Planing go abort for around one year, what should i do before i go? how to disconnect the X6s' battery? i really don't wanna call BMW after back. On the maul., it's says need to some reset(s) after re-connected the battery, but its' not say HOW to do the reset...so, can any one tell me how to do the reset after re-connected the battery after i back?

Thank you a lot....:thumbup:
