Turning Toyota parking
assist-sensor on/off
The Toyota parking assist-sensor
function can be enabled/disabled
through a customize setting.
When the Toyota parking assist-sensor
function is disabled, the Toyota parking assist-sensor OFF
indicator illuminates on the
multi-information display.
If the system switches to OFF (disabled)
and the Toyota parking
assist-sensor is stopped, the
Toyota parking assist-sensor will
not be re-enabled until ON
(enabled) is selected again from
the customize setting.
(It remains off even if the power
switch is turned to ON again after
the power switch has been turned
off.)
Vehicles without the multimedia display
or rear camera: However, the
system will automatically turn on
(enabled) and the Toyota parking
assist-sensor OFF indicator will
turn off if the shift position is
changed to R.
When the shift position is R, the
Toyota parking assist-sensor cannot
be turned on or off.
The setting of Toyota parking
assist-sensor itself will not change.
WARNING
■Cautions regarding the use of
the system
There is a limit to the degree of recognition
accuracy and control performance
that this system can provide,
do not overly rely on this system. The
driver is always responsible for paying
attention to the vehicle's surroundings
and driving safely.
■To ensure the system can operate
properly
Make sure to observe the following
precautions. The system may not
operate properly and may lead to an
unexpected accident. When these
precautions cannot be observed, turn
the system off.
- 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 wireless 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 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.
- Do not modify, disassemble or paint
the sensors.
- Do not attach a license plate cover.
- Keep your tires properly inflated.
- Do not install a suspension other
than a genuine suspension.
■Notes when washing the vehicle
- When using a high pressure
washer to wash the vehicle, do not
spray the sensors directly, as doing
so may cause a sensor to malfunction.
- 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.
■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).
- A shift position other than P is
selected.
Vehicles without the multimedia display
or rear camera: The system will automatically
turn on (enabled) and the
Toyota parking assist-sensor OFF indicator
will turn off if the shift position is
changed to R.
The setting of Toyota parking assist-sensor
itself will not change.
■Sensor detection information
- The sensor's detection areas are limited
to the areas around the vehicle's
front and rear bumpers.
- Certain vehicle conditions and the surrounding
environment may affect the
ability of a sensor to correctly detect
an object.
- Objects may not be detected if they
are too close to the sensor.
- There will be a short delay between
object detection and display.
Even at low speeds, there is a possibility
that the object will come within the sensor's
detection areas before the display
is shown and the warning beep 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.
- If the meter malfunctions, the buzzer
may not sound.
■Objects which the system 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 projecting
outwards in the direction of
your vehicle
People may not be detected if they are
wearing certain types of clothing.
■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 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.
- 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 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.
- When strong winds are 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 such as a towing
eyelet, transport hook, bumper protector,
bumper trim, bicycle carrier or
snow-removal device (snow plow) is
installed near the sensor
- 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, compact spare tire
or an emergency tire puncture repair
kit are used
- When towing with the vehicle
■Situations in which the system may
operate even if there is no possibility
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 on a narrow road

- 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 strong winds are blowing

- 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
- If the front of the vehicle 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, construction 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, compact spare tire
or an emergency tire puncture repair
kit are used
- When towing with the vehicle
