The buzzer volume can be adjusted on the
multi-information display. (  P.256)■
Conditions under which the RCTA func-
tion will not detect a vehicle
The RCTA function is not designed to
detect the following types of vehicles and/or
objects: ●
Vehicles approaching from directly
behind●
Vehicles backing up in a parking space
next to your vehicle●
Vehicles that the sensors cannot detect
due to obstructions
●
Guardrails, walls, signs, parked vehicles
and similar stationary objects *
●
Small motorcycles, bicycles, pedestrians,
etc. *
●
Vehicles moving away from your vehicle
●
Vehicles approaching from the parking
spaces next to your vehicle *
*
: Depending on the conditions, detection
of a vehicle and/or object may occur. ■
Conditions under which the RCTA func-
tion may not function correctly ●
The RCTA function may not detect vehi-
cles correctly in the following situations:
• When a sensor is misaligned due to a
strong impact to the sensor or its sur-
rounding area
• When mud, snow, ice, a sticker, etc. is
covering a sensor or its surrounding area
on the rear bumper
• When driving on a road surface that is
wet with standing water during bad
weather, such as heavy rain, snow, or fog
• When multiple vehicles are approaching
with only a small gap between each vehi-
cle
• If a vehicle is approaching the rear of
your vehicle rapidly
• When a towing eyelet is installed to the
rear of the vehicle.
• When backing up on a slope with a sharp
change in grade
• When backing out of a shallow angle
parking spot
• Immediately after the RCTA function is
turned on
• Immediately after the engine is started

Driving with the RCTA function on
• When the sensors cannot detect a vehi-
cle due to obstructions
●
Instances of the RCTA function unneces-
sarily detecting a vehicle and/or object
may increase in the following situations:
• When a vehicle passes by the side of your
vehicle
• When the parking space faces a street
and vehicles are being driven on the
street
• When the distance between your vehicle
and metal objects, such as a guardrail,
wall, sign, or parked vehicle, which may
reflect electrical waves toward the rear of
the vehicle, is short
• When a towing eyelet is installed to the
rear of the vehicle *

tery has been disconnected and recon-
nected, fully turn the steering wheel to
the left and then the right on level ground.
●
If this message is di splayed only when the
R shift position is selected, the rear cam-
era lens may be dirty. Clean the rear
camera lens.

static objects, such as a wall, in the
detection area when driving at a low
speed or backing up. (  P.276)■

(  P.286)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 engine swit ch is changed to
IGNITION ON mode, operate the vehi-
cle carefully, paying attention to your sur-
roundings. 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 after
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.81)
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.68)
illuminates.
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 engine switch
off and then to IGNITION ON mode.
If the engine output restriction control or
brake control operates, a buzzer will sound
and a message will be displayed on the
Center Display and multi-information dis-
play, 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, engine output
restriction control will operate to either limit acceleration or restrict output as
much as possible.

amount is restricted by the system.

in the vehicle speed. (Engine output restriction control: See figure 2.)
Additionally, if the accelerator pedal contin ues to be depressed, the brakes will be
applied automatically to redu ce the vehicle speed. (Brake control: See figure 3.)

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. ■
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 battery terminal was dis-
connected and reconnected. Initialize the
system. (  P.274)
If this message continues to be displayed
even after initializati on, 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. D
