The Parking Support Brake system
consists of the following functions
that operate when driving at a low
speed or backing up, such as when
parking. When the system deter-
mines that a collision with a
detected object or pedestrian is
high, a warning operates to urge
the driver to take evasive action. If
the system determines that the pos-
sibility of a collision with a detected
object or pedestrian is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.

WARNING
■
Cautions regarding the use of the sys-
tem
Do not overly rely on the system, as
doing so may lead to an accident. Always
drive while checking the safety of the sur-
roundings of the vehicle.
Depending on the vehicle and road con-
ditions, weather, etc., the system may not
operate.
The detection capabilities of sensors,
radars and camera are limited. Always
drive while checking the safety of the sur-
roundings of the vehicle.
●
Do not attempt to test the operation of
this system by driving the vehicle
toward another vehicle, a person or
detected object, as it may not operate
properly, possibly leading to an acci-
dent.
●
The driver is solely responsible for safe
driving. Always drive carefully, taking
care to observe your surroundings.
The Parking Support Brake system is
designed to provide support to lessen
the severity of collisions. However, it
may not operate in some situations.
●
The Parking Support Brake system is
not designed to stop the vehicle com-
pletely. Additionally, even if the system
has stopped the vehicle, it is necessary
to depress the brake pedal immedi-
ately as brake control will be canceled
after approximately 2 seconds.
●
It is extremely dangerous to check the
system operations by intentionally
driving the vehicle into the direction of
a wall, etc. Never attempt such actions.

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