accordance with the temperature setting and the inside temperature.

●
"ENGINE START STOP" switch is turned to IGNITION ON mode.

where the windows need to be defogged.

The cooling and dehumidification function may not operate even when

Air conditioning odors
■
During use, various odors from inside and outside the vehicle may enter into
●
and accumulate in the air conditioning system. This may then cause odor to be
emitted from the vents.
To reduce potential odors from occurring:
●
• It is recommended that the air conditioning system be set to outside air mode
prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.
