Restraint Safety System
The restraint safety system provides an
improved overall level of frontal crash
protection to front seat occupants and is
designed to help further reduce the risk of
airbag-related injuries. The system is able
to analyze different occupant conditions
and crash severity before activating the
appropriate safety devices to help better
protect a range of occupants in a variety
of frontal crash situations.
Your vehicle restraint safety system
consists of:
•
Driver and passenger dual-stage airbag
supplemental restraints.
• Front outboard safety belts with
pretensioners, energy management
retractors (first row only), and safety
belt usage sensors.
• Driver seat position sensor.
• Front crash severity sensors.
• Restraints control module with impact
and safing sensors.
• Restraint system warning light and
backup tone.
• The electrical wiring for the airbags,
crash sensor(s), safety belt
pretensioners, front safety belt usage
sensors, driver seat position sensor, and
indicator lights.
How does the restraint safety system
work?
The restraint safety system can adapt the
deployment strategy of your vehicle ’s
safety devices according to crash severity
and occupant conditions. A collection of
crash and occupant sensors provides
information to the restraints control module. During a crash, the restraints
control module may activate the safety
belt pretensioners and/or either one or
both stages of the dual-stage airbag
supplemental restraints based on crash
severity and occupant conditions.
DRIVER AND PASSENGER
AIRBAGS
WARNINGS
Never place your arm or any objects
over an airbag module. Placing your
arm over a deploying airbag can
result in serious arm fractures or other
injuries. Objects placed on or over the
airbag inflation area may cause those
objects to be propelled by the airbag into
your face and torso causing serious injury. Airbags can kill or injure a child in a
child seat. Never place a rear-facing
child seat in front of an active airbag.
If you must use a forward-facing child seat
in the front seat, move the seat upon which
the child seat is installed all the way back. The driver and passenger front airbags will
deploy during significant frontal and near
frontal crashes.
The driver and passenger front airbag
system consists of:
•
Driver and passenger airbag modules.

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(s) weight
• Payload, cargo and luggage
weight
• Aftermarket equipment
weight.
3. This equals the maximum
loaded trailer weight for this
combination.
Note: The trailer tongue load
figures into the payload for your
vehicle. Reduce the total payload
by the final trailer tongue weight.
Consult an authorized dealer to
determine the maximum trailer
weight allowed for your vehicle if
you are not sure. Maximum GCWR

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•
Do not tow a trailer until you drive your
vehicle at least 1000 miles (1600
kilometers).
• 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.
See Load limits in the Load Carrying
chapter for load specification terms found
on the tire label and Safety Compliance
label and instructions on calculating your
vehicle's load.
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.

Hitches WARNING
The trailer hitch on this vehicle is part
of the vehicle rear crash safety
structure. Do not remove the trailer
hitch. Failure to follow this warning could
compromise vehicle crash structure and
increase the risk of injury in a rear end
crash. Do not use a hitch that either clamps onto
the bumper or attaches to the axle.
Distribute the trailer load so 10-15% of the
total trailer weight is on the tongue.

The controller shows gain setting, output
bar graph, and trailer connectivity status
in the information display. They appear in
the information display as follows:
•
Trailer Brake Controller Gain (without
trailer connected): Shows the current
gain setting during a given ignition cycle
and when adjusting the gain. This also
displays if you use the manual control
lever or make gain adjustments with
no trailer connected.
• Trailer Brake Controller Gain Output:
Displays when you push your vehicle's
brake pedal, or upon use of the manual
control. Bar indicators illuminate in the
information display to indicate the
amount of power going to the trailer
brakes relative to the brake pedal or
manual control input. One bar indicates
the least amount of output; six bars
indicate maximum output.
• Trailer Connected: Displays when the
system senses a correct trailer wiring
connection (a trailer with electric trailer
brakes) during a given ignition cycle.
• Trailer Disconnected: Displays,
accompanied by a single audible time,
when the system senses a trailer
connection and then a disconnection,
either intentional or unintentional,
during a given ignition cycle. It also
displays if a truck or trailer-wiring fault
occurs causing the trailer to appear
disconnected. This message can also
display if you use the manual control
lever without a trailer connected. After
disconnecting the trailer connector,
press the brake pedal for
approximately five seconds to allow
the system to detect and update the
trailer status. B: Manual control lever: Slide the control
lever to the left to turn on the trailer's
electric brakes independent of the tow
vehicle's. See the following Procedure for
adjusting gain section for instructions on
proper use of this feature. If you use the
manual control while the brake is also
applied, the greater of the two inputs
determines the power sent to the trailer
brakes.
• Stop lamps: Using the manual control
lever illuminates both the trailer brake
lamps and your vehicle brake lamps
except the center high-mount stop
lamp, if you make the proper electrical
connection to the trailer. Pressing your
vehicle brake pedal also illuminates
both trailer and vehicle brake lamps.
Procedure for Adjusting Gain
Note: Only perform this procedure in a
traffic-free environment at speeds of
approximately 20-25 mph (30-40 km/h).
The gain setting sets the trailer brake
controller for the specific towing condition.
You should change the setting as towing
conditions change. Changes to towing
conditions include trailer load, vehicle load,
road conditions and weather.
The gain should be set to provide the
maximum trailer braking assistance while
making sure the trailer wheels do not lock
when using the brakes. Locked trailer
wheels may lead to trailer instability.
1. Make sure the trailer brakes are in good
working condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary.
2. Hook up the trailer and make the electrical connections according to the
trailer manufacturer's instructions.
3. When you plug in a trailer with electric or electric-over-hydraulic brakes, a
message confirming connection
appears in the information display.
211
Expedition (TB7) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Towing

