TOWING A TRAILER PRECAUTIONS
WARNING: Do not exceed theGVWR or the GAWR specified on thecertification label.
WARNING: Towing trailersbeyond the maximum recommendedgross trailer weight exceeds the limitof your vehicle and could result inengine damage, transmission damage,structural damage, loss of vehiclecontrol, vehicle rollover and personalinjury.
WARNING: Do not exceed thelowest rating capacity for your vehicleor trailer hitch. Overloading yourvehicle or trailer hitch can impair yourvehicle stability and handling. Failureto follow this instruction could resultin the loss of control of your vehicle,personal injury or death.
WARNING: Make sure that thevertical load on the tow ball is betweenthe minimum and maximumrecommended weight at all times.Failure to follow this instruction couldresult in the loss of control of yourvehicle, personal injury or death.
WARNING: Do not cut, drill, weldor modify the trailer hitch. Modifyingthe trailer hitch could reduce the hitchrating.
WARNING: The anti-lock brakesystem does not control the trailerbrakes.
TRAILER BRAKE PRECAUTIONS
WARNING: Do not connect a trailer'shydraulic brake system directly to yourvehicle's brake system. Your vehicle maynot have enough braking power and yourchances of having a collision greatlyincrease.
WARNING: Do not tow a trailer fittedwith electric trailer brakes unless yourvehicle is fitted with a compatibleaftermarket electronic trailer brakecontroller. Failure to follow this instructioncould result in the loss of control of yourvehicle, personal injury or death. Foradditional information and assistance, werecommend that you contact an authorizeddealer.
Electric brakes and manual, automatic orsurge-type trailer brakes are safe if you installthem properly and adjust them to themanufacturer's specifications. The trailerbrakes must meet local and federalregulations.

The rating for the tow vehicle's brakingsystem operation is at the gross vehicleweight rating, not the gross combined weightrating.
Certain states require functioning trailerbrakes for trailers over a specified weight.Be sure to check state regulations for thisspecified weight.
Ford Motor Company recommends separatefunctioning brake systems for trailersweighing more than 1,500 lb (680 kg) whenloaded.
TOWING A TRAILER LIMITATIONS
The vehicle's load capacity designationis by weight, not by volume, so youcannot necessarily use all availablespace when loading a vehicle or trailer.
Note:Your vehicle could have reducedperformance when operating at highaltitudes and when heavily loaded ortowing a trailer. When driving atelevation, to match driving performanceas perceived at sea level, reduce grossvehicle weight and gross combinationweight by 2% per 1,000 ft (300 m)elevation.
LOADING YOUR TRAILER
To help minimize how trailer movementaffects your vehicle when driving:
•Load the heaviest items closest tothe trailer floor.
•Load the heaviest items centeredbetween the left and right side trailertires.
•Load the heaviest items above thetrailer axles or just slightly forwardtoward the trailer tongue. Do notallow the final trailer tongue weightto go above or below 10-15% of theloaded trailer weight. The trailertongue weight should never exceed10% of the maximum towing capacity.
•Select a ball mount with the correctrise or drop. When both the loadedvehicle and trailer are connected, thetrailer frame should be level, orslightly angled down toward yourvehicle, when viewed from the side.
TRAILER TOWING HINTS
Towing a trailer places an extra load on yourvehicle's engine, transmission, axle, brakes,tires and suspension. Periodically inspectthese components during and after anytowing operation.
When driving with a trailer or payload, a slighttakeoff vibration or shudder may be presentdue to the increased payload weight.

2023 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202207, DOMTowing a Trailer

Your vehicle may have a temporary orconventional spare tire. A temporary sparetire is different in diameter or width,tread-type, or is from a different manufacturerthan the road tires on your vehicle. Consultinformation on the tire label or SafetyCompliance label for limitations 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 thoroughly afteryou have traveled 50 mi (80 km).
•When stopped in congested or heavytraffic during hot weather, place thetransmission in park (P) to aid engine andtransmission cooling and to help A/Cperformance.
•Turn off the speed control with heavyloads or in hilly terrain. The speed controlmay turn off when you are towing onlong, 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 Assist orTow/Haul, use this feature when towing.This provides engine braking and helpseliminate excessive transmission shiftingfor optimum fuel economy andtransmission 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 and trailerif the AdvanceTrac system engages.
•Allow more distance for stopping with atrailer attached. Anticipate stops andgradually brake.
•Avoid parking on a slope. However, ifyou must park on a slope, turn thesteering wheel to point your vehicle tiresaway from traffic flow, set the parkingbrake, place the transmission in park (P)and place wheel chocks in front and backof 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 to riseabove the bottom edge of the rearbumper.
•Do not allow waves to break higher than6 in (15 cm) above the bottom edge ofthe rear bumper.
351
2023 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202207, DOMTowing a Trailer

Exceeding 6 in (15 cm) could allow water toenter vehicle components, causing internaldamage to the components and affectingdriveability, emissions and reliability.
Note:Replace the rear axle lubricantanytime the rear axle has been submergedin water.
Note:Disconnect the trailer wiring connectorbefore backing the trailer into the water.
Note:Reconnect the trailer wiring connectorafter removing the trailer from the water.

WHAT IS THE MAXIMUM LOADEDTRAILER WEIGHT
The maximum loaded trailer weight isthe highest possible weight of a fullyloaded trailer the vehicle can tow.
CALCULATING THE MAXIMUMLOADED TRAILER WEIGHT FOR YOURVEHICLE
1.Start with the gross combined weightrating for your vehicle model andaxle ratio.
2.Subtract all of the following thatapply to your vehicle:
•Vehicle curb weight.
•Hitch hardware weight, for examplea draw bar, ball, locks or weightdistributing hardware.
•Driver weight.
•Passenger weight.
•Payload, cargo and luggage weight.
•Aftermarket equipment weight.
This equals the maximum loaded trailerweight for this combination.
Note:The trailer tongue load isconsidered part of the payload for yourvehicle. Reduce the total payload by thefinal trailer tongue weight.
Note:Consult an authorized dealer todetermine the maximum trailer weightallowed for your vehicle if you are notsure.
