G030881
CAUTION
Not checking the oil level regularly can result
in serious engine damage if the oil level
becomes too low.•
Never fill oil above the MAXmark. This
could cause an increase in oil consump-
tion.
•
Not checking the oil level regularly can
result in serious engine damage if the oil
level becomes too low.
•
Always add oil of the same type and
viscosity as already used.
WARNING
Do not allow oil to spill onto or come into
contact with hot exhaust pipe surfaces.

09 Maintenance and servicing
Fluids
09``211 Washer fluid reservoir
G027097
Washer fluid reservoirThe washer fluid reservoir is located in the
engine compartment and holds approx.
6.8 US qts (6.5 liters).
When there is less than approximately 1 US qt
(1 liter) remaining in the reservoir, the washer
fluid spray will be directed to the windshield
only.
During cold weather, the reservoir should be
filled with windshield washer solvent contain-
ing antifreeze.
Changing coolant
G027087
Coolant reservoirNormally, 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
vehicles cooling system.

09 Maintenance and servicingFluids
09212
WARNING
•
Never remove the radiator cap while the
engine is warm. Wait until the vehicle
cools.
•
If it is necessary to top up the coolant
when the engine is warm, unscrew the
expansion tank cap slowly so that the
overpressure dissipates.
Brake fluid reservoir
G000000
The brake fluid should always be above the
MIN mark on the side of the reservoir. Check,
without removing the cap, that there is suffi-
cient fluid in the reservoir.Fluid type: DOT 4+ boiling point >536 °F
(280 °C), P/N 9437433.
Replace: Every second year or 30,000 miles
(48,000 km). The fluid should be replaced once
a year or every 15,000 miles (24,000 km) when
driving under extremely hard conditions
(mountain driving, etc.).
Always entrust brake fluid changing to a
trained and qualified Volvo service technician.
Power steering fluid reservoir
FULL
ADD
G026991
The fluid level should always be between the
ADD and FULL marks.Fluid type: Volvo synthetic power steering fluid
(Pentosin CHF 11S) P/N 1161529 or equiva-
lent.
Replace: No fluid change required.
If a problem should occur in the power steering
system or if the vehicle has no electrical 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.

Battery maintenance
A
G030882
Two types of battery may be used and are fully
interchangeableThe battery in your vehicle is located under the
floor of the cargo compartment.
Driving habits and conditions, climate, the
number of starts, etc. all affect the service life
and function of the battery. In order for your
battery to perform satisfactorily, keep the fol-
lowing in mind:
G030883
•
Check the fluid level in each cell in the bat-
tery every 24 months or every 15,000
1
miles (24,000 km), whichever is sooner.
The fluid should be at the level shown in the
illustration above (A)
2. Do not overfill.
•
Use a screw driver to open the caps or
cover and a flashlight to inspect the level.
•
If necessary, add distilled water. The level
should never be above the indicator (A)
2.
•
The fluid level should be checked if the
battery has been recharged.
•
After inspection, be sure the cap over each
battery cell or cover is securely in place.
•
Check that the battery cables are correctly
connected and properly tightened. Route
ventilation hose through opening in floor
(see one of the illustrations in "Replacing
the battery" on page 215).
•
Never disconnect the battery when the
engine is running, for example when
changing the battery.
•
The battery should be disconnected from
the vehicle when a battery charger is used
directly on the battery.
•
However, if the battery is being charged via
the connecting points in the engine com-
partment (see page 141), the battery must
be connected.WARNING
PROPOSITION 65 WARNING!
Battery posts, terminals, and related acces-
sories contain lead and lead compounds,
chemicals known to the state of California
to cause cancer and reproductive harm.
Wash hands after handling.
1More frequently in warm climates.2The level indicator inside the battery could be designed in various ways. See illustrations.

Replacing bulbs
09``217
When replacing bulbs, keep the following
points in mind:•
Never touch the glass of bulbs with your
fingers. 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 Bi-Xenon headlight
bulbs contain trace amounts of mercury.
These bulbs should always be disposed of
by an authorized Volvo retailer.
•
The following bulbs should only be
replaced by a trained and qualified Volvo
service technician:
– Active Bi-Xenon headlights,
– Courtesy (dome) lighting,
– Reading lights,
– Glove compartment lights
– Turn signals and courtesy lights in the side
door mirrors
– High-mounted brake lights
Replacing high/low beams/turn signal/
parking light bulbs
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.
G027081
The entire lamp housing must be lifted out
when replacing these bulbs.
To lift out the lamp housing:1. Switch off the ignition.
2. Open the hood.
3. Pull up the retaining pins (see the illustra-
tion).
4. Lift out the lamp housing.
G027083
WARNING
Active Bi-Xenon headlights (option) - due to
the high voltage used by these headlights,
these bulbs should only be replaced by a
trained and qualified Volvo service techni-
cian.

ment *certain markets only(
If an electrical component fails to function, it is
possible that a fuse has blown.
The fuse boxes are located in four different
places, see the illustration above.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 (and several extra fuses) in the
passenger compartment fuse box on the driv-
er's end of dashboard. From the side, examine
the curved metal wire (see the illustration) 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 engine compartment and the passenger
compartment. 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.
