water particles through the front center vent on driver’s side
*2.
When the fan is turned on, the “nanoe” system is automatically activated.
When the fan is operated in the following conditions, system performance
will be maximized. If the following conditions are not met, performance
will be limited.

When “nanoe” is generated, a small amount of ozone is emitted and may
be faintly smelled in some situations. However, this is approximately the
same as the amount that already exists in nature, such as in forests, and it
has no affect on the human body.
A slight noise may be heard during operation. This is not a malfunction.
