audio system or air flow noise of
the air conditioning system.
●It may be difficult to hear the
sound of this system due to the
buzzers of other systems.
■Objects which the system may
not properly detect
The shape of the object may pre-
vent the sensor from detecting it.
Pay particular attention to the fol-
lowing objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials
that absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections
projecting outwards in the direc-
tion of your vehicle
People may not be detected if they
are wearing certain types of cloth-
ing.
■Situations in which the system
may not operate properly
Certain vehicle conditions and the
surrounding environment may affect
the ability of a sensor to correctly
detect objects. Particular instances
where this may occur are listed
below.
●There is dirt, snow or ice on a sen-
sor. (Cleaning the sensors will
resolve this problem.)
●A sensor is frozen. (Thawing the
area will resolve this problem.)
In especially cold weather, if a
sensor is frozen the sensor dis-
play may be displayed abnor-
mally, or objects, such as a wall,
may not be detected.
●When a sensor or the area around
a sensor is extremely hot or cold.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of ot her vehicles or
other devices which produce ultra-
sonic waves are near the vehicle.
●A sensor is coated with a sheet of
spray or heavy rain.
●If objects draw too close to the
sensor.
●When a pedestrian is wearing
clothing that does not reflect ultra-
sonic waves (ex. skirts with gath-
ers or frills).
●When objects that are not perpen-
dicular to the ground, not perpen-
dicular to the vehicle traveling
direction, uneven, or waving are in
the detection range.
●Strong wind is blowing.
●When driving in inclement weather
such as fog, snow or a sandstorm.
●When an object that cannot be
detected is between the vehicle
and a detected object.
●If an object such as a vehicle,
motorcycle, bicycle or pedestrian
cuts in front of the vehicle or runs
out from the side of the vehicle.
●If the orientation of a sensor has
been changed due to a collision or
other impact.
●When equipment that may
obstruct a sensor is installed, such
as a towing eyelet, bumper pro-
tector (an additional trim strip,
etc.), bicycle c arrier, or snow
plow.

●If the front of the vehicle is raised
or lowered due to the carried load.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning.
●When tire chains, a compact
spare tire or an emergency tire
puncture repair kit are used.
■Situations in which the system
may operate even if there is no
possibility of a collision
In some situations, such as the fol-
lowing, the system may operate
even though there is no possibility of
a collision.
●When driving on a narrow road.
●When driving toward a banner,
flag, low-hanging branch or boom
barrier (such as those used at rail-
road crossings, toll gates and
parking lots).
●When there is a rut or hole in the
surface of the road.
●When driving on a metal cover
(grating), such as those used for
drainage ditches.
●When driving up or down a steep
slope.
●If a sensor is hit by a large amount
of water, such as when driving on
a flooded road.
●There is dirt, snow, water drops or
ice on a sensor. (Cleaning the
sensors will resolve this problem.)
●A sensor is coated with a sheet of
spray or heavy rain.
●When driving in inclement weather
such as fog, snow or a sandstorm.
●When strong winds are blowing.
●When vehicle horns, vehicle
detectors, motorcycle engines, air
brakes of large vehicles, the clear-
ance sonar of ot her vehicles or
other devices which produce ultra-
sonic waves are near the vehicle.
●If the front of the v ehicle is raised
or lowered due to the carried load.
●If the orientation of a sensor has
been changed due to a collision or
other impact.
●The vehicle is approaching a tall
or curved curb.
●Driving close to columns (H-
shaped steel beams, etc.) in multi-
story parking garages, construc-
tion sites, etc.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or
is malfunctioning.
●On an extremely bumpy road, on
an incline, on gravel, or on grass.
●When tire chains, a compact
spare tire or an emergency tire

The Parking Support Brake
system consists of the fol-
lowing functions that oper-
ate when driving at a low
speed or backing up, such
as when parking. When the
system determines that the
possibility of a collision
with a detected object is
high, a warning operates to
urge the driver to take eva-
sive action. If the system
determines that the possi-
bility of a collision with a
detected object is extremely
high, the brakes are auto-
matically applied to help
avoid the collision or help
reduce the impact of the
collision.

Brake) system
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 n ot operate.
The detection cap abilities 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 comple tely. 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 Suppor t Brake as the
system may opera te even though
there is no possibility of a colli-
sion.

2964-5. Using the driving support systems
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.106, 117)
When the Parking Support Brake is
disabled, the PKSB OFF indicator
( P.88) 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 been turned to OFF.

■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 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.296), 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 “PKSB Unavailable”/“Parking
Support Brake Unavailable” is
displayed on the multi-informa-
tion display and the PKSB OFF
indicator illuminates
●If “Parking Assist Unavailable
Clean Parking Assist Sensor” is
displayed simultaneously, a sen-
sor 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.
●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.

objects)
*
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.
