Engine compartment fuse box
Parts catalogues list engine cover 82661-0C300 for 2013 to 2015 production, and that sticker - names and ratings, no numbers - is the source for this box, because the 2015 manual prints no fuse table at all. Numbering follows the last book that had one: the 2013 plate's numbers for the sockets it covered, with 48 (LED DRL), 49 (4WD) and 50 (SHORT PIN) added for the facelift's three extra positions. The carrier is untouched from earlier years - beside the battery on the driver's side, lid on a tab - with the four top blades, the three spares at the top right, DEFOG and SUB BATT below them, and the fusible-link block at the lower left.

Instrument panel fuse box
No interior cover sticker was photographed for 2015, so this box follows the 2016 cover, the nearest facelift record; the manual itself prints nothing. The assignment is the post-facelift one - ECU-IG1 No.3 in the old 4WD socket, ECU-IG1 No.4 as 29 in the formerly empty socket at the lower left, CIG assigned again - laid over the 2010 plate's numbers 1 to 28. It is under the instrument panel on the driver's side, the lid removed from below, the blades in two rows filled from the left with the cartridge among them.
