You can set-up any trailer to work with the
Blind Spot Information System with Trailer
Tow through the instrument cluster menu.
See General Information (page 110).
While setting up a trailer, a sequence of
screens appear asking for trailer
information. The Blind Spot Information
System with Trailer Tow specific screens
are described below:
• Select type of trailer screen -
Conventional, fifth wheel or gooseneck.
The Blind Spot Information System with
Trailer Tow only supports conventional
trailers. If fifth wheel or gooseneck is
selected, the system automatically turns
off.
• Do you want to set up BLIS with trailer
screen?
If no, the Blind Spot Information System
turns off.
If yes, the menu goes to the next screen.
• Is the width less than
9 ft (2.7 m) and
length less than 33 ft (10.1 m)?
If no, the Blind Spot Information System
turns off.
If yes, the menu goes to the next screen.
• Trailer width measurement: The width of the trailer is measured at the
front of the trailer. It is not measured at the
widest point of the trailer. The maximum
width at the front of the trailer that the
Blind Spot Information System with Trailer
Tow can support is
8.5 ft (2.6 m).
Note: You do not need to enter an exact
trailer width measurement; just measure
that it is
8.5 ft (2.6 m) or less.
• Trailer length measurement:
The trailer length is the distance between
the trailer hitch ball and the rear of the
trailer. The maximum length that the Blind
Spot Information System with Trailer Tow
can support is
33 ft (10.1 m).
• Enter length of trailer:
The default setting is
18 ft (5.5 m).
Toggling up or down using the menu
buttons will increase/decrease the
measurement by
3 ft (1 m). Select the
length so that the value is equal to or
within
3 ft (1 m) of the actual measured
length. For example, if the actual measured
length is
25 ft (7.6 m), then toggle the
length in the menu to 27 ft (8.2 m). When
the length has been entered, the Blind Spot
Information System with Trailer Tow setup
is saved.
If you do not set up a Blind Spot Trailer, a
warning appears in the instrument cluster
when a trailer is connected stating that the
system has been turned off due to a trailer
connect.
Note: If the trailer is actually a bike rack or
cargo rack with electrical lighting, then the
length will be
3 ft (1 m). Cross Traffic Alert
will remain on for trailers 3 ft (1 m) or less.
Note: Proper measurement and
measurement entry is required for Blind
Spot Information System with Trailer Tow
to function as designed.

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 121).
Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the display
screen. See
General Information (page
110). 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.

Cross Traffic Alert Behavior When
Trailer is Attached
Note:
The system may not correctly operate
when towing a trailer. For vehicles with an
approved trailer tow module and tow bar,
the system turns off when you attach a
trailer. For vehicles with an aftermarket
trailer tow module or tow bar, we
recommend that you switch the system off
when you attach a trailer.
Cross traffic alert remains on when you
attach a trailer in vehicles that come with
blind spot information system with trailer
tow under the following conditions:
• You connect a trailer.
• The trailer is a bike rack or cargo rack
with a maximum length of 3 ft (1 m).
• You set the trailer length to
3 ft (1 m)
in the information display.
See
Blind Spot Information System
(page 254).
Switching the System On and Off
To switch the system on or off, adjust the
setting. Depending on your vehicle options,
the setting could be in the following: •
Information display. See
General
Information (page 110).
• Touchscreen. See Settings (page 543).
Note: The system turns on every time you
switch the ignition on. To permanently
switch the system off, contact an authorized
dealer.
Cross Traffic Alert Indicator When the system detects an
approaching vehicle, a tone
sounds, a warning lamp
illuminates in the relevant exterior mirror
and arrows appear in the information
display to show which side the
approaching vehicle is coming from.
Note: If arrows do not display, a message
appears in the information display.
If the system malfunctions, a warning lamp
illuminates in the instrument cluster and
a message appears in the information
display. Have your vehicle checked as soon
as possible.
Note: In exceptional conditions, the system
could alert you, even when there is nothing
in the detection zone, for example a vehicle
passing further away from your vehicle.

The electronic torque overlay 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 torque
overlay 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.
Extreme continuous steering may increase
the effort required for you to steer your
vehicle. This increased effort prevents
overheating and permanent damage to
the steering system. You do not lose the
ability to steer your vehicle manually.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.
Adaptive Learning (If Equipped)
The electronic power steering system
adaptive learning helps correct road
irregularities and improves overall handling
and steering feel. It communicates with
the brake system to help operate
advanced stability control and accident
avoidance systems. Whenever the battery
is disconnected or a new battery installed,
you must drive your vehicle a short
distance before the system relearns the
strategy and reactivates all systems. Adaptive Steering
(If Equipped)
Note: The adaptive steering system has
diagnostic checks that continuously monitor
the system. If the system detects a fault, a
message displays in the information display.
If a red warning message displays, stop your
vehicle as soon as it is safe to do so. The
message may clear if the fault is no longer
present. If an adaptive steering system
warning message appears each time you
start your vehicle, have the system checked
as soon as possible.
The adaptive steering system continually
changes the steering ratio with changes to
vehicle speed, optimizing the steering
response in all conditions. The system also
changes when you switch on the
transmission tow/haul feature. When you
select the tow/haul button, the adaptive
steering system reduces vehicle sensitivity
to steering inputs at higher vehicle speeds,
while maintaining the ease of parking and
maneuverability at low speeds.
Note: The adaptive steering system is
designed with a locking device. With the
lock engaged, the adaptive steering system
remains mechanically locked at a fixed
steering ratio. You may also notice a click
when you switch the vehicle on or after you
switch it off, as the lock disengages or
engages.
Note: If your vehicle loses electrical power
or detects a fault when you are driving, the
system automatically shuts down and you
retain normal steering function with a fixed
steering ratio. During this time it is possible
that the steering wheel may not be straight
when the vehicle is driving straight ahead.
In addition, the driver may notice that the
steering wheel angle required to steer the
vehicle may be different.
263
Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Driving Aids

Note:
During parking maneuvers, the
adaptive steering system balances the driver
work load for various steering wheel inputs
and vehicle loading conditions. Under
extreme operating conditions the system
locking device may engage. This strategy
prevents overheating and permanent
damage to the adaptive steering system.
Typical steering and driving maneuvers
allow the system to cool and return to
normal operation.

when the road surface is slippery. Failure
to follow this instruction could result in
the loss of control of your vehicle. Tow/Haul – For improved
transmission operation when
towing a trailer or a heavy load.
This mode moves upshifts to higher engine
speeds to reduce the frequency of
transmission shifting. This mode also
provides engine braking in all forward
gears, which slows your vehicle and assists
you in controlling your vehicle when
descending a grade. The amount of
downshift braking provided varies based
on the amount you press the brake pedal. Deep Snow/Sand – For snow or
soft, dry sand.
Eco – For efficient driving. This
mode helps deliver maximum
fuel efficiency and helps to
increase driving range. Slippery – For less than ideal
road conditions such as snow or
ice covered roads. Use this mode
for crossing terrain where loose, wet or
slippery material covers a firm surface.
Slippery mode lowers throttle response
and, if equipped with automatic
transmission, optimizes shifting for slippery
surfaces. Rock Crawl – For optimum
