(p. 626) Replacing fuses
All electrical functions and components are pro-
tected by a number of fuses in order to protect
the vehicle's electrical system from damage by
short circuiting or overloading.
1. Refer to the fuse diagram to locate the fuse.
2.

Pull out the fuse and examine it from the
side to determine if the curved metal wire in
the fuse is intact.
3. If the wire is broken, replace the fuse with a new fuse of the same color and amperage.
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
Contact an authorized Volvo workshop for
assistance replacing fuses not listed in the
Owner's Manual. If performed incorrectly, sig-
nificant damage can be caused to the electri-
cal system.
