The gross combined weight mustnever exceed the Gross CombinedWeight Rating.
LOCATING THE SAFETY
COMPLIANCE CERTIFICATION
LABELS
Safety Compliance Certification LabelExample:
The Safety Compliance Certification labelis located on the door hinge pillar,door-latch post, or the door edge thatmeets the door-latch post, next to thedriver seating position.
WHAT IS THE GROSS AXLE
WEIGHT RATING
GAWR (Gross Axle WeightRating)
GAWR is the maximum allowableweight that a single axle (front orrear) can carry. These numbersare on the Safety ComplianceCertification label.
WHAT IS THE GROSS VEHICLE
WEIGHT RATING
GVWR is the maximum allowableweight of the fully loaded vehicle.This includes all options,equipment, passengers and cargo.It appears on the SafetyCompliance Certification label.
WHAT IS THE GROSS
COMBINED WEIGHT RATING
Gross Combined Weight Rating(GCWR) 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 ratedfor operation at Gross VehicleWeight Rating, not at GrossCombined Weight Rating.)Separate functional brakes shouldbe used for safe control of towedvehicles and for trailers where the

CALCULATING PAYLOAD
Tire and Loading Label InformationExample:
Payload is the combined weightof cargo and passengers that yourvehicle is carrying. The maximumpayload for your vehicle appearson the Tire and Loading label. Thelabel is either on the B-pillar or theedge of the driver door. Vehicles
exported outside the US andCanada may not have a tire andloading label. Look for “Thecombined weight of occupantsand cargo should never exceedXXX kg or XXX lb” for maximumpayload. The payload listed on theTire and Loading Information labelis the maximum payload for yourvehicle as built by the assemblyplant. If you install any additionalequipment on your vehicle, youmust determine the new payload.Subtract the weight of theequipment from the payload listedon the Tire and Loading label.When towing, trailer tongueweight or king pin weight is alsopart of payload.
CALCULATING THE LOAD
LIMIT
Steps for determining the correctload limit:
1.Locate the statement "Thecombined weight of occupantsand cargo should never exceedXXX kg or XXX lb." on yourvehicle’s placard.
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.
Helpful examples forcalculating the availableamount of cargo and luggageload 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 capacityto carry that much weight. Inmetric units, the calculation wouldbe: 635 kilograms - (2 x 99kilograms) - (12 x 45 kilograms) =635 - 198 - 540 = -103 kilograms.You will need to reduce the loadweight by at least 240 pounds(104 kilograms). If you removethree 100-pound (45-kilogram)cement bags, then the loadcalculation would be: 1400 - (2 x220) - (9 x 100) = 1400 - 440 -
900 = 60 pounds. Now you have

CONNECTING A TRAILER
PRECAUTIONS
Do not tow a trailer until you drive yourvehicle at least 1,000 mi (1,600 km).
Consult your local motor vehicle laws fortowing a trailer.
See the instructions included with towingaccessories for the proper installation andadjustment specifications.
Service your vehicle more frequently if youtow a trailer. See Normal ScheduledMaintenance (page 542).
If you use a rental trailer, follow theinstructions the rental agency gives you.
When attaching the trailer wiring connectorto your vehicle, only use a proper fittingconnector that works with the vehicle andtrailer functions.
Account for the trailer coupler weight aspart of your vehicle load when calculatingthe total vehicle weight.
Do not exceed the load limits. SeeCalculating the Load Limit (page 347).
HITCHES
INSTALLING A HITCH
WARNING: Do not cut, drill, weldor modify the trailer hitch. Modifying thetrailer hitch could reduce the hitch rating.
Do not use a hitch that either clamps ontothe bumper or attaches to the axle. Youmust distribute the load in your trailer sothat 10-15% of the total weight of thetrailer is on the tongue. Do not exceed thetongue load rating indicated on the hitchreceiver.
Trailer Hitch Cover
Your vehicle has a removable trailer hitchcover. To remove the trailer hitch cover:
1.Grab the trailer hitch cover at thebottom and pull towards the rear ofthe vehicle until the bottom of thetrailer hitch cover unsnaps from thebumper.
2.Grab the trailer hitch cover at the edgeand rotate until the top of the trailerhitch cover unsnaps from the bumper,then remove the trailer hitch cover.
To install the trailer hitch cover:
1.Line up the snaps on the trailer hitchcover to the holes on the bumper andpush forward until it snaps into place.

