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 274 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 251.
•
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

06 Maintenance and specifications
Maintaining your car
06``213 Owner maintenance
Periodic maintenance requirements and inter-
vals are described in your vehicle's Warranty
and Service Records Information booklet.
The following points can be carried out
between the normally scheduled maintenance
services.Each time the car is refueled:•
Check the engine oil level.
•
Clean the windshield, windshield wipers,
headlights, and tail lights.
Monthly:•
Check cold tire pressure in all tires. Inspect
the tires for wear.
•
Check that engine coolant and other fluid
levels are between the indicated "min" and
"max" markings.
•
Clean interior glass surfaces with a glass
cleaner and soft paper towels.
•
Wipe driver information displays with a soft
cloth.
•
Visually inspect battery terminals for cor-
rosion. Corrosion may indicate a loose ter-
minal connector, or a battery near the end
of its useful service life. Consult your Volvo
retailer for additional information.
As needed:Wash the car, including the undercarriage, to
reduce wear that can be caused by a buildup
of dirt, and corrosion that can be caused by salt
residues.
Clean leaves and twigs from air intake vents at
the base of the windshield, and from other pla-
ces where they may collect.
NOTE
Complete service information for qualified
technicians is available online for purchase
or subscription at www.volvotechinfo.com.Emission inspection readinessWhat is an Onboard Diagnostic System
(OBD II)?OBD II is part of your vehicle's computerized
engine management system. It stores diagnos-
tic information about your vehicle's emission
controls. It can light the Check Engine light
(MIL) if it detects an emission control "fault." A
"fault" is a component or system that is not
performing within an expected range. A fault
may be permanent or temporary. OBD II will
store a message about any fault.
How do states use OBD II for emission
inspections?Many states connect a computer directly to a
vehicle's OBD II system. The inspector can
then read "faults." In some states, this type of
inspection has replaced the tailpipe emission
test.How can my vehicle fail OBD II emission
inspection?Your vehicle can fail OBD II emission inspec-
tion for any of the following reasons.•
If your Check Engine (MIL) light is lit, your
vehicle may fail inspection.
•
If your vehicle's Check Engine light was lit,
but went out without any action on your
part, OBD II will still have a recorded fault.
Your vehicle may pass or fail, depending
on the inspection practices in your area.
•
If you had recent service that required dis-
connecting the battery, OBD II diagnostic
information may be incomplete and "not
ready" for inspection. A vehicle that is not
ready may fail inspection.
How can I prepare for my next OBD II
emission inspection?•
If your Check Engine (MIL) light is lit – or
was lit but went out without service, have

IntroductionYour vehicle is equipped with tires according
to the vehicle's tire information placard on the
B-pillar (the structural member at the side of
the vehicle, at the rear of the driver's door
opening).
The tires have good road holding characteris-
tics and offer good handling on dry and wet
surfaces. It should be noted however that the
tires have been developed to give these fea-
tures on snow/ice-free surfaces.
Certain models are equipped with "all-season"
tires, which provide a somewhat higher degree
of road holding on slippery surfaces than tires
without the "all-season" rating. However, for
optimum road holding on icy or snow-covered
roads, we recommend suitable winter tires on
all four wheels.
CAUTION
Some Volvo models are equipped with an
Ultra High Performance tire and wheel com-
bination designed to provide maximum dry
pavement performance with consideration
for hydroplaning resistance. As such, they
may be more susceptible to road hazard
damage and, depending on driving condi-
tions, may achieve a tread life of less than
20,000 miles (30,000 km). Even if this vehi-
cle is equipped with Volvo’s advanced AWD
or DSTC system, these tires are not
designed for winter driving, and should be
replaced with winter tires when weather
conditions dictate.When replacing tires, be sure that the new tires
are the same size designation, type (radial) and
preferably from the same manufacturer, on all
four wheels. Otherwise there is a risk of altering
the car's roadholding and handling characte-
ristics.Storing wheels and tiresWhen storing complete wheels (tires mounted
on rims), they should be suspended off the
floor or placed on their sides on the floor.
Tires not mounted on rims should be stored on
their sides or standing upright, but should not
be suspended.
CAUTION
Tires should preferably be stored in a cool,
dry, dark place, and should never be stored
in close proximity to solvents, gasoline, oils,
etc.Tread wear indicator
G021829
Tread wear indicatorThe tires have wear indicator strips running
across or parallel to the tread. The letters TWI
are printed on the side of the tire. When
approximately 1/16 " (1.6 mm) is left on the
tread, these strips become visible and indicate
that the tire should be replaced. Tires with less
than 1/16 " (1.6 mm) tread offer very poor trac-
tion.

