Fogging up of the windows
●The windows will easily fog up when the humidify in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively. (vehicles with an air conditioning on/off button)
● If you turn off, the windows may fog up more easily. (vehicles with
an air conditioning on/off button)
● 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 button to the recirculated air mode. This is effec-
tive 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 an
air conditioning 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
your Toyota dealer.
■ When the outside temperature falls to nearly 32°F (0°C) (vehicles with
an air conditioning 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.

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 syst em on longer than necessary when the
engine is stopped.
