WARNING
■Cautions regarding the use of
the 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 vehi-cle.
Depending on the vehicle and road conditions, weather, etc., the system may not operate.
The detection capabilities of sensors and radars are limited. Always drive while checking the safety of the sur-
roundings of the vehicle.
●The driver is solely responsible for
safe driving. Always drive carefully, taking care to observe your sur-roundings. The Parking Support
Brake system is designed to pro- vide support to lessen the severity of collisions. However, 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.
●It is extremely dangerous to check
the system operations by intention- ally driving the vehicle into the direction of a wall, etc. Never
attempt such actions.
■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 automatic car washing devices
●If the vehicle cannot be driven in a stable manner, such as when the vehicle 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
■Precautions for the suspension
Do not modify the suspension of the vehicle. If the height or tilt of the vehi-cle is changed, the sensors may not
be able to detect detectable objects and the system may not operate cor-rectly, possibly leading to an accident.

■If the Parking Support Brake has operated
If the vehicle is stopped due to operation of the Parking Support Brake, the Park-ing Support Brake will be disabled and
the driving assist information indicator will illuminate. If the Parking Support Brake operates unnecessarily, brake
control can be canceled by depressing the brake pedal or waiting for approxi-mately 2 seconds for it to automatically
be canceled. Then, the vehicle can be operated by depressing the accelerator pedal.
■Re-enabling the Parking Support
Brake
To re-enable the Parking Support Brake when it has been disabled due to opera-
tion of the Parking Support Brake, either
enable the system again ( P.354), or turn the power switch off and then back to ON.
Additionally, if any of the following condi- tions are met, the system will be re-enabled automatically and the driving
assist information indicator will turn off:
●The P shift position is selected
●The object is no longer detected in the traveling direction of the vehicle
●The traveling direction of the vehicle
changes*
*: Except when the Pedestrian Rear of
the Vehicle operated.
■Toyota parking assist-sensor
buzzer
Regardless of whether the Toyota park- ing assist-sensor buzzer is enabled or
not, if the PKSB (Parking Support Brake) system is enabled, the front or rear sensors detect a static object and
brake control is performed, the Toyota parking assist-sensor buzzer will sound to notify the driver of the approximate
distance to the object.
■If a 12-volt battery terminal has been disconnected and recon-nected
The system needs to be initialized. To initialize the system, drive the vehicle straight ahead for 5 seconds or more at
a speed of approximately 35 km/h (22 mph) or more.

This function will operate in situa-
tions such as the following if an
object is detected in the traveling
direction of the vehicle.
■When traveling at a low speed

Static Objects Front and
Rear of the Vehicle*
If the sensors detect a static
object, such as a wall, in the
traveling direction of the vehi-
cle and the system determines
that a collision may occur due
to the vehicle suddenly mov-
ing forward due to an acciden-
tal accelerator pedal operation,
the vehicle moving the unin-
tended direction due to the
wrong shift position being
selected, or while parking or
traveling at low speeds, the
system will operate to lessen
the impact with the detected
static object and reduce the
resulting damage.

■The system will operate when
The function will operate when the driv-
ing assist information indicator is not illu- minated ( P.169, 519) and all of the following conditions are met:
●EV system output restriction control• 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
brake operation is necessary to avoid a collision.
●Brake control• EV system output restriction control is operating.
• The Parking Support Brake deter- mines that an immediate brake opera-tion is necessary to avoid a collision.
■The system will stop operating
when
The function will stop operating if any of the following conditions are met:
●EV system output restriction control• 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
The detection range of the system dif- fers from the detection range of the
Toyota parking assist-sensor. ( P.337)
Therefore, even if the Toyota parking assist-sensor detects a static and pro-
vides a warning, the PKSB (Parking Support Brake) system may not start

■Sensor detection information
The detection range of the system dif- fers from the detection range of the Toyota parking assist-sensor.
Therefore, even if the Toyota parking assist-sensor detects a static object and provides a warning, the PKSB (Parking
Support Brake) system may not start operating.
■Objects which the sensor may not be properly detected

■Situations in which the system may
operate even though there is no possibility of a collision
In addition to the situations in which sta-
tionary objects around the vehicle ( P.358) may not be detected, objects may not be detected by the sensors in
the following situations
When moving sideways, such as when parallel parking: P.359
■Detection of objects along the
sides of the vehicle
●Objects along the sides of the vehicle
are not instantaneously detected. The location of objects in relation to the vehicle is estimated after they are first
detected by the front or rear side sen- sors, or side cameras. Therefore, after the power switch is changed to ON,
even if an object is along the side of the vehicle, it may not be detected until the vehicle has been driven a
small amount and the side sensors or side cameras completely scan the areas along the sides of the vehicle.
