Fuses in the engine compartment

The fuses in the engine compartment help protect electrical components such as engine and brake functions.
P6-XC40-1746-Fuses in engine compartment

There are spaces for several extra fuses in the fuse box.

Positions

The location of the fuses is shown on the inside of the cover. Functions and components in the fuse table cover several different models and engine variants. Therefore, a described fuse may apply to fewer components than those in the table, or be missing completely, depending on how the vehicle is equipped.

If a position has several values in the table, the value depends on variations in equipment level. If this is the case, follow the value on the replaced fuse. In the event of uncertainty, contact a workshop. An authorized Volvo workshop is recommended.
