Why does the vehicle not come back into the middle of the lane always, as expected, in
the Aid or Aid + Alert mode?
Heavy uneven loading of the vehicle or improper tire inflation pressure
If the tires have been exchanged (including snow tires), or the suspension has been
modified
Vehicle accessories such as snow plows or trailers
BLIND SPOT INFORMATION
SYSTEM WARNING
To help avoid injuries, NEVER use the
Blind Spot Information System as a
replacement for using the interior
and exterior mirrors or looking over your
shoulder before changing lanes. The Blind
Spot Information System is not a
replacement for careful driving. The Blind Spot Information System is
designed to aid you in detecting vehicles
that may have entered the blind spot zone
(A). The detection area is on both sides of
your vehicle, extending rearward from the
exterior mirrors to approximately 13 ft
(4 m) beyond the bumper. The system is
designed to alert you if certain vehicles
enter the blind spot zone while driving.
Note: The Blind Spot Information System
does not prevent contact with other vehicles
or objects; nor detect parked vehicles,
people, animals or infrastructure (fences,
guardrails, trees). It’ s only designed to alert
you to moving vehicles in the blind spot
zones.
Note: When a vehicle passes quickly
through the blind spot zone, typically fewer
than two seconds, the system does not
trigger.
Using the System
The Blind Spot Information System turns
on when you start the engine and you drive
your vehicle forward above
5 mph
(8 km/h).
For automatic transmissions, the Blind
Spot Information System remains on while
the transmission is in drive (D). If shifted
into reverse (R) or park (P) the Blind Spot
Information System turns off. Once shifted
back into drive (D), the Blind Spot
Information System turns back on when
you drive your vehicle above
5 mph
(8 km/h).

For manual transmissions, the Blind Spot
Information System is on for all gears
except the reverse (R).
Note:
For automatic transmissions, the
Blind Spot Information System does not
function in reverse (R) or park (P).
System Lights and Messages The Blind Spot Information System
illuminates an amber alert indicator in the
outside mirror on the side of your vehicle
the approaching vehicle is coming from.
When the Blind Spot Information System
is alerting on a vehicle and the
corresponding turn signal is ON, the Blind
Spot Information System alert indicator
flashes as an increased warning level.
The alert indicator dims when the system
detects nighttime darkness.
Note:
The alert indicator flashes in case of
an alert and the turn signal is set to that side
at the same time.
System Sensor Blockage WARNING
To help avoid injuries, NEVER use the
Blind Spot Information System as a
replacement for using the interior
and exterior mirrors or looking over your
shoulder before changing lanes. The Blind
Spot Information System is not a
replacement for careful driving. 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 and/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
of a blocked sensor will appear in the
information display. Also the BLIS alert
indicators will remain ON and BLIS will no
longer provide any vehicle warnings. You
can clear the information display warning
but the alert indicators will 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 257). 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.

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.

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
(9 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 will
illuminate and a message will appear in
the information display. See Information
Messages (page 126).
Switching the System Off and On
You can temporarily switch the Blind Spot
Information System off in the information
display. See
General Information (page
110). When the Blind Spot Information
System switches off, you will not receive
alerts and the information display 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 WARNING
To help avoid personal injury, NEVER
use the Cross Traffic Alert system as
a replacement for using the interior
and exterior mirrors and looking over your
shoulder before backing out of a parking
space. Cross Traffic Alert is not a
replacement for careful driving. Note:
When a trailer is detected, Cross
Traffic Alert automatically turns off.
Cross Traffic Alert is designed to warn you
of vehicles approaching from the sides
when the transmission is in reverse (R).
Using the System
Cross Traffic Alert turns on when you start
the engine and you shift into reverse (R).
Once shifted out of reverse (R), Cross
Traffic Alert turns off.
240
F-150 (TFC) Canada/United States of America, enUSA, First Printing Driving Aids

Zone coverage also decreases when
parking at shallow angles. Here, the left
sensor is mostly obstructed; zone coverage
on that side is severely limited.
System Lights, Messages and
Audible Alerts
The Cross Traffic Alert illuminates an
amber alert indicator in the outside mirror
on the side of your vehicle the approaching
vehicle is coming from. Cross Traffic Alert
also sounds an audible alert and a
message appears in the information
display indicating a vehicle is coming from
the right or left. Cross Traffic Alert works
with the reverse sensing system that
sounds its own series of tones. See
Principle of Operation (page 213). The system uses radar sensors that are
located in the tail lamp on each side of
your vehicle. Do not allow mud, snow or
bumper stickers to obstruct these areas,
this can cause degraded system
performance. See
Blind Spot
Information System (page 236). If the
Blind Spot Information System is blocked,
Cross Traffic Alert is also blocked. A Cross
Traffic Alert blocked message appears in
the information display when the
transmission is shifted into reverse (R).
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.
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.

WARNINGS
This system is an extra driving aid. It
does not replace your attention and
judgment, or the need to apply the
brakes. This system does NOT
automatically brake your vehicle. If you fail
to press the brake pedal when necessary,
you may collide with another vehicle. Note:
The system is not a substitute for
safe driving practices.
Note: You must always be aware of the
vehicle and trailer combination and the
surrounding environment.
Note: The system does not detect or
prevent the vehicle or trailer from making
contact with obstacles in the surrounding
environment.
Note: Keep in mind that the front end of
the vehicle swings out when changing the
direction of the trailer.
Note: The system relies on user
measurements to determine sticker
placement and system limits. It is critical to
take the key measurements correctly.
Incorrect measurements can result in the
improper function of the system up to and
including contact between the vehicle and
trailer.
Note: The system limits vehicle speed when
backing up. The system is not a replacement
for proper use of the throttle and brake
pedals.
Principle of Operation
This feature helps you to steer your vehicle
when backing up with a trailer attached.
Turn and hold the control knob in the
direction you want the trailer to go and the
system takes over the steering. This allows
you to focus on checking the mirrors and
operating the brake and accelerator.
Each trailer you use with your vehicle has
to be setup once. You must take care to follow the setup
process accurately, to make sure the
sticker is placed correctly.
Setting Up Pro Trailer Backup
Assist
Note:
Once you have entered a trailer's
information into the system, it is stored for
easy recall. A maximum of 10 trailers can be
added to the system.
Step 1: Position your Vehicle and Trailer
Hitch your conventional trailer to your
vehicle. See Essential Towing Checks
(page 278).
Park your vehicle and hitched trailer on a
level surface.
For best results, make sure that your trailer
rides level with the ground when you hitch
it your vehicle. More information on
selecting your towbar is available in the
Towing section.
See Towing (page 256). Make sure your vehicle and the trailer are
in line with each other. You can do this by
driving straight forward.
Step 2: Follow the Information Display
Prompts
Press the button to turn the system on.
