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.
CAUTION
Avoid running out of fuel.
Note: After you have switched your
engine off the fans may continue to run
for a short period of time.
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, where there is increased
acceleration and deceleration, occasional
trips with the following conditions could
assist the regeneration process:
•
Drive your vehicle at a constant speed,
preferably on a main road or
motorway, for up to 20 minutes.
•
Avoid prolonged idling and always
observe speed limits and road
conditions.
Starting the engine
92
•
Do not switch off the ignition.
•
Use a lower gear than normal to
maintain a higher engine speed during
this journey, where appropriate.
