( → P.295)PKSB (Parking Support
Brake) *
The Parking Support Brake system
consists of the following functions
that operate when driving at a low
speed or backing up, such as when
parking. When the system deter-
mines that a collision with a
detected object or pedestrian is
high, a warning operates to urge
the driver to take evasive action. If
the system determines that the pos-
sibility of a collision with a detected
object or pedestrian is extremely
high, the brakes are automatically
applied to help avoid the collision or
help reduce the impact of the colli-
sion.
PKSB (Parking Support Brake)
system WARNING■
Limitations of the Parking Support
Brake system
Do not overly rely on the system, as
doing so may lead to an accident. ●
The driver is solely responsible for safe
driving. Always drive carefully, taking
care to observe your surroundings.
The Parking Support Brake system is
designed to provide support to lessen
the severity of collisions. However, it
may not operate in some situations. ●
The Parking Support Brake system is
not designed to stop the vehicle com-
pletely. Additionally, even if the system
has stopped the vehicl e, it is necessary
to depress the brake pedal immedi-
ately as brake control will be canceled
after approximately 2 seconds.
NOTICE■
If “Parking Support Brake Unavail-
able” is displayed on the multi-infor-
mation display and the PKSB OFF
indicator is flashing
If this message is displayed immediately
after the power switch is changed to ON
mode, operate the vehicle carefully, pay-
ing attention to your surroundings. It may
be necessary to drive the vehicle for a
certain amount of time before the system
returns to normal. (If the system is not
return to normal afte r driving for a while,
clean the rear camera lens.)

Driving The Parking Support Brake can be
enabled/disabled on the multi-informa-
tion display. All of the Parking Support
Brake functions (static objects,
rear-crossing vehicles, and rear pedes-
trians) are enabled/disabled simultane-
ously.
Use the meter control switches to
enable/disable the parking support
brake. ( → P.87)
1 Press or to select .
2 Press or to select
and then press .When the Parking Support Brake is dis-
abled, the PKSB OFF indicator ( → P.72)
illuminates on the multi-information dis-
play.
To re-enable the system when it was dis-
abled, select on the multi-information
display, select and then On. If dis-
abled using this method, the system will not
be re-enabled by turning the power switch
off and then to ON mode.
If the hybrid system output restriction con-
trol or brake control operates, a buzzer will
sound and a message will be displayed on
the Center Display and multi-information
display, to alert the driver. On vehicles with
a head-up display, the head-up display will
display the same message as the
multi-information display.
Depending on the situation, hybrid system output restriction control will operate to
either limit acceleration or restrict output
as much as possible.

If the Parking Support Brake has oper-
ated
If the vehicle is stopped due to operation of
the Parking Support Brake, the Parking
Support Brake will be disabled and the
PKSB OFF indicator will illuminate. If the
Parking Support Brake operates unneces-
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 is disabled due to operation of the
Parking Support Brake, either enable the
system again ( → P.281), or turn the power
switch off and then back to ON mode.
Additionally, if the ob ject becomes no lon-
ger in the traveling direction of the vehicle
or if the traveling direction of the vehicle
changes (such as changing from moving
forward to backing up, or from backing up
to moving forward), the system will be
re-enabled automatically.
■
If “Parking Support Brake Unavailable”
is displayed on th e multi-information
display and the PKSB OFF indicator is
flashing
If the vehicle is stopped due to operation of
the Parking Support Brake, the Parking
Support Brake will be disabled and the
PKSB OFF indicator will illuminate. ●
A sensor may be cove red with ice, snow,
dirt, etc. Remove the ice, snow, dirt, etc.,
from the sensor to return the system to
normal.
Also, due to ice forming on a sensor at
low temperatures, a warning message
may be displayed or the sensor may not
be able to detect an object. Once the ice
melts, the system wi ll return to normal.●
If this message is di splayed only when the
R shift position is selected, the rear cam-
era lens may be dirty. Clean the camera
lens. If this message is displayed in any
forward shift position , a sensor on the
front or rear bumper may be dirty. Clean
the sensors and their surrounding area
on the bumpers. ●
If this message continues to be displayed
even after cleaning the sensor, or is dis-
played even though the sensor is clean,
have the vehicle inspected by your Lexus
dealer. ●
Initialization may not have been per-
formed after a 12-volt battery terminal
was disconnected and reconnected. Ini-
tialize the system. ( → P.284)
If this message continues to be displayed
even after initializati on, have the vehicle
inspected by your Lexus dealer.
■
If a 12-volt battery terminal has been
disconnected 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. D

pedal is not depressed or is depressed late.
Displays a message to urge the driver
to take evasive action when a pedes-
trian is detected in the detection area
behind the vehicle. (A message will
also be displayed on the multi-informa-

If the rear camera sensor detects a pe destrian behind the vehicle while back-
ing up and the system determines that the possibility of colliding with the
detected pedestrian is high, a buzzer will sound. If the system determines that
the possibility of colliding with the dete cted pedestrian is extremely high, the
brakes will be applied automatically to he lp reduce the impact of the collision.

Situations in which the vehicle height
control may not operate properly ●
In the following situations, the vehicle
height may change slowly or may not
change to the correct height:
• When the vehicle comes into contact
with snow, ice, stone, etc.
• When the ambient temperature is low
• When the accumulator tank pressure is
low ●

slope
■
Operating sound of the air suspension
compressor and valves
When the vehicle height is changed, such
as due to passengers entering the vehicle or
cargo being loaded, or when the vehicle
height is changed using the vehicle height
adjustment switch, the air suspension com-
pressor and valves may operate and a
sound may be heard. This does not indicate Electronically modulated air
suspension *
The height of the vehicle when driv-
ing can be selected using the vehi-
cle height adjustment switch. The
selected height level will be main-
tained regardless of the number of
passengers or weight of cargo.
Additionally, settings of the follow-
ing functions can be changed:
