Instrument cluster lamp(s) illuminates or flashes when operator
assistance is required. In addition, engine performance becomes
increasingly limited above Level 1.
At Levels 1 and 2, the operator can take two courses of action to
facilitate filter regeneration:
1. Drive your vehicle on the highway at highway speeds.
2. Perform a parked regeneration by following the steps inParked
regeneration.
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
WARNING:When performing the parked regeneration
procedure, make certain the vehicle is safely off the 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 your 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. Ford recommends that you perform a
walk-around before beginning a parked regeneration.
2. If your vehicle is equipped with an automatic transmission and a
steering column shift lever, place the transmission in positionP.
Otherwise, place the transmission in positionN.
3. Remove your feet from the accelerator pedal and clutch pedal
(manual transmission).
4. Set the parking brake.
5. Within five seconds of setting the parking brake, remove your 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 positionPorNas previously
described in Step 2.

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.

Brake-shift Interlock
Vehicles equipped with a gasoline engine have a brake-shift interlock
feature that prevents you from moving the gearshift lever from position
Pwhen the ignition is in the on position and the brake pedal is not
pressed.
If you cannot move the gearshift lever out of positionPwith the ignition
in the on position and the brake pedal pressed, it is possible that a fuse
has blown or your vehicle’s brake lamps are not operating properly. See
theFuseschapter.
WARNING:Do not drive your vehicle until you verify that the
brake lamps are working.
WARNING:When doing this procedure, you will be taking the
vehicle out of park which means the vehicle can roll freely. To
avoid unwanted vehicle movement, always fully set the parking brake
prior to doing this procedure. Use wheel chocks if appropriate.
WARNING:If the parking brake is fully released, but the brake
warning lamp remains illuminated, the brakes may not be
working properly. See your authorized dealer.

Position 1
•Provides maximum engine braking.
•Allows upshifts by moving gearshift lever.
•The transmission does not downshift into position1at high speeds; it
downshifts to a lower gear and then shifts into position1when your
vehicle reaches slower speeds.
Forced Downshifts
•Allowed in positionD.
•Press the accelerator to the floor.
•Allows transmission to select an appropriate gear.
Allison 2200 with Parking Pawl Feature
Note:Also, see the separateAllison Transmission Operator’s Manual.
WARNING:Always set the parking brake fully. Do not use the
gearshift in place of the parking brake.
WARNING: To avoid sudden, unexpected vehicle movement
and possible personal injury or death:
1. Bring the vehicle to a complete stop.
2. Shift the transmission into positionP.Slowly lift your foot from the
brake pedal to engage the transmission parking pawl mechanism.
3. Apply the parking brake and make sure it is holding properly. Do not
rely solely on the parking mechanism of the transmission.
4. Turn the engine off when you leave the vehicle.Never leave the
vehicle unattended when the engine is running.
A parking pawl effectively grounds the transmission’s output shaft
preventing rotation of the driveline. If your vehicle is stationary, selecting
positionPplaces the transmission in neutral and engages the parking
pawl. Always use the parking brake when parking your vehicle.
Note:If you select positionPwhen your vehicle is moving, the parking
pawl mechanism ratchets and does not hold the truck.

Allison 3000
Note:For more information about this transmission, see the separate
Allison 3000 Series Operator’s Manual.
The Allison 3000 series offers two shift modes: Performance and
Economy.
Performance mode gives the best all-around transmission operation. The
transmission defaults to this mode when you start the engine. Pressing
MODE on the shifter switches to Economy mode and illuminates the
Mode ON lamp.
Economy mode provides operation at lower engine RPM while
maintaining adequate performance.
If the engine speed is above idle when a gear is selected using the
shifter, the vehicle does not move; the shifter must be moved to re-select
a gear after the engine speed returns to idle.
Torque Lock
If you park your vehicle on an incline without properly engaging position
P(by shifting into positionPbefore applying the parking brake), the
weight of the vehicle may generate an excessive amount of torque on the
parking pawl. This makes it difficult to shift the transmission out of
positionP.Hold the brake pedal down while shifting out of positionP,
then release the parking brake.

the gear teeth. This may damage the PTO unit and the transmission PTO
drive gear teeth, resulting in further damage to the transmission and
PTO.
PTO Operation with Vehicle Stationary
WARNING:When the PTO is operated with the vehicle
stationary, the transmission must be placed in positionNwith the
parking brake set. If the transmission is not in positionNand is
equipped with a remote throttle control, an increase in engine speed
can overpower the parking brake and cause the vehicle to move,
possibly resulting in personal injury and/or property damage.
Stop your vehicle, idle the engine and set the parking brake. Make sure
the gear selector is in any forward drive range, and then engage the
PTO. After engaging the PTO, move the range selector to positionN.
Increase the engine speed until reaching the desired PTO operation
speed. To disengage the PTO after operation with your vehicle standing,
release the throttle, allow the drive equipment to come to a stop, and
then disengage the PTO.
PTO Operation while Vehicle Is Moving
After engaging the PTO for driven vehicle operation, shift to the desired
range and drive your vehicle. The speed of the PTO, during this period
of operation, always maintains direct relation to vehicle speed. PTO
speed decreases in relation to vehicle (transmission output) speed as
shifts to a higher gear occur. When operating the PTO while your vehicle
is moving, the PTO may be disengaged whenever it is no longer required.
When there is no load on the PTO gear, you can pull it out of
engagement.
Vehicles Equipped with an Allison 3000 Series Automatic
Transmission
The PTO drive gear is engine-driven and provides direct engine power.
You can operate the PTO when your vehicle is either stationary or
moving. The PTO gear is in constant mesh with the drive gear in the
torque converter housing. A friction clutch or constant drive transmits
power to the PTO.
Vehicles Equipped with a Manual Transmission
Transmission-mounted PTO units are available for local installation on
your vehicle. See yourBody Builder’s Layout Bookfor restrictions on
use and installation of PTO units.
