■ Detection range of the Parking Support
Brake function (static objects)
The detection range of the Parking Support
Brake function (static objects) differs from
the detection range of the intuitive parking

tive parking assist detects an object and
provides a warning, the Parking Support
Brake function (static objects) may not start
operating.

function (static objects) may not detect

tain objects, such as the following:
●
Pedestrian
●
Cotton cloth, snow, and other materials
that are poor reflectors of ultrasonic
waves
●
Objects which are not perpendicular to
the ground, are not perpendicular to the
traveling direction of the vehicle, are
uneven or are waving
●
Low objects
●
Thin objects such as wires, fences, ropes
and signposts
●
Objects that are extremely close to the
bumper
●
Sharply-angled objects
●
Tall objects with upper sections project-
