AIR CONDITIONING If manual switching of air intake is desired - RECIRCULATED AIR mode - If quick circulation of cooled air is desired, select this mode. 2 OUTSIDE AIR mode - The system will take fresh outside air into the vehicle. 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. In the following cases, the RECIRCULATED mode may change to the OUTSIDE AIR mode automatically to prevent interior fog. D When the outside temperature becomes lower than 5_C (41_F). 1 If manual on-off of the air conditioning is desired - Touch "A/C" to turn the air conditioning on and touch it again to turn the air conditioning off. If the outside temperature is lowered down to around 0_C (32_F), the air conditioning will turn off automatically. 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. Each time you push the air intake control button, the mode changes in order from the RECIRCULATED AIR mode to OUTSIDE AIR mode, then back to the RECIRCULATED AIR mode. Each indicator light shows which mode is now selected. D When the air conditioning compressor malfunctions. D When the air conditioning cooler refrigerant decreases. 181
