■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high. Turning
“A/C” on will dehumidify the air from the outlets and defog the windshield effec-
tively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recirculated air mode is used.
■Outside/recirculated air mode
●When driving on dusty roads such as tunnels or in heavy traffic, set the outside/
recirculated air mode button to the recirculated air mode. This is effective in pre-
venting outside air from entering the vehicle interior. During cooling operation, set-
ting the recirculated air mode will also cool the vehicle interior effectively.
●Outside/recirculated air mode may automatically switch depending on the tem-
perature setting or the inside temperature.
■Automatic mode for air intake control
In automatic mode, the system detects exhaust gas and other pollutants and auto-
matically switches between outside air and recirculated air modes.
When the dehumidification function is off, and the fan is operating, turning automatic
mode on will activate the dehumidification function.
■Pollen removal mode
●In order to prevent the windshield from fogging up when the outside air is cold, the
following may occur:
• Outside air mode does not switch to (recirculated air) mode.
• The dehumidification function operates.
• The operation cancels after approximately 1 minute.
●In rainy weather, the windows may fog up. Press .
●In extremely humid weather, the windows may fog up.
●The pollens are filtered out even if the pollen removal mode is turned off.

■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
interpretation of Regulation (EU) No 528/2012.
Active substances: Charged water particles (nano) containing hydroxyl radicals,
generated 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
maximized. 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.

Maintenance and care
GS350_250_OM_OM30E16E_(EE)
CAUTION
■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
automatically start to run if the air conditioning is on and/or the coolant tempera-
ture is high. (→P. 4 6 1 )
■Safety glasses
Wear safety glasses to prevent flying or falling material, fluid spray, etc. from get-
ting 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 refilling, it may indicate a serious problem.
