4-5. Using the driving support systems
Driving
■The system can be operated when
●The engine 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.
WARNING
■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.
●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.

4-5. Using the driving support systems
●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 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

eyelet, bumper protector (an addi- tional trim strip, etc.), 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.
●When driving on a narrow road
●When driving toward a banner, flag, low-hanging branch or boom barrier (such as those used at railroad cross-
ings, toll gates and parking lots)
●When there is a rut or hole in the sur-
face of the road
●When driving on a metal cover (grat-
ing), such as those used for drainage ditches
●When driving up or down a steep slope
●If a sensor is hit by a large amount of water, such as when driving on a flooded road
●There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
●A sensor is coated with a sheet of
spray or heavy rain
●When driving in inclement weather
such as fog, snow or a sandstorm
●When strong winds are blowing
●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
●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.
