Memory buttons
WARNING: This page is about a different car, the 2001 Saab 9-3. However, it is still accessible from the selected car via links, so may be relevant.
The switch for the memory and memory store function comprises four buttons; three memory buttons, "1", "2" and "3", and a memory store button "M".
When settings are being stored in memory, the control module reads all Hall sensors and stores their values in an internal seat memory. The seat memory is non-volatile and retains the data even when the control module power is turned off.
