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 (1.0 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.

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

Hemi engines (5.7L) 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

WARNING!



Exhaust gases can injure or kill. They contain

Carbon Monoxide (CO), which is colorless and

odorless. Breathing it can make you uncon

-

scious and can eventually poison you. To

avoid breathing CO see

Ú

page 372.



A hot exhaust system can start a fire if you

park over materials that can burn. Such mate

-

rials might be grass or leaves coming into

contact with your exhaust system. Do not park

or operate your vehicle in areas where your

exhaust system can contact anything that can

burn.

CAUTION!



The catalytic converter requires the use of

unleaded fuel only. Leaded gasoline will

destroy the effectiveness of the catalyst as an

emissions control device and may seriously

reduce engine performance and cause

serious damage to the engine.



Damage to the catalytic converter can result if

your vehicle is not kept in proper operating

condition. In the event of engine malfunction,

particularly involving engine misfire or other

apparent loss of performance, have your

vehicle serviced promptly. Continued opera

-

tion of your vehicle with a severe malfunction

could cause the converter to overheat,

resulting in possible damage to the converter

and vehicle.

CAUTION!

WARNING!



You or others can be badly burned by hot

engine coolant (antifreeze) or steam from your

radiator. If you see or hear steam coming from

under the hood, do not open the hood until the

radiator has had time to cool. Never open a

cooling system pressure cap when the radi

-

ator or coolant bottle is hot.



Keep hands, tools, clothing, and jewelry away

from the radiator cooling fan when the hood is

raised. The fan starts automatically and may

start at any time, whether the engine is

running or not.

SERVICING AND MAINTENANCE

Engine Coolant Checks

Check the engine coolant (antifreeze) protection

every 12 months (before the onset of freezing

weather, where applicable). If the engine coolant is

dirty or rusty in appearance, the system should be

drained, flushed and refilled with fresh coolant.

Check the front of the A/C condenser (if equipped)

or radiator for any accumulation of bugs, leaves,

etc. If dirty, clean by gently spraying water from a

garden hose vertically down the face of the A/C

condenser (if equipped) or the back of the radiator

core.
Check the engine cooling system hoses for brittle

rubber, cracking, tears, cuts and tightness of the

connection at the coolant recovery bottle and

radiator. Inspect the entire system for leaks.
DO NOT REMOVE THE COOLANT PRESSURE CAP

WHEN THE COOLING SYSTEM IS HOT.

Cooling System — Drain, Flush And Refill

NOTE:

Some vehicles require special tools to add coolant

properly. Failure to fill these systems properly

could lead to severe internal engine damage. If any

coolant is needed to be added to the system

please contact an authorized dealer.
If the engine coolant (antifreeze) is dirty or

contains visible sediment, have an authorized

dealer clean and flush with OAT coolant

(conforming to MS.90032).

NOTE:



Mixing of engine coolant (antifreeze) other than

specified Organic Additive Technology (OAT)

engine coolant, may result in engine damage

and may decrease corrosion protection. OAT

engine coolant is different and should not be

mixed with Hybrid Organic Additive Technology

(HOAT) engine coolant or any “globally compat

-

ible” coolant. If a non-OAT engine coolant is

introduced into the cooling system in an emer

-

gency, the cooling system will need to be

drained, flushed, and refilled with fresh OAT

coolant (conforming to MS.90032), by an autho

-

rized dealer as soon as possible.



Do not use water alone or alcohol-based engine

coolant products. Do not use additional rust

inhibitors or anti-rust products, as they may not

be compatible with the radiator engine coolant

and may plug the radiator.



This vehicle has not been designed for use with

propylene glycol-based engine coolant. Use of

propylene glycol-based engine coolant is not

recommended.



Some vehicles require special tools to add

coolant properly. Failure to fill these systems

properly could lead to severe internal engine

damage. If any coolant is needed to be added to

the system please contact an authorized dealer.

Adding Coolant

Your vehicle has been built with an improved

engine coolant (OAT coolant conforming to

MS.90032) that allows extended maintenance

intervals. This engine coolant (antifreeze) can be

used up to 10 years or 150,000 miles

(240,000 km) before replacement. To prevent

reducing this extended maintenance period, it is

important that you use the same engine coolant

(OAT coolant conforming to MS.90032) throughout

the life of your vehicle.



When working near the radiator cooling fan,

disconnect the fan motor lead or turn the igni

-

tion to the OFF mode. The fan is temperature

controlled and can start at any time the igni

-

tion is in the ON mode.

SERVICING AND MAINTENANCE

Please review these recommendations for using

Organic Additive Technology (OAT) engine coolant

that meets the requirements of the manufacturer

Material Standard MS.90032. When adding

engine coolant:



We recommend using Mopar® Antifreeze/

Coolant 10 Year/150,000 Mile (240,000 km)

Formula OAT that meets the requirements of the

manufacturer Material Standard MS.90032.



Mix a minimum solution of 50% OAT engine

coolant that meets the requirements of the

manufacturer Material Standard MS.90032

and distilled water. Use higher concentrations

(not to exceed 70%) if temperatures below

−34°F (−37°C) are anticipated. Please contact

an authorized dealer for assistance.



Use only high purity water such as distilled or

deionized water when mixing the water/engine

coolant solution. The use of lower quality water

will reduce the amount of corrosion protection

in the engine cooling system.

NOTE:



It is the owner's responsibility to maintain the

proper level of protection against freezing

according to the temperatures occurring in the

area where the vehicle is operated.



Some vehicles require special tools to add

coolant properly. Failure to fill these systems

properly could lead to severe internal engine

damage. If any coolant is needed to be added to

the system, please contact an authorized

dealer.



Mixing engine coolant types is not recom

-

mended and can result in cooling system

damage. If HOAT and OAT coolant are mixed in

an emergency, have an authorized dealer drain,

flush, and refill with OAT coolant (conforming to

MS.90032) as soon as possible.

Cooling System Pressure Cap

The cap must be fully tightened to prevent loss of

engine coolant (antifreeze), and to ensure that

engine coolant will return to the radiator from the

coolant expansion bottle/recovery tank (if

equipped).
The cap should be inspected and cleaned if there

is any accumulation of foreign material on the

sealing surfaces.

Disposal Of Used Coolant

Used ethylene glycol-based coolant (antifreeze) is

a regulated substance requiring proper disposal.

Check with your local authorities to determine the

disposal rules for your community. To prevent

ingestion by animals or children, do not store

ethylene glycol-based coolant in open containers

or allow it to remain in puddles on the ground,

clean up any ground spills immediately. If ingested,

seek emergency assistance immediately.

WARNING!



Do not open hot engine cooling system. Never

add engine coolant (antifreeze) when the

engine is overheated. Do not loosen or

remove the cap to cool an overheated engine.

Heat causes pressure to build up in the

cooling system. To prevent scalding or injury,

do not remove the pressure cap while the

system is hot or under pressure.



Do not use a pressure cap other than the one

specified for your vehicle. Personal injury or

engine damage may result.
