4-3. Operating the lights and wipers
Driving
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.
WARNING
■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 this case, contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
Do not try to clear it with a pin or other object. The nozzle will be damaged.

WARNING
■Toyota Safety Sense
The Toyota Safety Sense is designed
to operate under the assumption that the driver will drive safely, and is designed to help reduce the impact to
the occupants and the vehicle in the case of a collision or assist the driver in normal driving conditions.
As there is a limit to the degree of rec- ognition accuracy and control perfor-mance that this system can provide,
do not overly rely on this system. The driver is always responsible for paying attention to the vehicle’s surroundings
and driving safely.

■If a warning message is displayed on the multi-information display
A system may be temporarily unavailable or there may be a malfu nction in the sys-
tem.
●In the following situations, perform the actions specified in t he table. When the nor-
mal operating conditions are detected, the message will disappe ar and the system will become operational.
If the message does not disappear, contact any authorized Toyot a retailer or Toyota authorized repairer, or any reliable repairer.
●In the following situations, if the situation has changed (or t he vehicle has been
driven for some time) and the normal operating conditions are d etected, the mes- sage will disappear and the system will become operational.
SituationActions
When the area around a camera is cov-
ered with dirt, moisture (fogged up, cov-
ered with condensation, ice, etc.), or
other foreign matter
Using the wiper and A/C function,
remove the dirt and other attached mat-
ter. ( P.313, 318).
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 conditioning 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.
When “Pre-Collision System Radar In
Self Calibration Unavailable See
Owner’s Manual” is displayed.
Check whether there is attached materi-
als on the radar sensor and radar sensor
cover, and if there is, remove it.

*: If equipped
The system can detect the following (The detectable objects differs
depending on the function.):
The countries and areas for each region listed in the table are current as of
September 2021. However, depending on when the vehicle was sold , the
countries and areas of each region may be different. Contact an y autho-
rized Toyota retailer or Toyota authorized repairer, or any rel iable repairer

PCS (Pre-Collision System)*
The pre-collision system uses a rad ar sensor and front camera to
detect objects ( P.217) in front of the vehicle. When the system
determines that the possibility of a frontal collision with an object is
high, a warning operates to urge the driver to take evasive act ion
and the potential brake pressure is increased to help the drive r
avoid the collision. If the syste m determines that the possibility of a
frontal collision with an object is extremely high, the brakes are
automatically applied to help avoid the collision or help reduc e the
impact of the collision.
The pre-collision system can be disabled/enabled and the warnin g timing
can be changed. ( P.221)
