■The windshield wiper and washer can be operated when
Vehicles without a smart entry & start system
The engine switch is in the “ON” position.
Vehicles with a smart entry & start system
The engine switch is in IGNITION ON mode.
■ Effects of vehicle speed on wiper operation (vehicles with rain-sensing
windshield wipers)
Even when the wipers are not in “AUTO” mode, wiper operation varies
depending on vehicle speed when the washer is being used (delay until drip
prevention wiper sweep occurs).
■ Raindrop sensor (vehicles with rain-sensing windshield wipers)
● If the wiper switch is turned to the “AUTO” position while the engine switch is
in IGNITION ON mode, the wiper will operate once to show that “AUTO”
mode is activated.
● If the temperature of the raindrop sensor 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”.
■ 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.
● 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 windshield.

PCS (Pre-Collision System)
: If equipped
The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedestrians* in front of your vehicle.
When the system determines that the possibility of a frontal col-
lision with a vehicle or pedestrian 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 frontal collision with
a vehicle or pedestrian is extremely high, the brakes are auto-
matically 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. 302)
*: Depending on the region in which the vehicle was sold, the pedestrian
detection function may not be available. Contact any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer for details.
