Defrost Mode
Air comes from the windshield and side window demist
outlets. Use this setting when necessary to defrost your
windshield and side windows.
NOTE: While operating in either  Auto HI  or  Auto
LO  , the system will not automatically sense the presence of fog, mist, or ice on the windshield.  Defrost  mode
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
conditioning system. When the snowflake symbol
in the ATC display is on, cool, dehumidified air flows
through the air outlets. If economy mode is desired, press
the snowflake button to turn off the snowflake icon in the
ATC display and deactivate the air conditioning system.
Note: While operating in  auto hi  or  auto lo  , the air
conditioning system is always activated. If fog, or mist
appears on the windshield or side glass, select  defrost 
mode and increase blower speed.

the recirculation button. The recirculation mode should
only be used temporarily. The recirculation symbol will
illuminate in the display when this button is selected.
Push the button a second time to turn off the recirculation
icon in the display and allow outside air into the vehicle.
NOTE: In cold weather, use of the Recirculation mode
may lead to excessive window fogging. The Recirculation
mode is not allowed in the Mix and Defrost modes to
improve window clearing operation. Recirculation will
be disabled automatically if these modes are selected.
Rear Automatic Temperature Control — If
Equipped
The Rear Automatic Temperature Control System has
floor air outlets to the rear of the right side sliding door
and overhead outlets at each outboard rear seating
position. The system provides heated air through the
floor outlets or cool, dehumidified air through the head-
liner outlets. The “REAR SYSTEM” knob for the Rear Automatic
Temperature Control System is on the front ATC control
unit located on the instrument panel.
Selecting the “AUTO” position for the Rear Automatic
Temperature Control System from the front ATC control
unit, illuminates a “LOCK” symbol in the rear display.
The rear temperature and air source are controlled from
the front ATC control unit.
The “REAR SYSTEM” knob on the front ATC control unit
has three positions, “REAR CONTROL”, “OFF”, and
“AUTO”. Only when the “REAR SYSTEM” knob is in the
“REAR CONTROL” position do the second seat occu-
pants have control of the Rear Automatic Temperature
Control System.
The Rear Automatic Temperature Control System is
located in the headliner near the center of the vehicle.296 UNDERSTANDING YOUR INSTRUMENT PANEL

glycol antifreeze coolant in water is recommended. Refer
to section 7, Maintenance Procedures, of this manual for
proper coolant selection.
Winter Operation
To insure the best possible heater and defroster perfor-
mance, make sure the engine cooling system is function-
ing properly and the proper amount, type, and concen-
tration of coolant is used. Refer to section 7, Maintenance
Procedures, of this manual for proper coolant selection.
Use of the air Recirculation mode during winter months
is not recommended because it may cause window
fogging.
Vacation Storage
Anytime you store your vehicle, or keep it out of service
(i.e. vacation) for two weeks or more, run the air condi-
tioning system at idle for about five minutes in the fresh
air and high blower setting. This will insure adequate system lubrication to minimize the possibility of com-
pressor damage when the system is started again.
Window Fogging
Vehicle windows tend to fog on the inside in mild rainy
or humid weather. To clear the windows, select  defrost 
or  mix  mode and increase the front blower speed. Do
not use the Recirculation mode without A/C 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.300 UNDERSTANDING YOUR INSTRUMENT PANEL
