WARNING

■

Cautions regarding the use of the sys-

tem

There is a limit to the degree of recogni-

tion accuracy and control performance

that this system can provide, do not

overly rely on this system. The driver is

always responsible for paying attention

to the vehicle’ surroundings and driving

safely.

■

To ensure the system can operate

properly

Observe the following precautions.

Failing to do so may result in the vehicle

being unable to be driven safely and pos-

sibly cause an accident.

●

Do not damage the sensors, and

always keep them clean.

●

Do not attach a sticker or install an

electronic component, such as a back-

lit license plate (especially fluorescent

type), fog lights, fender pole or wire-

less antenna near a radar sensor.

●

Do not subject the surrounding area of

the sensor to a strong impact. If sub-

jected to an impact, have the vehicle

inspected by your Lexas dealer. If the

front or rear bumper needs to be

removed/installed or replaced, con-

tact your Lexas dealer.

●

Do not modify, disassemble or paint

the sensors.

●

Do not attach a license plate cover.

●

Keep your tires properly inflated.

■

The system can be operated when

●

The power switch is in ON mode.

●

Intuitive parking assist function is on.

●

The vehicle speed is less than about 6

mph (10 km/h).

●

A shift position other than P is selected.

■

Setting the buzzer volume

The buzzer volume can be adjusted on the

multi-information display. (



P.283)

■

If “Clean Parking Assist Sensor” is dis-

played on the multi-information display

A sensor may be covered with water drops,

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

ice, snow, dirt, etc., from the sensor to return

the system to normal.
If a sensor is dirty, the position of the dirty

sensor will be shown on the display.
Due to ice forming on a sensor at low tem-

peratures, a warning message may be dis-

played or the sensor may not be able to

detect an object. Once the ice melts, the

system will return to normal.

■

If “Parking Assist Unavailable” is dis-

played on the multi-information display

Water may be continuously flowing over the

sensor surface, such as in a heavy rain.

When the system determines that it is nor-

mal, the system will return to normal.

■

Sensor detection information

●

The following situations may occur

during use.

• The sensors may be able to only detect

objects near the front and rear bumpers.

• Depending on the shape of the object

and other factors, the detection distance

may shorten, or detection may be impos-

sible.

• There will be a short delay between

object detection and display. Even at low

speeds, there is a possibility that the

object will come within the sensor’s

detection areas before the display is

shown and the warning beep sounds.

• It might be difficult to hear the buzzer due

to the volume of the audio system or air

flow noise of the air conditioning system.

• It may be difficult to hear the buzzer if

buzzers for other systems are sounding.

■

Objects which the system may not be

properly detected

The shape of the object may prevent the

sensor from detecting it. Pay particular

attention to the following objects:

●

Wires, fences, ropes, etc.

●

Cotton, snow and other materials that

absorb sound waves

●

Sharply-angled objects

●

Low objects

●

Tall objects with upper sections project-

ing outwards in the direction of your vehi-

cle

People may not be detected if they are

wearing certain types of clothing.

■

Situations in which the system may not

operate properly

Certain vehicle conditions and the sur-

rounding environment may affect the ability

of a sensor to correctly detect objects. Par-

WARNING

■

When to disable the function

In the following situations, disable the

function as it may operate even though

there is no possibility of a collision.

●

Failing to observe the warnings above.

●

A non-genuine Lexus suspension

(lowered suspension, etc.) is installed.

■

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.

Object
Calculated vehicle route

When the vehicle is moving, the side sensors or side cameras can detect objects.
While the vehicle is moving, if a detected object can no longer be detected by the
side sensors or side cameras, the location of the object relative to the vehicle is
estimated. If the object is determined to be in the estimated path of the vehicle, the
object warning function will operate.

Object detected by side sensors or side cameras

The vehicle is stopped and objects along the sides of the vehicle are not
detected.

Objects are detected as the vehicle is moving.

Even though the objects are outside of the detection area of the side sensors or
side cameras, a warning is displayed and a buzzer sounds.

• Pedestrians who are bending forward or

squatting

• Pedestrians who are lying down

• Pedestrians who are running

• Pedestrians who suddenly enter the

detection area

• People riding a bicycle, skateboard, or

other light vehicle

• Pedestrians wearing oversized clothing

such as a rain coat, long skirt, etc., making

their silhouette obscure

• Pedestrians whose body is partially hid-

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

• When the camera position and direction

are deviated

• When a towing hook is attached

• When water droplets are flowing on the

camera lens

• When the vehicle height is extremely

changed (nose up, nose down)

• When tire chains or an emergency tire

puncture repair kit is used

■

Situations in which the system may

operate unexpectedly

●

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

• 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

• When backing up toward an

incline/decline

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

ered due to the carried load

• If the orientation of the rear camera has

been changed

• 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

• When a tire chains or an emergency tire

puncture repair kit is used

●

Situations in which the rear camera

detection function may be difficult to

notice

• If 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.

• If the temperature in the cabin is

extremely high or low, the audio system

screen may not operate correctly.

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 a collision with a
detected object or pedestrian is
high, a warning operates to urge
the driver to take evasive action. If
the system determines that the pos-
sibility 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 colli-
sion.

Cautions regarding the use of the sys-

tem

Do not overly rely on the system, as

doing so may lead to an accident. Always

drive while checking the safety of the sur-

roundings of the vehicle.
Depending on the vehicle and road con-

ditions, weather, etc., the system may not

operate.
The detection capabilities of sensors,

radars and camera are limited. Always

drive while checking the safety of the sur-

roundings of the vehicle.

●

Do not attempt to test the operation of

this system by driving the vehicle

toward another vehicle, a person or

detected object, as it may not operate

properly, possibly leading to an acci-

dent.

●

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.

●

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.
