WARNING
■Cautions regarding the use of
the system
There is a limit to the degree of recog- nition 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 surroundings and driving safely.
■To ensure the system can oper-ate properly
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 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 fluo-
rescent 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 n ot m od i fy, d is a sse mb l e o r p ai n t 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 colli-
sion.
●Failing to observe the warnings
above.
●A non-genuine Toyota suspension
(lowered suspension, etc.) is installed.
■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.

5-4. Using the driving support systems
Driving
■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.
■Sensor detection information
●The sensor’s detection areas are lim-ited to the areas around the vehicle’s
front and rear bumpers.
●The 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 30 cm 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.
■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 pro- jecting 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 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.
●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 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
●A sensor is coated with a sheet of spray or heavy rain.
●If objects draw too close to the sensor.
WARNING
●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.

■Situations 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.
●When driving on a narrow road
●When driving toward a banner, flag,
low-hanging branch or boom barrier (such as those used at railroad cross-ings, toll gates and parking lots)
●When there is a rut or hole in the sur-face of the road
●When driving on a metal cover (grat-ing), such as those used for drainage
ditches
●When driving up or down a steep
slope

■Buzzer operation and dis-
tance to an object
A buzzer sounds when the sensors
are operating.
 The buzzer beeps faster as the
vehicle approaches an object.
When the vehicle comes within
approximately 30 cm (1.0 ft.) of
the object, the buzzer sounds
continuously.
 When 2 or more sensors simulta-
neously detect a static object,
the buzzer sounds for the near-
est object.
 Even when the sensors are oper-
ating, the buzzer will be muted in
some situations. (automatic

Object
Calculated vehicle route
When the vehicle is moving, the side sensors or side cameras ca n detect
objects. While the vehicle is moving, if a detected object can no longer be
detected by the side sensors or side cameras, the location of t he object rel-
ative to the vehicle is estimated. If the object is determined to be in the esti-
mated path of the vehicle, the object warning function will ope rate.
Object detected by side sensors or side cameras
1 The vehicle is stopped and objects along the sides of the vehicle are not
detected.
2 Objects are detected as the vehicle is moving.
3 Even though the objects are outside of the detection area of the side
sensors or side cameras, a warning is displayed and a buzzer so unds.
■Object warning function operating conditions
●The Advanced Park is operating.
●The vehicle moves about 7 m (23.0 ft.)
after the EV system is started.
●The R shift position is selected.
●After the D shift position has been selected, the vehicle has moved 7 m
(23.0 ft.) or less.
●Camera switch has been pressed and
the multimedia display is displayed.
●The front or rear sensor detects a sta-
tionary object.
■Detection of objects along the sides of the vehicle
●Objects along the sides of the vehicle are not instantaneously detected. The location of objects in relation to the
vehicle is estimated after they are first detected by the front or rear side sen-sors, or side cameras. Therefore, after
