Driving
The Parking Support Brake can
be enabled/disabled on the
screen of the multi-information
display. All of the Parking Sup-
port Brake functions (static
objects and rear-crossing vehi-
cles) are enabled/disabled
simultaneously. (P.108)
When the Parking Support Brake is
disabled, the PKSB OFF indicator
(  P.91) illuminates on the multi-
information display.
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 power switch
is turned to ON after the power
switch has bee n turned off.
WARNING
■Limitations of the Parking
Support Brake system
Do not overly rely on the system,
as doing so may lead to an acci-
dent.
Always drive while checking the
safety of the su rroundings of the
vehicle.
Depending on the vehicle and
road conditions, weather, etc., the
system may not operate.
The detection capa bilities of sen-
sors and radars are limited.
Always drive while checking the
safety of the su rroundings of the
vehicle.
●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 sys-
tem is not designed to stop the
vehicle completely. Addition-
ally, even if the system has
stopped the vehicle, it is neces-
sary to depress the brake pedal
immediately as brake control
will be canceled after approxi-
mately 2 seconds.
NOTICE
■If “Parking Support Brake
Unavailable” is displayed on
the multi-information display
and the PKSB OFF indicator

If this message is displayed
immediately after the power
switch is changed to ON, operate
the vehicle carefully, paying atten-
tion to your surroundings. It may
be necessary to drive the vehicle
for a certain amount of time
before the system returns to nor-
m a l . ( I f t h e s y s t e m d o e s n o t r e t u r n

■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 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
