your vehicle diagnosed and, if necessary,
serviced by a qualified Volvo technician.
•
If you recently had service for a lit Check
Engine light, or if you had service that
required disconnecting the battery, a
period of driving is necessary to bring the
OBD II system to "ready" for inspection. A
half-hour trip of mixed stop-and-go/high-
way driving is typically needed to allow
OBD II to reach readiness. Your Volvo
retailer can provide you with more infor-
mation on planning a trip.
•
Maintain your vehicle in accordance with
your vehicle's maintenance schedule.

09 Maintenance and servicingEngine oil
09216
Changing engine oil and oil filterSee page 269 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 every time the
vehicle is refueled. This is especially important
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 capChecking 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
theMIN 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.

09 Maintenance and servicingFluids
09218
Washer fluid
G026425
Washer fluid reservoirThe washer fluid reservoir is located in the
engine compartment and holds approximately
6.8 US qts (6.5 liters). During cold weather, the
reservoir should be filled with windshield
washer solvent containing antifreeze.
Coolant
G020334
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 servicing
Fluids

219
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
G020333
Brake fluid reservoirThe 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.
Power steering fluidThe 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
Battery
09``221 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.

electrical system can be stored in the con-
trol modules.
