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.
