The Fiat Stilo is a C-segment vehicle produced by the Italian manufacturer from 2001 to 2010. The car premiered at the 2001 Geneva Motor Show. Initially, the model was available only as a hatchback. In 2003, a station wagon variant was introduced, designated as the Stilo MultiWagon. In this article, we provide a detailed overview of the fuse box diagrams for the first-generation Fiat Stilo (body code 192), covering the 2001–2010 model years.
Here you will find the locations and photos of the fuse and relay boxes. The fuses protecting the "cigarette lighter" and "fuel pump" circuits are highlighted in bold.
In the engine compartment
The main fuse box is located next to the battery, beneath a protective cover. Additionally, a primary fuse block containing high-current mega fuses is mounted directly to the positive battery terminal.
