Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem, increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Side Window Demisters
A side window demister outlet is located at each end of
the instrument panel. These non-adjustable outlets direct
air toward the side windows when the system is in the
FLOOR, MIX, or DEFROST mode. The air is directed at
the area of the windows through which you view the
outside mirrors.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
winter months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter — If Equipped
The A/C Filter prevents most dust and pollen from
entering the cabin. The filter acts on air coming from
outside the vehicle and recirculated air within the pas-
senger compartment. Refer to “Maintenance Procedures”
in “Maintaining Your Vehicle” for A/C Air Filter service
information or see your authorized dealer for service.
Refer to “Maintenance Schedules” for filter service
intervals.
312 UNDERSTANDING YOUR INSTRUMENT PANEL

E-85 Usage In Non-Flex Fuel Vehicles
Non-FFV vehicles are compatible with gasoline contain-
ing 10% ethanol (E10). Gasoline with higher ethanol
content may void the vehicle’s warranty.
If a Non-FFV vehicle is inadvertently fueled with E-85
fuel, the engine will have some or all of these symptoms:
•operate in a lean mode
•OBD II “Malfunction Indicator Light” on
•poor engine performance
•poor cold start and cold drivability
•increased risk for fuel system component corrosionTo fix a Non-FFV vehicle inadvertently fueled once with
E-85 perform the following:
•drain the fuel tank (see your authorized dealer)
•change the engine oil and oil filter
•disconnect and reconnect the battery to reset the
engine controller memory
More extensive repairs will be required for prolonged
exposure to E-85 fuel.
MMT In Gasoline
MMT is a manganese containing metallic additive that is
blended into some gasoline to increase octane. Gasoline
blended with MMT provides no performance advantage
beyond gasoline of the same octane number without
MMT. Gasoline blended with MMT reduces spark plug
life and reduces emission system performance in some
vehicles. The manufacturer recommends that gasoline
without MMT be used in your vehicle. The MMT content

MAINTAINING YOUR VEHICLE 457

CAUTION!
Do not use chemical flushes in your engine oil as the
chemicals can damage your engine. Such damage is
not covered by the New Vehicle Limited Warranty.
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 engine. For information on engine oil filler cap
location, refer to “Engine Compartment” in “Maintaining
Your Vehicle” for further information.
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 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
Do not add any supplemental additives, other than leak
detection dyes, to your engine oil. Engine oil is an
engineered product and its performance may be im-
paired 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 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.
464 MAINTAINING YOUR VEHICLE

Engine Oil Filter
The engine oil filter should be replaced with a new filter
at every engine oil change.
NOTE:For best access to the oil filter, a drive on hoist
should be used instead of a chassis hoist (3.7L Only).
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.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
NOTE: Be sure to follow the “dusty or off-road condi-
tions” maintenance interval if applicable.
WARNING!
The air induction system (air cleaner, hoses, etc.) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc.) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc.) removed. Failure to do so can result in
serious personal injury.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be
used to assure most efficient service. MOPAR engine air
cleaner filters are a high quality filter and are
recommended.7
MAINTAINING YOUR VEHICLE 465

WARNING!
•Use 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
Warranty Information Book, located on the DVD,
for further warranty information.
•The 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 hydrofluoro-
carbon (HFC) that is endorsed by the EnvironmentalProtection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by an authorized dealer 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 – If Equipped
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.
WARNING!
Do not remove the A/C Air Filter while the blower is
operating or personal injury may result.
