●The engine switch is in IGNITION ON
mode.
●RCD function is on.

The buzzer volume can be adjusted on the
multi-information display. ( P.215)
The RCD buzzer sound is linked with the
RCTA buzzer.
■If “Rear Camera Detection Unavailable
Remove the Dirt of Rear Camera” is
displayed on the multi-information dis-
play
A rear camera lens may be dirty or covered
with snow or ice. In such cases, if it is
removed from the rear camera lens, the
system should return to normal. (It may be
necessary to drive the vehicle for some time
before the system returns to normal.)
■If “Rear Camera Detection Unavail-
able” is displayed on the multi-informa-
tion display
●If this message is displayed after the bat-
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 displayed only when the
shift lever is in R, the rear camera lens
may be dirty. Clean the rear camera lens.

2344-5. Using the driving support systems
The Parking Support Brake can be
enabled/disabled on the multi-infor-
mation display. All of the Parking Sup-
port Brake functions (static objects,
rear-crossing vehicles, and rear
pedestrians) are enabled/disabled
simultaneously.
Use the meter control switches to
enable/disable the parking support
brake. (P.77)
1 Press or to select .
2 Press or to select and
then press “OK”.
When the Parking Support Brake is dis-
abled, the PKSB OFF indicator ( P.66)
illuminates on the multi-information dis-
play.
To re-enable the system, select on the
multi-information display, select and
turn it on. If the system is disabled, it will
remain off even if the engine switch is
turned to IGNITION ON mode after the
engine switch has been turned off. 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
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, engine output
restriction control will operate to either
limit acceleration or restrict output as
much as possible.
Engine output restriction control is
operating (acceleration restriction)
Acceleration greater than a certain
amount is restricted by the system.
Center Display (Panoramic view monitor):
No warning displayed

The system has determined that stronger-
than-normal brake operation is necessary.
Center Display (Panoramic view monitor):

If this message is displayed immediately
after the engine switch is changed to
IGNITION ON mode, operate the vehi-
cle carefully, paying 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 after
driving for a while, clean the rear camera
lens.)

If the Parking Support Brake determines that a collision with a detected object or
pedestrian is possible, the engine output will be restricted to restrain any increase
in the vehicle speed. (Engine output restriction control: See figure 2 below.)
Additionally, if the accelerator pedal contin
ues to be depressed, the brakes will be
applied automatically to reduce the vehicle speed. (Brake control: See figure 3
below.)

■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 Parking Support Brake
To re-enable the Parking Support Brake
when it has been disabled due to system
operation, perform any of the following
operations. At this time, the PKSB OFF
indicator will turn off. ( P.66)
●Turn the PKSB system on ( P.234)
●Turn the engine switch off, and then back
to IGNITION ON mode
●Shift the shift lever to P
●Drive with no operation targets in the
traveling direction of the vehicle
●Change the traveling direction of the
vehicle*

■If “Parking Support Brake Unavailable”
is displayed on the multi-information
display and the PKSB OFF indicator is
flashing
If this message is displayed only when the
shift lever is in R, the rear camera lens may
be dirty. Clean the camera lens. If this mes-
sage is displayed when the shift lever is in
any position other than R, a sensor on the
front or rear bumper may be dirty. Clean
the sensors and their surrounding area on
the bumpers.
■If “Parking Support Brake Unavailable”
and “Parking Assist Unavailable Clean

the multi-information display and the

●A sensor may be covered with ice, snow,
dirt, etc. In this case, remove the ice,
snow, dirt, etc., from the sensor to return
the system 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 at your Lexus dealer.
●A sensor may be frozen. Once the ice
melts, the system will return to normal.

tions are met:
●Engine output restriction control
• The Parking Support Brake is enabled.
• The vehicle speed is approximately 9
mph (15 km/h) or less.
• There is a static ob ject in the traveling
direction of the vehicle and approxi-
mately 6 to 13 ft. (2 to 4 m) away.
• The Parking Support Brake determines that a stronger-than-normal brake oper-
ation is necessary to avoid a collision.
●Brake control
• Engine output restriction control is oper- ating.
• The Parking Support Brake determines
that an immediate brake operation is
necessary to avoid a collision.
■The Parking Support Brake function
(static objects) will stop operating when
The function will stop operating if any of the
following conditions are met:
●Engine output restriction control
• The Parking Support Brake is disabled.
• The system determines that the collision has become avoidable with normal brake
operation.
• The static object is no longer approxi- mately 6 to 13 ft. (2 to 4 m) away from the
vehicle or in the trav eling 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 approxi- mately 6 to 13 ft. (2 to 4 m) away from the
vehicle or in the trav eling 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.220) Therefore, even if the
intuitive parking assist detects an object and
provides a warning, the Parking Support
Brake function (static objects) may not start operating.

the Parking Support
Brake function (static objects) may not
operate

Parking Support Brake function (rear-crossing vehicles)*
If a rear radar sensor detects a vehicle approaching from the right or left at the
rear of the vehicle and the system determines that the possibility of a collision
is high, this function will perform brake control to reduce the likelihood of an
impact with the approaching vehicle.

ating when
The function will stop operating if any of the
following conditions are met:

■Detection area of the Parking Support
Brake function (rear-crossing vehicles)
The detection area of the Parking Support
Brake function (rear-crossing vehicles) dif-
fers from the detection area of the RCTA
function ( P.225). Therefore, even if the
RCTA function detects a vehicle and pro-
vides an alert, the Parking Support Brake
function (rear-crossing vehicles) may not
start operating.
