TOWING A TRAILER
PRECAUTIONS
WARNING: Do not exceedthe GVWR or the GAWRspecified on the certificationlabel.
WARNING: Towing trailersbeyond the maximumrecommended gross trailerweight exceeds the limit of yourvehicle and could result in enginedamage, transmission damage,structural damage, loss ofvehicle control, vehicle rolloverand personal injury.
WARNING: Do not exceedthe lowest rating capacity foryour vehicle or trailer hitch.Overloading your vehicle ortrailer hitch can impair yourvehicle stability and handling.Failure to follow this instructioncould result in the loss of controlof your vehicle, personal injury ordeath.
WARNING: Make sure thatthe vertical load on the tow ballis between the minimum andmaximum recommended weightat all times. Failure to follow thisinstruction could result in theloss of control of your vehicle,personal injury or death.
WARNING: Do not cut,drill, weld or modify the trailerhitch. Modifying the trailer hitchcould reduce the hitch rating.
WARNING: The anti-lockbrake system does not controlthe trailer brakes.
TRAILER BRAKE
PRECAUTIONS
WARNING: Do not connect atrailer's hydraulic brake system directlyto your vehicle's brake system. Yourvehicle may not have enough brakingpower and your chances of having acollision greatly increase.
WARNING: Do not tow a trailerfitted with electric trailer brakes unlessyour vehicle is fitted with a compatibleaftermarket electronic trailer brakecontroller. Failure to follow thisinstruction could result in the loss ofcontrol of your vehicle, personal injury ordeath. For additional information andassistance, we recommend that youcontact an authorized dealer.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if youinstall them properly and adjust them tothe manufacturer's specifications. Thetrailer brakes must meet local and federalregulations.
The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combinedweight rating.

2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMTowing a Trailer

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 -
MANUAL TRANSMISSION
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 befelt due to the increased payload weight.
Your vehicle may have a temporary orconventional spare tire. A temporary sparetire is different in diameter or width, treadtype, or from a different manufacturer thanthe road tires on your vehicle. Consultinformation on the tire label or SafetyCompliance label for limitations whenusing.

•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).
•Place the transmission in neutral (N)when stopped in congested or heavytraffic during hot weather. This will aidin engine and transmission cooling andto help A/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 yourvehicle parking brake. Place thetransmission in a low gear. Place wheelchocks in front and back of the trailerwheels.
