3565-2. Using the air conditioning system and defogger
GS450h_300h_OM_OM30F92E_(EE)
■nanoe *1 system (if equipped)
Your vehicle incorporates a nanoe  device, which is considered a biocidal product. The nanoe  device generates charged water particles from the ambient air and these purify
the air in the cabin by suppressing bacteria.
The nanoe  device is considered a biocidal product in the EU according to the interpre- tation of Regulation (EU) No 528/2012.
Active substances: Charged water particles (nano) containing hydroxyl radicals, gener- ated from ambient air
nanoe  helps to provide purified air by emitting electrically charged water particles
through the front center vent on the driver’s side*2.
●When the fan is turned on and “nanoe” on the option control screen is selected, the nanoe  system is activated.
●When the fan is operated in the following conditions, system performance will be maxi- mized. If the following conditions are not met, performance will be limited.
• The , or air outlets are being used.
• The front center vent on driver’s side is open.
●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.
*1:nanoe  and the nanoe mark are trademarks of Panasonic Corporation.
*2: According to temperature and humidity conditions, fan speed and direction of the
air flow, the nanoe  system may not operate at full capacity.

water immediately. If you still experi ence discomfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the power switch is off.
With the power switch in ON mode, the electric cooling fans may automatically start to run if the air conditioning is on and/or the coolant temperature is high. ( P. 411)
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from getting in your eyes.
NOTICE
■If you remove the air cleaner filter
Driving with the air cleaner filter removed may cause excessive engine wear due to dirt in the air.
■If the fluid level is low or high
It is normal for the brake fluid level to go down slightly as the brake pads wear or when the fluid level in the accumulator is high.
If the reservoir needs frequent refillin g, it may indicate a serious problem.
