HOW DOES FOUR-WHEEL
DRIVE WORK
Using the Electronic Shift On the
Fly System (If Equipped)
This four-wheel drive system utilizes a
2-speed Electronic Shift On the Fly (ESOF)
transfer case which is also known as a
part-time system. This system offers the
driver two-wheel drive high, four-wheel
drive high, and four-wheel drive low as
available modes of operation. When you
select either four-wheel drive high or
four-wheel drive low, the system provides
mechanically locked four-wheel drive
power to both the front and rear wheels
for use in off-road or slippery conditions
such as deep snow, sand or mud. When
you select four-wheel drive low, the system
provides additional gearing for increased
torque multiplication for conditions like
deep sand, steep slopes, or pulling heavy
objects. Additionally, the system is capable
of recreational flat towing by putting the
transfer case into a neutral position. See
Recreationally Towing Your Vehicle
(page
384). For proper operation, make sure that each
hub is fully engaged and that both hub
locks are set to the same position (both
set to lock or both set to auto). To engage
lock, turn the hub locks completely
clockwise. To engage auto, turn the hub
locks completely counterclockwise.
The ESOF four-wheel drive system:
•
Provides 4x4 High engagement and
disengagement while the vehicle is
moving.
• Operates by a rotary control located
on the instrument panel that allows
you select 4x2, 4x4 High or 4x4 Low
operation.
• Uses auto-manual hub locks that can
be engaged and disengaged
automatically based on the 4x4 mode
you select.
• Increases fuel economy when used in
the hub lock's recommended auto
mode.
Note: Auto-manual hub locks manually
lock by rotating the hub lock control from
auto to lock.
FOUR-WHEEL DRIVE
PRECAUTIONS 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.

(5 km/h) or less.
2. Place the transmission in neutral (N).
3. Move the four-wheel drive control to the preferred position.
The information display then displays a
message indicating a four-wheel drive shift
is in progress. If any of the above shift
conditions are not present, the shift wont
occur and the information display shows
information guiding the driver through the
proper shifting procedures. If there is a
transfer case tooth blockage Shift Delayed
Pull Forward displays in the information
display. To alleviate this condition, place
the transmission in a forward gear, move
your vehicle forward approximately
5 ft
(1.5 m), and shift the transmission back to
neutral (N) to allow the transfer case to
complete the range shift.
Note: You could hear some noise as the
system shifts or engages which is normal.
If the system detects a fault, a warning
message appears in the information
display.

WHAT IS HILL START ASSIST
Hill Start Assist makes it easier for you to
pull away when your vehicle is on a slope
without using the parking brake.
HOW DOES HILL START
ASSIST WORK
When the system activates, your vehicle
remains stationary for a few seconds after
you release the brake pedal. This gives you
time to move your foot from the brake
pedal to the accelerator pedal. The brakes
release when the engine has developed
sufficient torque to prevent your vehicle
from rolling down the slope.
HILL START ASSIST
PRECAUTIONS
WARNING: The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake. WARNING:
You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system turns off if
there is a malfunction or if you
excessively rev the engine. HILL START ASSIST –

Side Wind Stabilization
Side wind stabilization is an advanced
feature that works by carefully applying
the brakes on one side of the vehicle to
reduce the effect of a side wind gust on
the vehicle's path.
Torque Vectoring by Brakes
Torque vectoring control applies brake
torque on the inner driven wheel in a curve
for better traction to avoid an understeer,
or oversteer situation. Unlike electronic
stability control, enhanced torque
vectoring control does not slow the
vehicle. It helps control excessive wheel
slip and gives the vehicle improved
cornering agility.
Traction Control
Traction control enhances your vehicle
’s
ability to maintain traction of the wheels
by detecting and controlling wheel spin.

