Ford F-650/750 (2018 year). Manual — part 51

Note: Electrical or electronic accessories
or components added to the vehicle by the
dealer or the owner may adversely affect
battery performance and durability.

Your vehicle is equipped with a Motorcraft
maintenance-free battery which normally
does not require additional water during
its life of service.

For longer, trouble-free operation, keep the
top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.

If you see any corrosion 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.

It is recommended that the negative
battery cable terminal be disconnected
from the battery if you plan to store your
vehicle for an extended period of time.

Because your vehicle’s engine is
electronically controlled by a computer,
some control conditions are maintained
by power from the battery. When the
battery is disconnected or a new battery
is installed, the engine must relearn its idle
and fuel trim strategy for optimum
driveability and performance. To begin this
process

1.

With the vehicle at a complete stop,
set the parking brake.

2. Put the gearshift in park (P) or neutral

(N) and turn off all accessories.

3. Start the engine. Run the engine until

it reaches normal operating
temperature.

4. Allow the engine to idle for at least one

minute.

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 alert

the 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.

CHECKING THE WIPER
BLADES

E142463

Run the tip of your fingers over the edge of
the blade to check for roughness.

Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.

CHANGING THE WIPER
BLADES

You can manually move the wiper arms
when the ignition is off. This allows for ease
of blade replacement and cleaning under
the blades.

E165804

1.

Pull the wiper blade and arm away
from the glass.

A

E165794

2. Release the wiper blade lock (A) and

separate the wiper blade from the
wiper arm.

3. Install in the reverse order.

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.

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.

Headlamp Aiming Target

8 feet (2.4 meters)

A

Center height of lamp to ground

B

25 feet (7.6 meters)

C

Horizontal reference line

D

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.

E163806

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.

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.
