Accessory Drive Belt Inspection
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)
WARNING!
• Do not attempt to inspect an accessory drive belt with
vehicle running.
• When working near the radiator cooling fan, discon-
nect the fan motor lead. The fan is temperature
controlled and can start at any time regardless of igni-
tion 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 equipment. If you have any
doubt about your ability to perform a service job, take
your vehicle to a competent mechanic.

• 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.
Body Lubrication
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 assure 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 Fall and Spring. Apply a small amount of a
high quality lubricant, such as Mopar Lock Cylinder Lubri-
cant directly into the lock cylinder.
Windshield Wiper Blades
Clean the rubber edges of the wiper blades and the wind-
shield periodically with a sponge or soft cloth and a mild
nonabrasive cleaner. This will remove accumulations of salt
or road film.
Operation of the wipers on dry glass for long periods may
cause deterioration of the wiper blades. Always use washer
fluid when using the wipers to remove salt or dirt from a dry
windshield.
Avoid using the wiper blades to remove frost or ice from the
windshield. Keep the blade rubber out of contact with petro-
leum products such as engine oil, gasoline, etc.

518 SERVICING AND MAINTENANCE
NOTE:
Life expectancy of wiper blades varies depending on
geographical area and frequency of use. Poor performance of
blades may be present with chattering, marks, water lines or
wet spots. If any of these conditions are present, clean the
wiper blades or replace as necessary.
The wiper blades and wiper arms should be inspected peri-
odically, not just when wiper performance problems are
experienced. This inspection should include the following
points:
• Wear or uneven edges
• Foreign material
• Hardening or cracking
• Deformation or fatigue
If a wiper blade or wiper arm is damaged, replace the
affected wiper arm or blade with a new unit. Do not attempt
to repair a wiper arm or blade that is damaged.

Exhaust System
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, dete-
riorated, 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 lubrica-
tion or oil change. Replace as required.

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 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.
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 eventu-
ally 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 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! (Continued)

-------------------------------------------------------------------------------------------------------------------------------------------------------------
522 SERVICING AND MAINTENANCE
(Continued)
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
Engine Coolant Checks
Check the engine coolant (antifreeze) protection every
12 months (before the onset of freezing weather, where
applicable). If the engine coolant (antifreeze) is dirty or rusty
in appearance, the system should be drained, flushed and
refilled with fresh coolant. Check the front of the A/C
condenser (if equipped) or radiator for any accumulation of
bugs, leaves, etc. If dirty, clean by gently spraying water
from a garden hose vertically down the face of the A/C
condenser (if equipped) or the back of the radiator core.
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.
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.

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 (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.
NOTE:
• Mixing of engine coolant (antifreeze) other than specified
Organic Additive Technology (OAT) engine coolant (anti-
freeze), may result in engine damage and may decrease
corrosion protection. Organic Additive Technology (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 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 (antifreeze). Use of propylene
glycolbased engine coolant (antifreeze) is not recom-
mended.
• 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 an authorized
dealer.

524 SERVICING AND MAINTENANCE
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 mainte-
nance 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.
• 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 (antifreeze)
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 tempera-
tures 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 authorized
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
an authorized dealer drain, flush, and refill with OAT
coolant (conforming to MS.90032) as soon as possible.
