FIG. 2-16: AIR CONDITIONING CONTROLS
Automatic Climate
Control
The Automatic Climate Control air condi¬
tioning system controls heating and air condi¬
tioning automatically to maintain comfort in
the passenger compartment. With the controls
set for heating or air conditioning, the system
turns on automatically and controls the vol¬
ume and temperature of the air discharged
through the dash and heater outlets.
Controls—The control panel (located
below left dash outlet, Fig. 2-16) is illuminated
when instrument panel lights are on. The
temperature dial is color coded for quick re¬
ference to the interior temperature selected.
The white area of the dial includes those
temperatures normally considered comforta¬
ble. The red and blue areas respectively in¬
clude the warmer and cooler temperature set¬
tings.
INITIAL SETTINGS
• Set color coded temperature dial to de¬
sired in-car temperature.
• Set control lever to desired type of system
operation.
• Direct the dash outlets by rolling the out¬
let up or down, or aiming the vanes side¬
ways in the direction of desired airflow.
• Dash outlets may be individually shut off
by moving the control knob (below the
outlet) forward, Fig. 2-17.
CONTROL LEVER POSITIONS
"OFF"—The compressor is disengaged, but
the air conditioner blower will operate at a
low speed for ventilation. All air will be deli¬
vered from the heater outlet.
VENTILATION AND HEATING
"ECONOMY"—I n th i s setti ng the ai r cond i -
tioning compressor does not operate and the
reduced engine load will result in improved
fuel economy.
Use this setting for heating in cold weather
to conserve fuel. In mild weather, set the
temperature dial about 5° cooler than usual.
The blower operates automatically at varying
speeds. Temperature control will be provided
to maintain the car interior at approximately
the temperature set on the dial. Air will be
delivered from the dash outlets in warmer
weather. At lower temperatures, air will be
delivered from the underdash outlet only.
