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 51). 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
This process may have to be
repeated. The warning lamp will go
out when the regeneration process
is successful.
