Fuses The fuses help protect the vehicle's electrical components from overloading or short circuits.
WARNING
Never use metal objects or fuses with higher amperage than those stated on the lists offuses. Doing so could seriously damage oroverload the vehicle's electrical system. Orange wires may only be handled by trained and authorized Volvo service technicians orlicensed electricians. A number of component in the vehicle used high voltage electrical current and can be verydangerous to touch. Do not touch any components that are not clearly described in this owner's information.
If an electrical component fails to function, this may be due to a blown fuse. If the same fuseblows repeatedly, this indicates a problem withthe component, which should be inspected by atrained and qualified Volvo service technician.
