The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the ªEngine Com-
partmentº illustration in this section.
NOTE:Vehicles equipped with a 5.7L engine must use
SAE 5W-20 oil. Failure to do so may result in improper
operation of the Multiple Displacement System (MDS).
Refer to ªMulti Displacement Systemº under ªStarting
and Operatingº for more details.
Lubricants, which do not have both, the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.
Engine Oil Viscosity (SAE Grade) Ð 3.5L Engine
SAE 10W-30 engine oil is preferred for use in 3.5L
Engines for all operating temperatures.The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to the ªEngine Com-
partmentº illustration in this section.
Lubricants, which do not have both, the engine oil
certification mark and the correct SAE viscosity grade
number should not be used.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added to Engine Oil
The manufacturer strongly recommends against the ad-
dition of any additives (other than leak detection dyes) to
the engine oil. Engine oil is an engineered product and its
performance may be impaired by supplemental addi-
tives.

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 manufacturer'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. MopartEngine Oil Filters are a high quality oil
filter and are recommended.
Drive Belts Ð Check Condition and Tension
Belt tension is controlled by means of an automatic
tensioner. Therefore, no belt tension adjustments are
required. However, belt and belt tensioner condition
should be inspected periodically and replaced if re-
quired. Improper belt tension can cause belt slippage and
failure. Low generator belt tension can cause battery
failure.
Inspect belts for evidence of cuts, cracks, glazing, or
frayed cords and replaced if there is indication of dam-
age, which could result in belt failure. Also, check belt
routing to make sure there is no interference between the
belts and other engine components. See your authorized
dealer for service.

WARNING!
²Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning system. Some unapproved refrigerants are
flammable and can explode, injuring you. Other
unapproved refrigerants or lubricants can cause
the system to fail, requiring costly repairs. Refer to
Section 3 of the Warranty Information book for
further warranty information.
²The air conditioning system contains refrigerant
under high pressure. To avoid risk of personal
injury or damage to the system, adding refrigerant
or any repair requiring lines to be disconnected
should be done by an experienced technician.
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, and Refrigerants.
A/C Air Filter Ð If Equipped
The filter is located in the fresh air inlet under the hood,
behind a removable panel in the cowl on the passenger
side of the vehicle, next to the windshield wipers. When
installing a new filter, ensure its proper orientation. To
replace the filter remove the access door in the cowl
screen by pressing the retaining clips. Slide the lid on the
filter adapter forward and down and remove used filter.
