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. (
■
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.

played on the multi-information display
A rear camera lens may be dirty or covered
with snow or ice. In such cases, if it is
removed from the rear camera lens, the sys-
tem should return to normal. (It may be nec-
essary to drive the vehicle for some time
before the system returns to normal.)

• 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.

Parking Support Brake function
(static objects)
Ultrasonic sensors are used to detect
static objects, such as a wall, in the
detection area when driving at a low
speed or backing up. (
■
Parking Support Brake function
(rear-crossing vehicles)
Rear radar sensors are used to detect
approaching vehicles in the detection
area behind the vehicle when backing
up. (
■
Parking Support Brake function
(rear pedestrians)
A rear camera sensor is used to detect
pedestrians in the detection area
behind the vehicle when backing up.

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.
