Engine Oil
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 in the “SAFE” range. Adding one quart 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.
NOTE:Fill engine oil one quart at a time.
CAUTION!
•Overfilling or underfilling will cause oil aeration
or loss of oil pressure. This could damage your
engine.
•
Operating the engine with the oil levels below the
safe zone, or operating with oil levels that exceed the
top of the safe zone may cause engine damage.
Change Engine Oil
The oil change indicator system will remind you that it is
time to take your vehicle in for scheduled maintenance.
Refer to “Maintenance Schedule” for further information.
NOTE:Under no circumstances should oil change inter-
vals exceed 6,000 miles (10,000 km) or six months,
whichever occurs first.

Engine Oil Selection
For best performance and maximum protection under all
types of operating conditions, the manufacturer only
recommends full synthetic engine oils that meet the
American Petroleum Institute (API) categories of SN.
The manufacturer recommends the use of Pennzoil Ul-
tra™ 0W-40 engine or equivalent MOPAR® oil meeting
the FCA US Material Standard MS-12633 for use in all
operating temperatures.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in “Maintaining Your Vehicle” for further informa-
tion.
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.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American
Petroleum Institute (API). The
manufacturer only recommends
API Certified engine oils.

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.
Engine Oil Viscosity
Use Pennzoil Ultra™ 0W-40 engine or equivalent
MOPAR® oil meeting the FCA US Material Standard
MS-12633 for use in all operating temperatures.
The engine oil filler cap also shows the recommended
engine oil viscosity for your engine. For information on
engine oil filler cap location, refer to “Engine Compart-
ment” in “Maintaining Your Vehicle” for further informa-
tion.
Synthetic Engine Oils
You may use synthetic engine oils provided the recom-
mended oil quality requirements are met, and the recom-
mended maintenance intervals for oil and filter changes
are followed.
Materials Added To Engine Oil
The manufacturer strongly recommends against 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 addi-
tives.
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 authorized dealer, service
534 MAINTAINING YOUR VEHICLE

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 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 efficient
service. MOPAR® engine oil filters are a high quality oil
filter and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” in the “Mainte-
nance Schedules” section for the proper maintenance
intervals.
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.

CAUTION!
Do not use chemical flushes in your air conditioning
system as the chemicals can damage your air condi-
tioning components. Such damage is not covered by
the New Vehicle Limited Warranty.
Refrigerant Recovery And Recycling R134a — If
Equipped
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by 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 HFO 1234yf
— If Equipped
HFO 1234yf Air Conditioning Refrigerant is a hydro-
fluoolefine HFO that is endorsed by the Environmental
Protection Agency and is an ozone-saving product with a
low GWP (Global Warming Potential). However, the
manufacturer recommends that air conditioning service
be performed by authorized dealer or other service
facilities using recovery and recycling equipment.
NOTE:Use only manufacturer approved A/C system
PAG compressor oil and refrigerants.
Air Conditioning Filter Replacement (A/C Air
Filter)
Refer to the “Maintenance Schedule” for the proper
maintenance intervals.

9. Push the door to the near closed position to reengage
the glove compartment travel stops.
NOTE:Ensure the glove compartment door hinges and
glove compartment travel stops are fully engaged.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, decklid, sliding doors and hood hinges, should
be lubricated periodically with a lithium based grease,
such as MOPAR® Spray White Lube to assure quiet, easy
operation and to protect against rust and wear. Prior to
the application of any lubricant, the parts concerned
should be wiped clean to remove dust and grit; after
lubricating excess oil and grease should be removed.
Particular attention should also be given to hood latching
components to ensure proper function. When performing
other underhood services, the hood latch, release mecha-
nism and safety catch should be cleaned and lubricated.The external lock cylinders should be lubricated twice a
year, preferably in the Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR®
Lock Cylinder Lubricant directly into the lock cylinder.
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 accumula-
tions 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 windshield.
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.
