Operation
Starting regeneration of the diesel particulate filter manually (parked regeneration)
Starting regeneration of the diesel
particulate filter manually (parked
regeneration)
Pull over safely with regard for other
traffic and leave the engine running.
Be sure to park well clear of other
vehicles, objects and all flammable
materials.
Danger.
Very hot exhaust fumes are expelled from
the exhaust tail pipe during the manual
regeneration process (parked regenera-
tion). Keep well clear of the exhaust tail
pipe. Otherwise, you could be burned by
the fumes.
Caution:
Only carry out manual regeneration out-
doors or in well-ventilated rooms. The
use of an extraction system should be
avoided because this will generally not
have been designed to withstand the ex-
haust temperature levels that arise.
Caution:
Make sure that no highly flammable ma-
terials, e.g. dry grass or fuels, come in-
to contact with the exhaust system dur-
ing the manual regeneration process
(parked regeneration). Do not leave the
bus parked up at a filling station, on dry
grass or on harvested crop fields. The
hot exhaust system could otherwise cause
the highly flammable material to ignite
and set the bus on fire.
Note:
Under normal circumstances, automatic
regeneration of the diesel particulate filter
is sufficient to avoid heavy soot loading
of the filter. However, if the bus is pre-
dominantly driven short distances or with
the engine under low load, it might not
be possible for automatic regeneration to
finish successfully.
Note:
If the diesel particulate filter load state
becomes critical, a yellow "particle filter"
indicator lamp lights up in the instrument
cluster. The on-board computer then dis-
plays a yellow event window prompting
you to start manual regeneration. The
manual regeneration process lasts approx-
imately 30 to no more than 60 minutes.
Apply the parking brake.
Shift the transmission to neutral N.
Take your foot off the accelerator
pedal.
If active, deactivate the regeneration
inhibitor.
Note:
refer to “Inhibiting automatic regeneration
of the diesel particulate filter”.
