Abnormalities of the reversing radar system
Be aware that in the following cases the reversing radar system may not give an
alarm:
1. The reversing radar sensor cannot detect networks, such as iron wires, cables, and
nets.
2. The reversing radar sensor cannot detect low objects such as rocks and wood blocks.
3. The reversing radar sensor cannot detect a vehicle with a high chassis.
4. The reversing radar sensor cannot detect objects which absorb ultrasonic waves easily,
such as soft snow, cotton, and sponges.
5. The reversing radar sensor may not detect some obstacles of special shapes (such as
Warning
● When the distance from the obstacles is smaller than 0.35m, the alarm sound will
be constant. At this moment, immediately stop reversing.

Be aware that in the following cases the
reversing radar system may give a false
alarm:
1. When the surface of the reversing radar
sensor is frozen, the reversing radar
system may generate false alarms.
2. When the vehicle is on a steep slope,
the reversing radar system may generate
false alarms.
3. When a high-frequency radio or antenna
is installed on the vehicle or used in a
nearby place, reversing radar system
may generate false alarms.
4. If the horn sound, engine roar, emission
sound, and other sounds of other
vehicles are too close to the reversing
radar sensor, the reversing radar system
may generate false alarms.
5. When you are driving in snowy or rainy
weather, the reversing radar system may
generate false alarms.
When you have conrmed that the above
conditions do not exist, please contact
the after-sales service store for check and
repair.
