cian.

228

Replacing fuses

There are relay/fuse boxes located in the
engine compartment and the passenger com-
partment.

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 cov-
ers.

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 follow-
ing pages. Doing so could seriously damage
or overload the vehicle's electrical system.

too high, the quality of the sound may be
impaired.

This can be prevented by adjusting the external
sound source's input volume.

ume to three-quarters using the player's
volume controls.
