Engine compartment fuse box
2017 is the last model year of this box. Toyota's book prints no fuse table, and the parts catalogues list two engine covers for 2017 to 2020 production, 82661-0C310 and 82661-0C320, of which only the 0C320 one - a 2018 assignment - was ever photographed; the 2017 page therefore follows the 2014 facelift sticker, 82661-0C300. Numbering is the 2013 plate's plus 48 LED DRL, 49 4WD and 50 SHORT PIN. The box sits where it has since 2007, on the driver's side of the compartment against the battery, opened by pressing the tab on its lid.

Instrument panel fuse box
For its final model year the box keeps the facelift assignment taken from the 2016 cover sticker: ECU-IG1 No.3 at 16, ECU-IG1 No.4 at 29 in the lower-left socket, CIG at 27 and the POWER No.1 cartridge at 28. Toyota's 2017 manual prints no table to check it against. Lie in the driver's footwell and pull the lid down to reach the two rows of full-size blades, both read from the left; 2018 replaces the whole carrier with a two-column strip.
