FORD EXPEDITION 2015 3.G Owners Manual

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 your vehicle’s electrical system may not include the
wiring connector needed to use 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.

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.
For load specification terms found on the tire label and Safety
Compliance label and for instructions on calculating your vehicle’s load,
refer toLoad limitin theLoad Carryingchapter.
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. If your vehicle has a
trailer towing package, it may have
a 7–pin connector. Some 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 clamps onto your vehicle’s bumper. Use a
load-carrying hitch. You must distribute the load in your trailer so that
10–15% of the total weight of the trailer is on the tongue.
Integrated Hitch Rating
WARNING:Towing trailers beyond the maximum tongue weight
exceeds the limit of the towing system and could result in vehicle
structural damage, loss of vehicle control and personal injury.
The standard integrated hitch has two ratings depending on mode of
operation:
•Weight-carrying mode requires a draw bar and hitch ball. The draw
bar supports all the vertical tongue load of the trailer.
•Weight-distributing mode requires an aftermarket weight-distributing
system, which includes draw bar, hitch ball, spring bars and snap-up
brackets. This system distributes the vertical tongue load of the trailer
between the truck and the trailer.
Mode Maximum trailer
weightMaximum tongue
weight
Weight-carrying 6000 lb (2721 kg) 600 lb (272 kg)
Weight-distributing 9200 lb (4173 kg) 920 lb (417 kg)
Note:These are hitch ratings only. Actual vehicle ratings are dependent
on engine, transmission and axle combinations.
Weight-distributing Hitch – Vehicles without Automatic Leveling
Suspension
WARNING:Do not adjust a weight-distributing hitch to any
position where the rear bumper of the vehicle is higher than it
was 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 your vehicle, without the trailer, on a level surface.
2. Measure the height of the top of your vehicle’s front wheel opening
on the fender. This is H1.
3. Attach the trailer to your vehicle without the weight-distributing bars
connected.
4. Measure the height of 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 the front fender is approximately halfway between H1
and H2.
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.
Once 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.
Weight-distributing Hitch – Vehicles with Automatic Leveling
Suspension
WARNING:Do not adjust a weight-distributing hitch to any
position where the rear bumper of the vehicle is higher than it
was 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.
Note:
If you do not move the loaded vehicle for approximately 12 hours, the
leveling system may bleed down to a lower height. This can be especially
apparent if you leave a trailer attached to the parked vehicle for long
periods. You must drive your vehicle in order to re-level the suspension.
When connecting a trailer to a vehicle with automatic leveling suspension
using a weight-distributing hitch, always use the following procedure:
1.
Load the interior of the vehicle to a weight similar to that which you
intend to carry when towing. This includes things such as passenger
weight and cargo.
2. Drive the vehicle for approximately 2 miles (3 kilometers) to re-level
the suspension.
3. Park your vehicle, without the trailer, on a level surface.
4. Measure the height to the top of your vehicle’s front wheel opening on
the fender. This is H1.

5. Attach the trailer to your vehicle without the weight-distributing bars
connected.
6. Make sure you securely attach and lock the trailer tongue to the hitch.
7. Install safety chains, lighting, and trailer brake controls as required by
law or the trailer manufacturer.
8. Drive the vehicle and trailer at 20–25 mph (32–40 km/h) for
approximately 2 miles (3 kilometers) to re-level the suspension.
9. Park your vehicle and trailer on a level surface.
10. Measure the height to the top of your vehicles front wheel opening on
the fender a second time. This is H2.
11. Install and adjust the tension in the weight distributing bars so that
the height of the front fender is approximately halfway between H1
and H2.
12. Check that the trailer is level or slightly nose down toward the vehicle.
If it is not, remove the trailer, adjust the ball height accordingly, and
repeat Steps 5 -11.
Once 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 trailer’s safety chains to the frame or hook retainers
of your vehicle hitch.
To connect the trailer’s safety chains, 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.
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 1500 pounds
(680 kilograms) when loaded.
Integrated Trailer Brake Controller (If Equipped)
WARNING:The Ford TBC has been verified to be compatible
with trailers having electric-actuated drum brakes (one to four
axles) and some electric-over-hydraulic (EOH) brakes. It will not
activate hydraulic surge-style trailer brakes. It is the responsibility of
the customer to ensure that the trailer brakes are adjusted
appropriately, functioning normally and all electric connections are
properly made. Failure to do so may result in loss of vehicle control,
crash or serious injury.
When used properly, the trailer brake controller assists in smooth and
effective trailer braking by powering the trailer’s electric or
electric-over-hydraulic brakes with a proportional output based on the
towing vehicle’s brake pressure.
Ford has tested the trailer brake controller to be compatible with several
major brands of electric-over-hydraulic trailer brakes. Contact an
authorized dealer for information on which brands you can use.
The controller user interface consists of the following:
A.+ and - (Gain adjustment buttons):Pressing these buttons adjusts
the controller’s power output to the trailer brakes in 0.5 increments. You
can increase the gain setting to 10.0 (maximum trailer braking) or
decrease it to 0 (no trailer braking). The gain setting displays in the
message center as follows: TBC GAIN = XX.X.
The controller shows gain setting, output bar graph, and trailer
connectivity status in the information display. They appear in the
Towing255
2015 Expedition(exd)
Owners Guide gf, 1st Printing, July 2014
USA(fus)

information display as follows:
•TBC GAIN = XX.X NO TRAILER: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.
•TBC GAIN = XX.X OUTPUT=//////:Displays when you push
your vehicle’s brake pedal, or when you use 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 chime, 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.
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 brakes. See
the followingProcedure for adjusting gainsection 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,TRAILER CONNECTEDappears in the information display.
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 doesnotcover this diagnosis if the fault is with the trailer.
TRAILER BRAKE MODULE FAULT:Displays in response to faults
sensed by the trailer brake controller, accompanied by a single chime. 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.
WIRING FAULT ON TRAILER:Displays when there is a short circuit
on the electric brake output wire. If theWIRING FAULT ON TRAILER
message displays, accompanied by a single chime, with no trailer
Towing257
2015 Expedition(exd)
Owners Guide gf, 1st Printing, July 2014
USA(fus)

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 theWorkshop 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 turn the engine off, the controller output is disabled and
the display and module shut down. The controller module and display
turn on when you turn 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 a fire. Contact an 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 positionPto aid engine and transmission cooling and
to help air conditioning 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.
