11. ven if you have applied brake your vehicle will still go for some distance inertia before it comes to a complete stop Because the back up parking system detects obstacle by emitting ultrasonic wave and receiving reflected ultrasonic wave from obstacle the system may fail to give both visual and audible alert if an obstacle has smooth ball shaped or sloped surfaces as such surfaces may not reflect ultrasonic wave back to the sensors Drivers in these situations should pay more attention while parking their vehicles in heavy falling rain or snow the system may give alert as falling rain or snow may be detected as obstacles Keep surface of sensors clean of snow mud dirt and other debris Troubleshooting Problem Cause Solution Display doesn t light up when reversing or forwarding with braking No power to the display No power to the main control box Faulty display Check display power connection Check main control box power connection Replace the display Contact Technical Support for help Display light up but system is not detecting any obstacle Sensors not connected Faulty display Faulty main control box Check sensor connections Replace the display Replace the main control box Contact Technical Support for help System showing distance but no beeping or system beeping but no distance display System is not detecting any obstacle in front System is not detecting any obs
