Rear sensors at the Chevrolet Cobalt must be installed at a height of 45 to 65 cm from the surface. If it is less than 45 cm, the parktronik will regularly show false obstacles, and if above 65 cm., it may not see the real obstacle. All four sensors shall be installed at one height and at the same distance from each other. The distance between the sensors is 45 cm. You can also use the following checksum for ease of installation:

The distance from the centre of the bumper to each of the central sensors is 22.5 cm. Distance from each of the extreme sensors to the edge of the bumper is 22.5 cm.
