Typical Diesel Exhaust Fluid Usage
When Using the Power Take Off (PTO)
Continuous PTO use—Minimal PTO use
0–7,800 mi (0– 12,550 km)
Contaminated Diesel Exhaust
Fluid or Inoperative Selective
Catalytic Reduction System
Selective catalytic reduction systems are
sensitive to contamination of the diesel
exhaust fluid. Maintaining the purity of the
fluid is important to avoid system
malfunctions. If you remove or drain the
diesel exhaust fluid tank, do not use the
same fluid to refill the tank. The system
has a sensor to monitor fluid quality. A warning lamp illuminates and
a message appears in the
information display if the system
becomes contaminated or inoperative.
Continued driving without replacing diesel
exhaust fluid or having the selective
catalytic reduction system repaired results
in the following actions as required by the
California Air Resources Board (CARB) and
U.S. Environmental Protection Agency
(EPA):
• Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.
• Further vehicle operation without
replacing contaminated diesel exhaust
fluid causes the engine to enter an
idle-only condition. This only occurs
upon vehicle refueling, vehicle idling in
park for 1 hour, or engine shutdown for
10 minutes or more and is indicated by
a message in the information display
indicating required actions to resume
normal operation. Note:
For vehicle speed limiting or idle-only
condition, normal vehicle operation resumes
when you repair the contaminated system.
To service a contaminated or inoperative
system, see an authorized dealer.
DIESEL PARTICULATE FILTER
Your vehicle has a diesel particulate filter.
The diesel particulate filter is an inline filter
in the exhaust system that reduces carbon
emissions by trapping exhaust particles
before they reach the tailpipe. The diesel
particulate filter looks similar to a
traditional exhaust catalyst, except larger,
and is part of the exhaust system under
your vehicle. The filter couples to a diesel
oxidation catalyst that reduces the amount
of harmful exhaust emitted from the
tailpipe. As soot gathers in the system, it
begins to restrict the filter. Periodically, you
need to clean the soot that gathers inside
the filter. You can clean the soot in two
different ways, passive regeneration and
active regeneration. Both methods occur
automatically and require no actions from
the driver. During either one of these
regeneration methods, you may notice a
change in exhaust tone. At certain times,
various messages related to the diesel
particulate filter appear in the information
displays.

Oxidation Catalytic Converter and
Diesel Particulate Filter System (If
Equipped) 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. Use special care when
working around the diesel oxidation
catalytic converter or the diesel particulate
filter. The diesel oxidation catalytic
converter and the diesel particulate filter
heat up to very high temperatures after
only a short period of engine operation and
remain hot after you switch the engine off. Diesel Particulate Filter Maintenance
You must properly maintain your vehicle's
diesel particulate filter in order for it to
function properly.
Do not disregard maintenance messages
that appear in the information display.
Failure to follow the instructions of an
information message may degrade vehicle
performance and could lead to engine
damage that may not be covered by the
vehicle Warranty.
Failure to perform active or operator
commanded regeneration when instructed
could result in a clogged diesel particulate
filter. If the diesel particulate filter fills
beyond the regeneration threshold, your
vehicle disables the ability for active and
operator commanded regeneration. This
could result in irreversible damage to the
diesel particulate filter requiring
replacement that may not be covered by
the vehicle Warranty. Passive Regeneration
In passive regeneration, the exhaust
system temperature and constituents
automatically clean the filter by oxidizing
the soot. Cleaning automatically occurs
during normal vehicle operating conditions
due to driving patterns.
Active Regeneration
Once the diesel particulate filter is full of
exhaust particles, the engine control
module commands the exhaust system to
clean the filter through active regeneration.
Active regeneration requires the engine
computer to raise the exhaust temperature
to eliminate the particles. During cleaning,
the particles convert to harmless gasses.
Once cleaned the diesel particulate filter
continues trapping exhaust particles.
The regeneration process operates more
efficiently when you drive your vehicle at
a constant speed above
30 mph
(48 km/h) and at a steady engine speed
for approximately 20 minutes. The
frequency and duration of regeneration
fluctuates by how you drive your vehicle,
outside air temperature and altitude. For
most driving, regeneration frequency varies
from 100–500 mi (160–805 km) between
occurrences and each occurrence lasts
9– 35 minutes. You can usually reduce the
duration of regeneration if you maintain a
constant speed above 30 mph (48 km/h).
When the engine control module detects
that the diesel particulate filter is nearly
full of particulates and you are not
operating your vehicle in a manner to allow
effective automatic regeneration,
messages appear in the information
display as a reminder for you to drive your
vehicle in order to clean the diesel
particulate filter. If you drive your vehicle
in a manner to allow effective automatic
regeneration, the information display
110
F650750 (TBC) , enUSA, Edition date: 201708, First Printing Engine Emission Control

