tires on the ground, and they must be rolling,
not sliding or spinning.
*
[DR19925(B F )11/89]
Transmission upshift in 4x4 with transfer case in
4L may be quite firm due to large total gear
reduction. This condition is normal.
*
[DR20000(B F )11/89]
Sand
*
[DR20100(B F )11/89]
When driving over sand, try to keep all four
wheels of the vehicle on the most solid area of
the trail. Do not reduce the tire pressures but
shift to a lower gear and drive steadily through
the terrain. Apply accelerator slowly and avoid
spinning the wheels.
*
[DR20200(B F )11/89]
Mud and Water
*
[DR20300(B F )12/89]
When driving through water, determine the
depth; avoid water higher than the bottom of
the hubs (if possible) and proceed slowly. If the
ignition system gets wet, the vehicle may stall.
*
[DR20400(B F )11/89]
Once through water, always try the brakes. Wet
brakes do not stop the vehicle as effectively as
dry brakes. Drying can be improved by moving
your vehicle slowly, while applying light
pressure on the brake pedal.
*
[DR20500(B F )11/89]
After driving through mud, clean off residue
stuck to rotating driveshafts and tires. Excess
mud stuck on tires and rotating driveshafts
causes an imbalance which could damage drive
components.
*
[DR20525(B F )07/94]
NOTE: If the transmission and transfer case is
submerged in water, their fluids should
be checked and changed, if necessary.

[DR20701(B F )11/89]
Driving on Hill or Slope Terrain
*
[DR20800(B F )08/94]
When driving on a hill, it may be necessary to
travel diagonally up or down. Avoid driving
crosswise or turning on steep slopes, you could
lose traction and slip sideways. Drive straight
up, straight down or avoid the hill completely.
Know the conditions on the other side of a hill
before driving over the crest.
*
[DR20900(B F )11/89]
When climbing a steep hill, start in a lower gear,
rather than finding it necessary to downshift
from a higher gear after the ascent has started.
This reduces strain on the engine and the
possibility of stalling.
*
[DR21000(B F )11/89]
When descending a steep hill avoid sudden
braking. Rapid pumping of the brake pedal will
help slow the vehicle and still maintain steering
control.
*
[DR21101(B F )11/89]
Driving on Snow or Ice
*
[DR21200(B F )10/90]
A four-wheel drive vehicle has advantages over
two-wheel drive vehicles in snow and ice but
can skid like any other vehicle. If so equipped,
keep the vehicle in four-wheel drive if icy or
slippery conditions exist.
*
[DR21300(B F )11/89]
Avoid sudden applications of power and quick
changes of direction on snow or ice. Apply the
accelerator slowly and steadily when starting
from a full stop.
[DR21312(B F )05/95]
All utility-type and Four-Wheel Drive vehicles
have special design and equipment features to
make them capable of performing in a wide
variety of off-road applications. Specific design
characteristics give them higher centers of
gravity than ordinary passenger cars.

RWARNING
All utility and four-wheel drive vehicles
are not designed for cornering at speeds
as high as passenger cars any more than
low-slung sports cars are designed to
perform satisfactorily under off-road
conditions. Avoid sharp turns or abrupt
maneuvers in these vehicles.

Brakes
*
[DR21500( ALL)01/93]
Front Disc Brakes
*
[DR21600( ALL)03/94]
The front disc brakes are self-adjusting. They do
not require service other than periodic inspection
for pad wear.
*
[DR21900(BEF )10/94]
Rear Drum Brakes
*
[DR22000(BEF )03/95]
The rear drum brakes are self-adjusting.
Automatic adjustment occurs when the brakes
are applied while ªbacking up.º If normal
operation does not include much backing, adjust
the brakes when they seem ªlow,º using the
procedure underIf Brakes Do Not Grip Well or
Pedal is Lowin this chapter.
*
[DR22100( ALL)11/89]
Hydraulic Power Brakes
*
[DR22200(BEF )08/94]
The hydraulic brake system is made up of two
independent hydraulic circuits. One hydraulic
circuit supplies fluid to the front disc brakes and
the other hydraulic circuit supplies fluid to the
rear drum brakes. These two circuits are
supplied by a common hydraulic brake fluid
reservoir, with a fluid level sensor.
*
[DR22300( ALL)11/89]
The brake light in the instrument cluster will
light for low brake fluid in the common brake
fluid reservoir.

