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.

DIFFERENTIAL INDICATORS
Rear locking differentialIndicator.
Front locking differentialIndicator.
If the front or rear indicator in the clusteris amber, both wheels of the indicated axleare locked together providing additionaltraction.
If the electronic locking differential isselected and the indicator in the cluster isgray or turns from amber to gray whiledriving, one of the following has occurred:
•Your vehicle speed is too high.
•The accelerator pedal is too high duringan engagement attempt.
•Your vehicle is experiencing ananti-lock brake activation.
•The left and right wheel speeddifference is too high during anengagement attempt.
If the electronic locking differential isselected and the indicator in the clusterdoes not illuminate, one of the followinghas occurred:
•The electronic locking differential is notallowed in the current G.O.A.T modeand is accompanied by SELECTEDLOCKING DIFFERENTIAL NOTAVAILABLE IN CURRENT Drive Modein the instrument cluster display.
•The electronic locking differential is notallowed in the current 4x4 mode andis accompanied by SELECTEDLOCKING DIFFERENTIAL NOTAVAILABLE IN CURRENT 4x4 MODE inthe instrument cluster display.
•The system has malfunctioned and isaccompanied by CHECK LOCKINGDIFFERENTIAL in the instrumentcluster display. See your authorizeddealer for assistance.

•The front electronic locking differentialdoes not engage if your vehicle speedis above 20 mph (32 km/h) infour-wheel drive low (4L).
•Based on G.O.A.T mode selection, theelectronic locking differentialautomatically disengages at speedsabove 25 mph (41 km/h) andautomatically re-engages at speedsbelow 20 mph (32 km/h).
•The electronic locking differential maynot engage if you press youraccelerator pedal during anengagement attempt. A message maydisplay in the instrument displayguiding you to release the acceleratorpedal.
•In four-wheel drive low (4L), the frontelectronic locking differentialautomatically disengages at speedsabove 25 mph (41 km/h) andautomatically re-engages at speedsbelow 20 mph (32 km/h).
•The AdvanceTrac system has theability to take over control of theelectronic locking differential anddisable it during driving maneuverswhen necessary.
Operating Electronic LockingDifferential With a Spare orMismatched Tires
On vehicles with an electronic lockingdifferential, the size of the spare tire canaffect performance of the system. If thereis a significant difference between the tworear tires or two front tires, you may havelimited electronic locking differentialfunctionality. If the electronic lockingdifferential has difficulty disengaging,

WHAT IS TRAIL TURN ASSIST
Trail turn assist can reduce the turningradius of your vehicle by applying thebrakes to the inside rear wheel inlow-speed, high steering-angle maneuvers.
TRAIL TURN ASSIST
PRECAUTIONS
Note:Do not use trail turn assist on dry,hard surfaced roads. Doing so can produceexcessive noise, increase tire wear and maydamage drive line, or braking components.Trail turn assist is only intended for slippery,or loose surfaces.
You may hear noise from the anti-lockbrake system while trail turn assist isactive. This is normal operation.
TRAIL TURN ASSIST
LIMITATIONS
You can only use trail turn assist when thesystem is in four-wheel drive high (4H), orfour-wheel drive low (4L) mode.
You cannot use trail turn assist with therear differential engaged. If the systemdetects that the rear differential hasrecently been engaged, it may not activatetrail turn assist until it can confirm that therear differential is disengaged.
If the vehicle’s rear differential is engagedwhen pressing the trail turn assist button,the rear differential will attempt todisengage to allow for trail turn assistoperation.
SWITCHING TRAIL TURN
ASSIST ON AND OFF
Bronco Off-Road Features
While in four-wheel drive high (4H) orfour-wheel drive low (4L), press the trailturn assist button to turn the feature on.trail turn assist will be on at this time butwill not activate until:
•Vehicle speed is less than 12 mph(19.3 km/h).
•Rear differential is fully unlocked.
•Steering wheel is almost fully turnedto the left or right.
You can turn off trail turn assist by doingany of the following:
•Pressing the trail turn assist buttonagain.
•Selecting a two-wheel drive high (2H),or four-wheel drive auto (4A).
•Turning on the rear locking differential.
TRAIL TURN ASSIST
INDICATORS
When trail turn assist is on, oneof these two indicators will bedisplayed, depending on thedirection of the vehicle’s lastturn. When the feature is on butnot in use, the indicator light willbe gray. When the feature is active theindicator light will be green.
