■Detection range of the Parking Sup -
port Brake function (static objects)
The detection range of the Parking Sup -
port Brake function ( static objects) dif-
fers from the detection range of the Toyota parking assist-sensor. ( →P.418)
Therefore, even if the Toyota parking
assist-sensor detect s an object and pro-
vides a warning, the Parking Support Brake function (static objects) may not
start operating.
■Objects that the Parking Support
Brake function (static objects) may not detect
The sensors may not be able to detect
certain objects, such as the following:
