FORD 2013 F-150 v.2 - Manual (Page 225)

Activating the Electronic Locking Differential
Note: Do not use ELD on dry, hard surfaced roads. Doing so will
produce excessive noise and vibration and increase tire wear.
Note: If the ELD has difficulty disengaging, release the accelerator pedal
and turn the steering wheel in the opposite direction while rolling.
The ELD can be turned on by pulling the 4WD
control knob toward you (4x4 vehicles) or by
turning the ELD control knob from OFF to ON
(4x2 vehicles).
Once the indicator light is displayed in the message center,
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 will be accompanied by a CHECK
LOCKING DIFFERENTIAL message in the information displays screen.
How Your Vehicle Differs From Other Vehicles
WARNING: Vehicles with a higher center of gravity such as
utility and four-wheel drive vehicles handle differently than
vehicles with a lower center of gravity. Utility and four-wheel drive
vehicles are not designed for cornering at speeds as high as passenger
cars any more than low-slung sports cars are designed to perform
satisfactorily under off-road conditions. Avoid sharp turns, excessive
speed and abrupt maneuvers in these vehicles. Failure to drive
cautiously could result in an increased risk of loss of vehicle control,
vehicle rollover, personal injury and death.
Truck and utility vehicles can differ from some other vehicles. Your
vehicle may be higher to allow it to travel over rough terrain without
getting hung up or damaging underbody components.
