been certified by the American Petro -
leum Institute (API). The manufac -
turer only recommends API Certified
engine oils.
This symbol certifies 0W-20, 5W-20, 0W-30,
5W-30 and 10W-30 engine oils.
Engine Oil Viscosity (SAE Grade) — 3.6L Engine
Mopar SAE 5W-20 engine oil approved to FCA
Material Standard MS-6395 such as Pennzoil,
Shell Helix Ultra or equivalent 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 recom -
mended engine oil viscosity for your engine. For
information on engine oil filler cap location,
refer to the “Engine Compartment” illustration
in this section. NOTE:
Mopar SAE 5W-30 engine oil approved to FCA
Material Standard MS-6395 such as Pennzoil,
Shell Helix Ultra or equivalent may be used
when SAE 5W-20 engine oil meeting MS-6395
is not available.
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
recommended oil quality requirements are met,
and the recommended maintenance intervals
for oil and filter changes are followed.
Synthetic engine oils which do not have both the
engine oil certification mark and the correct SAE
viscosity grade number should not be used.
Materials Added To Engine Oil
The manufacturer strongly recommends
against the addition 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
an authorized dealer, service station or govern
-
mental 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 engine oil change.
Engine Oil Filter Selection
This manufacturer's engines have a full-flow
type disposable 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 ensure most efficient
service. Mopar engine oil filters are high quality
oil filters and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Plan” in this section
for the proper maintenance intervals.

Windshield Wiper Blades
Clean the rubber edges of the wiper blades and
the windshield periodically with a sponge or soft
cloth and a mild nonabrasive cleaner. This will
remove accumulations of salt or road film.
Operation of the wipers on dry glass for long
periods may cause deterioration of the wiper
blades. Always use washer fluid when using the
wipers to remove salt or dirt from a dry wind -
shield.
Avoid using the wiper blades to remove frost or
ice from the windshield. Keep the blade rubber
out of contact with petroleum products such as
engine oil, gasoline, etc.
NOTE:
Life expectancy of wiper blades varies
depending on geographical area and frequency
of use. Poor performance of blades may be
present with chattering, marks, water lines or
wet spots. If any of these conditions are
present, clean the wiper blades or replace as
necessary.
Exhaust System
The best protection against carbon monoxide
entry into the vehicle body is a properly main -
tained engine exhaust system.
If you notice a change in the sound of the
exhaust system; or if the exhaust fumes can be
detected inside the vehicle; or when the under -
side or rear of the vehicle is damaged; have an
authorized technician inspect the complete
exhaust system and adjacent body areas for
broken, damaged, deteriorated, or misposi -
tioned parts. Open seams or loose connections
could permit exhaust fumes to seep into the
passenger compartment. In addition, have the
exhaust system inspected each time the vehicle
is raised for lubrication or oil change. Replace
as required.
WARNING!
Exhaust gases can injure or kill. They
contain carbon monoxide (CO), which is
colorless and odorless. Breathing it can
make you unconscious and can eventually
poison you. To avoid breathing CO, refer to
“Safety Tips” in “Safety” for further informa -
tion.
A hot exhaust system can start a fire if you
park over materials that can burn. Such
materials might be grass or leaves coming
into contact with your exhaust system. Do
not park or operate your vehicle in areas
where your exhaust system can contact
anything that can burn.
CAUTION!
The catalytic converter requires the use of
unleaded fuel only. Leaded gasoline will
destroy the effectiveness of the catalyst as
an emissions control device and may seri -
ously reduce engine performance and
cause serious damage to the engine.
Damage to the catalytic converter can
result if your vehicle is not kept in proper
operating condition. In the event of engine
malfunction, particularly involving engine
misfire or other apparent loss of perfor -
mance, have your vehicle serviced
promptly. Continued operation of your
vehicle with a severe malfunction could
cause the converter to overheat, resulting
in possible damage to the converter and
vehicle.

Tires — General Information
Tire Pressure
Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort And Vehicle Stability Safety
Both underinflation and overinflation affect the
stability of the vehicle and can produce a feeling
of sluggish response or over responsiveness in
the steering.
NOTE:
Unequal tire pressures from side to side may
cause erratic and unpredictable steering
response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
resistance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
abnormal wear patterns and reduced tread life,
resulting in the need for earlier tire replace -
ment.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfort -
able ride. Over-inflation produces a jarring and
uncomfortable ride.
WARNING!
Overloading of your tires is dangerous.
Overloading can cause tire failure, affect
vehicle handling, and increase your stopping
distance. Use tires of the recommended load
capacity for your vehicle. Never overload
them.WARNING!
Improperly inflated tires are dangerous and
can cause collisions.
Underinflation increases tire flexing and
can result in overheating and tire failure.
Overinflation reduces a tire's ability to
cushion shock. Objects on the road and
chuckholes can cause damage that result
in tire failure.
Overinflated or underinflated tires can
affect vehicle handling and can fail
suddenly, resulting in loss of vehicle
control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle
to drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.

Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
Wheel Mounting Surface
Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/
bolt (do not insert it halfway).
Torque Patterns After 25 miles (40 km), check the lug nut/bolt
torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.
FUEL REQUIREMENTS
3.6L Engine
This engine is designed to meet all
emissions regulations and provide
optimum fuel economy and perfor-
mance when using high quality
unleaded “Regular” gasoline having a posted
octane number of 87 as specified by the (R+M)/
2 method. The use of higher octane “Premium”
gasoline is not required, as it will not provide
any benefit over “Regular” gasoline in these
engines. While operating on gasoline with an octane
number of 87, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see your dealer immediately.
Use of gasoline with an octane number lower
than 87 can cause engine failure and may void
or not be covered by the New Vehicle Limited
Warranty.
Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.Reformulated Gasoline
Many areas of the country require the use of
cleaner burning gasoline referred to as “Refor
-
mulated Gasoline”. Reformulated gasoline
contains oxygenates and are specifically
blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recom -
mended. Properly blended reformulated
gasoline will provide improved performance
and durability of engine and fuel system
components.
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully
until the vehicle has been lowered. Failure to
follow this warning may result in personal
injury.

TECHNICAL SPECIFICATIONS193
Materials Added To Fuel
Besides using unleaded gasoline with the
proper octane rating, gasolines that contain
detergents, corrosion and stability additives are
recommended. Using gasolines that have these
additives will help improve fuel economy,
reduce emissions, and maintain vehicle perfor -
mance.
Designated TOP TIER Detergent Gaso -
line contains a higher level of deter -
gents to further aide in minimizing
engine and fuel system deposits.
When available, the usage of TOP TIER Deter -
gent gasoline is recommended. Visit
www.toptiergas.com for a list of TOP TIER Deter -
gent Gasoline Retailers.
Indiscriminate use of fuel system cleaning
agents should be avoided. Many of these mate -
rials intended for gum and varnish removal may
contain active solvents or similar ingredients.
These can harm fuel system gasket and
diaphragm materials.
Gasoline/Oxygenate Blends
Some fuel suppliers blend unleaded gasoline
with oxygenates such as ethanol. Problems that result from using gasoline
containing more than 15% ethanol (E-15) or
gasoline containing methanol are not the
responsibility of the manufacturer and may void
or not be covered under New Vehicle Limited
Warranty.
Do Not Use E-85 In Non-Flex Fuel Vehicles
Non-Flex Fuel Vehicles (FFV) are compatible
with gasoline containing up to 15% ethanol
(E-15). Use of gasoline with higher ethanol
content may void the New Vehicle Limited
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.
CNG And LP Fuel System Modifications
Modifications that allow the engine to run on
Compressed Natural Gas (CNG) or Liquid
Propane (LP) may result in damage to the
engine, emissions, and fuel system compo
-
nents. Problems that result from running CNG
or LP are not the responsibility of the manufac -
turer and may void or not be covered under the
New Vehicle Limited Warranty.
CAUTION!
DO NOT use E-85, gasoline containing
methanol, or gasoline containing more than
15% ethanol (E-15). Use of these blends may
result in starting and drivability problems,
damage critical fuel system components,
cause emissions to exceed the applicable
standard, and/or cause the Malfunction
Indicator Light to illuminate. Please observe
pump labels as they should clearly
communicate if a fuel contains greater than
15% ethanol (E-15).

MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl
(MMT) is a manganese-containing metallic addi -
tive 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 emissions system
performance in some vehicles. The manufac -
turer recommends that gasoline without MMT
be used in your vehicle. The MMT content of
gasoline may not be indicated on the gasoline
pump; therefore, you should ask your gasoline
retailer whether the gasoline contains MMT.
MMT is prohibited in Federal and California
reformulated gasoline.
Fuel System Cautions
NOTE:
Intentional tampering with the emissions
control system can result in civil penalties being
assessed against you.
Carbon Monoxide Warnings
CAUTION!
Follow these guidelines to maintain your
vehicle’s performance:
The use of leaded gasoline is prohibited by
Federal law. Using leaded gasoline can
impair engine performance and damage
the emissions control system.
An out-of-tune engine or certain fuel or igni -
tion malfunctions can cause the catalytic
converter to overheat. If you notice a
pungent burning odor or some light smoke,
your engine may be out of tune or malfunc -
tioning and may require immediate service.
Contact an authorized dealer for service
assistance.
The use of fuel additives, which are now
being sold as octane enhancers, is not
recommended. Most of these products
contain high concentrations of methanol.
Fuel system damage or vehicle perfor -
mance problems resulting from the use of
such fuels or additives is not the responsi -
bility of the manufacturer and may void or
not be covered under the New Vehicle
Limited Warranty.
CAUTION!
(Continued)

WARNING!
Carbon monoxide (CO) in exhaust gases is
deadly. Follow the precautions below to
prevent carbon monoxide poisoning:
Do not inhale exhaust gases. They contain
carbon monoxide, a colorless and odorless
gas, which can kill. Never run the engine in
a closed area, such as a garage, and never
sit in a parked vehicle with the engine
running for an extended period. If the
vehicle is stopped in an open area with the
engine running for more than a short
period, adjust the ventilation system to
force fresh, outside air into the vehicle.
Guard against carbon monoxide with
proper maintenance. Have the exhaust
system inspected every time the vehicle is
raised. Have any abnormal conditions
repaired promptly. Until repaired, drive with
all side windows fully open.
