Using the Electronic Shift on the
Fly 4WD system (If Equipped) 2H (4X2)
For general on-road driving. Sends power
to the rear wheels only and should be used
for street and highway driving. Provides
optimal smoothness and fuel economy at
high speeds. 4H (4X4 HIGH)
Provides mechanically locked four-wheel
drive power to both the front and rear
wheels for use in off-road or winter
conditions such as deep snow, sand or
mud. This mode is not for use on dry
pavement.
4L (4X4 LOW)
Provides mechanically locked four-wheel
drive power to both the front and rear
wheels for use on low traction surfaces,
but does so with additional gearing for
increased torque multiplication. Intended
only for off-road applications such as deep
sand, steep grades, or pulling heavy
objects. 4L (4X4 low) will not engage while
your vehicle is moving above
3 mph
(5 km/h); this is normal and should be no
reason for concern. Refer to Shifting to or
from 4L (4X4 low) for proper operation.
Shifting between system modes
Note: Momentarily releasing the accelerator
pedal when a shift in progress message
displays improves engagement or
disengagement performance.
Note: Do not perform this operation if the
rear wheels are slipping or when applying
the accelerator pedal.
Note: Some noise may be heard as the
system shifts or engages; this is normal.
Note: 4X4 high mode is not intended for
use on dry pavement.
You can move the control from 2H or 4H
at a stop or while driving. The information
display may display a message indicating
a 4X4 shift is in progress. Once the shift is
complete the message center will then
display the system mode selected.
Shifting to or from 4L (4X4 low)
Note: Some noise may be heard as the

STEERING
Hydraulic Power Steering
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.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201909, Second-Printing Driving Aids

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. Adaptive Steering
(If Equipped)
Note: The adaptive steering system has
diagnostic checks that continuously monitor
the system. If the system detects a fault, a
message displays in the information display.
If a red warning message displays, stop your
vehicle as soon as it is safe to do so. The
message may clear if the fault is no longer
present. If an adaptive steering system
warning message appears each time you
start your vehicle, have the system checked
as soon as possible.
The adaptive steering system continually
changes the steering ratio with changes to
vehicle speed, optimizing the steering
response in all conditions. The system also
changes when you switch on the
transmission tow/haul feature. When you
select the tow/haul button, the adaptive
steering system reduces vehicle sensitivity
to steering inputs at higher vehicle speeds,
while maintaining the ease of parking and
maneuverability at low speeds.
Note: The adaptive steering system is
designed with a locking device. With the
lock engaged, the adaptive steering system
remains mechanically locked at a fixed
steering ratio. You may also notice a click
when you switch the vehicle on or after you
switch it off, as the lock disengages or
engages.
Note: If your vehicle loses electrical power
or detects a fault when you are driving, the
system automatically shuts down and you
retain normal steering function with a fixed
steering ratio. During this time it is possible
that the steering wheel may not be straight
when the vehicle is driving straight ahead.
In addition, the driver may notice that the
steering wheel angle required to steer the
vehicle may be different.

•
Inspect exhaust system for damage or
looseness.
• Inspect undercarriage fasteners. If any
are loose or damaged, tighten or
replace ensuring that the proper torque
specification is used.
• Inspect the tires for any cuts in the
tread or sidewall area. Also inspect the
sidewall for any bulge indicating
damage to the tire.
• Inspect the wheels for dents, cracks,
or other damage.
• Refit the front license plate if removed
previously.
BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
Avoid driving too fast during the first
1,000 mi (1,600 km)
. Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Drive your new vehicle at least
1,000 mi
(1,600 km) before towing a trailer. Make
sure you use the specified engine oil. See
Capacities and Specifications
(page
441).
Do not add friction modifier compounds
or special break-in oils during the first few
thousand miles (kilometers) of operation.
These additives may prevent piston ring
seating.
DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle. Note:
Engine damage can occur if water
enters the air filter.
For Vehicles without Tremor Off-
Road Package
Note: Driving through standing water can
cause vehicle damage.
Note: Drive through water in an emergency
only and not as part of normal driving.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.

Remove the lug nuts with the lug wrench,
replace the flat tire with the spare, making
sure the valve stem of the spare is facing
outward when replacing a front wheel. For
the rear wheel position on vehicles with
single rear wheel fitments, install the spare
with the valve stem facing outward. For
vehicles with dual rear wheels, the valve
stem of the spare must face outward when
replacing an inner wheel, but must face
inward when replacing an outboard wheel.
Reinstall the lug nuts until the wheel is
snug against the hub. Do not fully tighten
the lug nuts until the wheel has been
lowered.
Lower the vehicle completely by turning
the jack handle counterclockwise until the
vehicle is completely lowered.
Note:
For F-350 Dual Rear Wheel, F-450
and F-550 Vehicles, insert the notched end
of the jack handle to the release valve, open
the release valve slightly by turning the
handle counterclockwise. Stop turning the
release valve when vehicle start to lower.
Make sure to close the valve when you
completely lower your vehicle.

2. Slide the wheel partially under the
vehicle and install the retainer through
the wheel center. If equipped, you may
have to remove the wheel center cap
prior to pushing the retainer through
the center of the wheel. To remove the
center cap, press it off with the lug
wrench tip from the inner side of the
wheel. Pull on the cable to align the
components at the end of the cable. 3.
Turn the lug wrench clockwise until the
tire is raised to its stowed position
underneath the vehicle. The wrench
will become harder to turn and the
spare tire winch will ratchet or slip
when the tire is raised to maximum
tightness. You will hear a clicking sound
from the winch indicating that the tire
is properly stowed. Check that the tire
lies flat against the frame and is
properly tightened.
4. Carefully place all tools back in the tool
kit bag.
5. Reinstall the tool kit bag and tighten the wing nut.
6. Properly reinstall the jack into the bracket and tighten the wing nut.
TECHNICAL SPECIFICATIONS
Wheel Lug Nut Torque Specifications WARNING: When you install a wheel, always remove any corrosion, dirt or foreign
materials present on the mounting surfaces of the wheel or the surface of the wheel
hub, brake drum or brake disc that contacts the wheel. Make sure to secure any fasteners
that attach the rotor to the hub so they do not interfere with the mounting surfaces of
the wheel. Installing wheels without correct metal-to-metal contact at the wheel
mounting surfaces can cause the wheel nuts to loosen and the wheel to come off while
your vehicle is in motion, resulting in loss of vehicle control, personal injury or death. lb.ft (Nm)
