The Blind Spot Monitor function uses radar sensors to detect vehicles that
are traveling in an adjacent lane in the area that is not reflected in the out-
side rear view mirror (the blind spot), and advises the driver of the vehi-
cle’s existence via the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.

other vehicles etc. before backing up. Failure to do so could cause death or serious
injury.
According to conditions, the system ma y not function correctly. Therefore the
driver’s own visual confirmation of safety is necessary.

GS350_250_OM_OM30E16E_(EE)
■Registering air conditioning settings to electronic keys
●Unlocking the vehicle using an electronic key and turning the engine switch to
IGNITION ON mode will recall that key’s registered air conditioning settings.
●When the engine switch is turned off, the current air conditioning settings will auto-
matically be registered to the electronic key that was used to unlock the vehicle.
The system may not operate correctly if more than one electronic key is in the vicinity
or if the smart entry & start system is used to unlock a passenger door.
Settings for the electronic key and the corresponding door can be changed. Contact
any authorized Lexus dealer or repairer, or another duly qualified and equipped pro-
fessional.
■Using automatic mode
●Fan speed is adjusted automatically according to the temperature setting and the
ambient conditions.
Therefore, the fan may stop for a while until warm or cool air is ready to flow imme-
diately after is pressed.
●Cool air may blow around the upper body even when the heater is on due to sun-
light.
■Humidity sensor
A sensor, which detects humidity inside the
vehicle and the temperature of the wind-
shield, is provided to detect fog on the front
windscreen. Due to the sensor, when auto-
matic mode is set the air conditioning may
make the following controls:
●Changing the amount of air flow
●Changing the amount of air introduced from
outside when in outside air mode with the air
vents in the position
●Changing the settings of the air vents to
when the is set

■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.

GS350_250_OM_OM30E16E_(EE)
CAUTION
■To prevent the windshield from fogging up
Do not use
during cool air operation in extremely humid weather. The differ-
ence between the temperature of the outside air and that of the windshield can
cause the outer surface of the windshield to fog up, blocking your vision.
■nanoe  generator
Do not disassemble or repair the generator because it contains high voltage parts.
Contact any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional if the generator needs repair.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
■Humidity sensor
Follow these points to avoid damaging the sensor:
●Do not disassemble the sensor
●Do not spray the glass cleaner on the sensor or subject it to strong impacts
●Do not stick anything on the sensor
■To prevent damage to the nanoe 
Do not insert anything into the driver’s side vent, attach anything to it, or use sprays
around the driver’s side vent. These things may cause the generator not to work
properly.

GS350_250_OM_OM30E16E_(EE)
■Outside rear view mirror rain-clearing coating (if equipped)
Observe the following precautions in order to retain the rain-clearing properties of
the mirrors:
●Clean the mirrors using a car shampoo or glass cleaner that does not contain sili-
cone or an abrasive compound, and rinse thoroughly with water.
●Allow the mirrors to be exposed to direct sunlight for 1 to 2 days.
CAUTION
■When washing the vehicle
Do not apply water to the inside of the engine compartment. Doing so may cause
the electrical components etc. to catch fire.
■When cleaning the windshield (vehicles with rain-sensing windshield wipers)
●When the upper part of the windshield where the raindrop sensor is located is
touched by hand
●When a wet rag or similar is held close to the raindrop sensor
●If something bumps against the windshield
●If you directly touch the raindrop sensor body or if something bumps into the
raindrop sensor
■Precautions regarding the exhaust pipes and rear bumper diffusers
Exhaust gases cause the exhaust pipes and rear bumper diffusers to become quite
hot.
When washing the vehicle, be careful not to touch the pipes and diffusers until they
have cooled sufficiently, as touching hot exhaust pipes and rear bumper diffusers
can cause burns.
■Precaution regarding the rear bumper with Blind Spot Monitor (if equipped)
If the paint of the rear bumper is chipped or scratched, the system may malfunc-
tion. If this occurs, consult any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
Turn off AUTO mode of the wiper to prevent
the wiper from operating. ( →P. 2 7 2 )
If AUTO mode is selected, the wipers may
operate unexpectedly in the following situa-
tions, and may result in hands being caught
or other serious injuries and cause damage
to the wiper blades.

NOTICE
■When cleaning the inside of the windshield (vehicles with LKA [Lane-Keeping
Assist])
Be careful not to touch the camera sensor (→P. 3 0 5 ) .
If the camera is accidentally scratched or hit, LKA may not operate properly or
may cause a malfunction.
■Cleaning the inside of the rear window
●Do not use glass cleaner to clean the rear window, as this may cause damage to
the rear window defogger heater wires or antenna. Use a cloth dampened with
lukewarm water to gently wipe the window clean. Wipe the window in strokes
running parallel to the heater wires or antenna.
●Be careful not to scratch or damage the heater wires or antenna.
