Before a long distance tripIt is always worthwhile to have your vehicle
checked by a trained and qualified Volvo serv-
ice technician before driving long distances.
Your retailer will also be able to supply you with
bulbs, fuses, spark plugs and wiper blades for
your use in the event that problems occur.
As a minimum, the following items should be
checked before any long trip:
•Check that engine runs smoothly and that
fuel consumption is normal.
•Check for fuel, oil, and fluid leakage
•Have the transmission oil level checked.
•Check condition of drive belts.
•Check state of the battery's charge.
•Examine tires carefully (the spare tire as
well), and replace those that are worn.
Check tire pressures.
•The brakes, front wheel alignment, and
steering gear should be checked by a
trained and qualified Volvo service techni-
cian only.
•Check all lights, including high beams.
•Reflective warning triangles are legally
required in some states/provinces.
•Have a word with a trained and qualified
Volvo service technician if you intend to
drive in countries where it may be difficult
to obtain the correct fuel.
•Consider your destination. If you will be
driving through an area where snow or ice
are likely to occur, consider snow tires.
Cold weather precautionsIf you wish to check your vehicle before the
approach of cold weather, the following advice
is worth noting:
•Make sure that the engine coolant contains
50 percent antifreeze. Any other mixture
will reduce freeze protection. This gives
protection against freezing down to
–31 °F (–35 °C). The use of "recycled" anti-
freeze is not approved by Volvo. Different
types of antifreeze must not be mixed.
•Volvo recommends using only genuine
Volvo antifreeze in your vehicle's radiator.
•Try to keep the fuel tank well filled – this
helps prevent the formation of condensa-
tion in the tank. In addition, in extremely
cold weather conditions it is worthwhile to
add fuel line de-icer before refueling.
•The viscosity of the engine oil is important.
Oil with low viscosity (thinner oil) improves
cold-weather starting as well as decreas-
ing fuel consumption while the engine is
warming up. For winter use, 5W-30 oil, par-
ticularly the synthetic type, is recom-
mended. Be sure to use good quality oil but
do not use cold-weather oil for hard driving
or in warm weather, see page 295 for more
information on engine oil.
NOTE
Synthetic oil is not used when the oil is
changed at the normal maintenance inter-
vals except at owner request and at addi-
tional charge.
•The load placed on the battery is greater
during the winter since the windshield wip-
ers, lighting, etc. are used more often.
Moreover, the capacity of the battery
decreases as the temperature drops. In
very cold weather, a poorly charged bat-
tery can freeze and be damaged. It is there-
fore advisable to check the state of charge
more frequently and spray an anti-rust oil
on the battery posts.
•Volvo recommends the use of snow tires
on all four wheels for winter driving, see
page 235.
•To prevent the washer fluid reservoir from
freezing, add washer solvents containing
antifreeze. This is important since dirt is
often splashed on the windshield during
winter driving, requiring the frequent use of
the washers and wipers. Volvo Washer
Solvent should be diluted as follows: Down
to 14 °F (–10 °C): 1 part washer solvent and
4 parts water Down to 5 °F (–15 °C): 1 part
washer solvent and 3 parts water Down to
0 °F (–18 °C): 1 part washer solvent and

Checking the engine oil
The oil level should be checked at regular inter-
vals, particularly during the period up to the
first scheduled maintenance service.
•See page 295 for oil specifications.
•Refer to the Warranty and Service Records
Information booklet for information on the
oil change intervals.
Volvo recommends Castrol oil products.
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.
•Volvo does not recommend the use of
oil additives.
•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.
Checking and adding oil

Location of the filler cap and dipstick
NOTE
Before checking the oil:
•The car should be parked on a level sur-
face.
•If the engine is warm, wait for at least
10 – 15 minutes after the engine has
been switched off.
G021737
The oil level must be between the MIN and MAX
marks on the dipstick
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. The level must be between the
MIN and MAX marks.
3. Add oil if necessary. If the level is close to
the MIN mark, add approximately
0.5 US quarts (0.5 liters) of oil.
4. Recheck the level and add more oil if nec-
essary until the level is near the MAX mark.

295 Engine oil
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.
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 for recommendations on premium or
synthetic oils.
Oil additives must not be used.
Synthetic oil is not used when the oil is
changed at the normal maintenance services.
This oil is only used at customer request, at
additional charge. Please consult your Volvo
retailer.
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.

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.

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.
