for operation at Gross VehicleWeight Rating, not at GrossCombined Weight Rating.)Separate functional brakes shouldbe used for safe control of towedvehicles and for trailers where theGross Combined Weight of thetowing vehicle plus the trailerexceed the Gross Vehicle WeightRating of the towing vehicle.TheGross Combined Weight mustnever exceed the GrossCombined Weight Rating.
Maximum Loaded TrailerWeight - is the highest possibleweight of a fully loaded trailer thevehicle can tow. It assumes avehicle with mandatory options,driver and front passenger weight(150 pounds [68 kilograms]each), no cargo weight (internalor external) and a tongue load of10–15% (conventional trailer) orking pin weight of 15–25% (fifthwheel trailer). Consult anauthorized dealer (or the RV andTrailer Towing Guide available atan authorized dealer) for moredetailed information.
Tongue Load or Fifth WheelKing Pin Weight - refers to theamount of the weight that a trailerpushes down on a trailer hitch.
Examples: For a 5000 pound(2268 kilogram) conventionaltrailer, multiply 5000 by 0.10 and0.15 to obtain a proper tongueload range of 500 to 750 pounds(227 to 340 kilograms). For an11500 pound (5216 kilogram) fifthwheel trailer, multiply by 0.15 and0.25 to obtain a proper king pinload range of 1725 to 2875 pounds(782 to 1304 kilograms).
WARNINGS
Do not exceed the GVWR orthe GAWR specified on theSafety Compliance CertificationLabel.
Do not use replacement tireswith lower load carryingcapacities than the original tiresbecause they may lower thevehicle’s GVWR and GAWRlimitations. Replacement tireswith a higher limit than the originaltires do not increase the GVWRand GAWR limitations.
Exceeding any vehicle weightrating limitation could resultin serious damage to the vehicleand/or personal injury.
Steps for determining thecorrect load limit:
1.Locate the statement "Thecombined weight of occupantsand cargo should never exceedXXX kg or XXX lb." on yourvehicle’s placard.

TOWING A TRAILER
WARNINGS
Do not exceed the GVWR orthe GAWR specified on thecertification label.
Towing trailers beyond themaximum recommendedgross trailer weight exceeds thelimit of the vehicle and couldresult in engine damage,transmission damage, structuraldamage, loss of vehicle control,vehicle rollover and personalinjury.
Your vehicle may have electricalitems, such as fuses or relays,related to towing. See the Fuseschapter.
Your vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle.
Towing a trailer places an extraload on your vehicle's engine,transmission, axle, brakes, tiresand suspension. Inspect thesecomponents periodically during,and after, any towing operation.
Load Placement
To help minimize how trailermovement affects your vehiclewhen driving:
•Load the heaviest items closestto the trailer floor.
•Load the heaviest itemscentered between the left andright side trailer tires.
•Load the heaviest items abovethe trailer axles or just slightlyforward toward the trailertongue. Do not allow the finaltrailer tongue weight to goabove or below 10-15% of theloaded trailer weight.
•Select a tow bar with thecorrect rise or drop. When boththe loaded vehicle and trailerare connected, the trailer frameshould be level, or slightlyangled down toward yourvehicle, when viewed from theside.
When driving with a trailer orpayload, a slight takeoff vibrationor shudder may be present due tothe increased payload weight.Additional information regardingproper trailer loading and settingyour vehicle up for towing islocated in another chapter of thismanual. See Load Limit (page178). You can also find theinformation in the RV & TrailerTowing Guide, available at anauthorized dealer.

TRAILER SWAY CONTROL (IF
EQUIPPED)
WARNING
Turning off trailer sway controlincreases the risk of loss of vehiclecontrol, serious injury or death. Forddoes not recommend disabling this featureexcept in situations where speed reductionmay be detrimental (such as hill climbing),the driver has significant trailer towingexperience, and can control trailer swayand maintain safe operation.
Note:This feature does not prevent trailersway, but reduces it once it begins.
Note:This feature cannot stop all trailersfrom swaying.
Note:In some cases, if vehicle speed is toohigh, the system may activate multipletimes, gradually reducing vehicle speed.
This feature applies your vehicle brakes atindividual wheels and, if necessary, reducesengine power. If the trailer begins to sway,the stability control light flashes and themessage TRAILER SWAY REDUCESPEED appears in the information display.The first thing to do is slow your vehicledown, then pull safely to the side of theroad and check for proper tongue load andtrailer load distribution. See LoadCarrying (page 178).
RECOMMENDED TOWING
WEIGHTS
Note:Do not exceed a trailerweight of 5000 pounds (2268kilograms) when towing with, orby, bumper only.
Note:Make sure to take intoconsideration trailer frontal area.Do not exceed 60 feet2 (5.6
meters2) trailer frontal area.
Note:Exceeding this limitationmay significantly reduce theperformance of your towingvehicle. Selecting a trailer with alow aerodynamic drag and roundedfront design helps optimizeperformance and fuel economy.
Note:For high altitude operation,reduce the gross combined weightby 2% per 1000 feet (300 meters)starting at the 1000 foot (300meter) elevation point.
Note:Certain states requireelectric trailer brakes for trailersover a specified weight. Be sure tocheck state regulations for thisspecified weight. The maximumtrailer weights listed may be limitedto this specified weight, as yourvehicle's electrical system may notinclude the wiring connectorneeded to use electric trailerbrakes.
Your vehicle may tow a class I, II,III and IV trailer or fifth-wheeltrailer provided the maximumtrailer weight is less than or equalto the maximum trailer weightlisted for your vehicleconfiguration on the followingchart.