shows a cleaning exhaust filter message,
which is the normal regeneration process.
You can also choose operator commanded
regeneration to clean the exhaust system
at this point. See Information Messages
(page 66).
If you are not able to drive in a manner that
allows effective automatic active
regeneration or you choose to perform
regeneration of the diesel particulate filter
while at idle, then operator commanded
regeneration would need to be performed.
Operator Commanded Regeneration
(If Equipped)
If your vehicle is operated with significant
stationary operation, low speed drive
cycles less than
25 mph (40 km/h), short
drive cycles, a drive time is less than 10 -
15 minutes or the vehicle does not fully
warm up, passive and active regeneration
may not sufficiently clean the diesel
particulate filter system. Operator
commanded regeneration allows you to
manually start regeneration of the diesel
particulate filter at idle to clean the filter
only when the diesel particulate filter is full
(100%). If you are not sure whether your
vehicle has this feature, contact an
authorized dealer.
When to Carry Out Operator Commanded
Regeneration
You can use the operator commanded
regeneration feature when a message
appears in the information display only.
When viewing the Exhaust Filter Status
message - Exhaust Filter XX% and the
diesel particulate filter message indicates
FULL, and you are not able to drive in a
manner that allows effective automatic
active regeneration, or if you choose to
manually start the regeneration of the
diesel particulate filter manually while the
vehicle is idle. See
Information
Messages (page 66). Operator Commanded Regeneration
Precautions and Safe Exhaust Position WARNINGS
Do not park or idle your vehicle over
dry leaves, dry grass or other
combustible materials. The
regeneration process creates very high
exhaust gas temperatures and the exhaust
will radiate a considerable amount of heat
during and after regeneration and after you
have switched the engine off. This is a
potential fire hazard. Stay clear of the exhaust tailpipe
during regeneration. Hot exhaust
gases can burn you badly.
Make sure that the louvers located at the
tip of the exhaust are clear of any
obstructions as they are used to introduce
fresh air into the tailpipe to cool the
exhaust gases as they leave the exhaust
system.
Before you start operator commanded
regeneration, do the following:
•
Shift into park (P) or if you have an
RNDM selector shift into neutral (N)
and apply the parking and or air 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.

How to Start Operator Commanded
Regeneration
WARNING
Stay clear of the exhaust tailpipe
during regeneration. Hot exhaust
gases can burn you badly.
Note:
You cannot use the operator
commanded 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.
Note: During the use of operator
commanded regeneration, you may observe
a light amount of white smoke. This is
normal. You may not be able to use
operator commanded
regeneration if the service engine
soon warning lamp appears in the
information display
Information Display Procedure
Start your vehicle engine and when it has
reached the normal operating temperature,
press the information display control
button on the steering wheel until Exhaust
Filter XX%/FULL is displays. Operator
commanded regeneration can only be
initiated when FULL See Information
Display Control (page 47). If a message
advising that the exhaust filter is full
appears in the information display, press
the down arrow button to set the display
to
Y. Answer yes to this prompt and then
follow the next prompts regarding exhaust
position required to initiate operator
commanded 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. If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning
appears in the information display only if
viewing the Exhaust Filter Status message.
See
Information Messages (page 66).
Answer yes to this prompt and then follow
the next prompts regarding exhaust
position required to initiate operator
commanded 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 operator commanded regeneration
starts, engine speed increases to
approximately 2000 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 operator
commanded 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
exhaust system has had sufficient time to
cool. Depending on the amount of soot
collected by the diesel particulate filter,
ambient temperature and altitude,
operator commanded regeneration lasts
approximately 30 minutes.

Operator Commanded Regeneration
with Automatic Regeneration Control
(If Equipped)
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. You can switch off automatic
regeneration until better driving conditions
are available, for example steady high
speed driving. You can then switch
automatic regeneration back on to clean
the diesel particulate filter.
Switching Automatic Regeneration
Control On and Off
To switch operator commanded
regeneration on and off, use the
information display control on the steering
wheel. See Information Display Control
(page
47). Scroll to the exhaust cleaning
message and then select Y or N to switch
it On or Off.
How to Interrupt or Cancel Operator
Commanded Regeneration
If you need to cancel the operator
commanded regeneration, pressing the
brake, accelerator or switching the engine
off stops the procedure. Depending on the
amount of time you allowed the operator
commanded regeneration to operate, soot
may not have had sufficient time to be fully
eliminated, but the exhaust system and
exhaust gas may still be hot. If you shut
your vehicle off during operator
commanded regeneration, you may notice
turbo flutter. This is a normal consequence
caused by shutting off a diesel engine
during boosted operation and is considered
normal. Filter Service and Maintenance
Over time, a slight amount of ash builds
up in the diesel particulate filter, which is
not removed during the regeneration
process. The filter may need to be replaced
with a new or remanufactured part at
approximately 250,000 mi (400,000 km).
Actual mileage varies depending on engine
and vehicle operating conditions.
If filter service is required, the
engine control system warning
lamp illuminates in the
information display. If there are any issues with the
diesel particulate filter system,
the engine control system
warning lamp and a service
engine soon warning lamp
illuminate to inform you that
your vehicle requires service. Have your
vehicle checked as soon as possible.
Resonator and Tailpipe Assembly
Maintenance
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.

