Fuses
Replacing fuses
There are relay/fuse boxes located in the engine compartment and the passenger compartment.
If an electrical component fails to function, this may be due to a blown fuse. The easiest way to see if a fuse is blown
is to remove it.
To do so:
1. Pull the fuse straight out. If a fuse is difficult to remove, special fuse removal tools are located on the inside of the
fuse box covers.
2. From the side, examine the curved metal wire in the fuse to see if it is intact.
3. If the wire is broken, insert a new fuse of the same color and amperage (written on the fuse).
If fuses burn out repeatedly, have the electrical system inspected by a trained and qualified Volvo service technician.

WARNING
Never use metal objects or fuses with higher amperage than those stated on the following pages. Doing so could
seriously damage or overload the vehicle's electrical system.

Fuses
Fuse box in the engine compartment
The fuse box in the engine compartment has positions for 36 fuses.
Fuses 1-18 are relays/circuit breakers and should only be removed or replaced by an authorized Volvo service
technician.
Fuses 19-36 may be changed at any time when necessary.
Several extra fuses and a fuse removal tool to assist in removing/replacing fuses can be found on the underside of the
fuse box cover in the engine compartment.

The fuse box in the passenger compartment is located under the glove compartment.
To access the fuses:
1. Remove the upholstery covering the fuse box by first pressing in the center pins in the mounting clips approximately
0.5 in (1cm) with a small screwdriver and then pulling the pins out.
2. Turn both retaining screws (2) counterclockwise until they release.
3. Fold down the fuse box (3) half way. Pull it toward the seat until it stops. Fold it down completely. The fuse box can
be unhooked completely.
4. Replace the blown fuse.
5. Close the fuse box in reverse order.
6. Pull the center pins fully out of the mounting clips, secure the upholstery with the mounting clips and press the pins
into the mounting clips again. The mounting clips then expand, holding the upholstery in position.
