The windows will fog up more easily if recirculated air mode is used.
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.
A sensor, which detects humidity inside
the vehicle and the temperature of the
windshield, is provided to detect fog on
the front windscreen. Due to the sensor,
when automatic mode is set the air condi-
tioning may make the following controls:
Changing the amount of air flow

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 AUTO
mode.
Customization
Settings (e.g. enable/disable automatic operation of the air conditioning
compressor when the “AUTO” switch ON) can be changed.
(Customizable features P. 667)
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.
