PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It’ s always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator ’s ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN.
The system automatically turns on each
time you switch the ignition on. If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
•
The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
• The Adaptive Steering system (if
equipped) automatically changes the
steering function to a fixed steering
ratio. See
Steering (page 260).
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.
• The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the system applies
higher brake force.
The stability control system has several
features built into it to help you maintain
control of your vehicle:
Electronic Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.

Roll Stability Control
The system enhances your vehicle
’s ability
to prevent rollovers by detecting your
vehicle ’s roll motion and the rate at which
it changes by applying the brakes to one
or more wheels individually.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin. See
Using Traction Control (page 227). Vehicle without stability control

PRINCIPLE OF OPERATION
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING: The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING:
Traffic control
systems, inclement weather, air brakes,
external motors and fans may affect the
correct operation of the sensing
system.This may cause reduced
performance or false alerts. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground.
Note: Certain add-on devices installed
around the bumper or fascia may create
false beeps. For example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that may block the normal detection zone
of the system.
Note: Keep the sensors, located on the
bumper or fascia, free from snow, ice and
large accumulations of dirt. If the sensors
are covered, the system ’s accuracy can be
affected. Do not clean the sensors with
sharp objects.
Note: If your vehicle sustains damage to
the bumper or fascia, leaving it misaligned
or bent, the sensing zone may be altered
causing inaccurate measurement of
obstacles or false alarms. See your
authorized technician. Note:
When a trailer is connected to your
vehicle, the rear parking aid may detect the
trailer and therefore provide warnings.
Disable the rear parking aid when a trailer
is connected to prevent these warnings.
Note: The sensing system cannot be turned
off when a MyKey is present. See Principle
of Operation
(page 65).
The sensing system warns the driver of
obstacles within a certain range of your
vehicle. The system turns on automatically
whenever you switch the ignition on.
When receiving a detection warning, the
radio volume reduces to a predetermined
level. After the warning goes away, the
radio volume returns to the previous level.
The sensing system can be switched off
through the information display menu or
from the pop-up message that appears
once you shift the transmission into reverse
(R). See General Information (page 112).
If a fault is present in the system, a warning
message appears in the information
display and you cannot switch the system
on through the pop-up message. See
Information Messages
(page 128).
REAR PARKING AID
(IF EQUIPPED)
The rear sensors are only active when the
transmission is in reverse (R). As your
vehicle moves closer to the obstacle, the
rate of the audible warning increases.
When the obstacle is less than
11.81 in
(30 cm) away, the warning sounds
continuously. If the system detects a
stationary or receding object farther than
11.81 in (30 cm)
from the corners of the
bumper, the tone sounds for only two
seconds. Once the system detects an
object approaching, the warning sounds
again.

Automatic Cancellation
The system is not functional at vehicle
speeds below 12 mph (20 km/h). The
information display indicates low engine
speed, an audible alarm sounds and the
automatic braking releases if the vehicle
drops below this speed.
Automatic cancellation can also occur
when:
•
The tires lose traction.
• You apply the parking brake.
Note: If the engine speed drops too low, an
audible warning sounds and a message
appears in the information display.
Automatic braking releases.
Hilly Condition and Trailer Tow
Usage
You should select a lower gear when the
system is active in situations such as
prolonged downhill driving on steep
grades, for example in mountainous areas.
The system needs additional engine
braking in these situations to reduce the
load on the vehicle ’s regular brake system
to prevent it from overheating.
Note: An audible alarm sounds and the
system shuts down if it applies brakes for
an extended period of time. This allows the
brakes to cool. The system functions
normally again after the brakes cool.
Note: When towing with adaptive cruise
control, switch on Tow/Haul Mode and
Diesel Engine Brake.
Note: Tow/Haul mode increases the time
gaps and allows more distance for braking.
Switching Adaptive Cruise Control
Off Press and release the button
when the system is in standby
mode, or switch the ignition off. Note:
You erase the set speed and gap
setting when you switch the system off.
Detection Issues WARNING: On rare occasions,
detection issues can occur due to the
road infrastructures, for example bridges,
tunnels and safety barriers. In these
cases, the system may brake late or
unexpectedly. At all times, you are
responsible for controlling your vehicle,
supervising the system and intervening,
if required. WARNING:
If the system
malfunctions, have your vehicle checked
as soon as possible.
The radar sensor has a limited field of view.
It may not detect vehicles at all or detect
a vehicle later than expected in some
situations. The lead vehicle graphic does
not illuminate if the system does not
detect a vehicle in front of you.

