The speedometer tells you how many miles
(kilometers) per hour your vehicle is moving.
*
[IS12750(ALL)03/96]
Your vehicle contains a speedometer which
receives its input from the Anti-Lock brake
sensor. The speedometer is also used to provide
a speed signal for correct operation of the
vehicle's Powertrain Control Module (PCM),
electronic transmission, and speed control (if so
equipped). Because of this, it is very
IMPORTANT to change the speedometer's
internal conversion constant if the size of the
tires on the vehicle is changed. Changing the
conversion constant to the proper value when

Traction-Lok Rear Axle
(If equipped)
*
[GF15700(ALL)05/96]
This axle provides added drive away traction on
slippery surfaces, particularly when one or more
wheels are on a surface with poor traction.
*
[GF15800(ALL)03/96]
Extended use of other than matching size tires
on a Traction-Lok rear 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.
[GF16005(ALL)01/96]Electronic 4-Wheel Drive (E-4WD)
(If equipped)
[GF16015(ALL)01/96]
If your vehicle is equipped with the E-4WD
option, power is provided to all four wheels
whenever you press the accelerator pedal. It
improves both handling and traction during
difficult driving conditions, adjusting
automatically to your driving needs. Because the
entire E-4WD system is controlled by a
microprocessor, your vehicle is not equipped
with the switch or shift lever used with most
traditional 4WD vehicles. The microprocessor
does all the adjusting for you.

178 [GF16025(ALL)01/96]How the Electronic 4-Wheel Drive (E-4WD)
System Works
[GF16036(ALL)01/96]
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.)
[GF16046(ALL)01/96]
NOTE: The microprocessor is disabled when
the brakes are applied or when the
transmission selector is in the P (Park)
or N (Neutral) positions.

Driving Your Electronic 4-Wheel Drive
(E-4WD) Vehicle
[GF16065(ALL)01/96]
Since your E-4WD vehicle is unique, follow these
steps to be safe:
[GF16075(ALL)01/96]
q
Avoid unnecessary turns or other maneuvers
that could cause loss of control and possible
injury.
[GF16076(ALL)01/96]
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.
[GF16077(ALL)01/96]
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.

[GF29450(ALL)01/96]
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.

The Temporary Spare Tire
%*
[ER04100(ALL)02/96]
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.
*
[ER04200(ALL)02/96]
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.

RWARNING
The tire size on the E-4WD must be
maintained.
[ER04260(ALL)01/96]
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.

If your vehicle has aluminum wheels, you may
demount the full size, non-temporary spare
tire (if so equipped) and remount on an
aluminum wheel to rotate the spare tire into
your vehicle's rotation pattern. Rebalance the
wheel.
[MC27100(ALL)04/96]
You may discover uneven outside shoulder wear
on your vehicle's front radial tires if you drive
often in the city and turn frequently around
curbs. You can extend the life of your front tires
by remounting them so the outside of the tire
faces inside on the wheel rim.

[MC27300(ALL)01/96]
Replacing the Tires
*
[MC27400(ALL)01/96]
Replace any tires that show wear bands. When
your tire shows a wear band, it has only 1/16
inch (2 mm) of tread left.
*
[MC27500(ALL)01/96]
quarter page art:0060006-A
Wear band
*
[MC27600(ALL)02/96]
Because your vehicle's tires may wear unevenly,
you may need to replace them before a wear
band appears across the entire tread.
*
[MC27700(ALL)03/96]
Your wheels and tires are match-mounted for
improved ride. Before you begin to repair a tire,
mark the wheel and tire so that they are
properly aligned when remounted. This will
ensure that the tires will continue to give you
the same ride level.
