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 ex-
haust system and adjacent body areas for broken, dam-
aged, 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 lubri-
cation or oil change. Replace as required.

WARNING!

• Exhaust gases can injure or kill. They contain carbon

monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing CO, refer
to “Safety Tips” in “Safety” for further information.

• A hot exhaust system can start a fire if you park over

materials that can burn. Such materials 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 effective-
ness 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 involv-
ing engine misfire or other apparent loss of perfor-
mance, have your vehicle serviced promptly. Contin-
ued operation of your vehicle with a severe
malfunction could cause the converter to overheat,
resulting in possible damage to the converter and
vehicle.

Under normal operating conditions, the catalytic converter
will not require maintenance. However, it is important to
keep the engine properly tuned to assure proper catalyst
operation and prevent possible catalyst damage.

NOTE:

Intentional tampering with emissions control sys-

tems can result in civil penalties being assessed against
you.

472

SERVICING AND MAINTENANCE

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 transmission 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 components

disconnected or removed, such as when diagnostic
testing, or for prolonged periods during very rough idle
or malfunctioning operating conditions.

Cooling System

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 radiator 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, discon-

nect the fan motor lead or turn the ignition to the
OFF mode. The fan is temperature controlled and can
start at any time the ignition is in the ON mode.

Engine Coolant Checks

Check the engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where appli-
cable). If the engine coolant (antifreeze) is dirty, the system
should be drained, flushed, and refilled with fresh OAT
coolant (conforming to MS.90032) by an authorized dealer.
Check the front of the A/C condenser for any accumula-
tion 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 local authorized
dealer.

If the engine coolant (antifreeze) is dirty or contains visible
sediment, have an authorized dealer clean and flush with
OAT coolant (antifreeze) (conforming to MS.90032).

Refer to the “Maintenance Plan” in this section for the
proper maintenance intervals.

Selection Of Coolant

Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.

474

SERVICING AND MAINTENANCE

NOTE:
• Mixing of engine coolant (antifreeze) other than speci-

fied Organic Additive Technology (OAT) engine coolant
(antifreeze), may result in engine damage and may
decrease corrosion protection. Organic Additive Tech-
nology (OAT) engine coolant is different and should not
be mixed with Hybrid Organic Additive Technology
(HOAT) engine coolant (antifreeze) or any “globally
compatible” coolant (antifreeze). If a non-OAT engine
coolant (antifreeze) is introduced into the cooling system
in an emergency, the cooling system will need to be
drained, flushed, and refilled with fresh OAT coolant
(conforming to MS.90032), by an authorized dealer as
soon as possible.

• Do not use water alone or alcohol-based engine coolant

(antifreeze) products. Do not use additional rust inhibi-
tors 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 propyl-

ene glycol-based engine coolant (antifreeze). Use of
propylene glycolbased engine coolant (antifreeze) is not
recommended.

• Some vehicles require special tools to add coolant prop-

erly. 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 your local
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 (anti-
freeze) 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 (antifreeze)
that meets the requirements of FCA Material Standard
MS.90032. When adding engine coolant (antifreeze):
• We recommend using Mopar Antifreeze/Coolant 10

Year/150,000 Mile (240,000 km) Formula OAT (Organic
Additive Technology) that meets the requirements of
FCA Material Standard MS.90032.

8

SERVICING AND MAINTENANCE

475

• Mix a minimum solution of 50% OAT engine coolant

that meets the requirements of FCA 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 (anti-
freeze) 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 prop-

erly. 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 autho-
rized dealer.

• Mixing engine coolant (antifreeze) 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 pos-
sible.

Cooling System Pressure Cap

The cap must be fully tightened to prevent loss of engine
coolant (antifreeze), and to ensure that engine coolant
(antifreeze) will return to the radiator from the coolant
expansion bottle/recovery tank if so equipped.

The cap should be inspected and cleaned if there is any
accumulation of foreign material on the sealing surfaces.

WARNING!

• Do not open hot engine cooling system. Never add

engine coolant (antifreeze) when the engine is over-
heated. 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 speci-

fied for your vehicle. Personal injury or engine
damage may result.

476

SERVICING AND MAINTENANCE

Disposal Of Used Coolant

Used ethylene glycol-based coolant (antifreeze) is a regu-
lated 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 contain-
ers 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 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 (antifreeze) 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 (antifreeze) is needed to
maintain the proper level, only OAT coolant that meets the
requirements of FCA Material Standard MS.90032 should
be added to the coolant bottle. Do not overfill.

Points To Remember

NOTE:

When the vehicle is stopped after a few miles/

kilometers 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 (anti-
freeze) 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 (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.

• If frequent engine coolant (antifreeze) additions are

required, the cooling system should be pressure tested
for leaks.

SERVICING AND MAINTENANCE

477

• Maintain engine coolant (antifreeze) concentration at a

minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.

• 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 necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.

Brake System

In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.

WARNING!

Riding the brakes can lead to brake failure and possi-
bly 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.

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.

Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.

478

SERVICING AND MAINTENANCE

WARNING!

• Use only manufacturer’s recommended brake fluid.

Refer to “Fluids And Lubricants” in “Technical
Specifications” for further information. 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 mois-

ture, use only new brake fluid or fluid that has been
in a tightly closed container. Keep the master cylin-
der 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 brak-
ing, 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.

(Continued)

WARNING! (Continued)

• Do not allow petroleum based fluid to contaminate

the brake fluid. Brake seal components could be
damaged, causing partial or complete brake failure.
This could result in a collision.

Automatic Transmission

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. Refer
to “Fluids And Lubricants” in “Technical Specifications”
for fluid specifications. It is important to maintain the
transmission fluid at the correct level using the recom-
mended fluid.

NOTE:

No chemical flushes should be used in any trans-

mission; only the approved lubricant should be used.

SERVICING AND MAINTENANCE

479

CAUTION!

Using a transmission fluid other than the manufactur-
er’s recommended fluid may cause deterioration in
transmission shift quality and/or torque converter
shudder. Refer to “Fluids And Lubricants” in “Techni-
cal Specifications” for fluid specifications.

Special Additives

The manufacturer strongly recommends against using any
special additives in the transmission. Automatic Transmis-
sion Fluid (ATF) is an engineered product and its perfor-
mance may be impaired by supplemental additives. There-
fore, do not add any fluid additives to the transmission.
Avoid using transmission sealers as they may adversely
affect seals.

CAUTION!

Do not use chemical flushes in your transmission as
the chemicals can damage your transmission compo-
nents. Such damage is not covered by the New Vehicle
Limited Warranty.

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 transmis-
sion 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 im-
proper fluid level can cause severe transmission damage.

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.

SERVICING AND MAINTENANCE

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 contami-
nated (with water, etc.), or if the transmission is disas-
sembled for any reason.
