Selectable regeneration procedure

Your vehicle has the following selectable regeneration procedure in
case the driver is not able to perform the emergency regeneration for
some reasons when the DPF indicator light (amber/red) comes on.
Selectable regeneration may be performed when the engine (coolant
temperature) and exhaust pipe are warm after transport.
CAUTION: To prevent fire, ensure that there is no combustible
material near the DPF, exhaust pipe or muffler.
Be careful not to burn yourself on the hot exhaust gas.
CAUTION:
• Perform selectable regeneration without interruption.
• Stay near the vehicle during the regeneration.
1. Stop the vehicle in a safe place where there are no dead leaves,
scraps of paper or other substances that readily burn.
2. Idle the engine, then move the shift lever to the "N" or "P" position,
and pull the parking brake lever firmly. In the case of a vehicle
fitted with PTO (POWER TAKE-OFF) unit, confirm that operation
of the PTO has stopped.
NOTICE: If you used the idling control knob to increase the engine
speed, turn it all the way to the left to reduce the speed to normal
idling condition, and then perform the DPF regeneration.
