Parking Support Brake function (static objects)

*

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 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 detected static object and reduce the 
resulting damage.

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.

• There is a static object in the traveling 

direction of the vehicle and 6 to 13 ft. (2 

to 4 m) away.

• The Parking Support Brake determines 

that a stronger-than-normal brake opera-

tion is necessary to avoid a collision.

●

WARNING

●

If the area around a 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.

■

Handling the suspension

Do not modify the suspension, as 

changes to the height or inclination of the 

vehicle may prevent the sensors from 

detecting objects correctly or cause the 

system to not operate or operate unnec-

essarily.

■

If the Parking Support Brake function 

(static objects) operates unnecessar-

ily, such as at a railroad crossing

In the event that the Parking Support 

Brake function (static objects) operates 

unnecessarily, such as at a railroad cross-

ing, brake control will be canceled after 

approximately 2 seconds, allowing you 

to proceed forward and leave the area, 

brake control can also be canceled by 

depressing the brake pedal. Depressing 

the accelerator pedal after brake control 

is canceled will allow you to proceed for-

ward and leave the area.

■

Notes when washing the vehicle

Do not apply intensive bursts of water or 

steam to the sensor area.
Doing so may result in the sensor mal-

functioning.

●

When using a high pressure washer to 

wash the vehicle, do not spray the sen-

sors directly, as doing so may cause a 

sensor to malfunction.

●

When using steam to clean the vehicle, 

do not direct steam too close to the 

sensors as doing so may cause a sen-

sor to malfunction.

■

When to disable the Parking Support 

Brake

In the following situations, disable the 

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

Detection 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.269) 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.

Regardless of whether the intuitive parking 

assist system is enabled or not (

P.266), if 

the Parking Support Brake function (static 

objects) is enabled (

P.279), the front or 

rear sensors detect an object and brake 

control is performed, the intuitive parking 

assist buzzer will sound to notify the driver 

of the approximate distance to the object.

■

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.

denly, such as at the entrance or exit of a 

garage or underground parking lot

• When backing up in a dim environment 

such as during dusk or in an underground 

parking lot

●

Even though there are no pedestrians in 

the detection area, some objects, such as 

the following, may be detected, possibly 

causing the Parking Support Brake func-

tion (rear pedestrians) to operate.

• Three dimensional objects, such as a 

pole, traffic cone, fence, or parked vehi-

cle

• Moving objects, such as a car or motor-

cycle

NOTICE

■

Parking precaution

If the vehicle is parked for a long time, the 

vehicle height may change due to 

changes in the ambient temperature. 

When parking the vehicle, make sure 

that the area above and below the vehi-

cle is clear, so that the vehicle will not 

contact anything if its height changes.
Be careful when parking the vehicle in an 

area with a low ceiling or near low hang-

ing objects, as the vehicle height will 

increase when passengers exit the vehi-

cle and exit control of access mode 

operates.
