tion 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
• 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
●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 signif icantly 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 othe r 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 in stalled 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 at tached) 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.
• If the temperature in the cabin is
extremely high or low, the Center Display
may not operate correctly.

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 vehicl e, it is necessary
to depress the brake pedal immedi-
ately as brake control will be canceled
after approximately 2 seconds.
NOTICE
■If “Parking Support Brake Unavail-
able” is displayed on the multi-infor-
mation display and the PKSB OFF
indicator is flashing
If this message is displayed immediately
after the power switch is changed to ON
mode, operate the vehicle carefully, pay-
ing attention to your surroundings. It may
be necessary to drive the vehicle for a
certain amount of time before the system
returns to normal. (If the system is not
return to normal afte r driving for a while,
clean the rear camera lens.)

●A sensor may be cove
red 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 wi ll 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 disp layed 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. ( P.223)
If this message continues to be displayed
even after initializati on, have the vehicle
inspected by your Lexus dealer.
