Electronic Locking Differential (If Equipped)
Note:
Do not operate the system on dry hard surface roads. Doing so could lead to excessive tire noise and wear. Use the system only on consistently slippery or loose surfaces.
The system locks the left and right portions of the rear axle together to form a solid driving axle, resulting in increased rear wheel traction in certain conditions.
Press and hold the electronic differential lock button for 2 seconds to activate the system.
Note:
The lock button is on the center console.
Note:
Do not perform this operation when cruise control or trail control are selected and active. The system may not engage as expected.
The electronic differential lock can lock and unlock when the internal gears are aligned and no torque load is placed on the differential. To aid alignment, drive the vehicle in a straight line with the accelerator pedal released. Alternatively, drive slowly forward and backward while moving the steering wheel from side to side to allow the electronic differential lock to lock.
High vehicle speed and high accelerator pedal application inhibit the electronic locking differential system engagement. Follow the instruction on the instrument cluster for engagement and disengagement.
Note:
You can use the system in any drive mode 2H, 4H or 4L.
Note:
When you engage the system, the Electronic Stability Program (ESP) functions such as Stability Control, Traction Control, Hill Descent Control, Emergency stop signal, Hill Start Assist and Trailer Sway Control are deactivated, the ESP Off indicator illuminates, and the HDC on indicator turns off.
Note:
When the anti-lock braking system is operating, the system disengages.
The electronic locking differential system can affect various terrain modes. See
Principle of Operation.
Operating Electronic Locking Differential with Spare or Mismatched Tires
The size of the spare tire can affect the performance of the electronic locking differential system. When there is a significant size difference between the two rear tires, you could have limited electronic locking differential functionality. If your electronic locking differential has difficulty disengaging, release your accelerator pedal and turn the steering wheel in the opposite direction while rolling forward.
Note:
We recommend that you engage and disengage the electronic locking differential when stopped, and a spare tire is mounted on the rear axle.
