■nanoe (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. These parti-
cles 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 window side air outlet of the driver's seat*.
●When the fan is turned on and “nanoe” on the option control screen is selected, the nanoe is activated.
●When the fan is operated in the following conditions, system performance will be maxi- mized. If the following conditions are not met, the nanoe may not operate at full capacity.
• The upper body, the upper body and feet or the feet air outlets are being used. ( P. 538) • The window side air outlet of the driver’s seat 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.
*: According to temperature and humidity conditions, fan speed and direction of the air
flow, the nanoe may not operate at full capacity.

WARNING
The engine compartment contains many mechanisms and fluids that may move suddenly, become hot, or become electrically energize d. To avoid death or serious injury, observe the following precautions.
■When working on the engine compartment
●Keep hands, clothing and tools away from the moving fan and engine drive belt.
●Be careful not to touch the engine, radiator, exhaust manifold, etc., right after driving
as they may be hot. Oil and other fluids may also be hot.
●Do not leave anything that may burn easily, such as paper and rags, in the engine compartment.
●Do not smoke, cause sparks or expose an open flame to fuel or the battery. Fuel andbattery fumes are flammable.
●Be extremely cautious when working on the battery. It contains poisonous and corro-
sive sulfuric acid.
●Take care because brake fluid can harm your hands or eyes and damage painted sur- faces. If fluid gets on your hands or in your eyes, flush the affected area with clean
water immediately. If you still experience discomfort, consult a doctor.
■When working near the electric cooling fans or radiator grille
Be sure the engine switch is off.
With the engine switch in IGNITION ON mode, the electric cooling fans may auto- matically start to run if the air conditioning is on and/or the coolant temperature is high. ( P. 607)
■Safety glasses
Wear safety glasses to prevent flying or fa lling 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.
