■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 1.2 ft. (35 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 sensors may not function
properly if subjected to steam.

■Operation starting conditions
When the PKSB OFF indicator is not illumi-
nated or flashing ( P.242, 378) and all of
the following conditions are met, the system
operates.
●Engine 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 a static ob ject in the traveling
direction 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
•Engine output restrict ion 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.
●Engine 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 static object is no longer in the travel-
ing direction of the vehicle (6 to 13 ft. [2 to 4 m] ahead).
●Brake control
• The Parking Support Brake function (for static objects) has 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 static object is no longer in the travel- ing 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.239).
Therefore, even if the clearance sonar
detects a static object and provides a warn-
ing, the Parking Support Brake function (for
static objects) may not start operating.
■Static objects not detected by the sen-
sors
The following static objects 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

Driving
• The vehicle is driven on a gravel road or
in an area with tall grass
• Ice, snow, dirt, etc., has adhered to the sensor (if removed, the system returns to
normal)
• Heavy rain or water strikes the vehicle
• In severe weather such as fog, snow or a sand storm
●Influence from other sonic waves
• An ultrasonic wave source is nearby, such
as the horn or clearance sonar of another
vehicle, a vehicle detector, a motorcycle
engine or the air brake of a large vehicle
• Electronic components (such as a backlit license plate (especially fluorescent
types), fog lights, a fender pole or a wire-
less antenna) are installed near the sen-
sors
●Changes in the vehicle
• 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 static objects. 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 battery. Perform system initializa-
tion.
■When removing and installing the bat-
tery
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.239). 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

2484-5. Using the driving support systems
LEXUS NX300 Owners Manual_USA_M78389_en
When the engine output restriction
control or brake control operates, the
buzzer sounds and a message is dis-
played on the multi-information dis- play, head-up display and
navigation/multimedia system screen
to alert the driver.
Depending on the situation, output restric-
tion control operates to either limit accel-
eration or restrict output as much as
possible.
■Engine output restriction control is
operating (acceleration limitation
control)
■Engine output restriction control is
operating (control to restrict out-
put as much as possible)
WARNING
●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 static objects, may
cause the system not operate, or may
cause the system to operate unnecessar-
ily.
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).
●A towing hook is installed
●When using an automatic car wash

Driving
■Brake control is operating
■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.242), or turn the engine switch off and
then back on. Furthermore, when the vehi-
cle moves with a static object 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.242), when the front or rear sensors
detect a static object and brake control is
performed, the clearance sonar buzzer also
sounds and a notification of the approxi-
mate distance to the static object is pro-
vided.
■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.
