Note: During regeneration at low speed or
engine idle, you may smell a hot metallic
odour and could notice a clicking metallic
sound. This is due to the high temperatures
reached during regeneration and is normal.
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 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 BLOCK 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.
Connect the engine heater for two to three
hours before starting the engine.
