2013 Alfa Romeo Giulietta engine

START&STOP SYSTEM(for versions/markets, where provided)
The Start&Stop system automatically stops the engine each time the car
is stationary and starts it again when the driver wants to move off.
In this way, the efficiency of the car is increased, by reducing
consumption, emissions of harmful gases and noise pollution.OPERATING MODESEngine stopping mode
With the car stopped, the engine stops with gearbox in neutral and
clutch pedal released.
NoteThe engine can only be stopped automatically over about 10
km/h, to prevent the engine from being repeatedly stopped when
driving at walking pace.

ENGINE STOPPING FAILURE
CONDITIONSWhen the system is operating, due to comfort, emission control and
safety reasons, the engine does not stop in some conditions, among
which:
❒engine still cold;
❒especially cold outside temperature;
❒battery not sufficiently charged;
❒particulate filter regeneration (DPF) in progress (diesel engines only);
❒driver's door not shut;
❒driver's seat belt not fastened;
❒reverse gear engaged (for example, for parking manoeuvres);
❒for versions equipped with dual zone automatic climate control (for
versions/markets, where provided), if an adequate level of thermal
comfort has not been reached or with MAX-DEF function activation;
❒during the first period of use, to initialise the system.
If the climate comfort is to be favoured, the Start&Stop
system can be deactivated, for a continuous operation of
the climate control system.
ENGINE RESTARTING CONDITIONSDue to comfort, emission control and safety reasons, the engine can
restart automatically without any action by the driver, under special
conditions, such as:
❒battery not sufficiently charged;
❒reduced braking system vacuum (e.g. if the brake pedal is pressed
repeatedly);
❒car moving (e.g. when driving on roads with a gradient);
❒engine stopping by Start&Stop system for over 3 minutes;
❒for versions equipped with dual zone automatic climate control
system (for versions/markets, where provided), if an adequate level
of thermal comfort has not been reached or MAX-DEF function
activation.
With gear engaged, automatic engine restarting is possible only by
fully depressing the clutch pedal. The driver is informed by the
displaying of a message on the display and - for versions/markets,
where provided - by the flashing of the symbol
.
Notes
If the clutch is not pressed, about 3 minutes after the engine stops, the
engine can be restarted only using the ignition key.
In cases when the engine stops and this is not desired, due for example
to the clutch pedal being released sharply with a gear engaged, if the
Start&Stop system is activated, the engine can be restarted by fully
depressing the clutch pedal or by placing the gear lever in neutral.

SAFETY FUNCTIONSWhen the engine is stopped by the Start&Stop system, if the driver
releases his/her seat belt and opens the driver's or passenger's door,
the engine can be restarted only using the ignition key.
The driver is informed by a buzzer and by the flashing of the symbol
on the display; on some versions, a message is displayed as well.
"ENERGY SAVING" FUNCTION(for versions/markets, where provided)
If, following automatic engine restarting, the driver does not carry out
any action on the car for over 3 minutes, the Start&Stop system stops
the engine once and for all, to prevent fuel consumption. In these
cases, the engine can be restarted only using the ignition key.
NOTE In any case, it is possible to keep the engine running by
deactivating the Start&Stop system.IRREGULAR OPERATIONIn the event of malfunction, the Start&Stop system is deactivated.
The driver is informed of the fault by the flashing
symbol (versions
with multifunction display) or
symbol (versions with reconfigurable
multifunction display). For versions/markets where provided, a
message is also displayed.
In this case, contact Alfa Romeo Authorized Services.
CAR INACTIVITYIn the event of car inactivity (or if the battery is replaced), special
attention must be paid to the disconnection of the battery power
supply.
Proceed as follows: detach the connector A fig. 90 (by pressing button
B) from sensor C for monitoring the status of the battery installed on
the negative battery pole D. This sensor should never be disconnected
from the pole except if the battery is replaced.
In case of battery replacement, always contact Alfa
Romeo Authorized Services. Replace the battery with
one of the same type (HEAVY DUTY) and with the same
specifications.
IMPORTANT After turning the ignition key to STOP, wait at least 1
minute before disconnecting the electrical supply to the battery.

