mixed with other types of
anti-freeze fluids. In the event of topping up
with an unsuitable product, under no
circumstances start the engine and contact
a Fiat Dealership.
73)Avoid allowing brake fluid, which is
extremely corrosive, to come into contact
with painted areas. Should it happen, wash
immediately with water.
74)Incorrect assembly of electrical and
electronic accessories may cause severe
damage to your vehicle. Go to a Fiat
Dealership if you want to install accessories
(e.g. anti-theft, radio phone, etc.): they will
suggest the most suitable devices and
advise you whether a higher capacity
battery needs to be installed.
