Electronic Locking Differential
Once the indicator light illuminates in the information display, both rear wheel axle shafts will be locked together providing added traction.
Note:
The electronic locking differential is for off-road use only and is not for use on dry pavement. Using the electronic locking differential on dry pavement will result in increased tire wear, noise and vibration.
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 can provide additional traction should your vehicle become stuck. You can activate the differential electronically and shift it on the fly within the differential operating speed range. The 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.
The following conditions will affect the electronic locking differential:
- On 2WD vehicles and 4WD vehicles in 2H (4X2) or 4H (4X4 High), the ELD will not engage if the vehicle speed is above 20 mph (32 km/h).
- On 2WD vehicles and 4WD vehicles in 2H (4X2) or 4H (4X4 High), the ELD will automatically disengage at speeds above 25 mph (40 km/h) and will automatically reengage at speeds below 20 mph (32 km/h).
- On 4WD vehicles in 4L (4X4 Low), the ELD can be engaged at any speed and will not automatically disengage.
Activating the Electronic Locking Differential
Note:
Do not use electronic locking differential on dry, hard surfaced roads. Doing so will produce excessive noise, vibration and increase tire wear.
Note:
If the electronic locking differential has difficulty disengaging, release the accelerator pedal and turn the steering wheel in the opposite direction while rolling.
For vehicles equipped with an electronic shift 4WD system
Pull the 4WD control knob toward you.
For 2WD vehicles and vehicles equipped with a manual shift 4WD system
Turn the control to ON.
Once the indicator light illuminates in the information display, both rear wheel axle shafts will be locked together providing added traction.If the indicator does not come on, or the indicator turns off while driving, one of the following has occurred:
- The vehicle speed is too high.
- The left and right rear wheel speed difference is too high during an engagement attempt.
- The system has malfunctioned and is accompanied by CHECK LOCKING DIFFERENTIAL in the information display. See your authorized Ford dealer for assistance.
