Cooling System — Drain, Flush And Refill

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).
Refer to the Maintenance Plan in this section for

the proper maintenance intervals

page 248.

Selection Of Coolant

Refer to Engine Fluids And Lubricants for further

information

page 303.

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 is built with 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

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

(Continued)

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 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.

Coolant Level

The coolant bottle provides a quick visual method

for determining that the coolant level is adequate.

With the engine off and cold, the level of the engine

coolant (antifreeze) in the bottle should be

between the ranges indicated on the bottle.
The radiator normally remains completely full, so

there is no need to remove the radiator/coolant

pressure cap unless checking for engine coolant

freeze point or replacing coolant. Advise your

service attendant of this. As long as the engine

operating temperature is satisfactory, the coolant

only needs to be checked once a month.

When additional engine coolant is needed to

maintain the proper level, only OAT coolant that

meets the requirements of the manufacturer

Material Standard MS.90032 should be added to

the coolant bottle. Do not overfill.

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.



If frequent engine coolant additions are

required, the cooling system should be pressure

tested for leaks.

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

267

(Continued)



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.

RAKE

YSTEM

In order to ensure brake system performance, all

brake system components should be inspected

periodically. Refer to the Maintenance Plan for the

proper maintenance intervals

page 248.

Fluid Level Check — Brake Master Cylinder

The fluid level of the brake master cylinder should

be checked whenever the vehicle is serviced, or

immediately if the brake system warning light is on.

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, fluid level can be expected to fall

as the brake pads wear. Brake fluid level should be

checked when pads are replaced. If the brake fluid

is abnormally low, check the system for leaks. For

further information

page 303.

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. For further information

page 303.

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.

SERVICING AND MAINTENANCE

UTOMATIC

RANSMISSION

Special Additives

It is strongly recommended 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 only the manufacturer's specified

transmission fluid

page 303. 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!

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.

WARNING!

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’s recommended fluid may cause

deterioration in transmission shift quality and/or

torque converter shudder. For fluid

specifications

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.
Also, please be aware that when using power

outlets for extended periods of time with the

engine off may result in vehicle battery discharge.

Blade Fuses

Underhood Fuses

The Power Distribution Center is located in the

engine compartment near the battery. This center

contains cartridge fuses, mini-fuses and relays. A

label that identifies each component is printed on

the inside of the cover.

WARNING!



When replacing a blown fuse, always use an

appropriate replacement fuse with the same

amp rating as the original fuse. Never replace

a fuse with another fuse of higher amp rating.

The use of a fuse with a rating other than indi

cated may result in a dangerous electrical

system overload. If a properly rated fuse

continues to blow, it indicates a problem in the

circuit that must be corrected. Never replace a

blown fuse with metal wires or any other mate

rial. Do not place a fuse inside a circuit

breaker cavity or vice versa. Failure to use

proper fuses may result in serious personal

injury, fire and/or property damage.



Before replacing a fuse, make sure that the

ignition is off and that all the other services

are switched off and/or disengaged.



If the replaced fuse blows again, contact an

authorized dealer.



If a general protection fuse for safety systems

(air bag system, braking system), power unit

systems (engine system, transmission

system) or steering system blows, contact an

authorized dealer.

CAUTION!

If it is necessary to wash the engine

compartment, take care not to directly hit the

fuse box, and the windshield wiper motors with

water.
