CAUTION!
DO NOT use gasoline containing Methanol. Use of
these blends may result in starting and drivability
problems and may damage critical fuel system com-
ponents.
Problems that result from using methanol/gasoline
blends are not the responsibility of the manufacturer.
While MTBE is an oxygenate made from Methanol, it
does not have the negative effects of Methanol.
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 corrosion
To 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

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.
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 the
environment. 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 interval.

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. MOPARengine air
cleaner filters are a high quality filter and are
recommended.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required.
WARNING!
•Battery fluid is a corrosive acid solution and can
burn or even blind you. Do not allow battery fluid
to contact your eyes, skin or clothing. Do not lean
over a battery when attaching clamps. If acid
splashes in eyes or on skin, flush the area imme-
diately with large amounts of water.
•Battery gas is flammable and explosive. Keep
flame or sparks away from the battery. Do not use
a booster battery or any other booster source with
an output greater than 12 Volts. Do not allow cable
clamps to touch each other.

Automatic Transmission
Selection of Lubricant
It is important that the proper lubricant is used in the
transmission to assure optimum transmission perfor-
mance. Use only the manufacturer’s recommended trans-
mission fluid. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for correct fluid type. It is important
that the transmission fluid be maintained at the pre-
scribed level using the recommended fluid.
CAUTION!
Using a transmission fluid other than the manufac-
turer’s recommended fluid may cause deterioration
in transmission shift quality and/or torque converter
shudder. Using a transmission fluid other than the
manufacturer’s recommended fluid will result in
more frequent fluid and filter changes. Refer to
“Fluids, Lubricants, and Genuine Parts” in this sec-
tion for correct fluid type.
Special Additives
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. In addition, avoid using transmission sealers as
they may adversely affect seals.
