■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’ 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 emoved/installed or replaced,
contact 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.

Object
Calculated vehicle course
■Object detection in side areas (if equipped)
●Objects in the side areas are detected while driving by scanning the side
areas with the side sensors. Recog-
nized objects are retained in memory for up to approximately 2 minutes.
●Objects may not be detected in the side areas until the scan completes.
After the engine switch is turned on,
scanning completes after driving the vehicle for a short period of time.
●When an object such as another vehi-cle, pedestrian or animal is detected
by the side sensors, the object may
continue to be detected even after it has left the side sensor detection
area.
■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.
■If “Parking Assist Unavailable” is
displayed on the multi-information display
●Water may be continuously flowing
over the sensor surface, such as in a heavy rain. When the system deter-
mines that it is normal, the system will
return to normal.
●Initialization may not have been per-
formed after a battery terminal was disconnected and reconnected. Initial-
ize the system. ( P.306)
If this message continues to be dis- played even after initialization, have
the vehicle inspected by any author-
ized Toyota retailer or Toyota author- ized repairer, or any reliable repairer.
■If a battery terminal has been dis-
connected and reconnected
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.
■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
307

4-5. Using the driving support systems
Driving
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.
●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.
●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
(ex. skirts with ga thers or frills).
●When objects that are not perpendicu-
lar to the ground, not perpendicular to
the vehicle traveling direction, une- ven, 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, et c.), 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 a tire chains, compact spare tire or an emergency tire puncture repair
kit is used
■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.
