LOAD CARRYING
PRECAUTIONS
Keep your loaded vehicle weightwithin its design rating capability,with or without a trailer. Properlyloading your vehicle providesmaximum return of vehicle designperformance. Before you load yourvehicle, become familiar with thefollowing terms for determiningyour vehicle’s weight rating, withor without a trailer, from thevehicle’s Tire and LoadingInformation label or SafetyCompliance Certification label.
WARNING: Vehicles witha higher center of gravity (utilityand four-wheel drive vehicles)handle differently than vehicleswith a lower center of gravity(passenger cars). Avoid sharpturns, excessive speed andabrupt steering in these vehicles.Failure to drive cautiouslyincreases the risk of losingcontrol of your vehicle, vehiclerollover, personal injury anddeath.
WARNING: Theappropriate loading capacity ofyour vehicle can be limited eitherby volume capacity (how muchspace is available) or by payloadcapacity (how much weight thevehicle should carry). Once youhave reached the maximum
payload of your vehicle, do notadd more cargo, even if there isspace available. Overloading orimproperly loading your vehiclecan contribute to loss of vehiclecontrol and vehicle rollover.
WARNING: Exceeding theSafety Compliance Certificationlabel vehicle weight limits canadversely affect theperformance and handling ofyour vehicle, cause vehicledamage and can result in theloss of control of your vehicle,serious personal injury or death.
WARNING: Do not usereplacement tires with lowerload carrying capacities than the
original tires because they maylower your vehicle's GVWR andGAWR limitations. Replacementtires with a higher limit than theoriginal tires do not increase theGVWR and GAWR limitations.
WARNING: Do not exceedthe GVWR or the GAWRspecified on the certificationlabel.
WARNING: Exceeding anyvehicle weight rating canadversely affect theperformance and handling ofyour vehicle, cause vehicledamage and can result in theloss of control of your vehicle,serious personal injury or death.

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 theleft-hand and right-hand sidetrailer 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 capacitywhen towing a conventionaltrailer, and should neverexceed 15% of the maximumtowing capacity when towinga fifth-wheel or goosenecktrailer.
•Select a ball mount with thecorrect rise or drop. When youconnect both the loadedvehicle and trailer, the trailerframe should be level, or
slightly angled down towardyour vehicle, when viewed fromthe side.
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.
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.
•If your vehicle has AdvanceTrac withroll stability control, this system mayturn on during typical corneringmaneuvers with a heavily loaded trailer.This is normal. Turning the corner at aslower speed when towing may reducethis tendency.
•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.

6.If the trailer wheels lock up, indicatedby squealing tires, reduce the gainsetting. If the trailer wheels turn freely,increase the gain setting. Repeat Steps5 and 6 until the gain setting is at apoint just below trailer wheel lock-up.If towing a heavier trailer, trailer wheellock-up may not be attainable evenwith the maximum gain setting of 10.
Note:Only perform this procedure atspeeds of approximately 20–25 mph(30–40 km/h).
Note:The trailer brake controller reducesoutput at vehicle speeds below 11 mph(18 km/h) so that trailer and vehicle brakingis not jerky or harsh. This feature is onlyavailable when applying the brakes usingyour vehicle's brake pedal, not thecontroller.
Note:Your vehicle's brake system and thetrailer brake system work independently ofeach other. Changing the gain setting on thecontroller does not affect the operation ofyour vehicle's brakes whether you attach atrailer or not.
Note:With the proper electrical connection,pressing your vehicle brake pedal or usingthe manual control lever illuminates bothtrailer and vehicle brake lamps.
Note:When you switch the engine off, thecontroller output is disabled and the displayand module shut down. The controllermodule and display turn on when you switchthe ignition on.
Note:Trailer braking is suspended duringstop/start events to minimize battery draw.
Adjusting the Trailer Brake Gain
Use the gain adjustment (+) and(-) buttons to increase ordecrease the gain setting to thedesired starting point. The trailerbrake controller allowsadjustment of brake gain from0% to 100% in 5% increments.
A
Trailer braking is directly appliedby the driver through this manualslider.
B
Note:Adjust gain setting before using thetrailer brake controller for the first time.
Note:The gain should be set to provide themaximum trailer braking assistance whilemaking sure the trailer wheels do not lockwhen using the brakes. Locked trailer wheelsmay lead to trailer instability.
Note:Setting adjustments are saved whena trailer profile is selected.
Note:If you have installed an aftermarkettrailer brake controller in addition to theintegrated trailer brake controller, set thegain on the integrated trailer brake controllerto zero.
