Technical Information
CATALYTIC CONVERTER
The PM will be burnt out and
removed from the DPF at a
periodically high temperature of the
catalytic converter. While the PM is
burnt, you may notice some white
smoke in the exhaust gas.
The DPF system requires no regular
maintenance. If you drive for long
periods at slow speeds, particulate
matter (PM) will be accumulated
and the regeneration of DPF will be
required. The condition of the
accumulated PM will vary with the
type of diesel fuel. Always use the
recommended diesel fuel in this
owner's manual (see page 184 ).
