hours of engine operation.
For software 122-0251E and up: if
a parked regeneration is ignored, the

soon as possible. A parked regeneration
will take approximately 30 to 60 minutes
and should not be started with less than
1/4 tank of fuel. The machine must remain
stationary (cannot be operated) during
the entire parked regeneration process.
The engine ECU adjusts the exhaust
intake throttle to raise the exhaust
temperature.
For all software revisions: the InfoCenter
displays advisory #188 and/or the stationary
regeneration icon.
Manually initiate a recovery regeneration as
soon as possible. A recovery regeneration
will take approximately 3 hours and
should not be started with less than 1/2 tank
of fuel. The machine must remain stationary
