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.
SWITCHING THE ELECTRONIC
LOCKING DIFFERENTIAL ON
AND OFF - 4X4, EXCLUDING:
RAPTOR
The button to activate and deactivate theelectronic locking differential is in thecenter of the drive mode rotary switch.
To manually activate or deactivate theelectronic locking differential, press theelectronic locking differential button.
