■Lexus parking assist-sensor buzzer
Regardless of whether the Lexus parking 
assist-sensor buzzer is enabled or not 
(  P.248), if the Parking Support Brake 
function (static objects) is enabled 
(  P.254), the front or  rear sensors detect 
an object and brake control is performed, 
the Lexus parking assist-sensor buzzer will 
sound to notify the driver of the approxi-
mate distance to the object.
■In the unlikely event that the Parking 
Support Brake function (for static 
objects) mistakenly operates at a cross-
ing or elsewhere
Even in the unlikely  event that the Parking 
Support Brake function (for static objects) 
mistakenly operates at a crossing or else-
where, brake control is canceled after 
approximately 2 seconds, allowing you to

detected in are outlined below.
The range of the detection area extends to:
Approximately 11.5 ft. (3.5 m) from 
the side of the vehicle
The first 1.6 ft. (0.5 m) from the side of the 
vehicle is not in the detection area
Approximately 9.8 ft. (3 m) from

not function correctly. Therefore the 
driver’s own visual confirmation of safety 
is necessary.
