The parking sensor is a device that assists in parking and reversing the car. It works on the principle of sonar - it emits ultrasonic waves, which, after reflection from an obstacle, allow you to determine the distance between the car and the obstacle. When reversing, the device correctly recognizes obstacles in the vehicle's path and warns the driver with a sound.  The new sensors are mounted on the inside of the bumper and do not protrude beyond its outline. Their small size makes them look very attractive. The sensors can be painted. It is recommended to apply a maximum of two thin, even layers of varnish.   The MAX-LED display has a modern design, the upper part of the housing is covered with a glossy black coating (piano black).
