Cases where the parking radar cannot work
properly
The parking radar may not work properly in the
following cases:
1. The sensor is frozen or damp (the sensor can
work normally after being unfrozen or
dehumidified);
2. The sensor is covered by foreign objects such
as heavy rain, snow or water (the sensor can
work normally after the foreign objects are
removed);
3. The vehicle is running on winding roads
(unpaved roads, gravel roads, bumpy roads or
steep slopes);
4. There is interference (vehicle horn, vehicle
engine that makes loud sounds, truck air brake,
air gun sound, etc.) from ultrasonic sources
around the vehicle;
5. There is a radio transmitter within the sensor
detection range.
6. Obstacles are very close to the sensor.
Obstacles that may not be detected by the
radar
The radar may not detect obstacles below:
1. thin sheets or slender objects such as steel
cables, chains, thin posts and piles;
2. objects that can absorb sensor frequencies,
such as snow, clothing or sponge materials;
3. obstacles below the detection range, such as
small animals, short steps or low objects;
4. obstacles above the detection range, such as
hanging objects, rolling gates with lower part
half-open, or truck tail.
