3. Do not press the accelerator pedal, service brake pedal, or clutch
pedal (manual transmission).
4. The parking brake must remain set.
On average, depending on filter level and other factors, the process takes
20–30 minutes to complete. The DPF lamp turns off when the process is
complete. Repeat Steps 1–5, if parked regeneration is interrupted.
To Discontinue Parked Regeneration
Press any of the floor pedals to discontinue parked regeneration.
Maintenance and Service
The DPF can retain a relatively large amount of residual ash and provide
many miles and hours of maintenance-free operation. At some point,
generally beyond 150000 miles (240000 kilometers) or 5000 hours of
operation (whichever comes first), the DPF requires professional
cleaning to remove the accumulated ash.
The exact number of miles or hours of operation vary greatly depending
upon vehicle and 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
maximizes the miles and hours of operation before a DPF professional
cleaning is required. See your engine manufacturer’s owner’s manual for
more details about 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.
Note:Do not modify or remove this device. Modification of the system
or additions of aftermarket devices can reduce the effectiveness of the
system, as well as cause damage to the exhaust system or engine. Any
modifications may also invalidate the vehicle or engine warranty. See
your warranty information.
Note:Blocked or plugged holes or modification to, or removal of, the
outlet assembly could result in elevated exhaust temperatures that may
result in vehicle or property damage or personal injury.
The exhaust outlet assembly on your vehicle is a uniquely functioning
device that accompanies the DPF assembly. It can help control the
temperature of the exhaust during the DPF regeneration process.

•DEF freezes below 12°F (-11°C). Your vehicle is equipped with an
automatic pre-heating system which allows the DEF system to
operate below 12°F (-11°C).
•Do not store the DEF bottle in your vehicle. If it leaks, it could cause
damage to interior components or release an ammonia odor inside
your vehicle.
•Store DEF out of direct sunlight and in temperatures between
23°F–68°F (-5°C–20°C).
NOISE EMISSIONS
In order to keep to the federal exterior noise regulations, your vehicle
may be equipped with noise emission items. Depending on your vehicle
configuration, it may have all or some of the following items:
Air Intake System:Inspect the air cleaner. Do not alter its location. Do
not alter inlet and outlet piping.
Body:Inspect wheel well splash shields, cab shields and under hood
insulation for deterioration, dislocation and orientation.
Cooling System:
•Inspect the fan for blade damage. If you find any damage, replace
with the recommended parts. Inspect for fan-to-shroud interference
and any damage to shroud, such as cracks and holes.
•Do not change fan ratio or alter fan spacer dimensions and positions.
•Inspect fan clutch for proper operation. Make sure the fan is
disengaged when cooling of the engine is not required.
•Inspect radiator shutters (if equipped) for proper operation. The
shutters should be open during normal operating temperatures.
Engine:Valve covers and block covers damp-out engine mechanical
noise. If they need replacing, make sure to replace them with the
recommended parts. Check for mechanical isolations.
Transmission Enclosure:Inspect for cracks, holes and tears. Clean any
deposits, such as oil, dirt and stones.
Exhaust System:
•Inspect for leaks at various joint connections and loose clamps.
•
Perform a visual inspection for cracks or holes in the muffler and tail pipe.
•Always use the recommended replacement parts.
•Do not change the tail pipe elbow or offset tail pipe orientation from the
standard position as originally received.
•To avoid abnormal changes in vehicle sound levels, it is necessary for the
owner to perform inspections and necessary maintenance at the intervals
shown in theScheduled Maintenancechapter.

more quickly. If you force the gearshift lever into position, this action
defeats the purpose of the synchronizer by causing gear clash.
Shifting with a Non-Synchronized Transmission
SeeClutch brakeandDouble clutch proceduresin theClutchsection
of this chapter.
Clutch
Do not ride or slip the clutch as this causes unnecessary heat and wear.
Maintain the specified clutch adjustment to prolong its life and regularly
inspect the clutch control linkage for tightness. See theScheduled
Maintenancechapter for other maintenance information. When
adjustment of the clutch is necessary, it is very important that the work
be performed properly or early clutch failure may result and a costly
clutch overhaul may become necessary. Only a qualified technician
should perform clutch work.
Note:Continued use of a damaged or worn clutch, prolonged clutch
slippage or downshifting at excessive speeds can result in a failure of the
engine, transmission or clutch components.
Note:To avoid premature clutch wear and failure, do not drive with
your foot resting on the clutch pedal or use it to hold your vehicle at a
standstill on an upgrade as when waiting for a traffic light.
Engaging the Clutch
•Always start in the proper gear. An empty vehicle can start in a
higher gear than a fully loaded vehicle. Starting in too high a gear can
cause clutch slippage and excessive heat and wear on the clutch. A
gear that starts the vehicle moving at idle speed is the correct gear. If
you have to rev the engine to get your vehicle going, the gear
selection is too high.
•Do not shift until your vehicle has reached the proper speed.
Upshifting before your vehicle has reached the proper speed can
cause clutch slippage and excessive heat and wear on the clutch.
•Never hold a vehicle on a grade with the clutch. This causes the
clutch to slip and can actually burn up the clutch.
•Never coast with the clutch disengaged. The high RPM (sometimes
over 10000) can actually burst the facing material of the clutch.
•Never engage the clutch while coasting. Re-engaging the clutch after
coasting may not only cause a great shock to the clutch, but the
whole drivetrain. Internal engine damage or clutch and flywheel
failure can result from this.

Allison 3000 Prognostics
This transmission is equipped with the Allison Prognostics feature that
can alert the driver to needed transmission maintenance and
transmission fluid and filter life. See the separate Allison transmission
manual for complete details.
POWER TAKE-OFF (PTO) OPERATION (IF EQUIPPED)
A PTO unit allows the transmission to power auxiliary equipment to run
devices such as snowplows, aerial lifts, tow truck lifts, cement mixers or
dump trucks.
Vehicles Equipped with an Allison Automatic Transmission (Except
3000 Series)
You can operate the PTO while your vehicle is standing or moving. To
engage the PTO, apply the brakes and shift to any gear other than
positionN,then engage the PTO.
If the gear teeth not meshing properly prevent engagement, release the
brakes and allow your vehicle to creep slightly or shift the selector to
positionNand then back into gear. Never engage the PTO by clashing

A qualified service technician should perform air brake inspection and
adjustment or repairs keeping to the instructions in the service manual.
Cam Brakes - Automatic Slack Adjusters
WARNING:Do not manually adjust the automatic slack adjusters
to correct excessive push rod stroke as it may result in reduced
brake effectiveness and a vehicle crash. Excessive push rod stroke
indicates that a problem exists with the automatic adjuster, with the
installation of the adjuster, or with foundation brake components that
manual adjustment does not remedy. Seek service from a qualified
facility for excessive push rod stroke.
Standard air brakes (cam) are
equipped with automatic brake
adjusters. Automatic adjustment
occurs during brake applications.
Inspect brakes for proper
adjustment at the intervals listed in
theScheduled Maintenance
chapter.
Emergency Air Brake
WARNING:Do not continue to operate the vehicle with a failure
of one of the brake systems. Take the vehicle to your dealer for
service immediately.
All vehicles are equipped with a dual brake system. In the unlikely event
of a failure of one system, the second system functions for emergency
stopping. The brake pedal controls all these systems in the same manner
as for normal stops.
