■ 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
assist. (

P.269) Therefore, even if the intu-
itive parking assist detects an object and
provides 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 cer-
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-

Intuitive parking assist buzzer
Regardless of whether the intuitive parking
assist system is enabled or not (

P.266), if
the Parking Support Brake function (static
objects) is enabled (

P.279), the front or
rear sensors detect an object and brake
control is performed, the intuitive parking
assist buzzer will sound to notify the driver
of the approximate distance to the object.
■ Situations in which the Parking Support
Brake function (static objects) may
operate even if there is no possibility of a
collision
In some situations, such as the following, the
Parking Support Brake function (static
objects) may operate even though there is
no possibility of a collision.
● Vehicle surroundings
• When driving on a narrow road
• When driving on a gravel road or in an
area with tall grass
