276SERVICING AND MAINTENANCE
When inspecting accessory drive belts, small
cracks that run across the ribbed surface of the
belt from rib to rib, are considered normal. This is
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.
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. Use
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.
WINDSHIELD WIPER BLADES
Clean the rubber edges of the wiper blades and the
windshield 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 petroleum products such as engine
oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depending
on geographical area and frequency of use. If chat
-
tering, marks, water lines or wet spots are present,
clean the wiper blades or replace as necessary.

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.
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 the 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.
COOLING SYSTEM
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 see Ú page 239.
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.
CAUTION!
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.

284SERVICING AND MAINTENANCE
AUTOMATIC TRANSMISSION
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.
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.
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.

VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on a label located on the left front
corner of the instrument panel pad, visible from
outside of the vehicle through the windshield.
Windshield VIN Label Location

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems lose
normal capability, the remaining system will still
function. However, there will be some loss of
overall braking effectiveness. You may notice
increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off)
the brakes will still function. However, the effort
required to brake the vehicle will be much greater
than that required with the power system
operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six sided (hex) deep wall
socket.
