2023 FORD SUPER DUTY Owners Manual

•If a large obstacle such as a rockcannot be avoided, choose a path thatplaces the rock directly under the tirerather than the undercarriage of thevehicle. This will help prevent damageto the vehicle.
•Ditches and washouts should becrossed at a 45° angle, allowing eachwheel to independently cross theobstacle.
Hill Climbing
WARNING: Extreme care shouldbe used when steering the vehicle inreverse down a slope so as not to causethe vehicle to swerve out of control.
•Always attempt to climb a steep hillalong the fall line of the slope and notdiagonally.
•If the vehicle is unable to make it upthe hill, DO NOT attempt to turn backdown the slope. Place the vehicle inlow range and slowly back down inreverse.
•When descending a steep slope, selectlow gear and engage hill descentcontrol. Use the throttle and brakepedals to control your descent speed.
Note:Hill descent control is functional inreverse and should be used in this situation.
DRIVING THROUGH WATERLIMITATIONS
WARNING: Do not attempt tocross a deep, fast flowing body of water.Failure to follow this instruction couldresult in the loss of control of yourvehicle, personal injury or death.
Determine the depth and speed of thecurrent before attempting a water crossing.As the water depth increases, reduce yourvehicle speed to avoid potential vehicledamage.
The key to a safe crossing is the waterdepth, current and bottom of the water'scondition. On soft bottoms, the vehiclesinks in, effectively increasing the waterlevel on the vehicle. Make sure to considerthis when determining the depth of water.Be aware that obstacles and debris maybe beneath the water’s surface.
Note:Cross flowing water at an angleheading slightly upstream.
Note:Tread lightly and avoid damage tothe environment.
Drive slowly when crossing water. Startvery slowly when entering, then buildmomentum. Proceed with a constant slowspeed lightly pressing on the accelerator.Ease off the accelerator as you reach theother side to diminish the front wave. Applythe accelerator slowly and as necessaryto climb out of the other side.
Note:Do not try to accelerate through thewater crossing.
When driving too fast in water or throughdeep water, the engine, transmission,transfer case, axles, electrical componentsor vehicle interior could ingest water.Muddy waters can reduce the coolingsystem effectiveness by depositing debrisinto the radiator. Water can causepermanent damage that may not becovered by your vehicle warranty. Seebelow for your vehicle’s capabilities.

When you are driving through water do notexceed 4 mph (7 km/h).
Never stop or shut a vehicle off whencrossing deep water unless your vehicleingested water into the engine air intake.If the engine stalls, do not attempt torestart it. Keep the doors fully closed duringa water crossing.
Extra care must be taken crossing any typeof water. Do not drive into water unlessnecessary. Only drive through areas thatare designated and approved. Determineexit points that are downstream of yourentry point to allow for drifting. If there areother vehicles ahead, wait until they haveleft the water. Unsettled water can makea safe passage more challenging.
High currents even in shallow water canwash the dirt out from around your tires orpush your vehicle across slippery rocks orsurfaces. Never attempt to cross flowingwater that is deeper than your vehicle'sground clearance. Even in low currents yourvehicle's body surface area can be pusheddownstream and out of control. Do notcross any body of water that is fast flowingand rising, wait for the flow rate to reduce.
Vehicles used to traverse water regularlyshould be periodically inspected for signsof water ingestion in all of the vehicle'sfluids. If water is found inside your vehiclefluids, service your vehicle or see anauthorized dealer.
After driving through water and as soon asit is safe to do so, check the brakes, horn,lights, and steering wheel to make sureeverything is still in working order.
AFTER DRIVING YOUR VEHICLEOFF-ROAD
WARNING: After off-road use,before returning to the road, check thewheels and tires for damage. Off-roaduse may cause damage to your wheelsand tires that can lead to tire failure, lossof vehicle control, serious injury or death.
WARNING: Always re-inflate tiresto recommended tire pressures beforethe vehicle is operated on-road. Therecommended pressure is located on thetire label or safety certification label,located on the B-pillar, inside the driver'sdoor.
Driving off-road places more stress on yourvehicle than most on-road driving. Afterdriving off-road check for damage to yourvehicle and, if necessary, have your vehiclefixed as soon as possible.
Inspect the underbody of your vehicle bychecking tires, body structure, steering,suspension, and exhaust system fordamage.
Check the radiator for mud and debris andclean as needed.
