AIR CONDITIONING (c) Air intake selector 1 RECIRCULATED - Recirculates the air inside the vehicle. 2 FRESH - Draws outside air into the system. Each time you push the air intake control button. The mode changes in order from the RECIRCULATED mode to the FRESH mode, then back to the RECIRCULATED mode. Each indicator light shows which mode is now selected. If quick circulation of cooled air is desired, push the air intake selector button for the RECIRCULATED mode. For normal use, it is best to keep the air intake selector button set to the FRESH mode. If recirculated air is used during heating, the windows will fog up more easily. To prevent fogging up of the windshield, the air intake mode may change automatically to the FRESH 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 FRESH mode. This is not a malfunction. When the engine coolant temperature or electric compressor inverter temperature becomes extremely high, the RECIRCULATED mode is automatically selected. In this case, it is not possible to select to the FRESH mode if you push the air intake control button. This is not a malfunction. When the engine coolant temperature or inverter temperature becomes low, the air intake mode returns to the mode previously used. (d) On-off of the air conditioning Touch the "A/C" switch. To turn the air conditioning on and touch 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 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 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. 157
