FORD 2011 F-150 v.3 - Manual (Page 313)

• CHECK 4X4 - Displays when a
4X4 fault is present.
Note: When a 4X4 system fault is present, the system will typically
remain in whichever 4X4 mode was selected prior to the fault condition
occurring. It will not default to 4X2 in all circumstances. When this
warning is displayed, have your vehicle serviced by an authorized dealer.
Using a manual 4WD system (if equipped)
2H (4X2) – Power to the rear
wheels only; used for street and
highway driving. Provides optimal
smoothness and fuel economy at
high speeds.
4H (4X4 High) – Used for extra
traction such as in snow or icy roads
or in off-road situations. Not
intended for use on dry pavement.
N (Neutral) – No power to either
front or rear wheels.
4L (4X4 Low) – Uses extra gearing to provide maximum power to all
four wheels at reduced speeds. Intended only for off-road applications
such as deep sand, steep grades or pulling heavy objects. The shift lever
will not engage 4L (4X4 LOW) until the transmission is in N (neutral)
and the vehicle is moving below 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.
Shifting between 2H (4X2) and 4H (4X4 high)
• Move the transfer case lever between 2H (4X2) and 4H (4X4 high) at
a stop or any forward speed.
Note: Momentarily releasing the accelerator pedal while performing a
shift will improve engagement/disengagement times.
Note: Do not perform this operation if the rear wheels are slipping.
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 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).
