Refrigerant Recovery And Recycling
R-134a Air Conditioning Refrigerant is a hydrofluoro-
carbon (HFC) that is endorsed by the Environmental
Protection Agency (EPA) and is an ozone-saving product.
However, the manufacturer recommends that air condi-
tioning service be performed by authorized dealers or
other service facilities using recovery and recycling
equipment.
Front Driveshaft Lubrication – 2500/3500
(Four-Wheel Drive) Models (Ram Trucks Only)
Lubricate the front driveshaft grease fitting at each oil
change. Refer to the “Maintenance Schedule” for the
proper maintenance intervals. Use MOPARType MS-
6560 (lithium-based grease), or equivalent.
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 or equivalent, to assure
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 Fall and Spring. Apply a small
amount of a high quality lubricant, such as MOPAR
Lock Cylinder Lubricant or equivalent directly into the
lock cylinder.

CAUTION!
•Do not use abrasive or strong cleaning materials
such as steel wool or scouring powder which will
scratch metal and painted surfaces.
•Use of power washers exceeding 1,200 psi
(8 274 kPa) can result in damage or removal of
paint and decals.
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. The cost of such repairs is
considered the responsibility of the owner.
•If your vehicle is damaged due to a collision or similar
cause which destroys the paint and protective coating,
have your vehicle repaired as soon as possible. The
cost of such repairs is considered the responsibility of
the owner.
•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 MOPARTouch Up Paint or equivalent on
scratches as soon as possible. Your authorized dealer
has touch up paint to match the color of your vehicle.

Wheel And Wheel Trim Care
All wheels and wheel trim, especially aluminum and
chrome-plated wheels should be cleaned regularly with a
mild soap and water to prevent corrosion. To remove
heavy soil and/or excessive brake dust, use MOPAR
Wheel Cleaner or equivalent or select a nonabrasive,
non-acidic cleaner. Do not use scouring pads, steel wool,
a bristle brush, or metal polishes. Only MOPAR or
equivalent is recommended. Do not use oven cleaner.
Avoid automatic car washes that use acidic solutions or
harsh brushes that may damage the wheels’ protective
finish.

Equipped
Stain Repel seats may be cleaned in the following man-
ner:
•Remove as much of the stain as possible by blotting

•Blot any remaining stain with a clean, damp towel.
•For tough stains, apply MOPAR Total Clean or
equivalent, 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 or equivalent 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.
Interior Care

upholstery and carpeting.
