not, or only partially moves to the
4L (4WD Low) position, perform a
shift with the transmission in N
(Neutral) and the vehicle rolling at
a speed below 3 mph (5 km/h). This
will ensure the transfer case is fully
engaged into 4L (4WD Low).
Shifting from 4L (4WD Low) to 4H (4WD High) or 2H (2WD High)

Always set the parking brake fully and make sure the gearshift is
latched in P (Park). Turn the ignition to the LOCK position and
remove the key whenever you leave your vehicle.
If the parking brake is fully released, but the brake warning lamp
remains illuminated, the brakes may not be working properly.
See your authorized dealer.
4WD Systems
4WD (when you select a 4WD mode), uses all four wheels to power the
vehicle. This increases traction, enabling you to drive over terrain and
road conditions that a conventional two-wheel drive vehicle cannot.
Power is supplied to all four wheels
through a transfer case. On 4WD
vehicles, the transfer case allows
you to select 4WD when necessary.
Information on transfer case
operation and shifting procedures
can be found in the Driving
chapter. Information on transfer
case maintenance can be found in the Maintenance and Specifications
chapter. You should become thoroughly familiar with this information
before you operate your vehicle.
Normal characteristics
On some 4WD models, the initial shift from two-wheel drive to 4x4 while
the vehicle is moving can cause some momentary clunk and ratcheting
sounds. This is the front drivetrain coming up to speed and the
automatic locking hubs engaging and is not cause for concern.
Sand
When driving over sand, try to keep all four wheels on the most solid
area of the trail. Avoid reducing the tire pressures but shift to a lower
gear and drive steadily through the terrain. Apply the accelerator slowly
and avoid spinning the wheels.
Avoid excessive speed because vehicle momentum can work against you
and cause the vehicle to become stuck to the point that assistance may
be required from another vehicle. Remember, you may be able to back
out the way you came if you proceed with caution.

Driving on hilly or sloping terrain
Although natural obstacles may make it necessary to travel diagonally up
or down a hill or steep incline, you should always try to drive straight up
or straight down. Avoid driving crosswise or turning on steep
slopes or hills . A danger lies in losing traction, slipping sideways and
possibly rolling over. Whenever driving on a hill, determine beforehand
the route you will use. Do not drive over the crest of a hill without
seeing what conditions are on the other side. Do not drive in reverse
over a hill without the aid of an observer.
When climbing a steep slope or hill,
start in a lower gear rather than
downshifting to a lower gear from a
higher gear once the ascent has
started. This reduces strain on the
engine and the possibility of stalling.
If you do stall out, do not try to
turn around because you might roll
over. It is better to back down to a
safe location.
Apply just enough power to the
wheels to climb the hill. Too much
power will cause the tires to slip,
spin or lose traction, resulting in
loss of vehicle control.
Descend a hill in the same gear you
would use to climb up the hill to
avoid excessive brake application
and brake overheating. Do not
descend in neutral; instead,
manually shift to a lower gear. Your
vehicle has anti-lock brakes, apply
the brakes steadily. Do not “pump”
the brakes.
Driving on snow and ice
4WD vehicles have advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.

Should you start to slide while driving on snowy or icy roads, turn the
steering wheel in the direction of the slide until you regain control.
Avoid sudden applications of power and quick changes of direction on
snow and ice. Apply the accelerator slowly and steadily when starting
from a full stop.
Avoid sudden braking as well. Although a 4WD vehicle may accelerate
better than a two-wheel drive vehicle in snow and ice, it won’t stop any
faster, because as in other vehicles, braking occurs at all four wheels. Do
not become overconfident as to road conditions.
Make sure you allow sufficient distance between you and other vehicles
for stopping. Drive slower than usual and consider using one of the lower
gears. In emergency stopping situations, avoid locking of the wheels. Use
a “squeeze” technique, push on the brake pedal with a steadily increasing
force which allows the wheels to brake yet continue to roll so that you
may steer in the direction you want to travel. If you lock the wheels,
release the brake pedal and repeat the squeeze technique. If your vehicle
is equipped with a Four Wheel Anti-Lock Brake System (ABS), apply the
brake steadily. Do not “pump” the brakes. Refer to the Brakes section of
this chapter for additional information on the operation of the anti-lock
brake system.
Never drive with chains on the front tires of 4WD vehicles without also
putting them on the rear tires. This could cause the rear to slide and
swing around during braking.
Maintenance and Modifications
The suspension and steering systems on your vehicle have been designed
and tested to provide predictable performance whether loaded or empty
and durable load carrying capability. For this reason, Ford Motor
Company strongly recommends that you do not make modifications such
as adding or removing parts (such as lift kits or stabilizer bars) or by
using replacement parts not equivalent to the original factory equipment.
Any modifications to a vehicle that raise the center of gravity can make
it more likely the vehicle will roll over as a result of a loss of control.
Ford Motor Company recommends that caution be used with any vehicle
equipped with a high load or device (such as ladder racks or pickup box
cover).
Failure to maintain your vehicle properly may void the warranty, increase
your repair cost, reduce vehicle performance and operational capabilities
and adversely affect driver and passenger safety. Frequent inspection of
vehicle chassis components is recommended if the vehicle is subjected to
heavy off-road usage.

Transmission operation while plowing
Operate the vehicle with the automatic transmission gearshift lever in
the D (Overdrive) position and Tow/Haul OFF.
• Shift transfer case to 4x4 LOW (4WD Low) when plowing in small
areas at speeds below 5 mph (8 km/h).
• Shift transfer case to 4x4 HIGH (4WD High) when plowing larger
areas or light snow at higher speeds. Do not exceed 15 mph
(24 km/h).
• Do not shift the transmission from a forward gear to R (Reverse) until
the engine is at idle and the wheels are stopped.
• If the vehicle is stuck, shift the transmission in a steady motion
between forward and reverse gears. Do not rock the vehicle for more
than a few minutes. The transmission and tires may be damaged or
the engine can overheat.
Do not rock the vehicle if the engine is not at normal operating
temperature. Do not rock the vehicle for more than a minute. The
transmission and tires may be damaged or the engine may
overheat.
Refer to Transmission temperature gauge in the Instrument Cluster
chapter for transmission fluid temperature information.
Do not spin the wheels at over 35 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
Removing the snowplow frame mount
A metal crossmember is included below the front bumper on Super Duty
vehicles called a “BlockerBeam”. Typical snowplow installations require
removal of this BlockerBeam to install the snowplow mounting hardware
to the vehicle frame.
The BlockerBeam must be re-installed if the snowplow
frame-mounting hardware is removed from the vehicle to ensure
proper airbag deployment in a crash.
