Does the XJ have 3 memories for different seat positions for different users, and if so:

1) Does it offer 3 for each, driver and passenger?

2) What settings are tied to these memories? Seat position, exterior mirrors, steering wheel position, seatbelt height position, head rest position? Any other settings that are memorized on each memory bank?

 

1) Yes

2) Seat position, exterior mirrors (driver only), steering wheel position (driver only), headrest position.
