AIR CONDITIONING If manual on-off of the air conditioning is desired Push the "A/C" switch to turn the air conditioning on and push 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 button 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. (b) Windshield defogging and defrosting When the "FRONT WINDSHIELD" button is pushed while operating in automatic mode, the air conditioning is set to operate and the OUTSIDE AIR mode is set. Push the "A/C" switch for dehumidified heating or cooling. This setting clears the front view more quickly. If you push the "FRONT WINDSHIELD" button once again while in the FRONT WINDSHIELD mode, the mode then returns to the last mode used. CAUTION To remove interior fog on the windshield Push the "FRONT WINDSHIELD" button. To remove frost or exterior fog on the windshield 1. Push the upper side of the temperature control button until maximum figure appears on the temperature display. 2. Push the "FRONT WINDSHIELD" button. 3. Push the "HI" of the air flow control switch to obtain a maximum air flow. 4. Leave the air conditioning on-off button off. For further information for removing frost and fog, see "Lower vent" on page 139. Do not use the "FRONT WINDSHIELD" 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. V 137
