sarily, brake control can be canceled by
depressing the brake pedal or waiting for
approximately 2 seconds for it to automati-
cally be canceled. Then, the vehicle can be
operated by depressing the accelerator
pedal.
■Re-enabling the Park ing Support Brake
To re-enable the Parking Support Brake
when it has been disabled due to system
operation, perform any of the following
operations. At this time, the PKSB OFF indi-
cator will turn off. ( P.73)
●Turn the PKSB system on ( P.229)
●Turn the power switch off, and then back
to ON mode
●Shift the shift lever to P

■If “Parking Support Brake Unavailable”
is displayed on th e multi-information
display and the PKSB OFF indicator is
flashing
●If this message is di splayed 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.
●Initialization may not have been per-
formed after a 12-volt battery terminal
was disconnected and reconnected. Ini-
tialize the system. ( P.233)
If this message continues to be displayed
even after initializati on, have the vehicle
inspected by your Lexus dealer.
■If “Parking Support Brake Unavailable”
and “Parking Assist Unavailable Clean
Parking Assist Sensor” are displayed on
the multi-information display and the
PKSB OFF indicator is flashing
●A sensor may be cove red with ice, snow,
dirt, etc. In this case, remove the ice,
snow, dirt, etc., from the sensor to return
the system to normal. If this message is
shown even after removing dirt from the

• The static object is no longer 6 to 13 ft. (2 to 4 m) away from the vehicle or in the
traveling direction of the vehicle.
●Brake control
• The Parking Support Brake is disabled.
• Approximately 2 seconds have elapsed since the vehicle was stopped by brake
control.
• The brake pedal is depressed after the vehicle is stopped by brake control.
• The static object is no longer 6 to 13 ft. (2 to 4 m) away from the vehicle or in the
traveling direction of the vehicle.
■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.218) Therefore, even if the intui-
tive parking assist de tects 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 obje cts) 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
●Sharply-angled objects
●Tall objects with upper sections project-
ing outwards in the direction of your vehi-
cle

■Intuitive parking assist buzzer
Regardless of whether the intuitive parking
assist system is enabled or not ( P.216), if
the Parking Support Brake function (static
objects) is enabled ( P.229), 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

rounded by a structure, such as in a tun-
nel or on an iron bridge

2384-5. Using the driving support systems
• 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 incl ement weather such
as fog, snow or a sandstorm
• When strong winds are blowing
●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 el ectronic 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 (stati c 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)

■In order to correctly use the Parking
Support Brake function (rear pedes-
trians)
Do not rely solely upon the system.
Depending on the road conditions, vehi-
cle conditions, and weather conditions,
etc., the system may not operate. The
detection capability of the rear camera is
limited. Always driv e while confirming
the safety of the surroundings of the vehi-
cle.
Also, if the PKSB OFF indicator is flash-
ing or the message indicating that the
system is unavailable is displayed over
the camera image, the system cannot be
used. However, even if the indicator is not
flashing or the message is not displayed,
do not rely solely upon the system and
make sure to always drive while directly
confirming the safety of your surround-
ings.
