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 outside rear
view mirror (the blind spot), and advises the driver of the vehicle’s existence via
the outside rear view mirror indicator.
The areas that vehicles can be detected in are outlined below.
The range of the detection area
extends to:
Approximately 3.5 m (11.5 ft.) from
the side of the vehicle
The first 0.5 m (1.6 ft.) from the side of
the vehicle is not in the detection area
Approximately 3 m (9.8 ft.) from the

■Cautions regarding the use of the system
The driver is solely responsible for safe driving. Always drive safely, taking care to
observe your surroundings.
The Blind Spot Monitor function is a supplementary function which alerts the driver
that a vehicle is present in the blind spot. Do not overly rely on the Blind Spot Monitor
function. The function cannot judge if it is safe to change lanes, therefore over reliance
could cause an accident resulting in death or serious injury.
According to conditions, the system may not function correctly. Therefore the driver’s
own visual confirmation of safety is necessary.

■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 produc t 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 an d “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 op eration. This is not a malfunction.

*2: According to temperature and humidity conditions, fan speed and direction of the
air flow, the nanoe  system may not operate at full capacity.

■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 bo dy 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 malfunction. If
this occurs, consult any authorized Lexus dealer or repairer, or another duly qualified
and equipped professional.
