den by an object, such as a cart or 

umbrella

• Pedestrians which are obscured by dark-

ness, such as at night

●

In some situations, such as the following, 

pedestrians may not be detected by the 

rear camera detection function, prevent-

ing the function from operating properly:

• When backing up in inclement weather 

(rain, snow, fog, etc.)

• When the rear camera is obscured (dirt, 

snow, ice, etc. are attached) or scratched

• When a very bright light, such as the sun, 

or the headlights of another vehicle, 

shines directly into the rear camera

• When backing up in a place where the 

surrounding brightness changes sud-

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 rear camera detection func-

tion 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

• Objects moving toward your vehicle 

when backing up, such as flags or pud-

dles (or airborne matter, such as smoke, 

steam, rain, or snow)

• Cobblestone or gravel roads, tram rails, 

road repairs, white lines, pedestrian 

crossings or fallen leaves on the road

• Metal covers (gratings), such as those 

used for drainage ditches

• Objects reflected in a puddle or on a wet 

road surface

• The roadside or bumps on the road 

• Shadows  on  the  road

●

In some situations, such as the following, 

the rear camera detection function may 

operate even though there are no pedes-

trians in the detection area.

• When backing up toward the roadside or 

a bump on the road

• If the vehicle is significantly tilted, such as 

when carrying a heavy load

• When backing up toward an 

incline/decline

• If the suspension has been modified or 

tires of a size other than specified are 

installed

• If the rear of the vehicle is raised or low-

ered due to the carried load

• If an electronic component, such as a 

backlit license plate is installed near the 

rear camera

• If a bumper protector, such as an addi-

tional trim strip, is installed to the rear 

bumper

• If the orientation of the rear camera has 

been changed due to a collision or other 

impact, or removal and installation

• If a towing eyelet is installed to the rear of 

the vehicle

• When water is flowing over the rear cam-

era lens

• When the rear camera is obscured (dirt, 

snow, ice, etc. are attached) or scratched

• If there is a flashing light in the detection 

area, such as the emergency flashers of 

another vehicle

●

Situations in which the rear camera 

detection function may be difficult to 

notice

• The buzzer may be difficult to hear if the 

surrounding area is noisy, the volume of 

the audio system volume is high, the air 

conditioning system is being used, etc.

PKSB (Parking Support 
Brake)

*

The 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 deter-
mines that the possibility of a colli-
sion with a detected object or 
pedestrian is high, a warning oper-
ates to urge the driver to take eva-
sive action. If the system 
determines that the possibility of a 
collision with a detected object or 
pedestrian is extremely high, the 
brakes are automatically applied to 
help avoid the collision or help 
reduce the impact of the collision.

WARNING

■

Limitations of the Parking Support 

Brake system

Do not overly rely on the system, as 

doing so may lead to an accident.

●

The driver is solely responsible for safe 

driving. Always drive carefully, taking 

care to observe your surroundings. 

The Parking Support Brake system is 

designed to provide support to lessen 

the severity of collisions. However, it 

may not operate in some situations.

●

The 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 immedi-

ately as brake control will be canceled 

after approximately 2 seconds.

●

A sensor may be covered with ice, snow, 

dirt, etc. Remove the ice, snow, dirt, etc., 

from the sensor to return the system to 

normal.

Also, due to ice forming on a sensor at 

low temperatures, a warning message 

may be displayed or the sensor may not 

be able to detect an object. Once the ice 

melts, the system will return to normal.

●

If this message is displayed only when the 

shift lever is in R, the rear camera lens 

may be dirty. Clean the camera lens. If 

this message is displayed when the shift 

lever is in any position other than R, a sen-

sor on the front or rear bumper may be 

dirty. Clean the sensors and their sur-

rounding area on the bumpers.

●

If this message continues to be displayed 

even after cleaning the sensor, or is dis-

played even though the sensor is clean, 

have the vehicle inspected by your Lexus 

dealer.

●

Initialization may not have been per-

formed after a 12-volt battery terminal 

was disconnected and reconnected. Ini-

tialize the system. (

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.208) 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.

