2015 FORD F150 Owners Manual

If the tire pressure monitoring
system indicator is flashing, the
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
may be damaged.
Safety Practices
WARNINGS
If your vehicle is stuck in
snow, mud, or sand, do not
rapidly spin the tires; spinning the
tires can tear the tire and cause
an explosion. A tire can explode in
as little as three to five seconds. Do not spin the wheels at
over 35 mph (56 km/h). The
tires may fail and injure a
passenger or bystander. Driving habits have a great deal
to do with your tire mileage and
safety.
*Observe posted speed limits
*Avoid fast starts, stops and turns
*Avoid potholes and objects on
the road
*Do not run over curbs or hit the
tire against a curb when parking Highway Hazards
No matter how carefully you drive
there
’s always the possibility that
you may eventually have a flat tire
on the highway. Drive slowly to the
closest safe area out of traffic.
This may further damage the flat
tire, but your safety is more
important.
If you feel a sudden vibration or
ride disturbance while driving, or
you suspect your tire or vehicle
has been damaged, immediately
reduce your speed. Drive with
caution until you can safely pull
off the road. Stop and inspect the
tires for damage. If a tire is
under-inflated or damaged,
deflate it, remove wheel and
replace it with your spare tire and
wheel. If you cannot detect a
cause, have the vehicle towed to
the nearest repair facility or tire
dealer to have the vehicle
inspected.
Tire and Wheel Alignment
A bad jolt from hitting a curb or
pothole can cause the front end
of your vehicle to become
misaligned or cause damage to
your tires. If your vehicle seems to
pull to one side when you’re
driving, the wheels may be out of
alignment. Have an authorized
dealer check the wheel alignment
periodically.

F-150 (), enUSA, First Printing Wheels and Tires

Wheel misalignment in the front
or the rear can cause uneven and
rapid treadwear of your tires and
should be corrected by an
authorized dealer. Front-wheel
drive vehicles and those with an
independent rear suspension may
require alignment of all four
wheels.
The tires should also be balanced
periodically. An unbalanced tire
and wheel assembly may result in
irregular tire wear.
Tire Rotation
WARNING
If the tire label shows
different tire pressures for the
front and rear tires and the vehicle
is equipped with a tire pressure
monitoring system, then the
settings for the system sensors
need to be updated. Always
perform the system reset
procedure after tire rotation. If the
system is not reset, it may not
provide a low tire pressure
warning when necessary. See the
tire pressure monitoring system
reset procedure in this chapter. Note:
If your tires show uneven
wear ask an authorized dealer to
check for and correct any wheel
misalignment, tire imbalance or
mechanical problem involved
before tire rotation. Note:
Your vehicle may be
equipped with a dissimilar spare
wheel and tire assembly. A
dissimilar spare wheel and tire
assembly is defined as a spare
wheel and tire assembly that is
different in brand, size or
appearance from the road tires and
wheels. If you have a dissimilar
spare wheel and tire assembly it is
intended for temporary use only
and should not be used in a tire
rotation.
Note: After having your tires
rotated, inflation pressure must be
checked and adjusted to the
vehicle requirements.
Rotating your tires at the
recommended interval (as
indicated in the Scheduled
Maintenance chapter) will help
your tires wear more evenly,
providing better tire performance
and longer tire life.
Rear-wheel drive vehicles and
four-wheel drive vehicles (front
tires at left of diagram) Sometimes irregular tire wear can
be corrected by rotating the tires.

