The PM will be burnt out and
removed from the DPF at a
periodically high temperature of the
catalytic converter while driving.
While the PM is burnt, you may
notice some changes on the
instrument panel and the exhaust
gas. You may notice some white
smoke in the exhaust gas. The
average fuel consumption on the
multi-information display will be
increased temporarily.
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 t he
recommended diesel fuel in this
owner’s manual (see page ).
If you see this symbol or this symbol
with a ‘‘DPF REGENERATION
REQUIRED’’ message on the multi-
information display while the engine
is running, it means the diesel
particulate filter (DPF) should be
regenerated to remove the
accumulated particulate matter (PM).
Your vehicle is equipped with the
diesel particulate filter ( DPF) system
to remove the particulate matter
(PM) from the exhaust gas. The
DPF is installed in the catalytic
converter.
