■Using automatic mode
Fan speed is adjusted automatically according to the temperature setting
and ambient conditions. As a result, the following may occur:
● The system may switch automatically to recirculated air mode when the
coolest temperature setting is selected when the ambient temperature is
high.
● Immediately after the switch is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
● Cool air may flow to the area around the upper body when the heater is
on.
■ 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, the outside temperature, etc.
■ Using the system in recirculated air mode
The windows will fog up more easily if recirculated air mode is used.
■ Window defogger feature
Recirculated air mode may automatically switch to outside air mode in situa-
tions where the windows need to be defogged.
■ When
is selected for the air outlets used
For your driving comfort, air flowing to the feet may be warmer than air flow-
ing to the upper body depending on the temperature setting.
■ When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehi-
cle after closing the windows, it is recommended that the air intake mode be
set to outside air mode and the fan speed to any setting except off.

■When outside air temperature is below 32°F (0°C)
The cooling and dehumidification function may not operate even when
is pressed.
■ When the indicator light on flashes
Press
to turn off the cooling and dehumidification function and turn it
on again. There may be a problem in the air conditioning system if the indi-
cator light continues to flash. Turn the air conditioning system off and have it
inspected by your Toyota dealer.
■ 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.
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.
