244 3-1. Using the air conditioning system and defogger
■Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used for
an extended period.
■ Window defogger feature
In order to prevent the windows from fogging up, recirculated air mode may
automatically switch to outside air mode if the ambient temperature drops.
This feature can be cancelled by pushing and holding the air circulation
mode switch for longer than 2 seconds. The feature will be reactivated when
the engine switch is turned to the “ACC” or “LOCK” position.

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 light continues to flash. Turn the air conditioning system off and have it
inspected by your Toyota dealer.

windshield can cause the outer surface of the windshield to fog up, blocking
your vision.

Do not leave the air conditioning system on longer than necessary when the
engine is off.
