WARNING
Do not allow oil to spill onto or come into
contact with hot exhaust pipe surfaces
NOTE
Volvo uses different systems to indicate a
low oil level or pressure. Some models have
an oil pressure sensor, in which case a
warning symbol (see page 58) is used to
indicate low oil pressure. Other models have
an oil level sensor, in which case the driver
is alerted by the warning symbol in the cen-
ter of the instrument panel and a text in the
information display. Some models use both
systems. Contact an authorized Volvo
retailer for more information.

221 Washer fluid
Washer fluid reservoir
The washer fluid reservoir is located in the
engine compartment and holds approximately
4.2 US qts (4 liters). During cold weather, the
reservoir should be filled with windshield
washer solvent containing antifreeze.
Coolant
Coolant reservoir
Normally, the coolant does not need to be
changed. If the system must be drained, con-
sult a trained and qualified Volvo service tech-
nician.
CAUTION
•If necessary, top up the cooling system
with Volvo Genuine Coolant/Antifreeze
only (a 50/50 mix of water and anti-
freeze).
•Different types of antifreeze/coolant
may not be mixed.
•If the cooling system is drained, it
should be flushed with clean water or
premixed anti-freeze before it is refilled
with the correct mixture of water/anti-
freeze.
•The cooling system must always be
kept filled to the correct level, and the
level must be between the MIN and
MAX marks. If it is not kept filled, there
can be high local temperatures in the
engine which could result in damage.
Check coolant regularly!
•Do not top up with water only. This
reduces the rust-protective and anti-
freeze qualities of the coolant and has a
lower boiling point. It can also cause
damage to the cooling system if it
should freeze.
•Do not use chlorinated tap water in the
vehicle's cooling system.

WARNING
Never remove the radiator cap while the
engine is warm. Wait until the vehicle cools.
If it is necessary to top off the coolant when
the engine is warm, unscrew the expansion
tank cap slowly so that the overpressure
dissipates.
Brake fluid
Brake fluid reservoir
The brake fluid should always be between the
MIN and MAX marks on the side of the reser-
voir. Check, without removing the cap, that
there is sufficient fluid in the reservoir.Fluid type: DOT 4+ boiling point >536 °F
(>280 °C), P/N 9437433
Replace: The fluid should be replaced accord-
ing to the intervals specified in the Warranty
and Service Records Information booklet.
When driving under extremely hard conditions
(mountain driving, etc), it may be necessary to
replace the fluid more often. Consult your
Volvo retailer. Always entrust brake fluid
changing to a trained and qualified Volvo serv-
ice technician.
WARNING
•If the fluid level is below the MIN mark
in the reservoir or if a brake-related
message is shown in the information
display: DO NOT DRIVE. Have the car
towed to a trained and qualified Volvo
service technician and have the brake
system inspected.
•Dot 4+ should never be mixed with any
other type of brake fluid.
Power steering fluid
The fluid level is checked at each service inter-
val.
Fluid type: Volvo power steering fluid or equiv-
alent.
Replace: No fluid change required.
WARNING
If a problem should occur in the power
steering system or if the vehicle has no elec-
trical current and must be towed, it is still
possible to steer the vehicle. However, keep
in mind that greater effort will be required to
turn the steering wheel.

Replacing bulbs 09
226
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 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.
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
•Active Bending Lights, Brake lights
Removing the headlight housing
WARNING
•The engine should not be running when
changing bulbs.
•If the engine has been running just prior
to replacing bulbs in the headlight hous-
ing, please keep in mind that compo-
nents in the engine compartment will be
hot.
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.

NOTE
The transmission oil does not normally need
to be changed during the service life of the
vehicle. However, it may be necessary to
replace the oil if the vehicle is often driven
in areas of sustained temperature extremes
(hot or cold), when towing a trailer over long
distances, for prolonged driving in moun-
tainous areas, or if the vehicle is often driven
short distances in temperatures under 40 °F
(5 °C).
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 provide
good 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.
