The automatic air conditioning automatically maintainsthe set temperature.
This air conditioning features automatic fan speed and air flowcontrol which automatically selects the most suitable fanspeed and air flow to control the temperature. The ignition keymust be in the “ON” position.
NOTICE
To prevent the battery from being discharged, do notleave the air conditioning on longer than necessarywhen the engine is not running.

1. Push the “AUTO” button.
An indicator light will illuminate to show that the automaticoperation mode has been selected.
Air flow quantity, switching of the diffusers, on–off of the airconditioning and switching of the air intake betweenRECIRCULATED AIR and OUTSIDE AIR are automaticallyadjusted. The operation status is shown by each indicator.
When one of the manual control buttons is depressed whileoperating in automatic mode, the mode relevant to thedepressed button is set. Other conditions continue to beadjusted automatically.
Push the “OFF” button to turn the air conditioning system off.

2. Turn the “TEMP” knob until the desired temperature isdisplayed.
The “TEMP” knob is used to set the desired passengercompartment temperature. The temperature of air deliveredto the passenger compartment will be controlled automaticallyaccording to the setting. The figures on the panel indicatedegrees Fahrenheit or Centigrade.
When you adjust the temperature selector knob to maximumcooling, a “MAX. COLD” message will appear on the displayand the air intake mode will be automatically changed toRECIRCULATE AIR mode.

SETTING OPERATION – manual control
When one of the manual control buttons is depressedwhile operating in automatic mode, the mode relevant tothe depressed button is set. Other conditions continue tobe adjusted automatically.
If manual air flow selection is desired –
20R005b
The outlets from which air is delivered can be selectedmanually by pushing the button. The function of each mode isas follows:
1 Panel – Air flows mainly from the instrument panel vents.
2 Bi–level – Air flows from both the floor vents and theinstrument panel vents.
3 Floor – Air flows mainly from the floor vents. Unheatedair is also delivered through the side vents during heating.
4 Floor/Windshield – Air flows mainly from the floor ventsand windshield vents. Unheated air is also deliveredthrough the side vents during heating.
If quick heating or cooling is desired –
Turn the “TEMP” knob until “MAX. HOT” or “MAX. COLD”appears on the display.
When the “MAX. COLD” is selected, the air intake isautomatically set to RECIRCULATED AIR mode.
If manual fan speed control is desired –
20R006c
� 1 Toward low fan speed 2 Toward high fan speed
The fan speed can be set to your desired speed by turning thefan speed control button. The higher the fan speed is, the moreair is delivered. Pushing the “OFF” button turns off the fan.

If manual switching of air intake is desired –
20R007a
The air intake control button is used to switch the air intakebetween the OUTSIDE AIR mode and RECIRCULATED AIRmode. The indicator on the switch shows which mode isselected.
� With the indicator on – For RECIRCULATED AIR mode
� With the indicator off – For OUTSIDE AIR mode
For normal use, it is best to keep the setting to OUTSIDE AIRmode. If recirculated air is used during heating, the windowswill fog up more easily.
If the engine coolant temperature becomes extremely high, theRECIRCULATED AIR mode is automatically selected. This isnot a malfunction. When the engine coolant temperature islowered, the previous mode resumes.
To prevent fogging up of the windshield, the air intake modemay change automatically to OUTSIDE AIR mode dependingon the condition of the air conditioning system.
If manual on–off of the air conditioning is desired –
Push the “A/C” button to turn the air conditioning on and pushit again to turn the air conditioning off.
The air conditioning does not work if the outside temperatureis lowered down to around 0�C (32�F).
If the system is used for ventilation, heating in dry weather orremoving frost or exterior fog on the windshield, turn the airconditioning off once it is no longer required. This will improvefuel economy. The air conditioning can be used for year–roundautomatic temperature control including cooling anddehumidifying operation.
If the air conditioning compressor does not operate, theindicator of the “A/C” button will blink. If the indicator of the“A/C” button blinks even when the “A/C” button is pushedagain, have the compressor checked by your nearest Lexusdealer.

(d) Operating tips� Make sure the air inlet grilles in front of the windshield are
not blocked by leaves or other obstructions.
� If air flow control is not satisfactory, check the dashboardvents. (See “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. Afterthe excess heat has blown away, close the windows.
� When driving on dusty roads, close all windows. If dustthrown up by the vehicle is still drawn into the vehicle afterclosing the windows, it is recommended that the air intakecontrol button be left to the OUTSIDE AIR mode and the fanspeed control button be pressed to anywhere except the“OFF” button.
� If following another vehicle on a dusty road, or driving inwindy and dusty conditions, it is recommended that the airintake control button be temporarily pressed in to theRECIRCULATED AIR mode, which will close off the outsidepassage and prevent outside air and dust from entering thevehicle interior.
