Fuses and fuse boxes
All electrical functions and components are protected by a number of fuses in order to protect the vehicle’s electrical system from damage by short circuiting or overloading.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified to replace a fuse. This could cause significant damage to the electrical system and possi-bly lead to a fire.
If any electrical component or function is not responding, the component may have blown a fuse due to temporary overload. If the same fuse blows repeatedly, there may be a prob-lem with the component. Volvo recommends contacting an authorized Volvo workshop to have the component checked.
Location of fuseboxes
The illustration is generic – appearance may vary according to vehicle model.
- Engine compartment
- Under the glove compartment
- Trunk/cargo compartment
All electrical functions and components are protected by a number of fuses in order to protect the vehicle’s electrical system from damage by short circuiting or overloading.
-
Refer to the fuse diagram to locate the fuse.
-
Pull out the fuse and examine it from the side to determine if the curved metal wire in the fuse is intact.
-
If the wire is broken, replace the fuse with a new fuse of the same color and amper-age.
WARNING
Never use a foreign object or a fuse with a higher amperage than that specified to replace a fuse. This could cause significant damage to the electrical system and possi-bly lead to a fire. Contact an authorized Volvo workshop for assistance replacing fuses not listed in the Owner’s Manual. If fuse replacement is performed incorrectly, significant damage can be caused to the electrical system.
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 loca-tions of the fuses on the inside of the cover.
