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 installed properly and adjusted to the manufacturer’s
specifications. The trailer brakes must meet local and Federal
regulations.
The braking system of the tow vehicle is rated for operation at
the GVWR not GCWR.
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 TBC assists in smooth and effective trailer
braking by powering the trailer’s electric or EOH brakes with a
proportional output based on the towing vehicle’s brake pressure.
Your vehicle may be equipped with a fully integrated electronic trailer
brake controller (TBC). When used properly, the TBC helps ensure
smooth and effective trailer braking by powering the trailer’s electric
brakes with a proportional output based on the towing vehicle’s brake
pressure.
The Ford TBC has been tested to be compatible with several major
brands of electric-over-hydraulic trailer brakes; contact your authorized
dealer for information on which brands can be used.

The TBC user interface consists of the following:
A.+/- (GAIN adjustment buttons):Pressing these buttons adjusts the
TBC’s power output to the trailer brakes (in 0.5 increments). The GAIN
setting can be increased to a maximum of 10.0 or decreased to a
minimum of 0 (no trailer braking). Pressing and holding a button raises
or lowers the setting continuously. The GAIN setting displays in the
message center as follows: TBC GAIN = XX.X.
The controller is designed to display three items of information in the
information display. These are: GAIN setting, output bar graph, and
trailer connectivity status. They appear in the 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 during manual activation without a trailer connected or when
GAIN adjustments are made with no trailer connected.
•TBC GAIN = XX.X OUTPUT=//////:Displays when the vehicle’s
brake pedal is pushed, or when the manual control is activated. 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 indicates maximum output.
•TRAILER CONNECTED:Displays when a correct trailer wiring
connection (a trailer with electric trailer brakes) has been sensed
during a given ignition cycle.
•TRAILER DISCONNECTED:Displays, accompanied by a single
audible chime, when a trailer connection was determined and then a
disconnection (either intentionally or unintentionally), has been
sensed 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 during manual activation without a
trailer connected.

B.Manual control lever:Slide the control lever to the left to activate
power to 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 the manual control is
activated while the brake is also applied, the greater of the two inputs
determines the power sent to the trailer brakes.
•Stop lamps:Activating the manual control lever illuminates both the
trailer brake lamps and the tow vehicle brake lamps except the
center high-mount stop lamp (if the proper electrical connection has
been made to the trailer). Pressing the vehicle brake pedal also
illuminates both trailer and vehicle brake lamps.
Procedure for Adjusting GAIN
Note:This should only be performed in a traffic-free environment at
speeds of approximately 20–25 mph (30–40 km/h).
The GAIN setting is used to set the TBC for the specific towing
condition and should be changed 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
braking. 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 a trailer with electric or EOH brakes is plugged in, TRAILER
CONNECTED appears in the information display.
4. Use the GAIN adjustment (+/-) 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:Your TBC can be diagnosed by your authorized dealer to
determine exactly which trailer fault has occurred. However, if the fault
is with the trailer this diagnosis isnotcovered under your Ford
warranty.
TRAILER BRAKE MODULE FAULT:Displays in response to faults
sensed by the TBC (accompanied by a single chime). If this message is
displayed, please contact your authorized dealer as soon as possible for
diagnosis and repair. The TBC may still function, but performance may
be degraded.
WIRING FAULT ON TRAILER:Displays when a short circuit on the
electric brake output wire has occurred. If theWIRING FAULT ON
TRAILERmessage is displayed and accompanied by a single chime,
with no trailer connected, the problem is with the vehicle wiring between
the TBC to the 7–pin connector at the bumper. If the message is only
displayed with a trailer connected, the problem is related to the trailer
wiring. Consult your trailer dealer for assistance. This can be a short to
ground (i.e., chaffed wire), short to voltage (i.e., pulled pin on trailer
emergency break-away battery) or the trailer brakes may be drawing too
much current.
Points to Remember
Note:Do not attempt removal of the TBC without consulting the
Workshop Manual.Damage to the unit may result.
•Adjust GAIN setting before using the TBC for the first time.
•Adjust GAIN setting (according to procedure above) whenever road,
weather and trailer or vehicle loading conditions change from when
the GAIN was initially set.
•The manual control lever should only be used 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 TBC 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 TBC is equipped with a feature which 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 the vehicle’s brake pedal, not the TBC.
•The controller interacts with the brake control system and powertrain
control system of the 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 TBC
does not affect the operation of your vehicle’s brakes whether a
trailer is attached or not.
•When the vehicle is turned off, the TBC output is disabled and the
display and module are shut down. The TBC module and display turn
on when the ignition is turned from the off position to the on
position.
•The TBC is only a factory-installed or dealer-installed item. Ford is
not responsible for warranty or performance of the TBC due to
misuse or customer installation.
Trailer Lamps
Trailer lamps are required on most towed vehicles. Make sure all running
lights, brake lights, turn signals and hazard lights are working. Contact
your authorized dealer or trailer rental agency for proper instructions
and equipment for hooking up the lamps.
Before Towing a Trailer
Practice turning, stopping and backing up to get the feel of the
vehicle-trailer combination before starting on a trip. When turning, make
wider turns so the trailer wheels will 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
gearshift in positionPto 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, you may
experience AdvanceTrac™ with RSC activations during typical
cornering maneuvers with a heavily loaded trailer; this is normal.
Cornering at a slower speed while towing reduces the tendency of the
AdvanceTrac™ stability enhancement system to activate.
•If you are towing a trailer frequently in hot weather, hilly conditions,
at GCWR (or any combination of these factors), consider refilling
your rear axle with synthetic gear lubricant, if not already so
equipped. See theCapacities and Specificationschapter for the
lubricant specification.
•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 the vehicle tires away from
traffic flow.
2. Set the vehicle parking brake.
3. Place the automatic transmission in positionPor manual
transmission in a high gear.
4. Place wheel chocks in front and back of the trailer wheels.
(Chocks not equipped with vehicle.)
Your vehicle may be equipped with a temporary or conventional spare
tire. If the spare tire is different in size (diameter and/or width), tread
type (All-Season or All-Terrain) or is from a different manufacturer other
than the road tires on your vehicle, your spare tire is considered
“temporary”. 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 trailerbeforebacking the trailer into
the water.
Note:Reconnect the wiring to the trailer after the trailer is removed
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.

