■The system can be operated when
● The power switch is in ON mode.
● Toyota parking assist-sensor function is on.
● The vehicle speed is less than about 10 km/h (6 mph).
● A shift lever other than P is selected.
● Vehicles with side sensors: Steering wheel is turned approximately 90° or
more
■ If “Parking assist unavailable. Clean parking assist sensor” is displayed
on the multi-information display
A sensor may be covered with ice, snow, dirt, etc. Remove the i ce, snow, dirt,
etc., from the sensor to return the system to normal.
Also, due to ice forming on a sensor at low temperatures, a war ning message
may be displayed or the sensor may not be able to detect an obj ect. Once the
ice melts, the system will return to normal.
■ If “Parking assist Malfunction Visit your dealer” is displayed on the
multi-information display
The system may not operate due to the malfunction of a sensor.
Have the vehicle inspected by any authorized Toyota retailer or Toyota autho-
rized repairer, or any reliable repairer.
■ Sensor detection information
The following situations may occur during use.
● The sensors may be able to only detect objects near the front and rear bum-
pers.
● Depending on the shape of the object and other factors, the detection dis-
tance may shorten, or detection may be impossible.
● If an object is extremely close to a sensor, it may not be detected.
● There will be a short delay between object detection and display. Even at
low speeds, there is a possibility that the object will come wi thin the sensor’s
detection areas before the display is shown and the warning bee p sounds.
● It might be difficult to hear the buzzer due to the volume of the audio system
or air flow noise of the air conditioning system.
● It may be difficult to hear the buzzer if buzzers for other systems are sound-
ing.

PKSB (Parking Suppor t Brake)
■Parking Support Brake function (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. 483)
■Parking Support Brake function (rear-crossing vehicles) (if
equipped)
Rear radar sensors are used to detect approaching vehicles in t he
detection area behind the vehicle when backing up. ( P. 4 8 7 )
: If equipped
The 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 is high, a warning operates to
urge the driver to take evasive action. If the system determine s
that the possibility of a collision with a detected object 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 ac cident.
Always drive while checking the safety of the surroundings of t he vehicle.
Depending on the vehicle and road conditions, weather, etc., th e 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 Brak e system
is designed to provide support to lessen the severity of collis ions. 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 ve hicle, it is
necessary to depress the brake pedal immediately as brake contr ol 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 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 addi tional 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, compact spare tire or an emergency tire puncture
repair kit is used

Parking Support Brake function (static
objects)
This function will operate in situations such as the following if an
object is detected in the traveling direction of the vehicle.
■When traveling at a low speed and the brake pedal is not
depressed, or is depressed late
: If equipped
If the sensors detect a static object, such as a wall, in the t ravel-
ing direction of the vehicle and the system determines that a c ol-
lision may occur due to the vehicle suddenly moving forward
due to an accidental accelerator pedal operation, the vehicle
moving the unintended direction due to the wrong shift lever
being selected, or while parking or traveling at low speeds, th e
system will operate to lessen the impact with the detected stat ic
object and reduce the resulting damage.
