HEATING & AIR CONDITIONING (Continued)
pressed, the set temp value will become 55 but the
display will show LO. If the set temp is 85 and the
up button is pressed, the set temp value will become
90 but the display will show HIGH. Temperatures
can be displayed in either metric or Fahrenheit,
which is controlled from the overhead console.
• A rocker switch that selects a cool-down rate.
LO-AUTO or HI-AUTO are displayed when the sys-
tem is in automatic operation.
• A defroster button which turns on the defroster
independently during full automatic control. A
defroster symbol illuminates in the display when the
button is pressed.
• Air recirculation button. A Recirculation symbol
appears in the display when the button is pressed, or
when the system exceeds 80 percent circulated air
under automatic control due to high air conditioning
demand.
• Rear window defogger on/off switch. A graphic
symbol shows when the defroster is on.
• An air conditioning button that allows the com-
pressor to be turned off. A Snowflake symbol is illu-
minated when air conditioning is on, whether under
manual or automatic control.
• Rotary knob for front fan speed selection can
override the automatic controls. LEDs surrounding
the knob show the current setting.
• Rotary knob for control of the Rear system.
• A rotary knob for mode control can override the
automatic controls. LEDs surrounding the knob show
the current setting.
• Computer logic remembers the settings of the
controls when the ignition is turned off and retains
those settings after a restart. If the system is off
when the ignition is turned off it will be off when the
engine is restarted, etc.
• Computer logic provides variable air recircula-
tion under high temperature and humidity condi-
tions. Because recirculation is generally accompanied
by increased fan noise, the proportion of recirculated
to outside air gradually approaches full recirculation
over a broad temperature range.
• A graphic symbol of the windshield that illumi-
nates when the windshield wiper deicer is active.
REAR CONTROL PANEL
A rear control panel centrally mounted on the
headliner includes a vacuum-flourescent digital dis-
play, a rocker control for temperature and rotary con-
trols for adjustment of mode and fan speed control of
the rear unit by intermediate seat passengers.
HEATING & AIR CONDITIONING
OPERATION
OPERATION - DUAL ZONE
• The mode control knob enables continously vari-
able proportioning of air flow between modes but has
detents adjacent to each icon.
• The blower control provides five separate speeds.
• When the fan is off, the HVAC computer closes
the recirculation door to prevent outside air from
entering the passenger compartment.
• Interior air may be recirculated to speed up
heating or cooling in all modes except defrost and
mix by pressing the Recirculate button on the control
panel.
• To reduce humidity for rapid defogging the A/C
compressor runs automatically in modes from "mix'
to full defrost when outside temperatures are above
freezing.
• Air conditioning is available in any mode by
pressing the snowflake, A/C on/off, button.
OPERATION - MANUAL THREE ZONE
FRONT CONTROL PANEL
• Primary control of the rear compartment unit is
on the instrument panel. This control allows the
driver to set the rear compartment fan speed, to turn
the rear unit off, or to give control to the intermedi-
ate seat occupants by switching to the REAR posi-
tion. When the rear unit is controlled from the
instrument panel, rear air temperature is based on
the driver-side temperature control position, and the
mode (floor or overhead air) is based on the front
control's mode position.
• The mode control knob enables continously vari-
able proportioning of air flow between modes but has
detents adjacent to each icon.
• The blower control provides five separate speeds
and Off. When the fan is off, the HVAC computer
closes the recirculation door to prevent outside air
from entering the passenger compartment.
• Interior air may be recirculated to speed up
heating or cooling in all modes exccept defrost and
mix by pressing the Recirculate button on the control
panel.
• To reduce humidity for rapid defogging the A/C
compressor runs automatically in modes from "mix'
to full defrost when outside temperatures are above
freezing.
• Air conditioning is available in any mode by
pressing the snowflake, A/C on/off, button.
