Driving Using the electronic shift on the fly (ESOF) 4WD system (if equipped) 2H (4X2) - Delivers power to the rear wheels only. This mode is appropriate for normal on-road driving and provides the best fuel economy and smoothness. 4H (4X4 HIGH) - provides mechanically locked four-wheel drive power to the front and rear wheels. This position is not recommended for use on dry pavement. This position is only intended for off-road or winter conditions, such as deep snow, ice or shallow sand. Note: Do not use 4H (4X4 HIGH) on dry, hard surfaced roads. Doing so can produce excessive noise and increased tire wear. 4H (4X4 HIGH) is only intended for consistently slippery or loose surfaces. 4L (4X4 LOW) - Provides mechanically locked four-wheel drive when extra power at reduced speeds is required. This position is not recommended for use on dry pavement. Use this position for off-road low-speed operation or when extra power is required, such as climbing steep grades, going through deep sand or pulling a boat out of the water. 4L (4X4 LOW) will not engage while the vehicle is moving above 3 mph (5 km/h); this is normal and should be no reason for concern. Refer to Shifting to/from 4L (4X4 LOW) for proper operation. Note: Do not use 4L (4X4 LOW) on dry, hard surfaced roads. Doing so can produce excessive noise and increased tire wear. 4L (4X4 LOW) is only intended for consistently slippery or loose surfaces. Shifting between 2H (4X2) and 4H (4X4 High) Move the 4WD control between 2H (4X2) and 4H (4X4 HIGH) at any forward speed. The message center will display 4X4 SHIFT IN PROGRESS during the system shift. 4X4 HIGH will display in the message center if 4H is selected and 4X2 will momentarily display in the message center if 2H is selected. If SHIFT DELAYED PULL FORWARD is displayed in the message center during the mode shift, transfer case gear tooth blockage is present. To alleviate this condition, place the transmission in a forward gear and move the vehicle forward approximately 5 feet (2 meters) to allow the transfer case to complete the mode shift. 322 2012 F-150 (f12) Owners Guide, 2nd Printing USA (fus)

Using the electronic shift on the fly (ESOF) 4WD system
(if equipped)
2H (4X2)
- Delivers power to the
rear wheels only. This mode is
appropriate for normal on-road
driving and provides the best fuel
economy and smoothness.
4H (4X4 HIGH)
- provides
mechanically locked four-wheel
drive power to the front and rear
wheels. This position is not
recommended for use on dry
pavement. This position is only
intended for off-road or winter conditions, such as deep snow, ice or
shallow sand.
Note:
Do not use 4H (4X4 HIGH) on dry, hard surfaced roads. Doing so
can produce excessive noise and increased tire wear. 4H (4X4 HIGH) is
only intended for consistently slippery or loose surfaces.
4L (4X4 LOW)
- Provides mechanically locked four-wheel drive when
extra power at reduced speeds is required. This position is not
recommended for use on dry pavement. Use this position for off-road
low-speed operation or when extra power is required, such as climbing
steep grades, going through deep sand or pulling a boat out of the water.
4L (4X4 LOW) will not engage while the vehicle is moving above 3 mph
(5 km/h); this is normal and should be no reason for concern. Refer to
Shifting to/from 4L (4X4 LOW) for proper operation.
Note:
Do not use 4L (4X4 LOW) on dry, hard surfaced roads. Doing so
can produce excessive noise and increased tire wear. 4L (4X4 LOW) is
only intended for consistently slippery or loose surfaces.
Shifting between 2H (4X2) and 4H (4X4 High)
Move the 4WD control between 2H (4X2) and 4H (4X4 HIGH) at any
forward speed. The message center will display
4X4 SHIFT IN
PROGRESS
during the system shift.
4X4 HIGH
will display in the
message center if 4H is selected and
4X2
will momentarily display in the
message center if 2H is selected.
If
SHIFT DELAYED PULL FORWARD
is displayed in the message
center during the mode shift, transfer case gear tooth blockage is
present. To alleviate this condition, place the transmission in a forward
gear and move the vehicle forward approximately 5 feet (2 meters) to
allow the transfer case to complete the mode shift.
