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.

●EV system output restriction control• The Parking Support Brake is enabled.
• The vehicle speed is approximately 15 km/h (9 mph) or less.• Vehicles are approaching from the
right or left at the rear of the vehicle at a traveling speed of approximately 8 km/h (5 mph) or more.
• The shift position is in R. • The Parking Support Brake deter-mines that a stronger than normal
brake operation is necessary to avoid a collision with an approaching vehi-cle.
●Brake control• EV system output restriction control is
operating. • The Parking Support Brake deter-mines that an emergency brake oper-
ation is necessary to avoid a collision with an approaching vehicle.
■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 collision becomes avoidable with normal brake operation.• A vehicle is no longer approaching

• 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.• A vehicle is no longer approaching
from the right or left at the rear of the vehicle.
■Detection range
The detection range of the moving vehi-
cles rear of the vehicle differs from the detection area of the RCTA function ( P.344). Therefore, even if the RCTA
function detects a vehicle and provides an alert, the moving vehicles rear of the vehicle may not start operating.
■RCTA buzzer
Regardless of weather the RCTA func- tion is on or off, if the PKSB (Parking Support Brake) system is not disabled,
when the brake control operates, the buzzer will sounds to alert the driver.
