AIR CONDITIONING 1 RECIRCULATED AIR mode - If quick circulation of cooled air is desired, select this mode. 2 EXHAUST GAS AUTOMATIC mode - If the outside air contains harmful substances like exhaust gas (i.e., when the vehicle running just in front of your vehicle accelerates rapidly), the system changes automatically from the OUTSIDE AIR mode (with indicators 2 and 3 on) to the RECIRCULATED mode (with indicators 1 and 2 on). 3 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. Turning off the air conditioning manually will cancel the EXHAUST GAS AUTOMATIC mode. If you select the "AUTO" mode during fan operating, the air conditioning turns on and the EXHAUST GAS AUTOMATIC mode will operate. 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 4_C (39_F). D When the air conditioning compressor malfunctions. D When the air conditioning cooler refrigerant decreases. To change the sensitivity of the sensor switching between the RECIRCULATED and OUTSIDE AIR in the AUTOMATIC mode, push the air intake control button for a few seconds. The display changes as illustrated below. The sensitivity of the sensor can be adjusted only while the vehicle has been stopped. Touch the desired switch. When you push any button except the air intake control button, the above screen disappears. V 137
