Engine compartment fuse box
No 2016 engine cover photograph turned up and the parts catalogues show no separate 2016 sticker, so this box is read from the 82661-0C300 cover of the 2014 facelift; the 2016 manual, like every book after 2013, prints no table. The numbers combine the 2013 plate's with 48, 49 and 50 for LED DRL, 4WD and the SHORT PIN. Open it as always - driver's side of the engine bay, next to the battery, push the lid tab in and lift the lid off. The plate arrangement of four blades on top, spares at the top right, cartridges in the second row and links at the lower left has not moved since 2007.

Instrument panel fuse box
The photograph that establishes the facelift interior assignment is of a 2016 cover, corroborated by a picture of an open 2016 box showing a 7.5 A fuse where 4WD's 20 A used to sit. Names and ratings therefore come from that sticker, and the numbers are the 2010 plate's, with 29 for the ECU-IG1 No.4 socket at the lower left. The carrier is under the driver's side of the instrument panel, worked on from the footwell with the lid off, and holds two rows of full-size blades plus the POWER No.1 cartridge.