Certain states require functioning trailerbrakes for trailers over a specified weight.Be sure to check state regulations for thisspecified weight.
Ford Motor Company recommendsseparate functioning brake systems fortrailers weighing more than 1,500 lb(680 kg) when loaded.
TOWING A TRAILER
LIMITATIONS
The vehicle's load capacitydesignation is by weight, not byvolume, so you cannot necessarilyuse all available space whenloading a vehicle or trailer.
Note:Your vehicle could havereduced performance whenoperating at high altitudes andwhen heavily loaded or towing a
trailer. When driving at elevation,to match driving performance asperceived at sea level, reduce grossvehicle weight and grosscombination weight by 2% per1,000 ft (300 m) elevation.
LOADING YOUR TRAILER
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. Thetrailer tongue weight shouldnever exceed 10% of themaximum towing capacity.
•Select a ball mount 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.
TRAILER TOWING HINTS
Towing a trailer places an extra load onyour vehicle's engine, transmission, axle,brakes, tires and suspension. Periodicallyinspect these components during and afterany towing operation.
When driving with a trailer or payload, aslight takeoff vibration or shudder may bepresent due to the increased payloadweight.
Your vehicle may have a temporary orconventional spare tire. A temporary sparetire is different in diameter or width,tread-type, or is from a differentmanufacturer than the road tires on yourvehicle. Consult information on the tirelabel or Safety Compliance label forlimitations when using.

2023 Expedition (TB8) Canada/United States of America, enUSA, Edition date: 202207, DOMTowing a Trailer

When towing a trailer:
•Obey country specific regulations fortowing a trailer.
•Do not drive faster than 70 mph(113 km/h) during the first 500 mi(800 km).
•Do not make full-throttle starts.
•Check your hitch, electrical connectionsand trailer wheel lug nuts thoroughlyafter you have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engineand transmission cooling and to helpA/C performance.
•Turn off the speed control with heavyloads or in hilly terrain. The speedcontrol may turn off when you aretowing on long, steep slopes.
•Shift to a lower gear when driving downa long or steep hill. Do not continuouslyapply the brakes, as they may overheatand become less effective.
•If your transmission has Grade Assistor Tow/Haul, use this feature whentowing. This provides engine brakingand helps eliminate excessivetransmission shifting for optimum fueleconomy and transmission cooling.
•Your vehicle has AdvanceTrac with rollstability control. When towing a trailer,additional loads could cause theAdvanceTrac system to engage duringcornering maneuvers. Reduce corneringspeeds to make sure that you canmaintain control of the vehicle andtrailer if the AdvanceTrac systemengages.
•Allow more distance for stopping witha trailer attached. Anticipate stops andgradually brake.
•Avoid parking on a slope. However, ifyou must park on a slope, turn thesteering wheel to point your vehicletires away from traffic flow, set theparking brake, place the transmissionin park (P) and place wheel chocks infront and back of the trailer wheels.
Note:Chocks are not included with yourvehicle.
LAUNCHING OR RETRIEVING
A BOAT OR PERSONAL
WATERCRAFT
When backing down a ramp during boatlaunching or retrieval:
•Do not allow the static water level torise above the bottom edge of the rearbumper.
•Do not allow waves to break higherthan 6 in (15 cm) above the bottomedge of the rear bumper.
Exceeding 6 in (15 cm) could allow waterto enter vehicle components, causinginternal damage to the components andaffecting driveability, emissions andreliability.
Note:Replace the rear axle lubricantanytime the rear axle has been submergedin water.
Note:Disconnect the trailer wiringconnector before backing the trailer into thewater.
Note:Reconnect the trailer wiringconnector after removing the trailer fromthe water.