■

Objects that the Parking Support Brake 

function (static objects) may not detect

The sensors may not be able to detect cer-

tain objects, such as the following:

●

Pedestrian

●

Cotton cloth, snow, and other materials 

that are poor reflectors of ultrasonic 

waves

●

Objects which are not perpendicular to 

the ground, are not perpendicular to the 

traveling direction of the vehicle, are 

uneven or are waving

●

Low objects

●

Thin objects such as wires, fences, ropes 

and signposts

●

Objects that are extremely close to the 

bumper

■

Intuitive parking assist buzzer

Regardless of whether the intuitive parking 

assist system is enabled or not (

P.206), if 

the Parking Support Brake function (static 

objects) is enabled (

P.219), 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.

Situations in which the Parking Support 

Brake function (static objects) may 

operate even if there is no possibility of a 

collision

In some situations, such as the following, the 

Parking Support Brake function (static 

objects) may operate even though there is 

no possibility of a collision.

●

Vehicle surroundings

• When driving on a narrow road

• When driving on a gravel road or in an 

area with tall grass

• When driving toward a banner, flag, low-

hanging branch or boom barrier (such as 

those used at railroad crossings, toll gates 

and parking lots)

• When driving on a narrow path sur-

rounded by a structure, such as in a tun-

nel or on an iron bridge

• When parallel parking

• When there is a rut or hole in the surface 

of the road

• When driving on a metal cover (grating), 

such as those used for drainage ditches

• When driving on a steep slope

• If a sensor is hit by a large amount of 

water, such as when driving on a flooded 

road

●

Weather

• If a sensor is covered with ice, snow, dirt,

etc. (when cleared, the system will return 

to normal)

• If heavy rain or water strikes a sensor

• When driving in inclement weather such 

as fog, snow or a sandstorm

●

Other ultrasonic wave sources

• When vehicle horns, vehicle detectors, 

motorcycle engines, air brakes of large 

vehicles, the clearance sonar of other 

vehicles or other devices which produce 

ultrasonic waves are near the vehicle

• If a sticker or an electronic component, 

such as a backlit license plate (especially 

fluorescent type), fog lights, fender pole 

or wireless antenna is installed near a 

sensor

●

Changes in the vehicle posture

• If the vehicle is significantly tilted

• If the front of the vehicle is raised or low-

ered due to the carried load

• If the orientation of a sensor has been 

changed due to a collision or other 

impact

■

Situations in which the Parking Support 

Brake function (static objects) may not 

operate properly

In some situations, such as the following, this 

function may not operate properly.

●

Weather

• When a sensor or the area around a sen-

sor is extremely hot or cold

• When strong winds are blowing

• If a sensor is covered with ice, snow, dirt, 

etc. (when cleared, the system will return 

to normal)

• If heavy rain or water strikes a sensor

• When driving in inclement weather such 

as fog, snow or a sandstorm

●

Vehicle surroundings

• When an object that cannot be detected 

is between the vehicle and a detected 

object

• If an object such as a vehicle, motorcycle, 

bicycle or pedestrian cuts in front of the 

vehicle or runs out from the side of the 

vehicle

●

Other ultrasonic waves sources

• When vehicle horns, vehicle detectors, 

motorcycle engines, air brakes of large 

vehicles, the clearance sonar of other 

vehicles or other devices which produce 

ultrasonic waves are near the vehicle

• If a sticker or an electronic component, 

such as a backlit license plate (especially 

fluorescent type), fog lights, fender pole 

or wireless antenna is installed near a 

sensor

●

Changes in the vehicle posture

• If the vehicle is significantly tilted

• If the front of the vehicle is raised or low-

ered due to the carried load

• If the orientation of a sensor has been 

changed due to a collision or other 

impact

Driving

*

: If  equipped

This function will operate in situations such as the following if a vehicle is detected 
in the traveling direction of the vehicle.

Parking Support Brake function (rear-crossing vehicles)

*

If a rear radar sensor detects a vehicle approaching from the right or left at the 
rear of the vehicle and the system determines that the possibility of a collision 
is high, this function will perform brake control to reduce the likelihood of an 
impact with the approaching vehicle.

WARNING

■

To ensure the Parking Support Brake 

(rear-crossing vehicles) can operate 

properly

Observe the following precautions 

regarding the rear radar sensors 

(

P.198). Failure to do so may cause a 

sensor to not operate properly, and may 

cause an accident.

●

Do not modify, disassemble or paint 

the sensors.

●

Do not replace a rear radar sensor 

with a part other than a genuine part.

●

Do not damage the rear radar sensors, 

and always keep the radar sensors and 

their surrounding area on the bumper 

clean.
