QIf a 12-volt battery terminal has been
disconnected and reconnected
The system needs to be initialized. To initial-
ize the system, drive the vehicle straight
ahead for 5 seconds or more at a speed of
approximately 22 mph (35 km/h) or more.
Additionally, for vehicles with the Parking
Support Brake function, turn the steering
wheel fully to the left and right with the vehi-
cle stopped.

2464-5. Using the driving support systems
*: If equipped
This function will operate in situations such as the following if an object is detected
in the traveling direction of the vehicle.
QWhen 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 collision may occur due to the
vehicle suddenly moving forward due to an accidental accelerator pedal oper-
ation, the vehicle moving the unintended direction due to the wrong shift posi-
tion being selected, or while parking or traveling at low speeds, the system will
operate to lessen the impact with the de tected static object and reduce the
resulting damage.

( P.73, 74) and all of the following condi-
tions are met:
OHybrid system output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is approximately 9
mph (15 km/h) or less.
• There is a static ob ject in the traveling
direction of the vehicle and approxi-
mately 6 to 13 ft. (2 to 4 m) away.
• The Parking Support Brake determines that a stronger-than-normal brake oper-
ation is necessary to avoid a collision.
OBrake control
• Hybrid system output restriction control is operating.
• The Parking Support Brake determines
that an immediate brake operation is
necessary to avoid a collision.
QThe Parking Support Brake function
(static objects) will stop operating when
The function will stop operating if any of the
following conditions are met:
OHybrid system output restriction control
• The Parking Support Brake is disabled.
• The system determines that the collision has become avoidable with normal brake
operation.
• The static object is no longer approxi- mately 6 to 13 ft. (2 to 4 m) away from the
vehicle or in the trav eling direction of the
vehicle.
OBrake control
• The Parking Support Brake is disabled.
• 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 control.
• The static object is no longer approxi- mately 6 to 13 ft. (2 to 4 m) away from the
vehicle or in the trav eling direction of the
vehicle.
QDetection range of the Parking Support
Brake function (static objects)
The detection range of the Parking Support
Brake function (static objects) differs from
the detection range of the intuitive parking
assist. ( P.227) Therefore, even if the intu-
itive parking assist detects an object and
provides a warning, the Parking Support
Brake function (static objects) may not start operating.
QSituations in which
the Parking Support
Brake function (static objects) may not

• The vehicle speed is approximately 9
mph (15 km/h) or less.
• Vehicles are approaching from the right or left at the rear of the vehicle at a travel-
ing speed of approximately 5 mph (8
Parking Support Brake function (rear-crossing vehicles)*
If a rear radar sensor detects a vehicle approaching from the right or left at the
rear of the vehicle and the system determines 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.

tion is necessary to avoid a collision with
an approaching vehicle.

• The Parking Support Brake determines that an emergency brake operation is
necessary to avoid a collision with an
approaching vehicle.
QThe Parking Support Brake function

ating when
The function will stop operating if any of the
following conditions are met:
OHybrid system output restriction control
• The Parking Support Brake is disabled.
• 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.
OBrake control
• The Parking Support Brake is disabled.
• Approximately 2 seconds have elapsed

• The brake pedal is depressed after the
vehicle is stopped by brake control.
• A vehicle is no longer approaching from the right or left at the rear of the vehicle.
QDetection area of the Parking Support
Brake function (rear-crossing vehicles)
The detection area of the Parking Support
Brake function (rear-crossing vehicles) dif-
fers from the detection area of the RCTA
function ( P.232). Therefore, even if the
RCTA function detects a vehicle and pro-
vides an alert, the Parking Support Brake
function (rear-crossing vehicles) may not
start operating.

Parking Support Brake function (rear pedestrians)*
If the rear camera sensor detects a pedestrian behind the vehicle while back-
ing up and the system determines that the possibility of colliding with the
detected pedestrian is high , a buzzer will sound. If the system determines that
the possibility of colliding with the dete cted pedestrian is extremely high, the
brakes will be applied automatically to help reduce the impact of the collision.

tion ( P.237). Therefore, even if the RCD
function detects a pedestrian and provides
an alert, the Parking Support Brake func-
tion (rear pedestrians) may not start operat-
ing.
