mate Control System is ON or OFF. When the blower
control is set to the O (OFF) position the front blower will
turn off and the system will be placed in the Recirculation Manual Air Conditioning and Heating Controls278 UNDERSTANDING YOUR INSTRUMENT PANEL

NOTE: For improved safety, the compressor is activated
and the recirculation mode is deactivated when Mix or
Defrost modes are selected. This is done to assist in
drying the air and it will help in keeping the windows
from fogging.
Manual Air Conditioning Operation
To turn on the air conditioning, set the front
blower control to any position except O (OFF) and
press the A/C button which is located next to the
recirculation button. An indicator light on the A/C

must be manually selected to clear the windshield and
side glass.
The  snowflake  or  a/c  button allows the opera-
tor to manually activate or deactivate the air

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.
NOTE: Use only manufacturer approved A/C System
Sealers, Stop Leak Products, Seal Conditioners, Compres-
sor Oil, or Refrigerants.

towards the center of the car).
Refer to the “Maintenance Schedules” section of 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 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.
