Hi Droid13,

I actually asked Toyota if one can turn off the Plasmacluster system. I enclose their response below. Were they correct? As I said, no buzzing noise can be heard from the driver's side vent when that vent is closed. Does it mean that the system is off? Or that while it's in operation, it simply cannot be heard? But, if that were the case, were would those ions be discharged when that vent is close?
