lated air mode button to the recirculated air mode. This is effective in preventing out-
side air from enteri ng the vehicle interior. During cooling operation, setting the
recirculated air mode will also cool the vehicle interior effectively.

ture setting or the inside temperature.

IGNITION ON mode.
●It is possible to switch to outside air mode at any time by pressing .
