2021 FORD F-150 steering

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.

Note:
To calibrate the steering angle
sensor, drive the vehicle above 30 mph
(50 km/h) for a minimum of 1.2 mi (2 km).
Make sure to drive straight ahead for a
minimum of 30 seconds. Several vehicle
functions are disabled and a warning light
could appear until the sensor is calibrated.
Battery Management System
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery
drain is detected, the system temporarily
disables some of the following features:
• Heated rear window.
• Heated seats.
• Climate control.
• Heated steering wheel.
• Audio unit.
• Navigation system.
A message may appear in the information
display to alert you that battery protection
actions are active.
After battery replacement, or in some
cases after charging the battery with an
external charger, the battery management
system requires eight hours of vehicle sleep
time to relearn the battery state of charge.
During this time your vehicle must remain
fully locked with the ignition off.
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.
Battery Disposal Make sure that you dispose of
old batteries in an
environmentally friendly way.
Seek advice from your local authority
about recycling old batteries. ADJUSTING THE HEADLAMPS

•
Stand at a minimum of 12 ft
(3.66 m) away from the wheel
and tire assembly.
• Use both eye and ear
protection.
Important: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle.
It is recommended that the two
front tires or two rear tires
generally be replaced as a pair if
the worn tires still have usable
depth.
To avoid potential Four-Wheel
Drive (4WD) malfunction or
(4WD) system damage, it is
recommended to replace all four
tires rather than mixing
significantly worn tires with new
tires.
The tire pressure sensors mounted
in the wheels (originally installed
on your vehicle) are not designed
to be used in aftermarket wheels.
The use of wheels or tires not
recommended may affect the
operation of your tire pressure
monitoring system.
If the tire pressure monitoring
system indicator is flashing, your
system is malfunctioning. Your
replacement tire might be
incompatible with your tire
pressure monitoring system, or
some component of the system
may be damaged. USING SNOW CHAINS WARNING: Do not exceed 30 mph
(50 km/h)
. Failure to follow this
instruction could result in the loss of
control of your vehicle, personal injury or
death. WARNING:
Do not use snow chains
on snow-free roads. WARNING:
Only fit snow chains to
specified tires. WARNING:
If your vehicle is fitted
with wheel trims, remove them before
fitting snow chains. WARNING: If you choose to install
snow tires on your vehicle, they must be
the same size, construction, and load
range as the original tires listed on the
tire placard, and they must be installed
on all four wheels. Mixing tires of
different size or construction on your
vehicle can adversely affect your
vehicle's handling and braking, and may
lead to loss of vehicle control. WARNING:
Wheels and tires must
be the same size, load index and speed
rating as those originally fitted on the
vehicle. Use of any other tire or wheel
can affect the safety and performance
of your vehicle. Additionally, the use of
non-recommended tires and wheels can
cause steering, suspension, axle, transfer
case or power transfer unit failure.
Follow the recommended tire inflation
pressures found on the Safety
Compliance Certification label, or the
Tire Label on the B-Pillar or the edge of
the driver door. Failure to follow this
instruction could result in loss of vehicle
control, vehicle rollover, or personal injury
or death.

Your vehicle comes with high performance,
all-terrain tires designed to optimize
handling, steering and braking to provide
the performance you expect in a Ford
Performance vehicle. These tires are
optimized for both on and off-road
performance, and their ride, noise and wear
characteristics are different from other
tires. Also, because of their aggressive
tread profile, it is important that you
maintain your tires properly.
•
Always maintain your tire pressures
according to the tire information
placard located on the driver ’s door
B-pillar, using an accurate gauge.
Remember to be prepared to re-inflate
your tires before returning to the road.
If a tire filling station is not available,
remember to prepare a supplemental
means to inflate the tires, such as a
portable compressor.
• Check and set the tire pressures when
the tires are cold, and not warm from
driving. Wait at least three hours after
parking the vehicle before checking tire
pressure. Do not reduce the pressure
of warm tires.
• Check your tire pressure often to
maintain it properly. Tire pressure can
decrease over time and fluctuate with
temperature.
• Do not overload your vehicle.
Maximum vehicle and axle weights are
on the tire information placard.
• Use extra caution when operating the
vehicle near its maximum load,
including assuring proper tire pressure
and reducing speeds.
• If you encounter an abnormally harsh
impact, inspect your tires for damage.
• Inspect your tires for damage on a
regular basis. Replace a damaged tire
immediately. •
We do not approve the use of snow
chains on your vehicle's tires.
• Proper suspension alignment is critical
for maximum performance and
optimal tire wear. If you notice uneven
tire wear, have your alignment checked.
Spare Tire and Wheel
Your vehicle comes with a full size
matching spare with an all-terrain tire. The
spare tire and wheel assembly has the
same capability as the road tire and wheel
assemblies but does not come with a tire
pressure monitoring sensor. Wheels
