2018 FIAT DUCATO BASE CAMPER fuel reserve

PROCEDURE FOR
NATURAL POWER
VERSIONS
(For versions/markets, where provided)
The various engine cranking methods
are described below:
METHANE tank not on reserve –
petrol tank not empty:
the engine is always started in methane
mode;
METHANE tank empty – petrol tank
not empty:
the engine is forced to start on petrol
and it will not switch to methane until
the methane tank has been filled. At the
same time, the reserve warning light
will turn on and the "REFUELLING
REQUIRED" message will be shown on
the instrument panel display;
METHANE tank not on reserve –
petrol tank empty:
the engine is always started in methane
mode.
17) 18) 19) 20) 21)
WARNING
116)It is dangerous to run the engine in
enclosed areas. The engine consumes
oxygen and engine exhaust contains
carbon dioxide, carbon monoxide and
other toxic gasses.
WARNING
14)It is advisable not to demand maximum
performance from your vehicle (e.g.
excessive acceleration, long distances at
high speeds, excessive intense braking,
etc.) during the initial period of use.
15)When the engine is switched off never
leave the key turned to MAR-ON to prevent
useless current absorption from draining
the battery.
16)If the engine fails to start with a gear
engaged, the potentially dangerous
situation due to the fact that the
transmission is automatically placed in
neutral will be signalled by a buzzer.
17)
If the warning light
flashes for 60
seconds after starting or during an
extended towing period, this indicates a
problem in the glow plug pre­heating
system. Use the vehicle normally if the
engine starts, but contact a Fiat Dealership
as soon as possible. 18)
Remember that the brake servo and
power steering are not operational until the
engine has been started, so you need to
apply much more force than usual to
the brake pedal and steering wheel. 19)
Never bump start the engine by
pushing, towing or coasting downhill. This
could cause fuel to flow into the catalytic
converter and damage it beyond repair. 20)A quick burst on the accelerator before
stopping the engine serves no practical
purpose; it wastes fuel and is especially
damaging to turbocharged engines. 21)
In some cases, when the engine
switches off, the fan could activate for max.
120 seconds.
120
STARTING AND DRIVING

turn the key in the pawl starter in the
ON position (no need to start the
engine);
wait for the warning on the
instrument panel to switch off before
moving the vehicle, the warning light
may stay on for a few seconds to half a
minute. In case of motor start-up and
movement of the vehicle, the warning
light will remain on for a longer period of
time, but there are no problems on the
engine functionality;
if topping up is done with the UREA
tank empty, you have to wait two
minutes before starting the vehicle;
NOTE The driving conditions (altitude,
vehicle speed, load, etc.) determine the
quantity of UREA used by the vehicle.
In order to use the additive for Diesel
Emissions (UREA) correctly, see "Fluids
and lubricants" in the "Technical data".
132)
IMPORTANT
Exceeding the maximum filling level
of the tank UREA, it can cause damage
to the tank and spilling UREA. Please
avoid topping up after filling the tank.
DO NOT EXCEED THE MAXIMUM
LEVEL. The UREA freezes at under -11
° C. Although the system is designed
to operate below the freezing point
of the UREA, it is advisable not to fill the
tank beyond the maximum level
because if the UREA freezes the
system can be damaged.
If the UREA is spilled on painted
surfaces or aluminium, immediately
clean the area with water and use
absorbent material to collect the fluid
that has been spilled on the ground.
Do not try to start the engine if
UREA was accidentally added to the
Diesel fuel tank, this can result in
serious engine damage, contact
Dealership.
Use AdBlue only according to DIN
70 070 and ISO 22241-1. Other fluids
may cause damage to the system: also
exhaust emissions would no longer
comply with the law. The distribution
companies are responsible for the
compliance of their product. Observe
the precautions of storage and
servicing, in order to preserve the initial
qualities. The manufacturer of the
vehicle does not recognise any
guarantee in case of malfunctions and
damage caused to the vehicle due
to the use of urea (AdBlue) not in
accordance with regulations.
Any introduction of diesel fuel inside
the tank AdBlue, causes irreversible
damage to the pumping unit circuit
AdBlue.
Do not add additives to AdBlue. Do
not dilute AdBlue with tap water as
this may damage the system of
purification of exhaust gases.
In case of damage to the sewage
system of exhaust gas resulting from
the use of additives / tap water, the
introduction of diesel fuel, or at least by
not fulfilling the requirements, the
warranty expires.
AdBlue tank topping (UREA) in cold
environments
Since AdBlue (UREA) starts to freeze
around the -11 °C, the vehicle is
equipped with an automatic system of
heating UREA that allows the system to
function properly at temperatures
below -11 °C.
If the vehicle remains idle for a long
period at temperatures below the -11
°C, the UREA in the tank might freeze.
If the tank UREA was filled beyond
the maximum level and freezes, it can
be damaged; for this reason it is
advisable not to exceed the maximum
level of the tank.
Pay extra attention to avoid exceeding
the maximum level when you use
portable containers for topping up.

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.

(****) When the vehicle is used in particularly harsh weather conditions, we recommend using a 60-40 mixture of PARAFLU
UPand demineralised water.
IMPORTANT Note that when using a fuel like methane, the range is extremely variable because in addition to the vehicle
maintenance and driving conditions it also depends on the temperature of the gas in the cylinder. The methane actually heats
up during the refuelling and cools down whilst driving, undergoing variations in pressure that reduce the quantity that can
be used.
