Operating 4WD vehicles with spare or
mismatched tires
On four-wheel drive vehicles, the size of
the spare tire can affect the 4X4 system.
If there is a significant difference between
the size of the spare tire and the remaining
tires, you may have limited four-wheel
drive functionality.
When driving with the full-size dissimilar
spare wheel and tire assembly, it is
recommended that you do not:
• Exceed
50 mph (80 km/h) with a 4WD
mode turned on.
• Turn on a 4WD mode unless the
vehicle is stationary.
• Use a 4WD mode on dry pavement.
When driving with the full-size dissimilar
spare wheel and tire assembly, 4WD
functionality may be limited, especially
when driving in a mechanically locked 4WD
mode. You may experience the following:
• Additional noise from the transfer case
or other drive components.
• Difficulty shifting out of a mechanically
locked 4WD mode. Use of a dissimilar spare wheel and tire
assembly may lead to impairment of the
following:
•
Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.
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.
216
F-150 (TFC) Canada/United States of America, enUSA, Edition date: 201709, Fifth-Printing Four-Wheel Drive
(If Equipped)

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
your 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 have a front air
dam. Due to low ground clearance, you can
damage it when taking your vehicle off-road.
You can take the air dam off by removing
the bolts that secure it.
Note: Your vehicle may have an underbody
transmission shield and brackets. Due to
low ground clearance, you can damage
them when taking your vehicle off-road.
Remove the shield by disengaging the
fasteners at each corner of the shield. Then,
remove the shield's rear brackets by
removing the bracket to frame 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. The transfer case supplies power to all four
wheels. On four-wheel drive vehicles, the
transfer case allows you to select different
4WD modes when necessary. You can find
information on transfer case operation and
shifting procedures in this chapter. You can
find information on transfer case
maintenance 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 your
vehicle. This increases traction, enabling
you to drive over terrain and road
conditions that a conventional two-wheel
drive vehicle cannot.
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 can produce
excessive noise, increase tire wear and
may damage drive components. 4H or
4L modes are only 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 decreases, 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.

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, 4x4
Auto, 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, 4x4 Auto, and 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.
For 4WD vehicles Pull the 4WD control knob toward you.

Engine Temperature while Plowing
Your engine may run at a higher
temperature than normal because the
attached snowplow blade restricts airflow
to the radiator:
•
If you are driving more than 15 mi
(24 km) at temperatures above
freezing, angle the plow blade either
full left or full right to provide
maximum airflow to the radiator.
• If you are driving less than
15 mi
(24 km) at speeds up to 45 mph
(72 km/h) in cold weather, you do not
need to worry about blade position to
provide maximum airflow.
Transmission Operation while
Plowing WARNING: Do not spin the wheels
at over
34 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
• Shift transfer case to
4L (4WD Low)
when plowing in small areas at speeds
below
5 mph (8 km/h).
• Shift transfer case to
4H (4WD High)
when plowing larger areas or light snow
at higher speeds. Do not exceed 15 mph
(24 km/h)
.
• Do not shift the transmission from a
forward gear to
R (Reverse) until the
engine is at idle and the wheels have
stopped.
Outside Air Temperature While
Plowing
While plowing with your vehicle, the plow
blade can block the sensor airflow and
cause the outside air temperature reading
to be inaccurate. A Ford wiring kit is available to relocate the
Outside Air Temperature sensor to the
plow blade frame to provide more
accurate outside air temperature readings.
Contact an authorized dealer for more
information.

Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
If you have a dissimilar spare wheel and
tire, then it is intended for temporary use
only. This means that if you need to use it,
you should replace it as soon as possible
with a road wheel and tire assembly that
is the same size and type as the road tires
and wheels that were originally provided
by Ford.
A dissimilar spare wheel and tire assembly
is defined as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and
wheels.
Full-size dissimilar spare
When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
• Exceed
70 mph (113 km/h).
• Use more than one dissimilar spare
wheel and tire assembly at a time.
• Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly.
When driving with the full-size dissimilar
spare wheel and tire assembly, 4WD
functionality may be limited, especially
when driving in a mechanically locked 4WD
mode. You may experience the following:
• Additional noise from the transfer case
or other drive components.
• Difficulty shifting out of a mechanically
locked 4WD mode.
