Regular cleaning of the inside of the windows with a
non-filming cleaning solution (vinegar and water works
very well) will help prevent contaminates (cigarette
smoke, perfumes, etc.) from sticking to the windows.
Contaminates increase the rate of window fogging.
Summer Operation
Air conditioned vehicles must be protected with a high
quality antifreeze coolant, during summer, to provide
proper corrosion protection and to raise the boiling point
of the coolant for protection against overheating. A 50%
concentration is recommended. Refer to Fluids, Lubri-
cants, and Genuine Parts in Section 7 for the proper
coolant type.
When using the air conditioner in extremely heavy traffic, in
hot weather, especially when towing a trailer, additional
engine cooling may be required. If this situation is encoun-
tered, operate the transmission in a lower gear to increase
engine RPM, coolant flow and fan speed. When stopped inheavy traffic, it may be necessary to shift into NEUTRAL
and depress the accelerator slightly for fast idle operation to
increase coolant flow and fan speed.
Your air conditioning system is also equipped with an
automatic recirculation system. When the system senses
a heavy load or high heat conditions, it may use partial
Recirculation A/C mode to provide additional comfort.
Winter Operation
When operating the system during the winter months, make
sure the air intake, located directly in front of the wind-
shield, is free of ice, slush, snow, or other obstructions.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will ensure adequate
system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
284 UNDERSTANDING YOUR INSTRUMENT PANEL

For best results, a refueling pattern that avoids alternat-
ing between E-85 and unleaded gasoline is recom-
mended.
When you do switch fuel types it is recommended that:
•you do not add less than 5 gal (19 L) when refueling
•you drive the vehicle immediately after refueling for at
least 5 mi (8 km)
Observing these precautions will avoid possible hard
starting and/or significant deterioration in drivability
during warm up.
NOTE:Use seasonally adjusted E-85 fuel (ASTM
D5798). With non-seasonally adjusted E-85 fuel, you may
experience hard starting and rough idle following start
up even if the above recommendations are followed,
especially when the ambient temperature is below 32°F
(0°C).
Selection Of Engine Oil For Flexible Fuel Vehicles
(E-85) and Gasoline Vehicles
Whether operating the vehicle on an E-85 ethanol fuel or
unleaded gasoline, the engine oil requirements are the
same. Refer to “Maintenance Procedures” in Section 7 of
this manual for the proper quality and viscosity engine
oil.
Starting
The characteristics of E-85 fuel make it unsuitable for use
when ambient temperatures fall below 0°F (-18°C). In the
range of 0° to 32°F (-18° to 0°C), you may experience an
increase in the time it takes for your engine to start, and
a deterioration in drivability (sags and/or hesitations)
until the engine is fully warmed up.
Cruising Range
Because E-85 fuel contains less energy per gallon/liter
than gasoline, you will experience an increase in fuel
374 STARTING AND OPERATING

Engine Oil Selection
For best performance and maximum protection for all
engines under all types of operating conditions, the
manufacturer recommends engine oils that are API Cer-
tified and meet the requirements of Chrysler Material
Standard MS-6395.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.
Engine Oil Viscosity
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 vehicle. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” 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 “Multi-Displacement System” in Section 5 for
more details.
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
You may use synthetic engine oils if the recommended oil
quality requirements are met, and the recommended
maintenance intervals for oil and filter changes are
followed.
Materials Added to Engine Oils
The manufacturerstrongly recommendsagainst 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
additives.
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 theenvironment. Contact your local authorized dealer, ser-
vice 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 with a new filter
at every oil change.
Engine Oil Filter Selection
The 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 effi-
cient service. MOPARengine oil filters are high-quality
oil filters and are recommended.
Engine Air Cleaner Filter
Refer to the Maintenance Schedule in Section 8 for the
proper maintenance intervals.

•Use MOPARTouch Up Paint on scratches or chips as
soon as possible. Your authorized dealer has touch up
paint to match the color of your vehicle.
Wheel and Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome-plated wheels should be cleaned regularly with a
mild soap and water to prevent corrosion. To remove
heavy soil, use MOPARWheel Cleaner or select a
nonabrasive, non-acidic cleaner. Do not use scouring
pads, steel wool, a bristle brush or metal polishes. Only
MOPARcleaners are recommended. Do not use oven
cleaner. Avoid automatic car washes that use acidic
solutions or harsh brushes that may damage the wheels’
protective finish.

MOPARSpot & Stain Remover, if absolutely necessary.
Do not use harsh cleaners or Armorall. Use MOPAR
Total Clean to clean vinyl upholstery.
Leather Seat Care And Cleaning
MOPARTotal Clean is specifically recommended for
leather upholstery.
Your leather upholstery can be best preserved by regular
cleaning with a damp soft cloth. Small particles of dirt
can act as an abrasive and damage the leather upholstery
and should be removed promptly with a damp cloth.
Stubborn soils can be removed easily with a soft cloth
and MOPARTotal Clean. Care should be taken to avoid
soaking your leather upholstery with any liquid. Please
do not use polishes, oils, cleaning fluids, solvents, deter-
gents, or ammonia-based cleaners to clean your leather
upholstery. Application of a leather conditioner is not
required to maintain the original condition.
WARNING!
Do not use volatile solvents for cleaning purposes.
Many are potentially flammable, and if used in
closed areas, they may cause respiratory harm.
Cleaning Headlights
Your vehicle has plastic headlights that are lighter and
less susceptible to stone breakage than glass headlights.
Plastic is not as scratch-resistant as glass and therefore
different lens cleaning procedures must be followed.
To minimize the possibility of scratching the lenses and
reducing light output, avoid wiping with a dry cloth. To
remove road dirt, wash with a mild soap solution fol-
lowed by rinsing.
Do not use abrasive cleaning components, solvents, steel
wool or other aggressive material to clean the lenses.
