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
system can support is 8.5 ft (2.6 m).
Note: You do not need to enter an exact
trailer width measurement. You only need
to confirm that the width of the trailer 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
system 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 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.

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.
Steering Tips
If the steering wanders or pulls, check for:
•
Correct tire pressures.
• 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.
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. Additionally, 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. 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, pedestrians at night,
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 is designed to provide 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.
Brake Support
: The system is designed
to help reduce the impact speed by
preparing the brakes for rapid braking.
Brake support does not automatically
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
75 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: 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 leads to
fewer and later system warnings.
Note: The system disables when you select
4x4 low, sand mode, mud/ruts mode or
when you manually disable AdvanceTrac ™.
Distance Indication and Alert
(If
Equipped)
This 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.

For the short wheel base system, it is
necessary for the second panel located
toward the front of the vehicle to be raised
up when the seats are folded down.
For the long wheel base system, it is
necessary for the second panel located
toward the front of the vehicle to be raised
up.
Note:
Before moving the board into the
shelf position, you may need to flip down
the hooks.
Note: Do not put more than 50 lb (22 kg)
on shelf.
Rear Barrier (Bulkhead Position) To move the board into the rear barrier or
bulkhead position, lift the board and move
it to the vertical position. Once the board
is vertical, insert the rearward facing nubs
into the hooks on either side.
Note:
Before moving the board into the rear
barrier or bulkhead position, you may need
to flip down the hooks.
CARGO NETS WARNING:
This net is not designed
to restrain objects during a collision or
heavy braking.
The cargo net secures lightweight objects
in the cargo area. 1.
Fold down the hooks on the top of the
rear quarter trim panel. 2. Attach the loop end of the net to the
upper hook. Use one prong on the hook
for the net attachment. 3. Attach the bottom of the net to the
lower anchor point.

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.
Your vehicle may have electrical
items, such as fuses or relays,
related to towing. See
Fuses
(page 325).
Some vehicles may have the
ability to modify trailer towing
features. See Towing (page
285).
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
279).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

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 prevents 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 is necessary
to remove the sticker from its current
location if the obstruction cannot be
cleared and place a new sticker that is
visible to the camera in all positions of
the trailer behind your vehicle.
• Placing the sticker on a surface angled
away from the vehicle reduces
performance. Use a drawbar that
positions the trailer level to the ground
when attached to vehicle. This typically
provides a level surface to mount the
sticker. Place the sticker on a bracket
or other object when no level surface
is available.
• Make sure the entire sticker is on a flat
surface that is completely visible to the
camera. Do not fold the sticker over an
edge on the trailer frame. This can
degrade performance.
• Shadows on the sticker may effect
tracking performance under some
lighting conditions. Moving the sticker
to another location within the allowed
placement area may improve
performance. Use the change sticker
option in your Towing menu if you
move the sticker.

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 Towing (page
285
).
RECOMMENDED TOWING
WEIGHTS
Note: Do not exceed the trailer
weight for your vehicle
configuration listed in the chart
that follows.
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: Your vehicle could have
reduced performance when
operating at high altitudes and
when heavily loaded or towing a
trailer. When driving at elevation,
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. This specified
weight could limit the maximum
trailer weights, as the vehicle ’s
electrical system may not include
the wiring connector needed to
activate electric trailer brakes.
Your vehicle may tow a trailer
provided the maximum trailer
weight is less than or equal to the
maximum trailer weight listed for
your vehicle configuration on the
chart that follows.
To calculate the maximum loaded
trailer weight for your vehicle:
1. Start with the gross combined weight rating for your vehicle
model and axle ratio. See the
chart that follows.
2. Subtract all of the following
that apply to your vehicle:
•Vehicle curb weight.
• Hitch hardware weight, such
as a draw bar, ball, locks or
weight distributing.
• Driver weight.
• Passenger weight.
• Payload, cargo and luggage
weight.
• Aftermarket equipment
weight.
3. This equals the maximum
loaded trailer weight for this
combination.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•
Do not tow a trailer until you drive your
vehicle at least 1,000 mi (1,600 km).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the proper
installation and adjustment
specifications.
• Service your vehicle more frequently if
you tow a trailer. See your scheduled
maintenance information.
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
For load specification terms found on the
tire label and Safety Compliance label and
instructions on calculating your vehicle's
load,
See Load Limit (page 279).
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Trailer Towing Connector
(Vehicles with a Trailer Towing
Package and 7 –Pin Connector) When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions. Some seven-position
connectors may have the SAE J2863 logo,
which confirms that it is the proper wiring
connector and works correctly with your
vehicle.

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.
Trailer Brakes
WARNING: Do not connect a
trailer's hydraulic brake system directly
to your vehicle's brake system. Your
vehicle may not have enough braking
power and your chances of having a
collision greatly increase.
Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Separate functioning brake systems
are required for safe control of towed
vehicles and trailers weighing more
than 1,500 lb (680 kg) when loaded.
301
Expedition (TB8) Canada/United States of America, enUSA, First-Printing TowingE265060

wiring. Consult your trailer dealer for
assistance. This can be a short to ground
such as a chaffed wire, short to voltage
such as a pulled pin on trailer emergency
breakaway battery, or the trailer brakes
may be drawing too much current.
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. We are 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, direction indicators and hazard lights
are working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
