amberINJECTION/EOBD SYSTEM FAILURE
In normal conditions, when the ignition key is turned to MAR-ON
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.
If the warning light flashes, it means that the catalytic converter
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

The digital warning light will flash and a specific message will appear on the
display (for versions/markets, where provided).
The digital warning light may flash in the following ways, depending on the
versions:
- for 1 minute every two hours;
- for 3 minute cycles with the warning light off for intervals of 5 seconds until
oil is changed.
After the initial warning, each time the engine is started up, the digital
warning light will continue to flash in the same mode, until the oil is
changed. A specific message will appear on the display (for versions/
markets, where provided) in addition to the warning light. If the digital
warning light flashes, this does not mean that the car is defective, but
simply informs the driver that it is now necessary to change the oil as a
result of regular vehicle use. Remember that the deterioration of engine oil
is accelerated by using the car for short drives, preventing the engine from
reaching operating temperature.
