Under the following conditions, the detection function may not function properly:
The sensor is covered with foreign matter, such as mud or snow (detection function returns to normal when sensor is cleaned).
The sensor is frozen (detection function returns to normal when the temperature of the sensor rises).
A hand is blocking the sensor.
- HINT:
The detection range may be affected by the following conditions:
The sensor is covered with foreign matter, such as mud or snow.
The vehicle is in an excessively not or excessively cold area.
Under the following conditions, a detection error may occur:
Driving on a bumpy road, an unpaved road, or in tall grass.
Ultrasonic waves from items such as another vehicle's horn, motorcycle engine sounds, a large vehicle's air brake sound, or another vehicle's sonar are transmitted near the vehicle.
It is raining heavily or the sensor comes into contact with water (sprayed).
The vehicle is tilted at a long angle.
The vehicle is equipped with a commercial fender pole or a wireless mechanism antenna.
The sensor is covered with foreign matter, such as mud or snow.
The vehicle is moved forward or backward towards high curbs or objects that are perpendicular to the ground.
The sensor cannot detect the following objects:
Thin objects, such as wires and ropes.
Materials that absorb ultrasonic waves, such as cotton, snow, etc.
Objects with sharp edges.
Short objects.
Objects with a part that projects upward a large distance.
Other objects.
Other notices:
The sensor cannot detect objects directly under the bumper. (The sensor may detect low objects and thin poles, and then lose track of the objects.)
The sensor may not be able to detect obstacles that are too close to the sensor.
The sensor may not be able to detect obstacles if it is dropped or subjected to a strong impact.
