Fogging up of the windows
The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
If you turn off, the windows may fog up more easily.
The windows may fog up if the recirculated air mode is used.
Outside/recirculated air mode
When driving on dusty roads such as tunnels or in heavy traffic, set the out-
side/recirculated air mode dial to the recirculated air mode. This is effective
in preventing outside air from entering the vehicle interior. During cooling
operation, setting the recirculated air mode will also cool the vehicle interior
effectively.
When the indicator light on goes off by itself (vehicles with a
cooling and dehumidification function on/off button)
Press to turn off the dehumidification function and turn it on again.
There may be a problem in the air conditioning system if the indicator light
goes off again. Turn the air conditioning system off and have it inspected by
any authorized Toyota dealer or repairer, or another duly qualified and
equipped professional.
When the outside temperature falls to nearly 0°C (32°F) (vehicles with a
cooling and dehumidification function on/off button)
The dehumidification function may not operate even when is
pressed.

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.
An odor comes from the air conditioning system due to the Stop &
Start system operation (vehicles with a Stop & Start system)
When the engine is stopped due to the Stop & Start system, an odor caused
by moisture may be detected. This does not indicate a malfunction.
Air conditioning filter
P. 502
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 wind-
shield 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.
