■Detection range of the sensorsApproximately 3.3 ft. (100 cm)
Approximately 4.9 ft. (150 cm)
Approximately 1.9 ft. (65 cm)
The diagram shows the detection range of
the sensors. Note that the sensors cannot
detect obstacles that are extremely close
to the vehicle.
The range of the sensors may change
depending on the shape of the object etc.
■Distance display
Sensors that detect an obstacle will illu-
minate continuously or blink. (As the
distance to the object becomes less
WARNING
■When using the intuitive parking
assist
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 use the sensor at speeds in
excess of 6 mph (10 km/h).
●The sensors’ detection areas and reac-
tion times are limited. When moving
forward or reversing, check the areas
surrounding the vehicle (especially the
sides of the vehicle) for safety, and
drive slowly, using the brake to control
the vehicle’s speed.
●Do not install accessories within the
sensors’ detection areas.
NOTICE
■When using intuitive parking assist
In the following situations, the system
may not function correctly due to a sen-
sor malfunction, etc. Have the vehicle
checked by your Lexus dealer.
●The intuitive parking assist operation
display flashes, and a buzzer sounds
when no obstacles are detected.
●If the area around a sensor collides
with something, or is subjected to
strong impact.
●If the bumper collides with something.
●If the display shows continuously with-
out beeping, except when the buzzer
mute switch has been turned on.
●If a display error occurs, first check the
sensor.
If the error occurs even if there is no
ice, snow or mud on the sensor, it is
likely that the sensor is malfunctioning.
■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.

■Buzzer operation and distance to
an obstacle
A buzzer sounds when the sensors are
operating. 
The buzzer sounds faster as the
vehicle approaches an obstacle.
When the vehicle comes within the
approximately 1.0 ft. (30 cm) of the
obstacle, the buzze r sounds contin-
uously.
 When 2 or more obstacles are
detected simultaneously, the buzzer
system responds to the nearest
obstacle. If one or both come within
the above distances, the beep will
repeat a long tone, followed by fast
beeps.
 Automatic buzzer mute function:
After a buzzer begins sounding, if
the distance between the vehicle
and the detected object does not
become shorter, the buzzer will be
muted automatically. (However, if
the distance between the vehicle
and object is 1.0 ft. (30 cm) or less,
this function will not operate.)

WARNING
■For safe use
Do not rely solely upon the system. Rely-
ing solely upon the sy stem may lead to an
unexpected accident.
●Driving safely is the sole responsibility
of the driver. Pay careful attention to
the surrounding conditions in order to
ensure safe driving. The Parking Sup-
port Brake function (f or static objects)
can provide support to lessen the
severity of collisions. However, it may
not operate depending on the situa-
tion.
●The Parking Support Brake function
(for static objects) is not a system
designed to completely stop the vehi-
cle. Furthermore, even if the Parking
Support Brake function (for static
objects) is able to stop the vehicle,
brake control is canceled after
approximately 2 seco nds, so depress
the brake pedal immediately.

to an impact, equipment may not oper-
ate properly due to a sensor malfunc-
tion. Have the vehicle inspected by
your Lexus dealer.
●When using a high-pressure washer to
wash the vehicle, do not spray water
directly on the sensors. The sensors
may not function properly if subjected
to an impact from strong water pres-
sure.
●When using steam to wash the vehicle,
do not direct steam too close to the
sensors. The sensor s may not function

■Operation starting conditions
When the PKSB OFF indicator is not illumi-
nated or flashing ( P.233, 370) and all of
the following conditions are met, the system
operates.
●Hybrid system output restriction control
• The Parking Support Brake function (for static objects) is on.
• The vehicle speed is 10 mph (15 km/h) or
less.
• There is an obstacle in the traveling direc- tion of the vehicle (6 to 13 ft. [2 to 4 m]
ahead).
• The system determined that a stronger- than-normal brake operation was neces-
sary to avoid a collision.
●Brake control
• Hybrid system output restriction control is being performed.
• The system determined that an emer-
gency brake operation was necessary to
avoid a collision.
■Operation ending conditions
In any of the following situations, the system
stops operating.
●Hybrid system output restriction control
• The Parking Support Brake function (for static objects) ha s been turned off
(stopped).
• The collision became avoidable with nor- mal brake operation.
• The obstacle is no longer in the traveling direction of the vehicle (6 to 13 ft. [2 to 4
m] ahead).
●Brake control
• The Parking Support Brake function (for
static objects) ha s been turned off
(stopped).
• Approximately 2 seconds elapsed after the vehicle was stopped by brake control.
• The brake pedal was depressed after the vehicle was stopped by brake control.
• The obstacle is no longer in the traveling
direction of the vehicle (6 to 13 ft. [2 to 4
m] ahead).
■Sensor detection range
The detection range of the Parking Support
Brake function (for static objects) differs
from the detection range of the clearance
sonar ( P.230).
Therefore, even if the clearance sonar
detects an obstacle and provides a warning,
the Parking Support Brake function (for
static objects) may not start operating.
■Obstacles not detect ed by the sensors
The following obstacles may not be
detected by the sensors.
●Objects such as people, cloth and snow,
that are difficult for sonic waves to reflect
off of. (In particular, people may also not
be detected depending on the type of
clothing they are wearing.)
●Objects not perpendicular with the
ground, objects not at a right angle to the
traveling direction of the vehicle, uneven
objects or waving objects
●Low objects
●Thin objects such as wires, fences, ropes
and signposts
●Objects that are extremely close to the
bumper
■Situations when the system may operate
even though there is no possibility of a
collision
In the following situations, the system may
operate even though there is no possibility
of a collision.
●Environmental influence
• The vehicle is driven on a narrow road

