DRAINING THE FUEL FILTER
WATER TRAP - DIESEL WARNING: Do not drain the
water-in-fuel separator while the engine
is running. Failure to follow this warning
may result in fire, serious injury, death or
property damage. WARNING:
Do not dispose of fuel
in the household refuse or the public
sewage system. Use an authorized waste
disposal facility.
Your vehicle's fuel system has a fuel filter
and water separator to remove water from
the fuel.
If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator.
Note: Allowing water to stay in the fuel
system after the water in fuel indicator
illuminates could result in extensive damage
or failure of the fuel injection system. The fuel water trap is above the frame rail
under the driver side of the vehicle.
Make sure the ignition is off before
performing the following steps.

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.

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

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
Vertical Aim Adjustment
The headlamps on your vehicle are
properly aimed at the assembly plant. If
your vehicle has been in an accident,
contact an authorized dealer to check and
realign your headlamps.

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:
•
