Air Conditioner Maintenance
For best possible performance, your air condi -
tioner 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.
Refrigerant Recovery And Recycling —
R-134a — (If Equipped)
R-134a Air Conditioning Refrigerant is a hydro -
fluorocarbon (HFC) that is an ozone-friendly
substance. The manufacturer recommends
that air conditioning service be performed by an
authorized dealer or other service facilities
using recovery and recycling equipment.
NOTE:
Use only manufacturer approved A/C system
PAG compressor oil and refrigerants.
Refrigerant Recovery And Recycling —
R-1234yf — (If Equipped)
R–1234yf Air Conditioning Refrigerant is a
hydrofluoroolefin (HFO) that is endorsed by the
Environmental Protection Agency and is an
ozone-friendly substance with a low
global-warming potential. The manufacturer
1 — Air Cleaner Filter
2 — Air Cleaner Filter Inspection Surface
WARNING!
Use only refrigerants and compressor lubri -
cants approved by the manufacturer for
your air conditioning system. Some unap -
proved 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 information.
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.

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 sepa -
rated 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.
Draining Fuel/Water Separator Filter —
Diesel Engine
There are two fuel filter assemblies. One is
located on the driver's side of the engine. The
best access to this water drain valve is from
under the hood. The second one is on the under
body, located in front of the rear axle above the
drive shaft on pick-up models. The Chassis Cab
models second filter location is on the frame
behind the front axle. The best access to this
water drain valve is from under the vehicle.
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 equipment. If you have any
doubt about your ability to perform a
service job, take your vehicle to a compe
-
tent mechanic.
CAUTION!
Do not drain the fuel/water separator filter
when the engine is running.
Diesel fuel will damage blacktop paving
surfaces. Drain the filter into an appro-
priate container.

Seats And Fabric Parts
Use Mopar Total Clean to clean fabric uphol -
stery and carpeting.
Stain Repel Fabric Cleaning Procedure — If
Equipped
Stain Repel seats may be cleaned in the
following manner:
Remove as much of the stain as possible by
blotting with a clean, dry towel.
Blot any remaining stain with a clean, damp
towel.
For tough stains, apply Mopar Total Clean, or
a mild soap solution to a clean, damp cloth
and remove stain. Use a fresh, damp towel to
remove soap residue.
For grease stains, apply Mopar Multi-Purpose
Cleaner to a clean, damp cloth and remove
stain. Use a fresh, damp towel to remove
soap residue.
Do not use any harsh solvents or any other
form of protectants on Stain Repel products.
Seat Belt Maintenance
Do not bleach, dye or clean the belts with chem -
ical 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 solu -
tion 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.
NOTE:
If the belts retract slowly, inspect the upper
turning loop for soiling. If soiling is present,
clean with a wet soft cloth until all residue is
removed.
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 belt could rip apart in a
collision and leave you with no protection.
Inspect the belt system periodically, checking
for cuts, frays, or loose parts. Damaged parts
must be replaced immediately. Do not
disassemble or modify the system. Seat belt
assemblies must be replaced after a collision
if they have been damaged (i.e., bent
retractor, torn webbing, etc.).
CAUTION!
Direct contact of air fresheners, insect
repellents, suntan lotions, or hand sani -
tizers to the plastic, painted, or decorated
surfaces of the interior may cause perma -
nent damage. Wipe away immediately.
Damage caused by these type of products
may not be covered by your New Vehicle
Limited Warranty.
