Starting the engine
•
•
Do not switch off the ignition.
Regeneration
Use a lower gear than normal to
maintain a higher engine speed during
this journey, where appropriate.
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.
SWITCHING OFF THE
ENGINE
Vehicles with a turbocharger
CAUTION
Do not switch the engine off when it
is running at high speed. If you do,
the turbocharger will continue
CAUTION
running after the engine oil pressure has
dropped to zero. This will lead to
premature turbocharger bearing wear.
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.
Release the accelerator pedal. Wait until
the engine has reached idle speed and
then switch it off.
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.
