AIR CONDITIONING AND AUDIO 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. 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.
