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, dry grass or other
combustible materials. The DPF
regeneration process creates very high
exhaust gas temperatures and the
exhaust will radiate a considerable
amount of heat during and after DPF
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, occasional trips with the following
conditions could assist the regeneration
process:
Starting the engine
87
• Drive your vehicle, preferably on a
main road or motorway, for up to 20
minutes avoiding prolonged idling, but
always observing speed limits and
road conditions.
• Do not switch off the ignition.
• Use a lower gear than normal to
maintain a higher engine speed during
this journey, where appropriate.
