NOTE:IfANYof these apply to you then change your
engine oil every 3,000 miles (5 000 km) or 3 months,
whichever comes first and follow schedule “B” of the
Maintenance Schedulessection of this manual.
If none of these apply to you, then change your engine oil
at every interval shown on scheduleAof theMainte-
nance Schedulessection of this manual.
NOTE:Under no circumstances should oil change
intervals exceed 6,000 miles (10 000 km) or 6 months
whichever comes first.
CAUTION!
Overfilling or underfilling the crankcase will cause
oil aeration or loss of oil pressure. This could dam-
age your engine.
Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, we only recommend en-
gine oils that are API Certified and meet the requirements
of DaimlerChrysler’s Material Standard MS-6395. Use
Mopar or an equivalent oil meeting the specification
MS-6395.

The proper SAE viscosity grade of engine oil should be
selected based on the following recommendations and be
within the operating temperature shown in the engine oil
viscosity charts.
SAE 10W-30 oil is preferred for use in 3.5L engines within
the operating temperatures shown in the viscosity chart.
SAE 5W-30 engine oil is allowed for use in the 3.5L
engine during cold weather only to improve cold
weather starting.SAE 5W-30 oil is preferred for use in 2.7L engines within
the operating temperatures shown in the viscosity chart.
You are encouraged to use SAE 5W-30 oils to aid in low
temperature starting and for improved fuel economy.
Synthetic Engine Oils
There are a growing number of engine oils being pro-
moted as either synthetic or semi-synthetic. If you choose
to use such a product, useonlythose oils that meet the
American Petroleum Institute (API) and SAE viscosity
standard. Follow the service schedule that describes your
driving type.
Materials Added To Engine Oils
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
engine oil. Engine oil is an engineered product and it’s
performance may be impaired by supplemental addi-
tives.
Disposing of Used Engine Oil
Care should be taken in disposing of used engine oil from
your vehicle. Used oil, 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 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
All of this manufacturer’s engines have a full-flow type
disposable oil filter. Use a filter of this type for replace-
ment. The quality of replacement filters varies consider-
ably. Only high quality filters should be used to assure
most efficient service. Mopar Engine Oil Filters are high
quality oil filters and are recommended.
Drive Belts – Check Condition and Tension
At the mileage shown in the maintenance schedules,
check all drive belts for condition and proper tension.
Improper belt tension can cause belt slippage and failure.
Inspect the drive belts for evidence of cuts, cracks, or
glazing and replace them if there is any sign of damage
which could result in belt failure. If adjustment is re-
quired, adjust the belts according to the specificationsand procedures shown in the Service Manual. See the
Consumer Assistance section for information on ordering
a Service Manual.
Special tools are required to properly measure tension
and to restore belt tension to factory specifications. Also,
check belt routing to make sure there is no interference
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 mileage specified in the appropriate main-
tenance chart. The entire set should be replaced if there is
any malfunction due to a faulty spark plug. Check the
specifications section for the proper type of spark plug
for use in your vehicle.
Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.

WARNING!
Use of a brake fluid that may have a lower initial
boiling point or unidentified as to specification, may
result in sudden brake failure during hard pro-
longed braking. You could have an accident.
Use only brake fluid that has been in a tightly closed
container to avoid contamination from foreign matter.
Do not allow petroleum base fluid to contaminate the
brake fluid as seal damage will result!
Fuel System Hoses
Electronic Fuel Injection high pressure fuel systems are
designed with hoses and clamps which have unique
material characteristics to provide adequate sealing and
resist attack by deteriorated gasoline.You are urged to use only manufacturer specified hoses
and clamps, or their equivalent in material and specifi-
cation, in any fuel system servicing. It is mandatory to
replace all clamps that have been loosened or removed
during service. Care should be taken in installing new
clamps to insure they are properly torqued.
Automatic Transaxle
All front wheel drive vehicles have a transaxle and
differential assembly contained within a single housing.
Selection of Lubricant
It is important that the proper lubricant is used in the
transaxle to assure optimum transaxle performance. Use
only the manufacturer’s recommended transmission
fluid. Refer to the Recommended Fluids, Lubricants and
Genuine Parts section for correct fluid type. It is impor-
tant that the transmission fluid be maintained at the
prescribed level using the recommended fluid.
