rear windshield wiper fluid

hi, i just find my 2012 x5's rear windshield wiper run out of fluid, while front windshield still have enough fluid

my question is: does x5 has 2 fluid tank, one for front windshield, one for rear windshield? or maybe rear windshield fluid system is blocked somewhere?

thanks

Same tank. Probably a block

Thanks, guys

Seems have to contact dealer
