Fuses in engine compartment
Fuses in the engine compartment protect engine and brake functions, amongst other things.
On the inside of the cover there are tweezers that facilitate the procedure for the removal and fitting of fuses.
The fuse box also provides space for several spare fuses.

On the inside of the cover is a label that shows the location of the fuses.
- Fuses 1-13, 18-30, 35-37 and 46-54 are of the "Micro" type.
- Fuses 14-17, 31-34 and 38-45 are of the "MCase" type and should be replaced by a workshop1.
