STARTING AND
(for versions/markets, where provided)
DRIVING
The Diesel Particulate Filter is a mechanical filter, integral to the
exhaust system, that physically traps carbon particles present in the
exhaust gases of diesel engines.
The diesel particulate filter is needed to eliminate almost all carbon

particle emissions in compliance with current/future regulations and
standards.
During standard use of the vehicle, the engine control unit records a set
of data (e.g.: travel time, type of route, temperatures, etc.) and it will

INDEX
108
Since this filter physically traps particulate, it should be periodically
regenerated (cleaned) at regular intervals by burning carbon particles.
The regeneration procedure is controlled automatically by the engine
management control unit according to the filter conditions and vehicle
use conditions.
During the regeneration there may be a limited increase in the engine
idle speed, fan activation, a limited increase in fumes and high
temperatures at the exhaust.
These are not faults; they do not impair normal car performance or
damage the environment. If the dedicated message is displayed, see
contents of "Warning lights and messages" paragraph.
The catalytic converter and particulate filter (DPF) reach
very high temperatures during operation. Therefore
do not park the car on flammable materials (grass, dry
leaves, pine needles, etc.): fire hazard.
