TRAIL TURN ASSIST –FREQUENTLY ASKED QUESTIONS
Why does Trail Turn Assist not activateafter unlocking the rear differential?
The rear differential may not be fullydisengaged. When possible, turn offthe rear axle locker while drivingstraight before using trail turn assist.If you are already in a tight turn whenyou encounter this situation, drivingthe vehicle for a short distance inreverse could allow the differential tofully disengage.

OFF-ROAD DRIVING AIDS
Bronco 4x4 Systems
Selecting an Off-Road G.O.A.TMode
Using the appropriate drive mode increasesyour vehicle's control. See G.O.A.T. ModeControl (page 260).
Note:Drive modes are selected by usingthe Goes Over Any-type of Terrain G.O.A.T.MODES controller.
Using Four-Wheel Drive
Your vehicle has a four-wheel drive systemthat offers various modes to help youoptimize traction on any off-road surface.See Four-Wheel Drive (page 195).
Using the Stabilizer BarDisconnect
The stabilizer bar disconnect improvessuspension articulation, improving tractionand comfort in rough terrain.
The vehicle's disconnect system ishydraulically actuated.
Your vehicle is capable of disconnectingunder high load. Your vehicle is alsocapable of reconnecting under allconditions.
It is not necessary for the vehicle to be onlevel ground in order to reconnect thestabilizer bar. See Stabilizer BarDisconnect (page 229).
Using the Cameras Off-Road
Use the 360 degree camera to enhanceyour off-road experience. See 360 DegreeCamera (page 247).
Using the Front and RearDifferential Lock
When engaged, the front and reardifferential lock provides additionaltraction to your vehicle by forcing eitherthe two rear wheels or two front wheels toturn at the same speed.
You can activate and deactivate the frontand rear differential lock on the fly withinthe operating speed range. See ElectronicLocking Differential (page 203).
Using Trail Control
The system works in a similar manner tocruise control in off-road conditions. TrailControl provides you the ability tomaneuver the vehicle without using thethrottle and brake pedals.
Trail Control allows you to set a speedbetween 1 mph (1.6 km/h) to 14 mph(23 km/h) in a forward motion and 1 mph(1.6 km/h) to 5 mph (8 km/h) in reverse.The system controls acceleration andbraking in difficult off-road environments,which allows you to focus on steering. SeeTrail Control (page 222).
Trail Control Performance:
•Manages wheel slip to maximizetraction.
•Removes the need for you to use bothfeet when driving in off-road situations.
•Provides braking to maximize tractionin descents.
•Gives you confidence in difficultenvironments.
Using Trail One Pedal Drive
Trail one pedal drive coordinatespropulsive and braking torque through yourapplication of the accelerator pedal tosimulate a two footed driving technique.
