Function
Driver and front passenger seats are partially electrically adjustable. Manual adjustment is performed using the driver-side partially electric seat adjustment switch (S22/1) on the driver seat and the front passenger partially electric seat adjustment switch (S23/1) on the front passenger seat.

The rear SAM control unit with fuse and relay module (N10/2) supplies the driver-side partially electric seat adjustment switch (S22/1) and front passenger partially electric seat adjustment switch (S23/1) with voltage.
The driver-side partially electric seat adjustment switch (S22/1) actuates the motor for the driver seat height up and down (M25m1) to achieve the desired seat height and backrest motor (M25m2) for the desired driver-side seat backrest inclination.
The front passenger partially electric seat adjustment switch (S23/1) actuates the motor for the seat height up and down (M26m1) to achieve the desired front passenger seat height and the backrest motor (M26m2) for the desired front passenger seat backrest inclination.
