CHECKING THE SEATBELTS
Check the seatbelts and child restraintsperiodically to make sure they work properlyand are not damaged. Make sure there areno nicks, tears or cuts. Replace if necessary.
Check the following seatbelt assemblies aftera crash.
•Retractors.
•Buckles.
•Front seatbelt buckle assemblies.
•Shoulder belt height adjusters.
•Shoulder belt guide on seat backrest.
•Child restraint LATCH and tether anchors.
•Attaching hardware.
Read the child restraint manufacturer'sinstructions for additional inspection andmaintenance information specific to the childrestraint.
We recommend that all seatbelt assembliesin use in vehicles involved in a crash bereplaced. However, if the crash was minorand an authorized dealer finds that the beltsdo not show damage and continue tooperate properly, they do not need to bereplaced. Seatbelt assemblies not in useduring a crash should also be checked andreplaced if either damage or improperoperation is noted.
Properly care for seatbelts. See CleaningSeatbelts (page 434).

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.

DRIVING IN SPECIAL CONDITIONS
DRIVING THROUGH MUD AND WATER
Mud
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even all-wheel drive and four-wheeldrive vehicles can lose traction in mud. Ifyour vehicle slides, steer in the direction ofthe slide until you regain control of yourvehicle. After driving through mud, clean offresidue stuck to rotating driveshafts and tires.Excess residue can cause an imbalance thatcould damage drive components.
Note:If your vehicle gets stuck in mud, itcould be rocked out by shifting betweenforward and reverse gears, stoppingbetween shifts in a steady pattern. Presslightly on the accelerator in each gear.
Note:Do not rock your vehicle if the engineis not at normal operating temperature, asdamage to the transmission could occur.
Note:Do not rock your vehicle for more thana minute, as damage to the transmissionand tires could occur or the engine couldoverheat.
Water
If you must drive though deep water, driveslowly. The water could limit traction or brakecapability. See Driving Through ShallowWater (page 386).
When driving though water, determine thedepth and avoid water higher than the centerof the wheel.
Once through water, always try the brakes.Wet brakes do not stop your vehicle asquickly as dry brakes. Apply light pressureto the brake pedal while slowly moving thevehicle to dry the brakes.
Note:Driving through deep water couldcause damage to the transmission. If thefront or rear axle is submerged in water,have the axle lubricant and power transferunit lubricant checked and changed ifnecessary.
DRIVING ON HILLY OR SLOPINGTERRAIN
WARNING: Extreme care should beused when steering the vehicle in reversedown a slope so as not to cause thevehicle to swerve out of control.
Although natural obstacles could make itnecessary to travel diagonally up or down ahill or steep incline, you should try to drivestraight up or straight down.
Note:Avoid turning on steep slopes or hills.A danger lies in losing traction, slippingsideways and possible vehicle roll over.Whenever driving on a hill, determinebeforehand the route you can use. Do notdrive over the crest of a hill without seeingwhat conditions are on the other side. Donot drive in reverse over a hill without theaid of an observer.
385
2023 Navigator (TB9) Canada/United States of America, enUSA, Edition date: 202207, DOMDriving Hints

Apply just enough power to the wheels toclimb the hill. Too much power causes thetires to slip, spin or lose traction, and youcould lose control of your vehicle. Whendescending a steep hill, do not descend thehill in neutral. Avoid sudden hard braking tokeep the front wheels rolling and to maintainyour vehicle's steering.
Note:Your vehicle has anti-lock brakes,apply the brakes steadily. Do not pump thebrakes.
Note:If your vehicle gets stuck driving onhilly or sloping terrain, it could be rocked outby shifting between forward and reversegears, stopping between shifts in a steadypattern. Press lightly on the accelerator ineach gear.
Note:Do not rock your vehicle if the engineis not at normal operating temperature, asdamage to the transmission could occur.
Note:Do not rock your vehicle for more thana minute, as damage to the transmissionand tires could occur or the engine couldoverheat.
DRIVING IN SAND
When driving over sand, try to keep all fourwheels on the most solid area of the trail. Steadily drive through the terrain. Apply theaccelerator slowly and avoid excessivewheel slip. Do not drive your vehicle in deepsand for an extended period of time. Thiscould overheat the system. A messageappears in the instrument cluster display.

DRIVING THROUGH SHALLOW
WATER
WARNING: Do not attempt to crossa deep or flowing body of water. Failure tofollow this instruction could result in theloss of control of your vehicle, personalinjury or death.
Note:Driving through standing water cancause vehicle damage.
