FOUR-WHEEL DRIVE
PRECAUTIONS
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.
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.

FOUR-WHEEL DRIVE
LIMITATIONS
Do not use four-wheel drive high orfour-wheel drive low mode on dry, hardsurfaced roads. Doing so can produceexcessive noise, increase tire wear and candamage driveline components. Four-wheeldrive high or four-wheel drive low mode isonly for use on consistently slippery orloose surfaces. Use of four-wheel drive lowmode on these surfaces could producesome noise, such as occasional clunks, butshould not damage driveline components.
For vehicles with an electronicshift-on-the-fly transfer case, the drivelinecould become mechanically blocked whenattempting to shift out of a four-wheeldrive mode on dry, hard surfaced roads.
Note:When your vehicle comes with the4x4 part-time selectable engagementtransfer case and you are transitioning fromconsistently loose or slippery surfaces, besure the four-wheel drive system is notmechanically blocked once you are on dry,hard surfaced roads in two-wheel drive high.
Note: In certain scenarios, where thefour-wheel drive system has difficultyengaging, a To Engage 4x4 Slow to 3 MPHor To Engage 4x4 Slow to 5 km/hmessage could appear in the instrumentcluster. You can also see this messagewhen engaging the four-wheel drive systemin extreme cold climates at the beginningof the drive cycle. Once the driveline warmsup, shifting to four-wheel drive can resumeas normal.
Operating Four-Wheel Drive witha Spare or Mismatched Tires
On four-wheel drive vehicles, the size ofthe spare tire can affect the four-wheeldrive system.
If there is a significant difference betweenthe size of the spare tire and the remainingtires, you could have limited four-wheeldrive functionality, added noise, discomfortand driveline damage.
Due to normal tire wear, your spare tire isnot necessarily the same size as youron-road tires, which makes your spare tirea dissimilar size. Use the spare tire on alimited basis only.
When driving with a dissimilar wheel andtire assembly do not:
•Exceed 50 mph (80 km/h) whenoperating in a four-wheel drive mode.
•Select a four-wheel drive mode unlessthe vehicle is stationary.
•Use a four-wheel drive mode on drypavement.
You could have limited four-wheel drivefunctionality when driving with a dissimilarwheel and tire assembly, especially whendriving in a mechanically locked four-wheeldrive mode. You can experience thefollowing:
•Additional noise from the transfer caseor other drive components.
•Difficulty shifting in and out of amechanically locked four-wheel drivemode.
•Driveline component damage.
Mechanical Shift Blocking
On vehicles with an electronicshift-on-the-fly transfer case, the transfercase distributes torque to the front wheelsby mechanically interlocking the front andrear driveshafts together. Various externalfactors can affect shifting performance ofthis type of system including, but notlimited to:
•Vehicle acceleration.
•Dissimilar tire sizes.
•High steering input.
196
2023 Bronco (TG1) Canada/United States of America, enUSA, Edition date: 202208, DOMFour-Wheel Drive

For vehicles with an electronicshift-on-the-fly transfer case, whenshifting into two-wheel drive high on dry,hard surfaced roads, we recommend thatyou follow the following procedure toreduce the likelihood of a mechanical shiftblock:
1.When driving straight, come to acomplete stop on a flat, horizontalsurface.
2.For vehicles with an automatictransmission, shift into park (P). Forvehicles with a manual transmission,press the clutch.
3.Select 2H and wait for the 2H LED tobecome solid.
4.For vehicles with an automatictransmission, shift into reverse (R). Forvehicles with a manual transmission,select reverse (R) and release theclutch. Let the vehicle roll backward upto 3 ft (1 m) and press the brake.
5.For vehicles with an automatictransmission, shift into drive (D). Forvehicles with a manual transmission,press the clutch in again, select aforward gear and release the clutch.Let the vehicle roll forward up to 3 ft(1 m).
If the system is mechanically blocked, oneor more of the following actions can relievethe mechanical shift block:
•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.

WHAT IS THE ELECTRONIC
LOCKING DIFFERENTIAL
The electronic locking differential is adevice housed in the front or rear axle and,when activated allows both wheels on thataxle to turn at the same speed. Theelectronic locking differential can provideadditional traction should your vehiclebecome stuck. You can activate thedifferential electronically and shift it on thefly within the operating speed range. Theelectronic differential automaticallydisengages when the vehicle speedexceeds a set value and it automaticallyreengages when the vehicle speed goesbelow a set value. See Switching theElectronic Locking Differential On andOff (page 203). It also automaticallyengages based on certain selected G.O.A.Tmodes. See G.O.A.T. Mode Control(page 260). The electronic lockingdifferential is for use in mud, rocks, sand,or any off-road condition where you needmaximum traction. It is not for use on drypavement.
Note:The electronic locking differentialsare for off-road use only and not for use ondry pavement. Using the electronic lockingdifferentials on dry pavement results inincreased tire wear, noise and vibration ordriveline damage.
Note:The front electronic lockingdifferential is only available in four-wheeldrive low (4L).
Note:Locking the front differential reducesyour ability to make tight turning maneuversand creates additional resistance to steeringinputs.
Note:Switching the electronic lockingdifferentials off while turning results indisengagement difficulties. If the electroniclocking differential has difficultydisengaging, release the accelerator pedaland turn the steering wheel back and forthin small increments while maintainingcontrol and following a straight line.

WHAT IS TRACTION CONTROL
The traction control system helps to avoiddrive wheel spin and loss of traction.
HOW DOES TRACTION
CONTROL WORK
If your wheels begin to spin, the loss oftraction can compromise steering controland stability of the vehicle. The tractioncontrol system applies the brakes toindividual wheels and when needed,reduces engine power at the same time toincrease traction.
SWITCHING TRACTION
CONTROL ON AND OFF
WARNING: Operating your vehiclewith the traction control disabled couldlead to an increased risk of loss of vehiclecontrol, vehicle rollover, personal injuryand death.
The system turns on each time you switchthe ignition on.
If your vehicle is stuck in mud or snow,switching traction control off may bebeneficial as this allows the wheels to spin.
Switching the System Off
The switch for the stability andtraction control system is on theinstrument panel.
When you switch the system off, amessage and an illuminated icon appearon the instrument cluster.
Use the switch again to return the tractioncontrol system to normal operation.
Note:When you switch traction control off,stability control remains fully active.
Note:When you place your vehicle intofour-wheel drive low (4L), the tractioncontrol disables. Traction control resumeswhen you put your vehicle back intotwo-wheel drive or four-wheel drive high(4H).