System Warnings
Note:
The system will not issue warnings
below approximately 40 mph (64 km/h).
The warning system is in two stages. At
first the system issues a temporary warning
that you need to take a rest. This message
will only appear for a short time. If the
system detects further reduction in driving
alertness, another warning may be issued
which will remain in the information display
for a longer time. Press OK on the steering
wheel control to clear the warning. When
active the system will run automatically in
the background and only issue a warning
if required.
Resetting the System
You can reset the system by either:
• Switching the ignition off and on.
• Stopping the vehicle and then opening
and closing the driver ’s door.
LANE KEEPING SYSTEM
(IF
EQUIPPED) WARNING:
You are responsible
for controlling your vehicle at all times.
The system is designed to be an aid and
does not relieve you of your responsibility
to drive with due care and attention.
Failure to follow this instruction could
result in the loss of control of your
vehicle, personal injury or death. WARNING:
Always drive with due
care and attention when using and
operating the controls and features on
your vehicle. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all
limit sensor performance. WARNING:
The system will not
operate if the sensor cannot track the
road lane markings. WARNING:
The sensor may
incorrectly track lane markings as other
structures or objects. This can result in
a false or missed warning. WARNING:
Large contrasts in
outside lighting can limit sensor
performance. WARNING:
The system may not
operate properly if the sensor is blocked.
Keep the windshield free from
obstruction. WARNING:
If damage occurs in
the immediate area surrounding the
sensor, have your vehicle checked as
soon as possible. WARNING:
The system may not
correctly operate if your vehicle is fitted
with a suspension kit not approved by
us.
Note: The system works as long as the
camera can detect one lane marking at a
speed above
40 mph (64 km/h).
Note: The system may not function with a
blocked camera, or if the windshield is
damaged or dirty.
250
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201804, Fourth-Printing Driving Aids

The system uses radar sensors that are
located inside the tail lamp on each side
of your vehicle. Any dirt, mud and snow in
front of the sensors or driving in heavy rain
can cause system degradation. Also, other
types of obstructions in front of the sensor
can cause system degradation. This is
referred to as a
‘blocked ’ condition.
Note: Do not apply bumper stickers and/or
repair compound to these areas, this can
cause degraded system performance.
If the system detects a degraded
performance condition, a message warning
appears in the display screen. The alert
indicators remain ON and the system no
longer provides any warnings. You can
clear the warning but the alert indicators
remain illuminated.
A "blocked" condition can be cleared in
two ways:
• After the blockage in front of the
sensors is removed or the
rainfall/snowfall rate decreases or
stops, drive for a few minutes in traffic
to allow the sensors to detect passing
vehicles.
• By cycling the ignition from ON to OFF
and then back ON.
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Blind Spot
Information System off. If your vehicle has
a tow bar but no factory equipped trailer
tow module, it is recommended to turn the
Blind Spot Information System off
manually. Operating the Blind Spot
Information System without the Blind Spot
Trailer Tow package and a trailer attached
will cause poor system performance. Blind Spot Information System
with Trailer Tow (If Equipped)
The Blind Spot Information System with
Trailer Tow is designed to aid you in
detecting vehicles that may have entered
the detection area zone (A). The detection
area is on both sides of your vehicle and
trailer, extending rearward from the
exterior mirrors to the end of your trailer.
When a trailer is attached and the
customer has set up a Blind Spot Trailer,
the Blind Spot Information System with
Trailer Tow becomes active when driving
forward above
6 mph (10 km/h). See
Trailer Reversing Aids (page 275).
The Blind Spot Information System with
Trailer Tow can be turned off in the
instrument cluster. If the Blind Spot
Information System is turned off, then the
Blind Spot Information System with Trailer
Tow automatically turns off.

System Operation
If you select a trailer in the display screen
prior to connecting the trailer, the system
will load that configuration and the
information cluster displays a message
when the trailer is connected. A second
message appears stating Cross Traffic
Alert has been turned off; the Blind Spot
Information System with Trailer Tow still
functions normally when driving forward.
If no trailer has been set up and a trailer is
connected, the instrument cluster provides
a message indicating a trailer is connected
followed by a message asking to select a
trailer from the existing list of trailers or to
add a trailer. In order for the Blind Spot
Information System with Trailer Tow to
function, an existing trailer must be
selected or a new trailer must be added. If
the request is ignored or if you exit the
screen, a message appears prompting you
that the system has been turned off due
to a trailer connect. This message may not
appear until your vehicle speed reaches
22 mph (35 km/h).
The Blind Spot Information System with
Trailer Tow activates when driving forward
for that particular trailer set up. If the
ignition is cycled, the Blind Spot
Information System with Trailer Tow
continues to function using the last trailer
selected.
Trailer Considerations
The Blind Spot Information System with
Trailer Tow is designed to work with any
trailer whose front width is
8.5 ft (2.6 m)
or less and total length from the trailer
hitch ball to the rear of the trailer is
33 ft
(10.1 m) or less. Different trailers may
cause a slight change in performance as
outlined below. Large box trailers may cause false alerts
to trigger when driving next to buildings or
near parking cars. A false alert may also
occur while making a 90-degree turn.
Trailers that are
8.5 ft (2.6 m) wide at the
front and have a total length greater than
20 ft (6 m)
may have delayed alerts from
passing vehicles when the vehicle is
passing at high speed.
A box trailer whose front width is
8.5 ft
(2.6 m) may cause early alerts when you
are over taking a vehicle.
When towing a clam shell or V-Nose box
trailer with a front width of
8.5 ft (2.6 m),
delayed alerts on merging vehicles that are
traveling the same speed as your vehicle
may occur.
System Errors
If the system senses a problem with the
left or right sensor, the telltale illuminates
and a message appears in the display
screen. See
Information Messages
(page 128).
Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the display
screen. See
General Information (page
112). When the Blind Spot Information
System switches off, you do not receive
alerts and the display screen shows a
system off message. The telltale in the
cluster also illuminates. When you switch
the Blind Spot Information System on or
off, the alert indicators flash twice.
Note: The Blind Spot Information System
remembers the last selected on or off
setting.
You can also have the Blind Spot
Information System switched off
permanently at an authorized dealer. Once
switched off permanently, the system can
only be switched back on at an authorized
dealer.

