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 th e fan is operating, turning the “AUTO”
mode ON will activate the air conditioning system.

Maintenance and care
■Cleaning the inside of the rear window
Do not use glass cleaner to clean the rear window, as this may cause damage to the
rear window defogger heater wires. Use a cloth dampened with lukewarm water to
gently wipe the window clean. Wipe the window in strokes running parallel to the
heater wires.
■Caring for leather areas
Lexus recommends cleaning the interior of the vehicle at least twice a year to main-
tain the quality of the vehicle’s interior.
■Shampooing the carpets
There are several commercial foaming-type cleaners available. Use a sponge or
brush to apply the foam. Rub in overlappin g circles. Do not apply water. The excel-
lent results are obtained by keep ing the carpet as dry as possible.
■Seat belts
Clean with mild soap and lukewarm water using a cloth or sponge. Also check the
belts periodically for excessive wear, fraying or cuts.
CAUTION
■Water in the vehicle
●Be careful not to splash or spill liquid on the floor.
●Do not get any of the SRS components or wiring in the vehicle interior wet.
