DURAMAX Diesel Engine (LML/LGH) - 2011
Driving and Operating 9-11
The DPF will clean itself as part of
normal operation. Several factors
including fuel consumed, hours of
engine operation and miles driven
are monitored by the Engine Control
Module (ECM). The self-cleaning
occurs approximately once per tank
of fuel.
Notice: Permanent damage
can occur to the DPF or related
components if the required Ultra
Low Sulfur Diesel (15 ppm sulfur
maximum) or low ash CJ4 engine
oil is not used. This damage
would not be covered by the
vehicle warranty.
Under certain driving conditions,
such as stop and go traffic, the filter
cannot clean itself. The CLEANING
EXHAUST FILTER KEEP DRIVING
UNTIL MESSAGE IS CLEARED
message comes on when the DPF
is dirty and needs to perform a
selfcleaning.
For the filter to clean itself, the
vehicle must be driven above
50 km/h (30 mph) until the
CLEANING EXHAUST FILTER
KEEP DRIVING UNTIL MESSAGE
IS CLEARED message goes off.
This will take about 30 minutes.

WARNING
During DPF self cleaning or
during extended idling in P (Park),
the exhaust system and exhaust
gases are very hot. Things that
burn could touch hot exhaust
parts under the vehicle and
ignite. You or others could be
burned. Do not park, or idle for an
extended period of time, near or
over papers, leaves, dry grass,
or other things that can burn.
Keep the exhaust area clear of
material that could ignite or burn.
See Parking Over Things That
Burn on page 910 for more
information.
Notice: Extended idle should be
avoided because the DPF system
is not capable of self cleaning
at idle. During extended idle
operation, monitor the instrument
panel telltale lights and Driver
Information Center for messages
and take appropriate indicated
action. Continued idling with the
warning light/message on could
cause irreversible damage to the
DPF requiring repair and possible
replacement that might not be
covered by the vehicle warranty.
You will also notice a change in
the exhaust sound and engine idle
speed. This is normal. See Vehicle
Messages on page 510.
If you continue to drive with the
DPF warning message on and the
exhaust filter is not cleaned as
required, the Malfunction Indicator
Lamp and the ENGINE POWER IS
REDUCED message will come on
and dealer service is necessary.
See Malfunction Indicator Lamp on
page 56 and Engine Power
Messages on page 511.
