(Continued)

Under normal operating conditions, the catalytic

converter will not require maintenance. However, it

is important to keep the engine properly tuned to

ensure proper catalyst operation and prevent

possible catalyst damage.

NOTE:

Intentional tampering with emissions control

systems can result in civil penalties being

assessed against you.
In unusual situations involving grossly

malfunctioning engine operation, a scorching odor

may suggest severe and abnormal catalyst

overheating. If this occurs, stop the vehicle, turn off

the engine and allow it to cool. Service, including a

tune-up to manufacturer's specifications, should

be obtained immediately.

To minimize the possibility of catalytic converter

damage:



Do not interrupt the ignition when the transmis

-

sion is in gear and the vehicle is in motion.



Do not try to start the vehicle by pushing or

towing the vehicle.



Do not idle the engine with any ignition compo

-

nents disconnected or removed, such as when

diagnostic testing, or for prolonged periods

during very rough idle or malfunctioning oper

-

ating conditions.

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, the system should be drained, flushed, and

refilled with fresh Organic Additive Technology

(OAT) coolant (conforming to MS.90032) by an

authorized dealer. Check the front of the A/C

condenser for any accumulation of bugs, leaves,

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

garden hose vertically down the face of the

condenser.
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.



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.



When working near the radiator cooling fan,

disconnect the fan motor lead or turn the igni

-

tion to the OFF position. The fan is tempera

-

ture controlled and can start at any time the

ignition is in the ON position.

SERVICING AND MAINTENANCE

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 Organic Additive

Technology (OAT) coolant (conforming to

MS.90032).
For the proper maintenance intervals

Selection Of Coolant

For further information

Ú

page 293.

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 ten 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.

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 a local 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 a 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

by a child or pet, seek emergency assistance

immediately.

Coolant Level

The coolant expansion bottle provides a quick

visual method for determining that the coolant

level is adequate. With the engine off and cold, the

level of the coolant (antifreeze) in the bottle should

be between the “MAX” and “MIN” lines marked on

the bottle.
As long as the engine operating temperature is

satisfactory, the coolant bottle need only be

checked once a month.

When additional coolant is needed to maintain the

proper level, it should be added to the coolant

bottle. Do not overfill.
See an authorized dealer for service.

Cooling System Notes

NOTE:

When the vehicle is stopped after a few miles/kilo

-

meters of operation, you may observe vapor

coming from the front of the engine compartment.

This is normally a result of moisture from rain,

snow, or high humidity accumulating on the

radiator and being vaporized when the thermostat

opens, allowing hot engine coolant (antifreeze) to

enter the radiator.
If an examination of your engine compartment

shows no evidence of radiator or hose leaks, the

vehicle may be safely driven. The vapor will soon

dissipate.



Do not overfill the coolant expansion bottle.



Check the coolant freeze point in the radiator

and in the coolant expansion bottle. If engine

coolant needs to be added, the contents of the

coolant expansion bottle must also be protected

against freezing.

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.

WARNING!

SERVICING AND MAINTENANCE

(Continued)



If frequent engine coolant additions are

required, the cooling system should be pressure

tested for leaks.



Maintain engine coolant concentration at a

minimum of 50% OAT coolant (conforming to

MS.90032) and distilled water for proper corro

-

sion protection of your engine which contains

aluminum components.



Make sure that the coolant expansion bottle

overflow hoses are not kinked or obstructed.



Keep the front of the radiator clean. If your

vehicle is equipped with air conditioning, keep

the front of the condenser clean.



Do not change the thermostat for Summer or

Winter operation. If replacement is ever neces

-

sary, install ONLY the correct type thermostat.

Other designs may result in unsatisfactory

engine cooling performance, poor gas mileage,

and increased emissions.

In order to ensure brake system performance, all

brake system components should be inspected

periodically

Ú

page 236.

