intake mode may change automatically to the OUTSIDE AIR
mode. This is not a malfunction.

come on.

AIR CONDITIONING

removing frost or exterior fog on the windshield, turn the air
conditioning off once it is no longer required. This will improve
fuel economy. The air conditioning can be used for year-round
automatic temperature control including cooling and
dehumidifying operation.
If the air conditioning compressor does not operate, the
indicator of the A/Cº button will blink. If the indicator of the
A/Cº button blinks even when the A/Cº button is pushed
