system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
Window Fogging
Interior fogging on the windshield can be quickly re-
moved by turning the mode selector to Defrost. The
Defrost/Floor mode can be used to maintain a clear
windshield and provide sufficient heating. If side win-
dow fogging becomes a problem increase blower speed.
Vehicle windows tend to fog on the inside in mild but
rainy or humid weather.
NOTE:Recirculate without A/C should not be used for
long periods as fogging may occur.
Outside Air Intake
Make sure the air intake, located directly in front of the
windshield, is free of obstructions such as leaves. Leaves
collected in the air intake may reduce airflow, and if they
enter the plenum, they could plug the water drains. In
winter months, make sure the air intake is clear of ice,
slush, and snow.
A/C Air Filter — If Equipped
The climate control system filters outside air containing
dust, pollen and some odors. Strong odors cannot be
totally filtered out. Refer to “Maintenance Procedures” in
Section 7 of this manual for filter replacement instruc-
tions.

Engine Air Cleaner Filter
For normal driving conditions, inspect and replace the
engine air cleaner filter at the intervals shown on Sched-
ule “A.” For vehicles driven frequently in dusty or under
severe conditions, inspect and replace the engine air
cleaner filter at the intervals shown on Schedule “B.”
WARNING!
The air induction system (air cleaner, hoses, etc) can
provide a measure of protection in the case of engine
backfire. Do not remove the air induction system (air
cleaner, hoses, etc) unless such removal is necessary
for repair or maintenance. Make sure that no one is
near the engine compartment before starting the
vehicle with the air induction system (air cleaner,
hoses, etc) removed. Failure to do so can result in
serious personal injury.
Fuel Filter
A plugged fuel filter can cause stalling, limit the speed at
which a vehicle can be driven or cause hard starting.
Should an excessive amount of dirt accumulate in the
fuel tank, filter replacement may be necessary. See your
local dealer for service.
Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.

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 technician.
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.
NOTE:Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, and Refrigerants.
A/C Air Filter — If Equipped
The filter is located in the fresh air inlet under the hood,
behind a removable panel in the cowl on the passenger
side of the vehicle, next to the windshield wipers. When
installing a new filter, ensure its proper orientation. To
replace the filter remove the access door in the cowl
screen by pressing the retaining clips. Slide the lid on the
filter adapter forward and down and remove used filter.
Install new filter with arrows pointing in the direction of
airflow, which is toward the rear of the vehicle (text and
arrows on the filter indicate this).

Refer to the “Maintenance Schedule” in this manual for
the recommended air conditioning filter replacement
intervals.
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.
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 manufacturer’s recommended
power steering fluid.
If necessary, add fluid to restore to the proper indicated
level. With a clean cloth, wipe any spilled fluid from allsurfaces. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the correct fluid type.
Front & Rear Suspension Ball Joints
The suspension ball joints should be inspected for exter-
nal leakage or damage when other maintenance is per-
formed.
Steering Linkage
The tie rod end ball joints should be inspected for
external leakage or damage when other maintenance is
performed.
Body Lubrication
Locks and all body pivot points, including seat tracks,
door hinges, trunk hinges, and hood hinges, should be
lubricated periodically to assure quiet, easy operation
and to protect against rust and wear. Prior to the appli-
cation 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 insure proper function. When performing other
underhood services, the hood latch, release mechanism,
and safety catch should be cleaned and lubricated.

CAUTION!
•Using a transmission fluid other than the manu-
facturer’s recommended fluid may cause deterio-
ration in transmission shift quality and/or torque
converter shudder. Using a transmission fluid
other than that recommended by the manufac-
turer will result in more frequent fluid and filter
changes. Refer to “Fluids, Lubricants, and Genu-
ine Parts” for the correct fluid type.
•The fluid level is preset at the factory and it does
not require adjustment under normal operating
conditions. If a transmission fluid leak occurs,
visit your authorized dealer immediately. Severe
damage to the transmission may occur. Your au-
thorized dealer has the proper tools to adjust the
fluid level accurately.
Fluid and Filter Changes
Automatic transmission fluid and filter should be
changed as follows:
Normal Usage — No change necessarySevere Usage (fluid and filter) — Refer to Maintenance
Schedule “B”
Severe Usage is defined as:
•Police, taxi, limousine, commercial type operation, or
trailer towing where the vehicle is drivenregularlyfor
more than 45 minutes of continuous operation.
If the transmission is disassembled for any reason, the
fluid and filter should be changed.
Special Additives
Automatic Transmission Fluid (ATF) is an engineered
product and its performance may be impaired by supple-
mental additives. Therefore, do not add any fluid addi-
tives to the transmission. The only exception to this
policy is the use of special dyes to aid in detecting fluid
leaks. In addition, avoid using transmission sealers as
they may adversely affect seals.
Front and Rear Wheel Bearings
Front and rear wheel bearings are permanently sealed.
No regular maintenance is required for these compo-
nents.