•Service your vehicle morefrequently if you tow a trailer.See your scheduledmaintenance information.
•If you use a rental trailer, followthe instructions the rentalagency gives you.
See Load limits in the LoadCarrying chapter for loadspecification terms found on thetire label and Safety Compliancelabel and instructions oncalculating your vehicle's load.
Remember to account for thetrailer tongue weight as part ofyour vehicle load when calculatingthe total vehicle weight.
Trailer Towing Connector
When attaching the trailer wiringconnector to your vehicle, only usea proper fitting connector thatworks with the vehicle and trailerfunctions. Some seven-positionconnectors may have the SAEJ2863 logo, which confirms that itis the proper wiring connector andworks correctly with your vehicle.

Trailer Brakes
WARNING
Do not connect a trailer'shydraulic brake systemdirectly to your vehicle's brakesystem. Your vehicle may not haveenough braking power and yourchances of having a collisiongreatly increase.
Electric brakes and manual,automatic or surge-type trailerbrakes are safe if you install themproperly and adjust them to themanufacturer's specifications. Thetrailer brakes must meet local andfederal regulations.
The rating for the tow vehicle'sbraking system operation is atthe gross vehicle weight rating,not the gross combined weightrating.
Separate functioning brakesystems are required for safecontrol of towed vehicles andtrailers weighing more than1500 pounds (680 kilograms)when loaded.
Integrated Trailer BrakeController (If Equipped)
WARNING
The Ford trailer brakecontroller has been verifiedto be compatible with trailershaving electric-actuated drumbrakes (one to four axles) andsome electric-over-hydraulicbrakes. It will not activatehydraulic surge-style trailerbrakes. It is the responsibility ofthe customer to ensure that thetrailer brakes are adjustedappropriately, functioningnormally and all electricconnections are properly made.Failure to do so may result in lossof vehicle control, crash or serious
injury.
When used properly, the trailerbrake controller assists in smoothand effective trailer braking bypowering the trailer’s electric orelectric-over-hydraulic brakeswith a proportional output basedon the towing vehicle’s brakepressure.
198Super Duty (), enUSATowingBAE163166

You can adjust the amount ofinitial trailer brake output byselecting one of three settingsthrough the message center.
Ford has tested the trailer brakecontroller to be compatible withseveral major brands ofelectric-over-hydraulic trailerbrakes. Contact an authorizeddealer for information on whichbrands you can use.
The controller user interfaceconsists of the following:
A: + and - (Gain adjustmentbuttons): Pressing these buttonsadjusts the controller's poweroutput to the trailer brakes in 0.5increments. You can increase thegain setting to 10.0 (maximumtrailer braking) or decrease it to 0(no trailer braking). Pressing andholding a button raises or lowersthe setting continuously. The gainsetting displays in the messagecenter as follows: TBC GAIN =XX.X.
B: Manual control lever: Slide thecontrol lever to the left to switchon the trailer's electric brakesindependent of the tow vehicle's.See the following Procedure foradjusting gain section forinstructions on proper use of thisfeature. If you use the manualcontrol while the brake is alsoapplied, the greater of the twoinputs determines the power sentto the trailer brakes.
•Stop lamps: Using the manualcontrol lever lights both thetrailer brake lamps and yourvehicle brake lamps except thecenter high-mount stop lamp,if you make the properelectrical connection to thetrailer. Pressing your vehiclebrake pedal also lights bothtrailer and vehicle brake lamps.
The controller shows gain setting,output bar graph, and trailerconnectivity status in theinformation display. They appearin the information display asfollows:
•TBC GAIN = XX.X NOTRAILER: Shows the currentgain setting during a givenignition cycle and when
adjusting the gain. This alsodisplays if you use the manualcontrol lever or make gainadjustments with no trailerconnected.
•TBC GAIN = XX.XOUTPUT=/ / / / / /: Displayswhen you push your vehicle'sbrake pedal, or upon use of themanual control. Bar indicatorslight in the information displayto indicate the amount ofpower going to the trailerbrakes relative to the brakepedal or manual control input.One bar indicates the leastamount of output; six barsindicate maximum output.

•TRAILER CONNECTED:Displays when the systemsenses a correct trailer wiringconnection during a givenignition cycle.
•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
