2015 Alfa Romeo 4C warning light

ESSENTIAL INFORMATION!
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. The use of petrol that does not
conform to the specification indicated may cause the
warning light to switch on and the irregular operation of the engine.
STARTING THE ENGINE
Make sure that the handbrake is engaged. Press the brake pedal and, without pressing the accelerator, turn the ignition key to AVV; 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 purchasing the car, you want to install accessories that require an electrical supply (with the risk of gradually draining the battery),
contact the dedicated Alfa Romeo Dealership which will calculate the overall electrical consumption and check that the car’s electrical system
can support the required load.
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 HANDBOOK CONTAINS…
... important information, advice and warnings for correct use, driving safety and maintenance of your car over time. Special attention must

GRAPHICAL INDEX

SYMBOLS
Some car components have coloured
labels whose symbols indicate
precautions to be observed when using
this component. Under the engine
cover there is also a label that
summarises all the symbols.
ALFA ROMEO CODE
SYSTEM
IN BRIEF
This is an electronic engine locking
system which increases protection
against attempted thefts of the car. It
is automatically activated when the
ignition key is removed.
There is an electronic device in each
key which can identify the signal
emitted, when the engine is started,
from an aerial built into the ignition
switch. The signal, which changes
each time the engine is started, is the
“password” by means of which the
control unit recognises the key and
enables starting.
1)
Operation
Each time the car is started by turning
the ignition key to MAR-ON, the Alfa
Romeo CODE system control unit
sends an acknowledgement code to
the engine management control unit to
deactivate the inhibitor.
The code is sent only if the Alfa Romeo
CODE system control unit has
recognised the code transmitted by the
key.Each time the ignition key is turned to
STOP, the Alfa Romeo CODE system
deactivates the functions of the engine
management control unit.
Irregular operation
If, during starting, the code is not
correctly recognised, the
digital
warning light switches on in the display.
In this case, turn the key to STOP and
then to MAR-ON; if it is still locked,
try again with the other keys that come
with the vehicle. If it is still not possible
to start the engine, contact the
dedicated Alfa Romeo Dealership.
Activation of warning
light while driving
❒If the
digital warning light on the
display switches on, this means that
the system is running a self-diagnosis
(for example due to a voltage drop).
❒If the
digital warning light remains
on, contact the dedicated Alfa
Romeo Dealership.

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 dedicated Alfa Romeo
Dealership before driving again.
3) Always remove the key when you
leave your car to prevent someone
from accidentally operating the
controls. Remember to engage
the handbrake. Never leave
children unattended in the car.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 and safety,
invalidate the warranty and also
result in non-compliance of the
car with type-approval
requirements.
5) Never extract the key while the
car is moving. The steering wheel
would automatically lock as soon
as it is turned. This also applies
to cases in which the car is towed.
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.

.
It is advisable to switch the internal air
recirculation on while standing in
queues or in tunnels to prevent the
introduction of polluted air.
Do not use the function for a long time,
particularly if there are two people on
board, to prevent the windows from
misting.
IMPORTANT The internal air
recirculation system makes it possible
to reach the required heating or
ventilation conditions more quickly. Do
not use the internal air recirculation
function on rainy/cold days to avoid the
possibility of the windows misting.
CLIMATE CONTROL
(cooling)
Proceed as follows:
❒turn knob A to the blue section;
❒turn knob C to 1 (1st fan speed). For
rapid cooling, turn knob C to 4
(maximum fan speed).

SYSTEM MAINTENANCE
In winter, the climate control system
must be turned on at least once a
month for about 10 minutes. Have the
system inspected at a dedicated Alfa
Romeo Dealership before the summer.
3)
IMPORTANT
3) The system uses R-1234yf
coolant which does not pollute the
environment in the event of
accidental leakage. Under no
circumstances should you use
R-134a fluid which, in addition to
being incompatible with the
system’s components, contributes
greatly to the greenhouse effect.
