Procedure for Selectable Regeneration of DPD
Perform the selectable regeneration of the DPD when the engine (coolant temperature)
and exhaust pipe are still warm such as when the day's operation is finished.
CAUTION
• Perform the selectable regeneration until it is completed without interruption.
• Do not leave the vehicle during the regeneration.
• To prevent a fire, make sure that there are no flammables near the muffler, DPD
and exhaust pipe.
• Remember that the temperature of exhaust gases is high enough to burn you.
1. Stop the vehicle at a safe place free of flammable material such as dead grass or
wastepaper.
2. With the engine idling, ensure that the gearshift lever is placed in the "N" position
for a manual transmission model or place the gearshift lever in the "N" position for
a model with AMT. Then, confirm that the gearshift indicator shows "N" and fully
engage the parking brake. When the engine speed is increased by operating the
idling control knob in the vehicle equipped with the idling control knob, return the
engine speed to the normal idling state.
Make sure that the operation of PTO is stopped if your vehicle is equipped with a
PTO.
3. If your vehicle is not equipped with multi-information display (MID), press the
DPD switch until the DPD manual regeneration indicator light (amber) comes
on. The DPD manual regeneration indicator light (amber) will go from steadily on
to flashing. If your vehicle is equipped with MID, press the DPD switch until the
"CHECKING PM LEVEL" message (amber) is displayed. The "CHECKING PM
LEVEL" message (amber) will then change and "PUSH DPD SWITCH" message
(amber) with flashing.
