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.

Calculating the MaximumLoaded Trailer Weight for YourVehicle
1. Start with the gross combinedweight rating for your vehiclemodel and axle ratio. See theprevious chart.
2.Subtract all of the followingthat apply to your vehicle:
•Vehicle curb weight
•Hitch hardware weight, such asa draw bar, ball, locks or weightdistributing hardware
•Driver weight
•Passenger(s) weight
•Payload, cargo and luggageweight
•Aftermarket equipment weight.
This equals the maximum loadedtrailer weight for this combination.
Note:The trailer tongue load isconsidered part of the payload foryour vehicle. Reduce the totalpayload by the final trailer tongueweight.
Note:Consult an authorized dealerto determine the maximum trailer
weight allowed for your vehicle ifyou are not sure.
ESSENTIAL TOWING CHECKS
Follow these guidelines for safetowing:
•Do not tow a trailer until youdrive your vehicle at least 1000miles (1600 kilometers).
•Consult your local motorvehicle laws for towing a trailer.
•See the instructions includedwith towing accessories for theproper installation andadjustment specifications.

Towing

•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.

Hitches
WARNING
On pick-up trucks, the trailerhitch provided on this vehicleenhances crash protection for thefuel system. Do not remove!

Do not use a hitch that eitherclamps onto the bumper orattaches to the axle. You mustdistribute the load in your trailerso that 10-15% for conventionaltowing or 15-25% for fifth wheeltowing of the total weight of thetrailer is on the tongue.
Weight-distributing Hitches
WARNING
Do not adjust aweight-distributing hitch toany position where the rearbumper of the vehicle is higherthan it was before attaching thetrailer. Doing so will defeat thefunction of the weight-distributinghitch, which may causeunpredictable handling, and could
result in serious personal injury.
When hooking-up a trailer using aweight-distributing hitch, alwaysuse the following procedure:
1. Park the loaded vehicle,without the trailer, on a levelsurface.
2.Measure the height to the topof your vehicle's front wheelopening on the fender. This isH1.
3.Attach the loaded trailer toyour vehicle without theweight-distributing barsconnected.
4.Measure the height to the topof your vehicle's front wheelopening on the fender a secondtime. This is H2.
5.Install and adjust the tensionin the weight-distributing barsso that the height of yourvehicle's front wheel openingon the fender is approximatelyhalfway between H1 and H2.
6.Check that the trailer is level orslightly nose down toward yourvehicle. If not, adjust the ballheight accordingly and repeatSteps 2-6.
Once the trailer is level or slightlynose down toward the vehicle:
•Lock the bar tension adjusterin place.
•Check that the trailer tonguesecurely attaches and locksonto the hitch.
•Install safety chains, lighting,and trailer brake controls asrequired by law or the trailermanufacturer.
Fifth-wheel Trailer Hitch (IfEquipped)
WARNINGS
The mounting pads in the bedare specifically designed forcertain fifth-wheel trailer hitchesand gooseneck ball hitches. Donot use these mounting pads forother purposes. Doing so couldresult in vehicle structural

WARNINGS
damage, loss of vehicle control,and personal injury. Contact anauthorized dealer to purchasegooseneck and fifth-wheel hitchesthat are compatible with yourvehicle.
Towing trailers beyond themaximum limit of the towingsystem could result in vehiclestructural damage, loss of vehiclecontrol and personal injury.
The hitch rating listed on thetrailer hitch label is themaximum possible trailer rating.To find the maximum trailerweight allowed for your specificvehicle, consult an authorizeddealer or the RV & Trailer TowingGuide provided by an authorizeddealer.
Your vehicle may be equippedwith a fifth-wheel prep package.This package enables your vehicleto accept certain fifth-wheeltrailer hitches and gooseneck ballhitches. The fifth-wheel trailerhitch attaches to the fourmounting pads in the pick-up bed.An optional 7-pin trailer wiringconnector may be in the bed aswell. The gooseneck ball hitch isa separate mounting pad from thefifth-wheel hitch, located in thecenter of the bed.
Shorter pick-up boxes, such as the6½-foot box on the F-250 andF-350, provide less clearancebetween the cab and thefifth-wheel and gooseneck trailercompared to longer box pick-ups,such as an 8-foot box on theF-250 or F-350. When selecting atrailer and tow vehicle, it is criticalto check that this combinationprovides clearance between thefront of the trailer and tow vehiclefor turns up to 90 degrees. Failureto follow this recommendationcould result in the trailercontacting the cab of the towvehicle during tight turns that aretypical during low-speed parkingand turning maneuvers. Thiscontact could result in damage tothe trailer and tow vehicle.
Safety Chains
Note:Do not attach safety chainsto the bumper.
Always connect the safety chainsto the frame or hook retainers ofyour vehicle hitch.
To connect the safety chains,cross the chains under the trailertongue and allow enough slack forturning tight corners. Do not allowthe chains to drag on the ground.
