2015 FORD F750 brake

PRINCIPLES 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 rear 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
WARNING:Aggressive driving in any road conditions can cause
you to lose control of your vehicle increasing the risk of severe
personal injury or property damage. The occurrence of a traction
control event is an indication that at least some of the tires have
exceeded their ability to grip the road; this may lead to an increased
risk of loss of vehicle control, vehicle rollover, personal injury and
death. If you experience a severe road event, SLOW DOWN.
Press the switch to select Off Road
or Mud/Snow traction mode. This is
beneficial when your vehicle is
stuck in snow or on a slippery road
surface. This mode allows excess
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.

PRINCIPLES OF OPERATION
Cruise control lets you maintain a set speed without keeping your foot
on the accelerator pedal.
USING CRUISE CONTROL
WARNING:Do not use cruise control in heavy traffic, on
winding roads or when the road surface is slippery. This could
result in loss of vehicle control, serious injury or death.
WARNING:When you are going downhill, your vehicle speed
may increase above the set speed. The system will not apply the
brakes. Change down a gear to assist the system in maintaining the set
speed. Failure to do so could result in loss of vehicle control, serious
injury or death.
Note:Cruise control disengages if your vehicle speed decreases more
than 10 mph (16 km/h) below your set speed while driving uphill.
The cruise controls are located on
the steering wheel.

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.
Cold Weather
Note:Idling in cold weather does not heat the engine to its normal
operating temperature. Long periods of idling in cold weather can cause
a build-up of heavy deposits of carbon and rust on valve stems causing
them to stick which, in turn, can cause valvetrain damage.
Note:We recommend against using winter fronts, or other air-restrictive
devices mounted in front of the radiator on vehicles with
chassis-mounted charge air coolers, unless extremely cold weather
conditions exist. Airflow restriction can cause high exhaust temperatures,
power loss, excessive fan usage and a reduction in fuel economy. If you
must use a winter front, the device should have a permanent opening of
at least 120 square inches (774 square centimeters) directly in line with
the fan hub.
For best engine operation in temperatures of 32°F (0°C) or lower:
•Make sure the batteries are the correct type and are fully charged.
Check other electrical components to make sure they are in optimum
condition.
•Use a permanent-type engine coolant to protect the engine against
damage from freezing.
•If your vehicle is equipped with a water-fuel separator, drain it daily.
Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Use the proper engine oil and maintain it at its proper level.

Connecting and Disconnecting a Trailer with Air Suspension and
Air Suspension Dump Switch
When connecting to a trailer:
•Press the lower portion of the switch to exhaust air from the air
suspension system.
•Press the upper portion of the switch, and then raise the landing gear
after making the connection to the trailer.
When disconnecting the trailer:
•Lower the landing gear, and then press the lower portion of the
switch.
•Disconnect the brake hoses, trailer-side and rear light connectors,
then pull the release lever on the fifth wheel.
You must press the upper portion of the switch 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.
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’s load capacity designation is by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Second-unit bodies are not included in maximum trailer weight ratings.
You must subtract the weight of the extra body from the maximum
trailer weight.
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.

Safety Chains
Note:Do not attach safety chains to the bumper.
Always connect the trailer’s safety chains to the frame or hook retainers
of your vehicle hitch.
To connect the trailer’s 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 crash 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 a fire. Contact an 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 miles (80 kilometers).

•Place the gearshift lever in positionP(if equipped) or neutral to aid
in engine and transmission cooling and air conditioning efficiency
during hot weather while stopped in traffic.
•Turn off the speed control. The speed control may turn off
automatically when you are towing on long, steep grades.
•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.
•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.
