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)

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
t o

perform a service job, take your vehicle to a
competent mechanic.

206 SERVICING AND MAINTENANCE
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
com
ponent such as a belt pulley. Belt pulleys
should be carefully inspected for damage and
proper alignment.
Belt replacement on some models requires the
us
e 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 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
t w

ice 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
pe
riods 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
fr
om 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. Poor
performance of blades may be present with chat -
tering, marks, water lines or wet spots. If any of
t h

ese conditions are present, clean the wiper
blades or replace as necessary.

SERVICING AND MAINTENANCE 243
Special Care
If you drive on salted or dusty roads or if you
drive near the ocean, hose off the undercarriage
at least once a month.
It is important that the drain holes in the lower
edges of the doors, rocker panels, and trunk be
kept clear and open.
If you detect any stone chips or scratches in the
paint, touch them up immediately.
If your vehicle is damaged due to a collision or
similar cause that destroys the paint and protec -
tive coating, have your vehicle repaired as soon
a s

possible.
If you carry special cargo such as chemicals,
fertilizers, de-icer salt, etc., be sure that such
materials are well packaged and sealed.
If a lot of driving is done on gravel roads,
consider mud or stone shields behind each
wheel.
Use Mopar® Touch Up Paint on scratches as
soon as possible. An authorized dealer has
touch up paint to match the color of your
vehicle.
INTERIORS
SEATS AND FABRIC PARTS
Use Mopar® Total Clean to clean fabric upholstery
and carpeting.
Seat Belt Maintenance
Do not bleach, dye, or clean the belts with
chemical solvents or abrasive cleaners. This will
weaken the fabric.
If the belts need cleaning, use Mopar® Total
Cl

ean, a mild soap solution, or lukewarm water. Do
not remove the belts from the vehicle to wash
them. Dry with a soft cloth.
Sun damage can also weaken the fabric. Replace
th
e belts if they appear frayed or worn or if the
buckles do not work properly.
PLASTIC AND COATED PARTS
Use Mopar® Total Clean to clean vinyl upholstery.
WARNING!
Do not use volatile solvents for cleaning
purposes. Many are potentially flammable, and
if used in closed areas they may cause
respiratory harm.
WARNING!
A frayed or torn seat belt could rip apart in a col -
lision and leave you with no protection. Inspect
t h
e seat belt system periodically, checking for
cuts, frays, or loose parts. Damaged parts must
be replaced immediately. Do not disassemble or
modify the seat belt system. If your vehicle is
involved in a collision, or if you have questions
regarding seat belt or retractor conditions, take
your vehicle to an authorized FCA dealer or
authorized FCA Certified Collision Care Program
facility for inspection.
CAUTION!
Direct contact of air fresheners, insect repel -
lents, suntan lotions, or hand sanitizers to the
p l
astic, painted, or decorated surfaces of the
interior may cause permanent damage. Wipe
away immediately.
Damage caused by these type of products
may not be covered by your New Vehicle
Limited Warranty.
