2023 FORD F650/750 wheel

Why is the feature not available (line markings are gray) when I can see the lane markings
on the road?
There is standing water on the road.
Faint lane markings, for example partial yellow lane markings on concrete roads.
Lane width is too narrow or too wide.
The camera has not been calibrated after a windshield replacement.
Driving on tight roads or on uneven roads.
Vehicle accessories are blocking the camera, for example a snow plow.
STEERING
Hydraulic Power Steering
To help prevent damage to the power
steering system:
• Do not hold the steering wheel at its
furthest turning points for more than
three to five seconds when the engine
is running.
• Avoid continuously steering back and
forth with elevated engine RPM as this
may overheat the system. If trying to
free a stuck vehicle, pause between
attempts to allow the power steering
system to cool or seek assistance.
Typical steering and driving maneuvers
allow the system to cool.
• Do not operate the vehicle if the power
steering pump fluid level is below the
MIN mark on the reservoir.
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
If the power steering system breaks down
or if you switch the engine off, you can
steer the vehicle manually, but it takes
more effort.
If you have any steering components
serviced or replaced, install new fasteners.
Many fasteners have coatings with thread
adhesive, or have prevailing torque
features you cannot reuse. Do not reuse a
bolt or nut. Torque fasteners to
specifications.
Steering Tips
If the steering wanders or pulls, check for:
• An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.

LOAD LIMIT
WARNING: Do not exceed
the GVWR or the GAWR
specified on the Safety
Compliance Certification Label.
WARNING: Do not use
replacement tires with lower
load carrying capacities than the
original tires because they may
lower the vehicle's GVWR and
GAWR limitations. Replacement
tires with a higher limit than the
originals do not increase the
GVWR and GAWR limitations.
WARNING: Exceeding any
vehicle weight rating limitation
could result in serious damage
to the vehicle and/or personal
injury.
Every vehicle manufactured by
Ford Motor Company is supplied
with information on the Safety
Compliance Certification Label,
located on either the B-pillar or
the driver’s door edge, listing the
maximum loading for the vehicle
(GVWR), and its axle systems
(GAWR) at the tire to ground
interface.
Example only:
E210937
Under no circumstances should
your vehicle be loaded in excess
of the GVWR or GAWR. It is the
operator’s responsibility to ensure
that neither the axle capacities,
spring capacities, tire capacities
nor the vehicle rated GVWR is
exceeded.
Unloaded or Lightly Loaded
Vehicles
WARNING: When
operating empty or lightly
loaded, sudden or hard braking
may induce wheel lockup with
loss of vehicle control and the
possibility of accident and
serious injury, especially on wet
or slippery road surfaces.
The braking system has been
designed to safely stop your
vehicle when fully loaded to its
GVWR.

Load Carrying

AIR SUSPENSION
Note:Do not operate your vehicle without
air in the suspension springs. Operating your
vehicle without air in the suspension springs
damages the suspension, degrades ride
performance and may cause property
damage.
The air suspension system automatically
adjusts to different loads to maintain a
constant frame height, allows for ease of
vehicle loading, provides improved vehicle
ride, and increased driver comfort.
Air Suspension Dump Button
E213409
Note:The suspension dumps air when the
ignition is in the accessory or on position,
but fills only when the ignition is in the on
position.
A button located on the instrument panel
controls the system. It operates only when
the ignition is in the accessory or on
position and the air tanks have sufficient
pressure to fill the air springs. When you
turn off the ignition, the suspension
remains in whatever state it was last set.
Pressing and holding the button for two
seconds exhausts air from the air springs,
lowering the frame for loading. Pressing
and holding the button for two seconds
fills the air springs so your vehicle remains
at normal ride height.
System Indicator Light
The air suspension indicator light
illuminates when using the button to
release air pressure in the rear air springs.
Never drive your vehicle when the warning
lamp is illuminated and there is low (or no)
air pressure in the springs.
Connecting and Disconnecting a
Trailer with Air Suspension and Air
Suspension Dump Button
When connecting to a trailer:
• Press and hold the button for two
seconds to exhaust air from the air
suspension system.
• Press and hold the button for two
seconds, and then raise the landing
gear after making the connection to
the trailer.
When disconnecting the trailer:
• Lower the landing gear, and then press
and hold the button for two seconds.
• Disconnect the brake hoses, trailer-side
and rear light connectors, then pull the
release lever on the fifth wheel.
You must fill the air springs before
operating with a trailer or operating in the
bobtail mode.
Suspension Conversions
WARNING: When operating a
loaded vehicle, the driver must keep all
adjustable axles on the ground at all
times, supporting their share of the
vehicle’s load. Failure to do so can
overload other axles, tires, wheels,
springs, steering components, brakes
and frames, resulting in early component
failure, loss of vehicle control, possible
property damage and personal injury.

