Before you start manual regeneration, do
the following:
• Shift into park (P) and apply the
parking brake, on stable, level ground.
• Park your vehicle outside of any
structure.
• Park your vehicle 10–15 ft (3–5 m)
away from any obstructions and away
from materials that can easily combust
or melt, for example paper, leaves,
petroleum products, fuels, plastics and
other dry organic material.
• Make sure there is a minimum of 1/8
tank of fuel.
• Make sure all fluids are at proper levels.
DIESEL PARTICULATE FILTER
MANUAL REGENERATION
LIMITATIONS
You cannot use manual 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.
If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than 25 mph (40 km/h), short
drive cycles, drive time less than 15 minutes
or the vehicle does not fully warm up,
passive and active regeneration may not
sufficiently clean the diesel particulate
filter system.
Aftermarket devices or modifications to
the exhaust system may reduce the
effectiveness of the exhaust system as
well as cause damage to the exhaust
system or engine. This may also degrade
vehicle performance and could lead to
engine damage that may not be covered
by the vehicle Warranty.

STARTING DIESEL PARTICULATE
FILTER MANUAL REGENERATION
Start with your vehicle engine and when it
has reached the normal operating
temperature, press the information display
control button on the steering wheel. See
Instrument Cluster Display (page 141).
If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning
appears in the information display. See
Diesel Particulate Filter – Information
Messages (page 215). Answer yes to this
prompt and then follow the next prompts
regarding exhaust position required to
initiate manual 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 manual regeneration starts, engine
speed increases to approximately 1600
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 manual
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
