AIR CONDITIONING If manual switching of air intake is desired - 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 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). The air intake control button is used to switch the air intake between the OUTSIDE AIR mode and RECIRCULATED AIR mode. To turn the air source to the RECIRCULATED AIR mode, press the button. The indicator will come on. To turn the air source to OUTSIDE AIR mode, press the button again. The indicator will go off. To prevent fogging up of the windshield, the air intake mode may change automatically to the OUTSIDE AIR mode depending on the condition of the air conditioning system. For example, when the ambient temperature is low, the air intake mode may change automatically to the OUTSIDE AIR mode. This is not a malfunction. 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. Displaying the outside temperature - The temperature display ranges from −30_C (−22_F) up to 50_C (122_F). 182
