■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature setting and
ambient conditions. As a result, the following may occur.
●The system may switch automatically to recirculated mode when the coolest
temperature setting is selected in summer.
●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.
■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
Recirculated air mode may automatically switch to
(outside air) mode in sit-
uations where the windows need to be defogged.
■Outside air temperature approaches 32 °F (0 °C).
The air conditioning system may not operate even when
is pressed.
■When the indicator light 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 indicator light
continues to flash. Turn the air conditioning system off and have it inspected by your
Lexus dealer.
■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and auto-
matically switches between outside air and recirculated air modes.
CAUTION
■To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The dif-
ference between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
