*
Brake) system
*
: If equipped
The PKSB (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
determines 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.
The system can detect the following as
detectable objects. (Detectable
objects differ depending on the func-
tion.)
 Parking Support Brake (Static
Objects Front and Rear of the vehi-
cle) (P.368)
 Parking Support Brake (Moving

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.
The driver is solely responsible for safe
driving. Always drive carefully, taking
care to observe your surroundings.
The PKSB (Parking Support Brake)
system is designed to provide support
to lessen the severity of collisions.
However, it may not operate in some
situations.
The PKSB (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.
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 PKSB (Parking
Support Brake) system
In the following situations, disable the
PKSB (Parking Support Brake) as the
system may operate even though there is
no possibility of a collision.
