| 1. On completely empty car establish a manometre on the air valve and check up that pressure in a control system of a self-levelled back suspension bracket makes 0,8 bar. Otherwise adjust pressure. |
| 2. Establish the car on an equal horizontal platform and measure distance from the centre of a back bumper to the earth. |
| 3. From the measured distance subtract 50 mm and write down the received result. |
| 4. Completely load the car and check up that the car bumper was established at earlier calculated height. |
| 5. If necessary lift pressure in system, but do not exceed it above 5 bar. |
| 6. Completely unload the car and reduce pressure in system to 0,8 bar and check up that the bumper was established on originally measured height. |
| 7. Do not maintain the empty car with a high pressure in a control system self-levelled a back suspension bracket. |
