•DEF freezes below 12°F (-11°C). Your vehicle is equipped with an
automatic pre-heating system which allows the DEF system to
operate below 12°F (-11°C).
•Do not store the DEF bottle in your vehicle. If it leaks, it could cause
damage to interior components or release an ammonia odor inside
your vehicle.
•Store DEF out of direct sunlight and in temperatures between
23°F–68°F (-5°C–20°C).
NOISE EMISSIONS
In order to keep to the federal exterior noise regulations, your vehicle
may be equipped with noise emission items. Depending on your vehicle
configuration, it may have all or some of the following items:
Air Intake System:Inspect the air cleaner. Do not alter its location. Do
not alter inlet and outlet piping.
Body:Inspect wheel well splash shields, cab shields and under hood
insulation for deterioration, dislocation and orientation.
Cooling System:
•Inspect the fan for blade damage. If you find any damage, replace
with the recommended parts. Inspect for fan-to-shroud interference
and any damage to shroud, such as cracks and holes.
•Do not change fan ratio or alter fan spacer dimensions and positions.
•Inspect fan clutch for proper operation. Make sure the fan is
disengaged when cooling of the engine is not required.
•Inspect radiator shutters (if equipped) for proper operation. The
shutters should be open during normal operating temperatures.
Engine:Valve covers and block covers damp-out engine mechanical
noise. If they need replacing, make sure to replace them with the
recommended parts. Check for mechanical isolations.
Transmission Enclosure:Inspect for cracks, holes and tears. Clean any
deposits, such as oil, dirt and stones.
Exhaust System:
•Inspect for leaks at various joint connections and loose clamps.
•
Perform a visual inspection for cracks or holes in the muffler and tail pipe.
•Always use the recommended replacement parts.
•Do not change the tail pipe elbow or offset tail pipe orientation from the
standard position as originally received.
•To avoid abnormal changes in vehicle sound levels, it is necessary for the
owner to perform inspections and necessary maintenance at the intervals
shown in theScheduled Maintenancechapter.

GENERAL INFORMATION
All standard equipment brakes self-adjusting. Automatic adjustment,
when required, occurs whenever you apply and release the brakes during
forward or reverse operation.
Note:Occasional brake noise is normal. If a metal-to-metal, continuous
grinding or continuous squeal sound is present, this may indicate worn
brake linings. Have them inspected by an authorized dealer. If your
vehicle has continuous vibration or shudder in the steering wheel while
braking, an authorized dealer should inspect the vehicle.
Know the required stopping distances for all driving conditions you may
encounter. For longer brake lining life, take full advantage of engine
braking power when coming to a stop.
WARNING:Do not drive with your foot resting on the brake
pedal. This results in abnormally high brake temperatures,
excessive lining wear and increased stopping distances.
Before descending a long or steep hill, shift to a lower gear and avoid
continuous application of the brakes. Normally, choose the same gear to
descend the hill that you use to ascend the hill.
WARNING:Continuous application of the brakes causes the
brakes to overheat, resulting in a temporary loss of braking.
See theInstrument Clusterchapter for information on the
brake system warning light.
Wet brakes result in reduced braking efficiency. Gently press the brake
pedal a few times when driving from a car wash or standing water to dry
the brakes.
If Brakes Do Not Grip Well
•If you have been driving through deep water, gently apply the brakes
several times while your vehicle is moving slowly.
•Let the brakes cool if you have been using them excessively, as in
mountain driving or after several fast, high-speed stops.
•Check brake adjustment.
•Check brake linings for excessive wear.
•Check system air pressure on vehicles equipped with air brakes.

