2 Manual 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 flash-
ing of the indicator lamp to perform the manual
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 manual DPF
regeneration in order to remove the PM inside
the DPF by oxidation.
3 How to perform the manual DPF regen-
eration
The manual DPF regeneration steps you should fol-
low upon flashing of the indicator lamp are indi-
cated below. You may perform the manual DPF
regeneration only when the indicator lamp
flashes. The manual DPF regeneration time is as a
general rule 10 to 30 minutes although it varies with
the conditions in which the vehicle is operated.
WARNING
Do not perform the manual DPF regeneration
in a poorly ventilated garage or other closed
area. Exhaust gas contains carbon monox-
ide, which is toxic and very dangerous.
