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

It is recommended to switch to
the low beams when use of the
high beams is inappropriate or
when the high beams may
cause problems or distress to
other drivers or pedestrians
nearby.
Pull the lever rearward and then
return it to its original position.
The high beams will illuminate
while the lever is pulled, how-
ever, after the lever is returned

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.

■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-

Constant speed cruising:
When there are no vehicles ahead
The vehicle drives at the speed set by the driver.
If the set vehicle speed is exceeded while driving down a hill, the set vehicle
speed display will blin k and a buzzer will sound.
Deceleration and follow-up cruising
When a preceding vehicle driving slower than the set vehicle
speed is detected
When a vehicle is detected driving ahead of your vehicle, the v ehicle auto-
matically decelerates and if a greater reduction in vehicle spe ed is neces-
sary, the brakes are applied (the stop lights will come on at t his time). The
vehicle is controlled to maintai n the vehicle-to-vehicle distance set by the
driver, in accordance with changes in the speed of the precedin g vehicle. If
vehicle deceleration is not sufficient and the vehicle approaches the vehicle
ahead, the approach wa rning will sound.
Acceleration
When there are no longer any preceding vehicles driving slower
than the set vehicle speed
The vehicle accelerates until th e set vehicle speed is reached and then
resumes constant speed cruising.
Starting off: If a preceding vehi cle stops, the vehicle will also stop
(controlled stop). After the preceding vehicle starts off, pressing
the “RES” switch or depressing the accelerator pedal will resum e
follow-up cruising (start off operation). If a start off operat ion is not
performed, the controlled stop will continue.

Driving
formed within a certain amount
of time, the system will enter
warning phase 2.
After entering warning phase 2,
a buzzer will sound in short
intervals and a message will be
displayed to warn the driver, and
the vehicle will slowly deceler-
ate. If driving operations, such
as holding the steering wheel,
are not performed within a cer-
tain amount of time, the system
will determine that the driver is
not responsive and enter the
deceleration stop phase.
The audio system will be muted
until the driver becomes respon-
sive.
When the vehicle is decelerating,
the brake lights may illuminate,
depending on the road conditions,
etc.
After entering the deceleration
stop phase, a buzzer will sound
continuously and a message will
be displayed to warn the driver,
and the vehicle will slowly decel-
erate and stop. After the vehicle
stops, the system will enter the
stop and hold phase.
After the vehicle is stopped, the
parking brake will be applied automatically. After entering the
stop and hold phase, the buzzer
will continue sounding continu-
ously and the emergency flash-
ers (hazard lights) will flash to
warn other drivers of the emer-
gency.