Brake Master Cylinder

The fluid level in the master cylinder should be

checked when performing under hood services, or

immediately if the “Brake Warning Light” is on.
Be sure to clean the top of the master cylinder area

before removing the cap. If necessary, add fluid to

bring the fluid level up to the requirements

described on the brake fluid reservoir. Fluid level

can be expected to fall as the brake pads wear. The

brake fluid level should be checked when the pads

are replaced. However, low fluid level may be

caused by a leak and a checkup may be needed.
Use only manufacturer's recommended brake fluid

Ú

page 293.

WARNING!

Riding the brakes can lead to brake failure and

possibly a collision. Driving with your foot resting

or riding on the brake pedal can result in

abnormally high brake temperatures, excessive

lining wear, and possible brake damage. You

would not have your full braking capacity in an

emergency.

WARNING!



Use only manufacturer’s recommended brake

fluid

Ú

page 293. Using the wrong type of

brake fluid can severely damage your brake

system and/or impair its performance. The

proper type of brake fluid for your vehicle is

also identified on the original factory installed

hydraulic master cylinder reservoir.



To avoid contamination from foreign matter or

moisture, use only new brake fluid or fluid that

has been in a tightly closed container. Keep

the master cylinder reservoir cap secured at

all times. Brake fluid in a open container

absorbs moisture from the air resulting in a

lower boiling point. This may cause it to boil

unexpectedly during hard or prolonged

braking, resulting in sudden brake failure. This

could result in a collision.



Overfilling the brake fluid reservoir can result

in spilling brake fluid on hot engine parts,

causing the brake fluid to catch fire. Brake

fluid can also damage painted and vinyl

surfaces, care should be taken to avoid its

contact with these surfaces.

Special Additives

The manufacturer strongly recommends against

using any special additives in the transmission.

Automatic Transmission Fluid (ATF) is an

engineered product and its performance may be

impaired by supplemental additives. Therefore, do

not add any fluid additives to the transmission.

Avoid using transmission sealers as they may

adversely affect seals.

Fluid Level Check

The fluid level is preset at the factory and does not

require adjustment under normal operating

conditions. Routine fluid level checks are not

required, therefore the transmission has no

dipstick. An authorized dealer can check your

transmission fluid level using special service tools.

If you notice fluid leakage or transmission

malfunction, visit an authorized dealer

immediately to have the transmission fluid level

checked. Operating the vehicle with an improper

fluid level can cause severe transmission damage.

Fluid And Filter Changes

Under normal operating conditions, the fluid

installed at the factory will provide satisfactory

lubrication for the life of the vehicle.
Routine fluid and filter changes are not required.

However, change the fluid and filter if the fluid

becomes contaminated (with water, etc.), or if the

transmission is disassembled for any reason.

Selection Of Lubricant

It is important to use the proper transmission fluid

to ensure optimum transmission performance and

life. Use the manufacturer specified transmission

fluid

Ú

page 293. It is important to maintain the

transmission fluid at the correct level using the

recommended fluid.

NOTE:

No chemical flushes should be used in any trans

-

mission; only the approved lubricant should be

used.



Do not allow petroleum based fluid to contam

-

inate the brake fluid. Brake seal components

could be damaged, causing partial or

complete brake failure. This could result in a

collision.

CAUTION!

Use of improper brake fluids will affect overall

clutch system performance. Improper brake

fluids may damage the clutch system resulting in

loss of clutch function and the ability to shift the

transmission.

WARNING!

CAUTION!

Do not use chemical flushes in your

transmission as the chemicals can damage your

transmission components. Such damage is not

covered by the New Vehicle Limited Warranty.

CAUTION!

If a transmission fluid leak occurs, visit an

authorized dealer immediately. Severe

transmission damage may occur. An authorized

dealer has the proper tools to adjust the fluid

level accurately.

CAUTION!

Using a transmission fluid other than the

manufacturer recommended fluid may cause

deterioration in transmission shift quality and/or
