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 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.
There are four 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.



Crosshatched zone marked with dimples at the

MIN and the MAX ends of the range.

NOTE:

Always maintain the oil level within the crosshatch

markings on the dipstick.
Adding 1 quart (1 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.

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 antifreeze). 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.

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 container, aids

cleaning action, reduces the freezing point to avoid

line clogging, and is not harmful to paint or trim.

Your vehicle is equipped with a maintenance-free

battery. You will never have to add water, and

periodic maintenance is not required.

CAUTION!

Overfilling or underfilling the crankcase will

cause oil 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.

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

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

An authorized dealer has the qualified service

perform all service operations in an expert

manner. Service Manuals are available which

include detailed service information for your

vehicle. Refer to these Service Manuals before

page 439.

NOTE:

Hemi engines (6.4L) at times can tick right after

startup and then quiet down after approximately

30 seconds. This is normal and will not harm the

engine. This characteristic can be caused by short

drive cycles. For example, if the vehicle is started

then shut off after driving a short distance. Upon

restarting, you may experience a ticking sound.

Other causes could be if the vehicle is unused for an

extended period of time, incorrect oil, extended oil

changes or extended idling. If the engine continues

to tick or if the Malfunction Indicator Light (MIL)

comes on, see the nearest authorized dealer.

Engine Oil Selection — Diesel Engine

Use only the manufacturer's recommended fluid

Ú

page 439.

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 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.

CAUTION!

Precautions have been taken to safeguard all

parts and connections however, the pressure

generated by these machines is such that

complete protection against water ingress

cannot be guaranteed.

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 equip

perform a service job, take your vehicle to a

competent mechanic.

American Petroleum Institute (API)

Approved Engine Oil

These symbols mean that the oil has been certified

by the API. The manufacturer only recommends API

trademark oils.

The API Starburst trademark certifies

0W-20, 0W-30 and 5W-30 engine oils.

The API Donut trademark certifies 0W-40

and 5W-40 engine oil.

For diesel engines, oils with a high ash content may

produce damaging deposits on cylinder head

valves and/or after treatment system damage. A

maximum sulfated ash content of 1.00 mass % is

recommended for all oil used in the engine.
The same oil change interval is to be followed for

synthetic oil as for petroleum-based oil. Also,

synthetic oil must meet the same performance

specifications as petroleum oil.

Synthetic Engine Oils

Your engine was designed for synthetic engine oils,

only use synthetic API approved engine oils.
Synthetic engine oils which do not have both the

correct API trademark and the correct SAE viscosity

grade numbers should not be used.

Materials Added To Engine Oil

The manufacturer strongly recommends against

the addition 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 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.

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.

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
