Replacing fuses
If an electrical component fails to function, it is likely that a fuse has blown due to a temporary circuit overload.
The fuse boxes are located in three different places:
A - Relays/fuse box in the engine compartment
B - Fuse box in the passenger compartment
C - Relays/fuse box in the trunk
A label on the inside of each cover indicates the amperage and the electrical components that are connected to each fuse.
The easiest way to see if a fuse is blown is to remove it. Pull the fuse straight out. If a fuse is difficult to remove, you will find a special fuse removal tool in the passenger compartment fuse box. From the side, examine the curved metal wire to see if it is broken. If so, put in a new
fuse of the same color and amperage (written on the fuse). Spare fuses are stored in the fuse box in the passenger compartment. If fuses burn out repeatedly, have the electrical system inspected by an authorized Volvo retailer.
Relays/fuses in the engine compartment
When replacing fuses, be sure to replace a blown fuse with a new one of the same color and amperage (written on the fuse).

Replacing high/low beam headlight bulbs
The headlight bulbs must be replaced from the engine compartment.
CAUTION:
· Do not touch the glass on halogen

bulb and cause damage to the reflector.
· Be sure to use bulbs of the correct
type and voltage.
To remove a defective bulb:
· Switch off the ignition.
· Open the hood.
· Remove the plastic cover over the bulb
(1) by turning it counterclockwise.

first moving it to the right and then moving it down, out of the way.
· Pull out the defective bulb. Note
the position of the guide lug on the base of the bulb (4).
To install a new bulb:

the glass, with the guide lug upward (1). The bulb will only seat properly in
this position.
· Move the retaining spring up and push
it slightly to the left until it seats properly (2).
· Press the connector into place on the
bulb (3).
· Reinstall the plastic cover and turn
it clockwise until it is correctly in place (4). "TOP" must be upward.
NOTE: If the vertical aim of your
headlights needs to be adjusted for any reason
(e.g., towing a trailer for extended periods),
this should be done by an authorized Volvo retailer.
