System description
The seat memory is installed in the vehicle as optional equipment in connection with electrically adjustable seats and rearview mirrors. The advantage in comparison with the base version is that there are three memory locations to store the set positions. The stored positions can then be called up at the push of a button. If the vehicle is used by several persons, the seat and mirror positions must only be set once and stored in the system.
