●Certain vehicle conditions and the surrounding environment may affect the ability of a sensor to correctly detect an object.
●Objects may not be detected if they are too close to the sensor.
●There will be a short delay between object detection and display. Even at low speeds, there is a
possibility that the object will come within the sensor’ s detection areas before the display is shown
and the warning beep 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.
●If the meter malfunctions, the buzzer may not sound.
■ 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
projecting outwards in the direction of your vehicle
People may not be detected if they are wearing certain types of clothing.
■ Situations in which the system 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 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 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 ultrasonic 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 detection range.
● When strong winds are 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
