5-4. Using the driving support systems
The Parking Support Brake can be
enabled/disabled on the multi-infor-
mation display. All of the Parking
Support Brake functions (static
objects front and rear of the vehicle,
moving vehicles rear of the vehicle,
pedestrians rear of the vehicle and
static objects around the vehicle)
are enabled/disabled simultane-
ously.
Use the meter control switches to
enable/disable the parking support
brake. ( P.176)
1 Press or to select .
2 Press or to select “
PKSB” and then press .
When the Parking Support Brake is dis- abled, the driving assist information
indicator ( P.169) illuminates.
To re-enable the system when it was
disabled, select on the multi-infor-
mation display, select “ PKSB” and
then On. If disabled using this method,
the system will not be re-enabled by
turning the power switch off and then to
ON.
If the EV system output restriction con-
trol or brake control operates, a buzzer
will sound and a message will be dis-
played on the multi-information display
and multimedia system screen, to alert
the driver.
Depending on the situation, EV system
output restriction control will operate to
either limit acceleration or restrict out-
put as much as possible.

If the Parking Support Brake deter-
mines that a collision with a
detected object or pedestrian is
possible, the EV system output will
be restricted to restrain any
increase in the vehicle speed. (EV
system output restriction control:
See figure 2.)
Additionally, if the accelerator pedal
continues to be depressed, the
brakes will be applied automatically
to reduce the vehicle speed. (Brake
control: See figure 3.)

■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.

*: If equipped
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
and the brake pedal is not
depressed, or is depressed
late
■When the accelerator pedal is
depressed excessively
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 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

Moving Vehicle Rear of
the Vehicle*
If a rear radar sensor detects a
vehicle approaching from the
right or left at the rear of the
vehicle and the system deter-
mines that the possibility of a
collision is high, this function
will perform brake control to
reduce the likelihood of an
impact with the approaching
vehicle.

●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
from the right or left at the rear 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.• 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.
