The graphic symbols illustrated in the following
chart (Fig. 3) are used to identify various instrument
controls. The symbols correspond to the controls and
displays that are located on the instrument panel.
FASTENER IDENTIFICATION
FASTENER IDENTIFICATION
THREAD IDENTIFICATION
SAE and metric bolt/nut threads are not the same.
The difference is described in the Thread Notation
chart (Fig. 4).
GRADE/CLASS IDENTIFICATION
The SAE bolt strength grades range from grade 2
to grade 8. The higher the grade number, the greater
the bolt strength. Identification is determined by the
line marks on the top of each bolt head. The actual
bolt strength grade corresponds to the number of line
marks plus 2. The most commonly used metric bolt
strength classes are 9.8 and 12.9. The metric
strength class identification number is imprinted on
the head of the bolt. The higher the class number,
the greater the bolt strength. Some metric nuts are
imprinted with a single-digit strength class on the
nut face. Refer to the Fastener Identification and
Fastener Strength Charts.

METRIC SYSTEM
WARNING: USE OF AN INCORRECT FASTENER
MAY RESULT IN COMPONENT DAMAGE OR PER-
SONAL INJURY.
Figure art, specifications and torque references in
this Service Manual are identified in metric and SAE
format.
During any maintenance or repair procedures, it is
important to salvage metric fasteners (nuts, bolts,
etc.) for reassembly. If the fastener is not salvage-
able, a fastener of equivalent specification should be
used.
The metric system is based on quantities of one,
ten, one hundred, one thousand and one million (Fig.
5).The following chart will assist in converting metric
units to equivalent English and SAE units, or vise
versa.
Refer to the Conversion Chart to convert torque
values listed in metric Newton- meters (N·m). Also,
use the chart to convert between millimeters (mm)
and inches (in.)
TORQUE REFERENCES
Individual Torque Charts appear at the end of
many Groups. Refer to the Standard Torque Specifi-
cations Chart for torque references not listed in the
individual torque charts.

INTRODUCTION
Service and maintenance procedures for compo-
nents and systems listed in Schedule—A or B can be
found by using the Group Tab Locator index at the
front of this manual. If it is not clear which group
contains the information needed, refer to the index at
the back of this manual.
There are two maintenance schedules that show
proper service based on the conditions that the vehi-
cle is subjected to.
Schedule— A, lists scheduled maintenance to be
performed when the vehicle is used for general trans-
portation.
Schedule— B, lists maintenance intervals for vehi-
cles that are operated under the conditions listed at
the beginning of the Maintenance Schedule section.
Use the schedule that best describes your driving
conditions.
Where time and mileage are listed, follow the
interval that occurs first.
PARTS AND LUBRICANT RECOMMENDATIONS
When service is required, Chrysler Corporation
recommends that only Mopartbrand parts, lubri-
cants and chemicals be used. Mopar provides the
best engineered products for servicing Chrysler Cor-
poration vehicles.
INTERNATIONAL SYMBOLS
Chrysler Corporation uses international symbols to
identify engine compartment lubricant and fluid
inspection and fill locations (Fig. 1).
CLASSIFICATION OF LUBRICANTS
Only lubricants that are endorsed by the following
organization should be used to service a Chrysler
Corporation vehicle.
•Society of Automotive Engineers (SAE)
•American Petroleum Institute (API) (Fig. 2)
•National Lubricating Grease Institute (NLGI)

