What it means What to do
amberGENERAL FAILURE INDICATION
(Versions with multifunction display)
The warning light turns on in the following
circumstances:
If the fuel inertia cut-off switch is activated
Light failure (rear fog lamps, direction indicators,
brake lights, number plate lights, side lights, daytime
running lights, main beam automatism, trailer direction
indicators, trailer side lights)The failure relating to these lights could be: one or
more blown bulbs, a blown protection fuse or a break
in the electrical connection.
Airbag warning light failure (generic failure warning
light flashing)In this case, the warning light may not indicate
problems with the restraint systems. Before
continuing, contact a Fiat Dealership to have the
system checked immediately.
Rain sensor failure
Diesel filter sensor failure
Trailer connection failure
Audio system failure
Engine oil pressure sensor failure
Parking sensor failure
Water in diesel fuel filterContact a Fiat Dealership as soon as possible to have
the fault fixed.
FOR VERSIONS WITH A MULTIFUNCTION DISPLAY,
THE WARNING LIGHT ALSO TURNS ON IN THE
FOLLOWING CIRCUMSTANCES:
Engine oil level sensor failure
Insufficient engine oil level
71

What it means What to do
amberTPMS SYSTEM
TPMS failure
The warning light flashes for about 75 seconds and
then stays on constantly (along with a dedicated
message on the display) to indicate that the system is
temporarily deactivated or faulty.In this case, contact a Fiat Dealership as soon as
possible
Tyre pressure low
The warning light turns on to indicate that the pressure
of one or more tyres is lower than the recommended
value and/or that slow pressure loss is occurring. In
these circumstances, optimal tyre duration and fuel
consumption may not be guaranteed.In this case it is advisable to restore the correct
pressure value.
IMPORTANT Do not continue driving with one or more
flat tyres as vehicle handling may be compromised.
Stop the vehicle, avoiding sharp braking and steering.
WARNING
48)The driving speed must always be suitable for traffic and weather conditions and the driver must always comply with the Highway Code.
The engine may be stopped if the DPF light is on; however, repeated interruption of the regeneration process may result in premature
deterioration of the engine oil. For this reason, always wait until the warning light switches off before stopping the engine as described above.
It is not advisable to complete DPF regeneration with the vehicle stationary.
WARNING
9)If, when the ignition key is turned to MAR, thewarning light does not switch on, switches on constantly or flashes when driving (on
certain versions together with the message on the display), contact a Fiat Dealership as soon as possible.
10)During regeneration, the fan could be operated.
74
KNOWING THE INSTRUMENT PANEL

The TPMS continues to advise the
driver of the low tyre pressure condition
until this is corrected; the warning
continues until the pressure
corresponds or exceeds the pressure
prescribed for the cold tyres. When the
low tyre pressure check warning light
turns on continuously, the inflation
pressure must be adjusted until it
reaches the pressure prescribed for
cold tyres. After the automatic update
of the system, the tyre pressure control
warning light switches off. You may
need to drive the vehicle for about 20
minutes at a speed higher than 20
km/h to allow the TPMS to receive this
information.
NOTE
The TPMS does not replace the
normal tyre maintenance service and
does not indicate any fault in a tyre.
Therefore, the TPMS should not be
used as pressure switch while adjusting
the tyre inflation pressure.
Driving with insufficient tyre pressure
causes their overheating and can
result in tyre failure. The low inflation
pressure reduces fuel efficiency and
tyre tread life and may also affect
handling and braking performance of
the vehicle.
The TPMS does not replace the
correct tyre maintenance. It is up to the
driver to maintain the correct tyre
pressure level measuring it with
a suitable pressure switch. This is
necessary even if the decrease in the
inflation pressure value does not cause
the tyre pressure control warning light
to switch on.
The TPMS warns the driver of any
condition of insufficient tyre pressure. If
this drops below the insufficient
pressure limit for any reason including
low temperature and normal pressure
loss of the tyre.
The seasonal temperature changes
affect tyre pressure.
The TPMS uses wireless devices with
electronic sensors mounted on the
wheel rims to constantly monitor the
value of tyre pressure. The sensors
mounted on each wheel as part of the
valve stem transmit various information
of the tyres to the receiver module, in
order to calculate the pressure.
IMPORTANT Monitoring and
maintaining the correct pressure in all
four tyres are particularly important.Tyre pressure monitoring system
low pressure warnings
The system warns the driver if one or
more tyres are flat by turning on the
warning light on the instrument
panel (together with a warning message
and an acoustic signal).
In this case, stop the vehicle as soon as
possible, check the inflation pressure
of each tyre and inflate to the cold tyre
pressure value prescribed for the
vehicle. The system will automatically
update and after receiving the tyre
pressure update the tyre pressure
control warning light switches off. You
may need to drive the vehicle for about
20 minutes at a speed higher than 20
km/h to allow the system to receive this
information.
TPMS operation faults
The system fault is indicated by the
corresponding warning light
, which
first flashes for 75 seconds and then
stays on continuously. This can occur in
any of the following situations:
interference caused by electronic
devices or radio frequency emissions
similar to those of the TPMS sensors.
Application of tinted films which
interfere with the signals of the radio
waves.
91

