■ Parking Support Brake function (rear
pedestrians) will operate when
The function will operate when the PKSB
OFF indicator is not illuminated or flashing
(

P.77, 78) and all of the following condi-
tions are met:
● Hybrid system output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is 9 mph (15 km/h) or
less.
• The shift position is in R.
• The rear camera sensor detects a pedes-
trian behind the vehicle while backing up
and the system determines that the possi-
bility of colliding with the detected
pedestrian is high.
● Brake control
• Hybrid system output restriction control
is operating.
• The Parking Support Brake determines
that an emergency brake operation is
necessary to avoid a collision with a
pedestrians.
■
The Parking Support Brake function
(rear pedestrians) will stop operating
when
The function will stop operating if any of the
following conditions are met:
●
Hybrid system output restriction control
• The Parking Support Brake is disabled.
• The collision becomes avoidable with
normal brake operation.
• The pedestrian is no longer detected
behind your vehicle.
●
Brake control
• The Parking Support Brake is disabled.
• Approximately 2 seconds have elapsed
since the vehicle was stopped by brake

■
Detection area of the Parking Support
Brake function (rear pedestrians)
The detection area of the Parking Support
Brake function (rear pedestrians) differs
from the detection area of the RCD func-
tion (

P.276). Therefore, even if the RCD
function detects a vehicle and provides an
alert, the Parking Support Brake function
(rear-crossing vehicles) may not start oper-
ating.
■ Situations in which the system may not
operate properly
● Some pedestrians, such as the following,
may not be detected by the Parking Sup-
port Brake function (rear pedestrians),
preventing the function from operating
properly:
• Pedestrians who are bending forward or
squatting
• Pedestrians who are lying down
• Pedestrians who are running
• Pedestrians who suddenly enter the
detection area
WARNING
■ If the Parking Support Brake function
(rear pedestrians) operates unneces-
sarily
Depress the brake pedal immediately
after the Parking Support Brake function
(rear pedestrians) operates. (Operation
of the function is canceled by depressing
the brake pedal.)
■ Correct use of the Parking Support
Brake function (rear pedestrians)
Do not overly rely on the Parking Sup-
port Brake function (rear pedestrians).
Depending on the road conditions, vehi-
cle conditions and weather, this function
may not operate correctly. As the detec-
tion performance of the rear camera is
limited, always drive safely, taking care to
observe your surroundings.
Additionally, if the PKSB OFF indictor is
flashing or a warning message is dis-
played on the center display indicating
that the Parking Support Brake function
(rear pedestrians) is unavailable, the
function cannot be used. Even if these
warnings are not output, the driver is
always responsible for paying attention
to the vehicle’s surroundings and driving
safely.
