IGNITION SWITCH
Operation
The key can be turned to three different
positions fig. 9:
STOP: engine off, key can be
removed, steering column locked.
Some electrical devices (e.g. radio,
central door locking system, alarm, etc.)
are still available;
MAR-ON: driving position. All
electrical devices are available;
AVV: engine starting.
The ignition switch is fitted with a safety
system that requires the ignition key to
be turned back to STOP if the engine
does not start, before the starting
operation can be repeated.
...... 03)
STEERING LOCK
Activation
When the key is at STOP, remove the
key and turn the steering wheel until it
locks.
Deactivation
Move the steering wheel slightly and
turn the ignition key to MAR-ON.
4) 5)
WARNING
2)If the ignition device has been tampered
with (e.g. an attempted theft), have it
checked over by the Alfa Romeo
Dealership before driving again.
3)Always take the key with you when you
leave your vehicle to prevent someone
from accidentally operating the controls.
Remember to engage the electric parking
brake. Never leave children unattended in
the vehicle.
4)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 adversely affect performance,
invalidate the warranty, cause serious
safety problems and also result in the car
not meeting type-approval requirements.
5)Never extract the mechanical key while
the vehicle is moving. The steering wheel
will automatically lock as soon as it is
turned. This holds true for cars being
towed as well.
SEATS
ADJUSTMENTS
Lengthwise adjustment
(for versions/markets, where provided)
Lift lever A fig. 10 and push the seat
forwards or backwards: in the driving
position your arms should rest on the
rim of the steering wheel.
6) 7)
Alfa Romeo’s advice: the seat must be
adjusted so that the entire sole of the
foot presses on the brake pedal when it
is fully depressed; at the same time,
your right leg must be bent slightly. In
this way, in the event of emergency, the
driver can generate sufficient force to
achieve adequate pressure on the
brake pedal. Moreover, this reduces the
risk of leg injuries in the event of an
accident.

STEERING WHEEL
Adjustment
It can be adjusted axially and vertically.
To adjust, release lever A fig. 12,
pushing it forwards (position 1). Having
made the adjustment, lock lever A by
pulling it towards the steering wheel
(position 2).
9) 10)
Alfa Romeo’s advice: after lengthwise
seat adjustment and backrest angle
adjustment, the steering wheel can be
adjusted. To check that the steeringwheel position is correct, the left arm
must be extended completely, so that it
touches (without gripping) the highest
part of the steering wheel rim with the
wrist. At the same time, the driver’s
shoulders must remain firmly in contact
with the backrest. In this position, when
you grip the rim of the steering wheel in
"9:15" position (i.e. with hands
corresponding to the hands of a clock
at 9 hours and 15 minutes, imagining
that the wheel is a clock face) there
should be an angle of 90 degrees
between upper arm and forearm. This
permits maximum control of the
steering wheel and ensures that it is
used as a precision instrument and not
as a handgrip on bends. This is also the
most ergonomically correct driving
position, thus permitting minimum
fatigue when driving.
WARNING
9)All adjustments must be carried out only
with the car stationary and engine off.
10)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 adversely affect
performance and safety, invalidate the
warranty and also result in the car not
meeting type-approval requirements.

HEADLIGHTS
LIGHT BEAM DIRECTION
The correct orientation of the headlights
is important for the driver's comfort and
safety as well as for all other road users.
This is also covered by a specific rule of
the highway code.
The headlights must be correctly
directed to ensure the best visibility
conditions for all drivers. Contact a
dedicated Alfa Romeo Dealership to
have the headlights checked and
adjusted.
ADJUSTING THE
HEADLIGHTS ABROAD
The dipped beam headlights are
aligned to comply with the regulations
of the country of purchase. When in
countries where you drive on the other
side of the road, you need to alter the
beam direction in order not to dazzle
the vehicles travelling in the opposite
direction, proceeding as follows:
39
IMPORTANT Maintain a tight grip on

safety in low-grip driving conditions. It is
advisable to select "All Weather" mode
in the presence of low-grip road
surfaces.
"ELECTRONIC Q2" SYSTEM: the
system is deactivated.
Engine and gearbox/transmission:
standard response.
Deactivation
To deactivate “All Weather” mode and
return to “Natural”, move lever A
fig. 47 upwards (to letter “d”) and keep
it in this position for half a second.
IMPORTANT
During the first 250 km of usage of
the car, the Dynamic and Race modes
are inhibited. Within this first interval of
start-up mileage it is advisable to refrain
from an aggressive driving style, so that
the best gear shifting quality can be
achieved over time.
When the engine is next started, the
"All Weather" or "Dynamic" mode
selected previously is retained. The
system will reactivate in "All Weather" or
"Dynamic" mode, depending on which
mode was selected before the engine
was switched off.
When the engine is next started, the
"Race" mode selected previously is not
retained. The system will reactivate in
"Dynamic" mode.
It is not possible to go directly from
“Dynamic” mode to “All Weather” modeand vice versa. You must always first go
back to “Natural” mode and then select
the other mode.
System failure
In the event of system failure or a fault
with lever A fig. 47, no driving modes
can be selected.
The display will become grey (same
screen as "Natural" mode) but without
an indication of the Alfa DNA setting.
The display will also show a warning
message.
EOBD SYSTEM
(European On
Board Diagnosis)
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 efficiency of the system;
indicate an increase in emissions;
indicate the need to replace
deteriorated 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
dedicated Alfa Romeo Dealership is

54)The tyre repair kit (Fix&Go) provided
with the car (for versions/markets, where
provided) is compatible with the TPMS
sensors; using sealants not equivalent with
that in the original kit may adversely affect
its operation. If sealants not equivalent with
the original one are used, it is
recommended to have the TPMS sensors
checked by a qualified repair centre.REFUELLING THE
CAR
The car features the "Fast Fuel" system,
which prevents refuelling with incorrect
fuels (e.g. diesel for a petrol engine).
Stop the engine before refuelling.
Only refuel with unleaded petrol with
octane rating (RON) not less than 95, in
compliance with the European
specification EN228. In particular, the
4C’s engine has been designed to
comply with all emission limits while
simultaneously guaranteeing minimal
consumption and maximum
performance, using premium-quality
unleaded petrol with octane rating
(RON) of 98 or higher.
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.
IMPORTANT An inefficient catalytic
converter leads to harmful exhaust
emissions, thus contributing to air
pollution.
IMPORTANT Never introduce leaded
petrol to the tank, even in small
amounts in an emergency, as this
would damage the catalytic converter
beyond repair.
FILLING THE TANK
To ensure that you fill the tank
completely, top up twice after the first
click of the fuel supply gun. Avoid
further top-ups, which could cause
faults in the fuel supply system.
REFUELLING
PROCEDURE
The car features a "Fast Fuel" device,
integrated with the opening for the fuel
tank: it opens and recloses
automatically when the fuel supply gun
is inserted/removed.
The "Fast Fuel" device is provided with
an inhibitor which prevents refuelling
with incorrect fuel.
The refuelling procedure described
below is illustrated on the label
fig. 56 located inside the fuel flap. The
label also indicates the fuel type
(UNLEADED FUEL=petrol).
