AIR CONDITIONING AND AUDIO If manual switching of air intake is desired - If manual on-off of the air conditioning is desired - Push the "A/C" button to turn the air conditioning on and push it again to turn the air conditioning off. 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. The air intake control button is used to switch the air intake between the OUTSIDE AIR mode and RECIRCULATED AIR mode. With the button in the OUTSIDE AIR mode, the OUTSIDE AIR mode indicator light will come on and the system will take fresh outside air into the vehicle. If quick circulation of cooled air is desired, push the air intake control button for RECIRCULATED AIR. The RECIRCULATED AIR mode indicator light will come on. 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. 95
