If the diesel particulate filter is near or at
saturation, a message requesting
permission to initiate filter cleaning
appears in the information display. See
Information Messages (page 131).
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
85). Scroll to the exhaust cleaning
message, a check in the box indicates the
feature is enabled, and unchecked
indicates the feature is disabled.
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.

First (1)
•
Transmission operates in first (1) gear
only.
• Provides maximum engine braking.
• Allows upshifts by moving gearshift
lever.
• Does not downshift into first (1) gear
at high speeds; allows for first (1) gear
when vehicle reaches slower speeds.
Forced downshifts
• Allowed in drive (D) with the tow/haul
feature on or off.
• Press the accelerator to the floor.
• Allows transmission to select an
appropriate gear.
Tow/Haul Mode WARNING
Do not use tow/haul when the road
surface is slippery. Failure to follow
this instruction could result in the
loss of control of your vehicle. To activate tow/haul, press the
button on the gearshift lever
once. The TOW HAUL indicator
light illuminates in the instrument cluster. The tow/haul feature:
•
Delays upshifts to reduce the frequency
of transmission shifting.
• Provides engine braking in all forward
gears, which slows your vehicle and
assists you in controlling your vehicle
when descending a grade.
• Depending on driving conditions and
load conditions, may downshift the
transmission, slow your vehicle and
control your vehicle speed when
descending a hill, without pressing the
accelerator pedal. The amount of
downshift braking provided varies
based upon the amount you press the
brake pedal.
The tow/haul feature improves
transmission operation when towing a
trailer or a heavy load. All transmission
gear ranges are available when using
tow/haul.
Note: If your vehicle is equipped with the
Adaptive Steering System, enabling the
tow/haul feature adjusts the steering
response. In tow/haul mode the Adaptive
Steering system reduces vehicle sensitivity
to steering inputs at higher vehicle speeds
when maintaining the ease of parking and
maneuverability at low speeds. See
Steering (page 261).
To deactivate the tow/haul feature and
return to normal driving mode, press the
button on the gearshift lever when
tow/haul is active. The TOW HAUL light
deactivates. Tow/haul also deactivates
when you power down your vehicle.

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.
Brake-Shift Interlock WARNINGS
When doing this procedure, you need
to take the transmission out of park
(P) which means your vehicle can
roll freely. To avoid unwanted vehicle
movement, always fully apply the parking
brake prior to doing this procedure. Use
wheels chocks if appropriate. If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. Have your vehicle
checked as soon as possible. Note:
Do not drive your vehicle until you
verify that the brake lamps are working.
Your vehicle is equipped with a brake-shift
interlock feature that prevents the
gearshift lever from moving from park (P)
when the ignition is on and the brake pedal
is not pressed.
If you cannot move the gearshift lever out
of park (P) position with the ignition is on
and the brake pedal pressed, a malfunction
may have occurred. It is possible that a
fuse has blown or your vehicle ’s brake
lamps are not operating properly. See
Fuse Specification Chart (page 318).
If the fuse is not blown and the brake
lamps are working properly, the following
procedure allows you to move the gearshift
lever from park (P):
1. Apply the parking brake. Switch the ignition key to 1 (off), then remove the
key.
2. Move the steering column to the full down and full rearward position
(toward the driver ’s seat).
3. Remove the gearshift lever boot.

