•TRAILER DISCONNECTED:Displays, accompanied by asingle audible time, when thesystem senses a trailerconnection and then adisconnection, eitherintentional or unintentional,during a given ignition cycle. Italso displays if a truck ortrailer-wiring fault occurscausing the trailer to appeardisconnected. This messagecan also display if you use themanual control lever without atrailer connected.
Procedure for Adjusting Gain
Note:Only perform this procedurein a traffic-free environment atspeeds of approximately 20-25mph (30-40 km/h).
The gain setting sets the trailerbrake controller for the specifictowing condition. You shouldchange the setting as towingconditions change. Changes totowing conditions include trailerload, vehicle load, road conditionsand weather.
The gain should be set to providethe maximum trailer brakingassistance while making sure thetrailer wheels do not lock whenusing the brakes. Locked trailerwheels may lead to trailerinstability.
1.Make sure the trailer brakes arein good working condition,functioning normally andproperly adjusted. See yourtrailer dealer if necessary.
2.Hook up the trailer and makethe electrical connectionsaccording to the trailermanufacturer's instructions.
3.When you plug in a trailer withelectric orelectric-over-hydraulic brakes,TRAILER CONNECTEDappears in the informationdisplay.
4.Use the gain adjustment (+ and-) buttons to increase ordecrease the gain setting to thedesired starting point. A gainsetting of 6.0 is a good startingpoint for heavier loads.
5.In a traffic-free environment,tow the trailer on a dry, levelsurface at a speed of 20-25mph (30-40 km/h) andsqueeze the manual controllever completely.
6.If the trailer wheels lock up,indicated by squealing tires,reduce the gain setting. If thetrailer wheels turn freely,
increase the gain setting.Repeat Steps 5 and 6 until the

gain setting is at a point justbelow trailer wheel lock-up. Iftowing a heavier trailer, trailerwheel lock-up may not beattainable even with themaximum gain setting of 10.
Initial Output Setting
The trailer brake controller letsyou customize how aggressivelythe trailer brakes engage. Thedefault value is set to “Light”. Werecommend this setting for themajority of trailers. If you are usingan EOH trailer with a high settingvoltage, or if you prefer to feelmore brake feedback from thetrailer, then select “Medium” or“Heavy”.
Trailer Brake Effort Setting
The trailer brake controller allowsthe user to customize howaggressively the trailer brakesengage. The default value is "Low"and is the recommended settingfor most trailers. If your trailer'sbrakes require more initial voltage,or if you prefer more aggressivetrailer braking, then select eitherthe "Medium" or the "High"setting.
Information Display WarningMessages
Note:An authorized dealer candiagnose the trailer brake controllerto determine exactly which trailerfault has occurred. However, yourFord warranty does not cover thisdiagnosis if the fault is with thetrailer.

If the message only displays witha trailer connected, the problemis with the trailer wiring. Consultyour trailer dealer for assistance.This can be a short to ground(such as a chaffed wire), short tovoltage (such as a pulled pin ontrailer emergency breakawaybattery) or the trailer brakes maybe drawing too much current.
Points to Remember
Note:Do not attempt removal ofthe trailer brake controller withoutconsulting the Workshop Manual.Damage to the unit may result.
•Adjust gain setting before usingthe trailer brake controller forthe first time.
•Adjust gain setting, using theprocedure above, wheneverroad, weather and trailer orvehicle loading conditionschange from when the gainwas initially set.
•Only use the manual controllever for proper adjustment ofthe gain during trailer setup.Misuse, such as applicationduring trailer sway, could causeinstability of trailer or towvehicle.
•Avoid towing in adverseweather conditions. The trailerbrake controller does notprovide anti-lock control of thetrailer wheels. Trailer wheelscan lock up on slipperysurfaces, resulting in reducedstability of trailer and towvehicle.
•The trailer brake controller isequipped with a feature thatreduces output at vehiclespeeds below 11 mph (18 km/h)so trailer and vehicle braking isnot jerky or harsh. This featureis only available when applyingthe brakes using your vehicle'sbrake pedal, not the controller.
•The controller interacts withthe brake control system andpowertrain control system ofyour vehicle to provide the bestperformance on different roadconditions.
•Your vehicle's brake systemand the trailer brake systemwork independently of eachother. Changing the gainsetting on the controller doesnot affect the operation of yourvehicle's brakes whether youattach a trailer or not.

•When you switch the engineoff, the controller output isdisabled and the display andmodule shut down. Thecontroller module and displayturn on when you switch theignition on.
•The trailer brake controller isonly a factory-installed ordealer-installed item. Ford isnot responsible for warranty orperformance of the controllerdue to misuse or customerinstallation.
Trailer Lamps
WARNING
Never connect any trailerlamp wiring to the vehicle'stail lamp wiring; this may damagethe electrical system resulting infire. Contact your authorizeddealer as soon as possible forassistance in proper trailer towwiring installation. Additionalelectrical equipment may berequired.
Trailer lamps are required on mosttowed vehicles. Make sure allrunning lights, brake lights, turnsignals and hazard lights areworking.
Using a Step Bumper (IfEquipped)
The rear bumper is equipped withan integral hitch and only requiresa ball with a one-inch (25.4millimeter) shank diameter. Thebumper has a 5000-pound (2268kilogram) trailer weight and a500-pound (227 kilogram) tongueweight capacity
If it is necessary to relocate thehitch ball position, you must installa frame-mounted trailer hitch.
Before Towing a Trailer
Practice turning, stopping andbacking up to get the feel of yourvehicle-trailer combination beforestarting on a trip. When turning,
make wider turns so the trailerwheels clear curbs and otherobstacles.
When Towing a Trailer
•Do not drive faster than 70mph (113 km/h) during the first500 miles (800 kilometers).
•Do not make full-throttlestarts.
•Check your hitch, electricalconnections and trailer wheel
lug nuts thoroughly after youhave traveled 50 miles (80kilometers).

