Ford F-150 (2018 year). Manual - part 51

4. Apply the brake pedal. Using light finger

pressure move the white lever forward
while pulling the gearshift lever out of
the park (P) position and into the
neutral (N) position.

5. Install the access panel and rubber

mat.

6. Apply brake pedal, start your vehicle,

and release the parking brake. See your
authorized dealer as soon as possible
if this procedure is used.

If Your Vehicle Gets Stuck In Mud
or Snow

Note: Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.

Note: Do not rock your vehicle for more
than a minute or damage to the
transmission and tires may occur, or the
engine may overheat.

If your vehicle gets stuck in mud or snow,
you may rock it out by shifting between
forward and reverse gears, stopping
between shifts in a steady pattern. Press
lightly on the accelerator in each gear.

USING FOUR-WHEEL DRIVE

Note: For important information regarding
safe operation of this type of vehicle, see
General Information in the Wheels and Tires
chapter.

Note: Do not use 4H or 4L mode on dry,
hard surfaced roads. Doing so can produce
excessive noise, increase tire wear and may
damage drive components. 4H or 4L mode
is only intended for consistently slippery or
loose surfaces. Use of 4L mode on these
surfaces may produce some noise (such as
occasional clunks), but will not damage
drive components.

Note: If 4L is selected while your vehicle is
moving above 3 mph (5 km/h), the 4WD
system will not perform a shift. This is
normal and should be no reason for concern.
Refer to Shifting to or from 4L (4X4 Low)
for proper operation.

Note: You can switch on and switch off the
electronic locking differential by pulling the
4WD control (4WD vehicles) or turning the
electronic locking differential control (2WD
vehicles).  See Electronic Locking
Differential (page 216).

4WD Indicator Lights

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.

4X2

E181778

Momentarily illuminates when
2H is selected.

4X4 Auto

E181781

Continuously illuminates when
4A is selected (2-Speed
Automatic 4WD vehicles only).

4X4 HIGH

E181779

Continuously illuminates when
4H is selected.

4X4 LOW

E181780

Continuously illuminates when
4L is selected.

CHECK 4X4

Displays when a 4X4 fault is
present.

Using the Electronic Shift on the
Fly 4WD system

 (If Equipped)

E191851

2H (4X2)

For general on-road driving. Sends power
to the rear wheels only and should be used
for street and highway driving. Provides
optimal smoothness and fuel economy at
high speeds.

 (If Equipped)

4H (4X4 HIGH)

Provides mechanically locked four-wheel
drive power to both the front and rear
wheels for use in off-road or winter
conditions such as deep snow, sand or
mud. This mode is not for use on dry
pavement.

4L (4X4 LOW)

Provides mechanically locked four-wheel
drive power to both the front and rear
wheels for use on low traction surfaces,
but does so with additional gearing for
increased torque multiplication. Intended
only for off-road applications such as deep
sand, steep grades, or pulling heavy
objects. 4L (4X4 low) will not engage while
your 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.

Shifting between system modes

Note: Momentarily releasing the accelerator
pedal while a shift in progress message
displays will improve
engagement/disengagement performance.

Note: Do not perform this operation if the
rear wheels are slipping or while applying
the accelerator pedal.

Note: You may hear some noise as the
system shifts or engages; this is normal.

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: You may hear some noise as the
system shifts or engages; this is normal.

1.

Bring your vehicle to a speed of 3 mph
(5 km/h) or less.

2. Place the transmission in neutral (N).

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
present, 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 ft (1.5 m), and shift the
transmission back to neutral (N) 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 power 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 in 4A mode and disable it during
driving maneuvers when necessary.

Note: The information display may show
messages during 4WD operation.  See
Information Messages (page 122).