WARNING:Do not drive or continue to drive if the low air
pressure buzzer is sounding or the brake warning light is lit.
These warnings indicate that air pressure is not to normal operating
level. Continued use of the vehicle could result in loss of braking ability.
WARNING:Avoid repeated light application of the brake pedal.
This depletes air pressure faster and could result in loss of
braking capability.
Periodically check the air pressure
gauge while driving. Pressure should
range between approximately
100–125 psi (690–862 kPa). The air
compressor governor cut-in and
cutout pressure settings are set at
the factory and are not adjustable.
When air pressure is insufficient (below 60 psi [414 kPa]), a
warning light illuminates and a buzzer sounds when the ignition
is in the on position.
This may happen because excessive brake applications are depleting the
system air pressure. If this condition occurs, stop driving your vehicle
until the compressor has fully recharged the air system.
WARNING:Do not move the vehicle when the air pressure is
insufficient because the brake system may be inoperative.
Select a gear ratio to help slow your vehicle before descending grades.
Supplementing with brakes, as required, help to safely slow the vehicle
and avoids overspeeding the engine.
Air Chamber Stroke Indication
Air chamber push rods have orange stroke indicator markers that warn
when the braking system requires adjustment or repair. The painted
orange indicator is on the air chamber push rod at the slack adjuster
stroke dimension that requires service when visible during brake
application.

OPERATING YOUR VEHICLE
General Information
•Start the vehicle moving by using the highest gear speed in the
transmission that lets the engine easily start the load without slipping
the clutch.
•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.
Driving Aids159
2015 F-650/750(f67)
Owners Guide gf(ownloose), 1st Printing, December 2013

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.

•At temperatures of –4°F (–20°C) or below, it is recommended that
you use a crankcase-mounted coolant heater to improve cold engine
starting.
•If operating in arctic temperatures of –20°F (–29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
Hot Weather
•Use a permanent-type engine coolant to protect the engine against
damage from overheating.
•Fill the fuel tank at the end of daily operation to prevent
condensation in the fuel system.
•Keep external surfaces of the engine, radiator, charge air cooler, air
conditioning condenser and accessories clean to avoid dirt build-up.
•You may experience above normal coolant temperatures while driving
in a transmission gear ratio that lugs the engine. To correct this
problem, increase engine speed by downshifting into the next lower
gear.
STEERING
Your vehicle is equipped with power steering. Power steering uses energy
from the engine to decrease the driver’s effort in steering your vehicle.
To help prevent damage to the power steering pump:
•Never hold the steering wheel to the extreme right or the extreme
left for more than a few seconds when the engine is running.
•Do not operate your vehicle with the power steering pump fluid level
below the ADD mark on the MAX COLD side of the power steering
reservoir dipstick.
•Some noise is normal during operation. If the noise is excessive,
check for low power steering pump fluid level before seeking service
by an authorized dealer.
•Low power steering pump fluid levels may cause heavy or uneven
steering efforts. Check the power steering pump fluid level before
seeking service from an authorized dealer.
•Do not fill the power steering pump reservoir above the FULL mark
on the MAX HOT side of the power steering reservoir dipstick, as this
may result in leaks from the reservoir.
If the power steering system breaks down (or if the engine is turned
off), you can steer your vehicle manually, but it takes more effort.

Do not attempt to push-start your automatic transmission vehicle.
Automatic transmissions do not have push-start capability. Attempting to
push-start a vehicle with an automatic transmission may cause
transmission damage.
Six-speed TorqShift transmissions have an adaptive shift strategy. When
you disconnect the battery or install a new battery, the automatic
transmission must relearn its shift strategy. As a result, the transmission
may have firm soft shifts, firm shifts or both. This operation is normal
and does not affect function or durability of the transmission. Over time,
the adaptive learning process fully updates transmission operation.
Preparing Your Vehicle
Note:Use only a 12–volt supply to start your vehicle.
Note:Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
1. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehicles do not touch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other
moving parts.
2. Check all battery terminals and remove any excessive corrosion
before you attach the battery cables. Make sure that vent caps are
tight and level.
3. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.
Connecting the Jumper Cables
WARNING:Do not connect the end of the second cable to the
negative (-) terminal of the battery to be jumped. A spark may
cause an explosion of the gases that surround the battery.
Note:Do not attach the negative (-) cable to fuel lines, engine rocker
covers, the intake manifold or electrical components as grounding points.
Note:In the illustration, the vehicle on the bottom is used to designate
the assisting (boosting) battery.
