Shifting between system modes
Note:
Do not perform these operations if
the rear wheels are slipping.
Note: Some noise may be heard as the 4x4
system shifts or engages. This is normal. In
order to reduce engagement noise, it is
recommended that all shifts be performed
at speeds below 3 mph (5 km/h).
Note: The vehicle should not be driven in
4X4 High with the hub locks disengaged as
this condition may damage driveline system
components.
Engage the locking hubs by rotating the
hub lock control from FREE to LOCK, then
move the transfer case lever from 2H
(2WD) to 4H (4x4 High) at a stop or a
vehicle speed below 3 mph (5 km/h).
Move the transfer case lever from 4H (4x4
High) to 2H (2WD) at a stop or a vehicle
speed below 3 mph (5 km/h), then
disengage the locking hubs (optional) by
rotating the hub lock control from LOCK
to FREE.
For proper operation, make sure that both
indicator arrows on the hub are aligned,
and that both hubs are set to either FREE
or LOCK.
Shifting to/from 4L (4x4 Low)
1. Bring the vehicle to a stop or a speed below 3 mph (5 km/h).
2. Place the transmission in N (Neutral).
3. Move the transfer case shift lever through N (Neutral) directly to the
desired position.
4. If the transfer case does not, or only partially moves to the desired position,
perform a shift with the transmission
in N (Neutral) and the vehicle rolling at
a speed below 3 mph (5 km/h). 5.
If shifting to 2H (2WD) with the vehicle
at a complete stop, disengage the
locking hubs (optional) by rotating the
hub lock control from LOCK to FREE.
Using the N (Neutral) position WARNING
Do not leave the vehicle unattended
with the transfer case in the N
(Neutral) position. Always set the
parking brake fully and turn off the ignition
when leaving the vehicle. The transfer case neutral position overrides
the transmission and puts the vehicle in
neutral regardless of transmission gearshift
lever position. The vehicle can move
forward or backwards.
This position should only be used when
towing the vehicle.

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
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: •
On 2WD vehicles and 4WD vehicles in
2H (4X2) or 4H (4X4 High), the ELD
will not engage if the vehicle speed is
above 20 mph (32 km/h).
• On 2WD vehicles and 4WD vehicles in
2H (4X2) or 4H (4X4 High), the ELD
will automatically disengage at speeds
above 25 mph (40 km/h) and will
automatically reengage at speeds
below 20 mph (32 km/h).
• On 4WD vehicles in 4L (4X4 Low), the
ELD can be engaged at any speed and
will not automatically disengage.
Activating the Electronic Locking
Differential (If Equipped)
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 vehicles equipped with an
electronic shift 4WD system Pull the 4WD control knob toward you.

GENERAL INFORMATION
Note:
Occasional brake noise is normal. If
a metal-to-metal, continuous grinding or
continuous squeal sound is present, the
brake linings may be worn-out. Have the
system checked by an authorized dealer. If
your vehicle has continuous vibration or
shudder in the steering wheel while braking,
have it checked by an authorized dealer.
Note: Brake dust may accumulate on the
wheels, even under normal driving
conditions. Some dust is inevitable as the
brakes wear and does not contribute to
brake noise. See Cleaning the Alloy
Wheels (page 251). See
Warning Lamps and
Indicators (page 77).
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.
Brake Over Accelerator
In the event the accelerator pedal
becomes stuck or entrapped, apply steady
and firm pressure to the brake pedal to
slow the vehicle and reduce engine power.
If you experience this condition, apply the
brakes and bring your vehicle to a safe
stop. Move the transmission selector lever
to position
P, switch the engine off and
apply the parking brake. Inspect the
accelerator pedal for any interference. If
none are found and the condition persists,
have your vehicle towed to the nearest
authorized dealer. Brake Assist
Brake assist detects when you brake
rapidly by measuring the rate at which you
press the brake pedal. It provides
maximum braking efficiency as long as you
press the pedal, and can reduce stopping
distances in critical situations.
Anti-lock Brake System
This system helps you maintain steering
control during emergency stops by keeping
the brakes from locking.
This lamp momentarily
illuminates when you turn the
ignition on. If the light does not
illuminate during start up, remains on or
flashes, the system may be disabled. Have
the system checked by an authorized
dealer. If the system is disabled, normal
braking is still effective. If the
brake warning lamp illuminates
when you release the parking brake, have
the system checked by an authorized
dealer.
HINTS ON DRIVING WITH
ANTI-LOCK BRAKES
Note: When the system is operating, the
brake pedal will pulse and may travel
further. Maintain pressure on the brake
pedal. You may also hear a noise from the
system. This is normal.
The anti-lock braking system will not
eliminate the risks when:
• you drive too closely to the vehicle in
front of you
• your vehicle is hydroplaning
• you take corners too fast
• the road surface is poor.

