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)
37) 38)
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).
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. 119
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. 120 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.

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.

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.
