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
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically 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. Addition-

ally, even if the system has

stopped the vehicle, it is neces-

sary to depress the brake pedal

immediately as brake control

will be canceled after approxi-

mately 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.

Parking Support Brake function (static objects)

If the sensors detect a static object, such as a wall, in the trav-
eling direction of the vehicle and the system determines that
a collision may occur due to the vehicle suddenly moving for-
ward due to an accidental accelerator pedal operation, the
vehicle moving the unintended direction due to the wrong
shift position being selected, or while parking or traveling at
low speeds, the system will operate to lessen the impact with
the detected static object and reduce the resulting damage.
