WARNING
■Sensors
Certain vehicle conditions and the surrounding environment may affect the
ability of a sensor to correctly detect an object. Particular instances where
this may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors w ill resolve
this problem.)
● The sensor is frozen. (Thawing the area will resolve this probl em.)
In especially cold weather, if a sensor is frozen the screen may show an
abnormal display, or objects may not be detected.
● The sensor is covered in any way.
● The vehicle is leaning considerably to one side.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● The vicinity of the vehicle is noisy due to vehicle horns, moto rcycle
engines, air brakes of large vehicles, or other loud noises pro ducing ultra-
sonic waves.
● There is another vehicle equipped with parking assist sensors in the vicin-
ity.
● The sensor is coated with a sheet of spray or heavy rain.
● The sensor is drenched with water on a flooded road.
● The vehicle is equipped with a fender pole, wireless antenna or fog lights.
● The bumper or sensor receives a strong impact.
● The vehicle is approaching a tall or curved curb.
● The detection range is reduced due to an object such as a sign.
● In harsh sunlight or intense cold weather.
● The area directly under the bumpers is not detected.
● If objects draw too close to the sensor.
● A non-genuine Toyota suspension (lowered suspension, etc.) is installed.
● A backlit license plate is installed.
In addition to the examples above, there are instances in which , because of
their shape, signs and other objects may be judged by a sensor to be closer
than they are.

WARNING
■Objects which may not be properly detected
The shape of the object may prevent a sensor from detecting it. Pay partic-
ular attention to the following objects:
● Wires, fences, ropes, etc.
● Cotton, snow and other materials that absorb sound waves
● Sharply-angled objects
● Low objects
● Tall objects with upper sections projecting outwards in the direction of your
vehicle
● People may not be detected if they are wearing certain types of clothing.
■ When using intuitive parking assist
In the following situations, the system may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by your Toyota dealer.
● The intuitive parking assist operation display flashes, and a buzzer sounds
when no objects are detected.
● If the area around a sensor collides with something, or is subjected to
strong impact.
● If the bumper collides with something.
● If the display shows continuously without beeping, except when the buzzer
volume is muted.
● If a display error occurs, first check the sensor.
If the error occurs even if there is no ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■ Notes when washing the vehicle
Do not apply intensive bursts of water or steam to the sensor a rea.
Doing so may result in the sensor malfunctioning.
● When using a high pressure washer to wash the vehicle, do not spray the
sensors directly, as doing so may cause a sensor to malfunction .
● When using steam to clean the vehicle, do not direct steam too close to
the sensors as doing so may cause a sensor to malfunction.
● When using an automatic car wash, disable the intuitive parking assist

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. 368)
■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. 377)
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.
■ Re-enabling the Parking 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. 362), or turn the engine switch off and then back to IGNITIO N 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 flashing
● 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
■Limitations of the Parking Support Brake 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.
NOTICE
■If “PKSB Unavailable” is displayed on the multi-information dis play
and the PKSB OFF indicator is flashing
If this message is displayed immediately after the engine switch is changed
to ON, operate the vehicle carefully, paying attention to your surroundings.
It may be necessary to drive the vehicle for a certain amount of time before
the system returns to normal. (If the system is not return to n ormal after
driving for a while, clean the sensors and their surrounding area on the
bumpers.)
