Main fuse box in the driver's footwell (SRB)

The facelift (Mercedes code XM0, on sale from autumn 2013) kept the footwell fuse box exactly where the 2006 van had it: driver's side, left-hand kick panel, one quick-release fastener on the cover. What changed is the engine wiring — fuse 6 now feeds terminal 87 (5), fuse 23 terminal 87 (6), and relay R3 is the terminal 15 starter relay.

Fuses 1–25 are the three columns on the right, each counted from the bottom upwards (1–7, 8–15, 16–24) with the MAXI 25 below the first column; relays R1–R8 sit on the left. Drawn from the MY2015 fuse allocation supplement, the first facelift edition.

Fuse blocks F55/1 and F55/2 on the main fuse box

Fuse blocks F55/1 (1–9) and F55/2 (10–18) hang on the outer end of the main fuse box and restart the count at 1. On facelift vans fuse 6 becomes terminal 87 (1a) and fuse 11 also feeds the navigation cradle; everything else carries over from the pre-facelift table.

Both columns read downwards: 9 at the top of F55/1 down to 1, 18 at the top of F55/2 down to 10.

Fuse box under the driver's seat

The 2013 facelift filled the fifth block of the seat-base fuse box: 37 now protects COLLISION PREVENTION ASSIST and Blind Spot Assist, 38 the multifunction camera, 40 and 41 the auxiliary battery circuits. The box itself is unchanged — outboard side of the driver's seat base, seat fully up, two latching springs, cover off.

Five blocks of nine, all numbered left to right: F55/3 (1–9) and F55/4 (10–18) top, F55/5 (19–27) and F55/6 (28–36) middle, F55/7 (37–45) bottom left. Ratings follow the MY2015 supplement, edition 07-14.
