ES300h_OM_OM33B71U_(U)4-3. Operating the lights and wipers
■Raindrop sensor (vehicles with rain-sensing windshield wipers)
●If the wiper switch is turned to AUTO position while the power switch is in ON mode,
the wipers will operate once to sh
ow that AUTO mode is activated.
●When the sensor sensitivity ring is turned toward high while in AUTO mode, the wipers
will operate once to indicate that the sensor sensitivity is enhanced.
●If the temperature of the raindrop sensor is 185°F (85°C) or higher, or -22°F
(-30°C) or lower, automatic operation ma y not occur. In this case, operate the
wipers in any mode other than AUTO mode.
■If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the windshield
washer fluid reservoir.
●The raindrop sensor judges the amount of
raindrops.
An optical sensor is ad opted. It may not oper-
ate properly when sunlight from the rising or
setting of the sun intermittently strikes the
windshield, or if bugs etc. are present on the
windshield.

■Caution regarding the use of windshield wi pers in AUTO mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or the wind-
shield is subject to vibration in AUTO mode. Take care that your fingers or anything
else do not become caught in the windshield wipers.
■Caution regarding the use of washer fluid
When it is cold, do not use the washer fl uid until the windshield becomes warm. The
fluid may freeze on the windshield and cause lo w visibility. This may lead to an accident,
resulting in death or serious injury.

held continually.
■When a nozzle becomes blocked
In this case, contact your Lexus dealer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.
■When standing the windshield wipers up

●If the part of the windshield in front of th
e camera sensor is fogged up or covered with
condensation or ice, use the windshield defogger to remove the fog, condensation or
ice. ( P. 388)
●Do not apply glass coating agents to the area of the windshield in front of the camera
sensor.
Glass coating agents can be applied to the windshield in areas other than in front of
the camera sensor. However, it will still be necessary to use the wipers if the area of
the windshield in front of the camera sensor is covered with water droplets.
●If water droplets cannot be properly remove d from the area of the windshield in front
of the camera sensor by the windshield wi pers, replace the wiper rubber or wiper
blade.
If the wiper inserts or wiper blades need to be replaced, contact your Lexus dealer.
●Do not attach window tinting to the windshield.
●Replace the windshield if it is damaged or cracked.
If the windshield needs to be re placed, contact your Lexus dealer.
●Do not get the camera sensor wet.
●Do not allow bright lights to shine into the camera sensor.
●Do not dirty or damage the camera sensor.
When cleaning the inside of the windshield , do not allow glass cleaner to contact the
lens. Also, do not touch the lens.
If the lens is dirty or damag ed, contact your Lexus dealer.
●Do not subject the camera sensor to a strong impact.
●Do not change the installation position or di rection of the camera sensor or remove it.
●Do not disassemble the camera sensor.
●Do not install an electronic device or device that emits strong electric waves near the
camera sensor.
●Do not modify any components of the vehicle around the camera sensor (inside rear
view mirror, sun visors, etc.) or ceiling.
●Do not attach any accessories that may obst ruct the camera sensor to the hood, front
grille or front bumper. Contact your Lexus dealer for details.
●If a surfboard or other long object is to be mounted on the roof, make sure that it will
not obstruct the camera sensor.

■Operational conditions
For vehicles sold in regions where the pedestrian detection function and pre-collision
braking function are available*4

●Pre-collision warning:
• Vehicle speed is approximately 7 mph (1 0 km/h) or more. (For detecting a pedes-
trian, vehicle speed is between approxim ately 7 and 50 mph (10 and 80 km/h).)
• The relative speed between your vehicl e and the vehicle or pedestrian ahead is
approximately 7 mph (10 km/h) or more.
●Pre-collision brake assist:
• Vehicle speed is approximately 19 mph (3 0 km/h) or more. (For detecting a pedes-
trian, vehicle speed is between approxim ately 19 and 50 mph (30 and 80 km/h).)
• The relative speed between your vehicl e and the vehicle or pedestrian ahead is
approximately 19 mph (30 km/h) or more.
●Pre-collision braking:

■If the PCS warning light flashes and a warnin
g message is displayed on the multi-infor-
mation display
The pre-collision system may be temporarily unavailable or there may be a malfunction
in the system.
●In the following situations, the warning light will turn off, the message will disappear and
the system will become operational when normal operating conditions return:
• When the radar sensor or camera sensor or the area around either sensor is hot, such as in the sun
• When the radar sensor or camera sensor or the area around either sensor is cold,
such as in an extremely cold environment
• When the radar sensor or front grille embl em is dirty or covered with snow, etc.
• If the camera sensor is obst ructed, such as when the hood is open or a sticker is
attached to the windshield near the camera sensor
●If the PCS warning light continues to flash or the warning message does not disappear,
the system may be malfunctioning. Have the vehicle inspected by your Lexus dealer
immediately.
■If VSC is disabled
●If VSC is disabled ( P. 274), the pre-collision brake assist and pre-collision braking
functions are also disabled.
●The PCS warning light will turn on and “V SC Turned Off Pre-collision Brake System
