Base information display procedure
1. Start with the vehicle engine fully warmed.
2. Press the Info button on the steering wheel until the information
display reads one of the following choices:
•
If the DPF needs cleaning and the vehicle is warmed up, a message
requesting permission to initiate filter cleaning will be displayed
EXHST XX% FULL CLEAN Y/N
or
EXHAUST FILTER FULL
.
Answer yes to this prompt and then follow the prompts regarding
exhaust position as needed to initiate OCR. Be sure to understand
each prompt. If you are not sure what is being asked by each prompt,
contact your authorized dealer. The display will confirm the operation
has started and when it has finished.
•
If the vehicle is warmed up, the

CLEAN? Y/N
. Answer yes to this prompt and then follow the
prompts regarding exhaust position as needed to initiate OCR. Be sure
to understand each prompt. If you are not sure what is being asked by
each prompt, contact your authorized dealer. The display will confirm

•
The service engine soon light will
illuminate and the following
messages
EXH OVERLOADED
CLEAN? Y/N
+
REDUCED ENGINE POWER
will appear when the
system is at the point of oversaturation you will not be able to allow
cleaning . The vehicle must be serviced by an authorized dealer.
3. Once OCR starts, the engine’s rpm will rise to approximately 2,000 -
2,400 rpm and the cooling fan will increase speed; you will hear a change
in audible sound due to the fan and engine speed increase.
It is not necessary to open the hood on the engine compartment. Once
OCR is complete, the engine rpm and fan will return to normal idling.
The exhaust system will remain 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 DPF, ambient
temperature, and altitude, OCR may last from 10 to 25 minutes.
