If the warning light remains on or switches on whilst
driving, it means that the injection system is not working
properly. In particular, the warning light on constantly
signals a malfunction in the injection/ignition system
which could cause high exhaust emissions, a possible
loss of performance, poor driveability and high
consumption.
On some versions, the display shows the dedicated
message.
The warning light goes out after the fault disappears: the
indication is stored in 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 an Alfa Romeo Dealership as
soon as possible.
Petrol engines only
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. Continue the journey at moderate
speed, trying to avoid driving conditions
that may cause further flashing and
contact an Alfa Romeo Dealership as
soon as possible.

KNOWING THE INSTRUMENT PANEL

Warning lights on
panelWhat it means What to do
amberDPF CLEANING (particulate trap) in progress
(diesel versions with DPF only)
When the key is turned to MAR-ON, the warning
light switches on but should switch off after a few
seconds.
The warning light switches on constantly to
indicate that the DPF system needs to eliminate
the trapped pollutants (particulate) through the
regeneration process.
The warning light does not come on during every
DPF regeneration, but only when driving
conditions require that the driver is notified. To
switch the warning light off, the car must be kept
moving until the regeneration process is
completed.
On average, the process lasts 15 minutes.
Optimal conditions for completing the process are
achieved by travelling at 60 km/h with engine
speed above 2000 rpm.
When this warning light switches on, it does not
indicate a car failure and thus it should not be
taken to a workshop.
On some versions, together with the warning light
switching on, the display shows a dedicated
message.

WARNING
69) Always drive at a speed appropriate to the traffic conditions, the weather and traffic regulations. The engine can be
stopped even if the DPF warning light is on: however, repeated interruptions of the regeneration process could cause
premature deterioration of the engine oil. For this reason, always wait until the warning light switches off before
stopping the engine as described above. It is not advisable to complete DPF regeneration with the car stationary.
