CONTENTSThe preceding page contains GROUP INDEX which
lists the group title and group number.
PAGE NUMBERS
All page numbers consist of two sets of digits
separated by a dash. The digits preceding the dash
identify the

ing the dash represent the consecutive page num-
ber within the group. The page numbers can be
found on the top left or right of each page.
TEXT
Unless otherwise specified, each service procedurecovers all models. Procedures covering specific
models are identified by the model codes, or similar
designation (engine type, transaxle type, etc.). A
description of these designations is covered in this
unit under “VEHICLE IDENTIFICATION”.
TROUBLESHOOTING
Troubleshootings are classified into master trouble-
shooting and group troubleshooting and located as
follows:
The master troubleshooting is prepared when the
trouble symptom relates to two or more groups and
given in MASTER TROUBLESHOOTING.
The group troubleshooting guide is prepared for
causes of problems related to that individual group
only; a troubleshooting guide is prepared for each
appropriate group.LIMIT

: 928mm (36.5 in.)
: 998mm (39.3 in.)
IRearISAFETY PRECAUTIONS
The following precautions should be taken when
towin the
vehicle.
1.DO NOT LIFT OR TOW THE VEHICLE BY ATTACHING TOOR WRAPPING AROUND THE BUMPER.
2. Any loose or protruding parts of damaged vehicle such as
hoods, doors, fenders, trim, etc., should be secured prior tomoving the vehicle.
3.Operator should refrain from going under a vehicle while it
is lifted by the towing equipment, unless the vehicle in
adequately supported by satefy stands.
4. Never allow passengers to ride in a towed vehicle.
5. State and local rules and regulations must be followed
when towing a vehicle.
Refer to the section “Special Handling Instructions for AWD
Models”.
HOISTING
POST TYPESpecial care should be taken when raising the vehicle on a
frame contact type hoist. The hoist must be equipped with the
proper adapters in order to support the vehicle at the proper
locations.Caution
When service procedures require removing rear sutpen-
sion, fuel tank, spare tire and lift gate, place addmonal
weight on rear end of vehicle or anchor vehicle to hoist to
prevent tipping of center of gravity changes.
FLOOR JACK
The usual type of floor jack is used at the following locations.
Front:
Under the mid point of centermember
Under the mid point of crossmember
Rear:
Under the jack up bracket of rear floor pan
Under the rear differential
Cautions
1. Never use a jack at the lateral rod or rear suspension
assembly.

2.In order to prevent scarring the centermember or crossmember
, place a piece of cloth on the
jack’s contact surface (to prevent corrosion caused by
damage to the coating).
3. A floor jack must never be used on any part of the
underbody.
4.Do not attempt to raise one entire side of the vehicle byplacing a jack midway between front and rear wheels.
This practice may result in permanent damage to the
body.

o-2LUBRICATION AND MAINTENANCE - General Information
GENERAL INFORMATIONNGQPA--Maintenance and lubrication service recommenda-
tions have been compiled to provide maximum
protection for the vehicle owner’s investment
against all reasonable types of driving conditions.
Since these conditions vary with the individual
vehicle owner’s driving habits, the area in which the
vehicle is operated and the type of driving to which
the vehicle is subjected, it is necessary to prescribe
lubrication and maintenance service on a time
frequency as well as mileage interval basis.
Oils, lubricants and greases are classified and
graded according to standards recommended by theSociety of Automotive Engineers (SAE), the Amer-
ican Petroleum Institute (API) and the National
Lubricating Grease Institute
(NLGI).MAINTENANCE SCHEDULES
Information for service maintenance is provided
under “SCHEDULED MAINTENANCE TABLE”.
Three schedules are provided; one for “Required
Maintenance”, one for “General Maintenance” and
one for “Severe Usage Service”.
Item numbers in the “SCHEDULED MAINTE-
NANCE TABLE” correspond to the item numbers in
the “MAINTENANCE SERVICE” section.
SEVERE SERVICEVehicles operating under severe service conditions
will require more frequent service.
Component service information is included in
appropriate units for vehicles operating under one ormore of the following conditions:
1.Trailer towing or police, taxi, or commercial type
operation2. Operation of Vehicle
(1) Short-trip operation at freezing temperature
(engine not thoroughly warmed up)
(2) More than 50% operation in heavy city
traffic during hot weather above
32°C (90°F)(3) Extensive idling
(4) Driving in sandy areas
(5) Driving in salty areas
(6) Driving in dusty conditions
ENGINE OIL
The SAE grade number indicates the viscosity of
engine oils, for example, SAE 30, which is a single
grade oil. Engine oils are also identified by a dual
number, for example, SAE
lOW-30, which indicates
a multigrade oil.
The API classification system defines oil perform-
ance in terms of engine usage. Only engine oil
designed “For Service SG” or “For Service
SGKD”,when available, should be used. These oils contain
sufficient chemical additives to provide maximum
engine protection. Both the SAE grade and the API
designation can be found on the container.Caution
Test results submitted to EPA have shown thatlaboratory animals develop skin cancer after
prolonged contact with used engine oil. Accor-
dingly, the potential exists for humans
to de-
velop a number of skin disorders, including
cancer, from such exposure to used engine oil.
Care should be’ taken, therefore, when changingengine oil, to minimize the amount and length of
exposure time to used engine
pi! on your skin.
Protective clothing and gloves, that cannot be
penetrated by oil, should be worn. The skin
should be thoroughly washed with soap and
water, or use waterless hand cleaner, to removeany used engine oil. Do not use gasoline,
thinners, or solvents.
GEAR LUBRICANTSThe SAE grade number also indicates the viscosity
of Multi-Purpose Gear Lubricants.
The API classfication system defines gear lubricants
in terms of usage. Typically gear lubricants conform-ing to API
GL-4 or GL-5 with a viscosity of SAE
75W-85W are recommended for manual transaxle.
LUBRICANTS
- GREASES
Semi-solid lubricants, bear the NLGI designation andare further classified as grades 0, 1, 2, 3 etc.
Whenever “Chassis Lubricant” is specified, Multi-
Purpose Grease,
NLGI grade 2 should be used.
MOPAR Multi-Mileage Lubricant, P&t Number
2525035 or equivalent, meets these requirement
and is recommended.
FUEL USAGE STATEMENT
Use gasolines having a minimum anti-knock index
(Octane Value) of 87,
(R + M)/2. This designation is
comparable to a Research Octane Number of 91.
Unleaded gasolines only must be used in vehicles
equipped with catalyst emission control systems.
All vehicles, so equipped, have labels located on the
instrument panel and on the back of fuel filler lid that
state, “UNLEADED GASOLINE ONLY”. These vehi-
cles also have fuel filler tubes especially designed toaccept the smaller diameter unleaded gasoline
dispensing nozzles only.
MATERIALS ADDED
TO FUELIndiscriminate use of fuel system cleanng agents
should be avoided. Many of these materials in-
tended for gum and varnish removal may contain
highly active solvents or similar ingredients that can
be harmful to gasket and diaphragm materials usedin fuel system component parts.
