Fuses and fuseboxes
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 possibly lead to a fire.
WARNING
Orange wiring may only be handled by qualified personnel.
WARNING
Several components in the vehicle work with high voltage that can be hazardous in case of an incorrect procedure.
Do not touch anything that is not clearly described in this Owner’s Manual.
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 problem with the component. Volvo recommends contacting an authorized Volvo workshop to have the component checked.