USING SNOW CHAINS
WARNING
Snow tires must be the same size,
load index, speed rating as those
originally provided by Ford. Use of
any tire or wheel not recommended by
Ford can affect the safety and
performance of your vehicle, which could
result in an increased risk of loss of vehicle
control, vehicle rollover, personal injury and
death. Additionally, the use of
non-recommended tires and wheels could
cause steering, suspension, axle, transfer
case or power transfer unit failure. Note:
The suspension insulation and
bumpers will help prevent vehicle damage.
Do not remove these components from your
vehicle when using snow tires and chains.
The tires on your vehicle have all-weather
treads to provide traction in rain and snow.
However, in some climates, you may need
to use snow tires and cables. If you need
to use cables, it is recommended that steel
wheels (of the same size and
specifications) be used, as cables may chip
aluminum wheels.
Follow these guidelines when using snow
tires and chains:
• If possible, avoid fully loading your
vehicle.
• Use only cable type chains or chains
offered by Ford/Lincoln as an
accessory or equivalent. Other
conventional link type chains may
contact and cause damage to the
vehicle's wheel house and/or body.
• Do not install chains on the front tires
as this may interfere with suspension
components. •
Only certain snow cables or chains
have been approved by Ford/Lincoln
as safe for use on your vehicle with the
following tires: 245/70R17,
LT245/70R17, 265/70R17 and
265/60R18.
• You should install snow cables or
chains that have been rated as SAE
Class S.
• Install chains securely, verifying that
the chains do not touch any wiring,
brake lines, or fuel lines.
• Do not exceed 30 mph (50 km/h) or
less if recommended by the chain
manufacturer while using snow chains.
• Drive cautiously. If you hear the chains
rub or bang against your vehicle, stop
and retighten the chains. If this does
not work, remove the chains to prevent
damage to your vehicle.
• Remove the tire chains when they are
no longer needed. Do not use tire
chains on dry roads.
• Purchase chains or cables from a
manufacturer that clearly labels body
to tire dimension restrictions. The snow
chains or cables must be mounted in
pairs on the rear tires only.
If you have any questions regarding snow
chains or cables, please contact your
Ford/Lincoln authorized dealer.

TIRE PRESSURE MONITORING
SYSTEM
WARNING
The tire pressure monitoring system
is not a substitute for manually
checking tire pressure. The tire
pressure should be checked periodically
(at least monthly) using a tire gauge, see
Inflating your tires in this chapter. Failure
to properly maintain your tire pressure
could increase the risk of tire failure, loss
of control, vehicle rollover and personal
injury. 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.
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.
The tire pressure monitoring system
complies with part 15 of the FCC rules and
with RSS-210 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.

Changing Tires With a Tire
Pressure Monitoring System
Note:
Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and is
not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor
You should always have your tires serviced
by an authorized dealer.
Check the tire pressure periodically (at
least monthly) using an accurate tire
gauge. See Inflating Your Tires in this
chapter. Understanding Your Tire Pressure
Monitoring System
The tire pressure monitoring system
measures pressure in your four road tires
and sends the tire pressure readings to
your vehicle. The low tire pressure warning
light will turn on if the tire pressure is
significantly low. Once the light is
illuminated, your tires are under-inflated
and need to be inflated to the
manufacturer
’s recommended tire
pressure. Even if the light turns on and a
short time later turns off, your tire pressure
still needs to be checked.
When Your Temporary Spare Tire is
Installed
When one of your road tires needs to be
replaced with the temporary spare, the
system will continue to identify an issue to
remind you that the damaged road wheel
and tire assembly needs to be repaired and
put back on your vehicle.
To restore the full function of the tire
pressure monitoring system, have the
damaged road wheel and tire assembly
repaired and remounted on your vehicle.
When You Believe Your System is Not
Operating Properly
The main function of the tire pressure
monitoring system is to warn you when
your tires need air. It can also warn you in
the event the system is no longer capable
of functioning as intended. See the
following chart for information concerning
your tire pressure monitoring system:

