engine FORD SUPER DUTY 2021 Owners Manual

Engine
•
Change the engine oil and filter prior to
storage because used engine oil
contains contaminates which may
cause engine damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast
idle with the climate controls set to
defrost until the engine reaches normal
operating temperature.
• With your foot on the brake, shift
through all the gears while the engine
is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel system
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
Cooling system
• Protect against freezing temperatures.
• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling
system leaks and that fluid is at the
recommended level.
Disconnecting Your 12 Volt Battery
• Check and recharge as necessary. Keep
connections clean.
• If storing your vehicle for more than 30
days without recharging the battery,
we recommend that you disconnect
the battery cables to maintain battery
charge for quick starting.
Note: It is necessary to reset memory
features if you disconnect the battery
cables. Brakes
•
Make sure the brakes and parking brake
release fully.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected
during storage such as mice or squirrel
nests.
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label.
• Check brake pedal operation. Drive
your vehicle
15 ft (4.5 m) back and
forth to remove rust build-up.
• Check fluid levels (including coolant,
oil and gas) to make sure there are no
leaks, and fluids are at recommended
levels.
• If you remove the battery, clean the
battery cable ends and check for
damage.

•
To reduce the chances of interference
from another vehicle, perform the
system reset procedure at least 3 ft
(1 m) 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 can time-out and you have
to repeat the entire procedure on all
four wheels.
• A double horn sounds indicating the
need to repeat the procedure.
Performing the System Reset Procedure
- Single Rear Wheel
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 you successfully
enter the reset mode, the horn sounds
once, the system indicator flashes and
a message shows 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 shows 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 side front tire, Right front -
passenger side front tire, Right rear -
passenger side rear tire, Left rear -
driver 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 tone 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
side rear tire, the system indicator
stops flashing, and a message shows
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.

WARNING: To help prevent your
vehicle from moving when changing a
wheel, shift the transmission into park
(P), set the parking brake and use an
appropriate block or wheel chock to
secure the wheel diagonally opposite to
the wheel being changed. For example,
when changing the front left wheel,
place an appropriate block or wheel
chock on the right rear wheel. WARNING:
Always use the jack
provided as original equipment with your
vehicle. If using a jack other than the one
provided, make sure the jack capacity is
adequate for the vehicle weight,
including any vehicle cargo or
modifications. If you are unsure if the jack
capacity is adequate, contact the
authorized dealer. WARNING:
Failure to follow these
guidelines could result in an increased
risk of loss of vehicle control, injury or
death. WARNING:
Never place anything
between the vehicle jack and your
vehicle. WARNING:
Never place anything
between the vehicle jack and the ground. WARNING:
Park your vehicle so
that you do not obstruct the flow of
traffic or place yourself in any danger and
set up a warning triangle. WARNING:
Do not work on your
vehicle when the jack is the only support
as your vehicle could slip off the jack.
Failure to follow this instruction could
result in personal injury or death. WARNING:
Do not get under a
vehicle that is only supported by a
vehicle jack. WARNING:
Do not attempt to
change a tire on the side of the vehicle
close to moving traffic. Pull far enough
off the road to avoid the danger of being
hit when operating the jack or changing
the wheel. WARNING:
Only use the spare
wheel carrier to stow the wheel provided
with your vehicle. Other wheel sizes
could cause the spare wheel carrier to
fail if it does not fit securely or is too
heavy.
Note: Do not use impact tools or power
tools operating at over 200 RPM on the
spare wheel carrier winch, which may cause
it to malfunction and prevent a secure fit.
Override the winch at least three times
(there is an audible click each time) to make
sure the wheel and tire fit securely.
Note: Passengers should not remain in the
vehicle when the vehicle is being jacked.
1. Park the vehicle on a level firm ground and activate the hazard flashers.
2. Apply the parking brake, place the transmission in park (P), switch the
engine off.
3. Block the wheel diagonally opposite the flat tire. For example, if the left
front tire is flat, block the right rear
wheel.
