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 it 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
turn off the warning light, keep the car in motion
until the regeneration process is over.
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.
