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.
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.
Starting the engine
132
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 will
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.
Do not switch off the ignition.
Use a lower gear than normal to
maintain a higher engine speed during
this journey, where appropriate.
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
running after the engine oil pressure has
dropped to zero. This will lead to
premature turbocharger bearing wear.
Release the accelerator pedal. Wait until
the engine has reached idle speed and
then switch it off.

ENGINE HEATER

CAUTION
Make sure you disconnect the power
cable from the engine heater
connector before driving away.
Note: The engine heater connector is
located in the front bumper.
