Engine Oil Viscosity (SAE Grade) — 2.4L and 2.7L
Engines
SAE 5W-20 engine oil is recommended for all operating
temperatures. This engine oil improves low temperature
starting and vehicle fuel economy.
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 “Engine Com-
partment” illustration in this section.
Lubricants that do not have both, the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
Engine Oil Viscosity (SAE Grade) — 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 “Engine Com-
partment” illustration in this section.
Lubricants that do not have both, the engine oil certifi-
cation 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 authorized 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 dispos-
able 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. MoparEngine Oil Filters are high quality oil
filters and are recommended.
Drive Belts — 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 replace if there is indication of damage
that could result in belt failure. Also, check belt routing to
make sure there is no interference between the belts and
other engine components. Refer to the Maintenance
Schedule in Section 8 for specified service intervals. See
your authorized dealer for service.

Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by authorized dealers or other
service facilities using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system
sealers, stop leak products, seal conditioners, compressor
oil, and refrigerants.
A/C Air Filter — If Equipped
Refer to the Maintenance Schedule in Section 8 for A/C
air filter service intervals.
WARNING!
Do not remove the A/C air filter while the blower is
operating or personal injury may result.
The A/C air filter is located in the fresh air inlet behind
the glove box. Perform the following steps to replace the
filter:
1. Open the glove box and remove all contents.
2. Push the retaining tab on each side of the glove box
inward while gently pulling the glove box door outward
until both tabs clear the door opening in the instrument
panel.