If Shift Delayed Pull Forward appears in
the information display, transfer case gear
tooth blockage is present. To alleviate this
condition, place the transmission in a
forward gear, move the vehicle forward
approximately
5 ft (1.5 m), and shift the
transmission back to neutral to allow the
transfer case to complete the range shift.
How Your Vehicle Differs From
Other Vehicles WARNING
Vehicles with a higher center of
gravity (utility and four-wheel drive
vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury and
death. Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough
terrain without getting hung up or
damaging underbody components.
The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
Maintain steering wheel control at all
times, especially in rough terrain. Since
sudden changes in terrain can result in
abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps. You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the
area. To maintain steering and braking
control of your vehicle, you must have all
four wheels on the ground and they must
be rolling, not sliding or spinning.
Driving Off-Road With Truck and
Utility Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive while
the vehicle is moving can cause some
momentary clunk and ratcheting sounds.
This is the front drivetrain coming up to
speed and the automatic locking hubs
engaging and is not cause for concern.
Note: Your vehicle may be equipped with
a front air dam that can become damaged
(due to reduced ground clearance) when
taking your vehicle off-road. This air dam
can be taken off by removing 15 bolts.
Four-wheel drive vehicles are specially
equipped for driving on sand, snow, mud
and rough terrain and have operating
characteristics that are somewhat
different from conventional vehicles, both
on and off the road.
Power is supplied to all four wheels
through a transfer case. On four-wheel
drive vehicles, the transfer case allows you
to select 4WD when necessary.
Information on transfer case operation and
shifting procedures can be found in this
chapter. Information on transfer case
maintenance can be found in the
Maintenance chapter. You should become
thoroughly familiar with this information
before you operate your vehicle.
Four-wheel drive (when you select a 4WD
mode) uses all four wheels to power the
vehicle. This increases traction, enabling
you to drive over terrain and road
conditions that a conventional two-wheel
drive vehicle cannot.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, First Printing Four-Wheel Drive
(If Equipped)
Basic Operating Principles
•
Drive slower in strong crosswinds which
can affect the normal steering
characteristics of your vehicle.
• When driving your vehicle on surfaces
made slippery by loose sand, water,
gravel, snow or ice proceed with care.
• Do not use 4H or 4L on dry, hard
surfaced roads. Doing so will produce
excessive noise, increase tire wear and
may damage drive components. 4H or
4L modes are only intended for
consistently slippery or loose surfaces.
If Your Vehicle leaves the Road
If your vehicle leaves the road, reduce your
vehicle speed and avoid severe braking.
When your vehicle speed has been reduced
ease your vehicle back onto the road. Do
not turn the steering wheel sharply while
returning your vehicle to the road.
It may be safer to stay on the shoulder of
the road and slow down gradually before
returning to the road. You may lose control
if you do not slow down or if you turn the
steering wheel too sharply or abruptly.
It may be less risky to strike small objects,
such as freeway reflectors, with minor
damage to your vehicle rather than
attempt a sudden return to the road which
could cause your vehicle to slide sideways
out of control or roll over. Remember, your
safety and the safety of others should be
your primary concern.
Emergency Maneuvers
In an unavoidable emergency situation
where a sudden sharp turn must be made,
remember to avoid over-driving your
vehicle (i.e. turn the steering wheel only as
rapidly and as far as required to avoid the
emergency). Excessive steering can result
in loss of vehicle control. Apply smooth
pressure to the accelerator pedal or brake
pedal when changes in vehicle speed are required. Avoid abrupt steering,
acceleration and braking. This could result
in an increased risk of vehicle roll over, loss
of vehicle control and personal injury. Use
all available road surface to bring your
vehicle to a safe direction of travel.
In the event of an emergency stop, avoid
skidding the tires and do not attempt any
sharp steering wheel movements.
If your vehicle goes from one type of
surface to another (i.e. from concrete to
gravel) there will be a change in the way
your vehicle responds to a maneuver (i.e.
steering, acceleration or braking).
Sand
When driving over sand, try to keep all four
wheels on the most solid area of the trail.
Avoid reducing the tire pressures but shift
to a lower gear and drive steadily through
the terrain. Apply the accelerator slowly
and avoid excessive wheel slip.
When driving at slow speeds in deep sand
under high outside temperatures, use a low
gear when possible. Low gear operation
will maximize the engine and transmission
cooling capability.
Avoid driving at excessive speeds, this
causes vehicle momentum to work against
you and your vehicle could become stuck
to the point that assistance may be
required from another vehicle. Remember,
you may be able to back out the way you
came if you proceed with caution.
Mud and Water
Mud
Be cautious of sudden changes in vehicle
speed or direction when you are driving in
mud. Even four-wheel drive vehicles can
lose traction in slick mud. If your vehicle
does slide, steer in the direction of the slide
until you regain control of your vehicle.
221
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, First Printing Four-Wheel Drive (If Equipped)
Driving on Snow and Ice
WARNING
If you are driving in slippery
conditions that require tire chains or
cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end of
your vehicle slides while cornering, steer in
the direction of the slide until you regain
control of your vehicle. Note:
Excessive tire slippage can cause
transmission damage.
Four-wheel drive vehicles have advantages
over two-wheel drive vehicles in snow and
ice but can skid like any other vehicle.
Should you start to slide while driving on
snowy or icy roads, turn the steering wheel
in the direction of the slide until you regain
control.
Avoid sudden applications of power and
quick changes of direction on snow and
ice. Apply the accelerator slowly and
steadily when starting from a full stop.
Avoid sudden braking. Although a
four-wheel drive vehicle may accelerate
better than a two-wheel drive vehicle in
snow and ice, it will not stop any faster as
braking occurs at all four wheels. Do not
become overconfident as to road
conditions.
Make sure you allow sufficient distance
between you and other vehicles for
stopping. Drive slower than usual and
consider using one of the lower gears. In
emergency stopping situations, apply the
brake steadily. Do not pump the brake
pedal. See Hints on Driving With
Anti-Lock Brakes (page 229). If Your Vehicle Gets Stuck In Mud or
Snow WARNING
Do not spin the wheels at over
34 mph (55 km/h). The tires may fail
and injure a passenger or bystander.
If your vehicle gets stuck in mud or snow,
it may be rocked out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature,
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute, damage to the transmission
and tires may occur or the engine may
overheat.
Parking WARNINGS
If the parking brake is fully released,
but the brake warning lamp remains
illuminated, the brakes may not be
working properly. Have your vehicle
checked as soon as possible. Always set the parking brake and
leave your vehicle with the
transmission in park (P).
On some four-wheel drive vehicles, when
the transfer case is in the N (Neutral)
position, the engine and transmission are
disconnected from the rest of the driveline.
Therefore, the vehicle is free to roll even if
the automatic transmission is in P (Park)
or the manual transmission is in gear. Do
not leave the vehicle unattended with the
transfer case in the N (Neutral) position.
Always set the parking brake fully and turn
off the ignition when leaving the vehicle.

