Driving Note: Some noise may be heard as the system shifts or engages; this is normal. Note: 4X4 high mode is not intended for use on dry pavement. Shifting between 4A (4WD AUTO) and 4H (4X4 HIGH) Move the control from 4A to 4H at a stop or while driving at any speed. The message center will display 4X4 AUTO if 4A has been selected and 4X4 HIGH if 4H has been selected. Note: 4x4 High mode is not intended for use on dry pavement. Shifting to/from 4L (4X4 LOW) 1. Bring the vehicle to a rolling speed of 3 mph (5 km/h) or less. 2. Place the gearshift in N (Neutral). 3. Move the 4WD control to the desired position. The message center will display 4X4 SHIFT IN PROGRESS during the shift. The message center will then display the system mode selected. If any of the above shift conditions are not met, the shift will not occur and the message center will display information guiding the driver through the proper range of shifting procedures. If SHIFT DELAYED PULL FORWARD is displayed in the message center, 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 (2 meters), and shift the transmission back to neutral to allow the transfer case to complete the range shift. 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 Electronic locking differential (ELD) (if equipped) The electronic locking differential (ELD) is a device housed in the rear axle which allows both rear wheels to turn at the same speed. The ELD can provide additional traction should the vehicle become stuck. The ELD is electronically activated by the driver and can be shifted on the fly within the ELD operating speed range. It is intended for use in mud, rocks, sand, or any off-road condition where maximum traction is needed. It is not intended for use on dry pavement. 325 2012 F-150 (f12) Owners Guide, 2nd Printing USA (fus)
