How to Start Operator Commanded
Regeneration
WARNING
Stay clear of the exhaust tailpipe
during regeneration. Hot exhaust
gases can burn you badly.
Note: You cannot use the operator
commanded regeneration until the diesel
particulate filter load percentage has
reached 100%. The diesel particulate filter
load percentage fluctuates up and down
when driving your vehicle due to active and
passive regenerations.
Note: During the use of operator
commanded regeneration, you may observe
a light amount of white smoke. This is
normal.
You may not be able to use
operator commanded
regeneration if the service engine
soon warning lamp appears in the
information display
Information Display Procedure
Start your vehicle engine and when it has
reached the normal operating temperature,
press the information display control
button on the steering wheel until Exhaust
Filter XX%/FULL is displays. Operator
commanded regeneration can only be
initiated when FULL See Information
Display Control (page 47). If a message
advising that the exhaust filter is full
appears in the information display, press
the down arrow button to set the display
to Y. Answer yes to this prompt and then
follow the next prompts regarding exhaust
position required to initiate operator
commanded regeneration. Be sure to
understand each prompt. If you are not
sure what is being asked by each prompt,
contact an authorized dealer. The display
confirms the operation has started and
when it has finished.

If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning
appears in the information display only if
viewing the Exhaust Filter Status message.
See Information Messages (page 66).
Answer yes to this prompt and then follow
the next prompts regarding exhaust
position required to initiate operator
commanded regeneration. Be sure to
understand each prompt. If you are not
sure what is being asked by each prompt,
contact an authorized dealer. The display
confirms the operation has started and
when it has finished. You can also drive to
clean the filter.
When the system is at the point
of oversaturation, the service
engine warning lamp illuminates
and a message appears in the information
display. You cannot initiate filter cleaning.
You must have your vehicle checked as
soon as possible.
Once operator commanded regeneration
starts, engine speed increases to
approximately 2000 rpm and the cooling
fan speed increases. You will hear a
change in audible sound due to engine
speed and cooling fan speed increases.
It is not necessary to open the hood on the
engine compartment. Once operator
commanded regeneration completes, the
engine speed returns to normal idling. The
exhaust system remains very hot for
several minutes even after regeneration is
complete. Do not reposition the vehicle
over materials that could burn until the
exhaust system has had sufficient time to
cool. Depending on the amount of soot
collected by the diesel particulate filter,
ambient temperature and altitude,
operator commanded regeneration lasts
approximately 30 minutes.
