■If “Parking Assist Unavailable” is
displayed on the multi-information display (vehicles with PKSB)
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 nor-
mal.
■Sensor detection information
●The sensor’s detec tion areas are lim-
ited to the areas aro und the vehicle’s front and rear bumpers.
●The following situations may occur during use.
• Depending on the shape of the object
and other factors, t he detection dis- tance may shorten, or detection may
be impossible.
• Detection may be impossible if static objects draw too close to the sensor.
• There will be a shor t delay between
static object detec tion and display (warning buzzer sounds). Even at low
speeds, there is a possibility that the
object will come withi n 25 cm (9.8 in.) before the display is shown and the
warning buzzer sounds.
• It might be difficu lt to hear the buzzer due to the volume of the audio system
or air flow noise of the air conditioning
system. • It may be difficult to hear the sound of
this system due t o the buzzers of
other systems.
■Conditions under which the func -
tion may no t function correctly
Certain vehicle c onditions and the sur-
rounding 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 sensor.
(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 display may be displayed abnormally, or objects, such
as a wall, may not be detected.
●A sensor is covered in any way.
●When a sensor or the area around a sensor is extremely hot or cold.
●On an extremely bumpy road, on an incline, on grav el, or on grass.
●The vicinity of the vehicle is noisy due to vehicle horns, motorcycle engines,
air brakes of large vehicles, or other
loud noises pro ducing ultrasonic waves.
●There is another vehicle equipped with parking assist sensors in the
vicinity.
●A sensor is coated with a sheet of
spray or heavy rain.
●If a sensor is hit by a large amount of
water, such as when driving on a
flooded road.
●If the vehicle is significantly tilted.
●The vehicle is approaching a tall or
curved curb.
●If objects draw too close to the sensor.
■Objects which may not be properly
detected
The shape of the object may prevent the sensor from detecting it. Pay particular
attention to the following objects:
●Wires, fences, ropes, etc.
●Cotton, snow and other materials that
absorb sound waves
●Sharply-angled objects
●Low objects
●Tall objects with upper sections pro- jecting outwards in the direction of
your vehicle

4185-5. Using the driving support systems
People may not be dete cted if they are
wearing certain types of clothing.
■Detection range of the sensors
Approximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 60 cm (2.0 ft.)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect objects that
are extremely clos e to the vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
■Distance display
When an object is detected by a sensor, the approximate distanc e to the
object will be displayed on the m ulti-information display, navigation system
(if equipped) or multimedia syst em (if equipped) screen. (As the distance to
the object becomes s hort, the distance segments may blink.)
The images may differ from that shown in the illustrations.
Approximate distance to object

■Buzzer operation and dis-
tance to an object
A buzzer sounds when the sensors
are operating.
 The buzzer beeps faster as the
vehicle approaches an object.
When the vehicle comes within
approximately 30 cm (1.0 ft.) of
the object, the buzzer sounds
continuously
 When 2 or more sensors simulta-
neously detect a static object,
the buzzer sounds for the near -
est object.
 Even when the sensors are oper-
ating, the buzze r will be muted in

■Muting the buzzer sound (vehicles
with PKSB)
●Automatic buzzer mute function
Even when the sensor s are operating,
the buzzer will be muted in the following
situations:
• The distance between the vehicle and the detected objec t does not become
shorter (except when the distance
between the vehicle and object is 30 cm [1.0 ft.] or less).
• Your vehicle is moving away from the
object. • There are no detec table objects enter-
ing the path of your vehicle.
However, if another object is detected or
the situation changes while the buzzer is
muted, the buzzer begins sounding
again.
●To mute the buzzer sound
The buzzer can be temporarily muted by
pressing of the meter control
switches while a suggestion that says
mute is available is shown on the multi-
information display.
●When the mute is canceled
Mute will be automatic ally canceled in
the following situations.
• When the shift position is changed • When the vehicle s peed has reached
or exceeded a certain speed
• When the Toyota par king assist is turned off once and turned on again
• When the power switch is turned off
once and turned to ON again

PKSB (Parking Support
Brake)*
The Parking Support Brake
system consists of the follow -
ing functions that operate
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 oper-
ates to urge the driver to take
evasive action. If the system
determines that the possibility
of a collision with a detected
object is extrem ely high, the
brakes are automatically
applied to help avoid the colli -
sion or help red uce the impact
of the collision.

