lock FORD BRONCO 2022 Repair Manual

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 190). It also automaticallyengages based on certain selected G.O.A.Tmodes. See G.O.A.T. Mode Control(page 242). 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.
