■Effects of vehicle speed on wiper
operation (vehicles with rain-sens- ing windshield wipers)
Vehicle speed affects the Intermittent
wiper interval.
■Raindrop sensor (vehicles with rain-sensing 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
intermittently strikes the windshield, or
if bugs etc. are present on the wind- shield.
●If the wiper is turned to AUTO mode while the engine switch is in ON, the
wipers will operate once to show that
AUTO mode is activated.
●If the temperature of the raindrop sen-
sor is 85°C (185°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 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.
■When stopping the engine in an
emergency while driving
If the windshield wipers are operating when the engine is stopped, the wind-
shield wipers will operate in high speed
operation. After the vehicle is stopped, operation will return to normal when the
engine switch is turned to ON, or opera-
tion will stop when the driver’s door is opened.
WA R N I N G
■Caution regarding the use of
windshield wipers in AUTO mode
(vehicles with rain-sensing wind- shield wipers)
The windshield wipers may operate
unexpectedly if the sensor is touched or the windshield is subject to vibra-
tion in AUTO mode. Take care that
your fingers or anything else do not
become caught in the windshield wip- ers.
■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, result- ing in death or serious injury.
NOTICE
■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 the following situations, if the situation has changed (or the vehicle has been
driven for some time) and the normal operating conditions are detected, the mes- sage will disappear and the system will become operational.
If the message does not disappear, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
• When the temperature around t he radar sensor is outside of the operational range,
such as when the vehicle is in the sun or in an extremely cold environment
• When the front camera cannot detect objects in front of the vehicle, such as when driving in the dark, snow, or fog, or when bright lights are shining into the front
camera
SituationActions
When the area around a sensor is cov-
ered with dirt, moisture (fogged up, cov-
ered with condensation, ice, etc.), or
other foreign matter
To clean the part of the windshield in
front of the front camera, use the wind-
shield wipers or the windshield defogger
of the air conditioning system ( P.424,
429).
When the temperature around the front
camera is outside of the operational
range, such as when the vehicle is in the
sun or in an extremely cold environment
If the front camera is hot, such as after
the vehicle had been parked in the sun,
use the air conditi oning system to
decrease the temperature around the
front camera.
If a sunshade was used when the vehicle
was parked, depending on its type, the
sunlight reflected from the surface of the
sunshade may cause the temperature of
the front camera to become excessively
high.
If the front camera is cold, such after the
vehicle is parked in an extremely cold
environment, use the air conditioning
system to increase the temperature
around the front camera.
The area in front of the front camera is
obstructed, such as when the hood is
open or a sticker is attached to the part of
the windshield in front of the front cam-
era.
Close the hood, remove the sticker, etc.
to clear the obstruction.
