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.

[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.

described underIf Brakes Do Not Grip Well or
Pedal is ªLow.º
*
[DR23800(BEF )05/95]
If pull occurs during the first 500 miles
(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.

Vehicle Loading/Towing
Information
*
[DR29450(BEF )03/91]
Your vehicle's load capacity is designated by
weight, not volume, so you cannot necessarily
use all available space with large or heavy loads.
Maximum safe vehicle weights as well as tire,
rim sizes and inflation pressures are specified for
your vehicle at the assembly plant on the Safety
Compliance Certification Label. The Certification
Label is located on the left front door lock facing
or the door latch post pillar.
*
[DR29501( ALL)12/91]
Trucks, unlike passenger cars, are basically
custom vehicles designed to carry a load. Most
owners start with a base vehicle and add
production and dealer installed and/or
aftermarket components to suit their tastes and
purposes. Even trucks that are purchased for
personal transportation only are likely to have
considerable optional equipment, such as step
bumpers and light bars, for example.

220Overloading a vehicle punishes components and
can lead to shortened service life or outright
failure.
*
[DR31001( ALL)06/92]
The capacity of the tires is included as part of
the axle and suspension system, which is to be
considered when determining the lowest rated
component. Tires are rated to carry a specific
maximum load at a specific maximum tire
pressure.
*
[DR31050( ALL)06/92]
Passenger car type tires when installed on light
trucks and multipurpose passenger vehicles are
rated at 10% lower load carrying capacity due to
the differences in vehicle usages.
*
[DR31101(BEF )07/92]
The vehicle must not be loaded to both the front
and rear GAWR because the GVWR will be
exceeded. The GAWR of the front and rear axles
exceed the GVWR when added together to allow
flexibility in fore and aft loading of cargo.
*
[DR31110( ALL)06/92]
With the tires inflated to the specified pressure
the total weight of your vehicle must not exceed
the GVWR and GAWR specified on the Safety
Compliance Certification Label. This includes full
fuel tank(s), vehicle equipment, and occupants as
well as the cargo load.
*
[DR31120( ALL)06/92]
GCWR (Gross Combined Weight Rating)
*
[DR31130( ALL)06/92]
GCWR is the maximum combined weight of the
towing vehicle (including passengers and cargo)
and the loaded trailer. The GCWR is specified
by the manufacturer to indicate the combined
maximum loaded weight that the vehicle is
designed to tow.
*
[DR31140( ALL)06/92]
Maximum Trailer Weight Rating
*
[DR31150( ALL)06/92]
The maximum weight of a trailer the vehicle is
permitted to tow. The maximum trailer weight
rating is specified by the manufacturer and is
determined by subtracting the vehicle curb

[SV25300( ALL)03/95]
Look at your tires each time you fill your fuel
tank. If one tire looks lower than the others,
check the pressure in all of them. Always follow
these precautions:
*
[SV25400( ALL)04/95]
q
Keep your tires inflated to the pressures that
are recommended.(SeeChecking the pressure
of the tireslater in this chapter.)

[SV26000( ALL)03/95]
Checking the pressure of the tires
*
[SV26100( ALL)11/89]
At least once a month, check the pressure in all
your vehicle's tires, including the spare. Use an
accurate tire pressure gauge. Check the tire
pressure when tires are cold, that is, after the
vehicle has been parked for at least one hour or
has been driven less than 3 miles (5 km). You
can find the proper cold pressure on the Safety
Compliance Certification Label.
*
[SV26150( ALL)05/95]
RWARNING
Improperly inflated tires can affect vehicle
handling and can fail suddenly, possibly
resulting in loss of vehicle control.
*
[SV26200( ALL)02/95]
Tire inspection and maintenance
*
[SV26300( ALL)02/95]
Inspect the tire treads, and remove stones, nails,
glass or other objects that may be wedged in the
tread grooves. Check for holes or cuts that may
permit air to leak from the tire, and make the
necessary repairs.
*
[SV26400( ALL)10/89]
Inspect the tire side walls for cuts, bruises and
other damage. If you suspect internal damage to
the tire, have it demounted and checked. You
may need to repair or replace it.
*
[SV26410( ALL)11/89]
Wheel inspection and maintenance
*
[SV26420( ALL)11/89]
Check for damage that would affect the runout
of the wheels. Wobble or shimmy will eventually
damage the wheel bearings.
*
[SV26430( ALL)06/93]
Front wheel bearings require periodic repacking
and adjustment as specified in theMaintenance
Schedule and Recordbooklet. Loose or worn front
wheel bearings tend to let the vehicle wander or
shimmy, and can eventually cause excessive tire
wear.
