Diesel particulate filter regeneration (Caterpillar engine only)
DPF regeneration requires no operator interaction and may occur at any
time. A small increase in engine sound-level during filter regeneration is
normal and should be no reason for concern.
A separate fuel injector/nozzle, which requires periodic cleaning, is used
in the regeneration process. Refer to Caterpillar’sOperation and
Maintenance Manualfor details regarding cleaning requirements.
Diesel particulate filter regeneration (Cummins engine only)
Under most operating conditions, DPF regeneration will be transparent
to the operator. A small increase in engine/turbo sound-level is normal
during filter regeneration. If, however, your engine is operated for
extended periods of time under one of the following conditions, operator
assistance may be required to facilitate the filter regeneration process:
•Vehicle is operated in stop-and-go traffic and/or maintains low speeds
as in a city/delivery driving
•Engine is started and shut-off frequently
•Vehicle payload is relatively light
•Vehicle is regularly operated in cold ambient temperatures (i.e. below
0°F [-18°C])

Instrument cluster lamp(s) will
illuminate and/or flash when
operator assistance is required. In
addition, engine performance will
become increasingly limited above
Level 1.
At Levels 1 and 2, two courses of action may be taken by the operator to
facilitate filter regeneration:
1. The vehicle may be driven on the highway at highway speeds,
2. The operator may perform a parked regeneration by following the
steps inParked regeneration procedure (Cummins engine only).
At Level 3, performing a parked regeneration is the only available course
of action (short of professional servicing) available to the operator for
regenerating the filter. At Level 4, professional servicing is the only way
to regenerate the filter.
Parked regeneration procedure (Cummins engine only)
WARNING:When performing the parked regeneration
procedure, make certain the vehicle is safely off roadway, and
the exhaust system is away from people, or any flammable materials,
vapors, or structures. Engine speed may increase during parked
regeneration.
Note:Parked regeneration is only available when the DPF lamp on the
instrument cluster is illuminated (solid or flashing).
1. Bring the vehicle to a complete stop on level ground and safely off the
road with the exhaust system away from people, flammable materials,
vapors or structures.
2. If your vehicle is equipped with an automatic transmission and a
steering column shift lever, place transmission in P (Park). Otherwise,
place the transmission in N (Neutral).
3. Remove feet from the accelerator pedal and clutch pedal (if
equipped).
4. Set the parking brake.
5.Within 5 seconds of setting the parking brake,remove foot from
the service brake pedal.

The engine speed may increase slightly. To allow parked regeneration to
continue uninterrupted:
1. The vehicle must remain parked
2. The transmission must remain in P (Park) or N (Neutral) (as
previously described in Step 2).
3. The accelerator pedal, service brake pedal, and clutch pedal (if
equipped) must not be pressed
4. The parking brake must remain set
On average (depending on filter level and other factors), the process will
take 20–30 minutes to complete. The DPF lamp will turn off when the
process is complete. Repeat Steps 1–5, if parked regeneration is interrupted.
To discontinue parked regeneration (Cummins engine only)
Press any of the floor pedals to discontinue parked regeneration.
Diesel particulate filter maintenance and service
The DPF is designed to retain a relatively large amount of residual ash
and provide many miles and hours of maintenance-free operation. At
some point, generally beyond 150,000 miles (240,000 km) or 5,000 hours
of operation (whichever comes first), the DPF will require professional
cleaning to remove the accumulated ash
The exact number of miles or hours of operation will vary greatly
depending upon vehicle/engine loading and operating conditions, ash
content of the engine oil, and quality of the diesel fuel used in your
truck. Adhering to your engine manufacturer’s recommended oil and fuel
specifications will maximize the miles and hours of operation before a
DPF professional cleaning is required. Refer to your engine
manufacturer’s owner’s manual for more details regarding recommended
maintenance and service of your DPF.
Exhaust outlet assembly
WARNING:The normal operating temperature of the exhaust
system is very high. Never work around or attempt to repair any
part of the exhaust system until it has cooled. Failure to follow these
instructions may result in serious personal injury.
The exhaust outlet assembly on your vehicle is a uniquely functioning
device that accompanies the DPF assembly. It is designed to help control
the temperature of the exhaust during the DPF regeneration process.Do
Maintenance and Specifications

not modify or remove this device. Modification of the system
and/or additions of aftermarket devices can reduce the
effectiveness of the system, as well as cause damage to the
exhaust system and/or engine. Any modifications may also
invalidate the vehicle and/or engine warranties. See the vehicle
and engine warranty guides for more information.
The inlet holes in the side of the assembly are functional. These holes
allow outside air to be drawn into the outlet assembly. The holes need to
be kept clear of mud and other foreign material to maintain proper
functionality of the system. One way to keep the holes clear is to spray
the outlet assembly with a hose when washing the vehicle. Failure to
keep the functional holes clear of foreign material may result in the holes
becoming blocked or plugged.Blocked/plugged holes or
modification/removal of the outlet assembly could result in
elevated exhaust temperatures which may result in
vehicle/property damage and/or personal injury.
NOISE EMISSIONS – EXTERIOR
In order to comply with the federal exterior noise regulations, your
vehicle may be equipped with noise emission items. Depending on the
vehicle configuration, it may have all or some of the following items:
Air Intake System
•Air Cleaner:should be inspected and its location should not be
altered. Do not alter inlet and outlet piping.
Body
•Wheel Well:splash shields, cab shields and under-hood insulation
should be inspected for deterioration, dislocation, and orientation.
Cooling System
•Check the fan for damage to blades; replace, if damaged, with the
