AIR CONDITIONING 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. 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 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 until the "AUTO" indicator light flashes. The display changes as illustrated below. The sensitivity of the sensor can be adjusted only while the vehicle has stopped. 272
