Replacing fuses
There are relay/fuseboxes located in the engine compartment, the passenger com-partment and the trunk. If an electrical component fails to function, this may be due to a blown fuse. The easiestway to see if a fuse is blown is to remove it. To do so:
1. Pull the fuse straight out. If a fuse is diffi-cult to remove, a special fuse removal
tool is located on the inside of the engine compartment fusebox cover .
2. From the side, examine the curved metal wire in the fuse to see if it is intact.
If the wire is broken, insert a new fuse of the same color and amperage (written on thefuse). If fuses burn out repeatedly, have the electri- cal system inspected by a trained and quali-fied Volvo service technician.
WARNING
Never use metal objects or fuses with higher amperage than those stated on thefollowing pages. Doing so could seriouslydamage or overload the vehicle's electricalsystem.

A .
A decal on the inside of the cover shows thepositions of the fuses. • Fuses 1 – 15, 34 and 42 – 44 are relays/ circuit breakers and should only beremoved or replaced by a trained andqualified Volvo service technician.
• Fuses 16 – 33 and 35 – 41 may bechanged at any time when necessary.
There is a special fuse removal tool on the underside of the cover.
