HOW DOES AUTO HOLD WORK
Auto Hold applies the brakes to hold your
vehicle after you stop it and release the
brake pedal. This can help when waiting
on a hill or in traffic.
SWITCHING AUTO HOLD ON
AND OFF
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.
You can switch the system on or off by
accessing the menu in the SYNC display
screen.
1. Press
Features on the touchscreen.
2. Press
Driver Assistance.

WHAT IS TRAIL TURN ASSIST
Trail turn assist can reduce the turning
radius of your vehicle by applying the
brakes to the inside rear wheel in
low-speed, high steering-angle maneuvers.
TRAIL TURN ASSIST
PRECAUTIONS
Note:
Do not use trail turn assist on dry,
hard surfaced roads. Doing so can produce
excessive noise, increase tire wear and may
damage drive line, or braking components.
Trail turn assist is only intended for slippery,
or loose surfaces.
You may hear noise from the anti-lock
brake system while trail turn assist is
active. This is normal operation.
TRAIL TURN ASSIST
LIMITATIONS
Trail turn assist can only be used when the
vehicle ’s four-wheel drive system is in the
four-wheel drive high (4H), or four-wheel
drive low (4L) modes.
Trail Turn Assist cannot be used when the
vehicle ’s rear differential is locked. If the
rear differential has recently been locked
prior to Trail Turn Assist being turned on,
Trail Turn Assist may not activate until it
can confirm that the rear differential is
unlocked.
SWITCHING TRAIL TURN
ASSIST ON AND OFF
You can switch the trail turn assist on or
off from the features section of the vehicle
on screen display.
1. Press Features on the touchscreen.
2. Press
Trail Turn Assist. 3. Switch
Trail Turn Assist on or off.
Switch trail turn assist on when your
vehicle is in four-wheel drive high (4H) or
four-wheel drive low (4L).
The system activates when the:
• Vehicle speed is less than
12 mph
(19.3 km/h).
• Rear differential is fully unlocked.
• Steering wheel is almost fully turned
to the left or right.
Switch trail turn assist off by performing
any of the following:
• Switch trail turn assist off from the
features section of the vehicle on
screen display.
• Select two-wheel drive high, or
four-wheel drive auto.
• Switch on the rear locking differential.
TRAIL TURN ASSIST
INDICATORS When trail turn assist is on, one
of these two indicators will be
displayed, depending on the
direction of the vehicle
’s last
turn. When the feature is on but
not in use, the indicator light will
be gray. When the feature is active the
indicator light will be green.

ELECTRIC POWER STEERING
ELECTRIC POWER STEERING
PRECAUTIONS
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 vehicle off. After at least 10
seconds, switch the vehicle 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.
Adapt your speed and driving behavior
according to reduced steering assist.
Extreme continuous steering may increase
the effort to steer. This occurs to prevent
internal overheating and damage to the
steering system. If this occurs, you will not
lose the ability to steer your vehicle
manually nor will it cause damage to the
system. Normal steering and driving allows
the system to cool down and steering
assist returns to normal.
Note: There is no fluid reservoir to check or
fill. ELECTRIC POWER STEERING
ADAPTIVE STEERING
(If Equipped)
The adaptive steering system 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
continuously monitors for faults. If the
system detects a fault, a message appears
in the information display. If a red warning
message displays, stop your vehicle as soon
as it is safe to do so. The message could
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.
Note: The system has a locking device. It
remains mechanically locked at a fixed
steering ratio with the lock engaged. You
may notice a click when you turn your
vehicle on or off.
Note: If your vehicle loses electrical power
or detects a fault when you are driving, the
system shuts down and you retain a normal
steering function with a fixed steering ratio.
During this time, it is possible that the
steering wheel could not be straight when
the vehicle is driving straight ahead. In
addition, you could notice that the steering
wheel angle required to steer your vehicle
could be different.
332
F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Steering

Note:
During parking maneuvers, the
adaptive steering system balances the driver
workload for various steering wheel inputs
and vehicle loading conditions. Under
extreme operating conditions the system
locking device could engage. This strategy
prevents overheating and permanent
damage to the adaptive steering system.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Adaptive Learning
Adaptive learning helps correct road
irregularities and improves overall handling
and steering. It communicates with the
brake system to help operate advanced
stability control and crash avoidance
systems. Additionally, whenever you
disconnect the battery or install a new
battery, you must drive your vehicle a short
distance before the system relearns the
strategy and reactivates all systems. STEERING –

the steering wheel to point the guide lines
toward an intended path. If the steering
wheel position changes while reversing,
your vehicle might deviate from the
intended path. The fixed and active guide lines fade in and
out depending on the steering wheel
position. The active guide lines do not
display when the steering wheel position
is straight.
Use caution while reversing. Objects in the
red zone are closest to your vehicle and
objects in the green zone are farther away.
Objects get closer to your vehicle as they
move from the green zone to the yellow or
red zones. Use the side view mirrors and
rear view mirror to get better coverage on
both sides and rear of your vehicle.
Note:
Active guide lines and fixed guide
lines are only available when the
transmission is in reverse (R).
Note: The centerline is only available if the
active or fixed guide lines are on.
