Automatic Air Conditioning Controls 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 display light of the "A/C" switch will blink. If the display light of the "A/C" switch blinks even when the "A/C" switch is touched again, have the compressor checked by your nearest Lexus dealer. If the engine coolant temperature becomes extremely high, the air conditioning may shut off automatically to resolve emergency situation for engine cooling. This is not a malfunction. When the engine coolant temperature is lowered, the air conditioning comes on automatically. (b) Windshield defogging and defrosting 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. NRY018 This button allows the air intake to select the OUTSIDE AIR mode automatically. This is to clean up the front view more quickly. If you want to return the setting to the RECIRCULATED AIR mode, push the air intake control button once again. Touch the "A/C" switch for dehumidified heating or cooling. This setting clears the front view more quickly. 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. Touch the fan speed control switch on the right side to obtain a maximum air flow. 4. Leave the "A/C" switch off. CAUTION Do not use the windshield air flow button during cooled air operation in extremely humid weather. The difference between the temperature of the outside air and that of the windshield could cause the outer surface of the windshield to fog up blocking your vision. 138
