Store front seat position function

The seat positions for the driver seat and the front passenger seat (with code (242) Electrically adjustable front passenger seat with memory) can be stored using the relevant memory location switch and the memory switch.

The key-specific driver seat position storage (up to 30.5.05) can be activated or deactivated in the instrument cluster. 3 seat positions can be stored for each transmitter key.

There are two ways of saving positions:

1. Press and hold down the relevant memory switch and then also press the relevant location key on the memory location switch.

2. First of all press the memory switch and then release it. Then press the corresponding location key on the memory location switch within t < 3 s.

The current position is stored in the relevant front seat adjustment control unit.

 For vehicles as of 1.6.07 acoustic feedback is provided by the warning buzzer that is integrated in the instrument cluster when the seat position is stored.

When the vehicle is parked, the last setting of the driver seat, outside mirrors and the steering column are stored in a volatile memory.
