WARNING
Exceeding the SafetyCompliance CertificationLabel vehicle weight rating limitscould result in substandardvehicle handling or performance,engine, transmission and/orstructural damage, seriousdamage to the vehicle, loss ofcontrol and personal injury.
GCW (Gross Combined Weight)- is the Gross Vehicle Weight plusthe weight of the fully loadedtrailer.
GCWR (Gross CombinedWeight Rating) - is the maximumallowable weight of the vehicleand the loaded trailer, includingall cargo and passengers, that thevehicle can handle without riskingdamage. (Important: The towingvehicle’s braking system is rated

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.
183Super Duty (), enUSALoad Carrying

2.Determine the combinedweight of the driver andpassengers that will be ridingin your vehicle.
3.Subtract the combined weightof the driver and passengersfrom XXX kg or XXX lb.
4.The resulting figure equals theavailable amount of cargo andluggage load capacity. Forexample, if the “XXX” amountequals 1,400 lb. and there willbe five 150 lb. passengers inyour vehicle, the amount ofavailable cargo and luggageload capacity is 650 lb.(1400-750 (5 x 150) = 650 lb.)
5.Determine the combinedweight of luggage and cargobeing loaded on the vehicle.That weight may not safelyexceed the available cargo andluggage load capacitycalculated in Step 4.
6.If your vehicle will be towing atrailer, load from your trailerwill be transferred to yourvehicle. Consult this manual todetermine how this reduces theavailable cargo and luggageload capacity of your vehicle.
The following gives you a fewexamples on how to calculate theavailable amount of cargo andluggage load capacity:
*Suppose your vehicle has a1400-pound (635-kilogram) cargoand luggage capacity. You decideto go golfing. Is there enough loadcapacity to carry you, four of yourfriends and all the golf bags? Youand four friends average 220pounds (99 kilograms) each andthe golf bags weigh approximately30 pounds (13.5 kilograms) each.The calculation would be: 1400 -(5 x 220) - (5 x 30) = 1400 - 1100- 150 = 150 pounds. Yes, you haveenough load capacity in yourvehicle to transport four friendsand your golf bags. In metric units,the calculation would be: 635kilograms - (5 x 99 kilograms) -(5 x 13.5 kilograms) = 635 - 495 -67.5 = 72.5 kilograms.
*Suppose your vehicle has a1400-pound (635-kilogram) cargoand luggage capacity. You andone of your friends decide to pickup cement from the local homeimprovement store to finish thatpatio you have been planning forthe past two years. Measuring theinside of the vehicle with the rearseat folded down, you have roomfor twelve 100-pound(45-kilogram) bags of cement. Doyou have enough load capacity totransport the cement to yourhome? If you and your friend eachweigh 220 pounds (99 kilograms),the calculation would be: 1400 -(2 x 220) - (12 x 100) = 1400 - 440- 1200 = - 240 pounds. No, you donot have enough cargo capacity
to carry that much weight. Inmetric units, the calculation would

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.
