3. Insert the belt tongue into the proper
buckle for your seating position until
you hear a snap and feel it latch.
4. Make sure you securely fasten the tongue to the buckle by pulling on the
tongue.
While you are fastened in the seatbelt, the
seatbelt with a cinch tongue adjusts to
your movement. However, if you brake
hard, turn hard, or if your vehicle receives
an impact of 5 mph (8 km/h) or more, the
seatbelt locks and helps reduce your
forward movement.
SENSITIVE LOCKING MODE
WHAT IS SENSITIVE LOCKING
MODE
Sensitive locking mode is a seatbelt
retractor feature that allows shoulder belt
length adjustment according to your
movements and locking in response to
vehicle movement.
HOW DOES SENSITIVE LOCKING
MODE WORK
If the driver suddenly brakes, turns a corner
sharply, or the vehicle receives an impact
of about 5 mph (8 km/h) or more, the
seatbelts lock to help reduce forward
movement of the driver and passengers.
In addition, the seatbelt retractor locks if
you pull the seatbelt webbing out too
quickly. If the retractor locks, slowly lower
the height adjuster to allow the seatbelt
to retract.
If the retractor does not unlock, pull the
seatbelt out slowly then feed a small
length of webbing back toward the stowed
position. For rear seatbelts, recline the rear seat
backrest or push the seat backrest cushion
away from the seatbelt. Feed a small
length of webbing back toward the stowed
position.
AUTOMATIC LOCKING MODE
WHAT IS AUTOMATIC LOCKING
MODE
This feature keeps the seatbelts
pre-locked. The belt still retracts to remove
any slack in the shoulder belt.
WHEN TO USE AUTOMATIC
LOCKING MODE
Use this mode any time you install a child
restraint in a front seating position in a
Regular Cab, Super Cab, Crew Cab or any
rear seating position of a Super Cab or
Crew Cab. The optional front seat center
seatbelt in the Super Cab and Crew Cab
has a cinch mechanism. Properly restrain
children 12 years old and under in a rear
seat whenever possible. See
Child Safety
(page 49).
Note: Automatic locking mode is not
available on the driver seatbelt.

Note:
Do not store objects in the selector
lever stow bin, and be sure that the bottom
selector lever tray mat is flat inside the
selector lever stow bin.
Note: If there are objects in the stow bin
while stowing the selector lever, the selector
lever could come back to the upright park
(P) position.
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
Emergency Towing
(page 492).
Note: Do not engage the manual park
release with the engine on.
USING MANUAL PARK RELEASE
Activating the Manual Park
Release Cable
1. Apply the parking brake. See Electric
Parking Brake
(page 311).
Note: If vehicle battery is dead, for example,
no electrical power available, an external
power source may be required to apply the
parking brake.
2. Locate the manual park release cable access cover at the bottom of the
driver dash lower panel, under the
steering wheel.

BRAKE PRECAUTIONS
WARNING: Driving your vehicle
with the warning lamp on is dangerous.
A significant decrease in braking
performance may occur. It may take you
longer to stop your vehicle. Have your
vehicle checked as soon as possible.
Driving extended distances with the
parking brake engaged can cause brake
failure and the risk of personal injury.
Wet brakes result in reduced braking
efficiency. Gently press the brake pedal a
few times when leaving a car wash or
driving from standing water to dry the
brakes.
Note: Depending on applicable laws and
regulations in the country for which your
vehicle was originally built, the stoplamps
could flash during heavy braking. Following
this the hazard warning flashers could also
turn on when your vehicle comes to a stop.
ANTI-LOCK BRAKING SYSTEM
ANTI-LOCK BRAKING SYSTEM
LIMITATIONS
The anti-lock braking system does not
eliminate the risk of crash when:
• You drive too closely to the vehicle in
front of you.
• Your vehicle is hydroplaning.
• You take corners too fast.
• The road surface is poor.
Note: If the system activates, the brake
pedal could pulse and travel further.
Maintain pressure on the brake pedal. BRAKE OVER ACCELERATOR
- RAPTOR
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission to park (P),
switch the engine off and apply the parking
brake. Inspect the accelerator pedal for
any interference. If none are found and the
condition persists, have your vehicle towed
to the nearest authorized dealer.
Note:
Certain drive modes can disable
brake over accelerator for off-road driving.
BRAKE OVER ACCELERATOR

becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe

F-150 (TFD) Canada/United States of America, enUSA, Edition date: 202104, Second-Printing Brakes

CHECKING THE BRAKE FLUID
WARNING: Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death. WARNING:
Do not allow the fluid
to touch your skin or eyes. If this
happens, rinse the affected areas
immediately with plenty of water and
contact your physician. WARNING:
The brake system
could be affected if the brake fluid level
is below the MIN mark or above the MAX
mark on the brake fluid reservoir. 1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative
to the MIN and the MAX marks on the
reservoir.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our
specifications.

BRAKES –
TROUBLESHOOTING
BRAKES – WARNING LAMPS
If the ABS indicator illuminates
when you are driving, this
indicates a malfunction. Your
vehicle continues to have normal braking
without the anti-lock braking system
function. See an authorized dealer.
It also momentarily illuminates when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to
flash at any time, have the system checked
by an authorized dealer. The brake indicator momentarily
illuminates when you switch the
ignition on to confirm the lamp
is functional. It may also illuminate when
you apply the parking brake and the
ignition is on. If it illuminates when your
vehicle is moving, make sure the parking
brake is disengaged. If the parking brake
is disengaged, this indicates low brake fluid
level or a brake system fault. See an
authorized dealer.
BRAKES – FREQUENTLY ASKED
QUESTIONS
Is it normal for my brakes to make
noise?
Occasional brake noise is normal. If a
metal-to-metal, continuous grinding,
or continuous squeal sound is present,
the brake lining could be worn-out.
Have the system checked by an
authorized dealer. There is an electrical motor sound
when I press on the brake pedal or
activate the park brake switch. Is this
normal?
Yes, those sounds are the electronic
brake booster or the electronic park
brake operating.
Note: Brake dust could accumulate on the
wheels, even under normal driving
conditions. Some dust is normal as the
brakes wear and does not contribute to
brake noise. See Cleaning Wheels (page
535).
