AIR CONDITIONING If quick circulation of cooled air is desired, push the air intake control button for RECIRCULATED AIR. The indicator light will come on. For normal use, it is best to keep the air intake control button set to the OUTSIDE AIR mode. If recirculated air is used during heating, the windows will fog up more easily. If manual on-off of the air conditioning is desired - Push the "A/C" button to turn the air conditioning on and push it again to turn the air conditioning off. The air conditioning does not work if the outside temperature is lowered down to around 0_C (32_F). If the system is used for ventilation, heating in dry weather or removing frost or exterior fog on the windshield, turn the air conditioning off once it is no longer required. This will improve fuel economy. The air conditioning can be used for year-round automatic temperature control including cooling and dehumidifying operation. If the air conditioning compressor does not operate, the indicator of the "A/C" button will blink. If the indicator of the "A/C" button blinks even when the "A/C" button is pushed again, have the compressor checked by your nearest Lexus dealer. To remove interior fog on the windshield - Push the windshield air flow button. To remove frost or exterior fog on the windshield - 1. Push the "TEMP" button to set the maximum temperature. 2. Push the windshield air flow button. 3. Push the fan speed control button on the right side to obtain a maximum air flow. 4. Leave the "A/C" button off. When the windshield air flow button is pushed, air flows mainly from the windshield vents and turns on the defogging function with the purpose of clearing the front view. Pushing this button once again returns the air flow mode to the last one used. (b) Windshield defogging and defrosting 250
