Raindrop sensor (vehicles with rain-sensing windshield wipers)
If the wiper switch is turned to the “AUTO” position while the
“POWER” switch is in ON mode, the wipers will operate once to show
that AUTO mode is activated.
If the temperature of the raindrop sensor is 90 C (194 F) or higher, or -
15 C (5 F) or lower, automatic operation may not occur. In this case,
operate the wipers in any mode other than “AUTO”.
If no windshield washer fluid sprays
Check that the washer nozzles are not blocked if there is washer fluid in the
washer fluid tank.
CAUTION
Caution regarding the use of windshield wipers in “AUTO” mode (vehicles
with rain-sensing windshield wipers)
The windshield wipers may operate unexpectedly if the sensor is touched or
the windshield is subject to vibration in “AUTO” mode. Take care that your
fingers etc. do not become caught in the windshield wipers.
The raindrop sensor judges the amount
of raindrops.
An optical sensor is adopted. It may not
operate properly when sunlight from
the rising or setting of the sun intermit-
tently strikes the windshield, or if bugs
etc. are present on the windshield.

CAUTION
Conditions under which the vehicle-to-vehicle distance control may not
function correctly
Apply the brakes as necessary in the following conditions as the radar sen-
sor may not be able to correctly detect vehicles ahead, and a fatal or serious
accident may result:
When water or snow thrown up by the surrounding vehicles hinders the
functioning of the sensor
When your vehicle is pointing upwards (caused by a heavy load in the
luggage compartment etc.)
When the road curves or when the lanes are narrow
When steering wheel operation or your position in the lane is unstable
When the vehicle ahead of you decelerates suddenly
Handling the radar sensor
Observe the following to ensure the cruise control system can function
effectively.
Otherwise, the system may not function correctly and could result in an
accident.
Keep the sensor and grille cover clean at all times.
Clean the sensor and grille cover with a soft cloth so you do not mark or
damage them.
Do not subject the sensor or surrounding area to a strong impact.
If the sensor moves even slightly off position, the system may malfunc-
tion. If the sensor or surrounding area is subject to a strong impact, always
have the area inspected and adjusted by a any authorized Lexus dealer or
repairer, or another duly qualified and equipped professional.
Do not disassemble the sensor.
Do not attach accessories or stickers to the sensor, grille cover or sur-
rounding area.
Do not modify or paint the sensor and grille cover.
Do not replace them with non-genuine parts.

Lexus parking assist-sensor

: If equipped
The distance from your vehicle to nearby obstacles when parallel
parking or maneuvering into a garage is measured by the sensors and
communicated via the multi-information display, touch screen and a
buzzer. Always check the surrounding area when using this system.
Types of sensors
Front corner sensors
Rear corner sensors
Rear center sensors
Lexus parking assist-sensor switch
Turns the Lexus parking
assist-sensor on/off

Sensor detection information
Certain vehicle conditions and the surrounding environment may affect
the ability of a sensor to correctly detect an obstacle. Particular instances
where this may occur are listed below.
• There is dirt, snow or ice on a sensor.
• A sensor is frozen.
• A sensor is covered in any way.
• The vehicle is leaning considerably to one side.
• On an extremely bumpy road, on an incline, on gravel, or on grass
• The vicinity of the vehicle is noisy due to vehicle horns, motorcycle
engines, air brakes of large vehicles, or other loud noises producing
ultrasonic waves.
• There is another vehicle equipped with parking assist sensors in the
vicinity.
• A sensor is coated with a sheet of spray or heavy rain.
• The vehicle is equipped with a fender pole or radio antenna.
• Towing eyelets are installed.
• A bumper or sensor receives a strong impact.
• The vehicle is approaching a tall or right-angled curb.
• In harsh sunlight or intense cold weather
• A non-genuine Lexus suspension (lowered suspension etc.) is
installed.
In addition to the examples above, there are instances in which, because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.
The shape of the obstacle may prevent a sensor from detecting it. Pay
particular attention to the following obstacles:
• Wires, fences, ropes, etc.
• Cotton, snow and other materials that absorb sound waves
• Sharply-angled objects
•Low obstacles
• Tall obstacles with upper sections projecting outwards in the direction
of your vehicle
