TPMS FORD F-150 2021 Owners Manual

USING BEAD-LOCK WHEELS -
RAPTOR
Your vehicle comes with unique wheels
matched to the tires. To avoid damage to
your wheels:
•
Maintain proper tire pressure.
• Due to extreme tire and wheel width,
do not take your vehicle through an
automatic car wash that uses
mechanical tracks, as wheel damage
may result.
• When installing wheels, always torque
lug nuts to specification with a torque
wrench.
• Inspect your wheels for damage on a
regular basis. If you have a damaged
wheel, replace it immediately.
• If you encounter an abnormally harsh
impact, inspect the outside tire wall of
your wheels, both inside and out, for
damage.
Note: Ford Performance only recommends
using bead-lock rings from Ford
Performance Parts, in conjunction with the
original equipment manufacturer (OEM)
tire. Any other combination using this wheel
could result in air loss or tire failure.
Note: Converting the bead-lock compatible
wheel to true bead-locks is for off-road use
only. We do not approve of the use of true
bead-locks for on-road driving.
If your vehicles equipped with the optional
bead lock compatible wheel, you can
convert this wheel to use a true bead-lock
ring, which allows operation at low tire
pressures when off-road to minimize the
risk of de-beading the tire. See your local
Ford Performance Parts Dealer for more
information. Tire Care WARNING: Always re-inflate tires
to recommended tire pressures before
the vehicle is operated on-road. The
recommended pressure is located on the
tire label or safety certification label,
located on the B-pillar, inside the driver's
door. WARNING:
After off-road use,
before returning to the road, check the
wheels and tires for damage. Off-road
use may cause damage to your wheels
and tires that can lead to tire failure, loss
of vehicle control, serious injury or death. WARNING:
Replace the wheels
and tires with the exact original brand,
size and construction that came
originally on your vehicle. Use of any
other wheel or tire combinations, even
with identical size ratings, may result in
insufficient running clearances, tire
rubbing and eventual puncture. Failure
to follow tire replacement
recommendations can lead to tire failure,
loss of vehicle control, serious injury or
death.
Note: If you have reduced your tire pressure
for off-road use, the tire pressure monitoring
system (TPMS) warning light then activates
in the instrument panel as a reminder to
re-inflate the tires before returning to the
road.

WHAT IS THE TIRE PRESSURE
MONITORING SYSTEM
The tire pressure monitoring
system measures the vehicle's
tire pressures. A warning lamp
illuminates if one or more tires are
significantly underinflated or if there is a
system malfunction.
TIRE PRESSURE MONITORING
SYSTEM OVERVIEW WARNING: If the tire pressure
monitor sensor becomes damaged it
may not function. 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:
To determine the
required pressure(s) for your vehicle, see
the Safety Compliance Certification
Label (on the door hinge pillar,
door-latch post or the door edge that
meets the door-latch post, next to the
driver seat) or the Tire Label on the
B-Pillar or the edge of the driver door. Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure
recommended by the vehicle manufacturer
on the vehicle placard or tire inflation
pressure label. (If your vehicle has tires of
a different size than the size indicated on
the vehicle placard or tire inflation pressure
label, you should determine the proper tire
inflation pressure for those tires).
As an added safety feature, your vehicle
has been equipped with a Tire Pressure
Monitoring System (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the low tire pressure telltale
illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly under-inflated tire causes the
tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the
vehicle
’s handling and stopping ability.
Please note that the TPMS is not a
substitute for proper tire maintenance, and
it is the driver ’s responsibility to maintain
correct tire pressure, even if under-inflation
has not reached the level to trigger
illumination of the TPMS low tire pressure
telltale.
Your vehicle has also been equipped with
a TPMS malfunction indicator to indicate
when the system is not operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence
will continue upon subsequent vehicle
start-ups as long as the malfunction exists.

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

When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
WARNING: Changes or
modifications not expressively approved
by the party responsible for compliance
could void the user's authority to operate
the equipment. The term "IC:" before the
radio certification number only signifies
that Industry Canada technical
specifications were met.
This device complies with Part 15 of the
FCC Rules and with License exempt RSS
Standards of Industry Canada. Operation
is subject to the following two conditions:
1. This device may not cause harmful interference, and
2. This device must accept any interference received, including
interference that may cause undesired
operation. TIRE PRESSURE MONITORING
SYSTEM PRECAUTIONS WARNING:
The tire pressure
monitoring system is not a substitute for
manually checking tire pressures. You
should periodically check tire pressures
using a pressure gauge. Failure to
correctly maintain tire pressures could
increase the risk of tire failure, loss of
control, vehicle rollover and personal
injury. 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.
Note: The use of tire sealants can damage
the tire pressure monitoring system.
TIRE PRESSURE MONITORING
SYSTEM LIMITATIONS
When the outside temperature drops
significantly, the tire pressure could
decrease and activate the low tire pressure
warning lamp.
The warning lamp could also illuminate
when you use a spare wheel, or tire sealant
from the inflator kit.
Note: Regularly checking the vehicle tire
pressures can reduce the possibility for the
warning lamp to illuminate due to outside
air temperature changes.
Note: After you inflate the tires to the
recommended pressure it could take up to
two minutes of driving over
20 mph
(32 km/h) for the warning indicator to turn
off.