JUMP STARTINGWhen jump starting, never connect the negative lead (–) of the
auxiliary battery to the negative pole A fig. 91 of the car battery, but
rather to an engine/gearbox earth point.
Before opening the bonnet, make sure the engine is off and
the ignition key is in the STOP position. Follow the
instructions on the label on the front crossmember (fig. 92).
It is advisable to extract the key when there are other people in the
vehicle. Exit from the car only after having removed the ignition key or
having rotated it to the STOP position. During refuelling, make sure
that the engine is off and that the ignition key is in the STOP position.
EOBD SYSTEM (European On
Board Diagnosis)(for versions/markets, where provided)
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 diagnostic connector that can be interfaced with
appropriate tools, which 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 police.
IMPORTANT After eliminating a fault, to check the system completely,
Alfa Romeo Authorised Services are obliged to run tests and, if
necessary, road tests which may also call for a long journey.

DUAL PINION ACTIVE STEERINGThis only operates with the key turned to MAR 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”).
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.
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, invalidate the
warranty and also result in non-compliance of the car with
type-approval requirements.
WIRING FOR RADIO SYSTEM(for versions/markets, where provided)
If no car radio was requested at the time of purchase, the car is
provided with a compartment fig. 93 on the dashboard.
The radio setup system is composed of:
❒car radio power supply cables, front and rear speakers and an
aerial;
❒radio housing;
❒aerial on car roof.
The car radio must be fitted in the special compartment A fig. 93,
which can be accessed by pressing the two retaining tabs B in the
compartment itself; power supply cables are located in this area.
When connecting a car radio to the radio wiring
contact Alfa Romeo Authorized Services to prevent any
faults from occurring that might compromise the safety
of the car.

REFUELLING THE CARStop the engine before refuelling.PETROL ENGINESOnly use unleaded petrol. The petrol octane rating (RON) 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 ENGINESUse 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 fuel are
distributed according to the season: summer type, winter type and
arctic type (cold/mountain areas). If refuelling with diesel fuel whose
features are not suitable for the temperature of use, it is advisable
to mix TUTELA DIESEL ART additive with the fuel, in the proportions
shown on the container. Pour the additive into the tank before the fuel.
When using or parking the vehicle 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.
FUEL TANK CAPThe 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. 98 to release it and access the fuel tank cap B. Then
press cap B and turn it anticlockwise.
The plug is provided with a loss prevention device C which secures it to
the flap, so it cannot be lost. Attach the cap to device D during
refuelling.

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).
DIESEL PARTICULATE FILTER (DPF)(for versions/markets, where provided)
This is a mechanical filter, fitted in the exhaust system, which almost
completely eliminates carbon particle emissions.
The catalytic converter and particulate filter (DPF) reach
very high temperatures during operation. Therefore
do not park the car on flammable materials (grass, dry
leaves, pine needles etc.): fire hazard.

Front seats (warning light
no. 1 = driver and
no. 5 = passenger)Driver
If the driver is the only occupant and their seat belt is not fastened,
when 20 km/h is exceeded or when travelling at a speed between 10
and 20 km/h for longer than 5 seconds, an acoustic signal cycle
will be started for the front seats (continuous acoustic signal for
6 seconds followed by a 90 second beep). The warning light will flash.
The warning lights will stay on constantly at the end of the cycle until
the engine is stopped. The acoustic signal will be interrupted
immediately when the driver’s seat belt is fastened and the warning
light will turn green.
The reminder cycle (acoustic and visual) will be repeated as described
above and the red warning light will flash if the seat belt is unfastened
again while travelling.
Passenger
A similar situation applies to the front passenger, with the difference
that the warning light turns green and the indication is also interrupted
when the passenger leaves the car.
If both front seat belts are unfastened a few seconds apart while the
car is travelling, the acoustic signal will refer to the most recent event
and the two warning lights will proceed with the visual indication
independently.
