Function prerequisites 

• Driver or passenger door open
• Ignition lock in position I or II

Function 

When one of the power seat switches with memory (S91/2, S92/2) is pressed the corresponding seat is moved to the desired position. Three positions can be stored and recalled with the memory buttons in the power seat switches (S91/2, S92/2).

Function sequence 

The voltage-coded signals from the power seat switches (S91/1, S92/2) are read into the associated door control modules (N69/1, N69/2). The door control modules (N69/1, N69/2) send a CAN message to the associated ESA control module (N32/1, N32/2) which actuates the seat adjustment motors.
