NOTE:Inspect and clean the housing assembly if signif
-
icant dirt or debris is present before replacing the
engine air cleaner filter.

1. Install the engine air cleaner filter into the housing assembly with the engine air cleaner
filter inspection surface facing downward.

2. Install the engine air cleaner filter cover onto the housing assembly locating tabs.
3. Tighten the fasteners on the engine air cleaner filter assembly.
AIR CONDITIONER MAINTENANCE
For best possible performance, your air conditioner
should be checked and serviced by an authorized
dealer at the start of each warm season. This
service should include cleaning of the condenser
fins and a performance test. Drive belt tension
should also be checked at this time.
1 — Engine Air Cleaner Filter Cover
2 — Fasteners
CAUTION!
Do not overtighten the engine air cleaner filter
cover lid screws or damage may result.
WARNING!
Use only refrigerants and compressor lubri
-
cants approved by the manufacturer for your
air conditioning system. Some unapproved
refrigerants are flammable and can explode,
injuring you. Other unapproved refrigerants or
lubricants can cause the system to fail,
requiring costly repairs. Refer to Warranty
Information Book, for further warranty infor -
mation.
The air conditioning system contains refrig -
erant under high pressure. To avoid risk of
personal injury or damage to the system,
adding refrigerant or any repair requiring lines
to be disconnected should be done by an
experienced technician.
CAUTION!
Do not use chemical flushes in your air
conditioning system as the chemicals can
damage your air conditioning components. Such
damage is not covered by the New Vehicle
Limited Warranty.

Cabin Air Filter Cover

6. Remove the cabin air filter by pulling it straight out of the housing.
7. Install the cabin air filter with the arrow on the filter pointing toward the floor. When installing
the filter cover, make sure the retaining tabs
fully engage into the HVAC housing. 8. Lift the glove compartment door up and
reattach the tension tether by inserting the
tether clip in the glove compartment and
sliding the clip away from the face of the glove
compartment door.
9. Push the door to the near closed position to reengage the glove compartment travel stops.
NOTE:Ensure the glove compartment travel stops are
fully engaged.
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)
1 — Retaining Tabs
CAUTION!
The cabin air filter is identified with an arrow to
indicate airflow direction through the filter.
Failure to properly install the filter will result in
the need to replace it more often.
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.

23_WL_OM_EN_USC_t.book Page 342

SERVICING AND MAINTENANCE343
Belt broken (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 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. Poor
performance of blades may be present with chat
-
tering, 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 periodically, 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.
Front Wiper Blade Removal/Installation
CAUTION!
Do not allow the wiper arm to spring back
against the glass without the wiper blade in
place or the glass may be damaged.

394SERVICING AND MAINTENANCE
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. Sun damage can also weaken the fabric.
If the belts need cleaning, use a mild soap solution
or lukewarm water. Do not remove the belts from
the vehicle to wash them. Dry with a soft cloth.
Replace the 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
collision and leave you with no protection.
Inspect the 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
plastic, 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.
