■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.

NOTICE
■Preventing sensor malfunctions
●If the area around a sensor is subjected 
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 
properly if subjected to steam.

■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

al_USA_M78287_en• The vehicle is tilted a large amount
• 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.
