mode indicator light will come on and the system will take fresh
outside air into the vehicle.
If quick circulation of cooled air is desired, press in the air
intake control button for RECIRCULATED AIR. The
RECIRCULATED AIR mode indicator light will come on.

push it again to turn the air conditioning off.
If the system is used for ventilation, heating in dry weather or
removing the frost or exterior fog on the windshield, press the
air conditioning on − off button once again. This turns off the air
conditioning and improves fuel economy. For year-round
automatic temperature control including cooling and
dehumidifying operation, use the air conditioning.

Be sure the air inlet grilles in front of the windshield are not

If air flow control is not satisfactory, check the dashboard
vents. (See “Center vents”, “Side vents” and “Rear vents”.)

To help cool down the interior after parking in the hot sun,
drive for the first few minutes with the windows open. After
the excess heat has blown away, close the windows.

When driving on dusty roads, close all windows. If dust
thrown up by the vehicle is still drawn into the vehicle after
closing the windows, it is recommended that the air intake
control button be left to the OUTSIDE AIR mode and the fan
speed control button be pressed to anywhere except the
“OFF” button.

If following another vehicle on a dusty road, or driving in
windy and dusty conditions, it is recommended that the air
intake control button be temporarily pressed in to the
RECIRCULATED AIR mode, which will close off the outside
passage and prevent outside air and dust from entering the
vehicle interior.

The air filter may clog after long use and reduce the air flow.
Have it inspected by your Lexus dealer according to the
maintenance schedule.
