When an obstacle is detected, the buzzer sounds.

As the obstacle is approached, the buzzer sounds more rapidly.
When the obstacle is extremely close, the buzzer switches from
sounding intermittently (short beeps) to continuously (a long beep).

• Distance to obstacle detected by front corner sensor is approxi-

mately 1.2 ft. (35 cm) or less

• Distance to obstacle detected by front side sensor or rear side

sensor is approximately 1.0 ft. (30 cm) or less

• Distance to obstacle detected by front sensor is approximately

1.2 ft. (35 cm) or less

• Distance to obstacle detected by rear corner sensor is approxi-

mately 1.2 ft. (35 cm) or less

• Distance to obstacle detected by back sensor is approximately

1.2 ft. (35 cm) or less

When an obstacle is detected by multiple sensors simultaneously,
the buzzer sounds according to the distance to the closest obsta-
cle.

When obstacles are simultaneously detected to the front and rear
of the vehicle, separate buzzers sound patterns according to the
distance to each obstacle.

The volume and timing of the buzzer can be changed. (

Sensor detection information

The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.

Depending on the shape of the obstacle and other factors, the detection dis-
tance may shorten, or detection may be impossible.

Obstacles may not be detected if they are too close to the sensor.

There will be a short delay between obstacle detection and display. Even
when traveling at a low speed, if you come too close to an obstacle before
the display and buzzer activate, the display and buzzer may not activate at
all.

Thin posts or objects lower than the sensor may not be detected when
approached, even if they have been detected once.

It might be difficult to hear beeps due to the volume of audio system or air
flow noise of the air conditioning system.

Obstacle warning function

When an obstacle in the side areas is within the vehicle course while the
vehicle is moving forward or backward, this function inform the driver by the
display and the buzzer.

Obstacle detection in side areas

Obstacles in the side areas are detected while driving by scanning the side
areas with the side sensors. Recognized obstacles are retained in memory
for up to approximately 2 minutes.

Obstacles may not be detected in the side areas until the scan completes.
After the power switch is turned on, scanning completes after driving the
vehicle for a short period of time.

When an obstacle such as another vehicle, pedestrian or animal is detected
by the side sensors, the obstacle may continue to be detected even after it
has left the side sensor detection area.

If “Clean Parking Assist Sensor” is displayed on the multi-information
display

A sensor may be dirty or covered with snow or ice. In such cases, if it is
removed from the sensor, the system should return to normal.
Also, due to the sensor being frozen at low temperatures, a malfunction dis-
play may appear or an obstacle may not be detected. If the sensor thaws out,
the system should return to normal.

If “Parking Assist Malfunction” is displayed on the multi-information dis-
play

Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by your Toyota dealer.

Certification (Canada only)

This ISM device complies with Canadian ICES-001.

Objects which the system may not properly detect

The shape of the object may prevent the sensor from detecting it. Pay partic-
ular 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 projecting outwards in the direction of your
vehicle

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, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)

A sensor is frozen. (Thawing the area will resolve this problem.) In espe-
cially cold weather, if a sensor is frozen the sensor display may be displayed
abnormally, or objects, such as a wall, may not be detected.

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 clearance sonar of other vehicles or other devices which
produce ultrasonic 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 ultrasonic waves
(ex. skirts with gathers or frills).

When objects that are not perpendicular to the ground, not perpendicular 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

When a sensor or the area around a
sensor is extremely hot or cold.

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 protector (an additional trim strip, etc.), bicycle carrier, 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 possibil-
ity of a collision

In some situations, such as the following, the system may operate even
though there is no possibility of a collision.

When driving toward a banner, flag, low-hanging branch or boom barrier
(such as those used at railroad 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 driving on a narrow road

When strong winds are blowing

WARNING

Cautions regarding the use of the system

There is a limit to the degree of recognition accuracy and control perfor-
mance that this system can provide, do not overly rely on this system. The
driver is always responsible for paying attention to the vehicle’s surround-
ings and driving safely.

To ensure the system can operate properly

Observe the following precautions to avoid an unexpected accident.

Do not damage the sensors, and always keep them clean.

Do not attach a sticker or install an electronic component, such as a backlit
license plate (especially fluorescent type), fog lights, fender pole or wire-
less antenna near a radar sensor.

Do not subject the surrounding area of the sensor to a strong impact. If
subjected to an impact, have the vehicle inspected by your Toyota dealer.
If the front or rear bumper needs to be removed/installed or replaced, con-
tact your Toyota dealer.

Do not modify, disassemble or paint the sensors.

Do not attach a license plate cover.

Keep your tires properly inflated.

When to disable the function

In the following situations, disable the function as it may operate even
though there is no possibility of a collision.

Failing to observe the warnings above.

A non-genuine Toyota suspension (lowered suspension, etc.) is installed.

Side sensors

In the following situations, the intuitive parking assist may not operate nor-
mally and may result in an unexpected accident. Drive carefully.

Obstacles may not be detected in the side areas until the vehicle is driven
for a short time and a scan of the side areas is completed. (

P. 364)

Even after the scan of the side areas is completed, obstacles such as
other vehicles, people or animals that approach from the sides cannot be
detected.

Even after the scan of the side areas is completed, obstacles may not be
detected depending on the surrounding situation of the vehicle.
At that time, the side sensor operation displays (

P. 359) temporary turn

off.

Notes when washing the vehicle

Do not apply intensive bursts of water or steam to the sensor area.
Doing so may result in the sensor malfunctioning.

When using steam to wash the vehicle, do not direct steam too close to
the sensors. The sensors may not function properly if subjected to steam.
