2015 FORD EXPEDITION brake

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

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.

•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 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 your vehicle tires away from
traffic flow.
2. Set your vehicle parking brake.
3. Place the automatic transmission in positionP.
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 trailerbeforebacking the trailer into
the water.
Note:Reconnect the wiring to the trailerafterremoving 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 submerges in
water. Water may have contaminated the rear axle lubricant, which does
not normally require checking or changing unless it is leaking or other
axle repair is required.

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.
•Carry unnecessary weight (approximately 1 mpg [0.4 km/L] is lost for
every 400 pounds [180 kilograms] of weight carried).
