Parking radar system fault alarm description Danger The following situations may result in false alarm or no alarm: ●vehicle horn sound, engine roar, vehicle exhaust, tire inflation and other sounds that near the ultrasonic sensor transceiver band may produce a false alarm. ●when reversing in narrow places or uphill, the system may detect railings, trees or slope surface, which may produce a false alarm. ●car equipped with or near the use of high frequency radio or antenna, may produce a false alarm. rain and snow weather, the sensor surface with ice or dirt may produce no alarm or false alarm.
hot or humid weather, the distance detected may decrease.If there are water droplets attached to the surface of the ultrasonic sensor, the sensitivity will decrease, wipe it off can restore its sensitivity. warning Radar fault warning Obstacles cannot be detected in following situation: ●ultrasonic sensor in the detection of obstacles in the blind area, it can not detect under the bumper, under the car, too close to the car or too far away from the object.
●parking radar system can not detect small wire, cable and block mesh objects, soft snow, cotton, sponge and other easy to absorb ultrasonic objects, rocks, wood blocks, road edge and other low objects, pillars, small trees, bicycles, corner, cornerstone, corrugated paper and other shapes of special objects. ●The surfaces of some objects do not reflect ultrasonic, which cause that these kinds of objects or people wearing such clothing cannot be detected by sensors. Radar system failure When the parking radar system is on, if the fault is detected,instrument cluster will give a sound prompt and display the fault prompt. 162
