No dip stick in an '07 X3. Oil capacity?

[2fast]

I searched the engine compartment looking for an oil dip stick in my new 2007 X3. Not finding it, I read the manual to find out - it doesn't have one! There is an electronic oil level indicator, found by push a button on the instrument panel - inconvenient for an oil change and not too precise. I just pushed it and it says 'ok', not 'on the low side of ok', on the high side, etc.

Also, the manual doesn't give the oil capacity. I guess they assume you'll take it to the dealer for all oil changes and service work. So, does anyone know the oil capacity? Otherwise, I'll drain the used oil into containers of known volume, and hone in on the replacement amount from there.

Thanks.
