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.

2664-5. Using the driving support systems
■If “Parking Assist Unavailable
Please Clean Parking Assist Sen- sor” is displayed on the multi-infor-
mation display
A sensor may be covered with ice, snow, dirt, etc. Remove the ice, snow,
dirt, etc., from the sensor to return the
system to normal.
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.
■Sensor detection information
The following situations may occur dur- ing use.
●The sensors may be able to only detect objects near the front and rear
bumpers.
●Depending on the shape of the object
and other factors, the detection dis-
tance may shorten, or detection may be impossible.
●If an object is extremely close to a sensor, it may not be detected.
●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.
■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 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.
●When a pedestrian is wearing clothing
that does not reflect ultrasonic waves

2764-5. Using the driving support systems
●When a detected vehicle turns while
approaching the vehicle
●When there are spinning objects near
your vehicle such as the fan of an air conditioning unit
●When water is splashed or sprayed toward the rear bumper, such as from
a sprinkler
●Moving objects (flags, exhaust fumes,
large rain droplets or snowflakes, rain
water on the road surface, etc.)
●When the distance between your vehi-
cle and a guardrail, wall, etc., that enters the detection area is short
●Gratings and gutters
●When a sensor or the area around a
sensor is extremely hot or cold
●If the suspension has been modified
or tires of a size other than specified are installed
●If the front of the vehicle is raised or lowered due to the carried load
*: If equipped
■Parking Support Brake func-
tion (static objects) (if
equipped)
Ultrasonic sensors are used to
detect static objects, such as a wall,
in the detection area when driving
at a low speed or backing up.
( P. 2 8 3 )
■Parking Support Brake func-
tion (rear-crossing vehicles) (if
equipped)
Rear radar sensors are used to
detect approaching vehicles in the
PKSB (Parking Suppor t
Brake)*
The Parking Support Brake
system consists of the follow-
ing functions that operate
when driving at a low speed or
backing up, such as when
parking. When the system
determines that a collision with
a detected object is high, a
warning operates to urge the
driver to take evasive action. If
the system determines that the
possibility of a collision with a
detected object is extremely
high, the brakes are automati-
cally applied to help avoid the
collision or help reduce the
impact of the collision.

■If the Parking Support Brake has operated
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. If
the Parking Support Brake operates unnecessarily, brake control can be
canceled by depressing the brake pedal
or waiting for approximately 2 seconds for it to automatically be canceled. Then,
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 ena-
ble the system again ( P.277), or turn
the engine 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 moving forward), the sys-
tem will be re-enabled automatically.
■If “Parking Support Brake Unavaila-
ble” is displayed on the multi-infor- mation display and the PKSB OFF
indicator is flashing
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 ice,
snow, dirt, etc. Remove the ice, snow, dirt, etc., from the sensor to return the
system to normal.
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.
