Ford Super Duty (2018 year). Manual — part 74

BREAKING-IN

You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.

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
Capacities and Specifications (page
428).

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.

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.

•

Combine errands and minimize
stop-and-go driving.

•

Close the windows for high-speed
driving.

•

Drive at reasonable speeds (traveling
at 55 mph [88 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.

•

Revving the engine before turning it off.

•

Idle for periods longer than one minute.

•

Warm up your vehicle on cold
mornings.

•

Use the air conditioner or front
defroster.

•

Use the speed control in hilly terrain.

•

Rest your foot on the brake pedal while
driving.

•

Drive a heavily loaded vehicle or tow a
trailer.

•

Carry unnecessary weight
(approximately 1 mpg [0.4 km/L] is
lost for every 400 lb [180 kilogram] of
weight carried).

•

Driving with the wheels out of
alignment.

Conditions
•

Heavily loading a vehicle or towing a
trailer may reduce fuel economy at any
speed.

•

Adding certain accessories to your
vehicle (for example bug deflectors,
rollbars, light bars, running boards, ski
racks or luggage racks) may reduce
fuel economy.

•

To maximize the fuel economy, drive
with the tonneau cover installed (if
equipped).

•

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.

•

Four-wheel-drive operation (if
equipped) is less fuel efficient than
two-wheel-drive operation.

•

Close the windows for high-speed
driving.

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.

E176913

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.

FLOOR MATS

WARNINGS

Use a floor mat designed to fit the
footwell of your vehicle that does not
obstruct the pedal area. Failure to

follow this instruction could result in the
loss of control of your vehicle, personal
injury or death.

Pedals that cannot move freely can
cause loss of vehicle control and
increase the risk of serious personal

injury.

Secure the floor mat to both
retention devices so that it cannot
slip out of position and interfere with

the pedals. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death.

Do not place additional floor mats
or any other covering on top of the
original floor mats. This could result

in the floor mat interfering with the
operation of the pedals. Failure to follow
this instruction could result in the loss of
control of your vehicle, personal injury or
death.

Always make sure that objects
cannot fall into the driver foot well
while your vehicle is moving. Objects

that are loose can become trapped under
the pedals causing a loss of vehicle control.

E142666

To install the floor mats, position the floor
mat eyelet over the retention post and
press down to lock in position.

To remove the floor mat, reverse the
installation procedure.

Note: Regularly check the floor mats to
make sure they are secure.

SNOWPLOWING

Ford recommends that the Super Duty
F-Series used for snow removal include
the snowplow package option.

Installing the Snowplow

Weight limits and guidelines for selecting
and installing the snowplow are in the Ford
Truck Body Builders Layout Book,
snowplow section, found at
www.fleet.ford.com/truckbbas. A typical
installation affects the following:

•

Certification to government safety laws
such as occupant protection and airbag
deployment, braking, and lighting. Look
for an Alterer’s Label on the vehicle
from the snowplow installer certifying
that the installation meets all
applicable Federal Motor Vehicle
Safety Standards (FMVSS).

•

The Total Accessory Reserve Capacity
(TARC) is on the lower right side of the
vehicle’s Safety Compliance
Certification Label. This applies to
Ford-completed vehicles of 10,000 lb
(4,536 kg) GVWR or less. This is the
weight of permanently-attached
auxiliary equipment, such as snowplow
frame-mounting hardware, that can
be added to the vehicle and satisfy
Ford compliance certification to
FMVSS. Exceeding this weight may
require the auxiliary equipment installer
additional safety certification
responsibility. The Front Accessory
Reserve Capacity (FARC) is for
customer convenience.

•

Rear ballast weight behind the rear
axle may be required to prevent
exceeding the FGAWR, and provide
front-to-rear weight balance for proper
braking and steering.

•

Front wheel toe may require
re-adjustment to prevent premature
uneven tire wear. Specifications are in
the Ford Workshop Manual.

•

Headlight aim may require
re-adjustment.

•

The tire air pressures recommended
for general driving are on the vehicle’s
Safety Certification Label. The
maximum cold inflation pressure for
the tire and associated load rating is
on the tire sidewall. Tire air pressure
may require re-adjustment within these
pressure limits to accommodate the
additional weight of the snowplow
installation.

•

Federal and some local regulations
require additional exterior lamps for
snowplow-equipped vehicles. Consult
your authorized dealer for additional
information.

Operating the Vehicle with the
Snowplow Attached

Note: Do not use your vehicle for snow
removal until you have driven at least
500 mi (800 km).

Ford recommends vehicle speed does not
exceed 45 mph (72 km/h) when
snowplowing.

The attached snowplow blade restricts
airflow to the radiator, and may cause the
engine to run at a higher temperature:
Attention to engine temperature is
especially important when outside
temperatures are above freezing. Angle
the blade to maximize airflow to the
radiator and monitor engine temperature
to determine whether a left or right angle
provides the best performance.

Follow the severe duty schedule in your
Scheduled Maintenance information for
engine oil and transmission fluid change
intervals.

Snowplowing with your Airbag
Equipped Vehicle

WARNINGS

Do not attempt to service, repair, or
modify the airbag supplemental
restraint system (SRS) or its fuses.

Contact an authorized dealer.

Additional equipment for example
snowplow equipment may affect the
performance of the airbag sensors

increasing the risk of injury. Please refer to
the Body Builders Layout Book for
instructions about the appropriate
installation of additional equipment.

All occupants of the vehicle,
including the driver, should always
properly wear their seatbelt, even

when provided with an airbag
supplemental restraint system (SRS).

Your vehicle is equipped with a driver and
passenger airbag supplemental restraint
system. The supplemental restraint system
will activate in certain frontal and offset
frontal collisions when the vehicle sustains
sufficient frontal deceleration.

Careless or high speed driving while
plowing snow that results in sufficient
vehicle decelerations can deploy the
airbags. Such driving also increases the risk
of accidents.

Never remove or defeat the tripping
mechanisms designed into the snow
removal equipment by its manufacturer.
Doing so may cause damage to the vehicle
and the snow removal equipment as well
as possible airbag deployment.

Engine temperature while plowing

When driving with a plow, your engine may
run at a higher temperature than normal
because the attached snowplow blade will
restrict airflow to the radiator.
