service FORD F650/750 2023 Service Manual

Use the button on the instrument panel, in
combination with the accelerator pedal,
to maximize the use of the exhaust brake
in the following conditions:
• Off-highway driving.
• Mountain driving.
• Heavy traffic.
• High-speed highway driving.
E215226
To switch the exhaust brake on, press the
button. A light on the instrument cluster
indicates the system is on. Press the button
again to switch it off.
While approaching a steep grade, make
sure that the exhaust brake switch is on.
The exhaust brake begins working as soon
as you remove your foot from the
accelerator pedal.
Before descending a hill or steep grade,
always select the proper gear. If you take
the transmission out of gear while
descending, you may not be able to select
another gear because of maximum
governed RPM.Make sure the engine speed does not
exceed the maximum allowable engine
RPM. Exceeding the maximum allowable
engine RPM can result in damage to the
engine. Apply the service brakes to reduce
the engine RPM or make a slower descent
by using a lower gear.
While driving down a grade, use a low
enough gear to descend safely with a
minimum application of the service brakes.
As a general guideline, use the same gear
as you use to ascend the hill.
Exhaust Brake Operating
Characteristics
The exhaust brake switches on when you
remove your feet from the accelerator
pedal and the exhaust brake is on.
If the brake is working properly, you may
notice:
• A slight change in engine sound when
the exhaust brake turns on.
• A smooth braking effect. Do not expect
a retarding effect similar to sudden,
hard application of the service brakes.
• A retarding force possibly felt acting
against your body during brake
application, depending on the grade
and vehicle load. This force helps your
vehicle resist increasing speeds down
grades.
• Engine temperatures remaining in the
normal operating range.
• A drop in engine RPM, depending on
grade and vehicle load, during a
descent.
• A decrease in road speed when
applying the exhaust brake during a
descent, except when your vehicle is
carrying a heavy load or the grade is
extremely steep. In these instances,
you may need to apply the service
brakes occasionally.

Brakes

TRAILER BRAKES (IF EQUIPPED)
Trailer Brake Hand Control (If Equipped)
WARNING: The hand control
should never be used to apply the brakes
when the tractor and trailer are parked
unattended. Air may leak from the
system and the vehicle could possibly
move, resulting in possible property
damage, personal injury or death.
E210339
The hand control is located on the
right-hand side of the instrument panel. It
applies the trailer service brakes, which are
independent of the truck or tractor service
brakes.
It operates a valve that provides gradual
control of air pressure applied. When the
valve is only partially applied, you can
override the trailer brakes by pressing fully
on the brake pedal.
To apply the trailer brakes using the hand
control, move the lever downward. The
further you push the lever down, the
greater the air pressure is applied to the
brakes. The lever remains in place until
manually moved.To release the trailer brakes, move the
lever up completely.
Trailer Air Supply and Parking
Brake Modular Controls (If Equipped)
E210340
The trailer air supply valve delivers air to
the trailer supply and automatically pops
out, shutting off the trailer supply, if
pressure decreases to approximately 35 psi
(249 kPa).
E210341
The parking brake controls the spring
brakes on the tractor. When you pull the
knob out, it causes the trailer supply valve
to pop out, applying both the tractor and
trailer parking brakes. You can
independently release the trailer brakes by
pushing only the trailer air supply valve in.
145
Brakes

PRINCIPLE OF OPERATION
The traction control system helps avoid
drive wheel spin and loss of traction.
If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
Note:The system does not apply the brakes
when vehicle speed is above 25 mph
(40 km/h).
USING TRACTION CONTROL -
VEHICLES WITH: AIR BRAKES
WARNING: Operating your vehicle
with the traction control disabled could
lead to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death.
E330660E330660
Press the TCS Off button on the
instrument panel to enable the
mud/snow mode.
This is beneficial when your vehicle is stuck
in snow or on a slippery road surface. This
mode allows wheel spin to dig your vehicle
out and allows you to rock your vehicle.
Press the switch again to select standard
traction control. The system automatically
selects standard traction control at the
next ignition cycle.
System Indicator Light
Note:If the traction control light does not
flash during a traction control event or stays
illuminated, the system is not functioning
properly. Take your vehicle to an authorized
dealer for service.During traction control operation, the
traction control light flashes rapidly and
the engine does not rev-up when you press
further on the accelerator. This is normal
and is no reason for concern.
In mud/snow mode, the TCS OFF light
illuminates on the instrument cluster. If a
traction event occurs in either mode, the
stability and traction control light flashes
rapidly.
USING TRACTION CONTROL -
VEHICLES WITH: HYDRAULIC
BRAKES
WARNING: Operating your vehicle
with the traction control disabled could
lead to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death.
The system turns on each time you switch
the ignition on.
E330660E330660
Use the traction control button
on the instrument panel to
switch the system off or on.
If your vehicle is stuck in mud or snow,
switching traction control off is beneficial
as this allows the wheels to spin.
Press the button again to switch the
traction control system on.
System Indicator Light
Note:If the traction control light does not
flash during a traction control event or stays
on, the system is not operating. Have the
system checked as soon as possible.
During a traction control event, the traction
control light rapidly flashes. Pressing
further on the accelerator does not cause
the engine to rev higher. This is normal and
is no reason for concern.
149
Traction Control

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.
167
Driving Aids

• 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.
181
Towing

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.
