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 OAT coolant (conforming to

MS-12106) only 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.

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).

page 273.

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 antirust 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

The 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 to use the

same engine coolant (OAT coolant conforming to

MS.90032) throughout the life of your vehicle.

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 and turn the

ignition to the OFF mode. The fan is tempera

-

ture controlled and can start at any time the

ignition is in the ON mode.

SERVICING AND MAINTENANCE

Please review these recommendations for using

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 recovery tank.
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.

If ingested by a child or pet, seek emergency

assistance immediately. Clean up any ground spills

immediately.

Coolant Level

The coolant expansion bottle provides a quick

visual method for determining that the coolant

level is adequate. With engine off and cold, the

level of the engine coolant (antifreeze) in the bottle

should be between the “MIN” and “MAX” marks.

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.

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.

SERVICING AND MAINTENANCE

235

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.



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 222.

Fluid Level Check — Brake Master Cylinder

The fluid level of the master cylinder should be

checked when performing under the hood service

or immediately if the Brake System Warning Light

indicates system failure. If necessary, add fluid to

bring level within the designated marks on the side

of the reservoir of the brake master cylinder. Be

sure to clean the top of the master cylinder area

before removing cap. With disc brakes the fluid

level can be expected to fall as the brake linings

wear. However, an unexpected drop in fluid level

may be caused by a leak and a system check

should be conducted

Ú

page 273.

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 the manufacturer recommended

brake fluid

Ú

page 273. 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 an 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.



Do not allow petroleum-based fluid to contami

-

nate the brake fluid. Brake seal components could

be damaged, causing partial or complete brake

failure. This could result in a collision.

RANSMISSION

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 274. 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.

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.

The only exception to this policy is the use of

special dyes for diagnosing fluid leaks in 9-speed

transmissions. 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 filler tube is capped and no dipstick

is provided. An authorized dealer can check your

transmission fluid level using a special service dipstick.

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.

USES

General Information

The fuses protect electrical systems against

excessive current.
When a device does not work, you must check the fuse

element inside the blade fuse for a break/melt.

CAUTION!

Using a transmission fluid other than the

manufacturer recommended fluid may cause

deterioration in transmission shift quality and/or

torque converter shudder

Ú

page 274.

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.