06 Maintenance and specifications
Wheels and tires
06``243
When replacing worn tires, it is recommended
that the tire be identical in type (radial) and size
as the one being replaced. Using a tire of the
same make (manufacturer) will prevent altera-
tion of the driving characteristics of the vehicle.
WARNING
•
The wheel and tire sizes for your Volvo
are specified to meet stringent stability
and handling requirements. Unap-
proved wheel/tire size combinations
can negatively affect your vehicle's sta-
bility and handling. Approved tire sizes
are shown in the Tire inflation pressure
tables.
•
Any damage caused by installation of
unapproved wheel/tire size combina-
tions will not be covered by your new
vehicle warranty. Volvo assumes no
responsibility for death, injury, or
expenses that may result from such
installations.
New tires
G021823
Remember that tires are perishable goods. As
of 2000, the manufacturing week and year
(Department of Transportation (DOT) stamp)
will be indicated with 4 digits (e.g. 1502 means
that the tire illustrated was manufactured dur-
ing week 15 of 2002).Tire age•
Tires degrade over time, even when they
are not being used. It is recommended that
tires generally be replaced after 6 years of
normal service. Heat caused by hot cli-
mates, frequent high loading conditions or
Ultra Violet (U.V.) exposure can accelerate
the aging process.
•
You should replace the spare tire when you
replace the other road tires due to the
aging of the spare.
•
A tire's age can be determined by the DOT
stamp on the sidewall (see the illustration).
•
A tire with e.g., visible cracks or discolor-
ation should be replaced immediately.
Improving tire economy•
Maintain correct tire pressure. See the tire
pressure tables on pages 246 and 247.
•
Drive smoothly: avoid fast starts, hard
braking and tire screeching.
•
Tire wear increases with speed.
•
Correct front wheel alignment is very
important.
•
Unbalanced wheels impair tire economy
and driving comfort.
•
Tires must maintain the same direction of
rotation throughout their lifetime.
•
When replacing tires, the tires with the
most tread should be mounted on the rear
wheels to reduce the chance of oversteer
during hard braking.
•
Hitting curbs or potholes can damage the
tires and/or wheels permanently.

grades: See page 251 for more informa-
tion.
12. Maximum permissible inflation pressure:
the greatest amount of air pressure that
should ever be put in the tire. This limit is
set by the tire manufacturer.Glossary of tire terminologyThe tire suppliers may have additional mark-
ings, notes or warnings such as standard load,
radial tubeless, etc.•
Tire information placard: A placard
showing the OE (Original Equipment) tire
sizes, recommended inflation pressure,
and the maximum weight the vehicle can
carry.
•
Tire Identification Number (TIN): A num-
ber on the sidewall of each tire providing
information about the tire brand and man-
ufacturing plant, tire size and date of man-
ufacturer.
•
Inflation pressure: A measure of the
amount of air in a tire.
•
Standard load: A class of P-metric or Met-
ric tires designed to carry a maximum load
at 35 psi [37 psi (2.5 bar) for Metric tires].
Increasing the inflation pressure beyond
this pressure will not increase the tires load
carrying capability.
•
Extra load: A class of P-metric or Metric
tires designed to carry a heavier maximum
load at 41 psi [43 psi (2.9 bar) for Metric
tires]. Increasing the inflation pressure
beyond this pressure will not increase the
tire's load carrying capability.
•
kPa: Kilopascal, a metric unit of air pres-
sure.
•
PSI: Pounds per square inch, a standard
unit of air pressure.
•
B-pillar: The structural member at the side
of the vehicle behind the front door.
•
Bead area of the tire: Area of the tire next
to the rim.
•
Sidewall of the tire: Area between the
bead area and the tread.
•
Tread area of the tire: Area of the perim-
eter of the tire that contacts the road when
mounted on the vehicle.
•
Rim: The metal support (wheel) for a tire or
a tire and tube assembly upon which the
tire beads are seated.
•
Maximum load rating: a figure indicating
the maximum load in pounds and kilo-
grams that can be carried by the tire. This
rating is established by the tire manufac-
turer.
•
Maximum permissible inflation
pressure: the greatest amount of air pres-
sure that should ever be put in the tire. This
limit is set by the tire manufacturer.
•
Recommended tire inflation pressure:
inflation pressure, established by Volvo,
which is based on the type of tires that are
mounted on a vehicle at the factory. This
inflation pressure is affected by the number
of occupants in the vehicle, the amount of
cargo, and the speed at which the vehicle
will be driven for a prolonged period. This
information can be found on the tire infla-
tion placard(s) located on the driver's side
B-pillar or on the inside of the fuel filler door
on Canadian models, and in the tire infla-
tion table in this chapter.
•
Cold tires: The tires are considered to be
cold when they have the same temperature
as the surrounding (ambient) air. This tem-
perature is normally reached after the vehi-
cle has been parked for at least 3 hours.

06 Maintenance and specificationsWheels and tires

chains in some cases CANNOT be used.
Sufficient clearances between chains and
brakes, suspension and body components
must be maintained.
•
Some strap-on type chains will interfere
with brake components and therefore
CANNOT be used.
•
All Wheel Drive models: Snow chains
should only be installed on the front
wheels. Only chains adapted for AWD
models should be used.
Consult your Volvo retailer for additional snow
chain information.
CAUTION
•
Check local regulations regarding the
use of snow chains before installing.
•
Always follow the chain manufacturer's
installation instructions carefully. Install
chains as tightly as possible and
retighten periodically.
•
Never exceed the chain manufacturer's
specified maximum speed limit. (Under
no circumstances should you exceed
31 mph (50 km/h).
•
Avoid bumps, holes or sharp turns
when driving with snow chains.
•
The handling of the vehicle can be
adversely affected when driving with
chains. Avoid fast or sharp turns as well
as locked wheel braking.
Snow tires, studded tires

Tires for winter use:•
Owners who live in or regularly commute
through areas with sustained periods of
snow or icy driving conditions are strongly
advised to fit suitable winter tires to help
retain the highest degree of traction.
•
It is important to install winter tires on all
four wheels to help retain traction during
cornering, braking, and accelerating. Fail-ure to do so could reduce traction to an
unsafe level or adversely affect handling.
•
Do not mix tires of different design as this
could also negatively affect overall tire road
grip.
•
Winter tires wear more quickly on dry roads
in warm weather. They should be removed
when the winter driving season has ended.
•
Studded tires should be run-in
300 – 600 miles (500 – 1000 km) during
which the vehicle should be driven as
smoothly as possible to give the studs the
opportunity to seat properly in the tires.
The tires should have the same rotational
direction throughout their entire lifetime.NOTE
Please consult state or provincial regula-
tions restricting the use of studded winter
tires before installing such tires.
