WARNING!• Use only refrigerants and compressor lubricants
approved by the manufacturer for your air condi-
tioning 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 Section 3 of the Warranty Information book for
further warranty information.
• 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 repairman. Refrigerant Recovery and Recycling
R-134a Air Conditioning Refrigerant is a hydrofluorocar-
bon (HFC) that is endorsed by the Environmental Pro-
tection Agency and is an ozone-saving product. How-
ever, the manufacturer recommends that air conditioning
service be performed by dealers or other service facilities
using recovery and recycling equipment.
Power Steering — Fluid Check
Checking the power steering fluid level at a defined
service interval is not required. The fluid should only be
checked if a leak is suspected, abnormal noises are
apparent, and/or the system is not functioning as antici-
pated. Coordinate inspection efforts through a certified
DaimlerChrysler Dealership.  MAINTAINING YOUR VEHICLE 421

WARNING!Fluid level should be checked on a level surface and
with the engine off to prevent injury from moving
parts and to insure accurate fluid level reading. Do
not overfill. Use only manufacturers recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from all
surfaces. Refer to Fluids, Lubricants, and Genuine Parts
for correct fluid type.
Front Suspension Ball Joints
The ball joints originally supplied with the vehicle are
permanently lubricated at the factory and do not require
service. The ball joints and seals should be inspected
whenever the vehicle is serviced for other reasons. Steering Linkage — Inspection
Whenever the vehicle is hoisted, all steering linkage
joints should be inspected for evidence of damage. If
seals are damaged, parts should be replaced to prevent
leakage or contamination of the grease.
Front Prop Shaft Lubrication
Lubricate the front driveshaft grease fitting at each oil
change listed in the appropriate Maintenance Schedule
for your vehicle (Schedule “A” and “B”). Use Mopar 
type MS-6560 (lithium based grease), or equivalent.422 MAINTAINING YOUR VEHICLE

Brake System
Power Disc Brakes (Front and Rear)
Disc brakes do not require adjustment; however, several
hard stops during the break-in period are recommended
to seat the linings and wear off any foreign material.
Brake And Power Steering Hoses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,
cracking, tears, cuts, abrasion, and excessive swelling
indicate deterioration of the rubber. Particular attention
should be made to examining those hose surfaces nearest
to high heat sources, such as the exhaust manifold.
Insure nylon tubing in these areas has not melted or
collapsed. Inspect all hose connections such as clamps and cou-
plings to make sure they are secure and no leaks are
present.
NOTE: Often, fluid such as oil, power steering fluid,
and brake fluid are used during assembly plant opera-
tions to facilitate the assembly of hoses to couplings.
Therefore, oil wetness at the hose-coupling area is not
necessarily an indication of leakage. Actual dripping of
hot fluid when systems are under pressure (during
vehicle operation), should be noted before hose is re-
placed based on leakage.
NOTE: Inspection of brake hoses should be performed
whenever the brake system is serviced and every engine
oil change. Inspect hydraulic brake hoses for surface
cracking, scuffing, or worn spots. If there is any evidence
of cracking, scuffing, or worn spots, the hose should be
replaced immediately! Eventual deterioration of the hose
can take place resulting in a possibility of a burst failure.434 MAINTAINING YOUR VEHICLE

• Check the windshield washer solvent and add if
required. When refilling the washer fluid reservoir,
take some washer fluid and apply it to a cloth or towel
and wipe clean the wiper blades, this will help blade
performance.
Once a Month
• Check tire pressure and look for unusual wear or
damage.
• Inspect the battery and clean and tighten the terminals
as required.
• Check the fluid levels of coolant bottle, brake master
cylinder, and transmission and add as needed.
• Check all lights and all other electrical items for correct
operation. At Each Oil Change
• Change the engine oil filter.
• Lubricate Drivetrain/Steering/Suspension Grease Fit-
tings (if equipped)
• Inspect the exhaust system.
• Inspect the brake hoses.
• Inspect the CV joints/U— joints (if equipped) and
front suspension components.
• Check the automatic transmission fluid level.
• Check the manual transmission fluid level.
• Check the coolant level, hoses, and clamps.
• Lubricate Front Drive Shaft Fitting (4X4).486 MAINTENANCE SCHEDULES
