Enter length of trailer:
The default setting is 18 ft (5.5 m). Toggling
up or down using the menu buttons
increases or decreases the measurement by
3 ft (1 m)
. Select a length that 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), toggle the length in
the menu to 27 ft (8.2 m). When you enter
the length of the trailer, the system setup is
saved.
Note: If the trailer is a bike rack or cargo
rack with electrical lighting, enter a length
of
3 ft (1 m). Cross Traffic Alert remains on
for trailers with a length of 3 ft (1 m) or less.
Note: Proper measurement and
measurement entry is required for the
system to function as designed. System Operation
When you connect a trailer to your vehicle,
the trailer set up menu appears in the
information display. This menu allows you to
set up a new trailer or choose from a
previously set up trailer. A warning message
appears and the system turns off if you do
not choose or add a new trailer.
Note:
The warning message may not appear
until your vehicle speed reaches
22 mph
(35 km/h).
If you select a trailer in the information
display before connecting a trailer to your
vehicle, the system loads the configuration
for the selected trailer. When a trailer is
connected, a warning message appears.
Note: A second warning message may
appear stating that the Cross Traffic Alert
system has turned off. The Blind Spot
Information System with Trailer Tow
continues to function normally in this
situation.
Note: The system remembers the last
selected trailer set up when you start your
vehicle. Trailer Considerations
The system is designed to work with a trailer
with a front width of 8.5 ft (2.6 m) or less, and
a total length from the trailer hitch ball to the
rear of the trailer of
33 ft (10.1 m) or less.
Some trailers may cause a slight change in
system performance:
• Large box trailers may cause false alerts
to occur when driving next to
infrastructures or near parked cars. A
false alert may also occur while making
a 90 degree turn.
• Trailers that have a width greater than
8.5 ft (2.6 m)
at the front and have a total
length greater than 20 ft (6 m) may cause
delayed alerts when a vehicle is passing
at high speeds.
• Box trailers that have a width greater than
8.5 ft (2.6 m)
at the front may cause early
alerts when you pass a vehicle.
• Clam shell or V-Nose box trailers with a
width greater than
8.5 ft (2.6 m) at the
front may cause delayed alerts when a
vehicle traveling the same speed as your
vehicle merges lanes.

PRE-COLLISION ASSIST
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:
The system does not
detect vehicles that are driving in a
different direction, cyclists or animals.
Apply the brakes when necessary. Failure
to follow this instruction could result in the
loss of control of your vehicle, personal
injury or death. WARNING:
The system does not
operate during hard acceleration or
steering. Failure to take care may lead to
a crash or personal injury. WARNING:
The system may fail or
operate with reduced function during cold
and severe weather conditions. Snow, ice,
rain, spray and fog can adversely affect the
system. Keep the front camera and radar
free of snow and ice. Failure to take care
may result in the loss of control of your
vehicle, serious personal injury or death. WARNING:
Some situations and
objects prevent hazard detection. For
example low or direct sunlight, inclement
weather, unconventional vehicle types, and
pedestrians. Apply the brakes when
necessary. Failure to follow this instruction
could result in the loss of control of your
vehicle, personal injury or death. WARNING:
The system cannot help
prevent all crashes. Do not rely on this
system to replace driver judgment and the
need to maintain a safe distance and
speed. Using the Pre-Collision Assist System
The Pre-Collision Assist system is active at
speeds above approximately 3 mph (5 km/h)
and pedestrian detection is active at speeds
up to
50 mph (80 km/h).
If your vehicle is rapidly approaching another
stationary vehicle, a vehicle traveling in the
same direction as yours, or a pedestrian
within your driving path, the system provides
three levels of functionality:
1. Alert
2. Brake Support
3. Active Braking
Alert
: When active, a flashing visual warning
appears and an audible warning tone
sounds.
298
Navigator (TB9) Canada/United States of America, enUSA, First-Printing Driving AidsE156130

