MANUAL PARK RELEASE
WHAT IS MANUAL PARK RELEASE
Manual park release allows you to move
your transmission out of the park (P)
position in the event of an electrical
malfunction or emergency.
MANUAL PARK RELEASE
PRECAUTIONS WARNING: When doing this
procedure, you need to take the
transmission out of park (P) which
means your vehicle can roll freely. To
avoid unwanted vehicle movement,
always fully apply the parking brake prior
to doing this procedure. Use wheels
chocks if appropriate. WARNING:
If the parking brake is
fully released, but the brake warning
lamp remains illuminated, the brakes
may not be working properly. Have your
vehicle checked as soon as possible. WARNING:
Do not drive your
vehicle until you verify that the
stoplamps are working.
Use the manual park release to move your
transmission from the park (P) position in
the event of an electrical malfunction or
emergency. See

WHAT IS TRACTION CONTROL
The traction control system helps to avoid
drive wheel spin and loss of traction.
HOW DOES TRACTION
CONTROL WORK
If your wheels begin to spin, the loss of
traction can compromise steering control
and stability of the vehicle. The traction
control system applies the brakes to
individual wheels and when needed,
reduces engine power at the same time to
increase traction.
SWITCHING TRACTION
CONTROL ON AND OFF
WARNING: Operating your vehicle
with the traction control disabled could
lead to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death. The traction control system turns on each
time you switch the ignition on.
The button for the stability and traction
control system is on the instrument panel. Press and release the button to switch
traction control off. The stability control
system remains fully active, to switch it off,
press and hold the button for a few
seconds, then release.
When you switch traction control off, a
message and an illuminated icon appear
on the instrument cluster.
Press the switch again to turn the traction
control system back on to normal
operation.
If your vehicle is stuck in mud or snow,
switching traction control off may be
beneficial as this allows the wheels to spin.
Your vehicle may have MyKey restrictions
regarding this feature. See
What Is
MyKey (page 98).
TRACTION CONTROL
INDICATOR
Stability and Traction Control
Indicator If the indicator does not
illuminate when you switch the

HOW DOES STABILITY
CONTROL WORK
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo speakers may
interfere with and adversely affect the
electronic stability control system.
Reducing the effectiveness of the
electronic stability control system could
lead to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It's always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator's ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. WARNING: You are responsible for
controlling your vehicle at all times. The
system is designed to be an aid and does
not relieve you of your responsibility to
drive with due care and attention. Failure
to follow this instruction could result in
the loss of control of your vehicle,
personal injury or death.
If a driving condition activates either the
stability control or traction control you may
experience the following conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
Electronic stability control enhances your
vehicle ’s ability to prevent skids or lateral
slides by applying brakes to one or more
of the wheels individually and, if necessary,
reducing engine power.
Roll Stability Control
Roll stability control enhances your
vehicle ’s ability to prevent rollovers by
detecting your vehicle ’s roll motion and
the rate at which it changes by applying
the brakes to one or more wheels
individually.
Curve Control
Curve control enhances your vehicle ’s
ability to follow the road when cornering
severely or avoiding objects in the roadway.
Curve control operates by reducing engine
power and, if necessary, applying brakes
to one or more of the wheels individually.

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.

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 –

WHAT IS DRIVE MODE
CONTROL
Your vehicle has various drive modes that
you can select for different driving
conditions. Depending on the drive mode
that you select, the system adjusts various
vehicle settings.
HOW DOES DRIVE MODE
CONTROL WORK - RAPTOR
Selectable drive modes change various
electronic and mechanical settings within
your vehicle to tailor its performance and
driving characteristics to on-road or
off-road driving conditions. Steering feel
and effort, traction control, stability
control, chassis controls, powertrain
response, transmission shift points,
four-wheel driveline settings, exhaust noise
level and suspension dampening are
automatically altered to a pre-determined
setting depending upon the drive mode
that you select.
Note:
Your vehicle has diagnostic checks
that continuously monitor all systems for
proper operation. If a drive mode is
unavailable due to a system fault, your
vehicle defaults to normal mode and the
driveline remains in the four-wheel drive
setting that you last selected prior to the
system fault. Note:
Your vehicle reverts to normal mode
each time you start it. If you shut your
vehicle off in a drive mode other than
normal mode, at startup the instrument
cluster screen displays a pop-up asking if
you would like to return to your last used
drive mode. If you select yes to the pop-up,
your vehicle returns to the last selected drive
mode and the default four-wheel driveline
setting associated with that drive mode. If
you select no, your vehicle remains in normal
mode and the default four-wheel driveline
setting associated with that drive mode. If
you do not select yes or no, the pop-up
message times out, your vehicle remains in
normal mode, and the four-wheel driveline
setting remains in its last used setting.
Note: Do not use the electronic locking
differential on dry, hard surfaces. Doing so
produces excessive noise, vibration and
increases tire wear. See Electronic Locking
Differential (page 301).
