DIESEL PARTICULATE
FILTER (DPF)
The DPF forms part of the emissions
reduction systems fitted to your vehicle.
It filters harmful diesel particulates (soot)
from the exhaust gas.
Regeneration
WARNING
Do not park or idle your vehicle over
dry leaves or dry grass or other
combustible material. The
regeneration process requires very high
exhaust gas temperatures and the
exhaust will radiate a considerable
amount of heat during and after
regeneration, and after you have switched
the engine off. This is a potential fire
hazard.
Unlike a normal filter which requires
periodic replacement, the DPF has been
designed to regenerate, or clean itself to
maintain operating efficiency. The
regeneration process takes place
automatically. However, some driving
conditions mean that you may need to
support the regeneration process.
If you drive only short distances or your
journeys contain frequent stopping and
starting, you must initiate the regeneration
process if the soot overload warning lamp
in the instrument cluster illuminates. See
Warning lamps and indicators
(page 56). When safe to do so:
•
Drive your vehicle on a free flowing
journey for up to 30 minutes, avoiding
prolonged idling.
•
Do not switch off the ignition.
•
Use a lower gear than normal to
maintain a higher engine speed during
this journey.
Starting the engine
85
This process may have to be repeated.
The warning lamp will go out when the
regeneration process is successful.
