2023 FORD F650/750 clock

5. Turn the air conditioning (if equipped)
on and allow the engine to idle for at
least one minute.
6. Release the parking brake. With your
foot on the brake pedal and with the
air conditioning on, put the vehicle in
drive (D) and allow the engine to idle
for at least one minute.
• If you do not allow the engine to
relearn its idle trim, the idle quality
of your vehicle may be adversely
affected until the idle trim is
eventually relearned.
7. Drive the vehicle to complete the
relearning process
• The vehicle may need to be driven
10 mi (16 km) or more to relearn the
idle and fuel trim strategy along
with the ethanol content for flexible
fuel vehicles.
If the battery has been disconnected or a
new battery has been installed, the clock
and radio settings must be reset once the
battery is reconnected.
Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized standards
for disposal. Call your local authorized
recycling center to find out more about
recycling automotive batteries.
Battery Management System (If
Equipped)
The battery management system (BMS)
monitors battery conditions and takes
actions to extend battery life. If excessive
battery drain is detected, the system may
temporarily disable certain electrical
features to protect the battery. Those
electrical accessories affected include the
rear defrost, heated/cooled seats, climate
control fan, heated steering wheel, audio
and navigation system. A message may be
shown in the information displays to alertthe driver that battery protection actions
are active. These messages are only for
notification that an action is taking place,
and not intended to indicate an electrical
problem or that the battery requires
replacement.
Electrical accessory installation
To ensure proper operation of the BMS,
any electrical devices that are added to
the vehicle should not have their ground
connection made directly at the negative
battery post. A connection at the negative
battery post can cause inaccurate
measurements of the battery condition
and potential incorrect system operation.
Note:Electrical or electronic accessories
added to the vehicle by the dealer or the
owner may adversely affect battery
performance and durability, and may also
affect the performance of other electrical
systems in the vehicle.
When a battery replacement is required,
the battery should only be replaced with
a Ford recommended replacement battery
which matches the electrical requirements
of the vehicle. After battery replacement,
or in some cases after charging the battery
with the external charger, the BMS requires
eight hours of vehicle sleep time (key off
with doors closed) to relearn the new
battery state of charge. Prior to relearning
the state of charge, the BMS may disable
electrical features (to protect the battery)
earlier than normal.
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, the
alignment of your headlamps should be
checked by your authorized dealer.

Vertical Aim Adjustment Procedure
1. Park the vehicle directly in front of a
wall or screen on a level surface,
approximately 25 ft (7.6 m) away.
2. Measure the height of the headlamp
bulb center from the ground and mark
an 8 ft (2.4 m) horizontal reference line
on the vertical wall or screen at this
height.
Note:To see a clearer light pattern for
adjusting, you may want to block the light
from one headlamp while adjusting the
other.
3. Turn on the low beam headlamps to
illuminate the wall or screen and open
the hood.
E142465
4. On the wall or screen you will observe
a flat zone of high intensity light
located at the top of the right hand
portion of the beam pattern. If the top
edge of the high intensity light zone is
not at the horizontal reference line, the
headlamp will need to be adjusted.

5. Locate the vertical adjuster on each
headlamp. Using a Phillips #2
screwdriver, turn the adjuster either
clockwise or counterclockwise in order
to adjust the vertical aim of the
headlamp.
6. Repeat Steps 3 thru 5 to adjust the
other headlamp.
7. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.

Maintenance

Note:Make sure that the wiper blade locks
into place. Lower the wiper arm and blade
back on the windshield. The wiper arms will
automatically return to their normal position
when you turn the ignition on.
• Replace wiper blades at least once per
year for optimum performance.
• You can improve poor wiper quality by
cleaning the wiper blades and the
windshield.
REMOVING A HEADLAMP
E163822
1. Remove the four bolts from the
headlamp assembly.
2. Pull the assembly straight out
disengaging one snap clip from the
fender.
3. Disconnect the electrical connector by
squeezing the release tab and pushing
the connector forward, then pulling it
rearward.
CHANGING A BULB
WARNING: Bulbs can become hot.
Let the bulb cool down before removing
it. Failure to do so could result in
personal injury.Headlamp bulbs must be marked with an
authorized D.O.T. marking for North
America to make sure they have the proper
lamp performance, light brightness, light
pattern and safe visibility.
Install in the reverse order unless otherwise
stated.
Headlamp Bulbs
1. Switch all of the lamps and the ignition
off.
2. Remove the headlamp. See
Removing a Headlamp (page 250).
3. Release the clip and remove the bulb.

2. Install the lower portion of the housing
on the top portion. Tighten by hand
until you feel a strong resistance.
Continue to tighten with a 32mm
socket wrench until the mechanical
stop on the bottom meets the top.
3. Connect the electrical connector.

Repeat this operation six times in a row
to purge any trapped air from the fuel
system.
Engine-mounted Fuel Filter
Although the fuel system is not fully
pressurized when the vehicle is off, some
residual pressure may remain in the fuel
system since it can take some time for the
pressure to completely bleed off.
Therefore, we recommend you place an
absorbent cloth below the filter connectors
to absorb any fuel that may drain.
The engine-mounted fuel filter is a plastic
disposable cartridge.Removal

Maintenance

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.
Note:Passengers should not remain in the
vehicle when the vehicle is being jacked.
Park on a level surface, set the parking
brake and activate the hazard flashers.
1. Turn the engine off and block the wheel
that is diagonally opposite of the flat
tire using a wheel chock.
2. Loosen each wheel lug nut ½ turn
counterclockwise, but do not remove
them until the wheel is raised off the
ground.
3. Replace the flat tire with the spare tire,
making sure the valve stem is facing
outward on all front and inboard rear
wheels. If you are replacing the
outboard wheel, the valve stem must
be facing inward. Reinstall the lug nuts
until the wheel is snug against the hub.
Do not fully tighten the lug nuts until
the wheel has been lowered.4. Lower the wheel and fully tighten the
lug nuts in the order shown below. See
Technical Specifications (page 286).
5. Unblock the wheels.
