6)Never extract the key while the vehicle is
moving. The steering wheel will
automatically lock as soon as it is turned.
This also applies to cases in which the
vehicle is towed.7)It is absolutely forbidden to carry out any
after-market operation involving steering
system or steering column modifications
(e.g.: installation of anti-theft device) that
could badly affect performance and safety,
cause the lapse of warranty and also
result in non-compliance of the vehicle with
type approval requirements.
THE FIAT CODE
SYSTEM
IN BRIEF
This is an electrical engine locking
system which increases protection
against attempted theft of the vehicle.
It is automatically activated when
the key is removed from the ignition
device.
Each key contains an electronic
device which modulates the signal
emitted during ignition by an antenna
built into the ignition device. The
signal, which changes each time the
engine is started, is the “password”,
by means of which the control unit
recognises the key and enables
starting.

VERSION WITH
METHANE SYSTEM
(Natural Power)
41) 42) 43)
8) 9) 10)
INTRODUCTION
The Fiat Doblò Natural Power version
features two fuel supply systems,
one for petrol and one for natural gas
(methane).
Selecting the type of fuel supply
Fiat Doblò Natural Power is configured
to run normally on methane.
When the methane is running out and
the pressure in the cylinder is close
to the correct operating limit, the
system automatically switches to petrol
operation.
The engine always starts up on petrol,
with automatic switching to methane
when the best conditions are achieved
(engine water temperature, minimum
engine rpm limit) for switching to
methane.
Therefore, there must always be some
petrol in the tank (at least 1/4 full), in
order not to compromise the operation
of the fuel pump.
For this reason there must always
be petrol in the tank.The petrol/methane switch fig. 87,
amongst the controls in the dashboard,
makes it possible to select petrol
operation. The system does not switch
automatically to methane operation if
the petrol runs out.
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.
METHANE CYLINDERS
The vehicle is provided with 4 cylinders
with a capacity of 95 litres; for the
Cargo Maxi version (long wheelbase), a
5
thcylinder is available as an optional,
increasing the capacity to 130 litres.The cylinders are all located under the
floor and protected by special guards.
The cylinders fig. 88, fig. 89 and fig.
90 are the tank that contains methane
in compressed gaseous state (200
rated bar at 15 °C).
Canister capacity:
- Short wheelbase versions: approx.
16.15 kg
- Short wheelbase versions: approx.
22.1 kg.
The amount of methane depends on
the outside temperature, the supply
pressure, the quality of the gas and the
type of refuelling system. Overall
cylinder volume approximately 95 litres
(short wheelbase versions) and 130
litres (long wheelbase versions).

WARNING
41)The Fiat Doblò Natural Power version is
equipped with a high pressure methane
system designed to run at a rated pressure
of 200 bar. It is dangerous to stretch the
system with higher pressures. To prevent
damage to the methane system parts
when towing or lifting the vehicle, follow
the instructions in the main handbook
in the chapter: "Towing the vehicle". 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 Qubo Natural
Power. The use of other components or
materials could cause malfunctions and
prejudice safety.
42)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.
43)If gas is smelt, switch from methane
operation to petrol operation and
immediately go to a Fiat Dealerships to
have the vehicle checked and possible
system faults supply excluded.
WARNING
8)Regardless of the last fuel system used,
at the following engine starting, after the
initial petrol stage, the system will
automatically switch to methane.
9)At the time of the switching request
there will be a metallic noise from the
valves which are pressurising the circuit
(more obvious with the ignition key in
the MAR-ON position). For the switching
logic described above, a delay between the
valve ticking and the switching off of the
instrument panel indication is completely
normal.
10)Do not switch between the two
operating modes whilst starting the engine.

MIN mark. In this case, wait for the engine to cool down, then
slowly and carefully open the cap, top up with coolant and
check that the level is between the MIN and MAX marks on
the reservoir itself. Also check visually for any fluid leaks. If,
when restarting, the warning light switches on again, contact a
Fiat Dealership.
If the vehicle is used under demanding conditions (e.g. in
high-performance driving): slow down and, if the warning light
stays on, stop the vehicle. Wait for 2 or 3 minutes with the
engine running and slightly accelerated to further favour the
coolant circulation. Then stop the engine. Check that the

amberINJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to MAR the
warning light switches on, but it should switch off as soon as the
engine is started.
The operation of the
warning light may be checked by the
traffic police using specific devices. Comply with the laws and
regulations of the country where you are driving.14)
If the warning light stays on or switches on when driving, it
means that the injection system is not working properly; in
particular, if the warning light comes on constantly, this indicates
a malfunction in the supply/ignition system that could cause
excessive exhaust emissions, a possible loss of performance,
poor driveability and high fuel consumption.
On some versions the display shows the dedicated message.
The warning light switches off if the malfunction disappears, but
is still stored by the system.Under these conditions, the vehicle can
continue travelling at moderate speed without
demanding excessive effort from the engine.
Prolonged use of the car with the warning light
on constantly may cause damage.
Contact a Fiat Dealership as soon as possible.
NOTE (for petrol engine only)
If the warning light flashes, it means that the catalytic converter
may be damaged.In this case, it is necessary to release the
accelerator pedal to lower the speed of the
engine until the warning light stops flashing.
Continue the journey at moderate speed, trying
to avoid driving conditions that may cause
further flashing and contact a Fiat Dealership as
