Checking Oil Level — Gas Engine
To assure proper lubrication of your vehicle’s engine, 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 up engine is shut off.
Checking the oil while the vehicle is on level ground will
improve the accuracy of the oil level readings. Always
maintain the oil level within the SAFE zone on the dipstick.
Adding one quart of oil when the reading is at the bottom
of the SAFE zone will result in a reading at the top of the
safe zone on these engines.
CAUTION!
Overfilling or underfilling will cause oil aeration or
loss of oil pressure. This could damage your engine.
Adding Washer Fluid
The fluid reservoir is located under the hood and should be
checked for fluid level at regular intervals. Fill the reservoir
with windshield washer solvent only (not radiator anti-
freeze). When refilling the washer fluid reservoir, take
some washer fluid and apply it 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.
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.
After the engine has warmed up, operate the defroster for
a few minutes to reduce the possibility of smearing or
freezing the fluid on the cold windshield. Windshield
washer solution used with water as directed on the con-
tainer, aids cleaning action, reduces the freezing point to
avoid line clogging, and is not harmful to paint or trim.
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.

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 Emergency” 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 accessories con-
tain lead and lead compounds. Wash hands after
handling.
CAUTION!
• It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to the
(Continued)
CAUTION! (Continued)
negative post. Battery posts are marked positive (+)
and negative (-) and are identified on the battery
case. Cable clamps should be tight on the terminal
posts and free of corrosion.
• If a “fast charger” is used while the battery is in the
vehicle, disconnect both vehicle battery cables before
connecting the charger to the battery. Do not use a
“fast charger” to provide starting voltage.
DEALER SERVICE
Your authorized dealer has the qualified service personnel,
special tools, and equipment to perform all service opera-
tions in an expert manner. Service Manuals are available
which include detailed service information for your ve-
hicle. Refer to these Service Manuals before attempting any
procedure yourself.
NOTE: Intentional tampering with emissions control sys-
tems may void your warranty and could result in civil
penalties being assessed against you.
366 SERVICING AND MAINTENANCE

WARNING!
You can be badly injured working on or around a
motor vehicle. Only do service work for which you
have the knowledge and the proper equipment. If you
have any doubt about your ability to perform a service
job, take your vehicle to a competent mechanic.
Engine Oil — Gas Engine
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 “Scheduled Servicing” in this chapter for further
information.
NOTE:Under no circumstances should oil change inter-
vals exceed 8,000 miles (13,000 km), twelve months or 350
hours of engine run time, whichever comes first. The 350
hours of engine run or idle time is generally only a concern
for fleet customers.
Engine Oil Selection — 6.4L
For best performance and maximum protection under all
types of operating conditions, the manufacturer only rec-
ommends engine oils that are API Certified and meet the
requirements of FCA Material Standard MS-12633.
American Petroleum Institute (API) Engine Oil
Identification Symbol
This symbol means that the oil has
been certified by the American Pe-
troleum Institute (API). The manu-
facturer only recommends API Cer-
tified engine oils.
This symbol certifies 0W-20, 5W-20,
0W-30, 5W-30 and 10W-30 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.

SERVICING AND MAINTENANCE 367

Engine Oil Viscosity (SAE Grade) — 6.4L Engine
Use Mopar SAE 0W-40 engine oil approved to FCA Mate-
rial Standard MS-12633 such as Pennzoil Ultra equivalent
is recommended for 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 the “Engine Compart-
ment” illustration in this section.
Lubricants which do not have both the engine oil certifi-
cation mark and the correct SAE viscosity grade number
should not be used.
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 addi-
tion of any additives (other than leak detection dyes) to theengine 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 dispos-
able 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 high quality oil filters
and are recommended.
Engine Air Cleaner Filter
Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.
368 SERVICING AND MAINTENANCE

NOTE:Be sure to follow the “Severe Duty Conditions”
maintenance interval if applicable.
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 ve-
hicle 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 used to
assure most efficient service. Mopar engine air cleaner
filters are a high quality filter and are recommended.
Engine Air Cleaner Filter Inspection and
Replacement
