roundings. This may cause the
low beams to remain on or the
high beams to flash or dazzle
pedestrians or vehicles ahead. In
such a case, it is necessary to
manually change between the
high beams and low beams.
• When there are lights similar to
headlights or tail li ghts in the sur-
rounding area
• When headlights or tail lights of
vehicles ahead are turned off,
dirty, changing color, or not aimed
properly
• When the headlights are repeat- edly changing between the high
beams and low beams.
• When use of the high beams is inappropriate or when the high
beams may be flashing or daz-
zling pedestrians or other drivers.
• When the vehicle is used in an area in which vehicles travel on
the opposite side of the road of
the country for wh ich the vehicle
was designed, for example using
a vehicle designed for right-hand
traffic in a left-hand traffic area, or
vice versa

The power swit ch is in ON.
■Effects of vehicle speed on
wiper operation
Vehicles with intermittent wind-
shield wipers
With low speed windshield wiper
operation selected, wiper operation
will be switched fro m low speed to
intermittent wiper operation when
the vehicle is stationary. (However,
when the wiper intervals are
adjusted to highest level, the mode
will not switch.)
Vehicles with rain-sensing wind-
shield wipers
With low speed windshield wiper
operation selected, wiper operation
will be switched fro m low speed to
intermittent wiper operation when
the vehicle is stationary. (However,
when the sensor sensitivity is
adjusted to the highest level, the
mode will not switch.)
■Raindrop sensor (vehicles with
rain-sensing windshield wipers)
●The raindrop sensor judges the
amount of raindrops. An optical
sensor is adopt ed. It may not
operate properly when sunlight
from the rising or setting of the
sun intermittently strikes the wind-
shield, or if bugs, etc., are present
on the windshield.
●If the wiper switch i s turned to the
“AUTO” position while the power
switch is in ON, the wipers will
operate once to show that “AUTO”
mode is activated.
●If the wiper sensitivity is adjusted

2565-3. Operating the lights and wipers
Owners Manual_USA_M42C01_ento higher, the wip
er may operate
once to indicate the change of
sensitivity.
●If the temperature of the raindrop
sensor is 194°F (90°C) or higher,
or 5°F (-15°C) or lower, the auto-
matic operation m ay not occur. In
this case, operate the wipers in
any mode other than “AUTO”.
■If no windshield washer fluid
sprays
Check that the wash er nozzles are
not blocked if there is washer fluid in
the windshield washer fluid reser-
v oi r.
WARNING
■Caution regarding the use of
windshield wipers in “AUTO”
mode (vehicles with rain-
sensing windshield wipers)
The windshield wipers may oper-
ate unexpectedly if the sensor is
touched or the windshield is sub-
ject to vibration in “AUTO” mode.
Take care that your fingers or any-
thing else does 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 washer fluid tank is
empty
Do not operate the switch continu-
ally as the washer fluid pump may
overheat.
■When a nozzle becomes
blocked
In this case, contact your Toyota
dealer.
Do not try to clear it with a pin or
other object. The nozzle will be
damaged.
■To prevent 12-volt battery dis-
charge
Do not leave the wipers on longer
than necessary when the EV sys-
tem is off.

WARNING
■To prevent malfunction of the
radar sensors
Observe the following precau-
tions. Failure to do so may lead to
a radar sensor not operating prop-
erly, possibly leading to an acci-
dent resulting in death or serious
injury.
●Keep the radar sensors and
radar sensor covers clean at all
times.
Clean the front of a radar sensor
or the front or back of a radar sen-
sor cover if it is dirty or covered
with water drople ts, snow, etc.
When cleaning the radar sensor
and radar sensor cover, use a soft
cloth to remove di rt so as to not
damage them.

●Do not attach accessories,
stickers (including transparent
stickers), aluminum tape, etc. to
a radar sensor or radar sensor
cover and their surrounding
area.
●Do not subject a radar sensor or
its surrounding area to impact. If
a radar sensor, the front grille,
or front bumper has been sub-
jected to a impact, have the
vehicle inspected by your Toy-
ota dealer.
●Do not disassemble the radar
sensors.
●Do not modify or paint the radar
sensors or radar sensor cover,
or replace them with anything
other than Toyota genuine parts.
●In the following situations, recal-
ibration of the radar sensors will
be necessary. For details, con-
tact by your Toyota dealer.
• When a radar sensor is removed and installed, or
replaced
• When the front bumper or the front grille has been replaced
■Radar sensor cover with a
heater
When the system determines that
snow may pile up over the radar
sensor cover, the heater will oper-
ate automatically. If the area
around the radar sensor cover is
to be touched, such as during
cleaning, make sure that the radar
sensor cover is cool enough to
prevent burns.
■To prevent malfunction of the
front camera
Observe the following precau-
tions. Failure to do so may lead to
the front camera not operating
properly, possibly leading to an
accident resulting in death or seri-
ous injury.

the vehicle has been changed due
to modifications
●When the windshield is dirty,
fogged up, cracked or damaged

nel
●When the lens of a headlight is
dirty and illumination is weak

aligned
●When a headlight is malfunction-
ing

rounding area changes suddenly
●When driving near a TV tower,
broadcasting station, electric
power plant, radar equipped vehi-
cles, etc., or other location where
strong radio waves or electrical
noise may be present
●When a wiper blade is blocking
the front camera
●When in a location or near objects
which strongly reflect radio waves,
such as the following:
• Tunnels
• Truss bridges
• Gravel roads
• Rutted, snow-covered roads
• Walls
• Large trucks
• Manhole covers
• Guardrail
• Metal plates
●When near a step or protrusion
●When a detectable vehicle is nar-
row, such as a small mobility vehi-
cle
●When a detectable vehicle has a
small front or rear end, such as an
unloaded truck
●When a detectable vehicle has a
low front or rear end, such as a
low bed trailer
●When a detectable vehicle has
extremely high ground clearance
WARNING
●Do not modify or change the
headlights and other lights.
■Front camera installation area
on the windshield
If the system determines that the
windshield may be fogged up, it
will automatically operate the
heater to defog the part of the
windshield around the front cam-
era. When cleaning, etc., be care-
ful not to touch the area around
the front camera until the wind-
shield has cooled sufficiently, as
touching it may cause burns.

PCS (Pre-Collision Sys-
tem)
The pre-collision system
uses sensors to detect
objects ( P.266) in the path
of the vehicle. When the
system determines that the
possibility of a frontal colli-
sion with a detectable
object is high, a warning
operates to urge the driver
to take evasive action and
the potential brake pressure
is increased to help the
driver avoid the collision. If
the system determines that
the possibility of a collision
is extremely high, the
brakes are automatically
applied to help avoid the
collision or help reduce the
impact of the collision.
The pre-collision system can
be disabled/enabled and the
warning timing can be
changed. ( P.275)

the system judges that the steering
wheel has been operated, the warn-
ing buzzer will sound for a certain
amount of time.
■Break suggestion function
If the vehicle is swaying, a message
will be displayed and a warning
buzzer will sound to u rge the driver
to take a break.
Depending on the condition of the
vehicle and road surface, the break
