strong impact, have the vehicle inspected by your Lexus dealer.
●
Do not disassemble, remodel or paint the camera.
●
Do not attach accessories or stickers to the camera.
●
Do not install market protection parts (bumper trim, etc.) to the rear bumper.
●
Maintain suitable tire air pressure.
●
Make sure the back door is completely closed.
■
RCD function is turned off
In the following situations the system turns off. The RCD function may not operate
properly and thus there is the danger that an accident may occur.

Brake operation when an object is detected while approaching at low
speed
Purpose of the PKSB (Parking Support Brake) system
The PKSB (Parking Support Brake) system consists of the following functions that
operate when driving at a low speed or backing up, such as when parking. When
the system determines that the probability of a collision with a detected object is
high, a warning operates to urge the driver to take evasive action.
■
Parking assist function
The system can detect the following as detectable objects. (Detectable objects
differ depending on the function.)
●
Static Objects Front and Rear of the vehicle
●
Moving Vehicles Rear of the Vehicle
●
Pedestrians Rear of the Vehicle
●
Static Objects Around the vehicle (vehicles with Advanced Park)
PKSB (Parking Support Brake) system
WARNING
■
Cautions regarding the use of the system
Do not overly rely on the system, as doing so may lead to an accident. Always drive while
checking the safety of the surroundings of the vehicle.
Depending on the vehicle and road conditions, weather, etc., the system may not operate.
The detection capabilities of sensors and radars are limited. Always drive while checking
the safety of the surroundings of the vehicle.
●
The driver is solely responsible for safe driving. Always drive carefully, taking care to
observe your surroundings. The PKSB (Parking Support Brake) system is designed
to provide support to lessen the severity of collisions. However, it may not operate in
some situations.
●
The PKSB (Parking Support Brake) system is not designed to stop the vehicle com-
pletely. Additionally, even if the system has stopped the vehicle, it is necessary to
depress the brake pedal immediately as brake control will be canceled after approxi-
mately 2 seconds.
●
It is extremely dangerous to check the system operations by intentionally driving the
vehicle into the direction of a wall, etc. Never attempt such actions.

WARNING
■
When to disable the PKSB (Parking Support Brake) system
In the following situations, disable the PKSB (Parking Support Brake) as the system may
operate even though there is no possibility of a collision.
●
When inspecting the vehicle using a chassis roller, chassis dynamo or free roller
●
When loading the vehicle onto a boat, truck or other transport vessel
●
If the suspension has been modified or tires of a size other than specified are installed
●
If the front of the vehicle is raised or lowered due to the carried load
●
When equipment that may obstruct a sensor is installed, such as a towing eyelet,
bumper protector (an additional trim strip, etc.), bicycle carrier, or snow plow
●
When using automatic car washing devices
●
If the vehicle cannot be driven in a stable manner, such as when the vehicle has been in
an accident or is malfunctioning
●
When the vehicle is driven in a sporty manner or off-road
●
When the tires are not properly inflated
●
When the tires are very worn
●
When a tire chains, compact spare tire or an emergency tire puncture repair kit is
used
■
Precautions for the suspension
Do not modify the suspension of the vehicle. If the height or tilt of the vehicle is changed,
the sensors may not be able to detect detectable objects and the system may not operate
correctly, possibly leading to an accident.
■
System overview
If the PKSB (Parking Support Brake) determines that a collision with a detected
object or pedestrian is possible, the hybrid system output will be restricted to re-
strain any increase in the vehicle speed. (Hybrid 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 PKSB (Parking Support Brake) system has operated
If the vehicle is stopped due to operation of the PKSB (Parking Support Brake), the PKSB
(Parking Support Brake) will be disabled and the driving assist infomation indicator will
illuminate.
If the PKSB (Parking Support Brake) system operates unnecessarily, brake control can
be canceled by depressing the brake pedal or waiting approximately 2 seconds for
it to automatically be canceled. Then, the vehicle can be operated by depressing the
accelerator pedal.

The function will operate when the driving assist infomation indicator is not illuminated or
flashing and all of the following conditions are met:
●
Hybrid system output restriction control
•
PKSB (Parking Support Brake) system is enabled.
•
The vehicle speed is approximately 9 mph (15 km/h) or less.
•
There is a static object in the traveling direction of the vehicle (approximately 6 to
13 ft. [2 to 4 m] ahead).
•
The Parking Support Brake determines that a stronger-than-normal brake opera-
tion is necessary to avoid a collision.
●
Brake control
•
Hybrid system output restriction control
•
The Parking Support Brake determines that an immediate brake operation 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:
●
Hybrid system output restriction control
•
PKSB (Parking Support Brake) system is disabled.
•
The system determines that the collision has become avoidable with normal brake
operation.
•
The static object is no longer in the traveling direction of the vehicle or approxi-
mately 6 to 13 ft. (2 to 4 m) away from the vehicle.
●
Brake control
•
PKSB (Parking Support Brake) system 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 in the traveling direction of the vehicle or approxi-
mately 6 to 13 ft. (2 to 4 m) away from the vehicle.
■
Detection range
The detection range of the system differs from the detection range of the intuitive parking
assist.
6-2. Using the safe driving support functions
428
Therefore, even if the intuitive parking assist detects a static object and provides a
warning, the PKSB (Parking Support Brake) system may not start operating.
■
Intuitive parking assist sensor buzzer
Regardless of whether the intuitive parking assist sensor buzzer is enabled or not, if the
PKSB (Parking Support Brake) system is enabled, the front or rear sensors detect an
object and brake control is performed, the intuitive parking assist buzzer buzzer will
sound to notify the driver of the approximate distance to the object.
