n Using the automatic mode

ting and ambient conditions. As a result, the following may occur.

warm or cool air is ready to flow.
l Cool air may flow to the area around the upper body when the heater is
on.

The windows will fog up more easily if the recirculated air mode is used for
an extended period.
n 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.
n Window defogger feature

in situations where the windows need to be defogged.

n When the indicator on flashes
Press and turn off the air conditioning system before turning it on
once more. There may be a problem in the air conditioning system if the indi-
cator continues to flash. Turn the air conditioning system off and have it
inspected by your Toyota dealer.

into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.

• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
