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.

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 190).
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 207).
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.
Use this when driving over large obstacles,such as rocks or logs, to help maintain aconstant vehicle speed.
In 4H, the system offers lift pedal brakingand auto hill hold functionality. See WhatIs Trail One Pedal Drive (page 208).
Note:Trail one pedal drive is only availablewhen the vehicle is in 4H or 4L.
Using Trail Turn Assist
The feature reduces the turn radius of thevehicle on off-road surfaces.
The system reduces driver effort tonegotiate difficult off-road terrain byallowing the vehicle to make a tight turnin a single maneuver that might otherwiserequire a three point turn. See Trail TurnAssist (page 212).
Note:Trail turn assist is only available whenthe vehicle is in 4H or 4L.
Note:Trail turn assist cannot activate if therear differential is locked.
What Are Rock Rails (If Equipped)
Rock rails protect the rocker and body sidefrom damage and provide a sliding surfaceto allow the vehicle to cross boulders androck ledges.
Rock rails also can act as a pivot point tosharply turn the vehicle in tight spaces withhigh walls or rocks present.
AFTER DRIVING YOUR VEHICLEOFF-ROAD
WARNING: After off-road use,before returning to the road, check thewheels and tires for damage. Off-roaduse may cause damage to your wheelsand tires that can lead to tire failure, lossof vehicle control, serious injury or death.
