WARNING
QCautions 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.
QTo 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.
ODo not damage the sensors, and always keep them clean.

QThe system can be operated when
OThe power switch is in ON.
OToyota parking assist-sensor function
is on.
OThe vehicle speed is less than about
10 km/h (6 mph).
OThe shift lever is in other than P.
QIf “Clean Parking Assist Sensor” is
displayed on the multi-information 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 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.
QIf “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.
WARNING
ODo 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.
ODo 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.
ODo not modify, disassemble or paint
the sensors.
ODo not attach a license plate cover.
OKeep your tires properly inflated.
QWhen 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.
OFailing to observe the warnings
above.
OA non-genuine Toyota suspension
(lowered suspension, etc.) is installed.
QNotes 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.
OWhen 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.
OWhen using steam to clean the vehicle, do not direct steam too close to the sensors as doing so
may cause a sensor to malfunction.

3745-5. Using the driving support systems
QSensor detection information
OThe sensor’s detection areas are lim-
ited to the areas around the vehicle’s
front and rear bumpers.
OThe 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.
QObjects 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:
OWires, fences, ropes, etc.
OCotton, snow and other materials that
absorb sound waves
OSharply-angled objects
OLow objects
OTall 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.
QSituations 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.
OThere is dirt, snow or ice on a sensor.
(Cleaning the sensors will resolve this
problem.)
OA 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.
OWhen a sensor or the area around a
sensor is extremely hot or cold.
OOn an extremely bumpy road, on an
incline, on gravel, or on grass.
OWhen 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.
OA sensor is coated with a sheet of
spray or heavy rain.
OIf objects draw too close to the sensor.
OWhen a pedestrian is wearing clothing
that does not reflect ultrasonic waves
(ex. skirts with gathers or frills).
OWhen objects that are not perpendicu-
lar to the ground, not perpendicular to
the vehicle traveling direction,
uneven, or waving are in the detection
range.
OStrong wind is blowing.
OWhen driving in inclement weather
such as fog, snow or a sandstorm.
OWhen an object that cannot be
detected is between the vehicle and a
detected object.
OIf an object such as a vehicle, motor-
cycle, bicycle or pedestrian cuts in
front of the vehicle or runs out from