HYDRAULIC POWER
STEERING
HYDRAULIC POWER STEERING
GUIDELINES
To help prevent damage to the power
steering system:
•
Do not hold the steering wheel at its
furthest turning points for more than
three to five seconds when the engine
is running.
• Avoid continuously steering back and
forth with elevated engine RPM as this
may overheat the system. If trying to
free a stuck vehicle, pause between
attempts to allow the power steering
system to cool or seek assistance.
Typical steering and driving maneuvers
allow the system to cool.
• Do not operate the vehicle if the power
steering pump fluid level is below the
MIN mark on the reservoir.
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
If the power steering system breaks down
or if you switch the engine off, you can
steer the vehicle manually, but it takes
more effort. If you have any steering components
serviced or replaced, install new fasteners.
Many fasteners have coatings with thread
adhesive, or have prevailing torque
features you cannot reuse. Do not reuse a
bolt or nut. Torque fasteners to
specifications.
Steering Tips
If the steering wanders or pulls, check for:
•
An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull.
Electronic Torque Overlay Steering
(If Equipped) WARNING: The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.
256
2022 Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202103, First-Printing Steering
The electronic torque overlay steering
system adds supplemental steering assist
to the hydraulic gear when needed,
dependent on vehicle conditions such as
vehicle speed, steering wheel angle, and
steering wheel torque. The hydraulic
steering system provides the majority of
steering assistance. The electronic torque
overlay enables features such as pro trailer
backup assistance and lane departure
warning.
If your vehicle loses electrical power while
you are driving, your vehicle loses electric
power steering assistance. The steering
system still operates, and you can steer
your vehicle with hydraulic assist. Steering
your vehicle with only hydraulic assist
requires more effort.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Adaptive Learning (If Equipped)
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Whenever the battery
is disconnected or a new battery installed,
you must drive your vehicle a short
distance before the system relearns the
strategy and reactivates all systems. LOCATING THE HYDRAULIC
POWER STEERING FLUID
RESERVOIR
The hydraulic power steering fluid reservoir
is found in the engine compartment.
See
Under Hood Overview (page 397).
CHECKING THE HYDRAULIC
POWER STEERING FLUID
Check the power steering fluid. See
Scheduled Maintenance
(page 622). If
adding fluid is necessary, use only
MERCON LV ATF.
Check the fluid level when it is at ambient
temperature.
1. Check the fluid level in the reservoir. It should be between the MIN and MAX
range. Do not add fluid if the level is
within this range.
2. If the fluid level is low, add fluid to bring
the fluid level up to between the MIN
and MAX range.
3. Switch the engine on.
4. While the engine idles, turn the steering
wheel left and right several times.
5. Switch the engine off.
6. Recheck the fluid level in the reservoir. Do not add fluid if the level is between
the MIN and MAX range.
7. If the fluid is low, add fluid in small amounts, continuously checking the
level until it is between the MIN and
MAX range. For proper fluid type, See
Capacities and Specifications (page
467
). Be sure to put the cap back on the
reservoir.

HOW DOES TRAILER SWAY
CONTROL WORK
The system applies the brakes to the
individual wheels and reduces engine
torque to aid vehicle stability.
If the trailer begins to sway, the stability
control lamp flashes and the message
Trailer Sway Reduce Speed appears in
the information display.
Stop your vehicle as soon as it is safe to
do so. Check the vertical weight on the
tow ball and trailer load distribution.
TRAILER SWAY CONTROL
PRECAUTIONS WARNING: Turning off trailer sway
control increases the risk of loss of
vehicle control, serious injury or death.
Ford does not recommend disabling this
feature except in situations where speed
reduction may be detrimental (such as
hill climbing), the driver has significant
trailer towing experience, and can control
trailer sway and maintain safe operation.
Note: This feature only activates when
significant trailer sway occurs.
Note: This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if vehicle speed is too
high, the system may activate multiple
times, gradually reducing vehicle speed.
SWITCHING TRAILER SWAY
CONTROL ON AND OFF
1. Press
Features on the touchscreen. 2. Press
