Driving
■The Parking Support Brake function
(rear-crossing vehicles) will operate
when
The function will operate when the PKSB
OFF indicator is not illuminated or flashing
(  P.72, 73) 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.
• Vehicles are approaching from the right or left at the rear of the vehicle at a travel-
ing speed of more than approximately 5
mph (8 km/h)
• The shift lever is in R.
• The Parking Support Brake determines that a stronger than normal brake opera-
tion is necessary to avoid a collision with
an approaching vehicle.
●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 an
approaching vehicle.
■The Parking Support Brake function
(rear-crossing vehicles) will stop operat-
ing 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.
• A vehicle is no longer approaching from the right or left at the rear of the vehicle.
●Brake 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.
• A vehicle is no longer approaching from
the right or left at the rear of the vehicle.
■Re-enabling the Parking Support Brake
function (rear-crossing vehicles)
 P.232
■Detection 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.223). 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.
■Conditions under which the Parking
Support Brake function (rear-crossing
vehicles) will not detect a vehicle
The Parking Support Brake function (rear-
crossing vehicles) is not designed to detect
the following types of vehicles and/or
objects:
●Vehicles approaching from directly
behind
●Vehicles backing up in a parking space
next to your vehicle
●Vehicles that the sensors cannot detect
due to obstructions
●Vehicles which suddenly accelerate or
decelerate near your vehicle
●Guardrails, walls, signs, parked vehicles
and similar stationary objects*
●Small motorcycles, bicycles, pedestrians,
WARNING
●If the area around a rear radar sensor
is subjected to an impact, the system
may not operate properly due to a
sensor malfunction. Have the vehicle
inspected by your Lexus dealer.
●Observe the rear radar sensor han-
dling precautions. ( P.208)

Driving
■Parking Support Brake function (rear
pedestrians) will operate when
The function will operate when the PKSB
OFF indicator is not illuminated or flashing
(  P.72, 73) 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
pedestrian.
■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
control.
• The brake pedal is depressed after the vehicle is stopped by brake control.
• The pedestrian is no longer detected behind your vehicle.
■Re-enabling the Parking Support Brake
function (rear pedestrians)
 P.232
■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.226). Therefore, even if the RCD
function detects a pedestrian and provides
an alert, the Parking Support Brake function
(rear pedestrians) may not start operating.
■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
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 ca nceled by depressing
the brake pedal.)
■In order to correctly use the Parking
Support Brake function (rear pedes-
trians)
Do not rely solely upon the system.
Depending on the road conditions, vehi-
cle conditions, and weather conditions,
etc., the system may not operate. The
detection capability of the rear camera is
limited. Always driv e while confirming
the safety of the surroundings of the vehi-
cle.
Also, if the PKSB OFF indicator is flash-
ing or the message indicating that the
system is unavailable is displayed over
the camera image, the system cannot be
used. However, even if the indicator is not
flashing or the message is not displayed,
do not rely solely upon the system and
make sure to always drive while directly
confirming the safety of your surround-
ings.
