■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 pay-ing attention to the vehicle’s sur-
roundings 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 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.
3985-5. Using the driving support systems
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.
■If “Parking Assist Unavailable” is
displayed on the multi-information
display (vehicles with PKSB)
Water may be continuously flowing over
the sensor surface, such as in a heavy
rain. When the system determines that it
is normal, the system will return to nor-
mal.
■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 25 cm (9.8 in.)
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
properly detect
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-
4005-5. Using the driving support systems

vehicle.
●If the front of the vehicle is raised or
lowered due to the carried load.
●If the orientation of a sensor has been
changed due to a collision or other
impact.
●The vehicle is approaching a tall or
curved curb.
●Driving close to columns (H-shaped
steel beams, etc.) in multi-story park-
ing garages, construction sites, etc.
●If the vehicle cannot be driven in a
stable manner, such as when the
vehicle has been in an accident or is
malfunctioning.
●On an extremely bumpy road, on an
incline, on gravel, or on grass.
●When tire chains, a compact spare
tire or an emergency tire puncture
repair kit are used.
■Detection range of the sensors
Approximately 100 cm (3.3 ft.)
Approximately 150 cm (4.9 ft.)
Approximately 60 cm (2.0 ft.)
The diagram shows the detection
range of the sensors. Note that the
sensors cannot detect objects that
are extremely close to the vehicle.
The range of the sensors may
change depending on the shape of
the object, etc.
■Distance display
When an object is detected by a sensor, the approximate distance to the
object will be displayed on the multi-information display or Multimedia Dis-
play. (As the distance to the object becomes short, the distance segments
may blink.)
The images may differ from that shown in the illustrations.
