09 Maintenance and servicing
Engine oil09

219 Changing engine oil and oil filter
See page 274 for oil specifications. Refer to
the Warranty and Service Records Information
booklet for information on the oil change inter-
vals.
Volvo recommends Castrol.
NOTE
•Volvo does not recommend the use of
oil additives.
•Synthetic oil is not used when the oil is
changed at the normal maintenance
intervals except at owner request and at
additional charge. Please consult a
trained and qualified Volvo service tech-
nician.
Checking and adding oilThe oil level should be checked at regular inter-
vals, particularly during the period up to the
first scheduled maintenance service.
•The car should be parked on a level surface
when the oil is checked.
•If the engine is warm, wait for at least
10–15 minutes after the engine has been
switched off before checking the oil.
G020338
Location of dipstick and oil filler cap
Checking the oil1. Pull out the dipstick and wipe it with a lint-
free rag.
2. Reinsert the dipstick, pull it out, and check
the oil level.
3. Add oil if necessary. If the level is close to
the MIN mark, add approximately
1 US quart (1 liter) of oil.
4. Run the engine until it reaches normal
operating temperature.
5. Switch off the engine and wait for at least
10–15 minutes and recheck the oil level. If
necessary, add oil until the level is near the
MAX mark.
G020336
CAUTION
•Not checking the oil level regularly can
result in serious engine damage if the oil
level becomes too low.
•Oil that is lower than the specified qual-
ity can damage the engine.
•Always add oil of the same type and
viscosity as already used.
•Never fill oil above the MAX mark. This
could cause an increase in oil consump-
tion.

Engine oil 09
220
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.

09 Maintenance and servicing
Fluids09

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.

09 Maintenance and servicing
Wiper blades09
223 Replacing windshield wiper blades
G020330
1. Fold out the wiper arm.
2. Press the button on the wiper blade attach-
ment and pull straight out (1), parallel with
the wiper arm.
3. Press a new wiper blade (2) until it clicks
into place.
4. Ensure the blade is securely attached (3).
5. Fold in the wiper arm.
The wiper blades are different lengths. The
blade on the driver's side is longer than the one
on the passenger's side.
G020329
Keeping the windshield wiper blades clean
helps improve visibility and prolongs the serv-
ice life of the wiper blades. See page 206 for
washing instructions.

09 Maintenance and servicing
Battery 09
224
Battery maintenance
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:
Check the fluid level in each cell in the battery
every 24 months or every 15,000
1 miles
(24,000 km), whichever is sooner.
•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.
•The fluid level should be checked if the
battery has been recharged.
•After inspection, be sure the cap over each
battery cell or the cover is securely in
place.
•Check that the battery cables are correctly
connected and properly tightened.
•Never disconnect the battery when the
engine is running, or when the key is in the
ignition. This could damage the vehicle's
electrical system.
•The battery should be disconnected from
the vehicle when a battery charger is used
directly on the battery.
•To help keep the battery in good condition,
the vehicle should be driven for at least 15
minutes a week or connected to a charger
with an automatic charging function.
•If the battery is fully discharged a number
of times, this may shorten its service life.
Keeping the battery fully charged helps
prolong its service life.
•The service life of a battery is affected by
factors such as driving conditions and cli-
mate. Extreme cold may also further
decrease the battery’s starting capacity.
•Because the battery’s starting capacity
decreases with time, it may be necessary
to recharge it if the vehicle is not driven for
an extended period of time or if the vehicle
is usually only driven short distances.
