Dashboard fuse box

Citroën issued handbook edition ed01-11 for cars built from 15 September 2011, and it is the edition that applies here. It rewords three positions in this box: F9 now also feeds the central locking, F8 picks up the after-market audio and portable navigation carrier, and F7 adds the glove box lamp to the courtesy and reading lamps. F1 is still the 15 A rear wiper fuse, as it will be for one more model year.

The box is in the lower part of the dashboard on the left-hand side, or behind the glove box lid on a right-hand-drive car. Unclip the cover by pulling on its side; the tweezer and spare fuses are carried on its back. Fourteen MINI fuses run in one row along the lower edge of the built-in systems interface, ordered F1, F13, F12, F6, F5, F9, F3, F4, F11, F8, F10, F7, F14, F15 from the left, with the PARC shunt SH beneath the centre of the row and the 40 A MAXI F17 beneath its right-hand end. F2 and F16 are listed as not used and have no socket.

Engine compartment fuse box

Open the bonnet and look to the left, beside the battery: the engine relay unit is the box with the clip-on lid. Unclip it to get in and press it back down so the housing reseals.

Seen from above, connectors at the top, the plate reads like this. Upper row, seven MINI fuses, left to right: F20, F19, F21, F15, F16, F18, F17 — the plate staggers their labels above and below the row. Left-hand side: the 30 A MAXI F10 standing below F20, and the 40 A MAXI F11 lying at the bottom corner. Middle: a round connector, with the lower row of five MINI fuses F1, F3, F2, F4, F8 running left to right beneath it. Right-hand side: the 40 A MAXI F13 lying beside the connector, a two-by-two MINI block with F9 and F5 on top of F7 and F6, and the pair of 30 A MAXI fuses F14 over F12 at the edge. Handbook edition ed01-11 applies to a 2012 car and changes nothing in this box. MF1 to MF8, the maxi-fuses, are on a separate holder for the dealer.
