Driving
When the Parking Support Brake is dis-
abled, the PKSB OFF indicator ( P. 9 2 ) illuminates.
To re-enable the system when it was
disabled, select on the multi-infor-
mation display, select 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 hybrid system output restric-
tion control or brake control oper-
ates, a buzzer will sound and a
message will be displayed on the
multi-information display and head-
up display (if equipped) to alert the
driver.
Depending on the situation, hybrid sys-
tem output restriction control will oper-
ate to either limit acceleration or restrict
output as much as possible.
 Hybrid system output restriction
control is operating (accelera-
tion restriction)
Acceleration greater than a certain
amount is restricted by the system.

Head-up display (if equipped): No
warning displayed
PKSB OFF indicator: Not illuminated
Buzzer: Does not sound
 Hybrid system output restriction

The system has determined that stron-
ger-than-normal brake operation is nec-
essary.

If the Parking Support Brake deter-
mines that a collision with a
detected object is possible, the
hybrid system output will be
restricted to restrain any increase in
the vehicle speed. (Hybrid system

■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 PKSB OFF indicator will illuminate. If the Parking Support Brake operates
unnecessarily, brake control can be can- celed by depressing the brake pedal or waiting for approximately 2 seconds for

it to automatically be canceled. Then,
the vehicle can be operated by depress- ing the accelerator pedal.
■Re-enabling the Parking Support Brake
To re-enable the Parking Support Brake when it is disabled due to operation of the Parking Support Brake, either
enable the system again ( P.266), or turn the power switch off and then back to ON. Additionally, if the object
becomes no longer in the traveling direction of the vehicle or if the traveling direction of the vehicle changes (such
as changing from moving forward to backing up, or from backing up to mov-ing forward), the system will be re-
enabled automatically.
■If “PKSB Unavailable” is displayed on the multi-information display and the PKSB OFF indicator is on
If the vehicle is stopped due to operation of the Parking Support Brake, the Park-ing Support Brake will be disabled and
the PKSB OFF indicator will illuminate.
●A sensor may be covered with water
drops, ice, snow, dirt, etc. Remove the water drops, ice, snow, dirt, etc., from the sensor to return the system to nor-
mal. Also, due to ice forming on a sensor at low temperatures, a warning message
may be displayed or the sensor may not be able to detect an object. Once the ice melts, the system will return to
normal.
●If this message is displayed, a sensor
on the front or rear bumper may be dirty. Clean the sensors and their sur-rounding area on the bumpers.
●If this message continues to be dis-played even after cleaning the sensor,
or is displayed even though the sen- sor is clean, have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■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 situations 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
Parking Support Brake function (static objects)*
If the sensors detect a static object, such as a wall, in the traveling
direction of the vehicle and the system determines that a colli sion
may occur due to the vehicle suddenly moving forward due to an
accidental 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 opera te to
lessen the impact with the detected static object and reduce th e
resulting damage.

■The Parking Support Brake func- tion (static object) will operate
when
The function will operate when the PKSB OFF indicator is not illuminated or
flashing ( P.91, 92) and all of the fol- lowing 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 brake operation is necessary to avoid
a collision.
●Brake control
• Hybrid system output restriction con- trol is operating.• 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.
■Re-enabling the Parking Support Brake function (static objects)
 P. 2 6 9
■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.258)
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 which the system may not be properly detected
 P. 2 5 6
■Toyota parking assist-sensor buzzer
Regardless of whether the Toyota park-
ing assist-sensor buzzer is enabled or not ( P.254), if the Parking Support Brake function (static objects) is enabled
( P.266), the front or rear sensors detect an 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.

■Detection area of the Parking Sup-
port Brake function (rear-crossing vehicles)
The detection area of the Parking Sup-
port Brake function (rear-crossing vehi- cles) differs from the detection area of the RCTA function ( P.261). Therefore,
even if the RCTA function detects a vehicle and provides an alert, the Park-ing Support Brake function (rear-cross-
ing vehicles) may not start operating.