Presence of snow or ice on the
wheels or the wheel arches.
Use of snow chains.
Use of wheels/tyres not equipped
with TPMS sensors.
The space-saver wheel is not
equipped with the tyre pressure control
sensor. Therefore, the tyre pressure is
not controlled by the system.
If the space-saver wheel replaces a
tyre with a pressure lower than the
insufficient pressure limit, an acoustic
signal will be emitted and the
warning light will turn on at the next
start-up.
When the original tyre is repaired or
replaced and it is mounted back on
the vehicle to replace the space-saver
wheel, the TPMS will update
automatically and the warning light will
switch off, provided that the pressure of
none of the four tyres is below the
insufficient pressure limit. You may need
to drive the vehicle for about 20
minutes at a speed higher than 20
km/h to allow the TPMS to receive this
information.
WARNING
69)The TPMS is optimised for the original
tyres and wheels provided. TPMS
pressures and alerts have been defined
according to the size of the tyres mounted
on the vehicle. Using equipment with
different size, type or kind may cause
irregular system operation or sensor
damage. Non-original spare wheels can
damage the sensor. Do not use tyre
sealant or balancing weights if the vehicle
is equipped with TPMS as these may
damage the sensors.
70)If the system signals a pressure
decrease on a specific tyre, it is
recommended to check the pressure on all
four tyres.
71)The TPMS does not relieve the driver
from the obligation to check the tyre
pressure every month; it is not even to be
considered a replacing system for
maintenance or a safety system.
72)Tyre pressure must be checked with
tyres cold. Should it become necessary for
whatever reason to check pressure with
warm tyres, do not reduce pressure even
though it is higher than the prescribed
value, but repeat the check when tyres are
cold.
73)The TPMS cannot indicate sudden tyre
pressure drops (for example when a tyre
bursts). In this case, stop the vehicle,
braking with caution and avoiding abrupt
steering.74)The system only warns that the tyre
pressure is low: it is not able to inflate
them.
75)Insufficient tyre inflation increases fuel
consumption, reduces the tread duration
and may affect your ability to drive the
vehicle safely.
76)Always refit the valve stem cap after
inspecting or adjusting tyre pressure. This
prevents dampness or dirt from entering
the valve stem and thus the pressure
control sensor from being damaged.
77)The tyre repair kit (Fix&Go) provided
with the vehicle (for versions/markets,
where provided) is compatible with the
TPMS sensors; using sealants not
equivalent with that in the original kit may
adversely affect its operation. If sealants
not equivalent with the original ones are
used, it is recommended to have the
TPMS sensor operation checked by a
qualified repair centre.

SAFETY

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.

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.
137

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.
