Objects which the system may not be properly detected
The shape of the object may prevent the sensor from detecting it. Pay partic-
ular 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 projecting outwards in the dir ection of your
vehicle
■ Situations in which the syst em may not operate properly
Certain vehicle conditions and the surrounding 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 t he area will resolve this problem .)
In especially cold weather, if a sensor is frozen the sensor di splay may be
displayed abnormally, or objects, such as a wall, may not be detected.
● On an extremely bumpy road, on an incline, on gravel, or on grass.
● When vehicle horns, vehicle detectors, 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 ult rasonic waves
(ex. skirts with gathers or frills).
● When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the d etection range.
● Strong wind is blowing
● When driving in inclement weather such as fog, snow or a sandst orm
● When an object that cannot be detected is between the vehicle a nd a
detected object
● If an object such as a vehicle, motorcycle, bicycle or pedestrian cuts in front
of the vehicle or runs out from the side of the vehicle
●
When a sensor or the area around a
sensor is extremely hot or cold.
