The electronic locking differential is a device housed in the rear axle that allows both rear wheels to turn at the same speed. The electronic locking differential provides additional traction should your vehicle become stuck. You can activate the differential electronically and shift it on the fly within the operating speed range. The electronic differential disengages when the vehicle speed exceeds a set value and it re-engages when the vehicle speed goes below a set value. Refer to the following table for the speeds when the electronic locking differential turns on and off. It also engages based on certain selected drive modes.  See   Principle of Operation.  The electronic locking differential is for use in mud, rocks, sand or any off-road condition where you need maximum traction. It is not for use on dry pavement.

When you switch the system on, if you do not meet the required conditions for electronic locking differential activation, the instrument cluster displays the appropriate information guiding you through the proper activation process.

Push the center of the 4WD select knob to manually activate and de-activate the electronic locking differential. An LED on the knob illuminates to indicate the system is activated.

If the indicator does not come on, or the indicator turns off when driving, one of the following has occurred:

On vehicles with an ELD, the size of the spare tire can affect performance of the system. If there is a significant difference between the two rear tires, you may have limited ELD functionality. If the electronic locking differential has difficulty disengaging, release the accelerator pedal and turn the steering wheel in the opposite direction when rolling. We recommended engaging and disengaging the ELD at a stop when you have the spare mounted on the rear axle.