4. Use the gain adjustment (+ and -)
buttons to increase or decrease the
gain setting to the desired starting
point. A gain setting of 6.0 is a good
starting point for heavier loads.
5. In a traffic-free environment, tow the trailer on a dry, level surface at a speed
of 20-25 mph (30-40 km/h) and
squeeze the manual control lever
completely.
6. If the trailer wheels lock up, indicated by squealing tires, reduce the gain
setting. If the trailer wheels turn freely,
increase the gain setting. Repeat Steps
5 and 6 until the gain setting is at a
point just below trailer wheel lock-up.
If towing a heavier trailer, trailer wheel
lock-up may not be attainable even
with the maximum gain setting of 10.
Explanation of Information Display
Warning Messages
Note: An authorized dealer can diagnose
the trailer brake controller to determine
exactly which trailer fault has occurred.
However, your Ford warranty does not cover
this diagnosis if the fault is with the trailer.
A message indicating a trailer brake
module fault may display in response to
faults sensed by the trailer brake controller,
accompanied by a single tone. If this
message appears, contact an authorized
dealer as soon as possible for diagnosis
and repair. The controller may still
function, but performance may be
degraded.
A message indicating a trailer wiring fault
may display when there is a short circuit
on the electric brake output wire. If this
message displays, accompanied by a
single tone, with no trailer connected, the
problem is with your vehicle wiring
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.
212
Expedition (TB7) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Towing

•
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, turn signals 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. When Towing a Trailer
•
Do not drive faster than 70 mph (113
km/h) during the first 500 miles (800
kilometers).
• Do not make full-throttle starts.
• Check your hitch, electrical connections
and trailer wheel lug nuts thoroughly
after you have traveled 50 miles (80
kilometers).
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position P to aid engine and
transmission cooling and to help A/C
performance.
• Turn off the speed control with heavy
loads or in hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If your transmission is equipped with a
Grade Assist or Tow/Haul feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
• If your vehicle is equipped with
AdvanceTrac with RSC, this system
may turn on during typical cornering
maneuvers with a heavily loaded trailer.
This is normal. Turning the corner at a
slower speed while towing may reduce
this tendency.
• If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your rear axle with synthetic
gear lubricant (if the axle is not already
filled with it). See Capacities and
Specifications (page 304).
213
Expedition (TB7) Canada/United States of America, enUSA, Edition date: 03/2016, First Printing Towing

•
Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
1. Turn the steering wheel to point your vehicle tires away from traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in position P.
4. Place wheel chocks in front and back of the trailer wheels. (Chocks not
included with vehicle.)
Your vehicle may be equipped with a
temporary or conventional spare tire. A
"temporary" spare tire is different in size
(diameter or width), tread-type
(All-Season or All Terrain) or is from a
different manufacturer than the road tires
on your vehicle. Consult information on the
tire label or Safety Compliance label for
limitations when using.
Launching or Retrieving a Boat or
Personal Watercraft (PWC)
Note: Disconnect the wiring to the trailer
before
backing the trailer into the water.
Note: Reconnect the wiring to the trailer
after
removing the trailer from the water.
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than 6 inches (15 centimeters) above
the bottom edge of the rear bumper. Exceeding these limits may allow water to
enter vehicle components:
•
Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
TOWING POINTS
(If Equipped) WARNINGS
Using recovery hooks is dangerous
and should only be done by a person
familiar with proper vehicle recovery
safety practices. Improper use of recovery
hooks may cause hook failure or separation
from the vehicle and could result in serious
injury or death. Always slowly remove the slack from
the recovery strap prior to pulling.
Failure to do so can introduce
significantly higher loads which can cause
the recovery hooks to break off, or the
recovery strap to fail which can cause
serious injury or death. Never link two straps together with
a clevis pin. These heavy metal
objects could become projectiles if
the strap breaks and can cause serious
injury or death. Your vehicle comes equipped with
frame-mounted front recovery hooks.
These hooks should never have a load
applied to them greater than the gross
vehicle weight rating of your vehicle.
