Symbol What it means
WATER IN DIESEL FILTER (Diesel versions)

presence of water in the diesel filter.

DPF CLEANING (particulate trap) in progress (diesel versions with DPF only)
(where provided)
The symbol switches on constantly to indicate that the DPF system needs to eliminate the trapped
pollutants (particulate) through the regeneration process.
The symbol stays off during the entire DPF regeneration and lights up only when driving
conditions require the driver to be notified. The symbol does not switch on during every DPF
regeneration, but only when driving conditions require that the driver is notified. To turn off the symbol,
keep the vehicle in motion until the regeneration process is over. The process normally takes about
15 minutes. Optimal conditions for completing the process are achieved by travelling at 60 km/h with
engine speed above 2000 rpm.
When this symbol switches on, it does not indicate a fault and thus it should not be taken to a workshop.
yellow
On some versions, together with the symbol switching on, the display shows a dedicated message.
IMPORTANT Failure to observe the appropriate procedure for a long distance when the symbol
comes on, can cause the warning light to come on, resulting in the need to go
to a Fiat Dealership to restore correct DPF operation.
