O If objects draw too close to the sensor.
O When a pedestrian is wearing clothing that does not reflect ultrasonic waves
(ex. skirts with gathers or frills).
O When objects that are not perpendicular to the ground, not perpendicular to
the vehicle traveling direction, uneven, or waving are in the detection range.
O Strong wind is blowing.

flooded road.
O There is dirt, snow, water drops or ice on a sensor. (Cleaning the sensors
will resolve this problem.)
O A sensor is coated with a sheet of spray or heavy rain.
O When driving in inclement weather such as fog, snow or a sandstorm.
O When vehicle horns, vehicle detectors, motorcycle engines, air brakes of
large vehicles, the clearance sonar of ot her vehicles or other devices which
produce ultrasonic waves are near the vehicle.
O If the front of the vehicle is raised or lowered due to the carried load.
O If the orientation of a sensor has been changed due to a collision or other
impact.
O The vehicle is approaching a tall or curved curb.
O Driving close to columns (H-shaped steel beams, etc.) in multi-story parking
garages, construction sites, etc.
O When driving on a narrow road.
