FORD 2014 F-150 Raptor v.2 - Manual (Page 155)

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. 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 or 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. Use of 4L (4X4
LOW) on these surfaces may produce some
noise (such as occasional clunks), but will
not damage drive components.
Note: The AdvanceTrac system has the
ability to take over control of the transfer
case clutch and disable it during driving
maneuvers when necessary.
Shifting between system modes
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.
You can move the control from 2H or 4H
at a stop or while driving. The information
display may display a message indicating
a 4X4 shift is in progress. Once the shift is
complete the message center will then
display the system mode selected.
Shifting to or 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.
If SHIFT DELAYED PULL FORWARD
displays in the information display, a
transfer case gear tooth blockage is
present. To alleviate this condition, place
the transmission in a forward gear, move
your vehicle forward approximately 5 feet
(1.5 meters), and shift the transmission
back to N neutral to allow the transfer case
to complete the range shift.
Using the 2-Speed Automatic 4WD
System
(If Equipped)
This system includes an electronically
controlled transfer case with a high
capacity clutch. The system is interactive
with the road, continually monitoring and
adjusting torque delivery to the front and
rear wheels to optimize traction.
Note: The AdvanceTrac system has the
ability to take over control of the transfer
case clutch and disable it during driving
maneuvers when necessary.
