The windshield wiper and washer can be operated when
The power switch is in ON mode.
Dripping prevention wiper sweep
After performing a washing and wiping operation several times, the wipers oper-
ate one more time after a short delay to prevent dripping.
However, the last sweep will not happen if the vehicle is traveling above 170 km/
h (106 mph).
Effects of vehicle speed on wiper operation (vehicles with rain-sensing wind-
shield wipers)
Vehicle speed affects the following even when the wipers are not in AUTO
mode.
Intermittent wiper interval
Wiper operation when the washer is being used (delay until drip prevention
wiper sweep occurs)
With low speed windshield wiper operation selected, wiper operation will be
switched from low speed to intermittent wiper operation only when the vehicle is
stationary.
Raindrop sensor (vehicles with rain-sensing windshield wipers)
If the wiper is turned to AUTO mode 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 85°C (185°F) or higher, or -30°C (-
22°F) or lower, automatic operation may not occur. In this case, operate the
wipers in any mode other than AUTO mode.
When the windshield wipers are in temporary operation (vehicles with rain-sens-
ing windshield wipers)
AUTO mode cannot be activated even if is pressed.
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.
Operation guide display (vehicles with rain-sensing windshield wipers only)
When the windshield wiper switch is operated to activate AUTO mode or when
the rain-sensing level is adjusted, the current status is displayed on the meters for
a few seconds. (P. 1 1 9 )
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 intermittently
strikes the windshield, or if bugs etc. are
present on the windshield.

CAUTION
Caution regarding the use of windshield wipers in AUTO mode
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
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 fluid until the windshield becomes
warm. The fluid may freeze on the windshield and cause low visibility. This
may lead to an accident, resulting in death or serious injury.
NOTICE
When the windshield is dry
Do not use the wipers, as they may damage the windshield.
When there is no washer fluid spray from the nozzle
Damage to the washer fluid pump may be caused if the lever is pulled toward
you and held continually.
When a nozzle becomes blocked
In this case, contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

The shift lever is in D or range 4 or higher of S has been selected.
Range 4 or higher of D has been selected by using the paddle shift.
Vehicle speed is above approximately 50 km/h (30 mph).
Accelerating after setting the vehicle speed
The vehicle can accelerate normally. After acceleration, the set speed resumes.
However, during vehicle-to-vehicle distance control mode, the vehicle speed
may decrease below the set speed in order to maintain the distance to the vehicle
ahead.
Automatic cancelation of vehicle-to-vehicle distance control
Vehicle-to-vehicle distance control driving is automatically canceled in the fol-
lowing situations:
Actual vehicle speed falls below approximately 40 km/h (25 mph).
VSC is activated.
TRC is activated for a period of time.
When the VSC or TRC system is turned off by pressing the VSC OFF switch.
The sensor cannot operate correctly because it is covered in some way.
The windshield wipers are operating at high speed (when the wipers are in
AUTO mode or the high speed wiper operation).
When snow mode is set.
Pre-crash braking is activated.
If vehicle-to-vehicle distance control driving is automatically canceled for any
other reason, there may be a malfunction in the system. Contact any authorized
Lexus dealer or repairer, or another duly qualified and equipped professional.
Automatic cancelation of constant speed control
The cruise control will stop maintaining the vehicle speed in the following situa-
tions:
Actual vehicle speed is more than approximately 16 km/h (10 mph) below the
set vehicle speed.
At this time, the memorized set speed is not retained.

4287-1. Maintenance and care
IS300h_EE(OM53B95E)
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
Exhaust gases cause the exhaust pipes to become quite hot.
When washing the vehicle, be careful not to touch the pipes until they have
cooled sufficiently, as touching hot exhaust pipes 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 mal-
function. If this occurs, consult any authorized Lexus dealer or repairer, or
another duly qualified and equipped professional.
Set the wipers to the intermittent wind-
shield wipers. (P. 238)
If AUTO mode is selected, the wipers may
operate unexpectedly in the following situ-
ations, and may result in hands being
caught or other serious injuries and cause
damage to the wiper blades.
