Driving
even after initialization, have the vehicle
inspected by your Lexus dealer.
■If a battery terminal has been discon-
nected and reconnected
The system needs to be initialized. To initial-
ize the system, drive the vehicle straight
ahead for 5 seconds or more at a speed of
approximately 22 mph (35 km/h) or more.
*: If equipped
This function will operate in situations
such as the following if an object is
detected in the traveling direction of
the vehicle.
Parking Support Brake func-
tion (static objects)*
If the sensors detect a static object,
such as a wall, in the traveling direc-
tion of the vehi cle and the system
determines that a collision may
occur due to the vehicle suddenly
moving forward due to an acciden-
tal accelerator pedal operation, the
vehicle moving the unintended
direction due to the wrong shift
position being selected, or while
parking or traveling at low speeds,
the system will operate to lessen
the impact with the detected static
object and reduce the resulting
damage.
Examples of function operation

2364-5. Using the driving support systems
■When traveling at a low speed and
the brake pedal is not depressed,
or is depressed late
■When the accelerator pedal is
depressed excessively
■When the vehicle moves in the
unintended direction due to the
wrong shift position being selected

WARNING
■Handling the suspension
Do not modify the suspension, as
changes to the height or inclination of the
vehicle may prevent the sensors from
detecting objects correctly or cause the
system to not operate or operate unnec-
essarily.
■If the Parking Support Brake function
(static objects) operates unnecessar-
ily, such as at a railroad crossing
In the event that the Parking Support
Brake function (static objects) operates
unnecessarily, such as at a railroad cross-
ing, brake control w ill be canceled after
approximately 2 seconds, allowing you
to proceed forward and leave the area,
brake control can also be canceled by
depressing the brake pedal. Depressing
the accelerator pedal after brake control
is canceled will allow you to proceed for-
ward and leave the area.
■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.
●When using a high pressure washer to
wash the vehicle, do not spray the sen-
sors directly, as doing so may cause a
sensor to malfunction.
●When using steam to clean the vehicle,
do not direct steam too close to the
sensors as doing so may cause a sen-
sor to malfunction.
■When to disable the Parking Support
Brake (static objects)
In the following situations, disable the
Parking Support Brake (static objects) as
the system may operate even though
there is no possibility of a collision.
●When inspecting the vehicle using a
chassis roller, chassis dynamo or free
roller
●When loading the vehicle onto a boat,
truck or other transport vessel
●If the suspension has been modified or
tires of a size other than specified are
installed
●If the front of the vehicle is raised or
lowered due to the carried load
●When equipment that may obstruct a
sensor is installed, such as a towing
eyelet, bumper protector (an addi-
tional trim strip, etc.), bicycle carrier, or
snow plow
●When using an automatic car wash

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.224) 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
■Situations in which the Parking Support
Brake function (stati c objects) may not
operate
When driving with the shift lever in N
■Intuitive parking assist buzzer
Regardless of whether the intuitive parking
assist function is enabled or not ( P.221), if
the Parking Support Brake function (static
objects) is enabled ( P.232), the front or
rear sensors detect an object and engine output restriction control or 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
• When driving on a narrow road
• When driving on a gravel road or in an area with tall grass
• When driving toward a banner, flag, low- hanging branch or boom barrier (such as
those used at railroad crossings, toll gates
and parking lots)
• When driving on a narrow path sur-
rounded by a structure, such as in a tun-
nel or on an iron bridge
• 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

2404-5. Using the driving support systems
*: If equipped
This function will operate in situations
such as the following if a vehicle is
detected in the traveling direction of
the vehicle.
■When reversing, a vehicle is
approaching and the brake pedal is
not depressed, or is depressed late
 P.216
■The Parking Support Brake function
(rear-crossing vehicles) will operate
when
The function will operate when the PKSB
OFF indicator is not illuminated or flashing
(  P.69, 70) and all of the following condi-
tions are met:
●Engine output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is 10 mph (15 km/h) or less.
• Vehicles which are ap proaching from the
right or left at the rear of the vehicle at a
traveling speed of more than approxi-
mately 5 mph (8 km/h)
• The shift lever is in R.
• The Parking Support Brake determines
that a stronger than normal brake opera-
tion is necessary to avoid a collision with
Parking Support Brake func-
tion (rear-crossing vehicles)*
If a rear radar sensor detects a vehi-
cle approaching from the right or
left at the rear of the vehicle and the
system determines that the possi-
bility of a collision is high, this func-
tion will perform brake control to
reduce the likelihood of an impact
with the approaching vehicle.
