2023 FORD F650/750 Owners Manual

Note:We recommend that you switch the
system off if you install a snow plow or
similar object in such a way that it may
block the radar sensor. Your vehicle
remembers the selected setting across key
cycles.
Blocked Sensors
E31E3118731873
Camera 1
Radar sensor 2If a message regarding a blocked sensor
or camera appears in the information
display, the radar signals or camera images
are obstructed. With a blocked sensor or
camera, the Pre-Collision Assist system
may not function, or performance may
reduce. The following table lists possible
causes and actions for when this message
displays.
Camera Troubleshooting
Action Cause
Clean the outside of the windshield in front
of the camera. The windshield in front of the camera is
dirty or obstructed in some way.
Wait a short time. It may take several
minutes for the camera to detect that there
is no obstruction. The windshield in front of the camera is
clean but the message remains in the
display screen.

Radar Troubleshooting
Action Cause
Clean the grille surface in front of the radar
or remove the object causing the obstruc-
tion. The surface of the radar in the grille is dirty
or obstructed in some way.
Wait a short time. It may take several
minutes for the radar to detect that there
is no obstruction. The surface of the radar in the grille is clean
but the message remains in the display
screen.
The Pre-Collision Assist system is tempor-
arily disabled. Pre-Collision Assist automat-
ically reactivates a short time after the
weather conditions improve. Heavy rain, spray, snow or fog is interfering
with the radar signals.
The Pre-Collision Assist system is tempor-
arily disabled. Pre-Collision Assist automat-
ically reactivates a short time after the
weather conditions improve. Swirling water or snow or ice on the surface
of the road may interfere with the radar
signals.
Contact an authorized dealer to have the
radar checked for proper coverage and
operation. Radar is out of alignment due to a front end
impact.
Note:Proper system operation requires a
clear view of the road by the camera. Have
any windshield damage in the area of the
camera's field of view repaired.
Note:If something hits the front end of your
vehicle or damage occurs and your vehicle
has a radar sensor, the radar sensing zone
may change. This could cause missed or
false vehicle detections. Contact an
authorized dealer to have the radar checked
for proper coverage and operation.
Note:If your vehicle detects excessive heat
at the camera or a potential misalignment
condition, a message may display in the
information display indicating temporary
sensor unavailability. When operational
conditions are correct, the message
deactivates. For example, when the ambient
temperature around the sensor decreases
or the sensor automatically recalibrates
successfully.

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.
176
Load Carrying

We do not recommend performing, or
approve of, suspension conversions.
However, we understand that, on occasion,
others install aftermarket add-on
suspensions on the truck chassis that allow
operator control for weight transfer from
other axles (such as air lift axles).

TOWING A TRAILER
WARNING: Do not exceed
the GVWR or the GAWR
specified on the certification
label.
WARNING: Towing trailers
beyond the maximum
recommended gross trailer
weight exceeds the limit of the
vehicle and could result in engine
damage, transmission damage,
structural damage, loss of
vehicle control, vehicle rollover
and personal injury.
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See Fuses
(page 200).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation.Load Placement
To help minimize how trailer
movement affects your vehicle
when driving:
• Load the heaviest items closest
to the trailer floor.
• Load the heaviest items
centered between the left and
right side trailer tires.
• Load the heaviest items above
the trailer axles or just slightly
forward toward the trailer
tongue. Do not allow the final
trailer tongue weight to go
above or below 10-15% of the
loaded trailer weight.
When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See Load Limit (page
175).
You can also find information in
the RV & Trailer Towing Guide
available at your authorized
dealer, or online.

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.
