CONTROLS AND INSTRUMENTS
The DPD purifies particulate matter (PM) in exhaust gases. The DPD collects PM in
the DPD filter and when PM is collected in the filter to the predetermined level, the
DPD automatically burns PM (regeneration the filter). We recommend that you observe
the following instructions to keep the DPD in order.

The DPD switch is used to manually burn
PM (regenerate the filter).
You should take the steps for manually
regenerating the DPD when the DPD
manual regeneration indicator light (amber)
flashes if your vehicle is not equipped with
multi-information display (MID) (the flashing
occurs at about one-second intervals and
is accompanied by "a short beep" of a
warning buzzer), or when the "PUSH DPD
SWITCH" message (amber) flashes if your
vehicle is equipped with MID (the flashing
occurs at about one-second intervals and
is accompanied by "short, repeated beeps"
of a warning buzzer). Perform the manual
regeneration of the DPD while parking
the vehicle after the day's operation, for
example, following the instructions under
"DPD Manual Regeneration Procedure".
If you continue driving with the light or
message flashing at about once per
second (1 Hz) intervals, the flashing
intervals will change to shorter ones (about
3 times per second (3 Hz) intervals). If you
continue driving in this state too long, the
DPD may fail. Stop the vehicle at a safe
place immediately and perform the manual
regeneration.
