I - INSTRUCTIONS FOR CARRYING OUT A
FORCED REGENERATION OF THE PARTICLE
FILTER
Precautions to be taken during forced regeneration
of the particle filter
a There are currently two additional kits for extracting
exhaust gas in the workshop (see garage equip-
ment catalogue 2005), both of which are approved
for use at the high temperatures produced during
forced regeneration of the particle filter.
The two kits approved for particle filter regeneration
are:
- the particle filter kit for use with vehicles fitted
with a single exit silencer,
- the twin exhaust pipe kit for use with vehicles
equipped with a twin exhaust pipe on the silencer.
IMPORTANT
During forced regeneration of the particle filter,
the temperature of the exhaust pipe rises signifi-
cantly.
Always use one of the two kits approved for the
high temperatures reached during forced regen-
eration, whether the operation is carried out in
the workshop using an exhaust gas extractor, or
outside the workshop.
Ensure that when in use, the kit is not touching
the rear bumper when carrying out forced regen-
eration of the particle filter.

Note:
When using a kit for a twin exhaust pipe (1) on a
single exhaust pipe, be sure to:
- place an exhaust gas extractor over the open-
ings (2) and (3) if the forced regeneration is car-
ried out in the workshop,
- that the openings (2) and (3) , are positioned to
direct the hot exhaust gases away from another
vehicle or person, if the operation is carried out
outside the workshop.
