Checking Oil Level
To assure proper engine lubrication, the engine 
oil must be maintained at the correct level. 
Check the oil level at regular intervals, such as 
every fuel stop. The best time to check the 
engine oil level is about five minutes after a fully 
warmed engine is shut off.
Checking the oil while the vehicle is on level 
ground will improve the accuracy of the oil level 
readings. Maintain the oil level between the 
MIN and MAX markings on the dipstick. Adding 
one quart or one liter of oil when the reading is 
at the MIN mark will result in a MAX reading on 
these engines.
Adding Washer Fluid 
The fluid reservoir is located in the front of the 
engine compartment. Be sure to check the fluid 
level in the reservoir at regular intervals. Fill the 
reservoir with windshield washer solvent (not 
radiator antifreeze) and operate the system for 
a few seconds to flush out the residual washer 
fluid.
When refilling the washer fluid reservoir, take 
some washer fluid, apply it to a cloth or towel, 
and wipe clean the wiper blades; this will help 
blade performance.
To prevent freeze-up of your windshield washer 
system in cold weather, select a solution or 
mixture that meets or exceeds the temperature 
range of your climate. This rating information 
can be found on most washer fluid containers.
Maintenance-Free Battery 
Your vehicle is equipped with a 
maintenance-free battery. You will never have 
to add water, nor is periodic maintenance 
required.
CAUTION!
Overfilling or underfilling will cause oil aera -
tion, or loss of oil pressure. This could 
damage your engine.
Never use Non-Detergent Oil or Straight 
Mineral Oil in the engine or damage may 
result.
WARNING!
Commercially available windshield washer 
solvents are flammable. They could ignite and 
burn you. Care must be exercised when filling 
or working around the washer solution.
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 immediately with 
large amounts of water. Refer to “Jump 
Starting Procedure” in “In Case Of Emer -
gency” for further information.
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.
Battery posts, terminals, and related acces -
sories contain lead and lead compounds. 
Wash hands after handling.

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 
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 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.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.

360SERVICING AND MAINTENANCE  
(Continued)
Under normal operating conditions, the catalytic 
converter will not require maintenance. However, 
it is important to keep the engine properly tuned 
to ensure proper catalyst operation and prevent 
possible catalyst damage.
NOTE:
Intentional tampering with emissions control 
systems can result in civil penalties being 
assessed against you. In unusual situations involving grossly 
malfunctioning engine operation, a scorching 
odor may suggest severe and abnormal catalyst 
overheating. If this occurs, stop the vehicle, turn 
off the engine and allow it to cool. Service, 
including a tune-up to manufacturer's 
specifications, should be obtained immediately.
To minimize the possibility of catalytic converter 
damage:
Do not interrupt the ignition when the trans
-
mission is in gear and the vehicle is in 
motion.
Do not try to start the vehicle by pushing or 
towing the vehicle.
Do not idle the engine with any ignition 
components disconnected or removed, such 
as when diagnostic testing, or for prolonged 
periods during very rough idle or malfunc -
tioning operating conditions.
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.
WARNING!  (Continued)
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 
replacement.
Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a 
comfortable ride. Overinflation produces a 
jarring and uncomfortable ride.
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 
Do not use E-85 flex fuel or ethanol blends 
greater than 15% in this engine.
These engines are designed to meet all 
emissions regulations and provide 
optimum fuel economy and performance 
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 an authorized 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.
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.

390TECHNICAL SPECIFICATIONS  
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 
“Reformulated Gasoline”. Reformulated 
gasoline contains oxygenates and are 
specifically blended to reduce vehicle 
emissions and improve air quality.
The use of reformulated gasoline is 
recommended. Properly blended reformulated 
gasoline will provide improved performance 
and durability of engine and fuel system 
components.
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 
performance.
Designated TOP TIER Detergent 
Gasoline contains a higher level of 
detergents to further aide in 
minimizing engine and fuel system 
deposits. When available, the usage of TOP 
TIER Detergent gasoline is recommended. Visit 
www.toptiergas.com for a list of TOP TIER 
Detergent Gasoline Retailers.
Indiscriminate use of fuel system cleaning 
agents should be avoided. Many of these 
materials 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.
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).

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 
components. Problems that result from running 
CNG or LP are not the responsibility of the 
manufacturer and may void or not be covered 
under the New Vehicle Limited Warranty.
MMT In Gasoline
Methylcyclopentadienyl Manganese Tricarbonyl 
(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 emissions system 
performance in some vehicles. The 
manufacturer 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
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.

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.
