INTRODUCTION
Chrysler Corporation has compiled recommended
lubrication and maintenance schedules and proce-
dures to help reduce premature wear or failure over
a broad range of operating conditions. When select-
ing the proper maintenance schedule, the climate
and operating conditions must be considered. A vehi-
cle subjected to severe usage requires more frequent
service than a vehicle used for general transporta-
tion.
PARTS AND LUBRICANT RECOMMENDATIONS
When service is required, Chrysler Corporation rec-
ommends that only Mopartbrand parts, lubricants
and chemicals be used. Mopar provides the best en-
gineered products for servicing Chrysler Corporation
vehicles.
SEVERE SERVICE
If a vehicle is operated under any of the following
conditions, it is considered severe service.
•Extremely dusty areas.
•50% or more of vehicle operation in 32°C (90°F) or
higher temperatures.
•Prolonged idling (such as, vehicle operation in stop
and go traffic).
•Frequent short running periods. Not allowing en-
gine to warm to operating temperatures.
•Police or taxi usage.
FUEL USAGE
All Chrysler Corporation engines require the use of
unleaded fuel to reduce exhaust emissions. See En-
gine section of this group and Group 14, Fuel for fuel
recommendations.
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)
•National Lubricating Grease Institute (NLGI)
ENGINE OIL
SAE GRADE RATING INDICATES ENGINE OIL VISCOSITY
•SAE 30 = single grade engine oil.
•SAE 5W-30 = multiple grade engine oil.
API QUALITY CLASSIFICATION.
•SG service engine oil is a high quality crankcase
lubricant designed for use in all naturally aspirated
engines.
•SG/CD service engine oil is a high performance
crankcase lubricant designed for use in all gasoline
or diesel engines.
GEAR LUBRICANTS
SAE ratings also apply to multiple grade gear lu-
bricants. In addition, API classification defines the
lubricants usage.
LUBRICATION AND MAINTENANCE 0 - 1

LUBRICANTS AND GREASES
Lubricating grease is rated for quality and usage
by the NLGI. All approved products have the NLGI
symbol on the label.
At the bottom NLGI symbol is the usage and qual-
ity identification letters. Wheel bearing lubricant is
identified by the letter ‘‘G’’. Chassis lubricant is iden-
tified by the letter ‘‘L’’. The letter following the us-
age letter indicates the quality of the lubricant. The
following symbols indicate the highest quality.
PARTS REQUIRING NO LUBRICATION
Many components on a Chrysler Corporation vehi-
cle require no periodic maintenance. Some compo-
nents are sealed and permanently lubricated. Rubber
bushings can deteriorate or limit damping ability if
lubricated. The following list of components require
no lubrication:
•Air Pump
•Generator Bushings
•Drive Belts
•Drive Belt Idler/Tensioner Pulley
•Wheel Bearings
•Rubber Bushings
•Starter Bearings/Bushings
•Suspension Strut Bearings
•Throttle Control Cable
•Throttle Linkage
•Water Pump Bearings

spect 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, turn off all accessories, place gear selector in
park or neutral, set park brake or equivalent and op-
erate engine at 1200 rpm.
(3) On disabled vehicle, place gear selector in park
or neutral and set park brake or equivalent. Turn
OFF all accessories (Keyless Entry system must be
turned OFF manually).
(4) Connect jumper cables to booster battery. RED
clamp to positive terminal (+). BLACK clamp to
negative terminal (-). DO NOT allow clamps at oppo-
site end of cables to touch, electrical arc will result
(Fig. 1). 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).
CAUTION: Do not crank starter motor on disabled
vehicle for more than 15 seconds, starter will over-
heat and could fail.
(6) 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-
onds, stop cranking engine and allow starter to cool
(15 min.), before cranking again.

TOWING RECOMMENDATIONS
RECOMMENDED TOWING EQUIPMENT
To avoid damage to bumper fascia and air dams
use of a wheel lift or flat bed towing device (Fig. 3) is
recommended. When using a wheel lift towing de-
vice, be sure the rear end of disabled vehicle has at
least 100 mm (4 in.) ground clearance. If minimum
ground clearance cannot be reached, use a towing
dolly. If a flat bed device is used, the approach angle
should not exceed 15 degrees.
GROUND CLEARANCE
CAUTION: If vehicle is towed with wheels removed,
install lug nuts to retain brake drums or rotors.
A towed vehicle should be raised until lifted wheels
are a minimum 100 mm (4 in) from the ground. Be
sure there is adequate ground clearance at the oppo-
site end of the vehicle, especially when towing over
rough terrain or steep rises in the road. If necessary,
remove the wheels from the lifted end of the vehicle
and lower the vehicle closer to the ground, to in-
crease the ground clearance at the opposite end of
the vehicle. Install lug nuts on wheel attaching studs
to retain braking discs.
SAFETY PRECAUTIONS
The following safety precautions must be consid-
ered when preparing for and during a vehicle towing
operation:
•Do NOT tow vehicle with front wheels on the
ground. The transaxle can be damaged.
•Secure loose and protruding parts from a disabled
vehicle.
•Always use a safety chain system that is indepen-
dent of the lifting and towing equipment.
•Do not allow any of the towing equipment to con-
tact the fuel tank of the vehicle being towed.
•Do not go under the vehicle while it is lifted by
the towing equipment.
•Do not allow passengers to ride in a vehicle being
towed.
•Always observe all state and local laws pertaining
to warning signals, night illumination,speed, etc.
•Do not attempt a towing operation that could jeop-
ardize the operator, bystanders or other motorists.
•Do not exceed a towing speed of 48 km/h (30mph).
•Avoid towing distances of more than 24 km
(15miles), whenever possible.
•Never attach tow chains or a tow sling to the
bumper, steering linkage, or constant velocity joints.
TIE DOWN LOCATIONS FOR FLAT BED
TOWING
There are three reinforced elongated holes on each
side of the vehicle designed to serve as hold down lo-
cations. These locations can safely hold the vehicle to
the towing device using T or R-hooks.
•Bottom of the front frame rail forward of the en-
gine cradle.
•Bottom of the forward torque box between the
front frame rail and the rocker panel.
•Bottom of the rearward torque box forward of the
rear wheel.
FRONT TOWING PROCEDURES
CAUTION: Do Not tow vehicle from the front with
sling type towing device. Damage to bumper fascia
will result.
Always tow vehicle with front wheels off the
ground as shown (Fig. 4).
Use a flat bed towing device when wheel lift tow-
ing device is not available.
