3-1. Using the air conditioning system and defogger
■
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 follow.
●
Cool air may flow to the area around the upper body when the heater is on.
■
Using the system in recirculated air mode
The window 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 situations
where the windows need to be defogged.
■
Outside 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.
When the air conditioning is OFF, and the fan is operating, turning the “AUTO”
mode ON will activate the air conditioning system.
