If SHIFT DELAYED PULL FORWARD is displayed in the information display, transfer case gear tooth blockage is present. To alleviate this condition, place the transmission in a forward gear, move the vehicle forward approximately 5 feet (1.5 m), and shift the transmission back to neutral to allow the transfer case to complete the range shift. Electronic Locking Differential (ELD) (If Equipped) Note: The ELD is designed for off-road use only and is not intended for use on dry pavement. Using the ELD on dry pavement will result in increased tire wear, noise and vibration. The electronic locking differential (ELD) is a device housed in the rear axle which allows both rear wheels to turn at the same speed. It provides added traction on slippery and/or off road surfaces, particularly when one wheel is on a poor traction surface. The ELD may be locked or unlocked by the vehicle operator and can be engaged or disengaged on the fly. When the axle is unlocked it will function like a standard rear axle. When the axle is locked it will not allow the rear wheels to rotate at different speeds when turning. The ELD is affected by the following conditions: • 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. 2013 F-250/350/450/550 (f23) Owners Guide gf, 3rd Printing, December 2012 USA (fus)

Shifting to/from 4L (4X4 low)

Note:

Some noise may be heard as the system shifts or engages; this is

normal.

Note:

4x4 low mode is not intended for use on dry pavement.

1. Bring the vehicle to a speed of 3 mph (5 km/h) or less.

2. Place the transmission in N (Neutral).

3. Move the 4WD control to the desired position.

The information display will display a message indicating a 4X4 shift is

in progress. The information display will then display the system mode

selected. If any of the above shift conditions are not met, the shift will

not occur and the information display will display information guiding the

driver through the proper shifting procedures.

SHIFT DELAYED PULL FORWARD

is displayed in the information

display, transfer case gear tooth blockage is present. To alleviate this

condition, place the transmission in a forward gear, move the vehicle

forward approximately 5 feet (1.5 m), and shift the transmission back

to neutral to allow the transfer case to complete the range shift.

Electronic Locking Differential (ELD) (If Equipped)

Note:

The ELD is designed for off-road use only and is not intended for

use on dry pavement. Using the ELD on dry pavement will result in

increased tire wear, noise and vibration.

The electronic locking differential (ELD) is a device housed in the rear

axle which allows both rear wheels to turn at the same speed. It provides

added traction on slippery and/or off road surfaces, particularly when

one wheel is on a poor traction surface. The ELD may be locked or

unlocked by the vehicle operator and can be engaged or disengaged on

the fly. When the axle is unlocked it will function like a standard rear

axle. When the axle is locked it will not allow the rear wheels to rotate

at different speeds when turning.

The ELD is affected by the following conditions:

•

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.
