Fuses in the engine compartment
The fuses in the engine compartment help protect electrical components such as engine and brake functions.
Fuse pliers are provided on the inside of the fuse box cover to assist in removing and inserting fuses.
There are also spaces for several extra fuses in the fusebox.
Positions
There is a decal with a diagram of the locations of the fuses on the inside of the cover.
- Fuses 1-13, 18-30, 35-37 and 46-54 are "Micro" fuses.
- Fuses 14-17, 31-34 and 38-45 are "MCase" fuses and should only be replaced by a workshop1.