Maintenance and Modifications
The suspension and steering systems on
your vehicle have been designed and
tested to provide predictable performance
whether loaded or empty. For this reason,
we strongly recommend that you do not
make modifications such as adding or
removing parts (i.e. lift kits or stabilizer
bars) or by using replacement parts not
equivalent to the original factory
equipment.
We recommend that you use caution when
your vehicle has either a high load or device
(i.e. ladder or luggage racks). Any
modifications to your vehicle that raise the
center of gravity may cause your vehicle
to roll over when there is a loss of vehicle
control.
Failure to maintain your vehicle correctly
may void the warranty, increase your repair
cost, reduce vehicle performance and
operational capabilities and adversely
affect you and your passenger's safety. We
recommend you frequently inspect your
vehicle's chassis components when your
vehicle is subject to off road usage.

LIMITED SLIP DIFFERENTIAL
This axle provides added traction on
slippery surfaces, particularly when one
wheel is on a poor traction surface. Under
normal conditions, the limited-slip axle
functions like a standard rear axle. The axle
may exhibit a slight noise or vibration
during tight turns with low vehicle speed.
This is normal behavior and indicates the
axle is working.
ELECTRONIC LOCKING
DIFFERENTIAL (If Equipped)
Note: The electronic locking differential is
for off-road use only and is not for use on
dry pavement. Using the electronic locking
differential on dry pavement will result in
increased tire wear, noise and vibration.
The electronic locking differential is a
device housed in the rear axle that allows
both rear wheels to turn at the same
speed. The electronic locking differential
can provide additional traction should your
vehicle become stuck. You can activate
the differential electronically and shift it
on the fly within the differential operating
speed range. The differential is for use in
mud, rocks, sand, or any off-road condition
where you need maximum traction. It is
not for use on dry pavement.
The following conditions will affect the
electronic locking differential:
• The electronic locking differential will
not engage if your vehicle speed is
above
20 mph (32 km/h) in 4x2 or 4x4
High modes.
• The electronic locking differential will
not engage if your vehicle speed is
above or
56 mph (90 km/h) in 4X4
Low. •
The electronic locking differential may
not engage if you press your
accelerator pedal during an
engagement attempt. A message may
display in the instrument display
guiding you to release the accelerator
pedal.
• In 4x2 or 4x4 High modes, the
electronic locking differential will
automatically disengage at speeds
above
25 mph (41 km/h) and will
automatically reengage at speeds
below
20 mph (32 km/h).
• In 4L (4X4 low), the electronic locking
differential will automatically
disengage at speeds above
62 mph
(100 km/h) and will automatically
reengage at speeds below 56 mph
(90 km/h).
• The AdvanceTrac system has the
ability to take over control of the
electronic locking differential and
disable it during driving maneuvers
when necessary.
When you switch the system on, if you do
not meet the required conditions for
electronic locking differential activation,
the instrument cluster will display the
appropriate information guiding you
through the proper activation process.
Activating the Electronic Locking
Differential
Note: Do not use electronic locking
differential on dry, hard surfaced roads.
Doing so will produce excessive noise,
vibration and increase tire wear.
Note: If the electronic locking differential
has difficulty disengaging, release the
accelerator pedal and turn the steering
wheel in the opposite direction while rolling.
