Narrative:

Location: ord traffic pattern, approach. While on the downwind part of the approach at 6000 ft on flight from detroit. We received a hydraulic system #1, 'low quantity' warning on the MFDU. #1 quantity was 37 pounds. I called approach control and asked for the crash fire rescue equipment trucks to be called out. Then I made a PA to inform the passenger and flight attendants of the situation. We completed the hydraulic system #1 low quantity checklist. My copilot was flying and landed the airplane safely. After landing, we taxied clear of the runway and deplaned all the passenger onto busses. Supplemental information from acn 584640: we were able to taxi clear of runway 9L onto runway 14L, where we deplaned all the passenger and the crew.
