2016 Alfa Romeo 4C instrument panel

WARNING LIGHTS AND MESSAGES
WARNING The warning light switches on together with a dedicated message and/or acoustic signal when applicable. These
indications are indicative and precautionary and as such must not be considered as exhaustive and/or alternative to the
information contained in the Owner Handbook, which you are advised to read carefully in all cases. Always refer to the
information in this section in the event of a failure indication.
IMPORTANT Failure indications displayed are divided into two categories: very serious and less serious failures. Serious faults
are indicated by a repeated and prolonged warning "cycle". Less serious faults are indicated by warning "cycle" with a shorter
duration. The display cycle of both categories can be interrupted. The instrument panel warning light will stay on until the cause
of the malfunction is eliminated.

the warning light switches on, but should switch off as soon as
the engine is started.
The operation of the
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.
If the warning light stays on or switches on when driving, it means
that the injection system is not working properly; in particular, if
the warning light comes on constantly, this indicates a
malfunction in the supply/ignition system that could cause
excessive exhaust emissions, a possible loss of performance,
poor driveability and high fuel consumption.
On some versions, the display shows the dedicated
message.
The warning light switches off if the malfunction
disappears, but it is still stored by 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 the dedicated Alfa Romeo Dealership
as soon as possible.

may be damaged.In this case, it is necessary to release the
accelerator pedal to lower the speed of the
engine until the warning light stops flashing.

to avoid driving conditions that may cause
further flashing and contact the dedicated Alfa
