Checking Oil Level — 3.6L And 5.7L Engine
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 month. The best time to
check the engine oil level is about five minutes after a fully
warmed up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings.
There are three possible dipstick types,
•Crosshatched zone.
• Crosshatched zone marked SAFE.
• Crosshatched zone marked with MIN at the low end of
the range and MAX at the high end of the range.
NOTE: Always maintain the oil level within the crosshatch
markings on the dipstick.
Adding 1 quart (1.0 liters) of oil when the reading is at the
low end of the dipstick range will raise the oil level to the
high end of the range marking.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.
Checking Oil Level — 6.4L Engine
To assure proper engine lubrication, the engine oil must be
maintained at the correct level. Check the oil level at
regular intervals, such as once a month. 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 in the “SAFE” range. Adding 1.0 quart (1 liter) of
oil when the reading is at the bottom of the “SAFE” range
will result in an oil level at the top of the “SAFE” range on
these engines.
CAUTION!
Overfilling or underfilling the crankcase will cause
aeration or loss of oil pressure. This could damage your
engine.

Adding Washer Fluid
The windshield washer fluid reservoir is located in the
front of the engine compartment. Be sure to check the fluid
level 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 water.
When refilling the washer fluid reservoir, apply some
washer fluid to a cloth or towel and wipe the wiper blades
clean. 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.
The fluid reservoir will hold nearly 1 gallon (4 liters) of
washer fluid when the message “Low Washer Fluid”
appears in the instrument cluster.
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.
Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic mainte-
nance required.
NOTE:The battery is stored under an access cover in the
trunk. Remote battery terminals are located in the engine
compartment for jump starting. Refer to “Jump Starting
Procedures” in “In Case Of Emergency” for further infor-
mation.

Clean Engine Air Filter
The scheduled air filter cleaning interval is 30,000 miles
(48,280 km), or if in a dusty environment the engine air filter
should be checked periodically to ensure optimal air flow.
Cleaning your engine air filter with the recommended
Mopar Performance Air Filter Service Kit is not required if
you can still see any part the wire screen on the entire air
filter regardless of how dirty it may appear. When any part
of the wire screen is no longer visible on the air filter, that
is an indication it is time to clean the air filter.
1. Spray the air filter with the recommended Mopar airfilter cleaner and let sit for at least 10 minutes to loosen
dirt, before rinsing.
NOTE: Never use strong detergents, high pressure, or
gasoline on air filter. 2. Rinse the air filter with cool low-pressure water applied
from the inside (clean side) out in order to flush the dirt
out of the filter. Continue to rinse the filter until all
traces of the cleaner have been removed.
NOTE: It may be necessary to repeat steps 1 and 2 if the air
filter is not completely clean.
3. After rinsing the air filter, gently shake off the excess water and allow air filter to dry naturally. Do not apply
oil until air filter is completely dry.
NOTE: Do not use forced air pressure as it may damage the
filtering capabilities of the filter ’s microfibers and also void
its warranty.