[DR22400( ALL)05/95]
RWARNING
An increase in pedal travel will result in
reduced braking capability. The brake
system should be checked immediately.
[DR22905(B )08/94]
Anti-lock Brake System
*
[DR22910(B )08/94]
Your vehicle is equipped with a Four Wheel
Anti-lock Braking System (4WABS). The 4WABS
helps the driver to maintain vehicle control by
preventing wheel lockup during hard braking.
*
[DR22915(BE )03/94]
The 4WABS operates with a computer that is
able to optimize vehicle control during braking
on varying tire and road conditions by
modulating the brake pressure at each of the
front wheels and the rear axle. This ªpumping
actionº is similar to the driver ªpumpingº the
brakes but happens at a much faster rate.
*
[DR22920(BE )05/95]
RWARNING
The Anti-lock system does NOT assist the
vehicle in stopping quickly on wet or icy
surfaces. Heavy braking combined with
poor road conditions could cause you to
lose steering control of your vehicle.
*
[DR22925(BE )10/94]
Using anti-lock brakes
*
[DR22930(BE )05/94]
The operation of a vehicle with 4WABS is not
similar to the operation of normal brakes. Some
differences exist and are listed below:
*
[DR22935(BE )10/94]
q
Apply the brake steadily. In the event of a
panic stop, do NOT ªpumpº the brakes.
ªPumpingº the brakes during an Anti-lock
stop will diminish braking effectiveness.

*
[DR22940(BE )10/94]
q
During an Anti-lock stop, the driver will
notice a brake pedal pulsation and hear some
noise from the engine compartment. This is
an indication that the 4WABS system is
working correctly and is normal.
*
[DR22945(BE )05/95]
RWARNING
The Anti-lock system does NOT decrease
the time necessary to apply the brakes.
Always leave enough room between the
vehicle in front of you and your vehicle.
*
[DR22950(BE )05/95]
4WABS driver warning light
[DR22955(BE )08/94]
The 4WABS computer continuously monitors the
system while driving for any electrical faults or
system malfunctions. In addition, the 4WABS
computer performs an initial system check called
bulb proveout when the vehicle ignition is
switched on. During bulb proveout, the amber
ªABSº light on the instrument cluster will
momentarily illuminate and then go out.
*
[DR22960(BE )03/93]
NOTE: After starting the vehicle and upon
initial drive-off, the driver may notice
a single pulse of the brake pedal and a
noise from the engine compartment.
This is part of the initial system check
and is normal.
[DR22965(BE )08/94]
Should a malfunction in the 4WABS system
occur, the amber ªABSº light on the instrument
cluster will come on and stay on indicating that
the antilock system has been shut down and the
vehicle needs to be serviced. Normal braking is
not affected unless the red brake warning light
is also illuminated.

[DR22970(BE )10/94]
NOTE: It is important to note that when the
ABS Warning Light is illuminated the
ABS system is disabled. The vehicle
must be serviced immediately to
restore the benefits of the Anti-lock
system.
*
[DR22975(BE )10/94]
NOTE: Mobile phones or radio transmitters
not installed by Ford Motor Company
may interfere with the Anti-lock
System. Should the Anti-lock system
activate unexpectedly or the Anti-lock
Warning Light illuminate after
installation of such a unit, have the
installation of the unit checked.
*
[DR23000(BE M)12/89]
If Brakes Do Not Grip Well or Pedal is
ªLowº
*
[DR23200(BEF )11/89]
If brakes do not grip well, it may indicate the
rear drum brakes need adjustment. To do this,
drive the vehicle in reverse at 5 mph (8 km/h)
on level, dry pavement. Stop the vehicle by
firmly applying the brakes. Repeat this
procedure four or five times.
*
[DR23250( ALL)11/89]
If during normal operation the brake pedal
seems ªlowº, it may indicate the need for a
brake system inspection and/or service. You
should have your brakes checked as soon as
possible.
*
[DR23300( ALL)02/95]
Occasional brake squeal during light to moderate
stops does not affect the function of the brake
system and is normal. However, if the squeal
becomes annoyingly loud or increases
significantly in frequency of occurrence, return
the vehicle to your dealer for inspection.

(800 km), make 10 moderately fast stops from
40 mph (65 km/h) and then perform the
self-adjustment procedure above. It may be
necessary to repeat this operation to properly
seat new brake linings and pads.
*
[DR24000( ALL)01/93]
Stopping Distances
*
[DR24100( ALL)11/89]
Stopping distances vary with different loads and
driving conditions. Use caution when
encountering new conditions and acquaint
yourself with vehicle performance. Take full
advantage of engine braking power when
slowing down.
%*
[DR24200( ALL)01/95]
Applying the Brakes
*
[DR24300( ALL)05/95]
Apply the brake pedal gradually. Use the
ªsqueezeº technique Ð push on the brake pedal
with a steadily increasing force. This allows the
wheels to continue to roll while you are slowing
down, which lets you steer properly.
*
[DR24400( ALL)05/95]
RWARNING
Do not drive with your foot resting on the
brake pedal. This will increase your
vehicle's stopping distance and may also
cause brake damage.

[DR25100( ALL)01/95]
The parking brake is not designed to stop a
moving vehicle, but you can use the parking
brake to stop your vehicle in an emergency if
the normal brakes fail. However, since the
parking brake applies only the rear brakes, the
stopping distance will increase greatly and the
handling of your vehicle will be adversely
affected.