Load Carrying

ESSENTIAL TOWING CHECKS
See Load limits in the Load Carrying
chapter for load specification terms found
on the tire label and Safety Compliance
label and instructions on calculating your
vehicle's load.
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle. You
must distribute the load in your trailer so
that 10-15% of the total weight of the
trailer is on the tongue.
Safety Chains
Note:Do not attach safety chains to the
bumper.
Always connect the safety chains to the
frame or hook retainers of your vehicle
hitch.
To connect the safety chains, cross the
chains under the trailer tongue and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground.
Trailer Brakes
WARNING: Do not connect a
trailer's hydraulic brake system directly
to your vehicle's brake system. Your
vehicle may not have enough braking
power and your chances of having a
collision greatly increase.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Trailer Lamps
WARNING: Never connect any
trailer lamp wiring to the vehicle's tail
lamp wiring; this may damage the
electrical system resulting in fire. Contact
your authorized dealer as soon as
possible for assistance in proper trailer
tow wiring installation. Additional
electrical equipment may be required.
Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 mph
(80 km/h).
• When stopped in congested or heavy
traffic during hot weather, place the
transmission in park (P) or neutral (N)
to aid engine and transmission cooling
and to help air conditioning
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
180
Towing

• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with
the Tow/Haul feature, use this feature
when towing. This provides engine
braking and helps eliminate excessive
transmission shifting for optimum fuel
economy and transmission cooling.
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
FIFTH WHEEL OPERATION
WARNING: Failure to follow the
fifth wheel manufacturer’s instructions
for hooking and unhooking as well as
sliding the fifth wheel could result in an
accident, personal injury or death.
WARNING: When the tractor and
trailer are parked unattended, the trailer
brake hand control should never be used
to apply the brake, since air may leak
from the system, allowing vehicle
movement, resulting in possible property
damage, personal injury or death.
Before hook-up, make sure:
• The fifth wheel jaws are fully open.
• The fifth wheel is fully tilted back to
prevent body damage when the tractor
is backed under a trailer.
• You block the trailer wheels and adjust
and apply the trailer spring brakes.
Never chase a trailer.
• The brake hoses and light cords are
clear of the fifth wheel.
Hook-up
1. Back the tractor squarely under the
trailer, engaging the fifth-wheel jaws
on the kingpin. Always back up slowly;
make sure the trailer is neither too high
nor too low. Avoid backing under the
trailer from an angle.
2. Connect the service and emergency
brake hoses and trailer light connector.
3. Inspect the jaws of the fifth wheel to
be sure they have fully closed on the
trailer kingpin and the trailer plate is
resting securely on the fifth wheel.
4. Make sure the coupler release lever is
in the locked position.
5. Charge the trailer brake system. Set
the trailer brakes, with either the hand
valve or tractor protection valve. Pull
against the trailer for an extra check of
proper hook-up. Do not pull hard
enough to damage or strain the
equipment.
6. Set the tractor parking brakes and fully
raise the trailer landing gear.
7. Check the operation of all trailer lights
and correct any lights that may be
faulty.
Un-hook
1. Try to keep the tractor and trailer in a
straight line.
2. Apply the parking brakes.
3. Lower the trailer landing gear, making
sure it is on solid, level ground. The
weight of the trailer is to be on the
landing gear.
4. Block the trailer wheels.
5. Disconnect the brake hoses and light
cords. Be sure hoses and cords are
clear.
6. Pull coupler release lever to disengage
the fifth wheel jaws.