Brake Support: The system helps reduce
the impact speed by preparing the brakes
for rapid braking. Brake support does not
apply the brakes. If you press the brake
pedal, the system could apply additional
braking up to maximum braking force, even
if you lightly press the brake pedal.
Active Braking
: Active braking may activate
if the system determines that a collision is
imminent. The system may help the driver
reduce impact damage or avoid the crash
completely.
Note: Brake Support and Active Braking are
active at speeds up to 74.6 mph (120 km/h).
If the vehicle has a radar sensor or Adaptive
Cruise Control, then Brake Support and
Active Braking are active up to the maximum
speed of the vehicle.
Note: The system disables when you select
the Slow Climb or Deep Conditions drive
modes. Note:
If you perceive Pre-Collision Assist
alerts as being too frequent or disturbing,
then you can reduce the alert sensitivity,
though the manufacturer recommends using
the highest sensitivity setting where possible.
Setting lower sensitivity would lead to fewer
and later system warnings.
Distance Indication and Alert (If Equipped)
Distance Indication and Alert is a function
that provides you with a graphical indication
of the time gap to other preceding vehicles
traveling in the same direction. The Distance
Indication and Alert screen in the information
display shows one of the following graphics. If the time gap to a preceding vehicle is
small, a red visual indication appears.
Note:
Distance Indication and Alert
deactivates, and the graphics do not display
when adaptive cruise control is active.

TOWING A TRAILER
WARNING: 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. WARNING:
Do not exceed the
GVWR or the GAWR specified on the
certification label.
Note: See
Recommended Towing
Weights (page 327).
Your vehicle may have electrical items,
such as fuses or relays, related to
towing.
See Fuses (page 360). 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.
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 and load capacity. 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 309).
You can also find information in the
RV
& Trailer Towing Guide available at your
authorized dealer, or online.

Calibration
The system monitors various vehicle
parameters to ensure your vehicle is being
driven straight and the trailer straight behind
your vehicle. Any steering input or trailer
movement will pause the calibration.
For best results:
•
Use a long, straight, smooth and level
road when attempting to calibrate.
• Drive straight forward.
• Drive between 4 mph (6 km/h) and
24 mph (39 km/h).
System Operation
The following warnings or difficulties may
occur during feature operation. Tips to
resolve them are listed below. The system is not available:
•
The system relies on many sub-systems
in your vehicle to operate correctly. If
those sub-systems are not operating
correctly the system may not be
available.
• Low battery voltage is a condition which
will prevent the system from operating.
Please make sure the battery is correctly
charged if the system is not available.
• You may need to drive your vehicle
straight forward above 25 mph (40 km/h)
before the system is available again.
• If the message still displays take your
vehicle to an authorized dealer for
service.
Sticker lost:
• If the system cannot initially find the
sticker, it may be necessary for you to
change the lighting conditions by moving
the vehicle and trailer or waiting until
conditions change.
• Check for the following if you receive the
lost sticker message while using the
system. •
Stop your vehicle as soon as the
message displays.
• Make sure the sticker is visible and the
pattern is discernable in the rear view
camera image.
• Clean the sticker and camera to make
sure they are unobstructed.
• Clean the lens with a soft, lint-free cloth
and water.
• Clean the sticker with isopropyl rubbing
alcohol sprayed directly onto the sticker,
and then wipe clean with a soft cloth.
• Remove any items that may be blocking
the view of the sticker. Depending on
your trailer configuration and any
equipment mounted to your trailer it is
possible for the sticker to be blocked
from view of the camera as it rotates on
the hitch ball but not be blocked during
setup. Remove the obstruction if
possible. It will be necessary to remove
the sticker from it’ s current location if the
obstruction cannot be cleared and place
a new sticker that will be visible to the
camera in all positions of the trailer
behind your vehicle.

TRAILER SWAY CONTROL (IF EQUIPPED)
WARNING: Turning off trailer sway
control increases the risk of loss of vehicle
control, serious injury or death. Ford does
not recommend disabling this feature
except in situations where speed reduction
may be detrimental (such as hill climbing),
the driver has significant trailer towing
experience, and can control trailer sway
and maintain safe operation.
Note: This feature does not prevent trailer
sway, but reduces it once it begins.
Note: This feature cannot stop all trailers
from swaying.
Note: In some cases, if vehicle speed is too
high, the system may activate multiple times,
gradually reducing vehicle speed. This feature applies your vehicle brakes at
individual wheels and, if necessary, reduces
engine power. If the trailer begins to sway,
the stability control light flashes and the
message TRAILER SWAY REDUCE SPEED
appears in the information display. The first
thing to do is slow your vehicle down, then
pull safely to the side of the road and check
for proper tongue load and trailer load
distribution.
See Load Carrying (page 309).
RECOMMENDED TOWING
WEIGHTS
Note: Do not exceed the trailer weight
for your vehicle configuration listed in
the chart below.
Note: Make sure to take into
consideration trailer frontal area. Do not
exceed 55 ft² (5.11 m²) if your vehicle has
the standard towing package, or 60 ft²
(5.57 m²) if your vehicle has the heavy
duty package. Note:
Exceeding this limitation may
significantly reduce the performance of
your towing vehicle. Selecting a trailer
with a low aerodynamic drag and
rounded front design helps optimize
performance and fuel economy.
Note: Your vehicle could have reduced
performance when operating at high
altitudes, and when heavily loaded or
towing a trailer. When driving at
elevation, in order to match driving
performance as perceived at sea level,
reduce gross vehicle weight and gross
combination weight by 2% per
1,000 ft
(300 m) of elevation.
Note: Certain states require electric
trailer brakes for trailers over a specified
weight. Be sure to check state
regulations for this specified weight. The
maximum trailer weights listed may be
limited to this specified weight, as the
vehicle ’s electrical system may not
include the wiring connector needed to
activate electric trailer brakes.

