192 [DR16025(ALL)05/94]How the Electronic 4-Wheel Drive (E-4WD)
System Works
[DR16036(ALL)03/90]
Under normal driving conditions, when the road
is firm, dry and level, the engine power is
distributed one-third to the front axle and
two-thirds to the rear axle. However, if a wheel
begins to slip, the microprocessor will sense this
condition and signal the system to transmit more
power to the axle with more traction. (You may
feel a momentary surge of power.)
[DR16046(ALL)06/95]
NOTE: The microprocessor is disabled when
the brakes are applied or when the
transmission selector is in the P (Park)
or N (Neutral) positions.
[DR16055(ALL)05/94]
Driving Your Electronic 4-Wheel Drive
(E-4WD) Vehicle
[DR16065(ALL)03/95]
Since your E-4WD vehicle is unique, follow these
steps to be safe:
[DR16075(ALL)03/95]
q
Avoid unnecessary turns or other maneuvers
that could cause loss of control and possible
injury.
[DR16076(ALL)06/95]
q
Use the same size and type of tire and wheel
as originally provided for your vehicle and
inflate the tires to the manufacturer's
recommended air pressure.
[DR16077(ALL)03/95]
q
Become familiar with your vehicle's operating
characteristics and study this Owner Guide
for specific operating instructions. Be sure all
occupants wear the safety belts provided.
Drive cautiously, defensively, and at speeds
safe for current road conditions.

Vehicle Loading/Towing
Information
*
[DR29450(ALL)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.
[DR29504(ALL)08/95]
RWARNING
It is extremely dangerous to ride in a
cargo area, inside or outside of a vehicle.
In a collision, people riding in these areas
are more likely to be seriously injured or
killed.

[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(ALL)05/95]
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
exceeds 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)05/95]
The maximum trailer weight rating is the
maximum weight of a trailer the vehicle is
permitted to tow. It is specified by the
manufacturer and is determined by subtracting
the vehicle curb weight for each
engine/transmission combination, any required
option weight for trailer towing and the weight
of the driver from the GCWR for the towing
vehicle.

[RE03500(ALL)04/95]
After the vehicle is started, let it idle for a while
to let the engine ªrelearnº its idle conditions.
Drive it around for a while with all electrical
accessories turned off to let the battery recharge.
You may need to use a battery charger to fully
recharge the battery.

Changing a Tire
*
[RE03700(ALL)01/95]
If you get a flat tire while you are driving, do
not apply the brake heavily. Instead, gradually
decrease the speed. Hold the steering wheel
firmly and slowly move to a safe place on the
side of the road. Park on a level spot, turn off
the ignition, set the parking brake, and turn on
the hazard flashers.

[RE03800(ALL)03/95]
The Conventional Spare Tire
*
[RE03900(ALL)01/95]
If you have the conventional spare tire, you can
use it as a spare or as a regular tire. This spare
tire is identical to the other tires that come with
your vehicle, although the wheel may not match.
%*
[RE04000(ALL)03/95]
The Temporary Spare Tire
*
[RE04100(ALL)03/95]
You may have a high pressure temporary spare
tire. This spare tire is smaller than a regular tire
and is designed for emergency use only. Use it
only when you get a flat tire and replace it as
soon as you can. This spare tire is marked with
the words ªTEMPORARY USE ONLYº so that
you can easily identify it.

RWARNING
If you use the temporary spare tire
continuously or do not follow these
precautions, the tire could fail, causing
you to lose control of the vehicle, possibly
injuring yourself or others.
[RE04250(ALL)05/95]
RWARNING
The tire size on the E-4WD must be
maintained.
[RE04260(ALL)06/95]
Your vehicle may have a full diameter mini
spare or a full size tire. This full diameter mini
spare is special for the E-4WD and another mini
spare from another vehicle can not be
substituted without the possibility of damage to
your vehicle. All tires should be inflated to the
manufacturer's recommended pressures.
*
[RE04275(ALL)05/95]
RWARNING
To avoid injury, never run the engine
with one wheel off the ground, such as
when changing a tire.
*
[RE04280(ALL)10/94]
Extended use of other than matching size spare
tires on a Traction-Lok axle could result in a
permanent reduction in effectiveness. This loss of
effectiveness does not affect normal driving and
should not be noticeable to the driver.

When you drive with the temporary spare tire,
DO NOT:
*
[RE04400(ALL)01/95]
q
exceed 50 mph (80 km/h) under any
circumstances.
*
[RE04500(ALL)01/95]
q
load your vehicle so that it is heavier than
the maximum vehicle load rating listed on
the tire decal.

[RE04600(ALL)01/95]
q
tow a trailer.
*
[RE04700(ALL)01/95]
q
use tire chains on this tire.
*
[RE04800(ALL)01/95]
q
try to repair the temporary spare tire or
remove it from its wheel.
*
[RE04900(ALL)01/95]
q
use the wheel for any other type of vehicle.
*
[RE05000(ALL)01/95]
q
drive through an automatic car wash with
this tire. Because the temporary spare tire is
smaller than a conventional tire, it reduces
the ground clearance. Your vehicle may get
caught in the rails and it could be damaged.

Spare Tire Location
[RE05200(ALL)03/95]
If your vehicle is a standard length van model,
the spare tire is mounted inside a carrier at the
left rear quarter panel. To remove the spare tire,
remove the wing nut and plate. A flat tire can
be temporarily stowed in the same location.
