The box outline on this diagram is drawn from photographs of the actual fuse box; ratings and circuit descriptions are verified against the fuse table for this model year. The twenty-two positions sit in two rows of eleven; F1–F11 run along the top row and F12–F22 along the bottom. That order is confirmed on two separate physical panels by matching the fuse ratings visible in the photographs against the factory table — 19 of 22 agree on one, 18 of 19 on the other, while the mirrored order and the right-hand panel both fall to a third of that. The drawing keeps the orientation of the photographed panel; how it is turned once fitted in the car is not shown by any source we have.
