• Brake status
• Vehicle speed
• Operation status of the pre-collision

• Information (such as the distance and relative speed between your
vehicle and the vehicle ahead or
other objects)
• Images from the camera sensor
(available only when the pre-colli-
sion braking function or the pre-col-
lision brake assist function was
operating)
The pre-collision system does not
record conversations, sounds or
images of the inside of the vehicle.
 Data usageLexus may use the data recorded in this
computer to diagnose malfunctions, con-
duct research and development, and
improve quality.

• With the consent of the vehicle owner or
with the consent of the lessee if the vehi-

agency
• For use by Lexus in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle
owner

nition accuracy and control performance
that this system can provide, do not
overly rely on this system. The driver is
always responsible for paying attention
to the vehicle's surroundings and driving
safely.
