Engine compartment fuse box
Last of the pre-facelift printings: the 2013 edition adds footnotes to the 2011 tables and moves no number and no rating, so the engine box is again 1 to 47, with the air-injection heater at 15 and the 25 A F/PMP of the 2012 correction. It is mounted on the driver's side of the engine compartment next to the battery and opens by pushing the tab on its lid. Reading the plate: four blades at the top centre, three spares at the top right, DEFOG and SUB BATT as cartridges in the second row, ABS1, ABS2 and ST beside the middle blade group, and the six fusible-link elements filling the lower left.

Instrument panel fuse box
The 2013 edition is the last to print a table for this box, and it repeats the 2011 numbering: twenty-seven positions, nothing on the CIG socket, POWER No.1 as the final cartridge. Reach it from the driver's footwell with the lid off. Two rows of full-size blades, both running left to right, the cartridge among the upper row - an arrangement the facelift keeps even after the tables stop.
