Driving in Special Conditions WithFour-Wheel drive (4WD)
Note:Use of the 4WD system in slippery,deep snow, and sand drive modes on drysurfaces could produce some vibration,driveline bind up, or excessive tire wear asthese drive modes are intended for slipperyand loose surfaces.
Note:The design of 4WD vehicles are fordriving on sand, snow, mud and rough roadsand have operating characteristics that aresomewhat different from conventionalvehicles, both on and off the highway.
Basic Operating Principles in SpecialConditions
•Drive slower in strong crosswinds whichcan affect the normal steeringcharacteristics of your vehicle.
•Be extremely careful when driving onpavement made slippery by loose sand,water, gravel, snow or ice.
If Your Vehicle Goes Off the Edge of thePavement
•If your vehicle goes off the edge of thepavement, slow down, but avoid severebrake application, ease the vehicleback onto the pavement only afterreducing your speed. Do not turn thesteering wheel too sharply whilereturning to the road surface.
•It could be safer to stay on the apronor shoulder of the road and slow downgradually before returning to thepavement. You could lose control if youdo not slow down or if you turn thesteering wheel too sharply or abruptly.
•It often could be less risky to strikesmall objects, such as highwayreflectors, with minor damage to yourvehicle rather than attempt a suddenreturn to the pavement which couldcause the vehicle to slide sideways outof control or rollover. Remember, yoursafety and the safety of others shouldbe your primary concern.
If Your Vehicle Gets Stuck
WARNING: Apply the parkingbrake, shift into park (P), switch theignition off and remove the key beforeyou leave your vehicle. Failure to followthis instruction could result in personalinjury or death.
WARNING: If the parking brake isfully released, but the brake warninglamp remains illuminated, the brakesmay not be working properly. Have yourvehicle checked as soon as possible.
WARNING: Do not spin the wheelsat over 34 mph (55 km/h). The tires mayfail and injure a passenger or bystander.
205
2023 Explorer (CTW) Canada/United States of America, enUSA, Edition date: 202209, First-PrintingFour-Wheel Drive (If Equipped)

If your vehicle gets stuck in mud or snowyou can rock it out by shifting betweenforward and reverse gears, stoppingbetween shifts, in a steady pattern. Presslightly on the accelerator in each gear.
If your vehicle comes with AdvanceTrac®with Roll Stability Control™, it could bebeneficial to disengage the AdvanceTrac®with Roll Stability Control™ system whileattempting to rock the vehicle.
Note:Do not rock the vehicle if the engineis not at normal operating temperature ordamage to the transmission could occur.
Note:Do not rock the vehicle for more thana few minutes or damage to thetransmission and tires could occur or theengine could overheat.
Emergency Maneuvers
•In an unavoidable emergency situationwhere a sudden sharp turn must bemade, remember to avoid"over-driving" your vehicle (forexample, turn the steering wheel onlyas rapidly and as far as required toavoid the emergency). Excessivesteering can result in less vehiclecontrol, not more. Additionally, smoothvariations of the accelerator and/orbrake pedal pressure should be utilizedif changes in vehicle speed are called
for. Avoid abrupt steering, accelerationor braking which could result in anincreased risk of loss of vehicle control,vehicle rollover and/or personal injury.Use all available road surface to returnthe vehicle to a safe direction of travel.
•In the event of an emergency stop,avoid skidding the tires and do notattempt any sharp steering wheelmovements.
•If the vehicle goes from one type ofsurface to another (i.e., from concreteto gravel) there is a change in the waythe vehicle responds to a maneuver(steering, acceleration or braking).Again, avoid these abrupt inputs.
Sand
When driving over sand, try to keep all fourwheels on the most solid area of the trail.Avoid reducing the tire pressures but shiftto a lower gear and drive steadily throughthe terrain. Apply the accelerator slowlyand avoid spinning the wheels.
Avoid excessive speed because vehiclemomentum can work against you andcause the vehicle to become stuck to thepoint that assistance could be requiredfrom another vehicle. Remember, youcould be able to back out the way youcame if you proceed with caution.
Mud and Water
If you must drive through high water, driveslowly. Traction or brake capability couldbe limited.
Note:Driving through deep water coulddamage your vehicle.
When driving through water, determine thedepth; avoid water higher than the bottomof the hubs (if possible) and proceedslowly. If the ignition system gets wet, thevehicle could stall.
206
2023 Explorer (CTW) Canada/United States of America, enUSA, Edition date: 202209, First-PrintingFour-Wheel Drive (If Equipped)

Once through water, always try the brakes.Wet brakes do not stop the vehicle aseffectively as dry brakes. Drying can beimproved by moving your vehicle slowlywhile applying light pressure on the brakepedal.
Be cautious of sudden changes in vehiclespeed or direction when you are driving inmud. Even 4WD vehicles can lose tractionin slick mud. As when you are driving oversand, apply the accelerator slowly andavoid spinning your wheels. If the vehicledoes slide, steer in the direction of the slideuntil you regain control of the vehicle.
After driving through mud, clean off residuestuck to rotating driveshafts and tires.Excess mud stuck on tires and rotatingdriveshafts causes an imbalance thatcould damage drive components.
“Tread Lightly” is an educational programdesigned to increase public awareness ofland-use regulations and responsibilitiesin our nations wilderness areas. Ford MotorCompany joins the U.S. Forest Service andthe Bureau of Land Management inencouraging you to help preserve ournational forest and other public and privatelands by “treading lightly.”
Driving on Hilly or Sloping Terrain
Although natural obstacles could make itnecessary to travel diagonally up or downa hill or steep incline, you should alwaystry to drive straight up or straight down.
Note: Avoid driving crosswise or turning onsteep slopes or hills. A danger lies in losingtraction, slipping sideways and possiblyrolling over. Whenever driving on a hill,determine beforehand the route you willuse. Do not drive over the crest of a hillwithout seeing what conditions are on theother side. Do not drive in reverse over a hillwithout the aid of an observer.
When climbing a steep slope or hill, startin a lower gear rather than downshifting toa lower gear from a higher gear once theascent has started. This reduces strain onthe engine and the possibility of stalling.
If you do stall out, do not try to turn aroundbecause you might roll over. It is better toback down to a safe location.
Apply just enough power to the wheels toclimb the hill. Too much power can causethe tires to slip, spin or lose traction,resulting in loss of vehicle control.
Descend a hill in the same gear you woulduse to climb up the hill to avoid excessivebrake application and brake overheating.Do not descend in neutral; instead,disengage overdrive or manually shift to alower gear. When descending a steep hill,avoid sudden hard braking as you couldlose control. The front wheels have to beturning in order to steer the vehicle.
