fuel tank capacity FIAT DUCATO 2018 Owner handbook (in English)

What it means What to do
amberUREA INJECTION SYSTEM FAILURE
The warning light switches on, together with a
dedicated message on the display (for versions/
markets, where provided) if a fluid not conforming with
the nominal characteristics is inserted o if an average
consumption of UREA over 50% is detected.Contact a Fiat Dealership as soon as possible.
If the fault is not resolved, a further warning will be
given at the following remaining km before the vehicle
restart will be prevented:
400 km
320 km
240 km
When 200 km will remain to prevent the engine restart,
a continuous dedicated message will appear on the
dashboard (for versions/markets where provided)
accompanied by a buzzer sound
amberABS FAILURE
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few
seconds.
The warning light switches on to indicate a system
fault. In this case the braking system maintains its
efficiency unaltered but without the advantage of the
ABS system. The display shows the dedicated
message.Drive carefully and contact a Fiat Dealership as soon
as possible.
amberFUEL RESERVE
The warning light switches on when the ignition key is
turned to MAR, but it should switch off after a few
seconds. The warning light switches on when there
are about 10-12 litres of fuel (for versions with tank
capacity 90-120 l) or 10 l (for versions with tank
capacity 60 l) remaining in the tank.The warning light will blink to indicate a system fault. If
this is the case, go to a Fiat Dealership to have the
system checked.

KNOWING THE INSTRUMENT PANEL

REFUELLING THE
VEHICLE
IN BRIEF
Stop the engine before refuelling.
PETROL ENGINES
Only usepetrol with an octane number
(RON) no lower than 95 (EN228
specification).
DIESEL ENGINES
Refuel the vehicle exclusively with diesel
for motor vehicles in compliance with
European specification EN590.
OPERATION AT LOW
TEMPERATURES
When using or parking the vehicle for a
long time in the mountains or cold
areas, it is advisable to refuel using
locally available diesel fuel. In this case,
it is also advisable to keep the tank
over 50% full.
35)
TANK CAPACITY
To ensure that you fill the tank
completely, top up twice after the first
click of the fuel supply gun. Further
top-ups could cause faults in the fuel
feeding system.
FUEL TANK CAP
To refuel, open the flap A fig. 137
located on the left side of the vehicle
and then unscrew the cap B fig. 137 by
turning it anticlockwise.
For versions / markets where provided,
insert the ignition key in the lock of
the cap. Turn the key counter-clockwise
and remove the cap by gripping the
key. Do not remove the key from the
cap during refuelling. While refuelling,
the cap can be hung on the flap A (fig.
137).The sealing may cause a slight pressure
increase in the tank. A little breathing
off, while slackening the cap is
absolutely normal.
In case of loss or damage to the fuel
tank cap, make sure that the
replacement cap is for the appropriate
vehicle.
Tighten the cap of the fuel tank filler
until you hear a "click". This sound
shows that the cap of the fuel tank filler
is properly tightened.
For versions / markets where provided,
turn the key clockwise until it stops. It
is not necessary to apply an additional
load on the key to complete the
tightening of the cap. Only in the case
where the cap has been tightened
properly, it will be possible to remove
the ignition key from the cap.
After each refuelling, make sure the fuel
filler cap is securely tightened.
IMPORTANT
When the gun distributor fuel "snaps" or
interrupts the supply, the tank is nearly full
and you can run two additional top-ups
after shooting automatic.

ADDITIVE FOR
DIESEL EMISSIONS
ADBLUE (UREA)
System description
The vehicle is equipped with an UREA
fuel injection system and a Selective
Catalytic Reduction catalyst to meet the
emission standards.
These two systems ensure compliance
with the diesel emissions requirements;
at the same it maintains fuel saving
levels, driveability, torque and power.
For the system messages and warnings
refer to the "Warning lights and
messages" paragraph in the "Knowing
the instrument panel" section.
Notes
When you stop the vehicle you
could hear a distinct click coming from
under the vehicle due to the UREA
injection system, this is normal.
The UREA injection system pump
continues to operate for a short period
of time after the engine is switched
off, to purge the circuit. This is normal,
and you can still hear its noise from
under the vehicle.
VERSION WITH
METHANE SYSTEM
(Natural Power)
38) 39)
INTRODUCTION
The "Natural Power" version of the Fiat
Ducato features two fuel system, one
primary natural gas (methane) system
and one emergency petrol system.
METHANE CYLINDERS
The vehicle is equipped with five
cylinders (total capacity of about 218
litres) located under the vehicle floor
and protected by two special shields.
The cylinders are the tank that contains
the methane in its compressed
gaseous state (nominal pressure of 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 4 methane injectors at
low pressure (about 6 bar).
The cylinders must be inspected, in
accordance with ECE Regulation
Procedure no. 110, every 4 years
from the vehicle registration date or
in accordance with specific
regulations in individual countries.IMPORTANT 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.
FUEL SWITCHING
LOGICS
Management of switching between the
two different fuel supplies is fully
automatic, and carried out by the
engine control unit.
When the residual amount of methane
drops below 1/5 of the cylinder
capacity, the lowest level and the edges
of the other levels flash to indicate the
reserve state and that refuelling fig. 140
is required.
If the methane runs out, it is
automatically switched to petrol; on the
display, all the empty segments stop
flashing and then the
indicator near
the CNG icon fig. 141 turns on.
Having reached the reserve methane
pressure threshold, and completely
filled the methane tank, the system
forces the switch to petrol for 5
seconds, with the aim of keeping the
petrol fuel supply system fully efficient.
138
STARTING AND DRIVING

The general recommendation is to
avoid emptying the petrol tank
completely, as this may lead to a
risk for the driver:
After the METHANE level has
dropped below the reserve threshold,
the vehicle will continue to run on petrol
until it runs out;
the vehicle has run out of petrol
during a previous mission and while
running on METHANE it has reached
the METHANE reserve pressure
threshold: in this case, the system
forces switching to petrol and the
vehicle turns off while it is in motion.NOTE Make sure that the key is in the
OFF position when refuelling with
methane. If, in fact, the system has
already forced running on petrol and
you refuel with methane with the key in
the ON position, the engine will
continue running on petrol until the next
time it is started.
RESTRICTIONS ON USE
Passing from running on methane to
running on petrol causes the maximum
speed to be limited to 90 km/h;
therefore, after the first methane reserve
indication, it is advisable to refuel and
after the second indication of gaseous
fuel running out (double beep), avoid
"risky" conditions such as overtaking at
high speed on the motorway.
Petrol operation is for emergency only.
In order to guarantee good
independence, even where there is
limited tank capacity, performance is
limited such as speed or, as for
take-off, acceleration (particularly uphill).
As such, before embarking on
demanding journeys and/or routes, in
terms of load or road conditions, it
is advisable to ensure that the gaseous
fuel canister is full.
WARNING
38)Fiat Ducato Natural Power is equipped
with a high pressure methane system
designed to run at 200 bar. It is dangerous
to stretch the system with higher
pressures. If there is a problem with the
methane system, only contact a Fiat
Dealership. Do not alter the methane
system configuration or components; they
are designed exclusively for the Fiat
Ducato Natural Power. The use of other
components or materials could cause
malfunctions and prejudice safety.
39)When oven painting, the cylinders must
be removed from the vehicle and refitted
by a Fiat Dealership. Although the methane
system has numerous safety features, it is
advisable to close the manual tap on the
cylinders every time the vehicle is not
in use for a long period, transported on
other vehicles or moved in an emergency
as a result of a breakdown or accident.
