After driving through mud, clean off residue
stuck to rotating driveshafts and tires.
Excess mud stuck on tires and rotating
driveshafts can cause an imbalance that
could damage drive components.
Water
If you must drive through high water, drive
slowly. Traction or brake capability may
be limited.
When driving through water, determine the
depth and avoid water higher than the
bottom of the hubs. If the ignition system
gets wet, your vehicle may stall.
Once through water, always try the brakes.
Wet brakes do not stop your vehicle as
effectively as dry brakes. Drying can be
improved by applying light pressure to the
brake pedal while moving slowly.
Note:
Driving through deep water may
damage the transmission. If the front or rear
axle is submerged in water, the axle
lubricant and power transfer unit lubricant
should be checked and changed if
necessary.
Driving on Hilly or Sloping Terrain
Although natural obstacles may make it
necessary to travel diagonally up or down
a hill or steep incline, you should always
try to drive straight up or straight down.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you will use. Do not
drive over the crest of a hill without seeing
what conditions are on the other side. Do
not drive in reverse over a hill without the
aid of an observer.
When climbing a steep slope or hill, start
in a lower gear rather than downshifting to
a lower gear from a higher gear once the
ascent has started. This reduces strain on
the engine and the possibility of stalling. If your vehicle stalls, do not try to turn
around because this could cause vehicle
roll over. It is better to reverse back to a
safe location.
Apply just enough power to the wheels to
climb the hill. Too much power will cause
the tires to slip, spin or lose traction,
resulting in loss of vehicle control.
Descend a hill in the same gear you would
use to climb up the hill to avoid excessive
brake application and brake overheating.
Do not descend in neutral. Disengage
overdrive or move the transmission
selector lever to a lower gear. When
descending a steep hill, avoid sudden hard
braking as you could lose control. The front
wheels have to be turning in order to steer
your vehicle.
If your vehicle has anti-lock brakes, apply
the brakes steadily. Do not pump the
brakes.

LIMITED SLIP DIFFERENTIAL
This axle provides added traction on
slippery surfaces, particularly when one
wheel is on a poor traction surface. Under
normal conditions, the limited-slip axle
functions like a standard rear axle. The axle
may exhibit a slight noise or vibration
during tight turns with low vehicle speed.
This is normal behavior and indicates the
axle is working.
ELECTRONIC LOCKING
DIFFERENTIAL (If Equipped)
Note: The electronic locking differential is
for off-road use only and is not for use on
dry pavement. Using the electronic locking
differential on dry pavement will result in
increased tire wear, noise and vibration.
The electronic locking differential is a
device housed in the rear axle that allows
both rear wheels to turn at the same
speed. The electronic locking differential
can provide additional traction should your
vehicle become stuck. You can activate
the differential electronically and shift it
on the fly within the differential operating
speed range. The differential is for use in
mud, rocks, sand, or any off-road condition
where you need maximum traction. It is
not for use on dry pavement.
The following conditions will affect the
electronic locking differential:
• The electronic locking differential will
not engage if your vehicle speed is
above
20 mph (32 km/h) in 4x2 or 4x4
High modes.
• The electronic locking differential will
not engage if your vehicle speed is
above or
56 mph (90 km/h) in 4X4
Low. •
The electronic locking differential may
not engage if you press your
accelerator pedal during an
engagement attempt. A message may
display in the instrument display
guiding you to release the accelerator
pedal.
• In 4x2 or 4x4 High modes, the
electronic locking differential will
automatically disengage at speeds
above
25 mph (41 km/h) and will
automatically reengage at speeds
below
20 mph (32 km/h).
• In 4L (4X4 low), the electronic locking
differential will automatically
disengage at speeds above
62 mph
(100 km/h) and will automatically
reengage at speeds below 56 mph
(90 km/h).
• The AdvanceTrac system has the
ability to take over control of the
electronic locking differential and
disable it during driving maneuvers
when necessary.
When you switch the system on, if you do
not meet the required conditions for
electronic locking differential activation,
the instrument cluster will display the
appropriate information guiding you
through the proper activation process.
Activating the Electronic Locking
Differential
Note: Do not use electronic locking
differential on dry, hard surfaced roads.
Doing so will produce excessive noise,
vibration and increase tire wear.
Note: If the electronic locking differential
has difficulty disengaging, release the
accelerator pedal and turn the steering
wheel in the opposite direction while rolling.

For 4WD vehicles
Pull the 4WD control knob toward you.
For 2WD vehicles
Turn the control to ON.
Once the indicator light
illuminates in the information
display, both rear wheel axle
shafts will be locked together providing
added traction.
If the indicator does not come on, or the
indicator turns off while driving, one of the
following has occurred: •
The vehicle speed is too high.
• The left and right rear wheel speed
difference is too high during an
engagement attempt.
• The system has malfunctioned and is
accompanied by a message in the
information display. See your
authorized Ford dealer for assistance.