Note:
These are hitch ratings only. Actual
vehicle ratings are dependent on engine,
transmission and axle combinations.
Weight-distributing Hitch WARNING: Do not adjust the spring
bars so that your vehicle's rear bumper is
higher than before attaching the trailer.
Doing so will defeat the function of the
weight-distributing hitch, which may cause
unpredictable handling, and could result
in serious personal injury.
When hooking-up a trailer using a
weight-distributing hitch, always use the
following procedure:
1. Park the loaded vehicle, without the trailer, on a level surface.
2. Measure the height to the top of your vehicle's front wheel opening on the
fender. This is H1.
3. Attach the loaded trailer to your vehicle without the weight-distributing bars
connected. 4. Measure the height to the top of your
vehicle's front wheel opening on the
fender a second time. This is H2.
5. Install and adjust the tension in the weight-distributing bars so that the height
of your vehicle's front wheel opening on
the fender is approximately half the way
down from H2, toward H1.
6. Check that the trailer is level or slightly nose down toward your vehicle. If not,
adjust the ball height accordingly and
repeat Steps 2-6.
When the trailer is level or slightly nose down
toward the vehicle:
• Lock the bar tension adjuster in place.
• Check that the trailer tongue securely
attaches and locks onto the hitch.
• Install safety chains, lighting and trailer
brake controls as required by law or the
trailer manufacturer. Safety Chains
Note:
Do not attach safety chains to the
bumper. Always connect the safety chains
to the frame or hook retainers of your trailer
hitch.
Install trailer safety chains to the trailer hitch
as recommended by the manufacturer. Cross
the chains under the trailer tongue and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground. If the trailer safety chain hook has a latch,
make sure the latch fully closes.

Points to Remember
Note:
Do not attempt removal of the trailer
brake controller without consulting the
Workshop Manual. Damage to the unit may
result.
• Adjust gain setting before using the
trailer brake controller for the first time.
• Adjust gain setting, using the procedure
above, whenever road, weather and
trailer or vehicle loading conditions
change from when the gain was initially
set.
• Only use the manual control lever for
proper adjustment of the gain during
trailer setup. Misuse, such as application
during trailer sway, could cause instability
of trailer or tow vehicle.
• Avoid towing in adverse weather
conditions. The trailer brake controller
does not provide anti-lock control of the
trailer wheels. Trailer wheels can lock up
on slippery surfaces, resulting in reduced
stability of trailer and tow vehicle. •
The trailer brake controller is equipped
with a feature that reduces output at
vehicle speeds below 11 mph (18 km/h)
so trailer and vehicle braking is not jerky
or harsh. This feature is only available
when applying the brakes using your
vehicle's brake pedal, not the controller.
• The controller interacts with the brake
control system and powertrain control
system of your vehicle to provide the
best performance on different road
conditions.
• Your vehicle's brake system and the
trailer brake system work independently
of each other. Changing the gain setting
on the controller does not affect the
operation of your vehicle's brakes
whether you attach a trailer or not. •
When you switch the engine off, the
controller output is disabled and the
display and module shut down. The
controller module and display turn on
when you switch the ignition on.
• The trailer brake controller is only a
factory-installed or dealer-installed item.
Lincoln is not responsible for warranty or
performance of the controller due to
misuse or customer installation.
Trailer Lamps WARNING: Never connect any trailer
lamp wiring to the vehicle's tail lamp wiring;
this may damage the electrical system
resulting in fire. Contact your authorized
dealer as soon as possible for assistance
in proper trailer tow wiring installation.
Additional electrical equipment may be
required.
Trailer lamps are required on most towed
vehicles. Make sure all running lights, brake
lights, turn signals and hazard lights are
working.