The system detects certain objects while
the transmission is in R (Reverse):
• and moving toward a stationary object
at a speed of 3 mph (5 km/h) or less
• but not moving, and a moving object is
approaching the rear of the vehicle at
a speed of 3 mph (5 km/h) or less
The system can be switched off through
the information display. If a fault is present
in the system, a warning message appears
in the information display and does not
allow the driver to switch the faulted
system on.
REAR VIEW CAMERA (IF EQUIPPED) WARNINGS
The rear view camera system is a
reverse aid supplement device that
still requires the driver to use it in
conjunction with the interior and exterior
mirrors for maximum coverage. Objects that are close to either
corner of the bumper or under the
bumper, might not be seen on the
screen due to the limited coverage of the
camera system. WARNINGS
Back up as slow as possible since
higher speeds might limit your
reaction time to stop the vehicle.
Use caution when using the rear
video camera and the liftgate is ajar.
If the liftgate is ajar, the camera will
be out of position and the video image may
be incorrect. All guidelines (if enabled)
have been removed when the liftgate is
ajar. Use caution when turning camera
features on or off while in Reverse
(R). Make sure the vehicle is not
moving. The rear view camera system provides a
video image of the area behind your
vehicle.
During operation, lines appear in the
display that represent your vehicle
’s path
and proximity to objects behind your
vehicle. The camera is located on the tailgate.
Using the Rear View Camera
System
The rear view camera system displays
what is behind your vehicle when you place
the transmission in Reverse (R).
171
Super Duty (TFA) Parking AidsE130178
A E163192
The system uses two types of guides to
help you see what is behind your vehicle:
•
Fixed guidelines: Show the actual path
your vehicle is moving in while reversing
in a straight line. This can be helpful
when backing into a parking space or
aligning your vehicle with another
object behind you.
• Centerline: Helps align the center of
your vehicle with an object (for
example, a trailer).
Note: If the image comes on while the
transmission is not in Reverse (R), have the
system inspected by your authorized dealer.
Note: When towing, the camera only sees
what you are towing behind your vehicle.
This might not provide adequate coverage
as it usually provides in normal operation
and you might not see some objects. In
some vehicles, the guidelines may disappear
once you engage the trailer tow connector.
The camera may not operate correctly
under the following conditions:
• Nighttime or dark areas if the reverse
lamps are not operating.
• Mud, water or debris obstructs the
camera's view. Clean the lens with a
soft, lint-free cloth and non-abrasive
cleaner.
• The camera is misaligned due to
damage to the rear of your vehicle.
To access any of the rear view camera
system settings, make the following
selections in the touch screen when the
transmission is not in Reverse (R):
• Menu > Vehicle > Camera Settings
After changing a system setting, the touch
screen shows a preview of the selected
features.
Guidelines and the Centerline
Note: Fixed guidelines are only available
when the transmission is in R (Reverse). Note:
The centerline is only available if
fixed guidelines are on. Rear bumper

the steering wheel position is straight.
Always use caution while reversing.
Objects in the red zone are closest to your
vehicle and objects in the green zone are
farther away. Objects are getting closer to
your vehicle as they move from the green
zone to the yellow or red zones. Use the
side view mirrors and rear view mirror to
get better coverage on both sides and rear
of the vehicle.
Enhanced Park Aids
Note: Enhanced park aids is only available
when the transmission is in Reverse (R).
Note: The reverse sensing system is not
effective at speeds above 3 mph (5 km/h)
