tion
Pulling the lever operates the wipers
and washer.
The wipers will automatically operate a
couple of times after the washer squirts.
(After operating several times, the wip-
ers operate once more time after a
short delay to prevent dripping. How-
ever, the dripping prevention does not
operate while the vehicle is moving.)
Vehicles with headlight cleaners: When
the power switch is in ON and the
headlights are on, if the lever is pulled,
the headlight cleaners will operate
once. After this, the headlight cleaners
will operate every 5th time the lever is
pulled.
■The windshield wipers and washer can be operated when
The power switch is in ON.
■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 switch is turned to the “AUTO” position while the power
switch is in ON, the wipers will operate once to show that AUTO mode is acti-vated.
●If the temperature of the raindrop sen-
sor is 90°C (194°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 washer fluid tank.

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, etc. do 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, result- ing in death or serious injury.
NOTICE
■When the washer fluid tank is empty
Do not operate the switch continually
as the washer fluid pump may over- heat.
■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.
■To prevent 12-volt battery dis-
charge
Do not leave the wipers on longer than necessary when the EV system
is off.

PCS (Pre-Collision Sys-
tem)
The pre-collision system uses
sensors to detect objects
( P.284) in the path of the
vehicle. When the system
determines that the possibility
of a frontal collision with a
detectable obj ect is high, a
warning operates to urge the
driver to take evasive action
and the potential brake pres-
sure 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 colli-
sion.
The pre-collision system can be
disabled/enabled and the warn-
ing timing can be changed.
( P.293)
WARNING
■For safe use
●Driving safely is solely the responsi-
bility of the driver. Pay careful atten- tion to the surrounding conditions in order to ensure safe driving. Never
use the pre-collision system in place of normal braking operations. This system cannot help avoid or
reduce the impact of a collision in every situation. Over-reliance on this system to drive the vehicle
safely may lead to an accident resulting in death or serious injury.