GENERAL DRIVING POINTS
General Information
• Accelerate smoothly and evenly. Rapid
acceleration increases fuel
consumption without increasing engine
performance.
• When approaching a hill, press the
accelerator smoothly to start the
incline at full power, and then shift
down as needed to maintain vehicle
speed.
• When going down a hill, or long steep
grades, prevent overspeeding of the
engine. Normally, choose the same
gear to descend the hill that you use to
ascend the hill. The engine governor
has no control over engine speed when
it is being pushed by a loaded vehicle.
• Do not operate in a gear that permits
an engine speed more than the
maximum governed speed or high-idle
RPM (no load).
• Always shift to a lower gear at high
altitudes to prevent engine smoking.
Backing Up
WARNING: All vehicles have blind
spots. To reduce the risk of severe injury
or property damage, never move your
vehicle to the side or rear or change lanes
without being sure your way is clear on
both sides and to your rear.
WARNING: To reduce the risk of
the possibility of personal injury while
backing up the vehicle, always be sure
your vehicle’s path is clear.Before backing up your vehicle, be sure you
can do so safely. If anything behind the cab
limits your view, do not rely on mirrors
alone to make sure that your intended path
is clear. If other people are in the vicinity,
have someone standing well behind your
vehicle and outside of your intended path
(visible through an exterior mirror) guide
you as you back up.
Although OSHA or some governmental
regulations may require the use of an
electrical or mechanical back up alarm to
warn bystanders, such an alarm does not
guarantee that the intended path is clear.
When in doubt, get out of your vehicle and
visually check the intended path is clear.
Back up slowly as to allow others time to
move, if necessary.
If you install an electrical back up alarm,
connect it to the backup lamp circuit.
Parking
WARNING: When parking your
vehicle, do not leave the transmission in
gear; if the key is in the on position and
the vehicle rolls, the engine could start.
Failure to follow these instructions could
result in an unattended vehicle moving,
possibly causing personal injury or
property damage.
Always use the parking brake. When
parking on a grade, block the wheels and
turn the front wheels to one side so that if
your vehicle rolls, the front tires act against
the curb to stop your vehicle. The front
wheels are more effective at stopping a
rolling vehicle than the rear wheels.

Driving Hints

ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds. Traveling
at 55 mph (90 km/h) uses 15% less
fuel than traveling at 65 mph
(105 km/h).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.
• Carry unnecessary weight.
Approximately 1 mpg [0.4 km/L] is lost
for every 400 lb (180 kg) of weight
carried.
• Driving with the wheels out of
alignment.Conditions
• Adding certain accessories to your
vehicle may reduce fuel economy. For
example bug deflectors, rollbars, light
bars, running boards, ski racks or
luggage racks.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 5–10 mi
(12–16 km) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
COLD WEATHER
PRECAUTIONS
Note:Idling in cold weather does not heat
the engine to its normal operating
temperature. Long periods of idling,
especially in cold weather, can cause a
buildup of deposits which can cause engine
damage.
Changing to a lighter grade engine oil also
makes starting easier under these
conditions. Refer to Engine oil
specifications. See Engine Oil Capacity
and Specification (page 292).
Diesel fuel is adjusted seasonally for cold
temperatures. Diesel fuel which has not
been properly formulated for the ambient
conditions may gel which can clog the fuel
filters. One indication that the fuel filter(s)
may be clogged is if the engine starts, stalls
after a short time, and then does not
restart. If you have been using biodiesel,
you may need to use a fuel with lower
biodiesel content, try another brand, or
discontinue using biodiesel. Do not use
184
Driving Hints

Avoid driving too fast during the first
1,000 mi (1,600 km). Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Drive your new vehicle at least 1,000 mi
(1,600 km) before towing a trailer. Make
sure you use the specified engine oil. See
Engine Oil Capacity and Specification
(page 292).
Do not add friction modifier compounds
or special break-in oils during the first few
thousand miles (kilometers) of operation.
These additives may prevent piston ring
seating.
DRIVING THROUGH WATER
WARNING: Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note:Driving through standing water can
cause vehicle damage.
Note:Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs.
E176913E176913
When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
• Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
Operation in Standing Water
Ingestion of water into the diesel engine
can result in immediate and severe
damage to the engine. If driving through
water, slow down to avoid splashing water
into the intake. If the engine stalls, and you
suspect ingestion of water into the engine,
do not try to restart the engine. Consult
your dealer for service immediately.
Your fuel tank vents to the atmosphere by
valves on top of the tank and through the
fuel cap. If water reaches the top of the
tank, the valves may pull water into the
fuel tank. Water in the fuel can cause
performance issues and damage the fuel
injection system.
