FORCED DEF CONTROL
When air outlet position is switched to DEF, A/C is
automatically turned ON, and outside/inside air
selection damper is set to the fresh air position to
quickly defrost the windshield screen.
.
MAX A/C CONTROL
When the temperature adjustment knob is turned to
the maximum A/C position with the blower knob at
position other than OFF, the following controls are
made by the A/C-ECU.
NOTE: "*" Manual operation is disabled during max
A/C control.
.
MAX COOL, MAX HOT CONTROL

When the set temperature is at 18.0 °C <61°F>
(MAX COOL) or at 32.0
°C <89°F> (MAX HOT) with
the air outlet and air volume at the AUTO positions,
the following controls are made automatically by the
A/C-ECU.
NOTE: "*" indicates that when the automatic control
is not cancelled using the customise function, the
manual operation is disabled.
.
REAR WINDOW DEFOGGER TIMER
CONTROL
In order to prevent battery consumption, the defog-
ger is automatically turned OFF, 20 minutes after it is
turned ON.
.
IDLE-UP CONTROL
A/C-ECU and the engine ECU communicate with
each other through the CAN communication. The
idle-up speed of the engine is controlled in two steps
depending on the A/C load to secure the air cooling
performance during summer and to enhance fuel
economy in seasons with moderate temperature.
.
DETECTION CONTROL FOR
REFRIGERANT LEAKS
A/C-ECU determines if the refrigerant amount is less
than specified or refrigerant pressure is abnormal by
using the ambient temperature (ambient temperature
sensor to measure refrigerant inflation rate) and
refrigerant pressure (measured by the A/C pressure
sensor). When refrigerant amount or refrigerant pres
-
sure is judged abnormal, the compressor is cut-off to
protect the A/C system.
NOTE: When abnormality occurs, the A/C indicator
flashes.
.
PROTECTION CONTROL AT AIR BAG
DEPLOYMENT (DURING COLLISION)
When the air bag deployment is detected, the A/C
system is stopped.
.
