Maintenance and Specifications When the engine control module detects that the DPF is nearly full of particulates and that the vehicle is not being operated in a manner to allow effective automatic cleaning, the message center will display DRIVE TO CLEAN EXHAUST FILTER guiding the vehicle operator to drive in order to clean the DPF. If the vehicle is operated in a manner to allow effective automatic cleaning, the message center will display CLEANING EXHAUST FILTER, which is the normal regeneration process. See Message center in the Instrument Cluster chapter of the Owner Guide for more information. If the operator is not able to drive in manner that allows effective automatic cleaning (active regeneration) or the operator instead wishes to perform regeneration of the DPF (cleaning) while at idle (stationary), then OCR (operator commanded regeneration) will need to be performed. See Operator commanded regeneration (OCR) following. Note: Do not disregard the DRIVE TO CLEAN EXHAUST FILTER maintenance message for extended periods of time. Failure to perform active or operator commanded regeneration (OCR) (if equipped) when instructed may result in a clogged DPF. If your DPF fills beyond what can be safely regenerated, active regeneration and OCR will be disabled. This could cause irreversible damage to the DPF, requiring service and possible replacement that may not be covered by your warranty. Operator commanded regeneration (OCR) (if equipped) If your vehicle is operated with significant stationary operation, passive and active regeneration may not sufficiently clean the DPF system. OCR allows you to manually start regeneration of the diesel particulate filter (DPF) at idle (while stationary) to clean the DPF. If you are not sure whether your vehicle is equipped with this feature, contact your authorized dealer. When to perform OCR Use the OCR feature when the DRIVE TO CLEAN EXHAUST FILTER message appears in the message center and: • the operator is not able to drive in manner that allows effective automatic cleaning (active regeneration), • or the operator instead wishes to manually start regeneration (cleaning) of the DPF while the vehicle is idle (stationary). 56 2011 Diesel (eco) Supplement, 5th Printing USA (fus)

When the engine control module detects that the DPF is nearly full of
particulates and that the vehicle is not being operated in a manner to
allow effective automatic cleaning, the message center will display
DRIVE TO CLEAN EXHAUST FILTER
guiding the vehicle operator to
drive in order to clean the DPF. If the vehicle is operated in a manner to
allow effective automatic cleaning, the message center will display
CLEANING EXHAUST FILTER
, which is the normal regeneration
process. See
Message center
in the
Instrument Cluster
chapter of the
Owner Guide
for more information.
If the operator is not able to drive in manner that allows effective
automatic cleaning (active regeneration) or the operator instead wishes
to perform regeneration of the DPF (cleaning) while at idle (stationary),
then OCR (operator commanded regeneration) will need to be
performed. See
Operator commanded regeneration (OCR)
following.
Note:
Do not disregard the
DRIVE TO CLEAN EXHAUST FILTER
maintenance message for extended periods of time. Failure to perform
active or operator commanded regeneration (OCR) (if equipped) when
instructed may result in a clogged DPF. If your DPF fills beyond what
can be safely regenerated, active regeneration and OCR will be disabled.
This could cause irreversible damage to the DPF, requiring service and
possible replacement that may not be covered by your warranty.
Operator commanded regeneration (OCR) (if equipped)
If your vehicle is operated with significant stationary operation, passive
and active regeneration may not sufficiently clean the DPF system. OCR
allows you to manually start regeneration of the diesel particulate filter
(DPF) at idle (while stationary) to clean the DPF. If you are not sure
whether your vehicle is equipped with this feature, contact your
authorized dealer.
When to perform OCR
Use the OCR feature when the
DRIVE TO CLEAN EXHAUST FILTER
message appears in the message center and:
•
the operator is not able to drive in manner that allows effective
automatic cleaning (active regeneration),
•
or the operator instead wishes to manually start regeneration
(cleaning) of the DPF while the vehicle is idle (stationary).