BREAKING-IN
You need to break in new tires for approximately 300 miles
(480 kilometers). During this time, your vehicle may exhibit some unique
driving characteristics. Avoid driving too fast during the first 1000 miles
(1600 kilometers). Vary your speed frequently and change up through
the gears early. Do not labor the engine. Do not tow during the first
1000 miles (1600 kilometers).
ECONOMICAL DRIVING
Fuel economy is affected by several things such as how you drive, the
conditions you drive under and how you maintain your vehicle.
There are some things to keep in mind that may improve your fuel
economy:
•Accelerate and slow down in a smooth, moderate fashion.
•Drive at steady speeds without stopping.
•Anticipate stops; slowing down may eliminate the need to stop.
•Combine errands and minimize stop-and-go driving.
•Close the windows for high-speed driving.
•Drive at reasonable speeds (traveling at 55 mph [88 km/h] uses 15%
less fuel than traveling at 65 mph [105 km/h]).
•Keep the tires properly inflated and use only the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduled maintenance.
There are also some things you may not want to do because they may
reduce your fuel economy:
•Sudden or hard accelerations.
•Rev the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on cold mornings.
•Use the air conditioner or front defroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal while driving.
•Drive a heavily loaded vehicle or tow a trailer.
264Driving Hints
2013 Expedition(exd)
Owners Guide gf, 1st Printing
USA(fus)

•Carry unnecessary weight (approximately 1 mpg [0.4 km/L] is lost for
every 400 lb [180 kg] of weight carried).
•Add particular accessories to your vehicle (e.g. bug deflectors,
rollbars/light bars, running boards, ski racks).
•Drive with the wheels out of alignment.
DRIVING THROUGH WATER
Note:Driving through deep water may allow water into the transmission
and engine causing internal damage. Have the fluid checked and, if water
is found, replace the fluid.
Do not drive quickly through standing water, especially if the depth is
unknown. Traction or brake capability may be limited and if the ignition
system gets wet, your engine may stall. Water may also enter your
engine’s air intake and severely damage your engine.
If driving through deep or standing
water is unavoidable, proceed very
slowly. Never drive through water
that is higher than the bottom of
the hubs (for trucks) or the bottom
of the wheel rims (for cars).
Once through the water, always try the brakes. Wet brakes do not stop
the vehicle as effectively as dry brakes. Drying can be improved by
moving your vehicle slowly while applying light pressure on the brake
pedal.
Driving Hints265

Should your vehicle shut off after a collision, you may restart your
vehicle by doing the following:
1. Turn the ignition off.
2. Turn the ignition on.
3. Repeat steps 1 and 2 to re-enable fuel pump.
Note:If your vehicle has the push button start system, press the
stop/start button twice to reactivate the fuel system.
JUMP-STARTING THE VEHICLE
WARNING:The gases around the battery can explode if exposed
to flames, sparks, or lit cigarettes. An explosion could result in
injury or vehicle damage.
WARNING:Batteries contain sulfuric acid which can burn skin,
eyes and clothing, if contacted.
Do not attempt to push-start your automatic transmission vehicle.
Automatic transmissions do not have push-start capability. Attempting to
push-start a vehicle with an automatic transmission may cause
transmission damage.
When the battery is disconnected or a new battery is installed, the
automatic transmission must relearn its shift strategy. As a result, the
transmission may exhibit a combination of firm and soft shifts. This
operation is considered normal and will not affect function or durability
of the transmission. Over time, the adaptive learning process will fully
update transmission operation.
Preparing Your Vehicle
Note:Use only a 12 volt supply to start your vehicle.
Note:Do not disconnect the battery of the disabled vehicle as this could
damage the vehicle’s electrical system.
1. Park the booster vehicle close to the hood of the disabled vehicle
making sure the two vehicles do not touch. Set the parking brake on
both vehicles and stay clear of the engine cooling fan and other moving
parts.
2. Check all battery terminals and remove any excessive corrosion before
you attach the battery cables. Ensure that vent caps are tight and level.
3. Turn the heater fan on in both vehicles to protect from any electrical
surges. Turn all other accessories off.
