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.)

If the Parking Support Brake has oper-
ated
If the vehicle is stopped due to operation of

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.272), or turn the engine
switch off and then back to IGNITION ON
mode. Additionally, if the object becomes
no longer 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 battery terminal was dis-
connected and reconnected. Initialize the
system. ( → P.275)
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
