steering FORD SUPER DUTY 2021 Manual PDF

In addition to providing an excellent
on-road driving experience, your vehicle
excels at all types of off-road driving. Your
vehicle has been designed and equipped
to allow you to explore those places where
the road doesn
’t take you, whether it’ s a
forest trail or the open desert. Before going
off-roading, consult with your local
governmental agencies to determine
designated off-road trails and recreation
areas. Also, be sure to understand any
off-road vehicle registration requirements
for the area in which you plan on driving.
Tread Lightly® is an educational program
designed to increase public awareness of
land-use regulations and responsibilities
in our nation ’s wilderness areas. Ford joins
the U.S. Forest Service and Bureau of Land
Management in encouraging you to help
preserve our national forest and other
public and private lands by treading lightly.
Before taking your vehicle off-roading, a
basic vehicle inspection should be
conducted to make sure that the vehicle
is in peak operating condition.
It is always recommended that at least
two vehicles are used while off-roading.
The buddy system helps make sure that
help is close at hand should a vehicle
become stuck or damaged. It is also wise
to take supplies such as a first aid kit,
drinking water, tow strap, cell or satellite
phone with you any time an off-road
excursion is planned.
Remove the front license plate before
off-roading to achieve optimal
performance. Basic Off-road Driving Techniques
•
Grip the steering wheel with thumbs
on the outside of the rim. This reduces
the risk of injury due to abrupt steering
wheel motions that occur when
negotiating rough terrain. Do not grip
the steering wheel with thumbs inside
the rim.
• Throttle, brake and steering inputs
should be made in a smooth and
controlled manner. Sudden inputs to
the controls can cause loss of traction
or upset the vehicle, especially while
on sloped terrain or while crossing
obstacles such as rocks or logs.
• Look ahead on your route noting
upcoming obstacles, changes to
surface texture, color changes and any
other factors which may indicate a
change in available traction. Adjusting
the vehicle speed and route
accordingly. During pre-run, mark
obstacles with GPS markers to make
sure appropriate speeds are used to
avoid potential vehicle damage.
• When driving off-road, if the front or
rear suspension is bottoming-out
and/or excessive contact with the
skid-plates is encountered, reduce
vehicle speed to avoid potential
damage to the vehicle.
• When running with other vehicles, it is
recommended that some form of radio
communication is used so the lead
vehicle can notify others of obstacles
that could cause damage.
• Always keep available ground
clearance in mind and pick a route that
minimizes the risk of catching the
underside of the vehicle on an obstacle.

•
When negotiating low speed obstacles,
applying light brake pressure in
conjunction with the throttle will help
prevent the vehicle from lurching and
will allow you to negotiate the obstacle
in a more controlled manner. Using 4L
also assists with this.
• Use and equip supplemental safety
equipment.
• Please consult your local off-road
group for other helpful tips.
• Off-roading requires a high degree of
concentration. Even if your local law
does not prohibit alcohol use while
driving off-road, Ford strongly
recommends against drinking alcohol
if you plan to off-road.
Crossing Obstacles
• Review the path ahead before
attempting to cross any obstacles. It is
best if the obstacles are reviewed from
outside the vehicle so that there is a
good understanding of the terrains
condition both in front of and behind
the obstacles.
• Approach obstacles slowly and slowly
creep the vehicle over.
• If a large obstacle such as a rock
cannot be avoided, choose a path that
places the rock directly under the tire
rather than the undercarriage of the
vehicle. This helps prevent damage to
the vehicle.
• Ditches and washouts should be
crossed at a 45 degree angle, allowing
each wheel to independently cross the
obstacle. Hill Climbing WARNING: Extreme care should
be used when steering the vehicle in
reverse down a slope so as not to cause
the vehicle to swerve out of control.
• Always attempt to climb a steep hill
along the fall line of the slope and not
diagonally.
• If the vehicle is unable to make it up
the hill, DO NOT attempt to turn back
down the slope. Place the vehicle in
low range and slowly back down in
reverse.
• When descending a steep slope, select
low gear and engage trail control. Use
the throttle and brake pedals to control
your descent speed as described earlier
in this section using trail control. Note
that trail control is functional in reverse
and should be used in this situation.
After Off-Road Driving
It is important to complete a full vehicle
inspection after off-road driving. Some
items to check include:
• Make sure that tires are inflated to
proper tire pressure as indicated on the
tire placard.
• Check the wheels and undercarriage
for built up mud or debris which can
cause vehicle vibration.
• Make sure that the grille and radiator
are clear of any obstructions that may
affect cooling.
• Make sure that the brakes are in proper
working order and free of any mud,
stones and debris, which can become
trapped around the brake rotor,
backing plate and caliper.
• Check that the air filter is clean and dry.
• Inspect for torn or punctured boots on
ball joints, half shafts, steering gears.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Second-Printing Driving Hints

•
Inspect exhaust system for damage or
looseness.
• Inspect undercarriage fasteners. If any
are loose or damaged, tighten or
replace ensuring that the proper torque
specification is used.
• Inspect the tires for any cuts in the
tread or sidewall area. Also inspect the
sidewall for any bulge indicating
damage to the tire.
• Inspect the wheels for dents, cracks,
or other damage.
• Refit the front license plate if removed
previously.
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
Engine Oil Capacity and Specification
(page
449).
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:
Engine damage can occur if water
enters the air filter.
For Vehicles without Tremor Off-
Road Package
Note: Driving through standing water can
cause vehicle damage.
Note: Drive through water in an emergency
only and not as part of normal driving.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs. 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.

For Vehicles with Tremor Off-Road
Package
Your vehicle equipped with Tremor
Off-Road package is capable of traveling
through water at a maximum depth of
33 in (837 mm). When driving through
standing water do not exceed crawl speed
of
4 mph (7 km/h).
• Always determine the depth before
attempting a water crossing.
• Proceed slowly and avoid splashing
water any more than is necessary. As
the water depth increases, vehicle
speed must be reduced to avoid
potential vehicle damage.
• Be aware that obstacles and debris
may be beneath the water ’s surface.
• Keep the doors fully closed during the
water crossing.
• Upon completion of the water crossing,
slowly drive a short distance and check
the brakes for full effectiveness.
SNOW PLOWING
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.
