AIR CONDITIONING If manual on−off of the air conditioning is desired- Touch the "A/C" switch to turn the air conditioning on and touch it again to turn the air conditioning off. If you turn off the air conditioning manually, the EXHAUST GAS AUTOMATIC mode will be cancelled. If the outside temperature is lowered down to around 0_C (32_F), the air conditioning will turn off automatically. At this time, the indicator on the A/C switch is off and the EXHAUST GAS AUTOMATIC indicator light remains on. However, the EXHAUST GAS AUTOMATIC mode does not operate. When the air conditioning turns on as with the raised temperature, the EXHAUST GAS AUTOMATIC mode resumes. 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" switch will blink. If the indicator of the "A/C" switch blinks even when the "A/C" switch is touched again, have the compressor checked by your nearest Lexus dealer.
