PKSB (Parking Support
Brake)*
The Parking Support Brake
system consists of the follow-
ing functions that operate
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 oper-
ates to urge the driver to take
evasive action. If the system
determines that the possibility
of a collision with a detected
object is extremely high, the
brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.

Brake) system
WARNING
QCautions regarding the use of the system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the
safety of the surroundings of the vehi- cle.
Depending on the vehicle and road
conditions, weather, etc., the system may not operate.
The detection capabilities of sensors
and radars are limited. Always drive while checking the safety of the sur-roundings of the vehicle.
OThe driver is solely responsible for safe driving. Always drive carefully,
taking care to observe your sur- roundings. The Parking Support Brake system is designed to pro-
vide support to lessen the severity of collisions. However, it may not operate in some situations.
OThe Parking Support Brake system 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 immediately as brake control will be canceled after approximately 2 seconds.
OIt is extremely dangerous to check the system operations by intention-
ally driving the vehicle into the direction of a wall, etc. Never attempt such actions.
QWhen to disable the Parking Sup-port Brake
In the following situations, disable the Parking Support Brake as the system may operate even though there is no
possibility of a collision.
OWhen inspecting the vehicle using
a chassis roller, chassis dynamo or free roller.

3805-5. Using the driving support systems

function (static objects)
*
If the sensors detect a static
object, such as a wall, in the
traveling direction of the vehi-
cle and the system determines
that a collision may occur due
to the vehicle suddenly moving
forward due to an accidental
accelerator pedal operation,
the vehicle moving the unin-
tended 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.
