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.

WARNING
■To avoid malfunction of the radar sensor
Observe the following precautions.
Otherwise, the radar sensor may not operate properly, possibly leading to an accident resulting in death or seri-
ous injury.

WARNING
●Keep the radar sensor and the radar sensor cover clean at all
times.
Radar sensor
Radar sensor cover
If the front of the radar sensor or the
front or back of the radar sensor
cover is dirty or covered with water
droplets, snow, etc., clean it.
Clean the radar sensor and radar
sensor cover with a soft cloth to avoid
damaging them.
●Do not attach accessories, stickers
(including transparent stickers) or other items to the radar sensor, radar sensor cover or surrounding
area.
●Do not subject the radar sensor or
its surrounding area to a strong impact.If the radar sensor, front grille, or
front bumper has been subjected to a strong impact, have the vehicle inspected by any authorized Toy-
ota retailer or Toyota authorized repairer, or any reliable repairer.
●Do not disassemble the radar sen-sor.
●Do not modify or paint the radar sensor or radar sensor cover.
●In the following cases, the radar sensor must be recalibrated. Con-tact any authorized Toyota retailer
or Toyota authorized repairer, or any reliable repairer for details.
• When the radar sensor or front
grille are removed and installed, or replaced
• When the front bumper is replaced
■To avoid malfunction of the front camera
Observe the following precautions. Otherwise, the front camera may not operate properly, possibly leading to
an accident resulting in death or seri- ous injury.
●Keep the windshield clean at all times.
• If the windshield is dirty or covered with an oily film, water droplets, snow, etc., clean the windshield.
• If a glass coating agent is applied to the windshield, it will still be neces-
sary to use the windshield wipers to remove water droplets, etc., from the area of the windshield in front of
the front camera.
• If the inner side of the windshield
where the front camera is installed is dirty, contact any authorized Toy-ota retailer or Toyota authorized
repairer, or any reliable repairer.

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.221, 225).
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

Check whether there is attached materi-
als on the radar sensor and radar sensor

The system can detect the follow-
ing (The detectable objects differs
depending on the function.):
Vehicles

■Pre-collision warning
When the system determines that
the possibility of a frontal collision is
high, a buzzer will sound and a
warning message will be displayed
on the multi-information display to
urge the driver to take evasive
action.
“BRAKE!”
■Pre-collision brake assist
When the system determines that
the possibility of a frontal collision is
high, the system applies greater
braking force in relation to how
strongly the brake pedal is
depressed.
■Pre-collision braking
If the system determines that the
possibility of a frontal collision is
extremely high, the brakes are
automatically applied to help avoid
the collision or reduce the impact of
the collision.

PCS (Pre-Collision Sys-
tem)
The pre-collision system uses
a radar sensor and front cam-
era to detect objects ( P.161)
in front of the vehicle. When
the system determines that the
possibility of a frontal collision
with an object is high, a warn-
ing operates to urge the driver
to take evasive action and the
potential brake pressure is
increased to he lp the driver
avoid the collision. If the sys-
tem determines that the possi-
bility of a frontal collision with
an object is extremely high, the
brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.
The pre-collision system can be
disabled/enabled and the warn-
ing timing can be changed.
