2021 FORD F-150 Check Every Month

WHAT IS THE REAR
OCCUPANT ALERT SYSTEM
The rear occupant alert system monitors
vehicle conditions and notifies you to check
for rear seat occupants when you switch
the ignition off.
HOW DOES THE REAR
OCCUPANT ALERT SYSTEM
WORK
The system monitors when rear doors have
been opened and closed to indicate the
potential presence of an occupant in the
rear seat.
A message displays in the information and
entertainment display screen and an
audible warning sounds when you switch
the ignition off after any of the following
conditions have been met:
•
A rear door is opened or closed while
the ignition is on.
• You switch the ignition on within 15
minutes of a rear door opening and
closing.
• You switch the ignition on within 15
minutes of the alert having displayed
or sounded.
REAR OCCUPANT ALERT
SYSTEM PRECAUTIONS WARNING: On hot days, the
temperature inside the vehicle can rise
very quickly. Exposure of people or
animals to these high temperatures for
even a short time can cause death or
serious heat related injuries, including
brain damage. Small children are
particularly at risk. WARNING:
Do not leave children
or pets unattended in your vehicle.
Failure to follow this instruction could
result in personal injury or death.
REAR OCCUPANT ALERT
SYSTEM LIMITATIONS
The system does not detect the presence
of objects or passengers in the rear seat.
It monitors when rear doors are opened
and closed.
Note: It is possible to receive an alert when
there is no rear seat occupant, but alert
conditions are met.
Note: It is possible to receive no alert when
there is an occupant in the rear seat, if alert
conditions are not met. For example, if a rear
seat occupant does not enter the vehicle
through a rear door.
Note: The audible warning does not sound
when the front door is opened before you
switch the ignition off.

CHECKING THE TIRE
PRESSURES
Safe operation of your vehicle
requires that your tires are
properly inflated. Every day before
you drive, check your tires.
At least once a month and before
long trips, inspect each tire and
check the tire pressure with a tire
gauge. Inflate all tires to the
recommended inflation pressure.
See Inflating the Tires (page
555).
INFLATING THE TIRES WARNING: Under-inflation
is the most common cause of
tire failures and may result in
severe tire cracking, tread
separation or blowout, with
unexpected loss of vehicle
control and increased risk of
injury. Under-inflation increases
sidewall flexing and rolling
resistance, resulting in heat
buildup and internal damage to
the tire. It also may result in
unnecessary tire stress, irregular
wear, loss of vehicle control and
accidents. A tire can lose up to
half of its air pressure and not
appear to be flat! WARNING:
Do not use the
tire pressure displayed in the
information display as a tire
pressure gauge. Failure to follow
this instruction could result in
personal injury or death.
Use the recommended cold
inflation pressure for optimum tire
performance and wear.
Under-inflation or over-inflation
may cause uneven treadwear
patterns.
Inflate your tires to the
recommended inflation pressure
even if it is less than the maximum
inflation pressure information
found on the tire. You can find the
tire label with the recommended
tire inflation pressure next to the
tire size on the B-Pillar or the edge
of the driver door.
The recommended tire inflation
pressure is also found on the
Safety Compliance Certification
Label, affixed to either the door
hinge pillar, door-latch post, or the
door edge that meets the
door-latch on the B-pillar, or on
the edge of the driver door.
Failure to follow the tire pressure
recommendations can cause
uneven treadwear patterns and
adversely affect the way your
vehicle handles.

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

1. Lay the tire on the ground with the
valve stem facing up.
2. Slide the wheel partially under the vehicle and install the retainer through
the wheel center. Pull on the cable to
align the components at the end of the
cable.
3. Turn the jack handle clockwise until you raise the tire to its stowed position
underneath the vehicle. The effort to
turn the jack handle increases
significantly and the spare tire carrier
ratchets or slips when you raise the tire
to the maximum tightness. Tighten to
the point where the ratchet or slip
occurs a minimum of three times, as
indicated by an audible click each time.
The spare tire carrier does not allow
you to overtighten. If the spare tire
carrier ratchets or slips with little effort,
have your vehicle checked as soon as
possible.
4. Check that the tire lies flat against the frame and you properly tighten it. Try
to push or pull, then turn the tire to be
sure it does not move. Loosen and
retighten, if necessary. Failure to
properly stow the spare tire could
result in failure of the winch cable and
loss of the tire.
5. Repeat this tightness check procedure
when servicing the spare tire pressure,
every six months, as per your scheduled
maintenance information, or at any
time that the spare tire gets disturbed
through service of other components.
6. If removed, install the spare tire lock into the bumper drive tube with the
spare tire lock key and jack handle. Stowing the Vehicle Jack and Tool
Bag
1. Turn the lead screw eyelet to adjust
the jack up or down until the stowage
markings on the upper channel align
with the lower channel. 2. Place the tools inside of the tool bag.

