depressing the brake pedal or wait-
ing for approximately 2 seconds for
it to automatically be canceled.
Then, the vehicle can be operated
by depressing the accelerator pedal.
■Re-enabling the Parking Sup-
port 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.299), or turn the power
switch to OFF and then back to ON.
Additionally, if the object becomes
no longer in the traveling direction of
the vehicle or if the traveling direc-
tion 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” i s displayed on
the multi-information display
and the PKSB OFF indicator is
flashing
●If this message is displayed, a
sensor on the front or rear bumper
may be dirty. Clean the sensors
and their surrounding area on the
bumpers.
●Initialization ma y not have been
performed after a 12-volt battery
terminal was dis connected and
reconnected. Initialize the sys-
tem. ( P.302)
If this message continues to be
displayed even after initialization,
have the vehicle inspected by
your Toyota dealer.
■If “Parking Support Brake
Unavailable” and “Parking
Assist Unavailable Clean Park-
ing Assist Sensor” are dis-
played on the multi-information
display and the PKSB OFF indi-
cator is flashing
●A sensor may be covered with ice,
snow, dirt, etc. In this case,
remove the ice, s now, dirt, etc.,
from the sensor to return the sys- tem 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 Toyota dealer.
●A sensor may be frozen. Once the
ice melts, the sys tem will return to
normal.
●Water may be continuously flow-
ing over the sensor surface, such
as in a heavy rain. When the sys-
tem determines that it is normal,
the system will retu rn to normal.
■If a 12-volt battery terminal has
been disconnected and recon-
nected
The system needs to be initialized.
To initialize 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.
■When traveling at a low speed and the brake pedal is not
depressed, or is depressed late
Parking Support Brake fu nction (static objects)*
If the sensors detect a static object, such as a wall, in the t rav-
eling direction of the vehicle and the system determines that a
collision may occur due to the vehicle suddenly moving for-
ward due to an accidental 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

3044-5. Using the driving support systems
■When the accelerator pedal is depressed excessively
■When the vehicle moves in the unintended direction due to
the wrong shift position being selected
 P.291
Types of sensorsWARNING
■To ensure the Parking Sup-
port Brake can operate prop-
erly
Observe the following precautions
regarding the sensors ( P.291).
Failure to do so may cause a sen-
sor to not operate properly, and
may cause an accident.
●Do not modify, d isassemble or
paint the sensors.

WARNING
●Do not replace a sensor with a
part other than a genuine part.
●Do not subject a sensor or its
surrounding area to a strong
impact.
●Do not damage the sensors,
and always keep them clean.
●If the area around a radar sen-
sor is subjected to an impact,
the system may not operate
properly due to a sensor mal-
function. Have the vehicle
inspected by your Toyota
dealer.
■Handling the suspension
Do not modify the suspension, as
changes to the height or inclina-
tion of the vehicle may prevent
the sensors from detecting
objects correctly or cause the sys-
tem to not operate or operate
unnecessarily.
■If the Parking Support Brake
function (static objects) oper-
ates unnecessarily, such as
at a railroad crossing
In the event that the Parking Sup-
port Brake function (static objects)
operates unnecessarily, such as
at a railroad cross ing, brake con-
trol will be cancele d after approxi-
mately 2 seconds, allowing you to
proceed forward and leave the
area, brake control can also be
canceled by depressing the brake
pedal. Depressing the accelera-
tor pedal after brake control is
canceled will allow you to proceed
forward and leave the area.
■Notes when washing the vehi-
cle
Do not apply intensive bursts of
water or steam to the sensor
area.
Doing so may result in the sensor
malfunctioning.
●When using a high pressure
washer to wash the vehicle, do
not spray the sensors 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 sensor to malfunc-
tion.
■When to disable the Parking
Support Brake
In the following situations, disable
the Parking Suppor t Brake as the
system may opera te even though
there is no possibility of a colli-
sion.
●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 additional trim
strip, etc.), bicycle carrier, or
snow plow
●When using an automatic car
wash

■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 intuiti ve parking assist.
(  P.296) Therefore, even if the
intuitive parking assist detects an
object and provides a warning, the
Parking Support Brake function
(static objects) may not start operat-
ing.
■Objects that the Parking Sup-
port Brake function (static
objects) may not detect
The sensors may not be able to
detect certain objects, such as the
following:
●Pedestrian
●Cotton, snow, and other materials
that are poor re flectors of sonic
waves
●Objects which are not perpendicu-
lar to the ground, are not perpen-
dicular 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 e xtremely close
to the bumper
