2015 Alfa Romeo Giulietta catalytic converter

VERY IMPORTANT
REFUELLING
Petrol engines: only refuel with unleaded petrol with octane rating (RON) not less than 95 in compliance with the European specification
EN228.Diesel engines: refuel only with diesel fuel conforming to the European specification EN590. The use of other products or mixtures
may damage the engine beyond repair and consequently invalidate the warranty, due to the damage caused.
STARTING THE ENGINE
Petrol engines: make sure that the handbrake is engaged; set the gear lever to neutral; fully depress the clutch pedal without pressing the
accelerator, then turn the ignition key to AVV and release it as soon as the engine has started.Diesel engines: turn the ignition key to
MAR-ON and wait for the
andwarning lights to switch off. Then turn the ignition key to AVV and release it as soon as the engine
has started.
PARKING ON FLAMMABLE MATERIAL
The catalytic converter develops high temperatures during operation. Do not park the car on grass, dry leaves, pine needles or other
flammable material: fire hazard.
RESPECTING THE ENVIRONMENT
The car is fitted with a system that carries out a continuous diagnosis of the emission-related components in order to help protect the
environment.
ELECTRICAL ACCESSORIES
If, after buying the car, you decide to add electrical accessories (with the risk of gradually draining the battery), contact an Alfa Romeo
Dealership. They will calculate the overall electrical requirement and check that the car’s electrical system can support the required load.
CODE Card (for versions/markets, where provided)
Keep it in a safe place, not in the car. Always carry the electronic code provided on the CODE card with you, in the case you need to perform
an emergency start.
SCHEDULED SERVICING
Correct maintenance of the car is essential for ensuring that it maintains its performance and its safety features, its environmental friendliness
and low running costs for a long time to come.
THE OWNER MANUAL CONTAINS…
…important information, advice and warnings for correct use, driving safety and maintenance of the car over time. Special attention must be
paid to the symbols provided (personal safety)(environmental protection) (car integrity).

60) Parking and other dangerous
manoeuvres are, however, always
the driver’s responsibility. While
carrying out these manoeuvres,
always make sure that no people
(especially children) or animals are
in the area concerned. The
parking sensors are an aid for the
driver, but the driver must never
allow their attention to lapse
during potentially dangerous
manoeuvres, even those executed
at low speeds.REFUELLING THE
CAR
Stop the engine before refuelling.
PETROL ENGINES
Only use unleaded petrol 95 R.O.N.
compliant with the European
specification EN228. The petrol octane
rating (R.O.N.) must not be lower than
95. In order to prevent damage to
the catalytic converter never introduce
even the smallest amount of leaded
petrol, even in the event of an
emergency.
DIESEL ENGINES
Use only diesel fuel compliant with
European specification EN590. The use
of other products or mixtures may
damage the engine beyond repair and
consequently invalidate the warranty,
due to the damage caused.
Operation at low
temperatures
If the outside temperature is very low,
the diesel thickens due to the formation
of paraffin clots with consequent
defective operation of the fuel supply
system.In order to avoid these problems,
different types of diesel are distributed
according to the season: summer type,
winter type and arctic type (cold,
mountain areas).
If refuelling with diesel whose
specifications are not suitable for the
usage temperature, it is advisable
to mix TUTELA DIESEL ART additive in
the proportions shown on the container
with the fuel. Pour the additive into
the tank before the fuel.
When using or parking the car for a
long time in the mountains or cold
areas, it is advisable to refuel using
locally available fuel. In this case, it is
also advisable to keep the tank over
50% full.
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.

GETTING TO KNOW YOUR CAR

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.
PROTECTING THE
ENVIRONMENT
The 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.94A0K0598
95A0K0599
81

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.

GETTING TO KNOW YOUR CAR

SPEEDOMETER (SPEED
INDICATOR)
This shows the speed of the car.
REV COUNTER
This indicates the engine rpm.
FUEL LEVEL GAUGE
This shows the amount of fuel left in the
fuel tank.
The warning light in the gauge lights up
when there are only 8 to 10 litres of
fuel remaining in the tank; if this
happens, refuel as soon as possible.
Do not travel with the fuel tank almost
empty: any gaps in fuel delivery could
damage the catalytic converter.ENGINE COOLANT
TEMPERATURE
INDICATOR
The needle shows the temperature of
the engine coolant and starts supplying
indications when the fluid temperature
exceeds approx. 50°C.
Under normal conditions, the needle
assumes different positions within
the scale depending on the usage
conditions.
The warning light turns on to indicate
an overheating of the engine coolant. In
this case, stop the engine and contact
an Alfa Romeo Dealership.TRIP COMPUTER
IN BRIEF
The Trip computer is used to display
information on car operation when
the key is turned to MAR.
This function is characterised by two
separate memories, called "Trip A"
and "Trip B", where the car's
"complete missions" (journeys) are
recorded in a reciprocally
independent manner.
Both memories can be reset: i.e. start
of a new journey.
“Trip A” is used to display the figures
relating to:
❒Range
❒Distance travelled
❒Average fuel consumption
❒Instant fuel consumption
❒Average speed
❒Trip time (driving time).
“Trip B” may be used to display the
figures relating to:
❒Distance travelled B
❒Average consumption B

KNOWING THE INSTRUMENT PANEL

Warning lights on
panelWhat it means What to do
amberINJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to
MAR-ON the warning light switches on, but it should
switch off as soon as the engine is started. The operation
of
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.
13)
If the warning light remains on or switches on whilst
driving, it means that the injection system is not working
properly. The warning light on constantly signals a
malfunction in the supply/ignition system which could
cause high exhaust emissions, a possible loss of
performance, poor driveability and high consumption.
On some versions, the display shows the dedicated
message. The warning light goes out after the fault
disappears: the indication is stored in the system.Under these conditions, you may continue
travelling at a moderate speed without
demanding excessive effort from the
engine. Prolonged use of the car with the
warning light on constantly may cause
damage.
Contact an Alfa Romeo Dealership as
soon as possible.
Petrol engines only
If the warning light flashes, it means that the catalytic
converter may be damaged.In this case, 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 an Alfa Romeo
Dealership as soon as possible.

Proceed as follows:
19)
❒engage the handbrake and place the
gear lever in neutral;
❒turn the ignition key to MAR-ON: the
warning lights
andon the
instrument panel will turn on (for
versions/markets, where provided);
❒wait for the warning lights to switch
off;
❒fully depress the clutch pedal,
without touching the accelerator;
❒turn the ignition key to AVV as soon
as warning light
switches off.
Waiting too long will waste the
heating work carried out by the glow
plugs. Release the key as soon as
the engine starts.
WARMING UP THE
ENGINE JUST AFTER IT
HAS STARTED
Proceed as follows:
❒drive off slowly, letting the engine turn
at medium speed without
accelerating abruptly;❒do not demand full performance at
first. It is advisable to wait until the
engine coolant temperature indicator
starts moving.
STOPPING THE ENGINE
Turn the ignition key to STOP while the
engine is idling.
IMPORTANT After a demanding drive,
before turning the engine off you should
let it idle so that the temperature in the
engine compartment decreases.
WARNING
100) It is dangerous to run the
engine in enclosed areas. The
engine takes in oxygen and
releases carbon dioxide, carbon
monoxide and other toxic gases.
101) The brake servo is not active
until the engine is started, so
you would need to apply much
more force than usual to the
brake pedal.
102) Do not start the engine by
pushing, towing or driving
downhill. These manoeuvres may
damage the catalytic converter.
