Automatic Adjustment of Driving Position

Function requirements
The automatic adjustment to the driving position of the steering column and the exterior rearview mirror is activated under the following state transitions:
- No circuit after 15c (regardless of the state of the driver's door)
- Circuit 15c after circuit 15R (regardless of the state of the driver's door)
- Circuit 15R after circuit 15 (regardless of the state of the driver's door)
- Driver's door open after driver's door closed (with ignition key at circuit 15)

Function
When the vehicle is entered, the driver's seat, steering column and mirrors are adjusted to the last driving position. The last set driving position depends on the current memory block number.


NOTE: The memory block number denotes the key-specific data record entered in the EIS [EZ5].


This operation is controlled by the driver front seat adjustment control module with memory (N32/1) located on the driver's side. Movement into the driving position is triggered by the above listed changes in the ignition key position and door contact states.

Abort conditions
All abort conditions are monitored by the driver front seat adjustment control module with memory (N32/1).
Adjustment to the driving position is not reactivated when the input signal that caused the abort returns to its initial state. This applies to all abort conditions. Only when the activation conditions are satisfied again is adjustment to the driving position reactivated.


Adjustment to the driving position is aborted in the following cases:
When the driver presses any of the buttons on the driver-side power seat switch (memory) (S91/12).
Where adjustment to the driving position is aborted by the driver. the abort is canceled when the following state transitions are present:
- Circuit 15c after no circuit
- Circuit 15 after circuit 15R

Abort due to contrary state transitions
Adjustment into the driving position is aborted by the driver front seat adjustment control module with memory (N32/1) when the following ignition key position and door contact state transitions, which are contrary to the activation conditions, occur:
- Circuit 15 after circuit 15R
- Circuit 15R after circuit 15c
- Circuit 15c after no circuit
- Driver's door open after driver's door closed with circuit 15 OFF

Repeat limiter
Alternately inserting and removing the ignition key causes repeated back and forth movement between the easy entry/exit and driving positions (with door open: steering column only; with door closed: seat and steering column). To prevent this, the number of cycles is limited to 5. The counter is reset when:
- The ignition key is turned to circuit 15R, or
- The status of the driver door is changed
