The lumbar support consists of two cushions which are inflated by means of a motor for lumbar support. The cushions are inflated or deflated to the required pressure one after the other beginning with the upper cushion. The pressure in the cushions is measured using a pressure sensor (regulating switch). The pressure sensor is located at the same height as the headrest and is integrated into the lumbar adjustment. Automatic adjustment of the lumbar support is carried out by actuating the switch for memory seat adjustment. The motor for lumbar adjustment is shown in Figure 611_98 together with both lumbar cushions. Automatic adjustment of the lumbar support is divided into two phases.

1. If the seat motors have not yet reached their required position, adjustment of the lumbar support is interrupted by releasing the switch for memory seat adjustment.

2. If the seat motors have reached their required position, adjustment of the lumbar support is completed after the switch for memory seat adjustment is released.
