Replacing bulbs09

221 Introduction
Before replacing bulbs in your vehicle, please
keep the following points in mind:
NOTE
Never touch the glass of bulbs with your fin-
gers. Grease and oils from your fingers
vaporize in the heat and will leave a deposit
on the reflector, which will damage it.
The optional Dual Xenon headlight bulbs
contain trace amounts of mercury. These
bulbs should always be disposed of by a
trained and qualified Volvo service techni-
cian.
Certain bulbs should only be replaced by a
trained and qualified Volvo service techni-
cian:
•Courtesylighting
•Reading lights
•Glove compartment lights
•Turn signals and courtesy lights in the
side door mirrors
•High-mounted brake lights
•Dual Xenon headlights, Brake lights
Removing the headlight housing
WARNING
•The engine should not be running when
changing bulbs.
•When changing in the headlight hous-
ing, if the engine has been running just
prior to replacing bulbs, please be
aware that components in the engine
compartment will be hot.
G007334
The entire headlight housing must be lifted out
when replacing the high/low beam, parkinglight, turn signal, and side marker bulbs. To lift
out the housing:
1. Remove the key from the ignition and turn
the headlight switch to position
.
2. Open the hood.
3. Pull up the headlight housing's retaining
pin.
4. Pull out the headlight housing.

5. Disconnect the wiring connector by press-
ing down the clip with your thumb while at
the same time pulling the connector with
your other hand.

09 Maintenance and servicing
Fuses 09
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.

229 Fuse box in the engine compartment
G007446
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.

271 Oil specifications
Engine oil must meet the minimum ILSAC
specification GF-4, API SL, or ACEA A1/B1.
Lower quality oils may not offer the same fuel
economy, engine performance, or engine pro-
tection.
Volume: 6.1 US qts (5.8 liters).
Volume between the MIN and Max marks on
the dipstick: approximately 1.4 US qts (1.3 lit-
ers).
Volvo recommends Castrol.
Depending on your driving habits, premium or
synthetic oils may provide superior fuel econ-
omy and engine protection. Consult your Volvo
retailer or a trained and qualified Volvo service
technician for recommendations on premium
or synthetic oils.
Oil additives must not be used.
NOTE
Synthetic oil is not used when the oil is
changed at the normal service intervals.
This oil is only used at customer request, at
additional charge. Please consult a trained
and qualified Volvo service technician.
Oil viscosityIncorrect viscosity oil can shorten engine life
under normal use. SAE 5W-30 will providegood fuel economy and engine protection. See
the viscosity chart.
G023491
Viscosity chart
Extreme engine operationSynthetic oils meeting SAE 0W-30 or 0W-40
and complying with oil quality requirements are
recommended for driving in areas of sustained
temperature extremes (hot or cold), when tow-
ing a trailer over long distances, and for pro-
longed driving in mountainous areas.
American Petroleum Institute (API)
symbol
G022917
The API Service Symbol "donut" is divided into
three parts:
•The upper section describes the oil's per-
formance level.
•The center identifies the oil's viscosity.
•The lower section indicates whether the oil
has demonstrated energy-conserving
properties in a standard test in comparison
to a reference oil.

Charge air cooler (Intercooler)Turbocharged engines employ a turbo-com-
pressor to force air into the engine inlet mani-
fold and a charge air cooler to cool the com-pressed inlet air. The resulting increase in air
flow raises pressure in the intake manifold and
increases engine power over that developed by
the normally-aspirated engine. The charge aircooler (which resembles a radiator) is located
between the turbo-compressor and inlet mani-
fold.
