■Buzzer operation and dis-
tance to an object
A buzzer sounds when the sen-
sors are operating.
 The buzzer beeps faster as
the vehicle approaches an
object.
When the vehicle comes
within approximately 1.0 ft.
(30 cm) of the object, the
buzzer sounds continuously.
 When 2 or more sensors
simultaneously detect a static
object, the buzzer sounds for
the nearest object.
 Even when the sensors are
operating, the buzzer will be muted in some situations.
(automatic buzzer mute func-
tion)
■Muting the buzzer sound
●Automatic buzzer mute function
Even when the sensors are operat-
ing, the buzz er will be muted in the
following situations:
• The distance between the vehicle and the detected object does not
become shorter (except when the
distance between the vehicle and
object is 1.0 ft. [30 cm] or less).
• Your vehicle is moving away from
the object.
• There are no detectable objects entering the path o f your vehicle.
However, if another object is
detected or the situation changes
while the buzzer is muted, the

WARNING
■Cautions regarding the use of
the 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 surroundings 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 surroundings 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.
●It is extremely dangerous to
check the system operations by
intentionally driving the vehicle
into the direction of a wall, etc.
Never attempt such actions.
■When to disable the Parking
Support Brake
In the following situations, disable
the Parking Support Brake as the
system may operate even though
there is no poss ibility 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 automatic car
washing devices.
●If the vehicle cannot be driven in
a stable manner, such as when
the vehicle has been in an acci-
dent or is malfunctioning.
●When the vehicle is driven in a
sporty manner or off-road.
●When the tires are not properly
inflated.
●When the tires are very worn.
●When tire chains, a compact
spare tire or an emergency tire
puncture repair kit are used.
●When your vehicle is towing a
trailer or during emergency tow-
ing.

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.191, 203)
When the Parking Support Brake is
disabled, the PKSB OFF indicator
( P.170) illuminate s on the multi-
information display.
To re-enable the system, select
on the multi-inform ation 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 been turned off.
If the hybrid system output
restriction control or brake con-
trol operates, a buzzer will
sound and a message will be
displayed on the multi-informa-
tion display, head-up display (if
equipped) or Multimedia Dis-
play, to alert the driver.
Depending on the situation, hybrid
system output restriction control will
operate to either limit acceleration
or restrict output as much as possi-
ble.
 Hybrid system output restric-
tion control is operating
(acceleration restriction)
Acceleration greater than a certain
amount is restric ted by the system.
Multi-information display and head-
up display: “Object Detected Accel-
eration Reduced” (no warning dis-
played on the head-up display)
Multimedia Display: No warning
displayed
PKSB OFF indicator: Not illumi-
nated
Buzzer: Does not sound
 Hybrid system output restric-
tion control is operating (out-
put restricted as much as
possible)
The system has determined that
stronger-than-normal brake opera-
tion is necessary.
NOTICE
■If “Parking Support Brake
Unavailable” is displayed on
the multi-information display
and the PKSB OFF indicator
illuminates
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-
mal. (If the system does not return
to normal after driving for a while,
clean the sensors and their sur-
rounding area on the bumpers.)

■If the Parking Support Brake
has operated
If the vehicle is stopped due to oper-
ation of the Parki ng Support Brake,
the Parking Suppor t Brake will be
disabled and the PKSB OFF indica-
tor will illuminate. If the Parking Sup-
port Brake operates unnecessarily,
brake control can be canceled by depressing the brake pedal or wait-
ing for approximate
ly 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.397), 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), t he system will be
re-enabled automatically.
■If “Parking Support Brake
Unavailable” is displayed on
the multi-information display
and the PKSB OFF indicator
illuminates
●If “Clean Parking Assist Sensor” is
displayed simultaneously, a sen-
sor may be covered with ice,
snow, dirt, etc. In this case,
remove the ice, snow, dirt, etc.,
from the sensor t o 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.
●If “Parking Assist Unavailable” is
displayed simultaneously, water
may be continuously flowing over
the sensor surface, such as in a
heavy rain. When the system
determines that it is normal, the
system will return to normal.

If the sensors detect a static
object, such as a wall, in the
traveling direction of the
vehicle and the system
determines that a collision
may occur due to the vehi-
cle suddenly moving for-
ward due to an accidental
accelerator pedal opera-
tion, 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.
