OCR precautions and safe exhaust position
WARNING:Failure to comply with the following instructions for
operator commanded regeneration (OCR) may result in fire,
serious injury, death and/or property damage.
Before you start OCR, observe/do the following:
•Place the vehicle in P (Park) with the parking brake set on stable,
level ground.
•The vehicle must not be parked in a structure.
•The vehicle must be 10 – 15 feet (3 – 5 meters) away from any
obstructions,
•and must be away from materials that can easily combust or melt such
as: paper, leaves, petroleum products, fuels, plastics and other dry
organic material, such as grass.
•Make sure there is a minimum of 1/8 tank of fuel.
•Make sure all fluids are at proper levels.
Make sure that the louvers (holes) located at the tip of the exhaust are
also clear of any obstructions as they are used to introduce fresh air into
the tailpipe to cool the exhaust gas as it leaves. SeeExhaustunder the
Cleaningchapter for more information.
How to start operator commanded regeneration (OCR)
WARNING:Stay clear of exhaust tip during regeneration. You or
others can be burned.
Note:OCR will not be allowed until DPF load percentage has reached
100% (Full). The DPF load percentage will fluctuate up and down when
driving your vehicle due to active and passive regenerations.
Note:During the use of OCR, you may observe a light amount of white
smoke. This is normal.
OCR will not be allowed to operate
if the service engine soon light is
illuminated

How to interrupt/cancel OCR
If OCR needs to be cancelled, pressing the brake, accelerator, or shutting
off the vehicle will stop OCR. Depending on the amount of time OCR was
allowed to operate, soot may not have had sufficient time to be
eliminated, but the exhaust system and exhaust gas may still be hot. If
the vehicle is shut off during OCR, you will notice turbo flutter. This is a
normal consequence caused by shutting off a diesel engine during
boosted operation and is considered normal.
Filter service/maintenance
Over time a slight amount of ash will build up in the DPF which is not
removed during the regeneration process. The DPF may need to be
removed for ash cleaning at approximately 120,000 miles (193,000 km)
or greater (actual mileage can vary greatly depending upon
engine/vehicle operating conditions) and replaced with a new or
remanufactured (ash cleaned) part. The filter may need to be replaced
at approximately 250,000 miles (400,000 km) depending upon
engine/vehicle operating conditions.
In both cases the engine control
system will set a service light to
inform you to bring the vehicle to
the dealer for service.
If there are any issues with the
oxidation catalyst/DPF system a
service light will be set by the
engine control system to inform you
to bring the vehicle into your
authorized dealer for service.
