Engine Oil Viscosity (SAE Grade) — 3.8 Liter
Engines
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy. Your engine oil filler
cap also shows the recommended engine oil viscosity for
your vehicle.
For information on engine oil filler cap location, refer to
the Engine Compartment illustration in this section.
Lubricants which do not have both, the engine oil certi-
fication mark and the correct SAE viscosity grade num-
ber should not be used.
Synthetic Engine Oils
There are a number of engine oils being promoted as
either synthetic or semi-synthetic. If you chose to use
such a product, useonlythose oils that are AmericanPetroleum Institute (API) Certified and have the recom-
mended SAE viscosity grade. Follow the maintenance
schedule that describes your driving type.
Materials Added to Engine Oil
The manufacture strongly recommends against the addi-
tion of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and
it’s performance may be impaired by supplemental ad-
ditives.
Disposing of Used Engine Oil And Oil Filters
Care should be taken in disposing of used engine oil and
oil filters from your vehicle. Used oil and oil filters,
indiscriminately discarded, can present a problem to the
environment. Contact your dealer, service station, or
governmental agency for advice on how and where used
oil and oil filters can be safely discarded in your area.

Engine Oil Filter
The engine oil filter should be replaced at every engine
oil change.
Engine Oil Filter Selection
This manufacture’s engines have a full-flow type oil filter.
Use a filter of this type for replacement. The quality of
replacement filters varies considerably. Only high quality
filters should be used to assure most efficient service.
Mopar Engine Oil Filters are a high quality oil filter and
are recommended.
Drive Belts — Check Condition and Tension
At the mileage indicated in the maintenance schedule, all
belts should be checked for condition and proper tension.
Improper belt tension can cause belt slippage and failure.
Belts should be inspected for evidence of cuts, cracks, or
glazing, and replaced if there is indication of damage
which could result in belt failure. Low generator belt
tension can cause battery failure.Also check belt routing to make sure there is no interfer-
ence between the belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Malfunctioning spark plugs can damage the cata-
lytic converter. For proper type of replacement spark
plugs, refer to the “Vehicle Emission Control Informa-
tion” label in the engine compartment.
Engine Air Cleaner Filter
Under normal driving conditions, replace the air filter at
the intervals shown on Schedule “A”. If, however, you
drive the vehicle frequently under dusty or severe con-
ditions, the filter element should be inspected periodi-
cally and replaced if necessary at the intervals shown on
Schedule “B”.

Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydrofluorocar-
bon (HFC) that is endorsed by the Environmental Pro-
tection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by dealers or other service facilities
using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, or Refrigerants.
A/C Air Filter
The filter access door is located under the instrument
panel on the passenger side. To replace the filter slide the
lock toward the rear of the vehicle (unlock position).
Remove the access door and pull the filter downward.
When installing a new filter, ensure its proper orienta-
tion. Align the black arrow on the bottom of the filterframe with the direction of airflow (away from the
blower motor and towards the center of the car).
Refer to the “Maintenance Schedules” section of this
manual for the recommended air conditioning filter
replacement intervals.
Power Steering — Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.
