The pre-collision system is equipped with a sophisticated computer that will
record certain data, such as: • How far (if at all) the driver was depressing the accelerator and/or brake pedal
• Vehicle speed
• Operation status of the pre-collision system functions
• Information (such as the distance and relative speed between your vehicle and the vehicle ahead or other objects)
Additionally, if the pre-collision braking fu nction is operating, image information
from the camera sensor will also be recorded. The pre-collisio n system does not
record conversations, sounds or pictures.
●Data usage
Lexus may use the data recorded in this computer to diagnose malfunctions,
conduct research and development, and improve quality.
Lexus will not disclose the recorded data to a third party except: • With the consent of the vehicle owner or with the consent of the lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a govern- ment agency
• For use by Lexus in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner
●Recorded image information can be erased using a specialized device.
The image information recording function can be disabled. However, if the
function is disabled, data from when the pre-collision system operates will not
be available.