Payload is the combined weight
of cargo and passengers that your
vehicle is carrying. The maximum
payload for your vehicle appears
on the Tire and Loading label. The
label is either on the B-pillar or the
edge of the driver door. Vehicles
exported outside the US and
Canada may not have a tire and
loading label. Look for
“The
combined weight of occupants
and cargo should never exceed
XXX kg OR XXX lb ” for maximum
payload. The payload listed on the
Tire and Loading Information label
is the maximum payload for your
vehicle as built by the assembly
plant. If you install any additional
equipment on your vehicle, you
must determine the new payload.
Subtract the weight of the
equipment from the payload listed
on the Tire and Loading label.
When towing, trailer tongue
weight or king pin weight is also
part of payload. WARNING
The appropriate loading
capacity of your vehicle can
be limited either by volume
capacity (how much space is
available) or by payload capacity
(how much weight the vehicle
should carry). Once you have
reached the maximum payload of
your vehicle, do not add more
cargo, even if there is space
available. Overloading or
improperly loading your vehicle
can contribute to loss of vehicle
control and vehicle rollover. GAWR (Gross Axle Weight
Rating)
GAWR is the maximum allowable
weight that a single axle (front or
rear) can carry. These numbers
are on the Safety Compliance
Certification label. The label is
located on the door hinge pillar,
door-latch post, or the door edge
that meets the door-latch post,
next to the driver seating position.
The total load on each axle must
never exceed its Gross Axle
Weight Rating.
GVWR (Gross Vehicle Weight
Rating)
GVWR is the maximum allowable
weight of the fully loaded vehicle.
This includes all options,
equipment, passengers and cargo.
It appears on the Safety
Compliance Certification label.
The label is located on the door
hinge pillar, door-latch post, or the
door edge that meets the
door-latch post, next to the driver
seating position.
The gross vehicle weight must
never exceed the Gross Vehicle
Weight Rating.

enough load capacity in your
vehicle to transport four friends
and your golf bags. In metric units,
the calculation would be: 635
kilograms - (5 x 99 kilograms) -
(5 x 13.5 kilograms) = 635 - 495 -
67.5 = 72.5 kilograms.
Suppose your vehicle has a
1400-pound (635-kilogram) cargo
and luggage capacity. You and
one of your friends decide to pick
up cement from the local home
improvement store to finish that
patio you have been planning for
the past two years. Measuring the
inside of the vehicle with the rear
seat folded down, you have room
for twelve 100-pound
(45-kilogram) bags of cement. Do
you have enough load capacity to
transport the cement to your
home? If you and your friend each
weigh 220 pounds (99 kilograms),
the calculation would be: 1400 -
(2 x 220) - (12 x 100) = 1400 - 440
- 1200 = - 240 pounds. No, you do
not have enough cargo capacity
to carry that much weight. In
metric units, the calculation would
be: 635 kilograms - (2 x 99
kilograms) - (12 x 45 kilograms) =
635 - 198 - 540 = -103 kilograms.
You will need to reduce the load
weight by at least 240 pounds
(104 kilograms). If you remove
three 100-pound (45-kilogram)
cement bags, then the load
calculation would be:1400 - (2 x
220) - (9 x 100) = 1400 - 440 -
900 = 60 pounds. Now you have
the load capacity to transport the
cement and your friend home. In
metric units, the calculation would
be: 635 kilograms - (2 x 99
kilograms) - (9 x 45 kilograms) =
635 - 198 - 405 = 32 kilograms.
The above calculations also
assume that the loads are
positioned in your vehicle in a
manner that does not overload
the front or the rear gross axle
weight rating specified for your
vehicle on the Safety Compliance
Certification label.
Special Loading Instructions
for Owners of Pick-up Trucks
and Utility-type Vehicles
WARNING
Loaded vehicles may handle
differently than unloaded
vehicles. Take extra precautions,
such as slower speeds and
increased stopping distance, when
driving a heavily loaded vehicle. BED RAMPS (If Equipped)
WARNINGS
When sliding the ramp up or down,
take care not to get your fingers or
hands caught in the mechanism.
Failure to follow this instruction could
result in personal injury. Make sure that you correctly install
the ramp to the tailgate plate. Failure
to follow this instruction could result
in personal injury.

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
certification label. Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of your vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Do not exceed the lowest
rating capacity for your
vehicle or trailer hitch. Overloading
your vehicle or trailer hitch can
impair your vehicle stability and
handling. Failure to follow this
instruction could result in the loss
of control of your vehicle, personal
injury or death. Do not cut, drill, weld or
modify the trailer hitch.
Modifying the trailer hitch could
reduce the hitch rating. Note:
To prevent your trailer from
accumulating distance, and the
trailer information status appearing
when you restart your vehicle after
disconnecting your trailer, you must
deactivate your trailer. Using the
information display, go to the
Towing menu and then the Select
Trailer option. Select the No active
trailer option. See Information
Displays (page 113).
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 317).
Your vehicle may have ability to
modify trailer towing features.
See
General Information (page
113).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading a vehicle or trailer.
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.
272
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201709, Second Printing Towing

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.
• Select a ball mount with the
correct rise or drop. When both
the loaded vehicle and trailer
are connected, the trailer frame
should be level, or slightly
angled down toward your
vehicle, when viewed from the
side. When driving with a trailer or
payload, a slight takeoff vibration
or shudder may be present due to
the increased payload weight.
Additional information regarding
proper trailer loading and setting
your vehicle up for towing is
located in another chapter of this
manual. See Load Limit (page
264).