The Parking Support Brake can be
enabled/disabled on the screen
of the multi-information display. All
of the Parking Support Brake func -
tions (static objects and rear-cross -
ing vehicles) are enabled/disabled
simultaneously. ( →P.186)
When the Parking Support Brake is dis-
abled, the PKSB OFF indicator
( →P.171) illuminates on the multi-infor-
mation display.
To re-enable the system, select on
the multi-information display, select
and turn it on.
If the system is disabl ed, it will remain
off even if the power switch is turned to
ON after the power switch has been
turned off.
WARNING
■Limitations of the Parking Sup -
port Brake system
Do not overly rely on the system, as doing so may lead to an accident.
Always drive while checking the
safety of the surroundings of the vehi - cle.
Depending on the v ehicle and road
conditions, weather, etc., the system
may not operate.
The detection capabilities of sensors
and radars are limited. Always drive
while checking the safety of the sur- roundings of the vehicle.
●The driver is solely responsible for safe driving. Always drive carefully,
taking care to observe your sur -
roundings. The Parking Support Brake system is designed to pro-
vide support to lessen the severity
of collisions. However, it may not operate in som e situations.
●The Parking Support Brake system is not designed to stop the vehicle
completely. Additionally, even if the
system has stopped the vehicle, it is necessary to depress the brake
pedal immediately as brake control
will be canceled after approximately 2 seconds.
●Do not attempt to test the operation of the Parking Support Brake sys -
tem yourself such as intentionally
driving to a vehicle or wall. Depending on the situations, the
system may not ope rate properly,
possibly leading to an accident.
NOTICE
■If “PKSB Unavailable” is dis -
played on the multi-information
display and the PKSB OFF indi - cator illuminates
If this message is displayed immedi -
ately after the power switch is changed to ON, ope rate the vehicle
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 syst em does not return
to normal after driving for a while, clean the sensors and their surround -
ing area on the bumpers.)

■Re-enabling the Parking 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.421), 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
direction of the vehicle changes (such as changing from moving forward to
backing up, or from backing up to mov -
ing forward), the system will be re- enabled automatically.
■If “Parking Support Brake Unavail -
able” is displayed on the multi-
information display and the PKSB OFF indicator illuminates
●If “Clean Parking Assist Sensor” is displayed simultaneously, a sensor
may be covered with ice, snow, dirt,
etc. In this case, remove the ice, snow, dirt, etc., from the sensor to
return the system to normal. If this
message is shown even after remov - ing dirt from the sensor, or shown
when the sensor was not dirty to begin
with, have the vehi cle inspected at any authorized Toy ota retailer or
Toyota authorized repairer, or any reli -
able repairer.
●If “Parking Assist Unavailable” is dis -
played 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 w ill return to nor-
mal.
*: If equipped
This function will operate in situa -
tions such as the following if an
object is detected in the traveling
direction of the vehicle.
Parking Support Brake
function (static objects)*
If the sensors detect a static
object, such as a wall, in the
traveling direction of the vehi -
cle and the system determines
that a collision may occur due
to the vehicle suddenly moving
forward due to an accidental
accelerator pedal operation,
the vehicle moving the unin -
tended 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.

WARNING
■To ensure the Parking Support
Brake can operate properly
Observe the following precautions regarding the sensors ( →P.414). Fail-
ure to do so may cause a sensor to
not operate proper ly, and may cause an accident.
●Do not modify, disassemble or paint the sensors.
●Do not replace a s ensor with a part other than a genuine part.
●Do not subject a sensor or its sur - rounding area to a strong impact.
●Do not damage the sensors, and always keep them clean.

■The Parking Support Brake func- tion (static object) will operate
when
The function will operate when the
PKSB OFF indicator is not illuminated ( →P.170, 171) and all of the following
conditions are met:
●Hybrid system outpu t restriction con-
trol
• The Parking Support Brake is enabled.
• The vehicle speed is approximately 15
km/h (9 mph) or less. • There is a static object in the traveling
direction of the v ehicle and approxi-
mately 2 to 4 m (6 to 13 ft.) away. • The Parking Support Brake deter -
mines that a stronger-than-normal

WARNING
●If the area around a radar sensor is
subjected to an im pact, the system
may not operate properly due to a sensor malfunction. Have the vehi -
cle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Handling the suspension
Do not modify the suspension, as changes to the height or inclination of
the vehicle may pr event the sensors
from detecting objects correctly or cause the system to not operate or
operate unnecessarily.
■If the Parking Support Brake
function (static objects) operates
unnecessarily, such as at a rail - road crossing
In the event that the Parking Support
Brake function (sta tic objects) oper- ates unnecessarily, such as at a rail-
road crossing, brake control will be
canceled after appr oximately 2 sec- onds, allowing you to proceed forward
and leave the area, brake control can
also be canceled by depressing the brake pedal. Depressing the acceler -
ator pedal after brake control is can -
celed will allow you to proceed forward and leav e the area.
■Notes when washing the vehicle
Do not apply intensive bursts of water
or steam to the sensor area.
Doing so may resul t 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 malfunc - tion.
●When using steam to clean the vehicle, do not direct steam too
close to the sensors as doing so
may cause a sensor to malfunction.
■When to disable the Parking Sup - port Brake
In the following situations, disable the
Parking Support Brake as the system may operate even t hough there is no
possibility of a collision.
●When inspecting t he 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 modi -
fied 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 instal led, such as a tow-
ing eyelet, bumper protector (an
additional trim st rip, etc.), bicycle carrier, or snow plow
●When using an autom atic car wash
