■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 Parkin g 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. 346), 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 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

WARNING
■Limitations of the Par king 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 power switch is turned to
ON mode, operate the vehicle carefully, paying attention to your surround-
ings. It may be necessary to drive the vehicle for a certain am ount of time
before the system returns to normal. (If the system is not return to normal
after driving for a while, clean the sensors and their surrounding area on the
bumpers.)

3524-5. Using the driving support systems
The system will operate in situat ions 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
Parking Suppor t Brak e function (static
objects)

: If equipped
If a collision with an object ma y occur due to the vehicle sud-
denly moving forward due to an accidental accelerator pedal
operation, the vehicle moving th e unintended direction due to
the wrong shift position being se lected, or while parking or trav-
eling at low speeds, the sensors detect objects, such as a wall ,
in the traveling direction of t he vehicle, and the system opera tes
to lessen an impact with an object and reduce the resulting dam -
age.

Regardless of whether the intuitive parking assist system is en abled or not
( P. 327), if the Parking Support Brake system is enabled ( P. 346), the
front or rear sensors detect an object and brake control is performed, the intu-
itive parking assist buzzer will sound to notify the driver of the approximate
distance to the object.

WARNING
■To ensure the Parking Support Brake can operate properly
Observe the following precautions regarding the sensors ( P. 346). Failure
to do so may cause a sensor to not operate properly, and may cause an
accident.
● Do not modify, disassemble or paint the sensors.
● Do not replace a sensor with a part other than a genuine part.
● Do not subject a sensor or its surrounding area to a strong impact.
● Do not damage the sensors, and always keep them clean.
● If the area around a sensor is subjected to an impact, the system may not
operate properly due to the sensor being misaligned. Have the vehicle
inspected by your Toyota dealer.
■ Handling the suspension
Do not modify the suspension, as changes to the height or inclination of the
vehicle may prevent the sensors from detecting objects correctly or cause
the system to not operate or operate unnecessarily.
■ If the Parking Support Brake function (static objects) operates unnec-
essarily, such as at a railroad crossing
In the event that the Parking Support Brake function (static ob jects) oper-
ates unnecessarily, such as at a railroad crossing, brake contr ol will be can-
celed after approximately 2 seconds, allowing you to proceed forward and
leave the area, brake control can also be canceled by depressing the brake
pedal. Depressing the accelerator pedal after brake control is canceled will
allow you to proceed forward and leave the area.
