●
Brake control
• Engine output restriction control is
operating
• The Parking Support Brake deter-
mines that an immediate brake opera-
tion is necessary to avoid a collision.
■ The Parking Support Brake func-
tion (static objects) will stop oper-
ating when
The function will stop operating if any of
the following conditions are met:
● Engine output restriction control
• The Parking Support Brake is dis-
abled.
• The system determines that the colli-
sion has become avoidable with nor-
mal brake operation.
• The static object is no longer 2 to 4 m
(6 to 13 ft.) away from the vehicle or in
the traveling direction of the vehicle.
● Brake control
• The Parking Support Brake is dis-
abled.
• Approximately 2 seconds have
elapsed since the vehicle was
stopped by brake control.
• The brake pedal is depressed after
the vehicle is stopped by brake con-
trol.
• The static object is no longer 2 to 4 m
(6 to 13 ft.) away from the vehicle or in
the traveling direction of the vehicle.
■ 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.322)
Therefore, even if the Toyota parking
assist-sensor detects 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:
● Pedestrian
●
Cotton, snow, and other materials that
are poor reflectors of sonic 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 pro-
jecting outwards in the direction of
your vehicle

Situations in which the Parking
Support Brake function (static
objects) may not operate
When the shift lever is in N
■ Toyota parking assist-sensor
buzzer
Regardless of whether the Toyota park-
ing assist-sensor function is enabled or
not (P.320), if the Parking Support
Brake function (static objects) is enabled
(P.327), the front or rear sensors
detect an object and brake control and
engine output restriction control are per-
formed, the Toyota parking assist-sen-
sor 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 follow-
ing, the Parking Support Brake function
(static objects) may operate even
though there is no possibility of a colli-
sion.
