PROTECTING
THE ENVIRONMENT
The following devices are used for
reducing petrol fuel engine emissions:
❒ three-way catalytic converter;
❒ oxygen sensors;
❒ evaporation control system.
In addition, do not let the engine run,
even for a test, with one or more spark
plugs disconnected.
The following devices are used
for reducing diesel fuel engine emissions:
❒ oxidising catalytic converter;
❒ exhaust gas recirculation system
(EGR);
❒ diesel particulate filter (DPF).
The catalytic converter
develops high temperature
during operation. Do not park
the vehicle on grass, dry leaves,
pine needles or other flammable
material: fire hazard.

DIESEL PARTICULATE FILTER
(DPF) (for 1.3L Duratorq versions)
The Diesel Particulate Filter is
a mechanical filter, integral with
the exhaust system, that physically
traps particulates present in
the exhaust gases of diesel engines.
The diesel particulate filter has been
adopted to eliminate almost all
particulates in compliance with current/
future legal regulations.
During normal 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 then
calculate how much particulate has
been trapped by the filter.
Since this filter physically traps
particulate, it should be regenerated
(cleaned) at regular intervals by burning
carbon particles.
WARNING
The regeneration procedure
is controlled automatically by the engine
management control unit according
to the filter conditions and car
use conditions.
There may be a limited increase
in the engine idle speed during the
regeneration, a limited increase in fumes
and high temperatures at the exhaust.
These are not failures; they do not
impair vehicle performance or damage
the environment. If the dedicated
message is displayed, refer to paragraph
"Warning lights and messages".
