F3x (maybe F10?) It resets the Intelligent Battery System so that it can optimize charging/discharge rates as the battery ages, in an attempt to lengthen battery life . The new cars use a lot of juice. BMW and others abandoned their attempt to use dual-voltage systems (one 12v, one 42v ? IIRC) and this is the result.
