2016 FIAT DUCATO lights

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.

SAVING FUEL
GENERAL INFORMATION
The general factors that affect fuel
consumption are listed below.
Vehicle maintenance
Tyres
Unnecessary loads
Roof rack/ski rack
Electric devices
Climate control system
Devices for aerodynamic control
DRIVING STYLE
The main driving styles that affect fuel
consumption are listed below.
Starting
Do not warm up the engine at low or
high revs when the vehicle is stationary;
this causes the engine to warm up
more slowly, thereby increasing fuel
consumption and emissions.
Unnecessary actions
Avoid accelerating when stopped at
traffic lights or before switching off the
engine.Gear selection
In the same way improper use of a high
gear increases consumption, emissions
and engine wear.
Top speed
Fuel consumption increases
considerably with speed.
Acceleration
Accelerating violently will greatly affect
consumption and emissions:
acceleration should be gradual.
CONDITIONS OF USE
The main usage conditions that
negatively affect fuel consumption are
listed below.
Cold starting
Short journeys and frequent cold starts
do not allow the engine to reach
optimum operating temperature.
Traffic and road conditions
Rather high consumption levels are
linked to situations with heavy traffic, for
instance when travelling in queues
with frequent use of the lower gears or
in cities with many traffic lights. Winding
mountain roads and rough road
surfaces also adversely affect
consumption.Stops in traffic
During prolonged hold-ups (e.g. level
crossings) the engine should be
switched off.

STARTING AND DRIVING

REPLACING A BULB
GENERAL
INSTRUCTIONS
139) 140)
46)
When a light is not working, check
that the corresponding fuse is intact
before changing a bulb. For the location
of fuses, refer to the paragraph
"Replacing fuses" in this chapter.
before changing a bulb check the
contacts for oxidation;
burnt bulbs must be replaced by
others of the same type and power;
always check the headlight beam
direction after changing a bulb;
IMPORTANT A slight misting may
appear on the internal surface of the
headlight: this does not indicate a fault
and is caused by low temperature
and the degree of humidity in the air.
Misting will rapidly disappear when the
headlights are switched on. The
presence of drops inside the headlights
indicates infiltration of water. Contact
a Fiat Dealership.
WARNING
139)Modifications or repairs to the
electric system that are not carried out
properly or do not take the system
technical specifications into account can
cause malfunctions leading to the risk
of fire.
140)Halogen bulbs contain pressurised
gas, in the case of breakage they may
burst causing glass fragments to be
projected outwards.
WARNING
46)Halogen bulbs must be handled
holding the metallic part only. Touching the
transparent part of the bulb with your
fingers may reduce the intensity of the
emitted light and even reduce the lifespan
of the bulb. In the event of accidental
contact, wipe the bulb with a cloth
moistened with alcohol and let the bulb
dry.
