manualpressing the “immediate
heating” button on the timer again
(flame button 6).
The heating warning light and the
display light are switched off. The fluid
circulation pump keeps working for
approximately two minutes: the heater
can be switched back on again during
this time.
IMPORTANT The parking heater goes
off when battery voltage is low to allow
the vehicle to be started.
IMPORTANT Before turning on the
device, ensure that the fuel level is
above the reserve. Otherwise the
device could lock and require
the assistance of a Fiat Dealership.
Always turn off the heater when
refuelling and near service stations to
avoid the risk of explosion or fire
hazards.
Do not park the vehicle on
inflammable material such as paper,
grass or dry leaves: fire hazard!
The temperature near the heater
should not exceed 120°C (e.g. during
oven painting in a body shop). The
electronic control unit components may
be damaged at higher temperatures.
Whilst the heater is operating with
the engine switched off, it absorbs
energy from the battery; the engine
should therefore be left running for
a while to make sure that the battery is
properly recharged.
To check the coolant level, follow the
instructions in the "Vehicle
maintenance" chapter, "Engine coolant
system fluid" paragraph. The water in
the heating circuit must contain a
minimum percentage of 10% antifreeze.
For maintenance and repairs,
consult only a Fiat Dealership and use
only original parts.
MAINTENANCE
Have the additional heater checked
regularly at a Fiat Dealership (and
always at the start of every winter). This
will guarantee safe and economic
operation of the heater as well as a long
duration.
ADDITIONAL REAR

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.

Fuel storage - Diesel Fuel
133)
In case of the storage of massive
amounts of fuel, good maintenance is
essential. The fuel contaminated with
water favours the proliferation of
"microbes". These microbes create a
"slime" that can clog the filter system
and fuel pipes. Remove water from the
supply tank and regularly replace the
filter pipe.
NOTE When a diesel engine runs out of
fuel, air is blown through the fuel
system.
AdBlue storage (UREA)
AdBlue (UREA) is considered a very
stable product with a long shelf life. If is
stored at temperatures between -12
°C and 32 °C, it can be stored at least
for a year.
Since UREA can freeze at temperatures
at or below -11 °C, the system was
designed to operate also in these cold
environments, thanks to an automatic
heating system which operates when
the engine is started.NOTE When you need to keep the
AdBlue (UREA), it is important to know
that:any container or part that comes in
contact with the UREA must be compatible
with it (plastic or stainless steel). Materials
such as copper, brass, aluminium, iron
or stainless steel is not as susceptible to
corrosion by UREA are to be avoided;
if UREA is spilled from a container,
completely clean the area.
METHANE ENGINES
(NATURAL POWER)
METHANE GAS FILLER
The methane filler is located near the
petrol filler.
To access the filler, unscrew the cap A
fig. 139.The profile of the filler is of the universal
type, compatible with Italian and NGV1
standards.
In some European countries adapters
are considered ILLEGAL (e.g. in
Germany).
For service stations with cubic metre
(m3) nozzles (pressure differential),
to measure the residual pressure in the
cylinder, the non-return valves must
be released by delivering a small
amount of methane.
The other plates (provided with the
vehicle documentation) contain the date
for the first inspection of the cylinders.

WARNING
129)Do not approach naked flames or lit
cigarettes to the fuel tank filler: fire risk.
Keep your face away from the fuel filler to
prevent breathing in harmful vapours.
130)To avoid fuel spillage and the
exceeding of the maximum level, avoid
topping up after filling the tank.
131)Any fuel pumping in portable
containers located on a floor can cause a
fire. Danger of burns. Always put the fuel
container on the ground during filling. Avoid
using contaminated fuel: a fuel
contaminated with water or earth can
cause serious damage to the motor supply.
Proper maintenance of the fuel filter, of
the engine and the fuel tank is essential.
132)If AdBlue overheats for a prolonged
period inside the tank to over 50 ° C (for
example due to direct solar irradiation),
AdBlue can decompose ammonia vapours.
Ammonia vapours have a pungent odour
when the cap of the AdBlue tank is
unscrewed, therefore be careful not to
inhale any ammonia vapours in the tank
outlet. In this concentration, however, the
ammonia vapors are not harmful or
dangerous to health.
133)Do not open the fuel system at high
pressure with the engine running. The
operation of the engine creates a high fuel
pressure. A jet of high-pressure fuel can
cause serious injury or death.
WARNING
35)Only refuel with automotive diesel
complying with the European specification
EN 590. The use of other products or
mixtures may damage the engine beyond
repair and consequently invalidate the
warranty, due to the damage caused. If
you accidentally introduce other types of
fuel into the tank, do not start the engine.
Empty the tank. If the engine has been run
for even an extremely limited amount of
time, you must not only drain the fuel tank,
but the rest of the supply circuit as well.
36)Methane refuelling stations are not
authorised to refill the cylinders when the
inspection date has expired. The check
valve prevents the methane from flowing
back to the fuel filler.
37)If the vehicle has been registered in a
country other than Italy, the certification
data, identification and inspection
procedures for the methane cylinders
should conform to the legislation in that
country. In any case, it should be
remembered that the life of the cylinders is
20 years from the production date as set
out in ECE Regulation no. 110.

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.
