WARNING
■Toyota parking assist-sensor
precautions
Observe the following precautions. Failing to do so may result in the vehi -
cle being unable to be driven safely
and possibly cause an accident.
●Do not use the sensor at speeds in
excess of 10 km/h (6 mph).
●The sensors’ detection areas and
reaction times are limited. When moving forward or reversing, check
the areas surrounding the vehicle
(especially the sides of the vehicle) for safety, and drive slowly, using
the brake to control the vehicle’s
speed.
●Do not install acce ssories near the
bumpers as those areas are within the sensors’ detection areas.

4165-5. Using the driving support systems
■The system can be operated when
●The power switch is in ON.
●Toyota parking assist-sensor function is on.
●The vehicle speed is less than about 10 km/h (6 mph).
●The shift lever is in other than P.
■If “Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be covered with ice,
snow, dirt, etc. Rem ove the ice, snow, dirt, etc., from the sensor to return the
system to normal.
Also, due to ice forming on a sensor at low temperatures, a warning message
may be displayed or the sensor may not
be able to detect an object. Once the ice melts, the system will return to normal.
If a warning message is displayed even
if the sensor is cle an, there may be a sensor malfunction. Have the vehicle
inspected by any a uthorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
●The area directly under the bum -
pers is not detected.
Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been
detected once.
■When to disable the function
In the following situations, disable the
function as it may operate even though there is no possibility of a colli -
sion.
●The vehicle is equipped with a com - mercial fender pole, wireless
antenna or fog lights.
●The front or rear bumper or a sen -
sor receives a strong impact.
●A non-genuine Toyota suspension
(lowered suspension, etc.) is
installed.
●Towing eyelets are installed.
●A backlit license plate is installed.
●When using an automatic car wash
■When using the Toyota parking
assist-sensor
In the following situations, the system
may not function correctly due to a
sensor malfunction, etc. Have the vehicle checked by any authorized
Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
●The Toyota parki ng assist-sensor
operation display flashes or shows continuously, a nd a beep sounds
when no objects are detected.
●If the area around a sensor collides
with something, or is subjected to
strong impact.
●If the bumper or grille collides with
something.
●If the display flashes or is displayed continuously and a buzzer does not
sound, except when the mute func -
tion has been turned on.
■Notes when washing the vehicle
Do not apply intensiv e 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 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.

■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

some situations. (automatic
buzzer mute function)
■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.
PKSB (Parking Support
Brake) system

4245-5. Using the driving support systems
ing the accelerator pedal.
■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.

• The Parking Support Brake deter - mines that an imm ediate brake opera-
tion is necessary t o avoid a collision.
■The Parking Support Brake func-
tion (static objects) will stop oper - ating when
The function will stop operating if any of
the following conditions are met:
●Hybrid system output restriction con -
trol • The Parking Support Brake is dis -
abled.
• The system determine s that the colli- sion has become avoidable with nor-
mal brake operation.
• The static object is no longer approxi - mately 2 to 4 m (6 to 13 ft.) away from
the vehicle or in the traveling direction
of the vehicle.
●Brake control
• The Parking Support Brake is dis - abled.
• Approximately 2 seconds have
elapsed since the vehicle was stopped by brake control.
• The brake pedal is depressed after
the vehicle is stopped by brake con - trol.
• The static object is no longer approxi -
mately 2 to 4 m (6 to 13 ft.) away from the vehicle or in the traveling direction
of the vehicle.
■Detection range of the Parking Sup -
port Brake function (static objects)
The detection range of the Parking Sup -
port Brake function ( static objects) dif-
fers from the detection range of the Toyota parking assist-sensor. ( →P.418)
Therefore, even if the Toyota parking
assist-sensor detect s an object and pro-
vides a warning, the Parking Support Brake function (static objects) may not
start operating.
■Objects that the Parking Support
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 reflectors of sonic waves
●Objects which are not perpendicular
to the ground, are not perpendicular 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
●Sharply-angled objects
●Tall objects with upper sections pro-
jecting outwards in the direction of
your vehicle
■Situations in which the Parking Support Brake function (static
objects) may not operate
When the shift lever is in N
■Toyota parking assist-sensor buzzer
Regardless of whether the Toyota park -
ing assist-sensor function is enabled or not ( →P.415), if the Parking Support
Brake function (static objects) is enabled
( →P.421), the front or rear sensors detect an object and brake control and
hybrid system output r estriction control
are performed, the Toyota parking assist-sensor buzzer will sound to notify
the driver of the approximate distance to
the object.
■Situations in which the Parking Support Brake function (static
objects) may operate even if there
is no possibility of a collision
In some situations, s uch as the follow-
ing, the Parking Support Brake function
(static objects) may operate even
though there is no possibility of a colli - sion.