In order to prevent the engine from running
at too low an RPM, which may cause it to
stall, SelectShift still automatically makes
some downshifts if it has determined that
you have not downshifted in time.
Although SelectShift makes some
downshifts for you, it still allows you to
downshift at any time as long as the
SelectShift determines that there is no
damage to the engine from over-revving.
SelectShift does not automatically upshift,
even if the engine is approaching the RPM
limit. You must shift manually by pressing
the + button.
Note: Engine damage may occur if you rev
the engine excessively and hold it without
shifting. Automatic Transmission Adaptive
Learning
This feature's design is to increase
durability and provide consistent shift feel
over the life of your vehicle. A new vehicle
or transmission may have firm shifts, soft
shifts or both. This operation is normal and
does not affect function or durability of the
transmission. Over time, the adaptive
learning process fully updates transmission
operation. Additionally, whenever you
disconnect the battery or install a new
battery, the system must relearn the
strategy.

9. Start your vehicle.
Perform Steps 4 through 8 in reverse order,
making sure to engage the hinge pivots
between the upper and lower halves of the
shroud. Keep slight pressure in the forward
direction as you rotate the halves together.
If Your Vehicle Gets Stuck In Mud
or Snow
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute or damage to the
transmission and tires may occur, or the
engine may overheat.
If your vehicle is stuck in mud or snow, you
may rock it out by shifting between forward
and reverse gears, stopping between shifts
in a steady pattern. Press lightly on the
accelerator in each gear.
POWER TAKE-OFF
Auxiliary equipment called power take-off,
or PTO, is often added to the engine or
transmission to operate utility equipment.
Examples include a wheel-lift for tow
trucks, cranes, tools for construction or tire
service and pumping fluids. PTO
applications draw auxiliary horsepower
from the powertrain, often while the vehicle is stationary or mobile. In the
stationary condition, there is limited
cooling air flow through the radiator and
around the vehicle that normally occurs
when a vehicle is moving. The aftermarket
PTO system installer, having the most
knowledge of the final application, is
responsible for determining whether
additional chassis heat protection or
powertrain cooling is required and alerting
the user to the safe and proper operation.
Your vehicle is approved for use as a
Stationary Mode, SplitShaft Mode or
Mobile Mode power source within the limits
and operating guidelines detailed in the
Ford Truck Body Builders Layout Book,
found at
www.fleet.ford.com/truckbbas.com and
through the Ford Truck Body Builders
Advisory Service. The transmission power
source modes are engine specific.

WARNING
Sudden accelerations on slippery
surfaces could cause the wheels to
spin, the vehicle to turn sideways on
a crowned road surface or in a turn,
possibly resulting in loss of vehicle control
and personal injury. Activating the Locking Differential
You can lock and unlock the differential
when your vehicle is moving at a constant
speed of less than 25 mph (40 km/h) and
while the wheels are not slipping. Do not
lock the differential when your vehicle is
traveling down steep grades and when
traction is minimal.
The differential lock and differential lock
light automatically disengage at speeds
above 25 mph (40 km/h). The differential
lock remains off until either you restart your
vehicle or you turn the differential lock
switch off then back on.
Servicing a Vehicle with a Locking
Differential
Turn the engine off and raise all drive
wheels of the locker differential axle in
order to prevent your vehicle from moving
when servicing the wheels, tires or brakes.
Axles equipped with a driver-controlled
differential deliver power to both wheels
even when only one wheel is on the ground. WARNING
Failure to raise all drive wheels with
this type of differential could cause
the vehicle to move unexpectedly,
resulting in property damage, personal
injury or death. 2-SPEED REAR AXLE
(If Equipped)
WARNING
Never shift a two-speed axle when
descending a steep grade as this
may cause loss of vehicle control and
result in personal injury. Note:
Do not shift between ranges when
the speed control is on.
A two-speed rear axle allows the driver to
select a low range for greater pulling power
and a high range for greater road speed
and fuel economy. You can also use these
ranges to provide extra steps between
transmission shifts when driving on steep
grades or fuel economy may be factors.
Axle Shifting Note:
Do not shift the axle to LOW when
your vehicle is moving. Use LOW when you
drive a fully loaded vehicle on a severe grade
or in congested traffic. Use HIGH for all
normal driving conditions with a lightly
loaded or partially loaded vehicle.
Note: The axle is set to HIGH by default.
To shift the axle between HIGH and LOW
with the vehicle stopped, place the
transmission in position N, then press and
hold the button for two seconds.
