2021 FORD F-150 brake sensor

WHAT IS TRAILER REVERSE
GUIDANCE
Trailer reverse guidance provides views
and graphics on the touchscreen to help
you steer your vehicle when you backup a
trailer.
HOW DOES TRAILER REVERSE
GUIDANCE WORK
Trailer reverse guidance uses a sticker or
sensor attached to the trailer to detect the
trailer angle relative to the towing vehicle
and provides instructions, graphics and
camera views on the touchscreen.
TRAILER REVERSE GUIDANCE
PRECAUTIONS
WARNING: Driving while distracted
can result in loss of vehicle control, crash
and injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the
safe operation of your vehicle. We
recommend against the use of any
hand-held device while driving and
encourage the use of voice-operated
systems when possible. Make sure you
are aware of all applicable local laws
that may affect the use of electronic
devices while driving. WARNING: This system is an extra
driving aid. It does not replace your
attention and judgment, or the need to
apply the brakes. This system does NOT
automatically brake your vehicle. If you
fail to press the brake pedal when
necessary, you may collide with another
vehicle. Note:
The system is not a substitute for
safe driving practices. Always be aware of
your vehicle and trailer combination, and
the surrounding environment.
Note: The system does not detect or
prevent your vehicle or trailer from making
contact with obstacles in the surrounding
environment.
Note: The front end of your vehicle swings
out when changing the direction of the
trailer.
Note: In certain conditions, the trailer could
turn faster or the trailer angle could increase
more than anticipated. Always monitor the
clearance between the trailer and vehicle
and the surroundings.
SETTING UP TRAILER
REVERSE GUIDANCE FOR A
CONVENTIONAL TRAILER
CONFIGURING THE TRAILER
You must configure a trailer in the system
to use trailer reverse guidance. This is a
one-time setup process and the trailer
information is saved in the system for the
next time you use that trailer.
The system only works with conventional
trailers. It does not work with other types
including fifth-wheel and gooseneck. The
following illustration shows examples of
conventional trailers on the left-hand side.
Note: Trailer reverse guidance camera
views are available with no trailer setup.
However, complete functionality including
graphics and automatic view switching is
enabled by setup. Setup is required to
enable trailer backup assistance.

For longer, trouble-free operation, keep the
top of the battery clean and dry and the
battery cables tightly fastened to the
battery terminals. If any corrosion is
present on the battery or terminals, remove
the cables from the terminals and clean
with a wire brush. You can neutralize the
acid with a solution of baking soda and
water.
We recommend that you disconnect the
negative battery cable terminal from the
battery if you plan to store your vehicle for
an extended period.
Note:
If you only disconnect the negative
battery cable terminal, make sure it is
isolated or placed away from the battery
terminal to avoid unintended connection or
arcing.
To maintain correct operation of the
battery management system, if you add
any electrical devices to your vehicle, do
not connect the ground connection directly
to the negative battery terminal. A
connection at the negative battery terminal
can cause inaccurate measurements of
the battery condition and potential
incorrect system operation.
Note: If you add electrical accessories or
components to your vehicle this may
adversely affect battery performance,
durability and the performance of other
electrical systems on your vehicle.
If you replace the battery make sure it
matches the electrical requirements of
your vehicle.
If you disconnect or replace the battery
and your vehicle has an automatic
transmission, it must relearn its adaptive
strategy. Because of this, the transmission
may shift firmly when first driven. This is
normal operation while the transmission
fully updates its operation to optimum
shift feel. Remove and Reinstall the Battery
To disconnect or remove the battery, do
the following:
1.
Apply the parking brake and switch the
ignition off.
2. Switch all electrical equipment off, for
example lights and radio.
3. Wait a minimum of two minutes before
disconnecting the battery.
Note: The engine management system has
a power hold function and remains powered
for a period of time after you switch the
ignition off. This is to allow diagnostic and
adaptive tables to be stored. Disconnecting
the battery without waiting can cause
damage not covered by the vehicle
Warranty.
4. Disconnect the negative battery cable terminal.
5. Disconnect the positive battery cable terminal.
6. Remove the battery securing clamp.
7. Remove the battery.
8. To install, reverse the removal procedure.
Note: Before reconnecting the battery,
make sure the ignition remains switched off.
Note: Make sure the battery cable terminals
are fully tightened.
Note: After cleaning or replacing the
battery, make sure you reinstall the battery
cover or shield.
If you disconnect or replace the vehicle
battery, you must reset the following
features:
• Window bounce-back. See Window
Bounce-Back (page 162).
• Clock Settings.
• Pre-set radio stations.
• Steering Angle Sensor.

