1 Automatic DPF regeneration
The system actively removes PM by oxidation to
prevent an overfilled DPF under automatic control.
The operating sound and idling speed of the engine
will change but you can drive the vehicle in its nor-
mal manner.
NOTE:
•
During the automatic DPF regeneration, there
may be a change in engine operating sound
and, when your vehicle is in park, a rise in idling
speed (to approx. 750 rpm) accompanied by
exhaust brake valve operation. These do not
indicate any abnormalities.
•
Exhaust temperature is higher when the auto-
matic DPF regeneration is taking place.
2 Parked DPF regeneration (performed
following illumination of the indica-
tor lamp)
The system sometimes cannot automatically
remove the DPF trapped PM by oxidation, typically
when you drive the vehicle at very low speeds or
start and stop the engine frequently during opera-
tion. The system informs you of such a condition by
flashing the indicator lamp to prompt you to
manually remove the DPF trapped PM by oxidation.
The flashing interval of the indicator lamp differs
depending on the amount of the PM accumulated in
the DPF as follows:
•
Slow flashing (1-second interval)
You must use the DPF cleaning switch within 50
km (31 miles) of driving after the start of the
flashing of the indicator lamp to perform the
parked DPF regeneration in order to remove the
PM inside the DPF by oxidation.
•
Fast flashing (0.3-second interval)
You must bring the vehicle to a stop in a safe
place as soon as possible, then use the DPF
cleaning switch to perform the parked DPF
regeneration in order to remove the PM inside
the DPF by oxidation.
NOTE:
If prompted by a fast flashing of the indicator
lamp for PM removal from the DPF, you must per-
form the parked DPF regeneration without any
delay. Continuing to drive with an overfilled DPF will
result in system failure.
