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 272 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 253.
•
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

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.

TEMPERATUREThe temperature grades are AA (the highest),
A, B, and C, representing the tire's resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled con-
ditions on a specified indoor laboratory test
wheel. Sustained high temperature can cause
the material of the tire to degenerate and
reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corre-
sponds to a minimum level of performance that
all passenger vehicle tires must meet under the
Federal Motor Safety Standard No. 109.
Grades B and A represent higher levels of per-
formance on the laboratory test wheel than the
minimum required by law.
WARNING
The temperature grade for this tire is estab-
lished for a tire that is properly inflated and
not overloaded. Excessive speed, under-
inflation, or excessive loading, either sepa-
rately or in combination, can cause heat
buildup and tire failure.
Snow chains, snow tires, studded tiresSnow chainsSnow chains can be used on your Volvo with
the following restrictions:•
Snow chains should be installed on front
wheels only. Use only Volvo approved
snow chains.
•
If accessory, aftermarket or "custom" tires
and wheels are installed and are of a size
different than the original tires and wheels,
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.

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.Temporary SpareThe spare tire in your vehicle is called a "Tem-
porary Spare".
Recommended tire pressure (see the placard
on the B-pillar or on the fuel filler door) should
be maintained irrespective of which position on
the vehicle the temporary spare tire is used on.In the event of damage to this tire, a new one
can be purchased from your Volvo retailer.
WARNING
Current legislation prohibits the use of the
"Temporary Spare" tire other than as a tem-
porary replacement for a punctured tire. It
must be replaced as soon as possible by a
standard tire. Road holding and handling
may be affected with the "Temporary
Spare" in use. Do not exceed 50 mph
(80 km/h).
CAUTION
The vehicle must not be driven with wheels
of different dimensions or with a spare tire
other than the one that came with the vehi-
cle. The use of different size wheels can
seriously damage your car's transmission.

The arrow shows the direction of rotation of the
tireSummer and winter tires•
When switching between summer and
winter tires, mark the tires to indicate
where they were mounted on the vehicle,
e.g. LF = left front, RR = right rear.
•
Tires with tread designed to roll in only one
direction are marked with an arrow on the
sidewall.
•
Incorrectly mounted tires impair the car's
braking properties and ability to force
aside rain, snow and slush.
•
The tires with the most tread should always
be at the rear (to reduce the risk of skid-
ding).
•
Contact a Volvo workshop if you are
unsure about the tread depth.
