Driving
QThe system can be operated when
OThe power switch is in ON.
OToyota parking assist-sensor function
is on.
OThe vehicle speed is less than about
10 km/h (6 mph).
OThe shift lever is in other than P.
QIf “Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be covered with ice,
snow, dirt, etc. Remove 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 clean, there may be a sensor malfunction. Have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
QIf “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.
WARNING
ODo not attach a sticker or install an electronic component, such as a
backlit license plate (especially fluo- rescent type), fog lights, fender pole or wireless antenna near a radar
sensor.
ODo not subject the surrounding area
of the sensor to a strong impact. If subjected to an impact, have the vehicle inspected by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer. If the front or rear bumper needs to
be removed/installed or replaced, contact any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
ODo not modify, disassemble or paint
the sensors.
ODo not attach a license plate cover.
OKeep your tires properly inflated.
QWhen 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.
OFailing to observe the warnings
above.

QSensor detection information
OThe sensor’s detection areas are lim-
ited to the areas around the vehicle’s
front and rear bumpers.
OThe following situations may occur
during use.
• Depending on the shape of the object
and other factors, the 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 short delay between
static object detection and display
(warning buzzer sounds). Even at low
speeds, there is a possibility that the
object will come within 25 cm (9.8 in.)
before the display is shown and the
warning buzzer sounds.
• It might be difficult 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 to the buzzers of
other systems.
QObjects which the system may not
properly detect
The shape of the object may prevent the
sensor from detecting it. Pay particular
attention to the following objects:
OWires, fences, ropes, etc.
OCotton, snow and other materials that
absorb sound waves
OSharply-angled objects
OLow objects
OTall objects with upper sections pro-
jecting outwards in the direction of
your vehicle
People may not be detected if they are
wearing certain types of clothing.
QSituations in which the system may
not operate properly
Certain vehicle conditions 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.
OThere is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
OA 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.
OWhen a sensor or the area around a
sensor is extremely hot or cold.
OOn an extremely bumpy road, on an
incline, on gravel, or on grass.
OWhen vehicle horns, vehicle detec-
tors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of
other vehicles or other devices which
produce ultrasonic waves are near the
vehicle.
OA sensor is coated with a sheet of
spray or heavy rain.
OIf objects draw too close to the sensor.
OWhen a pedestrian is wearing clothing
that does not reflect ultrasonic waves
(ex. skirts with gathers or frills).
OWhen objects that are not perpendicu-
lar to the ground, not perpendicular to
the vehicle traveling direction,
uneven, or waving are in the detection
range.
OStrong wind is blowing.
OWhen driving in inclement weather
such as fog, snow or a sandstorm.
OWhen an object that cannot be
detected is between the vehicle and a
detected object.
OIf an object such as a vehicle, motor-
cycle, bicycle or pedestrian cuts in
front of the vehicle or runs out from

the side of the vehicle.
OIf the orientation of a sensor has been
changed due to a collision or other
impact.
OWhen equipment that may obstruct a
sensor is installed, such as a towing
eyelet, bumper protector (an addi-
tional trim strip, etc.), bicycle carrier,
or snow plow.
OIf the front of the vehicle is raised or
lowered due to the carried load.
OIf the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or is
malfunctioning.
OWhen tire chains, a compact spare
tire or an emergency tire puncture
repair kit are used.
QSituations in which the system may
operate even if there is no possibil-
ity of a collision
In some situations, such as the follow-
ing, the system may operate even
though there is no possibility of a colli-
sion.
OWhen driving on a narrow road.
OWhen driving toward a banner, flag,
low-hanging branch or boom barrier
(such as those used at railroad cross-
ings, toll gates and parking lots).
OWhen there is a rut or hole in the sur-
face of the road.
OWhen driving on a metal cover (grat-
ing), such as those used for drainage
ditches.
OWhen driving up or down a steep
slope.
OIf a sensor is hit by a large amount of water, such as when driving on a
flooded road.
OThere is dirt, snow, water drops or ice
on a sensor. (Cleaning the sensors
will resolve this problem.)

OAutomatic buzzer mute function
Even when the sensors are operating,
the buzzer 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 30
cm [1.0 ft.] or less).
• Your vehicle is moving away from the
object.
• There are no detectable 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.
OTo 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.
OWhen the mute is canceled
Mute will be automatically canceled in
the following situations.
• When the shift position is changed• When the vehicle speed has reached
or exceeded a certain speed
• When the Toyota parking assist is
turned off once and turned 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 extremely high, the
brakes are automatically
applied to help avoid the colli-
sion or help reduce the impact
of the collision.

Brake) system
WARNING
QCautions regarding the use of the 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 vehicle 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.
OThe 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 some situations.
OThe 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.
OIt is extremely dangerous to check the system operations by intention-
ally driving the vehicle into the direction of a wall, etc. Never attempt such actions.
QWhen to disable the Parking Sup-port Brake
In the following situations, disable the Parking Support Brake as the system may operate even though there is no
possibility of a collision.
OWhen inspecting the vehicle using
a chassis roller, chassis dynamo or free roller.

3805-5. 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 Support Brake func-
tions (static objects and rear-cross-
ing vehicles) are enabled/disabled
simultaneously. ( P.184)
When the Parking Support Brake is dis-
abled, the PKSB OFF indicator
( P.169) 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 disabled, it will remain
off even if the power switch is turned to
ON after the power switch has been
turned off.
