CHECKING OIL LEVEL — 3.6L AND 5.7L
E
NGINE
To ensure 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 cross -
hatch markings on the dipstick.
Adding 1 Quart (1.0 Liter) 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.
CHECKING OIL LEVEL — 6.2L
S
UPERCHARGED ENGINE AND 6.4L
E
NGINE
To ensure 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.
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.CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine.
CAUTION!
Overfilling or underfilling the crankcase will
cause aeration or loss of oil pressure. This
could damage your engine.
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.

Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner
filters varies considerably. Only high quality
filters should be used to ensure most efficient
service. Mopar engine air cleaner filters are a
high quality filter and are recommended.
T/A Air Filter Maintenance — If Equipped
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 air filter 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.
4. Using the Mopar Performance Air Filter Service Kit, spray oil evenly along the crown
of each filter pleat holding the nozzle about
3 inches (76 mm) away from the air filter.
One spray per 2 square inches
(1,290 square mm) of air filter. With one
complete coat of oil, let it wick (saturate) for
about 20 minutes, and if required touch up
any light areas on either side of the filter.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.

AIR CONDITIONER MAINTENANCE
For best possible performance, your air
conditioner should be checked and serviced by
an authorized dealer at the start of each warm
season. This service should include cleaning of
the condenser fins and a performance test.
Drive belt tension should also be checked at
this time.
Refrigerant Recovery And Recycling
R-134a — If Equipped
R-134a Air Conditioning Refrigerant is a
hydrofluorocarbon (HFC) that is an
ozone-friendly substance. 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
PAG compressor oil and refrigerants.
Refrigerant Recovery And Recycling
R-1234yf — If Equipped
R–1234yf Air Conditioning Refrigerant is a
hydrofluoroolefin (HFO) that is endorsed by the
Environmental Protection Agency and is an
ozone-friendly substance with a low
global-warming potential. The manufacturer
recommends that air conditioning service be
performed by an authorized dealer using
recovery and recycling equipment.
NOTE:
Use only manufacturer approved A/C system
PAG compressor oil, and refrigerants.
WARNING!
Use only refrigerants and compressor lubri -
cants approved by the manufacturer for
your air conditioning system. Some unap -
proved 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, for
further warranty information.
The air conditioning system contains refrig -
erant 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.

Tire Tread

These indicators are molded into the bottom of
the tread grooves. They will appear as bands
when the tread depth becomes a 1/16 of an
inch (1.6 mm). When the tread is worn to the
tread wear indicators, the tire should be
replaced.
Refer to “Replacement Tires” in this section for
further information.
Life Of Tire
The service life of a tire is dependent upon
varying factors including, but not limited to:
Driving style.
Tire pressure - Improper cold tire inflation
pressures can cause uneven wear patterns
to develop across the tire tread. These
abnormal wear patterns will reduce tread life,
resulting in the need for earlier tire replace -
ment.
Distance driven.
Performance tires, tires with a speed rating of
V or higher, and Summer tires typically have
a reduced tread life. Rotation of these tires
per the vehicle scheduled maintenance is
highly recommended. NOTE:
Wheel valve stem must be replaced as well
when installing new tires due to wear and tear
in existing tires.
Keep dismounted tires in a cool, dry place with
as little exposure to light as possible. Protect
tires from contact with oil, grease, and gasoline.
Replacement Tires
The tires on your new vehicle provide a balance
of many characteristics. They should be
inspected regularly for wear and correct cold
tire inflation pressures. The manufacturer
strongly recommends that you use tires
equivalent to the originals in size, quality and
performance when replacement is needed.
Refer to the paragraph on “Tread Wear
Indicators” in this section. Refer to the Tire and
Loading Information placard or the Vehicle
Certification Label for the size designation of
your tire. The Load Index and Speed Symbol for
your tire will be found on the original equipment
tire sidewall.
See the Tire Sizing Chart example found in the
“Tire Safety Information” section of this manual
for more information relating to the Load Index
and Speed Symbol of a tire.
1 — Worn Tire
2 — New Tire
WARNING!
Tires and the spare tire should be replaced
after six years, regardless of the remaining
tread. Failure to follow this warning can result
in sudden tire failure. You could lose control
and have a collision resulting in serious injury
or death.