•When stopped in congested orheavy traffic during hotweather, place the gearshift inposition P to aid engine andtransmission cooling and tohelp A/C performance.
•Turn off the speed control withheavy loads or in hilly terrain.The speed control may turn offautomatically when you aretowing on long, steep grades.
•Shift to a lower gear whendriving down a long or steephill. Do not apply the brakescontinuously, as they mayoverheat and become lesseffective.
•If your transmission is equippedwith a Grade Assist orTow/Haul feature, use thisfeature when towing. Thisprovides engine braking andhelps eliminate excessivetransmission shifting foroptimum fuel economy andtransmission cooling.
•If your vehicle is equipped withAdvanceTrac with RSC, thissystem may turn on duringtypical cornering maneuverswith a heavily loaded trailer.This is normal. Turning thecorner at a slower speed whiletowing may reduce thistendency.
•If you are towing a trailerfrequently in hot weather, hillyconditions, at the grosscombined weight rating (or anycombination of these factors),consider refilling your rear axlewith synthetic gear lubricant (ifthe axle is not already filledwith it). See Capacities andSpecifications (page 301).
•Allow more distance forstopping with a trailerattached. Anticipate stops andbrake gradually.
•Avoid parking on a grade.However, if you must park on agrade:
1. Turn the steering wheel topoint your vehicle tires awayfrom traffic flow.
2.Set your vehicle parking brake.
3.Place the automatictransmission in position P.
4.Place wheel chocks in frontand back of the trailer wheels.(Chocks not included withvehicle.)
Your vehicle may be equippedwith a temporary or conventionalspare tire. A "temporary" spare tireis different in size (diameter orwidth), tread-type (All-Season orAll Terrain) or is from a differentmanufacturer than the road tireson your vehicle. Consultinformation on the tire label orSafety Compliance label forlimitations when using.

•Use a damper device such as a tarp,heavy blanket or piece of carpetdraped over the recovery strap to helpabsorb the energy in the event thestrap breaks.
•Make sure the stuck vehicle is notloaded heavier than its gross vehicleweight rating specified on thecertification label.
•Always align the tow vehicle and stuckvehicle in a straight line (within 10degrees).
•Keep bystanders to the sides of thevehicle, at a distance of at least twicethe length of the recovery strap. Thishelps avoid injury from the hazard of arecovery hook or strap breaking, or avehicle lurching into their path.
TRANSPORTING THE VEHICLE
If you need to have your vehicle towed,contact a professional towing service or,if you are a member of a roadsideassistance program, your roadsideassistance service provider.

BREAKING-IN
You need to break in new tires forapproximately 300 miles (480kilometers). During this time, your vehiclemay exhibit some unusual drivingcharacteristics.
Avoid driving too fast during the first 1000miles (1600 kilometers). Vary your speedfrequently and change up through thegears early. Do not labor the engine.
Do not tow during the first 1000 miles(1600 kilometers).
ECONOMICAL DRIVING
Your fuel economy is affected by severalthings, such as how you drive, theconditions you drive under, and how youmaintain your vehicle.
You may improve your fuel economy bykeeping these things in mind:
•Accelerate and slow down in a smooth,moderate fashion.
•Drive at steady speeds withoutstopping.
•Anticipate stops; slowing down mayeliminate the need to stop.
•Combine errands and minimizestop-and-go driving.
•Close the windows for high-speeddriving.
•Drive at reasonable speeds (travelingat 55 mph [88 km/h] uses 15% lessfuel than traveling at 65 mph [105km/h]).
•Keep the tires properly inflated and useonly the recommended size.
•Use the recommended engine oil.
•Perform all regularly scheduledmaintenance.
Avoid these actions; they reduce your fueleconomy:
•Sudden accelerations or hardaccelerations.
•Revving the engine before turning it off.
•Idle for periods longer than one minute.
•Warm up your vehicle on coldmornings.
•Use the air conditioner or frontdefroster.
•Use the speed control in hilly terrain.
•Rest your foot on the brake pedal whiledriving.
•Drive a heavily loaded vehicle or tow atrailer.
•Carry unnecessary weight(approximately 1 mpg [0.4 km/L] islost for every 400 lb [180 kilogram] ofweight carried).
•Driving with the wheels out ofalignment.
Conditions
•Heavily loading a vehicle or towing atrailer may reduce fuel economy at anyspeed.
•Adding certain accessories to yourvehicle (for example bug deflectors,rollbars, light bars, running boards, skiracks or luggage racks) may reducefuel economy.
•To maximize the fuel economy, drivewith the tonneau cover installed (ifequipped).
•Using fuel blended with alcohol maylower fuel economy.
•Fuel economy may decrease with lowertemperatures during the first 8–10miles (12–16 kilometers) of driving.
•Driving on flat terrain offers improvedfuel economy as compared to drivingon hilly terrain.
