Fuses in engine compartment

Fuses in the engine compartment protect engine and brake functions, amongst other things.
P6-XC40-1746-Fuses in engine compartment

The fuse box provides space for several spare fuses.

Positions

Fuse locations are shown on the inside of the cover. Functions and components in the fuse table cover several models and engine alternatives. A fuse description can therefore apply to fewer than those in the table, or be completely missing, depending on how the car is equipped.

If a position has several values in the table, the value depends on variations in equipment level. In which case, follow the value of the fuse being replaced. In the event of doubt – contact a workshop. An authorised Volvo workshop is recommended.