System Limitations
Cross Traffic Alert has its limitations;
situations such as severe weather
conditions or debris build-up on the sensor
area may limit vehicle detection and cause
false alerts.
The following are other situations that may
limit the Cross Traffic Alert performance:
•
Adjacently parked vehicles or objects
obstructing the sensors.
• Approaching vehicles passing at
speeds greater than 37 mph
(60 km/h).
• Driving in reverse faster than
7 mph
(12 km/h).
• Backing out of an angled parking spot.
False Alerts
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Cross Traffic Alert
off. If your vehicle has a tow bar but no
factory equipped trailer tow module, it is
recommended to turn the Cross Traffic Alert
off manually. Operating Cross Traffic Alert
with a trailer attached will cause poor Cross
Traffic Alert performance.
Note: The system may illuminate the amber
alert indicator and sound the audible alert
during heavy rain even though no vehicle is
approaching from left or right.
There may be certain instances when there
is a false alert by the Cross Traffic Alert
system that illuminates the alert indicator
with no vehicle in the coverage zone. Some
amount of false alerts are normal; they are
temporary and self-correct. System Errors
If Cross Traffic Alert senses a problem with
the left or right sensor a message appears
in the display screen. See
Information
Messages (page 128).
Switching the System Off and On
Note: The Cross Traffic Alert switches on
whenever the ignition is switched on and
ready to provide appropriate alerts when
the transmission is in reverse (R). Cross
Traffic Alert will not remember the last
selected on or off setting.
You can temporarily switch Cross Traffic
Alert off in the information display. See
General Information
(page 112). When
you switch Cross Traffic Alert off, you do
not receive alerts and the display screen
shows a system off message.
You can also have Cross Traffic Alert
switched off permanently at an authorized
dealer. Once switched off permanently,
the system can only be switched back on
at an authorized dealer.
STEERING
Hydraulic Power Steering
To help prevent damage to the power
steering system:
• Do not hold the steering wheel at its
furthest turning points for more than
three to five seconds when the engine
is running.
• Avoid continuously steering back and
forth with elevated engine RPM as this
may overheat the system. If trying to
free a stuck vehicle, pause between
attempts to allow the power steering
system to cool or seek assistance.
Typical steering and driving maneuvers
allow the system to cool.
260
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 201804, Fourth-Printing Driving Aids

•
Do not operate the vehicle if the power
steering pump fluid level is below the
MIN mark on the reservoir.
• Some noise is normal during operation.
If excessive, check for low power
steering pump fluid level before
seeking service by your dealer.
• Heavy or uneven efforts may be caused
by low power steering fluid. Check for
low power steering pump fluid level
before seeking service by your dealer.
• Do not fill the power steering pump
reservoir above the MAX mark on the
reservoir, as this may result in leaks
from the reservoir.
If the power steering system breaks down
or if you switch the engine off, you can
steer the vehicle manually, but it takes
more effort.
If you have any steering components
serviced or replaced, install new fasteners.
Many fasteners have coatings with thread
adhesive, or have prevailing torque
features you cannot reuse. Do not reuse a
bolt or nut. Torque fasteners to
specifications.
Steering Tips
If the steering wanders or pulls, check for:
• An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
Note: A high crown in the road or high
crosswinds may also make the steering
seem to wander or pull. Electronic Variable Overlay Power
Steering (If Equipped) WARNING:
The electric power
steering system has diagnostic checks
that continuously monitor the system. If
a fault is detected, a message displays
in the information display. Stop your
vehicle as soon as it is safe to do so.
Switch the ignition off. After at least 10
seconds, switch the ignition on and
watch the information display for a
steering system warning message. If a
steering system warning message
returns, have the system checked as
soon as possible. WARNING:
If the system detects
an error, you may not feel a difference in
the steering, however a serious condition
may exist. Have your vehicle checked as
soon as possible. Failure to do so may
result in loss of steering control.
The electronic variable overlay power
steering system adds supplemental
steering assist to the hydraulic gear when
needed, dependent on vehicle conditions
such as vehicle speed, steering wheel
angle, and steering wheel torque. The
hydraulic steering system provides the
majority of steering assistance. The
electronic variable overlay torque enables
features such as pro trailer backup
assistance and lane departure warning.
If your vehicle loses electrical power while
you are driving, your vehicle loses electric
power steering assistance. The steering
system still operates, and you can steer
your vehicle with hydraulic assist. Steering
your vehicle with only hydraulic assist
requires more effort.
