A buzzer sounds when the sensors are operating.
■When an object is detected to the front or rear of the vehicle
● The buzzer sounds faster as the vehicle approaches an object.
When the vehicle comes within the following distance of the object,
the buzzer beeps continuously.
• Front corner sensor: Approximately 35 cm (1.1 ft.)
• Rear corner sensor: Approximately 40 cm (1.3 ft.)
• Rear center sensor: Approximately 60 cm (2.0 ft.)
● When 2 or more objects are detected simultaneously, the buzzer
system responds to the nearest object.
Approximately 60 cm (24 in.)
Approximately 150 cm (59 in.)
The diagram shows the detection
range of the sensors. Note that the
sensors may not be able to detect
objects that are extremely close to
the vehicle.
The range of the sensors may
change depending on the shape of
the object etc.

■Toyota parking assist-sensor can be operated when
● The engine switch is in the “ON” position (vehicles without smart entry &
start system) or IGNITION ON mode (vehicles with smart entry & start sys-
tem).
● Front corner sensor:
• The shift lever is in other than P.
• The vehicle speed is approximately 10 km/h (6 mph) or less.
● Rear corner and rear center sensors:
The shift lever is in R.
■ Sensor detection information
● The sensor’s detection areas are limited to the areas around the vehicle’s
bumper.
● 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 the objects draw 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.
● 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 the buzzer due to the volume of the audio system
or air flow noise of the air conditioning system.
■ 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
● Moving objects such as people or animals
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 the sensor to correctly detect objects. Particular instances where this
may occur are listed below.
● There is dirt, snow or ice on the sensor. (Wiping the sensors will resolve this
problem.)

● The sensor is frozen. (Thawing the area will resolve this problem.)
In especially cold weather, if a sensor is frozen, the screen may show an
abnormal display, or objects may not be detected.
● The sensor is covered in any way.
● 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 ot her 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.
● 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.
● When a sensor or the area around a
sensor is extremely hot or cold

■ 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 vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of ot her 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.
● When driving on a narrow road.
● When strong winds are blowing.

kit are used.
■ 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 object may not be detected. If the sensor thaws out,
the system should return to normal.
■ If “Parking Assist Malfunction Visit Your Dealer” is displayed on the
multi-information display
Depending on the malfunction of the sensor, the device may not be working
normally. Have the vehicle inspected by any authorized Toyota retailer or
Toyota authorized repairer, or any reliable repairer.
■ If “Parking Assist Malfunction” is displayed on the multi-information dis-
play
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 normal.
■ Customization
Setting of buzzer volume can be changed.
(Customizable features: P. 648)