When Inflating Your Tires
When putting air into your tires (such as at
a gas station or in your garage), the tire
pressure monitoring system may not
respond immediately to the air added to
your tires.
It may take up to two minutes of driving
over 20 mph (32 km/h) for the light to turn
off after you have filled your tires to the
recommended inflation pressure
How Temperature Affects Your Tire
Pressure
The tire pressure monitoring system
monitors tire pressure in each pneumatic
tire. While driving in a normal manner, a
typical passenger tire inflation pressure
may increase about 2 to 4 psi (14 to 28
kPa) from a cold start situation. If the
vehicle is stationary overnight with the
outside temperature significantly lower
than the daytime temperature, the tire
pressure may decrease about 3 psi (21
kPa) for a drop of 30°F (17°C) in ambient
temperature. This lower pressure value
may be detected by the tire pressure
monitoring system as being significantly
lower than the recommended inflation
pressure and activate the system warning
light for low tire pressure.
If the low tire pressure warning light is on,
visually check each tire to verify that no tire
is flat. If one or more tires are flat, repair as
necessary. Check the air pressure in the
road tires. If any tire is under-inflated,
carefully drive the vehicle to the nearest
location where air can be added to the
tires. Inflate all the tires to the
recommended inflation pressure.
Tire Pressure Monitoring System Reset
Procedure WARNING
To determine the required
pressure(s) for your vehicle, see the
Safety Compliance Certification
Label (affixed to either the door hinge
pillar, door-latch post, or the door edge
that meets the door-latch post, next to the
driver's seating position), or Tire Label
located on the B-Pillar or the edge of the
driver's door. Note:
You need to perform the tire pressure
monitoring system reset procedure after
each tire rotation on vehicles that require
different recommended tire pressures in the
front tires as compared to the rear tires.
Overview
To provide the vehicle's load carrying
capability, some vehicles require different
recommended tire pressures in the front
tires as compared to the rear tires. The tire
pressure monitoring system equipped on
these vehicles is designed to illuminate the
low tire pressure warning light at two
different pressures; one for the front tires
and one for the rear tires.
Since tires need to be rotated to provide
consistent performance and maximum tire
life, the tire pressure monitoring system
needs to know when the tires are rotated
to determine which set of tires are on the
front and which are on the rear. With this
information, the system can detect and
properly warn of low tire pressures.
System reset tips:
348
F-150 (), enUSA, First Printing Wheels and Tires

•
To reduce the chances of interference
from another vehicle, perform the
system reset procedure at least three
feet (one meter) away from another
Ford Motor Company vehicle
undergoing the system reset procedure
at the same time.
• Do not wait more than two minutes
between resetting each tire sensor or
the system will time-out and the entire
procedure will have to be repeated on
all four wheels.
• A double horn will sound indicating the
need to repeat the procedure.
Performing the System Reset Procedure
Read the entire procedure before
attempting.
1. Drive the vehicle above 20 mph (32 km/h) for at least two minutes, then
park in a safe location where you can
easily get to all four tires and have
access to an air pump.
2. Place the ignition in the off position and
keep the key in the ignition.
3. Cycle the ignition to the on position with the engine off.
4. Turn the hazard flashers on then off three times. You must accomplish this
within 10 seconds. If the reset mode
has been entered successfully, the horn
will sound once, the system indicator
will flash and a message is shown in
the information display. If this does not
occur, please try again starting at Step
2. If after repeated attempts to enter
the reset mode, the horn does not
sound, the system indicator does not
flash and no message is shown in the
information display, seek service from
your authorized dealer. 5. Train the tire pressure monitoring
system sensors in the tires using the
following system reset sequence
starting with the left front tire in the
following clockwise order: Left front
(driver's side front tire), Right front
(passenger's side front tire), Right rear
(passenger's side rear tire), Left rear
(driver's side rear tire)
6. Remove the valve cap from the valve stem on the left front tire. Decrease the
air pressure until the horn sounds.
Note: The single horn chirp confirms
that the sensor identification code has
been learned by the module for this
position. If a double horn is heard, the
reset procedure was unsuccessful, and
you must repeat it.
7. Remove the valve cap from the valve stem on the right front tire. Decrease
the air pressure until the horn sounds.
8. Remove the valve cap from the valve stem on the right rear tire. Decrease the
air pressure until the horn sounds.
9. Remove the valve cap from the valve stem on the left rear tire. Decrease the
air pressure until the horn sounds.
Training is complete after the horn
sounds for the last tire trained (driver's
side rear tire), the system indicator
stops flashing, and a message is shown
in the information display.
10. Turn the ignition off. If two short horn
beeps are heard, the reset procedure
was unsuccessful and you must
repeat it. If after repeating the
procedure and two short beeps are
heard when the ignition is turned to
off, seek assistance from your
authorized dealer.
