Ford Super Duty (2017 year). Manual — part 72

•

Fuel economy may decrease with lower
temperatures during the first 8–10
miles (12–16 kilometers) 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

Always use floor mats that are
designed to fit the foot well of your
vehicle. Only use floor mats that

leave the pedal area unobstructed. Only
use floor mats that are firmly secured to
retention posts so that they cannot slip out
of position and interfere with the pedals
or impair safe operation of your vehicle in
other ways.

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

injury.

Always make sure that the floor
mats are properly attached to the
retention posts in the carpet that are

supplied with your vehicle. Floor mats must
be properly secured to both retention posts
to make sure mats do not shift out of
position.

Never place floor mats or any other
covering in the vehicle foot well that
cannot be properly secured to

prevent them from moving and interfering
with the pedals or the ability to control the
vehicle.

291

WARNINGS

Never place floor mats or any other
covering on top of already installed
floor mats. Floor mats should always

rest on top of vehicle carpeting surface and
not another floor mat or other covering.
Additional floor mats or any other covering
will reduce the pedal clearance and
potentially interfere with pedal operation.

Check attachment of floor mats on
a regular basis. Always properly
reinstall and secure floor mats that

have been removed for cleaning or
replacement.

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

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

Failure to properly follow floor mat
installation or attachment
instructions can potentially cause

interference with pedal operation causing
a loss of vehicle control.

E142666

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

To remove the floor mat, reverse the
installation procedure.

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.

292

•

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.

293

•

If you are driving more than 15 mi
(24 km) at temperatures above
freezing, angle the plow blade either
full left or full right to provide
maximum airflow to the radiator.

•

If you are driving less than 15 mi
(24 km) at speeds up to 45 mph
(72 km/h) in cold weather, you will not
need to worry about blade position to
provide maximum airflow.

Transmission operation while
plowing

WARNING

Do not spin the wheels at over
34 mph (55 km/h). The tires may fail
and injure a passenger or bystander.

•

Shift transfer case to 4L (4WD Low)
when plowing in small areas at speeds
below 5 mph (8 km/h).

•

Shift transfer case to 4H (4WD High)
when plowing larger areas or light snow
at higher speeds. Do not exceed 15 mph
(24 km/h).

•

Do not shift the transmission from a
forward gear to R (Reverse) until the
engine is at idle and the wheels have
stopped.
