SORY mode and the driver's door is opened while the lights are turned on.
■ Windshield wiper linked h eadlight illumination
When driving during daytime with the headlight switch turned to , if the
windshield wipers are used, the headlights will turn on automat ically after
several seconds to help enhance the visibility of your vehicle. The sensor may not function properly if an
object is placed on the sensor, or anything
that blocks the sensor is affixed to the
windshield.
Doing so interferes with the sensor
detecting the level of ambient light and
may cause the automatic headlight sys-
tem to malfunction.

2304-5. Using the driving support systems
The pre-collision system is equipped with a sophisticated compu ter
that will record certain data, such as: • Accelerator status
• Brake status
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the dist ance and relative speed between y our
vehicle and the vehicle ahead or other objects)
• Images from the camera sensor (available only when the pre-col li-
sion braking function or the pre-collision brake assist functio n was
operating)
The pre-collision system does not record con versations, sounds or
images of the inside of the vehicle.
● Data usage
Toyota may use the data recorded in this computer to diagnose
malfunctions, conduct research and development, and improve
quality.
Toyota will not disclose the recorded data to a third party exc ept:
• With the consent of the vehicle owner or with the consent of t he
lessee if the vehicle is leased
• In response to an official request by the police, a court of l aw or a
government agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner
● Recorded images can be erased using a specialized device.
The image recording function can be disabled. However, if the f unc-
tion is disabled, data from when the pre-collision system opera tes
will not be available.

2364-5. Using the driving support systems
◆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.
◆Pre-collision brake assist
When the system determines that the possibility of a frontal colli-
sion is high, the system applies greater braking force in relat ion to
how strongly the brak e pedal is depressed.
◆Pre-collision braking
When the system determines that the possibility of a frontal colli-
sion is high, the system warns the driver. If the system determ ines
that the possibility of a frontal collision is extremely high, the brakes
are automatically applied to hel p avoid the collision or reduce the
collision speed.
PCS (Pre-Collision System)
The pre-collision system uses a radar sensor and camera sen-
sor to detect vehicles and pedest rians in front of your vehicle.
When the system determines that t he possibility of a frontal col-
lision with a vehicle or pedest rian 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 possi bility 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 th e
impact of the collision.
The pre-collision system can b e disabled/enabled and the warnin g
timing can be changed. ( P. 2 3 9 )
