FOUR-WHEEL DRIVE (4WD) OPERATION (IF EQUIPPED)
For important information regarding safe operation of this type
of vehicle, seePreparing to drive your vehiclein this chapter.
When Four±wheel drive (4WD) is engaged, power is supplied to all four
wheels through a transfer case. 4WD power can be selected when
additional driving power is desired.
If equipped with the Electronic Shift 4WD System, and the
instrument panel control is moved to 4WD Low while the vehicle
is moving, the system will not engage and no damage will occur to
the 4WD system. Before 4WD Low can be engaged, the vehicle
must be at a complete stop with the brake pedal depressed and
the transmission in N (Neutral).
4H or 4L operation is not recommended on dry pavement. Doing
so could result in difficult disengagement of the transfer case,
damage to the transfer case, increased tire wear, decreased fuel
economy and difficulty turning.
Control-Trac automatic four-wheel drive system (if equipped)
Your 4x4 features the heavy-duty Control-Trac system which includes a
computer-operated transfer case. This unique system is interactive with
the road, continually monitoring and adjusting torque delivery to the
front and rear wheels to optimize vehicle control.
Positions of the Control-Trac system
The Control-Trac A4WD system
functions in three modes:
²A4WDposition delivers power to
the rear axle. If the rear wheels
lose traction, power will be
automatically delivered to the
front axle to maintain traction
throughout the slippery condition.
²4Hposition provides
mechanically locked four-wheel
drive power delivery to front and rear axles.
²4Lposition provides mechanically locked four-wheel drive when above
average power at reduced speeds is required.

²In the event of an emergency stop, avoid skidding the tires and do not
attempt any sharp steering wheel movements.
²If the vehicle goes from one type of surface to another (i.e., from
concrete to gravel) there will be a change in the way the vehicle
responds to a maneuver (steering, acceleration or barking). Again,
avoid these abrupt inputs.
Parking
On some 4WD vehicles, when the transfer case is in the N (Neutral)
position, the engine and transmission are disconnected from the rest of
the driveline. Therefore, the vehicle is free to roll even if the automatic
transmission is in P (Park) or the manual transmission is in gear. Do not
leave the vehicle unattended with the transfer case in N (Neutral)
position. Always set the parking brake fully and turn off the ignition
when leaving the vehicle.
4WD Systems (if equipped)
4WD (when you select the 4WD mode), uses all four wheels to power
itself. This increases traction, enabling you to drive over terrain and road
conditions that a conventional two-wheel drive vehicle can't.
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 theDriving
chapter. Information on transfer
case maintenance can be found in theMaintenance 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.

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, disengage
overdrive or manually shift to a
lower gear. When descending a
steep hill, avoid sudden hard
braking as you could lose control.
When you brake hard, the front
wheels can't turn and if they aren't
turning, you won't be able to steer.
The front wheels have to be turning in order to steer the vehicle. Rapid
pumping of the brake pedal will help you slow the vehicle and still
maintain steering control.
If your vehicle has anti-lock brakes, apply the brakes steadily. Do not
ªpumpº 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 as well as drive slower than usual and consider using one of
the lower gears. In emergency stopping situations, avoid locking of the
wheels. Use a ªsqueezeº 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 ªpumpº the
brakes. Refer to theBrakessection of this chapter for additional
Driving

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.
Tires, Replacement Requirements
4WD vehicles are equipped with tires designed to provide for safe ride
and handling capability.
Do not use a size and type of tire and wheel other than that originally
provided by Ford because it can affect the safety and performance of
your vehicle, which could lead to loss of vehicle control or roll over and
serious injury. Make sure all tires and wheels on the vehicle are of the
same size, type, tread design, brand and load-carrying capacity. If you
have questions regarding tire replacement, see an authorized Ford or
Lincoln/Mercury dealer.
If you nevertheless decide to equip your 4WD for off-road use with tires
larger than what Ford recommends, you should not use these tires for
highway driving.
If you use any tire/wheel combination not recommended by Ford, it may
adversely affect vehicle handling and could cause steering, suspension,
axle or transfer case failure.
Do not useºaftermarket lift kitsº or other suspension modifications,
whether or not they are used with larger tires and wheels.
These ªaftermarket lift kitsº could adversely affect the vehicle's handling
characteristics, which could lead to loss of vehicle control or roll over
and serious injury.
Tires can be damaged during off-road use. For your safety, tires that are
damaged should not be used for highway driving because they are more
likely to blow out or fail.
You should carefully observe the recommended tire inflation pressure
found on the safety compliance certification label attached to the left
front door lock facing or door latch post pillar. Failure to follow tire
pressure recommendations can adversely affect the way your vehicle
handles. Do not exceed the Ford recommended pressure even if it is less
than the maximum pressure allowed for the tire.
