of recreational flat towing by putting the
transfer case into neutral (N). See

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. WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough
terrain without getting stuck or damaging
underbody components. The differences
that make your vehicle so versatile also
make it handle differently than an ordinary
passenger car. Always maintain steering
wheel control, 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. Drive slower in strong crosswinds
which can affect the normal steering
characteristics of your vehicle. Be
extremely careful when driving on
pavement made slippery by loose sand,
water, gravel, snow or ice.
Note:
Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components.
FOUR-WHEEL DRIVE
LIMITATIONS
Operating Four-Wheel Drive with
a Spare or Mismatched Tires
(If
Equipped)
On four-wheel drive vehicles, the size of
the spare tire can affect the four-wheel
drive system. If there is a significant
difference between the size of the spare
tire and the remaining tires, you could have
limited four-wheel drive functionality.
When driving with the full-size dissimilar
spare wheel and tire assembly, we
recommend that you do not:
• Exceed
50 mph (80 km/h) with a
four-wheel drive mode turned on.
• Turn on a four-wheel drive mode
unless the vehicle is stationary.
• Use a four-wheel drive mode on dry
pavement.
Driving with the full-size dissimilar spare
wheel and tire assembly can limit
four-wheel drive functionality, especially
when driving in a mechanically locked
four-wheel drive mode. You can experience
the following:
292
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Four-Wheel Drive
(If Equipped)

To select a four-wheel drive mode, press
the four-wheel drive mode control button
of the desired mode. You can select
two-wheel drive high (2H), four-wheel
drive high (4H), or if your vehicle has
four-wheel drive auto (4A) at a stop or
while driving. Once the shift is complete,
the information display will then display
the selected four-wheel drive mode. While
shifts are in progress, the lights on the
four-wheel drive control switch can flash
and you could see messages in the
information display indicating that a shift
is in progress or to release the accelerator
pedal to improve shift performance.
Note:
Do not perform this operation if the
rear wheels are slipping or while applying
the accelerator pedal.
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. See Four-Wheel Drive –
Information Messages (page 299).
Shifting to or from Four-Wheel
Drive Low (4L)
To select or exit four-wheel drive low (4L):
1. Bring your vehicle to a speed of
3 mph
(5 km/h) or less.
2. Place the transmission in neutral (N)
3. Press the desired four-wheel drive button on the four-wheel drive mode
control switch.
The information display will display a
message indicating a four-wheel drive shift
is in progress. If any of the above shift
conditions are not present, the shift will
not occur and the information display will
display information guiding the driver
through the proper shifting procedures. If
there is a transfer case tooth blockage a
message will display 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.
See Four-Wheel Drive –
Information Messages (page 299).
FOUR-WHEEL DRIVE MODES
TWO-WHEEL DRIVE HIGH
Two-wheel drive high is for general
on-road driving. Power is sent to the rear
wheels only.
Note: Two-wheel drive high can turn on or
off based on Drive Mode selection See Drive
Mode Control
(page 371).
FOUR-WHEEL DRIVE AUTO
(If
Equipped)
Four-wheel drive auto provides
electronically controlled four-wheel drive
power to both the front and rear wheels,
as required, for increased traction in varying
on-road conditions. The four-wheel drive
auto tuning varies based on selected Drive
Mode.
See Selecting a Drive Mode (page
373).
Note: Four-wheel drive auto can turn on or
off automatically based on Drive Mode
selection.
See Selecting a Drive Mode
(page 373).
