■Parking Support Brake f unction (static objects)
Ultrasonic sensors are used to detect static objects, such as a wall,
in the detection area when driving at a low speed or backing up .
( P. 348)
■Parking Support Brake function (rear-crossing vehicles)
Rear radar sensors are used to detect approaching vehicles in t he
detection area behind the v ehicle when backing up. (P. 352)
PKSB (Parking Suppor t Brake)
: If equipped
The Parking Support Brake system consists of the following
functions that operate when dr iving 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 wa rning
operates to urge the driver to take evasive action. If the syst em
determines that the possibility of a collision with a detected
object is extremely high, the br akes are automatically applied to
help avoid the collision or help reduce the impact of the colli -
sion.

■If the Parking Support B rake function has operated
If the vehicle is stopped due to operation of the Parking Suppo rt Brake func-
tion, the Parking Support Brake system will be disabled and the PKSB OFF
indicator will illuminate. If the Parking Support Brake operates unnecessarily,
brake control can be canceled by depressing the brake pedal or waiting for
approximately 2 seconds for it to automatically be canceled. Then, the vehicle
can be operated by depressing the accelerator pedal.
■ Re-enabling the Park ing Support Brake system
To re-enable the Parking Support Brake system when it is disabl ed due to
operation of the Parking Support Brake function, either enable the system
again ( P. 341), or turn the power switch off and then back to ON mode.
Additionally, if the object becomes no longer in the traveling direction of the
vehicle or if the traveling direction of the vehicle changes (such as changing
from moving forward to backing up, or from backing up to moving forward),
the system will be re-enabled automatically.
■ If “PKSB Unavailable” and “Park ing Assist Unavailable Clean Parking
Assist Sensor” are displayed on th e multi-information display and the
PKSB OFF indicator is illuminating
● A sensor may be covered with ice, snow, dirt, etc. In this case , remove the
ice, snow, dirt, etc., from the sensor to return the system to normal. If this
message is shown even after removing dirt from the sensor, or s hown when
the sensor was not dirty to begin with, have the vehicle inspec ted at your
Toyota dealer.
● A sensor may be frozen. Once the ice melts, the system will ret urn to nor-
mal.
● Water may be continuously flowing over the sensor surface, such as in a
heavy rain. When the system determines that it is normal, the system will
return to normal.

WARNING
■Cautions 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 vehicle.
Depending on the vehicle and road conditions, weather, etc., the system
may not operate.
The detection capabilities of sensors and radars are limited. A lways drive
while checking the safety of the surroundings of the vehicle.
● The driver is solely responsible for safe driving. Always drive carefully, tak-
ing care to observe your surroundings. The Parking Support Brake system
is designed to provide support to lessen the severity of collisions. How-
ever, it may not operate in some situations.
● The 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 int entionally
driving the vehicle into the direction of a wall, etc. Never at tempt 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 collision.
● 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 vehi-
cle has been in an accident 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
● When a tire chains or compact spare tire is used
