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 Ultra
0W-40 engine or equivalent MOPAR oil meeting the FCA
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.

engine oils.
This symbol certifies 0W-20, 5W-20, 0W-30, 5W-30 and
10W-30 engine oils.

Engine Oil Viscosity
Use Pennzoil Ultra 0W-40 engine or equivalent MOPAR
oil meeting the FCA 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-

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.
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 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
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.
Engine Air Cleaner Filter Selection
The quality of replacement engine air cleaner filters
varies considerably. Only high quality filters should be

Maintenance-Free Battery
Your vehicle is equipped with a maintenance-free battery.
You will never have to add water, nor is periodic main-
tenance required.
CAUTION!
•Do not use a portable battery booster pack or any
other booster source with a system voltage greater
than 12 Volts or damage to the battery, starter
motor, alternator or electrical system may occur.
• Accessories that can be plugged into the vehicle
power outlets draw power from the vehicle’s bat-
tery, even when not in use (i.e., cellular phones,
etc.). Eventually, if plugged in long enough, the
vehicle’s battery will discharge sufficiently to de-
grade battery life and/or prevent the engine from
starting.
WARNING!
• When temperatures are below the freezing point,
electrolyte in a discharged battery may freeze. Do
not attempt jump-starting because the battery
could rupture or explode and cause personal injury.
Battery temperature must be brought above the
freezing point before attempting a jump-start.
• Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is on. You can be injured by moving
fan blades.
• Remove any metal jewelry such as watch bands or
bracelets that might make an inadvertent electrical
contact. You could be seriously injured.

9. Push the door to the near closed position to reengagethe 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.
