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.

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 capa bilities 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 Suppor t Brake as the
system may opera te even though
there is no possibility of a colli-
sion.
●When inspecting the vehicle
using a chassis roller, chassis
dynamo or free roller
●When loading the vehicle onto a
boat, truck or other transport
vessel
●If the suspension has been
modified or tires of a size other
than specified are installed
●If the front of the vehicle is
raised or lowered due to the
carried load
●When equipment that may
obstruct a sensor is installed,
such as a towing eyelet, bumper
protector (an additional trim
strip, etc.), bicycle carrier, or
snow plow
●When using automatic car
washing devices
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning
●When the vehicle is driven in a
sporty manner or off-road
●When the tires are not properly
inflated
●When the tires are very worn

If the sensors detect a static
object, such as a wall, in the
traveling direction of the
vehicle and the system
determines that a collision
may occur due to the vehi-
cle 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.