If you intend on parking your vehicle for an
extended period after cleaning the wheels
with a wheel cleaner, drive your vehicle for
a few minutes before parking your vehicle.
This reduces the risk of corrosion of the
brake discs, brake pads and linings.
Do not clean the wheels when they are hot.
Note:
Some car washes could damage
wheel rims and covers.
Note: Using non-recommended cleaners,
harsh cleaning products, chrome wheel
cleaners or abrasive materials could
damage wheel rims and covers.
CLEANING THE ENGINE
COMPARTMENT
Use a vacuum cleaner to remove debris
from the screen area below windshield.
Note: If you are not familiar with the parts
around the engine do not wash the engine
compartment. Avoid frequent engine
washes.
When washing the engine compartment:
• Never wash or rinse the engine while it
is hot or running.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage.
Note: If your vehicle has an engine cover
remove the cover before application of
shampoo and degreaser.
• Spray an approved engine shampoo
and degreaser on all parts that require
cleaning and rinse with water. CLEANING STRIPES OR
GRAPHICS
It is recommended to wash your vehicle by
hand however, pressure washing may be
used under the following conditions:
•
Use a spray with a 40° wide spray
angle pattern.
• Keep the nozzle at a
12 in (305 mm)
distance and 90° angle to your
vehicle's surface.
• Do not use water pressure higher than
2,000 psi (14,000 kPa)
.
• Do not use water hotter than
179°F
(82°C).
Note: Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface.
CLEANING CAMERA LENSES AND
SENSORS
We recommend that you only use
lukewarm or cold water and a soft cloth
to clean the camera lens and sensors.
Note: Do not pressure wash camera lens
and sensors.
CLEANING THE UNDERBODY
Flush the complete underside of your
vehicle frequently. Keep body and door
drain holes free from packed dirt.
Rear suspension components may require
regular cleaning with a power washer or a
thorough rinse with a strong stream of
water if the vehicle is operated in dusty or
muddy environments. Rear leaf springs or
other suspension components may emit
squeaking or popping noises while
operating the vehicle if particles, such as
dirt, rocks, or other debris, are present in
the components.

CHANGING A FLAT TIRE
If you get a flat tire when driving, do not
apply the brake heavily. Instead, gradually
decrease your speed. Hold the steering
wheel firmly and slowly move to a safe
place on the side of the road.
Have a flat serviced by an authorized
dealer to prevent damage to the system
sensors. See Tire Pressure Monitoring
System Precautions (page 560). Replace
the spare tire with a road tire as soon as
possible. When repairing or replacing the
flat tire, have the authorized dealer inspect
the system sensor for damage.
Note: The use of tire sealant could damage
your tire pressure monitoring system. Only
use in roadside emergencies.
Note: The tire pressure monitoring system
indicator light illuminates when the spare
tire is in use. To restore the full function of
the monitoring system, you must mount all
road wheels that come with tire pressure
monitoring sensors on this vehicle.
Dissimilar Spare Wheel and Tire
Assembly Information WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death.
If you have a dissimilar spare wheel and
tire, the intent of the spare wheel is for
temporary use only. This means that if you
need to use it, replace it as soon as
possible with a road wheel and tire
assembly that is the same size and type
as the road tires and wheels originally
provided by Ford. We define a dissimilar spare wheel and tire
assembly as a spare wheel and tire
assembly that is different in brand, size or
appearance from the road tires and
wheels.
Full-size dissimilar spare
When driving with the full-size dissimilar
spare wheel and tire assembly, do not:
•
Exceed
70 mph (113 km/h).
• Use more than one dissimilar spare
wheel and tire assembly at a time.
• Use snow chains on the end of the
vehicle with the dissimilar spare wheel
and tire assembly.
Engage any four-wheel drive mode. See
Four-Wheel Drive Limitations (page 292).
The usage of a full-size dissimilar spare
wheel and tire assembly can lead to
impairment of the following:
• Handling, stability and braking
performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability.
• Wet weather driving capability.
• Four-wheel drive capability.
When driving with the full-size dissimilar
spare wheel and tire assembly, give
additional caution to:
• Towing a trailer.
• Driving vehicles that come with a
camper body.
• Driving vehicles with a load on the
cargo rack.
Drive cautiously when using a full-size
dissimilar spare wheel and tire assembly
and seek service as soon as possible.
