AUDIBLE WARNINGS
Sounds if any of the following occur:
•You switch your vehicle off beforeshifting into park (P).
•You open the driver door before shiftinginto park (P).
POWER TAKE-OFF (IF EQUIPPED)
HOW DOES THE POWER TAKE-OFF WORK
Auxiliary equipment called power take-off,or PTO, is often added to the engine ortransmission to operate utility equipment.Examples include a wheel-lift for towtrucks, cranes, tools for construction or tireservice, and pumping fluids. PTOapplications draw auxiliary horsepowerfrom the powertrain, often while thevehicle is stationary. In this condition, thereis limited cooling air flow through theradiator and around the vehicle thatnormally occurs when a vehicle is moving.The aftermarket PTO system installer,having the most knowledge of the finalapplication, is responsible for determiningwhether additional chassis heat protectionor powertrain cooling is required, andalerting the user to the safe and properoperation.
Note:Use of auxiliary equipment thatexceeds the maximum Power Take-Off(PTO) load specified in our Truck BodyBuilders Layout Book can adversely affectthe performance of the powertrain system.Refer to the Body Builders Layout Book forinstructions about the appropriateinstallation of additional equipment.

FOUR-WHEEL DRIVE
PRECAUTIONS
WARNING: Vehicles with a highercenter of gravity (utility and four-wheeldrive vehicles) handle differently thanvehicles with a lower center of gravity(passenger cars). Avoid sharp turns,excessive speed and abrupt steering inthese vehicles. Failure to drive cautiouslyincreases the risk of losing control of yourvehicle, vehicle rollover, personal injuryand death.
WARNING: Do not becomeoverconfident in the ability of four-wheeldrive vehicles. Although a four-wheeldrive vehicle may accelerate better thana two-wheel drive vehicle in low tractionsituations, it won't stop any faster thantwo-wheel drive vehicles. Always driveat a safe speed.
Truck and utility vehicles can differ fromsome other vehicles. Your vehicle could behigher to allow it to travel over roughterrain without getting stuck or damagingunderbody components. The differencesthat make your vehicle so versatile alsomake it handle differently than an ordinarypassenger car. Always maintain steeringwheel control, especially in rough terrain.Since sudden changes in terrain can resultin abrupt steering wheel motion, make sureyou grip the steering wheel from theoutside. Do not grip the spokes. Drivecautiously to avoid vehicle damage fromconcealed objects such as rocks andstumps. Drive slower in strong crosswindswhich can affect the normal steeringcharacteristics of your vehicle. Beextremely careful when driving onpavement made slippery by loose sand,water, gravel, snow or ice.
Note:Your vehicle may come with a frontair dam that can become damaged (due toreduced ground clearance) when taking yourvehicle off-road. This air dam can be takenoff by removing 15 bolts.
Parking
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: 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.
On some four-wheel drive vehicles, whenthe transfer case is in the neutral (N)position, the engine and transmissiondisconnects from the rest of the driveline.Therefore, your vehicle is free to roll evenif the automatic transmission is in park (P).Do not leave the vehicle unattended withthe transfer case in the neutral (N)position. Always set the parking brake fullyand turn off the ignition when leaving yourvehicle.
FOUR-WHEEL DRIVE
LIMITATIONS
Do not use four-wheel drive high orfour-wheel drive low mode on dry, hardsurface roads. Doing so can produceexcessive noise, increase tire wear and candamage drive components. Four-wheeldrive high or four-wheel drive low modesare intended for consistently slippery orloose surfaces. Use of four low mode onthese surfaces could produce some noise,such as occasional clunks, but should not
239
2023 Super Duty (TFH) Canada/United States of America, enUSA, Edition date: 202211, DOMFour-Wheel Drive (If Equipped)

damage drive components. Whentransitioning from consistently loose orslippery surfaces, be sure the four-wheeldrive system is not mechanically blockedonce on dry, hard surface roads intwo-wheel drive high.
Operating Four-Wheel Drive witha Spare or Worn Tires
Your four-wheel drive system is notintended to provide full function with tiresthat have different levels of wear or witha dissimilar spare tire. Incorrect use offour-wheel drive with such tires can causesystem damage.
If there is a difference in the level of wearamong tires on the vehicle or if you installa dissimilar spare tire on the vehicle, do notuse 4WD High or 4WD Low (if equipped)other than to get your vehicle unstuck.After getting your vehicle unstuck, shift to2H by performing the following steps:
1.Come to a stop on a flat, horizontalsurface
2.Shift the transmission to park (P) forautomatic transmissions and neutral(N) for manual transmissions.
3.Switch to two-wheel drive mode.
4.Shift the transmission to reverse (R).
5.Shift the transmission to drive (D) forautomatic transmissions and to firstgear for manual transmissions. Thisensures the transfer case system is nottrapped in place.
Mechanical Shift Blocking
On four-wheel drive vehicles with amechanically locked four-wheel drive highmode, the transfer case distributes torqueto the front wheels by mechanicallyinterlocking the front and rear driveshaftstogether. Various external factors affectshifting performance of this type of systemincluding, but not limited to:
•Vehicle acceleration.
•Dissimilar tire sizes.
•Steering input.
If the system detects a mechanical shiftblockage at speed after you selecttwo-wheel drive high, the message "4x4Unable to Disengage See Manual", coulddisplay momentarily. If this messagedisplays, one or more of the followingactions can relieve the mechanical shiftblock:
•Momentary acceleration.
•Momentary braking.
•Bringing the vehicle to a stop.
•Shifting the transmission to neutral andback to drive.
•Shifting the transmission to reverseand back to drive.
•Driving the vehicle around a tight turnat a slow speed.
SWITCHING FOUR-WHEEL
DRIVE ON AND OFF
A vehicle that comes with four-wheel drive,when selected, has the ability to use allfour wheels to power itself. This increasestraction, which may enable you to safelydrive over terrain and road conditions thata conventional two-wheel drive vehiclecannot.
On some four-wheel drive models, theinitial shift from two-wheel drive tofour-wheel drive while the vehicle ismoving can cause a momentary clunk andratcheting sound. These sounds are normalas the front drivetrain comes up to speedand are not cause for concern.
