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.

■ Objects that the Parking Support Brake func tion (static objects) may not
detect
The sensors may not be able to detect certain objects, such as the following.
● Pedestrian
● Cotton cloth, snow, and other materials that are poor reflector s of ultrasonic
waves.
(People may also not be detected depending on the type of cloth ing they are
wearing.)
● Objects which are not perpendicular to the ground, are not perp endicular to
the traveling direction of the vehicle, are uneven or are wavin g.
● Low objects
● Thin objects such as wires, fences, ropes and signposts
● Objects that are extremely close to the bumper
● Sharply-angled objects
● Tall objects with upper sections projecting outwards in the dir ection of your
vehicle
■ Situations in which the Parking S upport Brake may not operate properly
When the shift lever is in N
■ Intuitive parking assist buzzer
Regardless of whether the intuitive parking assist system is en abled or not
( P. 342), if the Parking Support Brake system is enabled ( P. 362), 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. 362). 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.

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 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

Re-enabling the Parking Suppor t Brake function (rear-crossing v ehicles)
To re-enable the Parking Support Brake function (rear-crossing vehicles)
when it is disabled while it is operating, either enable the Pa rking Support
Brake system again ( P. 362), or turn the engine switch off and then back to
IGNITION ON mode. When the function is disabled, the PKSB OFF i ndicator
will illuminate. ( P. 89)
If there is no longer a vehicle approaching from the right or l eft at the rear of
the vehicle when backing up, or if the traveling direction of the vehicle
changes (such as changing from backing up to moving forward), the system
will be re-enabled automatically. When the function is re-enabl ed, the PKSB
OFF indicator will turn off.
■ Conditions under which the Parki ng Support Brake function (rear-cross-
ing vehicles) will not detect a vehicle
The Parking Support Brake function (rear-crossing vehicles) is not designed
to detect the following types of vehicles and/or objects:
● Vehicles approaching from directly behind
