NSPECTION

When inspecting accessory drive belts, small

cracks that run across ribbed surface of belt from

rib to rib, are considered normal. These are not a

reason to replace belt. However, cracks running

along a rib (not across) are not normal. Any belt

with cracks running along a rib must be replaced.

Also have the belt replaced if it has excessive wear,

frayed cords or severe glazing.

Accessory Belt (Serpentine Belt)

Conditions that would require replacement:



Rib chunking (one or more ribs has separated

from belt body)



Rib or belt wear



Longitudinal belt cracking (cracks between two

ribs)



Belt slips



“Groove jumping" (belt does not maintain

correct position on pulley)



Belt broken (note: identify and correct problem

before new belt is installed)



Noise (objectionable squeal, squeak, or rumble

is heard or felt while drive belt is in operation)

Some conditions can be caused by a faulty

component such as a belt pulley. Belt pulleys

should be carefully inspected for damage and

proper alignment.

Belt replacement on some models requires the

use of special tools, we recommend having your

vehicle serviced at an authorized dealer.

ODY

UBRICATION

Locks and all body pivot points, including such

items as seat tracks, door hinge pivot points and

rollers, liftgate, tailgate, decklid, sliding doors and

hood hinges, should be lubricated periodically with

a lithium-based grease, such as Mopar® Spray

White Lube to ensure quiet, easy operation and to

protect against rust and wear. Prior to the

application of any lubricant, the parts concerned

should be wiped clean to remove dust and grit;

after lubricating excess oil and grease should be

removed. Particular attention should also be given

to hood latching components to ensure proper

function. When performing other underhood

services, the hood latch, release mechanism and

safety catch should be cleaned and lubricated.
The external lock cylinders should be lubricated

twice a year, preferably in the Autumn and Spring.

Apply a small amount of a high quality lubricant,

such as Mopar® Lock Cylinder Lubricant directly

into the lock cylinder.

WARNING!



Do not attempt to inspect an accessory drive

belt with vehicle running.



When working near the radiator cooling fan,

disconnect the fan motor lead. The fan is

temperature controlled and can start at any

time regardless of ignition mode. You could be

injured by the moving fan blades.



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

ment. If you have any doubt about your ability

to perform a service job, take your vehicle to a

competent mechanic.

XHAUST

YSTEM

The best protection against carbon monoxide entry

into the vehicle body is a properly maintained

engine exhaust system.
If you notice a change in the sound of the exhaust

system; or if the exhaust fumes can be detected

inside the vehicle; or when the underside or rear of

the vehicle is damaged; have an authorized

technician inspect the complete exhaust system

and adjacent body areas for broken, damaged,

deteriorated, or mispositioned parts. Open seams

or loose connections could permit exhaust fumes

to seep into the passenger compartment. In

addition, have the exhaust system inspected each

time the vehicle is raised for lubrication or oil

change. Replace as required.

SERVICING AND MAINTENANCE

(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.

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

page 305.



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.

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.

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

page 335.

Selection Of Coolant

Refer to Engine Fluids And Lubricants

page 405.

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.

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



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.
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.



Use care when filling under hood fluids such as

engine oil, washer fluid, antifreeze, etc., to mini

mize spillage onto the top of the engine. Any

excess fluid that is spilled onto the top of the

engine should be removed using compressed

air or an absorbent cloth.



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 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.

WARNING!



Do not open a 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.

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 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

bottle need only 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.

Engine Coolant Level — 2.0L

With the engine OFF and cold, the level of the

engine coolant should be within the OK range

between the ADD and FULL range on the dipstick.
1. Remove the cap with level dipstick from the

engine coolant bottle.

2. Clean off the coolant from the dipstick.
3. Rest the cap on the opening of the coolant

bottle without tightening the cap.

4. Remove the cap with dipstick and check the

coolant level on the dipstick.

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

bottle need only 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.

WARNING!



Do not open a 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.

356

SERVICING AND MAINTENANCE

(Continued)

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.

YSTEM

In order to ensure brake system performance, all

brake system components should be inspected

periodically. For the proper maintenance intervals

page 335.

Fluid Level Check — Brake Master Cylinder

The fluid level of the 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.

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

page 406. 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.

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 only the manufacturer's specified

transmission fluid

page 406. 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.



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 contam

inate the brake fluid. Brake seal components

could be damaged, causing partial or

complete brake failure. This could result in a

collision.

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.

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 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 (PDC) is located on

the passenger side of the engine compartment,

behind the headlamp. This center contains

cartridge fuses, micro fuses, relays, and circuit

breakers. A description of each fuse and

component may be stamped on the inside cover,

otherwise the cavity number of each fuse is

stamped on the inside cover that corresponds to

the following chart.

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.
