Fuses
The fuses help protect the vehicle's electrical
components from overloading or short circuits.
WARNING
Never use metal objects or fuses with higher
amperage than those stated on the lists of
fuses. Doing so could seriously damage or
overload the vehicle's electrical system.
Orange wires may only be handled by trained
and authorized Volvo service technicians or
licensed electricians.
A number of component in the vehicle used
high voltage electrical current and can be very
dangerous to touch.
Do not touch any components that are not
clearly described in this owner's information.
If an electrical component fails to function, this
may be due to a blown fuse. If the same fuse
blows repeatedly, this indicates a problem with
the component, which should be inspected by a
trained and qualified Volvo service technician.

Replacing fuses
The fuses help protect the vehicle's electrical
components from overloading or short circuits.
Fuse replacement
1. See the list of fuse boxes for their locations.
2. Pull the fuse straight out and examine it from
the side to see if the curved metal wire in the
fuse is intact.
3. If the wire is broken, insert a new fuse of the
same color and amperage (written on the
fuse).
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.

Replacing bulbs
The halogen headlight bulbs
3
can be replaced
by the owner.
Before the halogen headlight bulbs can be
replaced, that plastic covering over the headlight
housing has to be removed.
Halogen headlights are not available on all
models or in all markets.
Consult your Volvo retailer if you are uncertain
about the type of headlights in your vehicle.
To do so:
Lift the rubber strip by pressing in toward the
engine compartment.
Release the pins in the plastic covering's
four clips by pressing them down with a
screwdriver or similar object and remove the
covering.
The turn signal, high/low beam, Daytime Running
Light and parking light bulbs will be accessible
when the plastic covering has been removed.
Put the covering back in place in the reverse
order.
The pins in the clips have to be pressed back
completely before the clips are placed in the
plastic covering.
When the covering is put back in place, the
pins must be pressed so that their upper sur-
face is flush with the surface of the clip.

Halogen headlights are not available on all models.

•
For information regarding any bulbs not
mentioned in this section, please contact
your Volvo retailer or a trained and
authorized Volvo service technician.
•
Always switch off the ignition before star-
ting to replace a bulb.
•
If an error message remains in the dis-
play after a faulty bulb has been replaced,
contact an authorized Volvo workshop.
•
Condensation may form temporarily on
the inside of the lenses of exterior lights
such as headlights, fog lights, or taillights.
This is normal and the lights are
designed to withstand moisture. Normally,
condensation will dissipate after the
lights have been on for a short time.
•
The optional Active Bending Light bulbs
contain trace amounts of mercury. These
bulbs should always be disposed of by a
trained and qualified Volvo service techni-
cian.
Never touch the glass of bulbs with your fin-
gers. Grease and oils from your fingers vapor-
ize in the heat and will leave a deposit on the
reflector, which will damage it.
WARNING
•
The ignition should be switched off com-
pletely (be in ignition mode 0) when
replacing bulbs.
•
If the engine has been running just prior
to replacing bulbs in the headlight hous-
ing, please keep in mind that components
in the engine compartment will be hot.

1. Loosen the cover's four screws with a T20
Torx screwdriver (1) but do not remove them
completely (turning them 3–4 turns is
enough).
2. Push the cover to the side.

Replacing low beam headlight bulbs
On models with halogen headlights, the low
beam headlight bulb can be replaced by the
owner.
Before the bulb can be replaced, the plastic cov-
ering over the headlight housing has to be
removed, see the article "Replacing bulbs."
Never touch the glass of bulbs with your fin-
gers. Grease and oils from your fingers vapor-
ize in the heat and will leave a deposit on the
reflector, which will damage it.
Driver's side bulb housing shown
1. Remove the low beam round rubber cover
from the headlight housing.
2. Remove the connector from the bulb.
3. Remove the bulb by pressing it slightly
upward and then pulling it out.
4. Insert the bulb in the socket. The bulb's guid-
ing pin should point straight up.
5. Press the connector into place.
6. Put the rubber cover back into place.
