DPF is short for “diesel particulate filter”. The DPF
system is essentially formed of a ceramic filter and
an oxidation catalyst. The ceramic filter collects
small particles (particulate matter or PM) contained
in diesel engine exhaust, while the catalyst works to
continuously regenerate the ceramic filter (or
remove the PM trapped by the filter by oxidation).
•
The regeneration controlling DPF system on
your vehicle can maintain its full PM removing
capability thanks to an automatic computer con-
trol it employs to actively regenerate the filter (or
remove the collected PM by oxidation) and thus
prevent an overfilled ceramic filter under low-
speed driving or similar conditions when contin-
uous filter regeneration is impossible (this is
called “automatic DPF regeneration”). However,
the automatic DPF regeneration cannot work in
such cases as extremely slow driving and fre-
quently repeated engine start and shutdown. If
the DPF is loaded with PM to its maximum
capacity following these types of driving, you
must manually regenerate it after bringing the
vehicle to a stop (this is called “parked DPF
regeneration”). The following table shows when
the system continuously or automatically regen-
erates the DPF and when you must manually
regenerate the DPF or have the system
inspected by an authorized dealer.

Normal speed driving
During high-speed or high-load driving,
filter trapped PM is removed continuously
by oxidation (continuous regeneration).
Automatic DPF
regeneration
When PM accumulates to a predeter-
mined amount, it is actively removed by
oxidation (automatic regeneration).

You must bring the vehicle to a stop and
perform the appropriate procedure to
clean out DPF (parked regeneration).
