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 a sticker or an electronic component, such as a backlit
license plate (especially fluorescent type), fog lights, fender pole or wire-less antenna is installed near a
radar sensor.

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).
●The shift lever is in other than P.
■If “Clean Parking Assist Sensor” is
displayed on the multi-information display
A sensor may be covered with water
drops, ice, snow, dirt, etc. Remove the water drops, ice, snow, dirt, etc., from the sensor to return the system to nor-
mal.
Also, due to ice forming on a sensor at low temperatures, a warning message
may be displayed or the sensor may not be able to detect an object. Once the ice melts, the system will return to normal.
If a warning message is displayed even if the sensor is clean, there may be a sensor malfunction. Have the vehicle
inspected by any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
■Sensor detection information
●The sensor’s detection areas are lim-ited to the areas around the vehicle’
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
WARNING
●Do not subject the radar sensor or its surrounding area to a strong
impact. If the radar sensor, front grille, or front bumper has been subjected to a strong impact, have
the vehicle inspected by any autho- rized Toyota retailer or Toyota authorized repairer, or any reliable
repairer. If a sensor or the rear bumper needs to be removed/installed or replaced, con-
tact 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.
■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.
●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.

static object detection and display
(warning buzzer sounds). Even at low speeds, there is a possibility that the object will come within 30 cm (1.0 ft.)
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
■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.
●Pedestrians that are hard to reflect
ultrasonic waves (ex. skirts with gath- ers or frills).
●When objects that are not perpendicu-lar 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, motor-cycle, 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 addi-
tional trim strip, etc.), bicycle carrier, or snow plow

the vehicle can be operated by depress- ing the accelerator pedal.
■Re-enabling the Parking Support Brake
To re-enable the Parking Support Brake when it is disabled due to operation of the Parking Support Brake, either
enable the system again ( P.266), or turn the power switch off and then back to ON. Additionally, if the object
becomes no longer in the traveling direction of the vehicle or if the traveling direction of the vehicle changes (such
as changing from moving forward to backing up, or from backing up to mov-ing forward), the system will be re-
enabled automatically.
■If “PKSB Unavailable” is displayed on the multi-information display and the PKSB OFF indicator is on
If the vehicle is stopped due to operation of the Parking Support Brake, the Park-ing Support Brake will be disabled and
the PKSB OFF indicator will illuminate.
●A sensor may be covered with water
drops, ice, snow, dirt, etc. Remove the water drops, ice, snow, dirt, etc., from the sensor to return the system to nor-
mal. Also, due to ice forming on a sensor at low temperatures, a warning message
may be displayed or the sensor may not be able to detect an object. Once the ice melts, the system will return to
normal.
●If this message is displayed, a sensor
on the front or rear bumper may be dirty. Clean the sensors and their sur-rounding area on the bumpers.
●If this message continues to be dis-played even after cleaning the sensor,
or is displayed even though the sen- sor is clean, have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer.
■If a 12-volt battery terminal has
been disconnected and recon- nected
The system needs to be initialized. To
initialize the system, drive the vehicle straight ahead for 5 seconds or more at a speed of approximately 35 km/h (22
mph) or more.

■The Parking Support Brake func- tion (static object) will operate
when
The function will operate when the PKSB OFF indicator is not illuminated or
flashing ( P.91, 92) and all of the fol- lowing conditions are met:
●Hybrid system output restriction con-trol• The Parking Support Brake is
enabled. • The vehicle speed is approximately 15 km/h (9 mph) or less.
• There is a static object in the traveling direction of the vehicle and approxi-mately 2 to 4 m (6 to 13 ft.) away.
• The Parking Support Brake deter- mines that a stronger-than-normal brake operation is necessary to avoid
a collision.
●Brake control
• Hybrid system output restriction con- trol is operating.• The Parking Support Brake deter-
mines that an immediate brake opera- tion is necessary to avoid a collision.
■The Parking Support Brake func-tion (static objects) will stop oper-
ating when
The function will stop operating if any of the following conditions are met:
●Hybrid system output restriction con-
trol • The Parking Support Brake is dis-abled.
• The system determines that the colli- sion has become avoidable with nor-mal brake operation.
• The static object is no longer approxi- mately 2 to 4 m (6 to 13 ft.) away from the vehicle or in the traveling direction
of the vehicle.
●Brake control
• The Parking Support Brake is dis- abled.• Approximately 2 seconds have
elapsed since the vehicle was stopped by brake control.• The brake pedal is depressed after
the vehicle is stopped by brake con-
trol. • The static object is no longer approxi-mately 2 to 4 m (6 to 13 ft.) away from
the vehicle or in the traveling direction of the vehicle.
■Re-enabling the Parking Support Brake function (static objects)

■Detection range of the Parking Sup- port Brake function (static objects)
The detection range of the Parking Sup-
port Brake function (static objects) dif- fers from the detection range of the Toyota parking assist-sensor. ( P.258)
Therefore, even if the Toyota parking assist-sensor detects an object and pro-vides a warning, the Parking Support
Brake function (static objects) may not start operating.
■Objects which the system may not be properly detected

■Toyota parking assist-sensor buzzer
Regardless of whether the Toyota park-
ing assist-sensor buzzer is enabled or not ( P.254), if the Parking Support Brake function (static objects) is enabled
( P.266), the front or rear sensors detect an object and brake control is performed, the Toyota parking assist-
sensor buzzer will sound to notify the driver of the approximate distance to the object.
