AUTOMATIC AIR CONDITIONING SYSTEM
M MECHANISM AND FUNCTION
1 . Outline
1 . The outlet air temperature, outlet air flow, intake port
mode and outlet port mode are automatically selectable
so as to provide comfortable air conditioning at all times
of the year .
2 . In addition to the AUTO switch, a manual switch is
provided for selecting the outlet air flow (3 steps), outlet
mode (VENT and DEF), intake port (RECIRC for 10
minutes) and economy mode (Compressor OFF).
3. The compressor is a wobble, variable delivery type .
It is electronically controlled by way of communication
between the MPFI unit and the A/C auto amplifier to
increase driving ability as well as power-saving, cool-
down and dehumidifying performance.
4 . The push-button type control panel features im-
proved ergonomic design.
5. The side defroster outlet port is located in the door
trim area . This arrangement reduces dust from entering
the door window, and improves side mirror visibility .
6. A large, specialized air outlet is provided on the rear
side of the rear bumper to improve ventilation effi-
ciency .
7. The auto amplifier has a self-diagnosis function,
which allows easy trouble-diagnosis. An air outlet tem-
perature correcting function is added which corrects for
external temperature, depending on the temperature
requirements of the passengers .
8 . An electric cooling fan is used with three settings
(LOW, MEDIUM, HIGH), which reduces noise and en-
ergy.
9 . To improve the accelerating performance of the
vehicle, the compressor stops when the accelerator is
moved to the full throttle position .
10 . The sunload sensor features high sensitivity to
sunlight from both vertical and horizontal directions .
11 . All A/C system components are designed to in-
crease efficiency, and delivery- and refrigerant-saving
performance, as well as to reduce weight .
