WARNING!(Continued)
•The air conditioning system contains refrigerant
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.
Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by authorized dealer or other
service facilities using recovery and recycling equipment.
NOTE: Use only manufacturer approved A/C system
sealers, stop leak products, seal conditioners, compressor
oil, and refrigerants.
Body Lubrication
Locks and all body pivot points, including such items as
seat tracks, door hinge pivot points and rollers, liftgate,
tailgate, sliding doors and hood hinges, should be lubri-
cated periodically with a lithium based grease, such as
MOPAR Spray White Lube to assure quiet, easy opera-
tion 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 compo-
nents 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 Lubricant directly into the lock cylinder.

Wiper Blades
Clean the rubber edges of the wiper blades and the
windshield and rear window periodically with a sponge
or soft cloth and a mild nonabrasive cleaner. This will
remove accumulations of salt, waxes, or road film, and
help reduce streaking and smearing.
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 or rear window.
Avoid using the wiper blades to remove frost or ice from
the windshield or rear window. Make sure that they are
not frozen to the glass before turning them on to avoid
damaging the blade. Keep the blade rubber out of contact
with petroleum products such as engine oil, gasoline, etc.
NOTE:Life expectancy of wiper blades varies depend-
ing 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 neces-
sary.
Adding Washer Fluid
The windshield washer fluid reservoir is located in the
front of the engine compartment on the passenger side of
the vehicle. Be sure to check the fluid level in the
reservoir at regular intervals. Fill the reservoir with
windshield washer solvent (not engine coolant (anti-
freeze) and operate the system for a few seconds to flush
out the residual water.
WARNING!
Commercially available windshield washer solvents
are flammable. They could ignite and burn you. Care
must be exercised when filling or working around
the washer solution.

manufacturer’s recommended brake fluid. Refer to “Flu-
ids, Lubricants, and Genuine Parts” in “Maintaining Your
Vehicle” for further information.
Rear Axle
Axle Lubricant Level Check
Check the exterior of the axle for evidence of gear oil
leakage every 12 months or 6,000 miles (10 000 km). This
check should be made with the vehicle level and on the
ground or raised on an axle and wheel type hoist. The
axle lubricant level should be between the bottom of the
filler plug and a point approximately 3/8 inch (9.5 mm)
below the filler plug. If adding axle lubricant, use only
the manufacturer’s recommended axle lubricant. Refer to
“Fluids, Lubricants, and Genuine Parts” in “Maintaining
Your Vehicle” for further information.
CAUTION!
Using axle fluid other than the manufactured recom-
mended fluid may cause a shudder/noise issue. refer
to “Fluids Lubes and Genuine Parts” in “ Maintain-
ing Your Vehicle” for further information.
Change Axle Lubricant
Refer to “Maintenance Schedule” for the proper mainte-
nance intervals. Change the lubricant immediately if
contaminated with water. See your authorized dealer for
service.
Appearance Care And Protection From Corrosion
Protection Of Body And Paint From Corrosion
Vehicle body care requirements vary according to geo-
graphic locations and usage. Chemicals that make roads
passable in snow and ice, and chemicals that are sprayed
on trees and road surfaces during other seasons, are
