■When using the Toyota parking
assist-sensor
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 accessories within the sensors’ detection areas.
●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 before.

●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 sen-
sor’s detection areas before the dis- play 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 buzzer if buzzers for other systems are sound-ing.
■Conditions under which the func-
tion may not function correctly
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.
●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.
●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 gravel, 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 producing 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
People may not be detected if they are wearing certain types of clothing.

the vehicle may prevent the sensors from detecting objects correctly or cause the system to not operate or
operate unnecessarily.
■If the Parking Support Brake
function (static objects) oper- ates unnecessarily, such as at a railroad crossing
In the event that the Parking Support Brake function (static objects) oper-ates unnecessarily, such as at a rail-
road crossing, brake control will be canceled after approximately 2 sec-onds, allowing you to proceed forward
and leave the area, brake control can also be canceled by depressing the brake pedal. Depressing the acceler-
ator pedal after brake control is can- celed will allow you to proceed forward and leave the area.
■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 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.
■When to disable the Parking Sup-
port Brake
