8. PLASMACLUSTER (ION GENERATOR) CONTROL (w/ Plasmacluster (Ion Generator))
(a) General:
(1) A Plasmacluster (ion generator) is provided inside the air duct of the side register on the driver seat side to
improve the air quality and comfort in the cabin.
(2) This generator is controlled by the A/C amplifier and operates in conjunction with the blower motor.
NOTICE:
The Plasmacluster (ion generator) uses a high voltage, which is hazardous. Therefore, if the Plasmacluster (ion
generator) requires repairs, be sure to have them done at a TOYOTA dealer.
Do not apply any type of spray (such as a cleaning solvent or hair spray) or stick any foreign matter into the
Plasmacluster ion outlet, as this could cause improper operation or a malfunction.
After use, dust may accumulate around the side register on the driver seat side. If this occurs, press the OFF
switch on the A/C control assembly to stop the blower motor before cleaning the area.
It is normal for the Plasmacluster (ion generator) to emit a slight sound during operation. This sound is created
when electrons collide with the electrode while Plasmacluster ions are being generated.
