PKSB (Parking Sup-

port Brake)

The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
probability of a collision
with a detected object or
pedestrian is high, a warn-
ing operates to urge the
driver to take evasive
action. If the system deter-
mines that the possibility 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 collision.

PKSB (Parking Support
Brake) system

WARNING

■

Cautions regarding the use of

the system

Do not overly rely on the system,

as doing so may lead to an acci-

dent.
Always drive while checking the

safety of the surroundings of the

vehicle.
Depending on the vehicle and

road conditions, weather, etc., the

system may not operate.
The detection capabilities of sen-

sors and radars are limited.

Always drive while checking the

safety of the surroundings of the

vehicle.

●

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 sys-

tem is not designed to stop the

vehicle completely. Additionally,

even if the system has stopped

the vehicle, it is necessary to

depress the brake pedal imme-

diately 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.

■

When to disable the Parking

Support Brake

In the following situations, disable

the Parking Support Brake as the

system may operate even though

there is no possibility of a colli-

sion.

NOTICE

●

In panoramic view/moving

view/see-through view, the sys-

tem combines images taken

from the front, back, left and

right side cameras into a single

image. There are limits to the

range and content that can be

displayed. Familiarize yourself

with the characteristics of the

panoramic view monitor system

before using it.

●

Image clarity may decline at the

four corners of the panoramic

view/moving view/see-through

view. However, this is not a mal-

function, as these are the

regions along the border of

each camera image where the

images are combined.

●

Depending on lighting condi-

tions near each of the cameras,

bright and dark patches may

appear on the panoramic

view/moving view/see-through

view.

●

The panoramic view/moving

view/see-through view display

does not extend higher than the

installation position and image

capture range of each camera.

●

There are blind spots around

the vehicle. Accordingly, there

are regions not displayed in

panoramic view.

●

NOTICE

●

People and other three-dimen-

sional obstacles may appear

differently when displayed on

the panoramic view monitor.

(These differences include,

among others, cases in which

displayed objects appear to

have fallen over, disappear near

image processing areas, appear

from image processing areas,

or when the actual distance to

an object differs from the dis-

played position.)

●

When the back door, which is

equipped with the back camera,

or front doors, which are

equipped with door mirrors that

have built-in side cameras, are

open, images will not be dis-

played properly on the pan-

oramic view monitor.

●

The vehicle icon displayed in

panoramic view/moving

view/see-through view is a com-

puter generated image. Accord-

ingly, properties such as the

color, shape and size will differ

from the actual vehicle. For this

reason, nearby three-dimen-

sional objects may appear to be

touching the vehicle, and actual

distances to three-dimensional

objects may differ from those

displayed.
