WHAT IS THE ELECTRONIC
LOCKING DIFFERENTIAL
The electronic locking differential is adevice housed in the rear axle, and canprovide additional traction when needed.
HOW DOES THE ELECTRONIC
LOCKING DIFFERENTIAL
WORK - EXCLUDING: RAPTOR
You can activate the differentialelectronically and shift it on the fly withinthe operating speed range. The electronicdifferential disengages when the vehiclespeed exceeds a set value, and reengageswhen the vehicle speed goes below a setvalue. See Switching the ElectronicLocking Differential On and Off (page285). It also engages based on certainselected drive modes. See Selecting aDrive Mode (page 363). The electroniclocking differential is for use in mud, rocks,sand, or any off-road condition where youneed maximum traction.
Note:The electronic locking differential canactivate or deactivate automatically basedon speed, four-wheel drive mode, and drivemode selection. See Switching theElectronic Locking Differential On andOff (page 285).
Note:The electronic locking differential isfor off-road use only and is not for use ondry pavement. Using the electronic lockingdifferential on dry pavement results inincreased tire wear, noise and vibration.
Note:Do not perform this operation whencruise control or trail control are selectedand active. The system may not engage asexpected.

ELECTRONIC LOCKING
DIFFERENTIAL PRECAUTIONS
Operating the 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, you may have limited electroniclocking differential functionality. If thesystem has difficulty disengaging, releasethe accelerator pedal and turn the steeringwheel in the opposite direction whenrolling. We recommend engaging anddisengaging the electronic lockingdifferential at a stop when you mount aspare on the rear axle.

ELECTRONIC LOCKING
DIFFERENTIAL INDICATORS
If both rear wheel axle shaftslock together, the indicator in thecluster is amber, providingadditional traction.
If you select the electronic lockingdifferential and the indicator in the clusteris gray or turns from amber to gray whiledriving, one of the following has occurred:
•The vehicle speed is too high.
•The accelerator pedal is too high duringan engagement attempt.
•The vehicle is experiencing an anti-lockbrake activation.
•The left and right wheel speeddifference is too high during anengagement attempt.
•The system has malfunctioned andaccompanies a check lockingdifferential message in the informationdisplay. See your dealer as soon aspossible.
Note:If the vehicle is experiencing ananti-lock braking event, the electroniclocking differential could momentarilydisengage.

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
Trail turn assist can only be used when thevehicle’s four-wheel drive system is in thefour-wheel drive high (4H), or four-wheeldrive low (4L) modes.
Trail Turn Assist cannot be used when thevehicle’s rear differential is locked. If therear differential has recently been lockedprior to Trail Turn Assist being turned on,Trail Turn Assist may not activate until itcan confirm that the rear differential isunlocked.
SWITCHING TRAIL TURN
ASSIST ON AND OFF
You can switch the trail turn assist on oroff from the features section of the vehicleon screen display.
1.Press Features on the touchscreen.
2.Press Trail Turn Assist.
3.Switch Trail Turn Assist on or off.
Once switched on, trail turn assistactivates when the:
•Vehicle speed is less than 12 mph(19.3 km/h).
•Vehicle is in four-wheel drive high (4H)or four-wheel drive low (4L).
•Rear differential is fully unlocked.
•Steering wheel is almost fully turnedto the left or right.
You can deactivate trail turn assist byperforming any of the following:
•Selecting two-wheel drive high (2H) orfour-wheel drive auto (4A).
•Switch on the rear locking differential.
•Reducing the steering wheel input.
Trail turn assist remains on, even ifdeactivated, until you switch it off in thetouchscreen. You can switch off trail turnassist through the touchscreen at any time.
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.

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.

DRIVE MODES
BAJA - RAPTOR
For high speed off-road driving.Baja mode optimizes the throttlecontrol for better response andtorque delivery.
Four-wheel drive high is the defaultfour-wheel drive mode. Four-wheel driveauto is not available in baja mode.
Off-road is the default steering andsuspension modes. All steering andsuspension modes are available.
Baja is the default exhaust mode. Allexhaust modes are available.
The system tunes the engine andtransmission controls to baja mode.
The system tunes the stability and tractioncontrols to baja mode.
The electronic locking differential isavailable at all speeds in four-wheel drive.See Switching the Electronic LockingDifferential On and Off (page 285).
Note:Using baja mode on dry, hardsurfaces could produce some vibration,driveline bind up, and potential excessivetire and vehicle wear depending on thefour-wheel drive mode selection.

•Be aware that obstacles and debrismay be beneath the water’s surface.
•Keep the doors fully closed during thewater crossing.
•After driving through water and as soonas it is safe to do so check the brakes,horn, lights, and steering wheel toconfirm those systems are functioningproperly.
Note:Engine damage can occur if waterenters the air filter.
OFF-ROAD DRIVING AIDS -RAPTOR
Selecting an Off-Road Drive Mode
Using the appropriate drive mode increasesyour vehicle's control. See Drive ModeControl (page 362).
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 274).
Using the Cameras Off-Road
Use the 360 degree camera to enhanceyour off-road experience. See 360 DegreeCamera (page 332).
Using the Rear Differential Lock
When engaged, the rear differential lockprovides additional traction to your vehicleby forcing the two rear wheels to turn atthe same speed.
Note:Rear differential lock is only availablewhen the vehicle is in 4H or 4L. SeeElectronic Locking Differential (page 284).
Using Trail Control
Trail Control provides you the ability tomaneuver the vehicle without using thethrottle and brake pedals.
The system controls acceleration andbraking in difficult off-road environments,which allows you to focus on steering. SeeTrail Control (page 312).
Trail Control Performance:
•Manages wheel slip to maximizetraction.
•Provides braking to maximize tractionin descents.
Using Trail One Pedal Drive (If
Equipped)
Trail one pedal drive allows you toaccelerate and brake using only theaccelerator pedal.
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 313).
Note:Trail one pedal drive is only availablewhen the vehicle is in 4H or 4L.
AFTER DRIVING YOUR VEHICLEOFF-ROAD - EXCLUDING: RAPTOR
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.
