AIR CONDITIONING If manual switching of air intake is desired - 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. When the air conditioning is ON, if the engine coolant temperature becomes extremely high, the RECIRCULATED AIR mode is automatically selected. This is not a malfunction. When the engine coolant temperature is lowered, the previous mode resumes. If manual on-off of the air conditioning is desired - The air intake control button is used to switch the air intake between the OUTSIDE AIR mode and RECIRCULATED AIR mode. With the button in the OUTSIDE AIR mode, the indicator light will turn off and the system will take fresh outside air into the vehicle. 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. 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. 283
