WARNING
■To ensure the Parking Support
Brake can operate properly
Observe the following precautions regarding the sensors ( P.414). Fail-
ure 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 sur-rounding area to a strong impact.
●Do not damage the sensors, and always keep them clean.

when
The function will operate when the PKSB OFF indicator is not illuminated
( P.170, 171) and all of the following conditions are met:
●Hybrid system output restriction con-trol
• The Parking Support Brake is enabled.• The vehicle speed is approximately 15
km/h (9 mph) or less. • There is a static object in the traveling direction of the vehicle and approxi-
mately 2 to 4 m (6 to 13 ft.) away. • The Parking Support Brake deter-mines that a stronger-than-normal

WARNING
●If the area around a radar sensor is subjected to an impact, the system
may not operate properly due to a sensor malfunction. Have the vehi-cle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■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 unnecessarily, such as at a rail-road crossing
In the event that the Parking Support Brake function (static objects) oper-ates unnecessarily, such as at a rail-
road crossing, brake control will be canceled after approximately 2 sec-onds, allowing you to proceed forward
and leave the area, brake control can also be canceled by depressing the brake pedal. Depressing the acceler-
ator pedal after brake control is can- celed will allow you to proceed forward and leave the area.
■Notes when washing the vehicle
Do not apply intensive bursts of water
or steam to the sensor 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 malfunc-tion.
●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 Sup-port 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 modi-
fied 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 tow-ing eyelet, bumper protector (an
additional trim strip, etc.), bicycle carrier, or snow plow
●When using an automatic car wash

• The Parking Support Brake deter-
mines that an immediate brake opera-
tion is necessary to avoid a collision.
■The Parking Support Brake func-
tion (static objects) will stop oper-
ating when
The function will stop operating if any of
the following conditions are met:
●Hybrid system output restriction con-
trol
• The Parking Support Brake is dis-
abled.
• The system determines that the colli-
sion has become avoidable with nor-
mal brake operation.
• The static object is no longer approxi-
mately 2 to 4 m (6 to 13 ft.) away from
the vehicle or in the traveling direction
of the vehicle.
●Brake control
• The Parking Support Brake is dis-
abled.
• Approximately 2 seconds have
elapsed since the vehicle was
stopped by brake control.
• The brake pedal is depressed after
the vehicle is stopped by brake con-
trol.
• The static object is no longer approxi-
mately 2 to 4 m (6 to 13 ft.) away from
the vehicle or in the traveling direction
of the vehicle.
■Detection range of the Parking Sup-
port Brake function (static objects)
The detection range of the Parking Sup-
port Brake function (static objects) dif-
fers from the detection range of the
Toyota parking assist-sensor. (P.418)
Therefore, even if the Toyota parking
assist-sensor detects an object and pro-
vides a warning, the Parking Support
Brake function (static objects) may not
start operating.
■Objects that the Parking Support
Brake function (static objects) may
not detect
The sensors may not be able to detect
certain objects, such as the following:
●Pedestrian
●Cotton, snow, and other materials that
are poor reflectors of sonic waves
●Objects which are not perpendicular
to the ground, are not perpendicular to
the traveling direction of the vehicle,
are uneven or are waving
●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 pro-
jecting outwards in the direction of
your vehicle
■Situations in which the Parking
Support Brake function (static
objects) may not operate
When the shift lever is in N
■Toyota parking assist-sensor
buzzer
Regardless of whether the Toyota park-
ing assist-sensor function is enabled or
not (P.415), if the Parking Support
Brake function (static objects) is enabled
(P.421), the front or rear sensors
detect an object and brake control and
hybrid system output restriction control
are performed, the Toyota parking
assist-sensor buzzer will sound to notify
the driver of the approximate distance to
the object.
■Situations in which the Parking
Support Brake function (static
objects) may operate even if there
is no possibility of a collision
In some situations, such as the follow-
ing, the Parking Support Brake function
(static objects) may operate even
though there is no possibility of a colli-
sion.
