DIESEL PARTICULATE FILTER (DPF)
(for versions/markets where provided)
The Diesel Particulate Filter is a mechanical filter, inte-
gral to the exhaust system, that physically traps particu-
lates present in the exhaust gases of diesel engines.
It is needed to eliminate almost all particulates in compli-
ance with current/future legislation.
During normal use of the vehicle, the engine control unit
records a set of data (e.g. travel time, type of route, tem-
peratures, etc.) and it will then calculate how much par-
ticulate has been trapped by the filter.
Since this filter physically traps particulate, it should be re-
generated (cleaned) at regular intervals by burning the car-
bon particles.
The regeneration procedure is handled automatically by
the engine control unit according to the filter conditions
and vehicle use conditions.
During regeneration, the following may occur: a limited in-
crease in the engine speed, activation of the fan, a limited
increase in fumes and high temperatures at the exhaust.
These are not faults; they do not impair vehicle perfor-
mance or damage the environment.
If the dedicated message is displayed, refer to the “Warn-
ing lights and messages” section.
The diesel particulate filter (DPF) (for ver-
sions/markets where required) reaches
high temperatures during normal operation.
Therefore do not therefore park the vehicle on in-
flammable materials (grass, dry leaves, pine nee-
dles, etc.): fire hazard.
WARNING
The catalytic converter also reaches high
temperatures during normal operation.
Do not park the vehicle on grass, dry leaves, pine
needles or other flammable material: fire hazard.
