OPERATION

Description

INFOID:0000000010121767

• This A/C uses various sensors to detect temperature changes in the interior caused by factors such as

changes in ambient temperature and sunload. When the desired temperature is set, the discharge air tem-

perature, discharge air flow, and inlet/outlet changes are controlled automatically to maintain a constant inte-

rior temperature at all times.

• The air flow volume and switching of air inlets and air outlets can be selected manually without auto function.

While using auto function, it is still possible to select a particular item manually.

• It is possible to use A/C-Heater Timer (Climate Ctrl. Timer) or remote climate control to adjust the interior to

a comfortable temperature before entering the vehicle.

TABLE OF OPERATION CONDITIONS OF A/C SYSTEM FUNCTION OPERATED BY POWER
SWITCH OPERATION

Each of the A/C system functions is operative under the following conditions.

×:Operate —: Does not operate

• *1: The vehicles state of each power supply position is following state.

- LOCK/OFF: Power switch OFF

- ACC: Power switch ACC

- ON: Power switch ON (Not vehicle condition READY)

- READY: Shifting to vehicle condition READY (Transmitting the READY signal from BCM to VCM), or Vehicle

condition READY or running

• *2: When the power supply position is ON, cooling/heating function can be started only while charging is in

progress. After charging is complete, cooling/heating function operates continuously while maintaining the

status that EVSE is connected (the status that power supply from EVSE is allowed).

NOTE:

• Connecting EVSE when the vehicle is in READY state cancels READY state (ready indicator lamp turns

OFF), and power supply position changes to ON. At this time, cooling/heating function of A/C system stops,

and only ventilation function operates. When using cooling/heating function, turn power switch OFF, check

that charging is started, and then turn power switch ON again.

• When the power supply position is ON, if power supply from EVSE becomes not available due to the power

interruption, cooling/heating function operates as shown in the following items.

- Charging is in progress:

EV system maintained the activated status for 5 minutes after power supply from EVSE becomes not avail-

able. Therefore, cooling/heating function stops when power supply from EVSE becomes not available. Cool-

ing/heating function re-starts simultaneously when power supply from EVSE becomes available again within

5 minutes. After 5 minutes are passed, EV system stops. Cooling/heating function does not re-start.

- After charging is complete:

EV system stops. Cooling/heating function stops.
