- Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature set- ting and ambient conditions. As a result, the following may occur: l Immediately after the “AUTO” button is pressed, the fan may stop for a while until warm or cool air is ready to flow.
l Cool air may flow to the area around the upper body when the heater is on.

- Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used for an extended period.

- Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched to in accordance with the temperature setting and the inside temperature.

- When the outside temperature exceeds 75°F (24°C) and the air conditioning system is on
l In order to reduce the air conditioning power consumption, the air condi- tioning system may switch to recirculated air mode automatically. This may also reduce fuel consumption.
l Recirculated air mode is selected as a default mode when the “ENGINE START STOP” switch is turned to IGNITION ON mode.
l It is possible to switch to outside air mode at any time by pressing .

- Window defogger feature
Recirculated air mode may automatically switch to (outside air) mode in situations where the windows need to be defogged.

• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in “AUTO” mode.

- Air conditioning filter
- Customization
Settings (e.g. exhaust gas sensor sensitivity) can be changed.

CAUTION

- To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather.

The difference between the temperature of the outside air and that of the windshield can cause the outer surface of the windshield to fog up, blocking your vision.

NOTICE

- To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the engine is stopped.