ENGINE OIL
SAE GRADE RATING INDICATES ENGINE OIL VISCOSITY
An SAE viscosity grade is used to specify the vis-
cosity of engine oil. SAE 30 specifies a single viscos-
ity engine oil. Engine oils also have multiple
viscosities. These are specified with a dual SAE vis-
cosity grade which indicates the cold-to-hot tempera-
ture viscosity range.
•SAE 30 = single grade engine oil.
•SAE 10W-30 = multiple grade engine oil.
API QUALITY CLASSIFICATION
The API Service Grade specifies the type of perfor-
mance the engine oil is intended to provide. The API
Service Grade specifications also apply to energy con-
serving engine oils.
Use engine oils that are API Service Certified.
5W-30 and 10W-30 MOPAR engine oils conform to
specifications.
Refer to Group 9, Engine for engine oil specifica-
tion.
GEAR LUBRICANTS
SAE ratings also apply to multiple grade gear
lubricants. In addition, API classification defines the
lubricants usage.
LUBRICANTS AND GREASES
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol (Fig. 3) on the label. At the bottom NLGI
symbol is the usage and quality identification letters.
Wheel bearing lubricant is identified by the letter
“G”. Chassis lubricant is identified by the latter “L”.
The letter following the usage letter indicates the
quality of the lubricant. The following symbols indi-
cate the highest quality.

SERVICE PROCEDURES
JUMP STARTING PROCEDURE
WARNING: REVIEW ALL SAFETY PRECAUTIONS
AND WARNINGS IN GROUP 8A, BATTERY/STARTING/
CHARGING SYSTEMS DIAGNOSTICS. DO NOT JUMP
START A FROZEN BATTERY, PERSONAL INJURY CAN
RESULT. DO NOT JUMP START WHEN MAINTENANCE
FREE BATTERY INDICATOR DOT IS YELLOW OR
BRIGHT COLOR. DO NOT JUMP START A VEHICLE
WHEN THE BATTERY FLUID IS BELOW THE TOP OF
LEAD PLATES. DO NOT ALLOW JUMPER CABLE
CLAMPS TO TOUCH EACH OTHER WHEN CON-
NECTED TO A BOOSTER SOURCE. DO NOT USE
OPEN FLAME NEAR BATTERY. REMOVE METALLIC
JEWELRY WORN ON HANDS OR WRISTS TO AVOID
INJURY BY ACCIDENTAL ARCING OF BATTERY CUR-
RENT. WHEN USING A HIGH OUTPUT BOOSTING
DEVICE, DO NOT ALLOW BATTERY VOLTAGE TO
EXCEED 16 VOLTS. REFER TO INSTRUCTIONS PRO-
VIDED WITH DEVICE BEING USED.
CAUTION: When using another vehicle as a
booster, do not allow vehicles to touch. Electrical
systems can be damaged on either vehicle.
TO JUMP START A DISABLED VEHICLE:
(1) Raise hood on disabled vehicle and visually
inspect engine compartment for:
•Battery cable clamp condition, clean if necessary.
•Frozen battery.
•Yellow or bright color test indicator, if equipped.
•Low battery fluid level.
•Generator drive belt condition and tension.
•Fuel fumes or leakage, correct if necessary.
CAUTION: If the cause of starting problem on dis-
abled vehicle is severe, damage to booster vehicle
charging system can result.
(2)
When using another vehicle as a booster source,
park the booster vehicle within cable reach. Turn off all
accessories, set the parking brake, place the automatic
transmission in PARK or the manual transmission in
NEUTRAL and turn the ignition OFF.
(3) On disabled vehicle, place gear selector in park
or neutral and set park brake. Turn off all accesso-
ries.
(4) Connect jumper cables to booster battery. RED
clamp to positive terminal (+). BLACK clamp to neg-
ative terminal (-). DO NOT allow clamps at opposite
end of cables to touch, electrical arc will result.
Review all warnings in this procedure.
(5) On disabled vehicle, connect RED jumper cable
clamp to positive (+) terminal. Connect BLACK
jumper cable clamp to engine ground as close to the
ground cable attaching point as possible (Fig. 1).
(6) Start the engine in the vehicle which has the
booster battery, let the engine idle a few minutes,
then start the engine in the vehicle with the dis-
charged battery.
CAUTION: Do not crank starter motor on disabled
vehicle for more than 15 seconds, starter will over-
heat and could fail.
(7) Allow battery in disabled vehicle to charge to
at least 12.4 volts (75% charge) before attempting to
start engine. If engine does not start within 15 sec-