• The height of the vehicle has drastically
changed due to the carried load (the
nose tilts up or down)
• The direction of the sensor has deviated due to a collision or other impact
■When “Parking Support Brake Unavail-
able” is displayed on the multi-informa-
tion display and the PKSB OFF indicator
flashes
●Ice, snow, dirt, etc., may have adhered to
the sensor. If this occurs, remove the ice,
snow, dirt, etc., from the sensor to return
the system to normal.
Also, a warning message may be dis-
played at low temperatures due to ice
forming on the sensor, and the sensor
may not detect obstac les. Once the ice
melts, the system will return to normal.
●If this message is shown even after
removing dirt from the sensor, or shown
when the sensor was not dirty to begin
with, have the vehicle inspected by your
Lexus dealer.
●System initialization may not have been
performed after remova l and installation
of the 12-volt battery. Perform system ini-
tialization.
■When removing and installing the 12-
volt battery
The system needs to be initialized.
The system can be initialized by driving the
vehicle straight ahead for 5 seconds or
more at a speed of approximately 22 mph
(35 km/h) or higher.
■When “Parking Support Brake Mal-
function Visit Your Dealer” is displayed
on the multi-information display, the
PKSB OFF indicator flashes and the
buzzer sounds
The system may not be operating properly.
Have the vehicle inspected by your Lexus
dealer.
WARNING
■In order for the system to operate
properly
Make sure to observe the following pre-
cautions regarding the sensors
(  P.230). Failure to observe these pre-
cautions may cause the sensors not to
operate properly, and may result in an
unexpected accident.
●Do not perform work such as modifi-
cation, disassembly or painting
●Only perform replacements using
genuine parts
●Do not subject the area around the
sensors to any impacts
●Do not damage the sensors, and
always keep them clean
■Handling the suspension
Do not modify the suspension, as
changes to the height or incline of the
vehicle may prevent the sensors from
correctly detecting obstacles, may cause
the system not operate, or may cause the
system to operate unnecessarily.
NOTICE
■Preventing unnecessary operation
In the following situations, turn the Park-
ing Support Brake func tion (for static
objects) OFF. The system may operate
even though there is no possibility of a
collision.
●A chassis roller, chassis dynamo, free
roller or similar equipment is being
used for an inspection, etc.
●The vehicle is being loaded onto a ship,
truck or other transport vessel
●The suspension has been lowered or
tires that have a different size than the
genuine tires are equipped
●The height of the vehicle has drastically
changed due to the carried load (the
nose tilts up or down).

■The vehicle is stopped by system
operation
*: If the accelerator pedal is not depressed, “Press Brake Pedal” will be displayed.
■System operation
When the vehicle is stopped by system
operation, the Parking Support Brake func-
tion (for static objects) stops and the PKSB
OFF indicator illuminates.
■System recovery
When the Parking Support Brake function
(for static objects) is stopped by system
operation and you would like to resume
operation, either turn the Parking Support
Brake function (for static objects) ON again
(  P.233), or turn the power switch off and
then back on. Furthermore, when the vehi-
cle moves with an obstacle no longer in the
traveling direction of the vehicle, or when
the traveling direction of the vehicle
changes (such as when switching from
moving forward to backing up, and vice
versa), system operation automatically
resumes.
■Clearance sonar buzzer
Regardless of whether the clearance sonar
is on or off, if the Parking Support Brake
function (for static ob jects) is not stopped
(  P.233), when the front or rear sensors
detect an obstacle and brake control is per- formed, the clearance sonar buzzer also
sounds and a notification of the approxi-
mate distance to the obstacle is provided.
■In the unlikely event that the Parking
Support Brake function (for static
objects) mistakenly operates at a cross-
ing or elsewhere
Even in the unlikely event that the Parking
Support Brake function (for static objects)
mistakenly operates at a crossing or else-
where, brake control is canceled after
approximately 2 seconds, allowing you to
proceed forward and leave the area. Fur-
thermore, brake control is also canceled
when the brake pedal is depressed.
Depressing the accelerator pedal again
allows you to proceed forward and leave
the area.
