Buzzer and screen notifications when traveling at a low speed and a
pedestrian is detected at the rear

Purpose of the RCD (Rear Camera Detection)

When the vehicle is backing up, the rear camera detection function can detect
pedestrians in the detection area behind the vehicle. If a pedestrian is detected, a
buzzer will sound and an icon will be displayed on the center display to inform the
driver of the pedestrian.

WARNING

■

Cautions regarding the use of the system

The recognition and control capabilities for this system are limited.
The driver should always drive safely by always being responsible without over relying on
the system and have a understanding of the surrounding situations.

■

To ensure the system can operate properly

Observe the following, otherwise there is the danger that could lead to an accident.

●

Always clean the camera with damaging it.

●

Do not install market electronic parts (such as Illuminated license plate, fog lamps,
etc.) in the camera vicinity.

●

Do not subject the camera vicinity to strong impacts. If the vicinity is subjected to a
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.

●

The contents mentioned above are not observed.

●

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.)

INFORMATION

■

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 PKSB (Parking Support Brake) system can be changed between ON (ena-
bled) and OFF (disabled) on the center display.

Select

Select [Driving assist].

Select [Parking support brake] to change ON (enable)/OFF (disabled).

When the PKSB (Parking Support Brake) is disabled, the driving assist infomation
indicator illuminates.
When turned OFF (disabled), the PKSB (Parking Support Brake) will be disabled
and will not be enabled until the setting is changed to ON again in center display.
(The function will not be reenabled by operating the power switch.)

PKSB (Parking Support Brake) function displays and buzzers

When the hybrid system output restriction control or brake control operates,
a buzzer sounds and a message is displayed on the multi-information display,

Depending on the situation, output restriction control operates to either limit
acceleration or restrict output as much as possible.

Static Objects Front and Rear of the vehicle

If the sensors detect a static object, such as a wall, in the travelling 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 operation, the
vehicle moving the unintended direction due to the wrong shift position, or while
parking or traveling at low speeds, the system will operate to lessen the impact with
the detected static object and reduce the resulting damage.
