■

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.
