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.

TOWING TRAILERS
IMPORTANT NOTES
The vehicle must be provided with a
type-approved tow hook and adequate
electrical system to tow caravans or
trailers. Installation should be carried
out by specialised personnel who
will issue the required papers for
travelling on roads.
Install any specific and/or additional
door mirrors as specified by the
Highway Code.
Remember that when towing a trailer,
steep hills are harder to climb, the
braking spaces increase and overtaking
takes longer depending on the overall
weight.
Engage a low gear when driving
downhill, rather than constantly using
the brake.
The weight of the trailer on the vehicle
tow hook will reduce the loading
capacity of the vehicle by the same
amount. Consider the weight of the
trailer fully laden, including accessories
and luggage, to make sure you do
not exceed the maximum towable
weight (shown on the vehicle
registration document).Do not exceed the speed limits specific
to each country you are driving in, in
the case of vehicles towing trailers.
In any case, the top speed must not
exceed 100 km/h.
You are advised to fit a suitable
stabiliser to the trailer drawbar.
In the vehicles equipped with parking
sensors, after fitting the tow hook
malfunctioning warnings may be
displayed, as some parts (tow bar, ball
tow hook) may be within the sensor
detection range. In this case the
detection range must be adjusted or
the parking assistance function must be
deactivated.
In vehicles equipped with "Comfort-
matic" transmission, make sure that the
gearbox is in neutral (N) (checking that
the vehicle moves when pushed) and
proceed in the same way as for towing
a normal vehicle with manual
transmission. If the gearbox cannot be
put in neutral, do not tow the vehicle
and contact a Fiat Dealership.
137) 138)
INSTALLING THE TOW
HOOK
The towing device should be fastened
to the body by specialised technicians
according to any additional and/or
integrative information supplied by the
Manufacturer of the device.
The towing device must meet current
regulations with reference to Directive
94/20/EC and subsequent
amendments.
For any version the towing device used
must match the towable weight of the
vehicle on which it is to be installed.
For the electric connection a standard
connector should be used which is
generally placed on a special bracket
normally fastened to the towing device,
and a special ECU for external trailer
light control must be installed on the
vehicle. For the electrical connection, 7
or 13 pin 12 V DC connections are to
be used (CUNA/UNI and ISO/DIN
Standards). Follow the instructions
provided by the vehicle manufacturer
and/or the tow hitch manufacturer.
Any electric brake (or electric winch,
etc.) should be supplied directly by the
battery through a cable with a section
of at least 2.5 mm
2.
IMPORTANT Electric brakes or other
devices must be used with engine
running.

PROLONGED
VEHICLE INACTIVITY
If the vehicle needs to be off the road
for longer than one month, the following
precautions must be taken:
park the vehicle indoors in a dry
and, if possible, well-ventilated place;
engage a gear;
check that the handbrake is not
engaged;
disconnect the negative battery
terminal; if the vehicle is equipped with
a battery disconnection function
(disconnector), see the description of
the procedure in the "Controls"
paragraph in the "Dashboard and
controls" section;
clean and protect the painted parts
using protective wax;
clean and protect the shiny metal
parts using special compounds
available commercially;
sprinkle talcum powder on the
windscreen and rear window wiper
rubber blades and lift them off the
glass;
slightly open the windows;
cover the vehicle with a piece of
fabric or perforated plastic sheet. Do
not use compact plastic tarpaulins,
which prevent humidity from
evaporating from the surface of the
vehicle;
inflate tyres to +0.5 bar above the
standard specified pressure and check
it at intervals;
do not drain the engine cooling
system.
IMPORTANT If the vehicle is equipped
with an alarm system, switch off the
vehicle alarm with the remote control.
IMPORTANT After turning the ignition
key to STOP and having closed the
driver side door, wait at least one
minute before disconnecting the
electrical supply from the battery. When
reconnecting the electrical supply to
the battery, make sure that the ignition
key is in the STOP position and the
driver side door is closed.
