FAILED ENGINE CUT-OUT CONDITIONS
When 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;
❍very cold outside temperature;
❍battery not sufficiently charged;
❍heated rear windscreen on;
❍windscreen wipers working at maximum speed;
❍particulate filter regeneration 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
system (for versions/markets, where provided), if an adequate
level of thermal comfort has not been reached or MAX-DEF func-
tion activation;
❍during the first period of use, to initialize the system;
In these cases, a message is shown on the display and the sym-
bol
Uwill blink (the latter for versions/markets, where provid-
ed).
If climate comfort is to be favoured, the
Start&Stop system can be disabled, for a contin-
uous operation of the climate control system.

Notes
If the clutch is not pressed, after 3 minutes from the engine stop-
ping, 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
RESTARTING CONDITIONS
For reasons of comfort, limiting harmful emissions and safety pur-
poses, the power unit can restart automatically without any action
on behalf of the driver if certain conditions are met, including:
❍battery not sufficiently charged;
❍windscreen wipers working at maximum speed;
❍low braking system vacuum, e.g. following the brake pedal be-
ing pressed repeatedly;
❍car in motion, for example when driving on hilly roads;
❍stopping the engine using Start&Stop longer than approxi-
mately 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 func-
tion activation;
With gear engaged, the automatic engine restarting is possible on-
ly by fully pressing the clutch pedal. This operation is indicated to
the driver by means of a message on the display and by symbol
Ublinking (the latter for versions/markets, where provided).

SAFETY FUNCTIONS
When the engine is stopped by the Start&Stop system, if the dri-
ver releases his/her seat belt and opens the driver’s or passenger’s
door, the engine can be restarted only using the ignition key.
This condition is indicated to the driver by means of a buzzer and
by the symbol
Ublinking on the display (with a message, for
versions/markets, where provided).
ENERGY SAVING FUNCTION
(for versions/markets, where provided)
If, as a result of the engine automatic restarting, the driver does not
carry out any action on the vehicle for over 3 minutes, the Start&Stop
system stops the engine once and for all, to prevent fuel consump-
tion. In these cases, the engine can be restarted only using the ig-
nition key.
NOTEIn any case, it is possible to keep the engine running by de-
activating the Start&Stop system.
IRREGULAR OPERATION
In the event of malfunction, the Start&Stop system is deactivated.
The driver is informed of the fault by the flashing
Usymbol (ver-
sions with multifunction display) or
jsymbol (versions with re-
configurable multifunction display). For versions/markets, where
provided, a message is also displayed. In this case, contact
Alfa Romeo Authorized Services.
STORING THE CAR
In the case of storage, special care must be taken to disconnect the
battery electrical power supply.
Proceed as follows: detach the connector A-fig. 83 (by pressing but-
ton B) from sensor C for monitoring the status of the battery in-
stalled on the battery negative pole D. This sensor should never
be disconnected from the pole except if the battery is replaced.
fig. 83A0K0179m
In case of battery replacement, always contact
Alfa Romeo Authorized Services. Replace the bat-
tery using a new one of the same type (HEAVY
DUTY) and having the same specifications.

EMERGENCY STARTING
When jump starting, never connect the negative lead (–) of the
auxiliary battery to the negative pole A-fig. 84 of the car battery,
but rather to an engine/gearbox earth point.
Before opening the engine hood, make sure that
the engine is off and that the ignition key is in STOP
position. Follow the instructions on the plate af-
fixed on the front crossmember (fig. 85). You are advised
to extract the key when other people are inside the car.
Remove the ignition key or turn it to the STOP position be-
fore leaving the car. During refuelling, make sure that the
engine is off and the key is in STOP position.

EOBD SYSTEM
(European On Board Diagnosis)
(for versions/markets, where provided)
The aim of the EOBD (European On Board Diagnosis) system is to:
❍to monitor system efficiency;
❍indicate an increase in emissions;
❍to warn of the need to replace deteriorated 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 com-
pletely, Alfa Romeo Authorized Services are obliged to run tests
and, if necessary, road tests which may also call for a long journey.
DUAL PINION ACTIVE STEERING
This only operates with the key turned to MAR and the engine start-
ed. The steering allows the force required at the steering wheel
to be adjusted to suit driving conditions. The different power as-
sistance modes can be selected via the d,n,a positions of the"Alfa
DNA System" lever (see paragraph entitled "Alfa DNA System").
IMPORTANT The steering system will need to be initialised after
disconnecting the battery. A warning light will come on to indicate
this. Simply turn the steering wheel all the way from one end to the
other or simply drive in a straight line for a few hundred metres.
Under no circumstances should aftermarket op-
erations be carried out involving steering system
or steering column modifications (e.g. installation
of anti-theft device). This could negatively affect perfor-
mance and safety, invalidate the warranty, cause serious
safety problems and also result in non-compliance of the
car with type-approval requirements.

INSTALLING ELECTRICAL/
ELECTRONIC DEVICES
Electric and electronic devices installed after buying the car in the
context of after-sales service must carry the following label:
e CE.
Fiat Group Automobiles S.p.A. authorises the installation of trans-
ceiving devices provided that they are installed by a specialised cen-
tre according to rules of good engineering practice in compliance
with the manufacturer’s instructions.
IMPORTANT Traffic police may not allow the car on the road if de-
vices have been fitted which modify the features of the car. This
may also invalidate the warranty if faults occur that are either di-
rectly or indirectly related to the installation of these devices.
Fiat Group Automobiles S.p.A. shall not be liable for damage caused
by the installation of accessories either not supplied or recommend-
ed by Fiat Group Automobiles S.p.A. and/or not installed in com-
pliance with the provided instructions.

REFUELLING THE CAR
Switch off the engine before refuelling.
PETROL ENGINES
Only use unleaded petrol. The petrol octane rating (RON) must not
be lower than 95.
In order to prevent damage to the catalytic converter never intro-
duce even the smallest amount of leaded petrol, even in the event
of an emergency.
DIESEL ENGINES
Only use 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, depend-
ing on 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 dis-
tributed 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 ad-
visable to mix TUTELA DIESEL ART additive with the fuel, in the pro-
portions shown on the container. Pour the additive into the tank
before the fuel.
When parking or storing 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.

The catalytic converter and particulate filter (DPF)
reach very high temperatures during operation.
Do not park the vehicle on grass, dry leaves, pine
needles or other flammable material: fire hazard.
PROTECTING THE ENVIRONMENT
The devices for reducing petrol engine emissions are the following:
catalytic converter, lambda sensors and anti-evaporation system.
The following devices are used for reducing diesel fuel engine emis-
sions: oxidising catalytic converter, exhaust gas recirculation (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 al-
most completely eliminates carbon particle emissions.
