4. Move the transfer case shift lever
through N (Neutral) directly to 4H
(4WD High) or 4L (4WD Low).
Using the N (Neutral) position
The transfer case neutral position overrides the transmission and
puts the vehicle in neutral regardless of transmission gearshift
lever position. The vehicle can move forward or backwards.
This position should only be used
when towing the vehicle. Refer to
Wrecker towingin theRoadside
emergencieschapter.
Do not leave the vehicle unattended with the transfer case in the
N (Neutral) position. Always set the parking brake fully and turn
off the ignition when leaving the vehicle.

Driving off-road with 4WD
Your vehicle is specially equipped for driving on sand, snow, mud and
rough terrain and has operating characteristics that are somewhat
different from conventional vehicles, both on and off the road.
Maintain steering wheel control at all times, especially in rough terrain.
Since sudden changes in terrain can result in abrupt steering wheel
motion, make sure you grip the steering wheel from the outside. Do not
grip the spokes.
Drive cautiously to avoid vehicle damage from concealed objects such as
rocks and stumps.
You should either know the terrain or examine maps of the area before
driving. Map out your route before driving in the area. For more
information on driving off-road, read the “Four Wheeling” supplement in
your owner’s portfolio.
If your vehicle gets stuck
If the vehicle is stuck it may be rocked out by shifting from forward and
reverse gears, stopping between shifts, in a steady pattern. Press lightly
on the accelerator in each gear.
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 spin the wheels at over 56 km/h (35 mph). The tires may
fail and injure a passenger or bystander.

If vehicle speed drops more than 16 km/h (10 mph), the speed control
will cancel automatically. Resume speed with accelerator pedal.
If speed control cancels after climbing the hill, reset speed by pressing
and holding the SET ACCEL button to resume speeds over 50 km/h
(30 mph).
Automatic transmissions may shift frequently while driving up steep
grades. Eliminate frequent shifting by shifting out of
(Overdrive) into
a lower gear.
Driving on snow and ice
A 4WD vehicle has advantages over 2WD vehicles in snow and ice but
can skid like any other vehicle.
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.
If your vehicle is equipped with a Rear Anti-lock Brake System (RABS),
you should be careful when braking. Front brake lock-up, on any surface,
causes loss of steering control.
If your vehicle is equipped with a Four Wheel Anti-lock Brake System
(ABS), apply the brakes as you normally would. In order to allow the
ABS to operate properly, keep steady pressure on the brake pedal.
When driving on snow or ice with either braking system, allow more
stopping distance and drive slower than usual. Consider using one of the
lower gears.
VEHICLE LOADING
Before loading a vehicle, familiarize yourself with the following terms:
•Base Curb Weight: Weight of the vehicle including any standard
equipment, fluids, lubricants, etc. It does not include passengers or
aftermarket equipment.
•Payload: Combined maximum allowable weight of cargo, passengers
and optional equipment. The payload equals the gross vehicle weight
rating minus base curb weight.
•GVW (Gross Vehicle Weight): Base curb weight plus payload
weight. The GVW is not a limit or a specification.

Do not attempt to service, repair, or modify the Air Bag
Supplemental Restraint System or its fuses. See your Ford or
Lincoln-Mercury dealer.
Engine temperature while plowing
When driving with a plow, your
engine may run at a higher
temperature than normal because
the attached snowplow blade will
restrict airflow to the radiator.
If you are driving more than 24 km (15 miles) at temperatures above
freezing, angle the plow blade either full left or full right to provide
maximum airflow to the radiator.
If you are driving less than 24 km (15 miles) at speeds up to 64 km/h
(40 mph) in cold weather, you will not need to worry about blade
position to provide maximum airflow.
4WD operation while plowing
•Shift transfer case to 4x4 LOW (4WD Low) when plowing in small
areas at speeds below 8 km/h (5 mph).
•
Shift transfer case to 4x4 HIGH (4WD High) when plowing larger areas
or light snow at higher speeds. Do not exceed 24 km/h (15 mph).
•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 spin the wheels at over 35 mph (55 km/h). The tires may
fail and injure a passenger or bystander.
