The reservoir turns out to be under the cover on the driver's side up near the windshield. It requires 3 bolts to be removed, which is a bit of a PITA because of the angle and the amount of space under the hood. Under the cover are the 2 cabin microfilters and the reservoir.
I was unable to get the reservoir filter out without damaging it, but I managed to suck out a bunch of the old fluid with the Motiv pressure bleeder.
BTW, the front bleed valves are larger than the rear. I think the fronts are 11mm while the rear are 9mm, so bring all of your wrenches
