Mercury Milan and Milan Hybrid 2010-2011 use a passenger-compartment fuse panel and an engine-compartment Power Distribution Box. Hybrid models have a substantially different under-hood layout and an additional relay box, so their circuits are shown separately.
For the earlier version, see Mercury Milan 2006-2009.

FAQ – Mercury Milan 2010-2011 fuses
Can I use the gasoline fuse table for a Milan Hybrid?
No. The Hybrid has a different under-hood power distribution layout and an additional relay box for headlamps, blower, PCM and vacuum-pump circuits.
Where is the OBD-II fuse?
Passenger-compartment position 20 – 15 A.
