FORD 2011 F-150 v.1 - Manual (Page 310)

Shifting to/from 4L (4X4 low)
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 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 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 (1.5 m), 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.
Using the all-wheel drive (AWD) system
(if equipped, Harley-Davidson™ only)
This system includes an electronically controlled transfer case. The
system is interactive with the road, continually monitoring and adjusting
torque delivery to the front and rear wheels to optimize traction.
2H (4X2) - Power to the rear
wheels only; used for street and
highway driving. Provides optimal
smoothness and fuel economy at
high speeds. The message center
will momentarily display “4X2” when
this mode is selected.
AWD (4X4 auto) - Power delivered
to all four wheels, as required, for
increased traction.
4H (4X4 high) - Used for extra
traction on snow covered or icy roads and in off-road situations. This
position is not recommended for use on dry pavement. This position is
only intended for severe winter or off-road conditions, such as deep
snow, ice or deep sand. The message center will display “4X4 High”
when this mode is selected.
