2018 FORD EXPEDITION brake light

Action
Cause
Do not use the system in these conditions
because it may not detect any vehicles
ahead.
Water, snow or ice on the surface of the
road may interfere with the radar signals.
Wait a short time or switch to normal cruise
control.
You are in a desert or remote area with no
other vehicles and no roadside objects.
Due to the nature of radar technology, it is possible to get a blockage warning with no
actual block. This happens, for example, when driving in sparse rural or desert
environments. A false blocked condition either self clears, or clears after you restart your
vehicle.
Switching to Normal Cruise
Control WARNING: Normal cruise control
will not brake when your vehicle is
approaching slower vehicles. Always be
aware of which mode you have selected
and apply the brakes when necessary.
You can change from adaptive cruise
control to normal cruise control through
the information display. The cruise control indicator light
replaces the adaptive cruise
control indicator light if you
select normal cruise control. The gap
setting does not display, and the system
does not respond to lead vehicles.
Automatic braking remains active to
maintain set speed.

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
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 (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:
The system does not
detect vehicles that are driving in a
different direction, cyclists or animals.
Failure to take care may result in the loss
of control of your vehicle, serious
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: In situations where the
vehicle camera has limited detection
capability, this may reduce system
performance. These situations include
but are not limited to direct or low
sunlight, vehicles at night without tail
lights, unconventional vehicle types,
pedestrians with complex backgrounds,
257
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- Driving Aids

running pedestrians, partly obscured
pedestrians, or pedestrians that the
system cannot distinguish from a group.
Failure to take care may result in the loss
of control of your vehicle, serious
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: 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.
Note: The Pre-Collision Assist system
automatically disables when you select 4X4
LOW
or when you manually disable
AdvanceTrac ™.
Distance Indication and Alert
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.

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 314).
Some vehicles may have the
ability to modify trailer towing
features. See Towing (page 274).
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
268).
You can also find information in
the
RV & Trailer Towing Guide
available at your authorized
dealer, or online.

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
274
).
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 36.5 feet² (3.39
meters²) if your vehicle is equipped
with the standard towing package,
or 60 feet² (5.57 meters²) if your
vehicle is equipped with the
optional 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: For high altitude operation,
reduce the gross combined weight
by 2% per
1,000 ft (300 m)
starting at the 1,000 ft (300 m)
elevation point. 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.
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
following chart.
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
following chart.
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 268).
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.

Trailer Hitch Cover
Your vehicle has a removable trailer hitch
cover. To remove the trailer hitch cover: 1. Grab the trailer hitch cover at the
bottom and pull towards the rear of
the vehicle until the bottom of the
trailer hitch cover unsnaps from the
bumper.

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.
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.
289
Expedition (TB8) Canada/United States of America, enUSA, Edition date: 201708, Third-Printing- TowingE265060

between the trailer brake controller and
the 7-pin connector at the bumper. If the
message only displays with a trailer
connected, the problem is with the trailer
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. Ford 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, direction indicators and hazard lights
are working.
