The Air Conditioning and Heating System is designed to
make you comfortable in all types of weather. The
following describes its operation:
Air Conditioning Operation
To turn the air conditioning On or Off perform the
following steps:
•Position the mode control button to the desired airflow
setting.
•Set the front blower control to any desired speed.
•Press the Snowflake (A/C) button which is located to
the right of the temperature control slide. An indicator
light on the Snowflake (A/C) button shows that the air
conditioning is On.
•Press the Snowflake (A/C) button a second time to
turn the air conditioning Off.
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.
Front Blower Control
The Front Blower controls the
amount of air delivered to the
passenger compartment.
There are four blower speeds.
The fan speed increases as
you turn the control clock-
wise. When the front blower
control is turned to OFF, the
blower will be turned off and
the system will be positioned
in recirculation mode.
Front Mode Control
The mode control allows you to
choose from several patterns of air
distribution.
NOTE:To improve your selection choices, the system
allows you to operate at intermediate positions between
the major modes. These intermediate positions are iden-
tified by the small dots and give an even blend of both
modes.

located in the overhead console to measure the tem-
perature of the driver and passengers. Based on the
sensor input, the system will automatically ocntrol
comfort by varying the temperature, fan speed, and
mode. This maintains a comfortable temperature, even
under changing conditions. It is important that objects
are not blocking the infrared sensor. It is also impor-
tant that objects are not used that may scratch or
damage it in any way.
Level Of Automatic Control
72°F (22°C) is the recommended setting for maximum
comfort for the average person, however, this may vary.
NOTE:The temperature setting can be adjusted at any
time without affecting automatic control operation. It is
not necessary to move the temperature setting for cold or
hot vehicles. The system automatically adjusts the tem-
perature, mode and fan speed to provide comfort as
quickly as possible.NOTE:In cold weather, the fan will not turn on in
AUTO mode until the engine coolant has warmed up
sufficiently. This is indicated by the WARM UP DELAY
message on the display.
NOTE:The temperature can be displayed in U.S. or
Metric by selecting the US/M customer programmable
feature. Refer to theOverhead Console-Customer Pro-
grammable Features.The mode will also be shown in the
display and will change as required during automatic
operation.
NOTE:The system can be put into recirculate mode
without affecting ATC operation. This will prevent out-
side air from entering the vehicle. Use this mode to
temporarily block out any outside odors, smoke, or dust.

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.
FAN Control
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.

If the rear wiper is operating when the ignition is turned
off, the wiper will automatically return to the “Park”
position. When the vehicle is restarted, the wiper will
resume operation.
Rear Window Defrosting
A push-button type switch is located in the climate
control panel. Press the switch and the rear win-
dow defroster and electric remote control heated mirrors
(if equipped) will turn On. An amber indicator on the
push-button will light when the defroster is turned On.
An symbol will be displayed when the defroster is turned
on with an ATC control. Push again to turn Off prior to
time-out. The defroster will automatically turn Off after
fifteen minutes. For ten more minutes of operation, push
the button again. To prevent excessive battery drain, use
the defroster only when the engine is operating.
CAUTION!
Use care when washing the inside of the rear win-
dow to prevent damage to heating elements. Use a
soft cloth and a mild washing solution, wiping
parallel to the heating elements. Also, keep all
objects a safe distance from the window to prevent
damaging the heating elements.
