Defrost
Outside air is primarily directed to the windshield
through the defroster outlet located at the base of
the windshield and side window demist outlets.
NOTE:The air conditioning compressor operates in
both Mix and Defrost or a blend of these modes, even if
the A/C button has not been pressed. This dehumidifies
the air to help dry the windshield.

The temperature of the air is controlled by a slide located
on the top center of the control panel. Move the slide left
or right to change the temperature. The blue area of the
scale indicates cooler temperatures while the red area
indicates warmer temperatures.

Manual Control (ATC)
You also may choose to customize your comfort by
selecting the fan speed and mode manually. Turning the
fan speed knob or any mode button places the system
into manual operation.
While in manual operation there are six fan speeds
available and the choice of any mode. The airflow
temperature is adjusted automatically to maintain the
desired comfort level. You can adjust the temperature by
pressing the + or - TEMP rocker switches.

Use this knob to regulate the amount of air delivered
through the system in any mode you select. Rotation
of the knob to increase (clockwise) or decrease (counter-
clockwise) fan speed.
Air Conditioning Operation
Press this button to enable the air conditioning
system. Compressor operation is automatic when
you press the AUTO button and no snowflake is
shown. A snowflake indicates that the A/C system is
enabled. The snowflake will not be displayed in AUTO
mode even though the A/C system is enabled.
The compressor may operate at any temperature above
32°F (0°C).
NOTE:The compressor will not engage until the engine
has been running for several seconds. Slight changes in
engine speed or power may be noticed when the com-
pressor cycles. This is a normal occurrence since the
compressor will cycle on and off to maintain comfort and
improve fuel economy.
240 INSTRUMENT PANEL AND CONTROLS

Bi-Level
Air flows through the outlets located in the instru-
ment panel and those located on the floor.
NOTE:There is a difference in temperature between the
upper and lower outlets for added comfort. The warmer
air goes to the floor outlets. This feature gives improved
comfort during sunny but cool conditions.
Defrost
Outside air is directed to the windshield through
the defroster outlet located at the base of the
windshield and side window demist outlets.
NOTE:The air conditioning compressor operates in
both Mix and Defrost or a blend of these modes, even if
the A/C snowflake button has not been pressed. This
dehumidifies the air to help dry the windshield.
Rear Temperature Control (ATC)
The “REAR” button cycles through the following modes:
Rear Control from Front
This allows the driver or passenger to control the rear
blower speeds rotating the POWER / FAN knob and the
rear temperature using the pass/rear TEMP +/- rocker
switch. While in this mode, pressing the POWER/FAN
knob will turn the rear system off. Pressing the POWER/
FAN knob will turn the rear system back on.

Rear Zone Climate Control — If Equipped
Headliner air comes from the outlets in the headliner.
Each of these outlets can be individually adjusted to
direct the flow of air. Moving the air vane knobs on the
outlets to one side will shut off the airflow.The rear compartment control uses two rotary knobs: one
for the temperature control and the other for the fan
speed control. The mode for the rear air conditioning and
heating system is always controlled by the front control
unit. Fan and temperature can be controlled from the
front control unit or the rear control unit.

Operating Tips
Fast Cooldown
For a fast cooldown, set the blower fan to the highest
setting, set the mode control to the panel fresh position,
press the snowflake button to turn on the air condition-
ing, and drive with the windows open for the first few
minutes. Once the hot air has been expelled, close the
windows and set the mode selector to the Recirculation
panel or Recirculation Bi-level position. When a comfort-
able condition has been reached, choose a mode positionand adjust the temperature control and blower speed as
necessary to maintain comfort. For high humidity condi-
tions it may be necessary to remain in the Recirculation
mode to maintain comfort.
Window Fogging
Windows will fog on the inside when the humidity inside
the vehicle is high. This often occurs in mild or cool
temperatures when it’s rainy or humid. In most cases
turning on the Air-conditioning (pressing the snowflake
button) will clear the fog. Adjust the temperature control,
air direction and blower speed to maintain comfort.
As the temperature gets colder it may be necessary to
direct air onto the windshield by using MIX Mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. Interior fogging
on the windshield can be quickly removed by selecting
the defrost mode.

CAUTION!
•It is essential when replacing the cables on the
battery that the positive cable is attached to the
positive post and the negative cable is attached to
the negative post. Battery posts are marked (+)
positive and negative (-) and identified on the
battery case.
•If a “fast charger” is used while battery is in
vehicle, disconnect both vehicle battery cables
before connecting the charger to battery. Do not
use a “fast charger” to provide starting voltage.
Air Conditioner Maintenance
For best possible performance, your air conditioner should
be checked and serviced by an Authorized Dealer at the
start of each warm season. This service should include
cleaning of the condenser fins and a performance test.
Drive belt tension should also be checked at this time.
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.
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 and seals should be inspected whenever
the vehicle is serviced for other reasons. Damaged seals
should be replaced to prevent leakage or contamination
of the grease.
