2021 FORD F-150 Owners Manual

•
High-back booster seats If, with a backless booster seat, you cannot
find a seating position that adequately
supports your child's head, a high-back
booster seat would be a better choice.
Children and booster seats vary in size and
shape. Choose a booster that keeps the
lap belt low and snug across the hips,
never up across the stomach, and lets you
adjust the shoulder belt to cross the chest
and rest snugly near the center of the
shoulder.
The following drawings compare the ideal
fit to a shoulder belt uncomfortably close
to the neck and a shoulder belt that could
slip off the shoulder. The drawings also
show how the lap belt should be low and
snug across the child's hips.

If the booster seat slides on the vehicle
seat upon which it is being used, placing a
rubberized mesh sold as shelf or carpet
liner under the booster seat may improve
this condition. Do not use any item thicker
than this under the booster seat. Check
with the booster seat manufacturer's
instructions.
CHILD SAFETY LOCKS (IF
EQUIPPED) WARNING:
You cannot open the
rear doors from inside if you have put the
child safety locks on. A child safety lock is on the rear edge of
each rear door. You must switch the child
safety lock separately on each door.
Left-Hand Side

lock on and counterclockwise to switch it
off. Right-Hand Side

SEATBELT PRECAUTIONS
WARNING: Always drive and ride
with your seatback upright and the lap
belt snug and low across the hips. WARNING:
Children must always
be properly restrained. WARNING:
Do not allow a
passenger to hold a child on their lap
when your vehicle is moving. Failure to
follow this instruction could result in
personal injury or death in the event of a
sudden stop or crash. WARNING:
All occupants of your
vehicle, including the driver, should
always properly wear their seatbelts,
even when an airbag supplemental
restraint system is provided. Failure to
properly wear your seatbelt could
seriously increase the risk of injury or
death. WARNING:
It is extremely
dangerous to ride in a cargo area, inside
or outside of a vehicle. In a crash, people
riding in these areas are more likely to be
seriously injured or killed. Do not allow
people to ride in any area of your vehicle
that is not equipped with seats and
seatbelts. Make sure everyone in your
vehicle is in a seat and properly using a
seatbelt. Failure to follow this warning
could result in serious personal injury or
death. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
seatbelt. WARNING:
Each seating position
in your vehicle has a specific seatbelt
assembly made up of one buckle and
one tongue designed to be used as a pair.
Use the shoulder belt on the outside
shoulder only. Never wear the shoulder
belt under the arm. Never use a single
seatbelt for more than one person. WARNING:
Even with advanced
restraints systems, properly restrain
children 12 and under in a rear seating
position. Failure to follow this could
seriously increase the risk of injury or
death. WARNING:
Seatbelts and seats
may be hot in a vehicle that is in the
sunshine. The hot seatbelts or seats may
burn a small child. Check seat covers and
buckles before you place a child
anywhere near them. WARNING:
If your vehicle is
involved in a crash, have the seatbelts
and associated components inspected
as soon as possible. Failure to follow this
instruction could result in personal injury
or death.
All seating positions in this vehicle have
seatbelts. All occupants of the vehicle
should properly wear their seatbelts, even
when an airbag supplemental restraint
system is provided.
The seatbelt system consists of:
• Lap and shoulder seatbelts.
• A shoulder seatbelt with automatic
locking mode, except driver seatbelt.
• Height adjusters at the front outermost
seating positions.
• Seatbelt pretensioners at the front
outermost and rear outermost seating
positions.

A seatbelt warning light and
chime.
Crash sensors and monitoring
system with readiness indicator.
The seatbelt pretensioners are designed
to tighten the seatbelts when activated. In
frontal and near-frontal crashes, the
seatbelt pretensioners may be activated
alone or, if the crash is of sufficient severity,
together with the front airbags. In side
crashes and rollovers, the pretensioners
will be activated when the Safety Canopy
is activated.
FASTENING AND
UNFASTENING THE
SEATBELTS
This applies to all seating positions, except
for the front center position of Super Cab
and Crew Cab. 1. Insert the seatbelt tongue into the
buckle until you hear a snap and feel it
latch. 2. Press the button to release the
seatbelt.
Using the Seatbelt With Cinch
Tongue
This applies to the front center seating
position of Super Cab and Crew Cab.
The cinch tongue slides up and down the
seatbelt webbing when you stow the
seatbelt or when you put the seatbelts on.
When you buckle the seatbelt, the cinch
tongue allows you to shorten the lap
portion, but pinches the webbing to keep
the lap portion from getting longer. The
cinch tongue is designed to slip during a
crash, so wear the shoulder belt properly
and do not allow any slack in either the lap
or shoulder portions.
Fastening the Cinch Tongue WARNING: Always drive and ride
with your seatback upright and the lap
belt snug and low across the hips.
1. Pull the seatbelt from the retractor so that the shoulder belt portion of the
seatbelt crosses your shoulder and
chest.
2. Make sure the belt is not twisted. If the
belt is twisted, remove the twist.

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.

ENGAGING AUTOMATIC LOCKING
MODE
1. Fasten the combination lap and
shoulder belt.
2. Grasp the shoulder portion and pull downward until you pull the entire belt
out.
3. Allow the belt to retract. As the belt retracts, you will hear a clicking sound.
This indicates the seatbelt is now in the
automatic locking mode.
DISENGAGING AUTOMATIC
LOCKING MODE
Unbuckle the combination lap and
shoulder belt and allow it to retract
completely to disengage the automatic
locking mode and activate the vehicle
sensitive locking mode. ADJUSTING THE SEATBELTS
DURING PREGNANCY WARNING: Always ride and drive
with your seatback upright and properly
fasten your seatbelt. Fit the lap portion
of the seatbelt snugly and low across
the hips. Position the shoulder portion of
the seatbelt across your chest. Pregnant
women must follow this practice. See
the following figure. Pregnant women should always wear their
seatbelt. Position the lap belt portion of a
combination lap and shoulder belt low
across the hips below the belly and worn
as tight as comfort allows. Position the
shoulder belt to cross the middle of the
shoulder and the center of the chest.
ADJUSTING THE SEATBELT
HEIGHT
WARNING:
Position the seatbelt
height adjuster so that the seatbelt rests
across the middle of your shoulder.
Failure to adjust the seatbelt correctly
could reduce its effectiveness and
increase the risk of injury in a crash.

ADJUSTING THE SEATBELT
LENGTH 1.
Pull some seatbelt webbing out of the

tongue so that it is parallel to the
webbing and slide the tongue up.
3. Provide enough lap belt length so that
the tongue can reach the buckle.
SEATBELT REMINDER
HOW DOES THE SEATBELT
REMINDER WORK
This feature supplements the seatbelt
warning function by providing additional
reminders that intermittently sound a tone
and illuminate the seatbelt warning lamp
when you are in the driver seat or you have
a front seat passenger and a seatbelt is
unbuckled.
The system uses information from the
front passenger sensing system to
determine if a front seat passenger is
present and therefore potentially in need
of a warning. To avoid the system
switching on the Belt-Minder feature for
objects you place on the front passenger
seat, only the front seat passengers receive
warnings as determined by the front
passenger sensing system.
If the Belt-Minder warnings expire
(warnings for about five minutes) for one
passenger (driver or front passenger), the
other passenger can still cause the
Belt-Minder feature to switch on.
