light Alfa Romeo Giulietta 2014 Service Manual

EOBD SYSTEM
(European On
Board Diagnosis)(for versions/markets, where provided)
Operation
The EOBD system (European On Board
Diagnosis) carries out a continuous
diagnosis of the components of the car
related to emissions.
It also alerts the driver, by switching on
the
warning light on the instrument
panel, together with a message on
the display, when these components
are no longer in peak condition (see
“Warning lights and messages”
paragraph in the "Knowing the
instrument panel" chapter).
The aim of the EOBD system (European
On Board Diagnosis) is to:
❒monitor the system efficiency;
❒indicate an increase in emissions;
❒indicate the need to replace
damaged components.The car also has a connector, which
can interface with appropriate tools,
that makes it possible to read the error
codes stored in the electronic control
units together with a series of specific
parameters for engine operation and
diagnosis. This check can also be
carried out by the traffic control
authorities.
IMPORTANT After eliminating a fault, to
check the system completely, the Alfa
Romeo Dealership is obliged to run
tests and, if necessary, road tests
which may also require a long journey.
DUAL PINION
ACTIVE STEERINGOperation
This only operates with the key turned
to MAR-ON and the engine started.
The steering allows the force required
at the steering wheel to be adjusted
to suit driving conditions. The different
power assistance modes can be
selected via the d, n, a positions of the
“Alfa DNA System” lever (see paragraph
entitled “Alfa DNA System”).
56)
IMPORTANT After the battery is
disconnected, the steering must be
initialised. The warning light switches on
to indicate this. To carry out this
procedure, simply turn the steering
wheel all the way from one end to the
other or drive in a straight line for about
a hundred metres.

FILLING THE TANK
To 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
The fuel flap is unlocked when the
central locking system is released and
automatically locked when the central
locking system is applied.
Opening
Press flap A fig. 94 to release it and
access fuel tank cap B. Then press cap
B and turn it anticlockwise.
61)
The cap is provided with a loss
prevention device C which attaches it
to the flap and prevents it from being
lost. Attach the cap to device D during
refuelling.Emergency flap opening
In case of emergency, pull the cord A
fig. 95 on the right-hand side of the
boot to open the fuel flap.
Pulling the cord will unlock the flap: it
will then be necessary to press on
the flap to open it.
Closure
Release cap B from device D and insert
it in its housing. Then tighten the cap
clockwise until one or more clicks
are heard. Finally, close flap A checking
that it is correctly locked.
The sealing may cause a slight pressure
increase in the tank. A little breathing
off, while slackening the cap is
absolutely normal.
WARNING
61) Keep naked flames or lit
cigarettes away from the fuel tank
filler: fire risk. Avoid bringing
your face close to the filler, in
order not to breathe in harmful
vapours.

GETTING TO KNOW YOUR CAR

PROTECTING THE
ENVIRONMENTThe following devices are used for
reducing petrol fuel engine emissions:
catalytic converter, oxygen sensors and
evaporation control system
The following devices are used for
reducing diesel fuel engine emissions:
oxidising catalytic converter, exhaust
gas recirculation system (EGR) and
particulate filter (DPF).
62)
DIESEL PARTICULATE
FILTER (DPF)
(Diesel Particulate Filter)
(for versions/markets, where provided)
The Diesel Particulate Filter is a
mechanical filter, integral to the exhaust
system, that physically traps carbon
particles present in the exhaust gases
of diesel engines.
The diesel particulate filter is needed to
eliminate almost all carbon particle
emissions in compliance with
current/future regulations and
standards.During standard use of the vehicle, the
engine control unit records a set of data
(e.g.: travel time, type of route,
temperatures, etc.) and it will then
calculate how much particulate has
been trapped by the filter.
Since this filter physically traps
particulate, it should be periodically
regenerated (cleaned) at regular
intervals by burning carbon particles.
The regeneration procedure is
controlled automatically by the engine
management control unit according
to the filter conditions and vehicle use
conditions.
During the regeneration there may be a
limited increase in the engine idle
speed, fan activation, a limited increase
in fumes and high temperatures at the
exhaust.
These are not faults; they do not impair
normal car performance or damage
the environment. If the dedicated
message is displayed, see contents of
"Warning lights and messages"
paragraph, in chapter "Knowing the
instrument panel".
WARNING
62) The catalytic converter and
particulate filter (DPF) reach very
high temperatures during
operation. Therefore do not park
the car on flammable materials
(e.g. grass, dry leaves, pine
needles, etc.): fire hazard.

KNOWING THE INSTRUMENT PANEL

GEAR SHIFT INDICATOR
The “GSI” (Gear Shift Indicator) system
advises the driver to change gear
through a special indication on the
display fig. 99.
Through the GSI, the driver is notified
that changing gear will allow a
reduction in fuel consumption.
Therefore, for driving oriented towards
reducing fuel consumption, it is
recommended to stick to "Natural" or
"All Weather" mode and to follow the
suggestions of the Gear Shift Indicator,
where the traffic conditions allow it.
When the SHIFT UP icon (
SHIFT) is
shown on the display, the GSI is
advising the driver to engage a higher
gear, when the SHIFT DOWN (
SHIFT) icon is displayed, it advises
the driver to engage a lower gear.NoteThe indication in the instrument
panel remains on until the driver shifts
gear or the driving conditions go back
to a situation where gearshifting is
not required to improve consumption.
WELCOME MOVEMENT
On some versions, when the key is
turned to MAR-ON, the following
occurs:
❒quick movement (up and down) of
the speedometer and rpm gauge;
❒lighting of graphic symbols/display;
❒displaying of an animated graphic
representation of the vehicle profile.
Gauge movement
❒If the key is removed from the ignition
switch whilst the gauges are moving,
they immediately go back to their
initial position.
❒Once they have reached the full scale
values, the gauges rest on the value
indicated by the vehicle.
❒The movement of the gauges stops
when the engine is started.Lighting of graphic
symbols/display
A few seconds after the key is inserted,
the gauges, graphic symbols and
display light up in sequence.
Display of graphic
animation
When the key is removed from the
ignition switch (with the doors closed),
the display remains lit up and shows
a graphic animation.
The display lighting is then dimmed
gradually until it goes out completely.