GENERAL MAINTENANCE
INFORMATION
Why Maintain Your Vehicle?
Carefully following the maintenance
schedule helps protect against major repair
expenses resulting from neglect or
inadequate maintenance and may help to
increase the value of your vehicle when
you sell or trade it. Keep all receipts for
completed maintenance with your vehicle.
It is important that you have your vehicle
serviced at the proper times. These
intervals serve two purposes: first is to
maintain the reliability of your vehicle and
the second is to keep the cost of owning
your vehicle down.
It is your responsibility to have all
scheduled maintenance performed and to
make sure that the materials used meet
the specifications identified in this owner's
manual. See Capacities and
Specifications (page 574).
Failure to perform scheduled maintenance
and regularly inspect your vehicle may
result in vehicle damage not covered by
the vehicle Warranty.
Why Maintain Your Vehicle at Your
Dealership?
Our Genuine Replacement Parts
Dealerships stock our parts and our
authorized branded re-manufactured
replacement parts. These parts meet or
exceed our specifications. Parts installed
at your dealership carry a nationwide
24-month or unlimited mile (kilometer)
parts and labor limited warranty.
If you do not use our authorized parts they
may not meet our specifications and could
affect emissions compliance. Protecting Your Investment
Maintenance is an investment that pays
dividends in the form of improved
reliability, durability and resale value. To
maintain the proper performance of your
vehicle and its emission control systems,
make sure you have scheduled
maintenance performed at the designated
intervals.
Your vehicle comes with the Intelligent
Oil-Life Monitor system, a message
appears in the information display at the
proper oil change interval. This interval
may be up to one year or
10,000 mi
(16,000 km), hybrid vehicles could exceed
10,000 mi (16,000 km).
When the oil change message appears in
the information display, it is time for an oil
change. Make sure you perform the oil
change within two weeks or
500 mi
(800 km) of the message appearing. Make
sure to reset the Intelligent Oil-Life Monitor
after each oil change. See
Resetting the
Engine Oil Change Reminder (page 511).
If your information display resets
prematurely or becomes inoperative, you
should perform the oil change interval at
six months or
5,000 mi (8,000 km) from
your last oil change. Never exceed one year
or
10,000 mi (16,000 km) between oil
change intervals.
You can drive high performance vehicles
in such a way that may lead to higher oil
consumption including extended time at
high engine speeds, high loads, engine
braking, hard cornering maneuvers, track
and off-road usage. Under these
conditions, oil consumption of
approximately 1 quart per 500 miles (1 liter
per 800 km) is possible. Check the engine
oil level at every refueling and adjust to
maintain proper levels to avoid engine
damage.

It is important to rely upon your dealership
to properly diagnose and repair your
vehicle.
We strongly recommend only using our
genuine or our authorized re-manufactured
replacement parts engineered for your
vehicle.
Additives and Chemicals
We do not recommend using chemicals or
additives not approved by us as part of
your vehicle
’s normal maintenance. Please
consult your warranty information.
Oils, Fluids and Flushing
In many cases, fluid discoloration is a
normal operating characteristic and, by
itself, does not necessarily indicate a
concern or that the fluid needs to be
changed. Have discolored fluids that also
show signs of overheating or foreign
material contamination checked
immediately. Make sure to change the vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a
viable way to change fluid for many vehicle
sub-systems during scheduled
maintenance. It is critical that systems are
flushed only with new fluid that is the same
as that required to fill and operate the
system or using our approved flushing
chemical.
